Description

[Technical Field]

[0001] The present invention relates to the treatment or prevention of parasitic infections in animals. [Background technology]

[0002] Parasitic infection of fish is a major problem in commercial fish farming. Fish farmers who face parasite problems usually suffer significant financial losses and incur additional costs.

[0003] Fish lice are ectoparasites belonging to the subclass Copepoda that negatively impact fish, particularly farmed salmonids, by feeding on the mucous membranes, skin, tissues, and blood of their host fish. Fish lice can cause significant damage to the host fish (i.e., severe fin damage, skin erosion, bleeding, and open wounds). Furthermore, fish lice can induce a chronic stress response in fish, which in turn can make the fish more susceptible to other diseases. Furthermore, fish lice have immunomodulatory effects in their host fish and appear to be capable of functioning as vectors in the transmission of other fish diseases. Damage caused by parasitic infections from fish lice results in significant animal welfare issues, fish losses, and increased costs. Infection with fish lice is considered one of the most important disease problems in salmonid aquaculture, especially in Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss).

[0004] Infestation by fish lice can also occur in other species of fish, for example, sea bass, tilapia, carp, etc. In addition to the costs associated with treatment, lowered taxonomic ratings of slaughtered fish and reduced growth rates due to reduced feeding contribute to economic losses.

[0005] Fish lice, on the other hand, are widespread and encountered in all fish farming operations. Severe infestations result in fish mortality. Mortality rates of over 50% due to fish lice infestation have been reported in Norwegian fish farms. The severity of damage depends on the season and environmental factors, such as water salinity and average water temperature. In the first phase, fish lice infestation is seen in the appearance of parasites attached to the fish, and later—even more obviously—in the damage caused to the skin and tissues. The most severe damage is observed in smolts just as they transition from freshwater to seawater. This situation is even worse due to the specific conditions in fish farms where salmon of different age groups but the same weight class are kept together; here, contaminated nets or cages are used; high salt concentrations are likely to be present; flow through the nets and cages is minimal, and the fish are kept in very small spaces.

[0006] Many treatments for controlling body lice are already on the market, including bath treatments such as organophosphates (e.g., dichlorvos and azamethiphos) and pyrethroids (e.g., cypermethrin and deltamethrin), and feed treatments such as avermectins (e.g., ivermectin and emamectin benzoate) and growth regulators (e.g., lufenuron and teflubenzuron). However, resistance to many of these treatments has been observed, and therefore new treatments, particularly those with a longer duration of action, remain needed.

[0007] Therefore, there remains a need for new treatment options for controlling fish lice infestations in fish, particularly farmed fish populations, that are safe, selective for the target parasite, and capable of treating fish lice populations that are resistant or have reduced susceptibility to current products. The present invention provides a new treatment option for the control of fish lice in fish.

[0008] WO 2016 / 168056, WO 2016 / 168058, WO 2016 / 168059 and WO 2018 / 071327 disclose certain aromatic compounds as having insecticidal and acaricidal activity and therefore useful in controlling pests of agricultural plants, but none of these references exemplify or describe their use in aquaculture.

[0009] Surprisingly, it has been found that aromatic cyclopropylamide compounds of formula (I) are effective for combating parasitic infections in fish, particularly fish lice infestations. Summary of the Invention

[0035] The advantage of such a method is that it is effective in both treating existing body lice infestations and preventing new infestations, thus preventing the establishment of adult body lice colonies, which are known to be the most damaging stage. The resistance-busting properties of such compounds are highly desirable.

[0036] Surprisingly, it has been found that the cyclopropylamide compounds of formula (I) as described in any embodiment herein are effective against juvenile and adult fish lice in fish and can be used successfully, while having low toxicity to fish.

[0037] A further advantageous property of the compounds of formula (I) as described in any embodiment herein is that at the proposed concentrations they do not harm other marine animals such as lobsters, oysters, crustaceans (except fish lice), fish and marine plants.

[0038] As shown in the examples, administration of aromatic cyclopropylamide compounds of formula (I) as described herein can effectively control fish lice infestations using oral administration, particularly when using medicated bait administration containing the compounds of the present invention and fish bait. Furthermore, it has been shown that compounds of formula (I) as described herein can be effectively used to control resistant populations of fish parasites.

[0039] The present invention is therefore advantageous in the control of fish parasites, particularly fish lice, and allows for the effective control of fish lice in fish populations.

[0040] The cyclopropylamide compounds of formula (I) or veterinarily acceptable salts thereof as described in any embodiment herein may be used to control parasitic infections in fish. Uses according to the present invention are described in detail below.

[0152] Salts, solvates, N-oxides and prodrugs A salt of a cyclopropylamide compound of formula (I) or another compound may be advantageous due to one or more physical properties of the salt, such as pharmaceutical stability at different temperatures and humidities; crystalline properties; and / or desired solubility in water, oil, or other solvents. In some cases, a salt may be used as an aid in the isolation, purification, and / or resolution of the compound. Acid and base salts can generally be formed, for example, by mixing the compound with an acid or base, respectively, using various methods known in the art. To the extent that a salt of the compound is intended to be administered in vivo (i.e., to an animal) for therapeutic benefit, the salt is pharmaceutically acceptable.

[0153] Salts may also be advantageous in the synthesis of compounds according to the invention, for example certain intermediates may be advantageously used in the form of their salts in the process for the preparation of compounds according to the invention.

[0154] Generally, acid addition salts can be prepared by reacting a free base compound with an approximately stoichiometric amount of inorganic or organic acid.Examples of inorganic acids that are often suitable for preparing (pharmaceutically acceptable) salts include hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, carbonic acid, sulfuric acid, and phosphoric acid.Examples of organic acids that are often suitable for preparing (pharmaceutically acceptable) salts generally include, for example, aliphatic, alicyclic, aromatic, araliphatic, heterocyclic, carboxy, and sulfonic classes of organic acids. Specific examples of organic acids that are often suitable include cholic acid, sorbic acid, lauric acid, acetic acid, trifluoroacetic acid, formic acid, propionic acid, succinic acid, glycolic acid, gluconic acid, digluconic acid, lactic acid, malic acid, tartaric acid, citric acid, ascorbic acid, glucuronic acid, maleic acid, fumaric acid, pyruvic acid, aspartic acid, glutamic acid, arylcarboxylic acids (e.g., benzoic acid), anthranilic acid, mesylic acid, stearic acid, salicylic acid, p-hydroxybenzoic acid, phenylacetic acid, mandelic acid, embonic acid (pamoic acid), alkylsulfonic acids (e.g., ethanesulfonic acid), arylsulfonic acids, and the like. Examples of suitable salts include carboxylic acids (e.g., benzenesulfonic acid), pantothenic acid, 2-hydroxyethanesulfonic acid, sulfanilic acid, cyclohexylaminosulfonic acid, β-hydroxybutyric acid, galactaric acid, galacturonic acid, adipic acid, alginic acid, butyric acid, camphoric acid, camphorsulfonic acid, cyclopentanepropionic acid, dodecylsulfuric acid, glycoheptanoic acid, glycerophosphoric acid, heptanoic acid, hexanoic acid, nicotinic acid, 2-naphthalsulfonic acid, oxalic acid, palmoic acid, pectinic acid, 3-phenylpropionic acid, picric acid, pivalic acid, thiocyanic acid, tosylic acid, and undecanoic acid. In some such embodiments, for example, the salt comprises a salt of trifluoroacetic acid, mesylic acid, or tosylic acid. In other embodiments, the salt comprises a hydrochloride salt.

