Abstract
Description
Prior technology
[0001] The complement system refers to a group of proteins involved in the innate immune system. This aids or complements the ability of antibodies and phagocytes to clear pathogens from an organism. There are three cascades involved in this system, namely the classical pathway, the lectin pathway and the alternative pathway. The cascades are triggered by different recognition events and lead to the recruitment and activation of a series of proteins capable of tagging the cell surface and amplifying processes that can lead to cell lysis, damage or engulfment.
[0002] The classical pathway is activated by binding of the complement protein C1q either directly to the cell surface or to proteins that bind to the cell surface. In one of the main functions of the classical pathway, CIq can be recruited by antibodies specific for cell surface antigens. CIq is a large polyprotein of 460 kDa consisting of 18 polypeptide chains (6 CIq A chains, 6 CIq B chains and 6 CIq C chains). These chains form a larger symmetrical protein composed of three segments: a tail region, an arm region and a globular head region. The single tail segment is divided into six symmetrical arms, each of which terminates in a bulbous head. The majority of CIq circulating in the blood carries a heterotetrameric complex of the complement proteins CIr and CIs, two serine proteases that initially bind to CIq as inactive zymogens. This larger multi-chain assembly is called the C1-complex. Binding of the C1-complex to the cell surface or to the appropriate complement-fixing epitope of the recruited protein, such as that found in the Fc region of an antibody, induces a conformational change in a series of activation and amplification events. In response to binding, C1r is first activated, followed by cleavage and activation of C1s. Subsequently, complement C4 is recruited into the complex where it is incorporated and cleaved by C1s to C4b. This cleavage results in the exposure of a moiety that allows C4b to be covalently attached to the cell surface. Subsequently, this new complex recruits complement C2, which, in association with C4b, is cleaved from C1s to C2a. The surface-bound complex of C4b and C2a forms the C3-convertase that drives the subsequent cleavage of complement C3 and the surface-bound and activated downstream steps of the complement cascade. A single C1-complex is capable of constituting multiple C3-convertase modules on the surface, leading to a strong amplification of the original targeting event.
[0003] These events can cause tissue damage and cellular clearance / destruction in normal function as well as in disease pathology. It has also been found to play a key role in the pruning of synapses in normal neuronal development and in CNS disease pathology. These outcomes can be driven in various cases by the accumulation of C4 and C3 cleavage products on the surface, the progression of the cascade to the final step of membrane attack complex formation and / or pore-mediated lysis, and the presence of early complement stages. Accumulation of immune complexes of the combined components. In some cases, C1r and / or C1s expression can also be increased by local induction as part of a biological response, and the action of these proteases can further contribute to the development of disease pathology (see, e.g., Xavier et al. Am. J. Renal Physiol, 2019).
[0004] The complement system is a central component of innate immunity and serves as a bridge between innate and adaptive immune responses. However, it can also turn its destructive capabilities against the host cell. Aberrant activation or inadequate regulation of the complement cascade is involved in many diseases and pathological conditions. Accordingly, many neurodegenerative, inflammatory, and autoimmune diseases are believed to result from, or at least substantially be driven by, bursting complement factor activity.
[0005] For example, the cognitive abilities of humans, and especially patients with neurodegenerative diseases, are highly dependent on synapse formation. The formation of precise neuronal circuits during development is a highly regulated and dynamic process. Excessive numbers of synapses are first generated to establish the initial wiring pattern of the brain, but the formation of mature and precise neuronal circuits requires the selective elimination and pruning of specific synapses. Neuronal activity plays an important role in this optimization phase, which exploits the targeting of early components of the classical complement cascade to achieve this elimination.
[0006] However, premature synapse loss in neurodegenerative pathologies results in loss of neuronal activity and aberrant activation of synaptic pruning, thereby leading to cognitive decline. In neurodegenerative diseases such as Alzheimer's disease and glaucoma, complement factors such as complement factor C1 and their subunits such as C1q are expressed in neurons where they act as Signaling in synaptic elimination. See, eg, US Patent Publication Nos. US 2012 / 0195880 and US 2012 / 0328601. In the adult brain, synapse loss often precedes pathology and clinical symptoms in many neurodegenerative diseases long before. Prompt therapeutic intervention to prevent or reduce synapse loss can slow or prevent the development of clinical symptoms of neurodegenerative diseases.