[0155] Generally, base addition salts can be prepared by reacting a free acid compound with an approximately stoichiometric amount of an inorganic or organic base. Examples of base addition salts include, for example, metal salts and organic salts. Metal salts include, for example, alkali metal (group Ia) salts, alkaline earth metal (group IIa) salts, and other physiologically acceptable metal salts. Such salts can be made from aluminum, calcium, lithium, magnesium, potassium, sodium, and zinc. For example, a free acid compound can be mixed with sodium hydroxide to form such a base addition salt. Organic salts can be made from amines such as trimethylamine, diethylamine, N,N'-dibenzylethylenediamine, chloroprocaine, ethanolamine, diethanolamine, ethylenediamine, meglumine (N-methylglucamine), and procaine. Basic nitrogen-containing groups may be quaternized with agents such as C1-C6-alkyl halides (e.g., methyl, ethyl, propyl, and butyl chlorides, bromides, and iodides), dialkyl sulfates (e.g., dimethyl, diethyl, dibutyl, and diamyl sulfate), long-chain halides (e.g., decyl, lauryl, myristyl, and stearyl chlorides, bromides, and iodides), arylalkyl halides (e.g., benzyl and phenethyl bromide), and the like.

[0156] Solvates of the cyclopropylamide compounds of formula (I) or of other compounds may be formed by aggregation of said compounds of formula (I) with solvent molecules, preferably in limited weight proportions, such as water, alcohols, e.g., ethanol, aromatic solvents, e.g., toluene, ethers, halogenated organic solvents, e.g., dichloromethane.

[0157] N-oxides of compounds of formula (I) or other compounds may be formed by oxidation of the N atom in an amine or an N-heterocycle, such as pyridine, with an oxidizing agent such as hydrogen peroxide, a peracid, or an inorganic oxidizing agent such as potassium peroxymonosulfate (oxone).

[0158] The present invention also encompasses prodrug derivatives of the cyclopropylamide compounds of formula (I). The term prodrug refers to a compound that is converted in vivo to yield the parent compound of formula (I). In vivo means that this conversion can occur in the host organism and / or the parasite, for example, in the case of treating a parasitic infection. Various forms of prodrugs are well known in the art. For example, when the group of formula (A) represents pyridine, pyridinium salts, such as acyloxyalkylpyridinium salts, can be formed, which can provide the advantage of higher solubility in parenteral dosage forms, as described in SK Davidsen et al., J. of Med. Chem. 37 4423-4429 (1994).

[0159] Isomers The compounds according to the invention or intermediates thereof may exist in different isomeric forms. Any reference to a compound according to the invention or an intermediate thereof includes all possible isomeric forms of such compound.

[0160] In some embodiments, such compounds may have two or more isomers, such as optical isomers or stereoisomers. In some preferred embodiments, such compounds have the (E) configuration, and in other embodiments, the compounds have the (Z) configuration. In preferred embodiments, the compounds have the (E) configuration.

[0161] Unless otherwise stated, a compound structure that does not depict a particular conformation is intended to encompass all possible conformational isomers of the compound, and may include fewer than all possible conformational isomers. Compounds with two chiral centers have four isomers: RR-, SS-, RS-, and SR-isomers. Such compounds can exist in several forms, i.e., as pure RR or SS or RS or SR isomers, or as mixtures hereinafter referred to as "enantiomeric pairs," either RR / SS or RS / SR.

[0162] Cyclopropylamide compounds can exist as a racemic mixture of all four isomers (RR+SS+RS+SR) or as a racemic mixture of the enantiomer pairs (RR / SS) or (RS / SR). The isomers (RR) and (SS) are mirror images of each other and are therefore enantiomers, which have the same chemical properties and melting points. (RS) and (SR) are also an enantiomer pair. However, the mirror images of (RR) and (SS) are not superimposable in (RS) and (SR). This relationship is called diastereomeric, and (RR) is a diastereomer of (RS).

[0163] Although structurally identical, isomers may have different effects in biological systems: one isomer may have specific therapeutic activity, while another may have no therapeutic activity or may have an entirely different form of biological activity.

[0164] It has now been surprisingly found that parameters such as efficacy can be significantly improved by administering the pure or substantially pure RR-isomer of the present compound or a pharmaceutically acceptable salt thereof, while side effects can be substantially avoided. Thus, the applicants have found that by administering a therapeutically effective amount of the pure or substantially pure RR-isomer of the present compound or a pharmaceutically acceptable salt thereof.

[0165] Terms such as "pure RR-cyclopropylamide compound," "pure RR isomer of cyclopropylamide compound," and the like refer to cyclopropylamide compounds having the optical purity of the RR-cyclopropylamide compound of formula (I), i.e., 98% by weight or greater, meaning that the RR isomer is present in a concentration of 98% by weight or greater, based on the total amount of cyclopropyl compound present, while the total concentration (i.e., sum) of the corresponding RS-, SR-, and SS-isomers is 2% by weight or less.

[0166] The terms "substantially pure RR-cyclopropylamide compound," "substantially pure RR isomer of cyclopropylamide compound," and the like refer to an optical purity of the RR-* cyclopropylamide compound that is 80% by weight or greater, meaning that the concentration of the RR-cyclopropylamide compound is 80% by weight or greater and the sum of the corresponding RS-, SR-, and SS-isomers is 20% by weight or less, based on the total amount of cyclopropylamide compound present. In a more preferred embodiment, a "substantially pure RR-cyclopropylamide compound" contains 90% by weight or greater of the RR-cyclopropylamide compound and 10% or less of the sum of the RS, SR, and SS-isomers of the cyclopropylamide compound.

[0198] definition The following definitions are important in connection with embodiments of the present invention.

[0199] definition "Parasite" A parasite is an organism that lives on or in another organism (usually called a host) causing harm to the host. As used herein, unless otherwise indicated, refers to endoparasites and ectoparasites. Endoparasites are parasites that live inside their host's body and include helminths (e.g., trematodes, cestodes, and nematodes) and protozoa. Ectoparasites are organisms that feed through or on the skin of their host. In the present invention, the host animal is a fish.

[0200] "Fish," as used herein, unless otherwise indicated, refers to the taxonomic classes Chondrichthyes (cartilaginous fish, e.g., sharks and ray-finned fish) and Osteichthyes (bony fish), which live in water, have gills for breathing or mucus-coated skin, and may have scales. This includes food fish, breeding fish, and aquarium fish, pond fish, and farmed fish of all ages occurring in freshwater, saltwater (e.g., ocean), and brackish water.

[0201] Non-limiting examples of food fish include carp, eel, trout, whitefish, salmon, roach, rudd, chub, Arctic char, sturgeon, plaice, halibut, turbot, flounder, striped bass, yellowtail, grouper, cod, flounder, tuna, red sea bream, sea bass, grey mullet, trevally, gilthead sea bream, tilapia, and catfish.

[0202] The present invention more particularly relates to marine fish and more particularly marine food fish, especially salmon.

[0203] Within the scope of the present invention, the term "salmon" is understood to include all representatives of the family Salmonidae, in particular the following species: Salmo salar (Atlantic salmon); Salmo trutta (brown or sea trout); Salmon gairdneri (rainbow trout); and Pacific salmon (Oncorhynchus): O. gorbuscha; O. keta; O. nekra; O. kisutch, O. tshawytscha, and O. mason; as well as artificially propagated species such as Salvelinus spp. and Salmo clarkia.

[0204] The preferred hosts of the present invention are Atlantic and Pacific salmon and sea trout.

[0205] In another embodiment, the host fish is Mediterranean sea bass and / or sea bream. In another embodiment, the host fish is a freshwater fish such as carp and / or freshwater trout. In another embodiment, the fish is tilapia.

[0206] Fish population means a group of individual fish maintained in a limited area, such as in seawater tanks, cages or nets. The cages and nets are fixed at the entrance to the ocean to allow a daily periodic current of water to pass through them to ensure an adequate supply of oxygen and clean water.

[0207] The tanks have a continuous flow of seawater into and out of them, or at least scheduled flushes of fresh seawater, to ensure sufficient water quality and oxygen to keep the fish healthy. In this artificial environment, the fish are fed and provided with medication, if necessary, until they are mature enough for sale as food fish or selected for further breeding.

[0208] In one embodiment of the present invention, the compound of formula (I) or a salt, enantiomer or prodrug thereof is administered to a population of fish at the end of the freshwater phase or the beginning of the saltwater phase in fish farming.

[0209] According to another embodiment, the fish (salmon or sea trout) are maintained in seawater while the treatment is carried out.

[0210] Fish lice According to the present invention, the compounds of formula (I) are particularly suitable for use in the control of fish-parasitic crustaceans, such as fish lice, etc. Thus, in one embodiment, the compounds of formula (I) are used to control fish-parasitic crustaceans, particularly fish lice infestations.

[0211] Fish lice is the common name given to a group of fish-parasitic crustaceans, the copepods, which are ectoparasites that affect fish in saltwater. "Fish lice," as used herein, unless otherwise indicated, refers to a parasitic crustacean (copepod) that feeds through or on the mucus, skin, and tissues of its host, and is in the order Siphonostomatoida.

[0212] These include the families Caligidae and Lernanthropidae. Two representatives of the Caligidae family cause considerable losses in salmonid aquaculture: Lepeophtheirus spp. and Caligus spp. (C). Species within Lepeophtheirus spp. (L) include, for example, Lepeophtheirus salmonis oncorhynchi, Lepeophtheirus salmonis Lernanthropus koyeri, and species within Caligus spp. include, for example, Caligus clemensi, Caligus curtus, Caligus dussumieri, Caligus elongatus, Caligus longicaudatus, Caligus rogercresseyi, and Caligus stromii. stromii and Caligus minimus.

[0213] L. salmonis is found only in the Northern Hemisphere. C. rogercresseyi is the most important species of fish lice in Chile affecting the salmon industry.

[0214] One representative of the family Lernanthropidae is of interest mainly in Mediterranean fish farming: Lernanthropus spp. Species within Lernanthropus spp. include, for example, Lernanthropus kroyeri, Lernanthropus callinomymicola, Lernanthropus indefinitus, Lernanthropus cynoscicola, and Lernanthropus gisleri.

[0215] In one embodiment, the compounds are used to control fish lice infestations, wherein the fish lice are at least one of Lepeophtheirus salmonis, Caligus clemensi, Caligus curtus, Caligus dussumieri, Caligus elongatus, Caligus longicaudatus, Caligus rogercresseyi, or Caligus stromii, Caligus minimus, or Lernanthropus kroyeri.

[0216] In another embodiment, the compound is used to control a crustacean parasitic infection in a fish, wherein the crustacean parasitic in the fish is at least one of Lepeophtheirus kroyeri and Caligus minimus.

[0217] It has been found that the compounds of formula (I) are capable of controlling various stages of crustaceans that parasitize fish, in particular fish lice.

[0218] In one embodiment, the compounds of formula (I) are used to control fish lice infestations in crustaceans parasitic on fish, particularly copepodids, pre-adult or adult fish lice, or mixed infections at various stages.

[0219] Crustaceans that parasitize fish, such as the ascarid fish louse, have both free-swimming (planktonic) and parasitic life cycles, all separated by molting.

[0220] The eggs hatch into nauplii larvae I, which molt to a second nauplii stage; both nauplii rely on yolk stores for energy, do not feed, and are adapted to swimming. The next life cycle, the copepodid stage, is the infective stage, and the organism seeks out suitable hosts, presumably by chemical and mechanosensory cues.

[0221] Transmission of caligid fish lice occurs during the planktonic copepod stage (larvae). Once the copepod attaches to a suitable host, it feeds before molting into the Calimus I stage. Fish lice continue their development through up to four Calimus stages by molting. A distinctive feature of all Calimus stages is that they are physically attached to the host by a structure called a frontal thread. Differences in the timing, method of production, and physical structure of the frontal threads are found among individual species of fish lice.