[0007] Accordingly, inhibition or modulation of classical complement activity has been identified as a promising therapeutic strategy. Therefore, there is a need to explore and develop methods for inhibiting or modulating the aberrant activities of these complement factors.

[0144] The phrase "parenteral administration / administered parenterally" as used herein means modes of administration, other than enteral and topical administration, usually by injection, and include, but are not limited to, intravenous, Intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcutaneous, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion Note. Pharmaceutical compositions suitable for parenteral administration comprise one or more active compounds and may contain antioxidants, buffers, bacteriostats, solutes to render the formulation isotonic to the blood of the intended recipient, or suspending agents or thickeners. One or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions or sterile powders which can be reconstituted into sterile injectable solutions or dispersions immediately before use.
[0145] Examples of suitable aqueous and non-aqueous carriers that can be used in the pharmaceutical compositions of the present invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like) and suitable mixtures thereof, Vegetable oils such as olive oil and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by using coating materials such as lecithin, by maintaining the required particle size in the case of dispersions and by using surfactants.
[0146] These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents including, for example, parabens, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like in the compositions. Additionally, prolonged absorption of the injectable pharmaceutical form is brought about by the inclusion of absorption delaying agents such as aluminum monostearate and gelatin.
[0147] In some instances, slowing the absorption of drugs injected subcutaneously or intramuscularly may be desirable in order to prolong the effect of the drug. This can be achieved by using liquid suspensions of crystalline or amorphous materials with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
[0148] Injectable depot forms are made by forming microencapsule matrices of the compounds of the invention in biodegradable polymers such as polylactide-polyglycolide. The rate of drug release can be controlled by the ratio of drug to polymer and the nature of the particular polymer employed. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
[0149] For use in the method of the present invention, the active compound may be used by itself or in a pharmaceutical composition containing, for example, 0.1% to 99.5% (more preferably 0.5% to 90%) of the active ingredient and a pharmaceutically acceptable carrier form given.
[0150] Introduction methods may also be provided by refillable or biodegradable devices. In recent years, various slow release polymeric devices have been developed and tested in vivo for the controlled delivery of drugs including protein biopharmaceuticals. A variety of biocompatible polymers, including biodegradable and non-biodegradable polymers, including hydrogels, can be used to form implants for sustained release of compounds at specific target sites.

[0152] The selected dosage level will depend on various factors including the activity of the particular compound or combination of compounds employed, or its ester, salt or amide; the route of administration; the time of administration; Excretion rate of multiple specific compounds; duration of treatment; other drugs, compounds and / or materials used in combination with one or more specific compounds employed; age, sex, weight, condition, general health of patients treated and prior medical history; and similar factors well known in the medical arts.
[0153] A physician or veterinarian of ordinary skill in the art can readily determine and prescribe the therapeutically effective amount of the pharmaceutical composition required. For example, a physician or veterinarian can start dosages of the pharmaceutical composition or compound at levels lower than that required to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved. "Therapeutically effective amount" means a concentration of a compound sufficient to elicit the desired therapeutic effect. It is generally understood that an effective amount of a compound will vary according to the subject's weight, sex, age and medical history. Other factors affecting the effective amount can include, but are not limited to, the severity of the patient's condition, the disorder being treated, the stability of the compound, and, if desired, another type of therapeutic agent administered with the compound of the invention. Larger total doses can be delivered by multiple administrations of the agent. Methods for determining efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) Harrison's Principles of Internal Medicine 13th Ed., 1814-1882, which is incorporated herein by reference).
[0154] In general, a suitable daily dose of the active compound employed in the compositions and methods of this invention will be that amount of the compound which is the lowest dose effective to produce a therapeutic effect. Such effective dosage will generally depend on the factors described above.
[0155] If desired, the effective daily dose of active compound may be administered in unit dosage form as one, two, three, four, five, six or more sub-doses administered at appropriate intervals throughout the day, as appropriate. and.