[0222] Except for a brief period during molting, pre-adults and adult stages are mobile on the fish and, in some cases, may be transferred between host fish. Larger adult females occupy a relatively flat body surface on the posteroventral and dorsal midline and in the head region.

[0223] Until they locate the host, the nauplii and copepodid stages do not feed and subsist on internal food reserves. Once attached to a host, the copepodid stage begins feeding and develops into the first charimid stage. The copepods and charimid stages have developed digestive tracts and feed on host mucus and tissue within their attachment (the sessile stage). Pre-adult and adult fish lice, especially egg-laying females, are aggressive feeders, in some cases feeding on blood in addition to tissue and mucus.

[0224] As used herein, "juvenile fish lice" refers to the stage before an individual matures to the pre-adult and adult stages, and includes the copepodid and charimid parasitic forms of fish lice.

[0225] As used herein, the term "sessile stage" refers to the juvenile and "mobile" stages - pre-adult and adult stages.

[0226] In one embodiment, existing infections in fish populations with motile stages such as adult fish lice stages and / or pre-adult stages are treated, which is particularly important as these parasite stages cause the most significant damage when feeding on fish.

[0227] Infection of a fish means that members of at least one parasite stage are visible on the surface of the fish. In special cases, automated fish lice counting methods can be used to detect infection and the extent of fish lice infestation by parasite counting.

[0228] In an alternative preferred embodiment, existing infestations of fish populations with juvenile fish lice (sessile stage) as determined by fish lice counting methods are treated. Such control of juvenile fish lice infestations is desirable as control of the juvenile stage provides longer term protection to the fish from pre-adult or adult fish lice development in the fish, particularly from adult female fish lice.

[0229] In another embodiment, existing infestations of fish populations with juvenile fish lice (sessile stage) and adult stages (mobile stage) are treated.

[0230] In one embodiment, a single administration of a compound of formula (I) protects a fish population from re-infection with parasites, particularly fish lice, for a period of 4 weeks, allowing for a 4 week interval between treatments (i.e., the time between administrations is 4 weeks).

[0231] In one embodiment, the time between administrations is 2 to 8 weeks, preferably 3 to 6 weeks, and more preferably about 4 weeks. Reinfection means that an individual has been infected with a particular parasite and then a different parasite infection from the environment or contact with infected fish or equipment is established on the same animal.

[0232] In another embodiment, the parasite is Argulus spp., Argulus (carp lice), Lernaea, and Ergasilus, belonging to the class Crustacea, and considered to be important ectoparasites on fish. The parasitic copepods, Argulus and Lernaea, attach themselves to the body of the fish, their bodies embedded in the scale sac, and paired egg sacs protruding freely. Argulus spp. attach themselves to the body of the fish particularly by suckers and hooks, but can also swim freely in the water.

[0233] pest control As used herein, the term "control" refers to reducing the number of parasites, particularly the number of fish parasitic crustaceans, particularly fish lice, eliminating parasites, particularly fish parasitic crustaceans, particularly fish lice, and / or preventing further infection, particularly infection by pre-adult and adult stages of fish parasitic crustaceans, particularly fish lice.

[0234] "Treatment" refers to prophylactic or reactive treatment, such as the control, elimination, protection from, and / or prevention of fish parasitic (e.g., fish lice) infection or condition in fish or fish populations. This term includes reducing the average number of parasites (e.g., fish lice) infecting each fish in a fish population; or preventing an increase in the average number of parasites currently infecting each fish in a fish population; i.e., treating an existing parasitic infection or additionally or alternatively preventing the onset of symptoms associated with a parasitic infection, including reducing the severity of infection by a parasite (e.g., fish lice) or a disorder, condition, or symptom associated with a parasitic infection. This term also includes preventing the recurrence of a fish parasitic infection or symptoms associated therewith, as well as references to "control" (e.g., killing, dispelling, expelling, incapacitating, deterring, removing, mitigating, minimizing, and eradicating).

[0235] In most countries, salmon producers are obliged to regularly report their fish lice levels and treatment data. Local regulations, for example, require weekly sampling of at least five fish per net pen from a minimum of six net pens when water temperatures exceed 5°C. In all cases, fish-level fish lice counts are reported for different parasite life cycles: charimus, pre-adult males, and females, along with adult males (PAAM) and adult females (AF; both spawning and non-spawning). In Norway, fish populations are treated if an average of more than 0.5 adult female fish lice per fish is detected in an aquaculture facility, also known as a fish farming site. In Scotland, there is a mandatory requirement that if an average of three adult female fish lice per fish is found during weekly counts at any fish farming site, this must be reported.

[0236] In a preferred embodiment, compounds of formula (I) are used to control fish lice infestations in aquaculture facilities where the infestation rate in fish populations averages 0.5 to 3 adult female fish lice per fish.

[0237] Effective dose and route of administration As used herein, the term "effective amount" refers to the amount or dose of a compound of formula (I) or a salt thereof to a fish or population of fish in single or multiple administrations that produces the desired effect.

[0238] In determining the effective amount, numerous factors are considered, including, but not limited to, the species of fish; the degree of parasitic infection; the response of the fish population; the mode of administration; the bioavailability characteristics of the administered preparation; the selected dosing regimen; the use of co-medications; and other appropriate circumstances.

[0239] "Therapeutically effective amount," as used herein, unless otherwise indicated, refers to an amount that (i) treats a specific parasitic infection, (ii) reduces, ameliorate, or eliminates one or more symptoms of a specific parasitic infection, or (iii) prevents or delays the onset of one or more symptoms of a specific parasitic infection described herein.

[0240] The compounds of formula (I) or salts thereof may be administered to fish by any route which has the desired effect, including, but not limited to, oral administration, parenteral administration by intraperitoneal or intramuscular injection, or topical administration, for example in the form of a medicated bath.

[0241] Thus, in one embodiment, the compounds are applied to the fish orally, topically, for example, by medicated bath treatments, which include immersing the fish in water containing a therapeutically effective amount of the compound (medicated water) or injecting the fish intraperitoneally or intramuscularly.

[0242] In one embodiment, the fish are treated orally, e.g., via their food. Alternatively, they are treated topically, e.g., by bath treatment in a "medicated bath" into which the fish are placed and maintained for a period of time (minutes to hours), e.g., when transferred from one breeding tank to another.

[0243] In certain cases, treatment can also be carried out parenterally, for example by injection, such as by intraperitoneal or intramuscular injection. It is also possible to treat the fish biotope, for example the net cage, the entire pond, aquarium, tank or bath in which the fish are kept, either transiently or continuously.

[0244] One aspect of the present invention is a composition comprising one or more compounds of formula (I) and veterinarily acceptable formulation adjuvants for use in controlling parasitic infections in fish populations.

[0245] "Veterinarily acceptable," as used herein, unless otherwise indicated, indicates that a component must be chemically and / or toxicologically compatible with other ingredients comprising the composition, the composition, and / or the fish treated therewith. The term "pharmaceutically" acceptable has the same meaning as given for "veterinarily" acceptable.

[0246] The compositions include those suitable for the aforementioned routes of administration. The compositions may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the veterinary arts. In general, the compositions are prepared by uniformly and intimately bringing into association the active ingredients with liquid carriers or finely divided solid carriers, or both, and then, if necessary, shaping the product.

[0247] The compounds are administered in compositions tailored to the application. Compositions for oral administration may consist, for example, of powders, granules, solutions, emulsions or suspensions that are uniformly mixed with the feed as a feed additive, or powders, granules, solutions, emulsions or suspensions that are administered in pill form, such as a fish feed composition, the outer coating of which completely covers the active compound.

[0248] Compositions for bath application or for treating biotopes are powders, granules, solutions, emulsions or suspensions, tablets or the active compound itself.

[0249] The compositions are generally prepared in a manner known per se by mixing, granulating and / or molding the active compound with a solid or liquid carrier, optionally with further adjuvants, such as emulsifiers or dispersing agents, solubilizers, colorants, antioxidants and / or preservatives.

[0250] In fact, it is also possible to use forms of application in which the active compound is contained in a film matrix that is readily soluble in water or in a film in which it disperses over the application period.

[0251] The diluted compositions of the present invention are prepared by contacting the compound of formula (I) with the adjuvants of liquid and / or solid compositions by stepwise mixing and / or grinding so as to achieve optimal expression of the antiparasitic activity of the composition compatible with the application.

[0252] Bath application of the compositions of the present invention to the parasites to be controlled can be carried out, for example, by placing the composition in the cage in the form of a solution, emulsion, suspension, powder or tablet, which is rapidly dissolved and dispersed by the movement of the fish and the current of the water.

[0253] Medicated bath treatment The compounds of formula (I) may be administered to fish by bath treatment, for example by placing the fish in a "medicated bath" and maintaining them for a period of time (minutes to hours), for example when transferring them from one net pen or breeding tank to another.

[0254] Thus, in one embodiment, an effective amount of at least one compound of formula (I) is administered to the fish by topical administration, preferably by immersion of the fish in water containing a therapeutically effective amount of one or more compounds of formula (I). For use as a medicated bath treatment, a compound of formula (I) or a composition comprising at least one compound of formula (I), at least one compound of formula (I) may be dissolved or suspended in water containing the fish and / or parasites, thereby forming a medicated water.

[0255] Another aspect of the present invention is a composition comprising at least one compound of formula (I) for dilution for use as a water bath immersion treatment to control parasitic infestations on fish from fish lice.

[0256] In one embodiment, such compositions comprise one or more compounds of Formula (I) and veterinarily acceptable formulation adjuvants in the form of a stock solution for dilution in a volume of water to form medicated water for use as a bath immersion treatment. Preferably, the effective amount in the medicated water is from about 2 ppb to about 500 ppb.

[0257] In one embodiment, a stock solution is used, which is a concentrated solution of the compound in a liquid carrier containing a solvent and solubilizing agent, which can be diluted with a large amount of water.

[0258] In yet another aspect of the invention, the composition is a stock solution of a compound of formula (I) for dilution in the volume of water to be used as a water bath immersion treatment to control parasitic fish lice infestations on fish.

[0259] In another aspect of the invention, a stock solution of a compound of formula (I) comprises a solvent and optionally a solubilizing agent.

[0260] The solvent may be a non-aqueous polar solvent such as methanol, ethanol, benzyl alcohol, isopropanol, acetone, methylene chloride, butyl diglycol, N-methyl-2-pyrrolidone, dimethylacetamide, dimethylformamide, dimethyl sulfoxide, polyoxyethylated ethers, propylene glycol, ethylene glycol, and mixtures thereof. In another aspect of the invention, the non-aqueous polar solvent is selected from ethanol, benzyl alcohol, isopropanol, acetone, butyl diglycol, N-methyl-2-pyrrolidone, dimethylacetamide, dimethylformamide, dimethyl sulfoxide, and mixtures thereof. In another aspect of the invention, the non-aqueous polar solvent is selected from benzyl alcohol, butyl diglycol, N-methyl-2-pyrrolidone, dimethyl sulfoxide, and mixtures thereof.

[0261] The composition may further comprise a solubilizer such as polyoxyethylene castor oil derivatives, polysorbates, (caprylic / capric) glycerides, poloxamers, polyoxyethylene alkyl ethers, polyoxylglycerides, sorbitan fatty acid esters, polyoxyethylated 12-hydroxystearic acid, propylene glycol esters, polyglycerol esters, polyvinylpyrrolidone, cyclodextrin, polyethylene glycol, glyceryl stearate, caprylic glyceride, glyceryl monooleate, capric glyceride, alcohol ethoxylates, and mixtures thereof.

[0262] The compound of formula (I) can be used to prepare immersion baths with different concentrations of the compound of formula (I) to achieve the required dosage concentration. The stock solution can be diluted at least once before mixing with water, or can be poured directly into the volume of water for treatment of the fish.

[0263] The concentration of the compound during application to the fish depends on the type and duration of treatment, and also on the age and condition of the fish being treated. Typical immersion times range from about 15 minutes to about 4 hours, preferably from about 15 minutes to 2 hours, and more preferably from about 30 minutes to about 1 hour.

[0264] The compounds of formula (I) may be used in a water bath in a therapeutically effective amount or concentration of about 2 ppb to about 500 ppb in water, based on the total volume of water; or about 5 ppb to about 500 ppb; or about 5 ppb to about 250 ppb; or about 5 ppb to about 200 ppb; or about 5 ppb to about 100 ppb; or about 5 ppb to about 90 ppb; or about 5 ppb to about 80 ppb; or about 5 ppb to about 60 ppb; or about 5 ppb to about 50 ppb; or about 5 ppb to about 40 ppb; or about 5 ppb to about 25 ppb.

[0265] All effective concentrations are in parts per billion (ppb) measured in a volume of water (fresh, salt, brackish) for treating fish against copepod crustacean species, particularly fish lice. The concentrations are achieved by adding a volume of a concentrated stock solution of the compound of formula (I), for example, 50 mg / ml or 100 mg / ml, to a container containing fish. Those skilled in the art can determine how much stock solution of the compound to add based on knowledge of the volume of the container containing the fish and the concentrate of the stock solution.

[0266] Medicated baits, premixes The active compounds in these compositions are used in pure form, e.g. as solid active compounds of a specific particle size, or preferably together with at least one adjuvant conventionally used in formulation technology, e.g. a bulking agent, generally a solvent or solid carrier or a surface-active compound (surfactant).

[0267] The compound may be added to the feed by simple mixing as a pure compound, such as a powder, in the usual manner, or may be mixed with an edible, non-toxic, veterinarily acceptable excipient in the form of a veterinary composition, and may be included as a premix in the form of a solution or suspension, granules, pellets.

[0268] In one embodiment of the present invention, the compound of formula (I) or a salt thereof is administered in medicated fish bait.

[0269] Therefore, another embodiment is a composition comprising one or more compounds of formula (I) and a veterinarily acceptable formulation adjuvant for oral administration via the feed.

[0270] A specific composition is a "premix" that facilitates mixing of a uniform, relatively small amount of active ingredient (on a tonne basis) in / on the fish food.

[0271] Thus, one aspect of the present invention is a premix comprising nutrients, formulation supplements, and at least one compound of formula (I).

[0272] In one embodiment, the nutritional fish food is in the form of pellets that are mixed with or coated with a composition comprising one or more compounds of formula (I) as defined in claim 1. Such compositions may contain the compounds of formula (I) as a solution or in a specific form.

[0273] Another aspect of the present invention is a medicated fish feed comprising the composition or premix and a nutritional fish feed. Such feeds are prepared by commercial feed mills according to veterinarian instructions or based on labeling and transported to fish farms. Alternatively, such medicated feeds are prepared on the fish farm.

[0274] In one embodiment, the medicated fish bait is administered daily for a period of 3 to 14 days.

[0275] In one embodiment of the present invention, the compound of formula (I) or a salt thereof is orally administered at a daily dose of 1 to 10 mg / kg of fish organism, preferably 3 to 7 mg / kg of fish organism and most preferably at a daily dose of about 5 mg / kg of fish organism.

[0276] In one embodiment, the total treatment period for which the compound of formula (I) or a salt thereof is administered is 3 to 14 days (about 2 weeks), in one embodiment 3 to 7 days, in another embodiment 5 to 14 days, in another embodiment 5 to 10 days (about 1.5 weeks), and preferably 7 days. During the total treatment period, the compound of formula (I) or a salt thereof may be administered, for example, every day or once every two days. Preferably, it is administered daily. In a preferred embodiment, administration is daily for 7 days.

[0277] In a preferred embodiment, the compound of formula (I) or a salt thereof is orally administered at a daily dose of 1-10 mg / kg of fish organism weight for 3-14 days (about 2 weeks). In another preferred embodiment, the compound of formula (I) or a salt thereof is orally administered at a daily dose of 3-7 mg / kg of fish organism weight for 5-10 days. In a more preferred embodiment, the compound of formula (I) or a salt thereof is orally administered at a daily dose of about 5 mg / kg of fish organism weight for 7 days.

[0278] It should be understood that the amount of compound administered to fish to achieve the desired effect can vary due to the advantageous non-toxic properties of the compound. In one embodiment, the compound is orally administered at about 0.005-5000 mg / kg, particularly 0.01-500 mg / kg (i.e., mg compound / kg fish body weight / day). Additionally, the compound can be administered at relatively high doses, such as 0.01 mg / kg, 0.1 mg / kg, 1 mg / kg, greater than (i.e., greater than) 10 mg / kg, or even greater than 100 mg / kg. The duration of administration can be from a few hours or days up to several years.

[0279] Thus, oral administration involves administering to a population of fish a medicated fish food containing a compound of formula (I). The fish food is generally in the form of granules or pellets. Common ingredients of such fish food granules or pellets include fish meal, fish oil, vegetable protein, sugars and polysaccharides (including mannan, glucan and alginate). Additionally, excipients such as pigments, vitamins, minerals and binders may also be included.

[0280] The compound of formula (I) or its salt may be incorporated into the feed prior to pelleting, or alternatively, the compound of formula (I) or its salt may be coated onto granules or pellets, either per se or in the form of a premix, which may contain, in addition to the active compound, one or more veterinarily acceptable excipients, such as starch, fumed silica, microcrystalline cellulose, lactose, and preservatives.

[0281] The compound may be incorporated into the feed mixture before pelleting. However, it is preferred to coat pellets or granules with the compound of formula (I). For example, commercially available fish pellets or granules are coated with the compound of formula (I) using a solution in a veterinarily acceptable solvent, or alternatively, suspended in a carrier or with a premix containing the compound of formula (I) and one or more veterinarily acceptable excipients, such as starch, fumed silica (Aerosil®), microcrystalline cellulose, lactose, etc. Additionally, typical preservatives may be present.

[0282] The concentration of the compound of formula (I) in the premix may be chosen within wide limits; for example, concentrations of the compound of formula (I) of 0.001 to 90% w / w, preferably 1 to 50% w / w and more preferably 5 to 15% w / w, according to further embodiments 0.001 to 10% w / w, preferably 0.05 to 5% w / w and in particular 0.15 to 2.5% w / w, based in each case on the total weight of the premix, have proven useful.

[0283] The feed pellets can be coated with the premix by a dry top-coating method. For this purpose, the premix is ​​added to the pellets, and the resulting mixture is stirred / mixed to distribute the compound of formula (I) evenly on the pellets. According to an alternative top-coating method with further oil treatment, fish or vegetable oil is added to the product of the above dry top-coating method with continuous mixing until the pellets are completely coated. According to yet another embodiment, called a vacuum coating method, the premix is ​​first dissolved / suspended in fish or vegetable oil before being sprayed onto the pellets under vacuum. A solution is preferred.

[0284] After addition of the active ingredient to the fish feed, the pellets or granules contain, for example, about 0.0005 to about 5% (w / w), preferably about 0.001 to about 2.5% (w / w) and in particular about 0.0025 to about 1.25% (w / w) of a compound of formula (I), based on the total weight of the fish feed.

[0285] In one embodiment of the present invention, the amount of the compound of formula (I) or a salt thereof present in the fish feed premix composition is about 5 to about 20% (w / w), preferably about 10 to about 15% (w / w), and most preferably about 12.5% ​​(w / w), in each case based on the total weight of the premix.

[0286] combination The compounds and compositions may also be used in combination with one or more other physiologically active agents.

[0287] Thus, in one embodiment, the compound is co-administered with an additional physiologically active agent. Such combinations are selected based on the condition to be treated, the cross-reactivity of the components, and the pharmacological properties of the combination. For example, multifunctional agents, such as multivalent vaccines, are preferred in the treatment of fish, and therefore the composition may be administered with an antigen targeting a bacterial or viral disease. In one embodiment, the compound of formula (I) is co-administered with one or more antigens, and optionally, the compound and antigen are administered together with an adjuvant.

[0288] These compounds and compositions may be administered together or in the same course of treatment as the compounds and compositions described herein. By concomitant administration is meant that the individual components of the combination may be administered either sequentially or simultaneously in separate or combined veterinary compositions.

[0289] While administration of a compound of formula (I) generally provides only long-term control of body lice infestations, said control may in certain circumstances be further improved by use of a compound of formula (I) in combination with another physiologically active agent.

[0290] Such physiologically active agents may be either another antiparasitic agent, particularly a fish lice control agent; a vaccine component comprising an antibiotic or an immunostimulant; or a bait component containing an immunomodulator.

[0291] Such combination treatment may be required where the fish are already infected with mature parasites prior to treatment with a compound of formula (I) or where rapid elimination of the parasite is desired.

[0292] Thus, in one embodiment, the compound of formula (I) is co-administered with at least one additional physiologically active agent.

[0293] Suitable antiparasitic agents are, for example, hydrogen peroxide; formaldehyde; organophosphates such as trichlorfon, malathion, dichlorvos or azamethiphos; macrocyclic lactones such as ivermectin, emamectin benzoate or moxidectin; pyrethroids such as cypermethrin or deltamethrin; neonicotinoids such as imidacloprid, nitenpyram, thiamethoxam or thiacloprid; spinosyns such as spinosad; IGRs such as epofenonane, triplen, methopren or lufenuron or carbamates such as fenoxycarb.

[0294] When the compounds of formula (I) are used in combination with another compound active in controlling fish lice, said combination partner is preferably an organophosphate, a pyrethroid such as cypermethrin or deltamethrin, a macrocyclic lactone such as emamectin benzoate; hydrogen peroxide; or a neonicotinoid such as imidacloprid or thiacloprid.

[0295] In another embodiment, the combination partner is one or more isoxazoline compounds known in the art. Isoxazoline active agents are highly effective against a variety of ectoparasites, and their combination with a compound of formula (I) extends the spectrum of efficacy against these parasites. Particularly useful isoxazoline active agents that can be combined with the compound include afoxolaner (including a substantially pure active enantiomer), sarolaner, fluralaner (including a substantially pure active enantiomer), and lotilaner.

[0296] These active agents are described in U.S. Pat. No. 7,964,204, U.S. Pat. Appl. Pub. No. 2010 / 0254960A1, U.S. Pat. Appl. Pub. No. 2011 / 0159107, U.S. Pat. Appl. Pub.

[0297] Another combination partner is 2-chloro-N-(1-cyanocyclopropyl)-5-[1-[2-methyl-5-(1,1,2,2,2-pentafluoroethyl)-4-(trifluoromethyl)pyrazol-3-yl]pyrazol-4-yl]benzamide (CAS RN 1621436). This compound is known as tigolaner.

[0298] For example, a suitable combination treatment of the compound of formula (I) and another fish lice control agent can be carried out by first treating fish, particularly salmon, with the compound of formula (I) according to the feeding method and regimen described above, and then, for example, 3 months, preferably 5 months, more preferably 6 months and particularly 9 months after the end of the feeding treatment with the compound of formula (I), treating with another fish lice control agent; said second treatment can be topical administration, such as medicated bath treatment, or oral administration, such as feeding treatment, or preferably treatment by injecting the additional fish lice control agent into fish. According to a preferred embodiment of this combination treatment, feeding treatment with the compound of formula (I) is carried out at the end of the freshwater period of salmon evolution or the beginning of their seawater period.

[0299] The further combined treatment comprises first treating the fish, particularly salmon, with the further fish lice control agent, followed, for example, 1 hour to 2 months, preferably 1 hour to 1 month, or especially 1 week to 1 month later, by feeding the compound of formula (I) according to the present invention as described above. According to a preferred embodiment of this combined treatment, the treatment with the further fish lice control agent is a medicated bath treatment, feeding treatment, or injection treatment, which is carried out at the beginning of the seawater season, for example, 1 hour to 3 months, preferably 6 hours to 2 months.

[0300] According to a further embodiment of the present invention, feed treatment with a compound of formula (I) is combined with vaccination of fish against typical bacterial or viral infections. Typical bacterial diseases to be treated by vaccination include, for example, vibriosis, furunculosis, wound disease, atypical Aeromonas salmonicida, pisirickettsiosis, or ERM / yersiniosis. Examples of viral diseases to be treated include pancreatic disease / PDV, infectious pancreatic necrosis / IPNV, or infectious salmon anemia / ISAV. The vaccine is generally applied by bath or feed treatment, or preferably by injection. Vaccination can be carried out either immediately before, during, or after feed treatment of the fish with a compound of formula (I).

[0301] According to this embodiment of the combination treatment, the first treatment is a bath treatment with the compound of formula (I), followed by a feed treatment with hexaflumuron or lufenuron, the compound of formula (I), or emamectin, which may provide continuous protection against body lice. According to another embodiment of the combination treatment, the first treatment is a feed treatment with hexaflumuron or lufenuron, the compound of formula (I), or emamectin, which may provide continuous protection against body lice, followed by a bath treatment with the compound of formula (I).

[0302] In another embodiment, the compound of formula (I) is administered in combination with vitamins to improve the health of the animal.

[0303] There is abundant evidence worldwide of resistance in fish lice to chemotherapy drugs.

[0304] Surprisingly, compounds of formula (I) have been found to be effective in controlling sea lice populations that have been identified as resistant to commercially available sea lice chemotherapeutic drugs from the organophosphate class, macrocyclic lactones, particularly avermectins and pyrethroids, as indicated in the examples by ***.

[0305] The term "resistance," as used herein, refers to a reduced efficacy of a compound compared to untreated parasites, particularly body lice. The first appearance of this phenomenon was reported in Norway, where tolerance to organophosphates, particularly azamethiphos, increased to the point of complete loss of their efficacy by the mid-1990s. Treatment failures associated with pyrethroids were subsequently reported in Norway, Scotland, and Ireland. Subsequent bioassay-based analyses confirmed a reduced susceptibility to deltamethrin and cypermethrin. Recent bioassay-based testing confirmed the low susceptibility of C. rogercresseyi to pyrethroids. Therefore, it is particularly important to have available new, effective compounds that can effectively control such resistant parasite populations.

[0306] Thus, in one embodiment, fish lice infestations with parasites that exhibit resistance to macrocyclic lactones, organophosphates and / or pyrethroids are controlled, where the fish lice have been found to be resistant to macrocyclic lactones, organophosphates and / or pyrethroid antiparasitic agents, hi one embodiment, such fish lice populations are resistant to one or more of emamectin, deltamethrin or organophosphates.

[0307] kit Another aspect of the invention is a kit comprising a compound of formula (I) or a composition as described above containing such a compound, and instructions for administering the composition to fish.

[0308] In one embodiment, the kit comprises instructions for the preparation of a premix and medicated fish bait as described above and / or instructions for the administration of the medicated fish bait to a fish population to control fish lice infestations as described in more detail above.

[0309] In another embodiment, the kit includes instructions for preparing the preservative solution and medicated water for medicated bath treatment as described above and / or instructions for immersing fish to control fish lice infestation as described in more detail above.

[0310] Example The following compounds were prepared: The compounds were synthesized according to the methods described in WO 2016168059 and WO 2018073127. [ka]

[0351] Example 3: Adult Caligus rogercresseyi fish louse contact assay Motile stages of sea lice (i.e., Caligus rogercresseyi (pre-adults)) were exposed to seawater spiked with decreasing concentrations of test compounds (dissolved in PEG-seawater mixtures). After approximately 24 and 48 hours of continuous exposure, sea lice inhibition (% of dead + injured sea lice) was assessed compared to negative (vehicle) and untreated controls.

[0352] Results: EC of compound 1097 50 was 0.072 ppb after 24 hours and 0.035 ppb after 48 hours.

[0353] Example 4: Body lice resistance assay A fish lice resistance assay was performed using motile fish lice stages (i.e., preadults and adults) of several Lepeophtheirus salmonis isolates with known resistance profiles (i.e., fully susceptible, resistant to azamethiphos (OP), emamectin benzoate (ML), and deltamethrin (SP)). Fish lice were exposed to seawater spiked with decreasing concentrations of the test compound (dissolved in PEG300 / seawater mixtures). Fish lice inhibition (% of dead + injured fish lice) was assessed after approximately 24 and 48 hours of continuous exposure, compared to a negative (solvent) control.

[0354] Results: Compound 1097 inhibited susceptible isolates (EC 50 after 24 hours) and multiresistant isolates (EC 50 was equally effective against 1.96 ppb after 48 hours and 0.64 ppb after 48 hours.

[0355] Salmon against fish lice - in vivo efficacy Example 5: Efficacy testing using gavage Salmon (Salmo salar) were treated with a single oral gavage at a dose of 5 mg / kg body weight / fish (day 0). The formulation was 5% DMSO / 95% fish oil. A negative control group of salmon received only the formulation vehicle.

[0356] Fish were infected with Lepeophtheirus salmonis copepodids twice before treatment (i.e., around days -28 and -3) and once after treatment (i.e., day 17).

[0357] On day 7, fish were examined under sedation and (pre)adult fish lice on each fish were counted and removed (treatment efficacy against (pre)adult fish lice from day -28 infestation).

[0358] On or around day 28 (end of animal stage), fish were euthanized and the lice on each fish were classified (pre-adult or juvenile) and counted. The number of pre-adult and juvenile parasite stages corresponding to each infection time point was used to calculate efficacy, i.e., to assess the effectiveness of treatment of juvenile fish lice from infection on day -3 and to assess the effectiveness of prevention from reinfection on day 17.

[0359] Efficacy is expressed as the % reduction in body lice in the treated group relative to the control group using the Abbott formula.

[0360] Results: The therapeutic efficacy of the following compounds was ≥ 80% against (pre)adult fish lice: (* indicates 100% effectiveness) 1039, 1041*, 1042*, 1087, 1092, 1094, 1097*, 1099, 1100*, 1366*, 1367, 1368, 1370*, 1371*, 1372*, 1376*, 1378*, 1380, 1392*, 1393*, 1394*.

[0361] The following compounds had therapeutic efficacy of ≥80% against juvenile fish lice: (* indicates 100% effectiveness) 1039, 1041*, 1042*, 1092, 1099*, 1100*, 1366*, 1367*, 1368*, 1370*, 1371*, 1372*, 1376*, 1378*, 1380, 1392, 1393, 1394*.

[0362] The following compounds had preventive efficacy of ≥80% at reinfection on day 17: (* indicates 100% effectiveness) 1097*, 1367, 1370, 1378*.

[0363] Example 6: Efficacy test using dietary administration Four test groups of fish were used (one group for evaluation of therapeutic efficacy, one group for evaluation of preventive efficacy, and their respective controls). Commercially available fish feed pellets were coated with the formulated test compounds. The formulation used was 5% DMSO / 95% fish oil. Salmon (Salmo salar) were orally treated with 1 mg / kg fish biomass via the coated feed for seven consecutive days. The negative control group of salmon received only feed coated with the formulation vehicle.

[0364] Fish in the treatment group were infected with Lepeophtheirus salmonis copepods twice (around day -28 and -3) before treatment.

[0365] On or around day 8, fish were examined under sedation and the (pre)adult fish lice on each fish were counted and removed (assessment of treatment efficacy against (pre)adult fish lice from infection on or around day -28).

[0366] Around day 25, the fish were euthanized and the (pre)adult fish lice counted on each fish (assessment of treatment efficacy against juvenile fish lice from around day -3 infestation).

[0367] At two-week intervals, fish from the prophylactic group were infected at several time points after treatment.

[0368] Approximately 3 weeks after each reinfestation, the fish were assessed for (pre)adult fish lice. At each assessment, all (pre)adult fish lice were removed from the fish.

[0369] The number of fish lice on the fish corresponding to each reinfection time point was used to calculate the preventative efficacy.

[0370] Efficacy is expressed as the % reduction in body lice in the treatment group relative to the control group using the Abbott formula.

[0371] Results: Compound 1097 showed 100% efficacy against (pre)adult and juvenile fish lice. A therapeutic effect was achieved. The preventive effect against reinfection after treatment was 100% (D14). 99.9% (D28) and 86.0% (D42). The inventions described in the original claims of this application are set forth below.
