Description

[0001] NON-PHARMACEUTICAL SOLUTIONS AND USE THEREOF FOR

[0002] TRANSDERMAL DELIEVRY OF ACTIVE AGENTS

[0003]

[0001] TECHNICAL FIELD

[0004]

[0002] This application relates to a non-pharmaceutical solution intended to be used by a pharmacist or pharmaceutist to solubilize an active agent, such as a pharmaceutical agent or a biological agent and methods for preparing the non-pharmaceutical solution. In addition, this application relates to a method of using the non-pharmaceutical solution for transdermal deliver}' of the active agent to a patient in need thereof.

[0005]

[0003] BACKGROUND OF THE INVENTION

[0006]

[0004] Transdermal drug delivery', delivery' of drugs through the skin, provides many advantages. Primarily, it is a comfortable, convenient, and non-invasive way of administering drugs. Drugs delivered transdermally directly enter subdermal blood vessels and are transported to the target site via by-passing the first-pass liver metabolism and decomposition. As such, it allows for high drug bioavailability. Moreover, such a means of delivery' provides uninterrupted therapy and a higher degree of control over drug concentrations in the blood. These characteristics help avoid side effects caused by temporarily high blood concentrations of drugs which accompany administration of oral dosage forms and injections.

[0007]

[0005] In addition, as the population ages and health and end-of-life care evolves, the ability to formulate individualized products in small quantities to physician order has become more needful. Transdermal, transmucosal (Nasal & rectal) and oral suspension delivery is being increasingly utilized for formulation.

[0008]

[0006] Compounded transdermal formulations are typically extremely limited in their applicability due to the ordinary limitations of forming uncontrolled solutions / suspensions without regard to the dielectric parameters necessary' to accomplish bolus delivery of medicaments.

[0009]

[0007] A system that lends itself readily to the rapid formulation of less-than-1 -liter batches would be widely applicable to the practice of individualized medicine compounded per patient by physician order. Speed of production via utilization of pre-formulated transdermal vehicle, manufactured to cGMP standards can enable safer, more reliable individualized formulation outcomes.

[0008] Additionally, the process of drug development as practiced in the developed world is a time-consuming and painstaking process. Much of the effort is aimed at determining not only the efficacy of various dose concentrations but the interaction between the dose form and tissues of the medicated body. With any form of delivery, a unique set of challenges present A system, which safety and efficacy was previously established, and which could be reliably produced to current Good Pharmaceutical Manufacturing Practice (cGMP) could readily enable formulation of an active ingredient into a measurable, readily dispensable drug product.

[0010]

[0009] There remains a long felt need for a better means of transdermal delivery of active pharmaceutical or biological agent(s) to patients in need thereof in addition to compounding transdermal formulations comprising therapeutically effective amount of- pharmaceutical or biological agents.

[0096]

[0098] The present application relates to non-pharmaceutical solutions and methods of use thereof. Specifically, the present application relates to a non-pharmaceutical solution or solutions intended to be used by a pharmacist or pharmaceutist to solubilize an active agent to produce a pharmaceutical composition, of known concentration, capable of metered transdermal drug deliver}'. The pharmaceutical composition has specific dielectric properties that facilitate administration of a dissolved pharmaceutical agent across the skin. The composition may also be designed for transdermal delivery' of an active biologic ingredient. The composition can be manufactured in large volumes for batch application or provided in a bulk container. After application it cannot be reused.

[0097]

[0099] The practice of compounding pharmacy is well-used to mixing small batches of liquid and semi-solid dose forms for oral, spray-on or perianal purposes. These pharmacists serve specialty populations such as hospice, pediatric, frail elderly, and end-stage renal disease. Increasingly, physicians are prescribing compounded preparations at patient request when there is no viable commercially manufactured remedy fitting that patient’s needs. The process for weighing, measuring, and mixing an active pharmaceutical ingredient (API) into such preparations can be time-consuming and costly. These non-pharmaceutical solutions described herein can be prepared to cGMP quality, packaged in small units such as 500 milliliters or 1 liter and can be provided to a pharmacist or a pharmaceutist for preparation and dispensing to prescription order of a pharmaceutical composition. The inventors of the instant application found that batches of various pharmaceutical composition prepared using the non-pharmaceutical solutions described herein as a base can be built much more rapidly than traditional compounded remedies.

[0098]

[0100] The instant application discloses a non-pharmaceutical solution comprising one or more ingredients selected from the group consisting of two or more solvents, at least one solvent modifier, at least one solute modifier, at least one source of cellular activation energy, at least one skin stabilizer, and a mixture thereof.

[0101] In one example, the two or more solvents are selected from the group consisting of ethanol, ethylene glycol, propylene glycol, propylene carbonate, butylene glycol, acetone, glycerol, water, and a mixture thereof.

[0100]

[0102] Solvents

[0101]

[0103] The solvent is the principal component of the carrier for the active agent and, preferably, is one in which the active agent is soluble or at least substantially soluble or can be made soluble or become more soluble, by addition of one or more additional solvents or solvent-modifying agents. As used herein, by “substantially soluble” is meant that the minimum effective dose of the active agent, generally at least about 0.25 mg, preferably at least about 0.5 mg, especially preferably about 1 mg, or more, will dissolve in 1 cc of the solvents) or in 1 cc of a mixture of the solvents) with solvent modifying agem(s). Suitable solvents may be selected from any of the solvents normally used for medicaments, cosmetics, nutrients or other active agents to be delivered transdermally.

[0102]

[0104] Preferred solvents include lower alcohols of from about 2 to about 6 carbon atoms, preferably from 2 to 4 carbon atoms and may be monoalcohols, such as, for example, ethanol, isopropanol, sec-butanol, or polyols, such as, for example, ethylene glycol, propylene glycol, butylene glycol, glycerol. Mixtures of solvents may be used. Other solvents, such as ketones, e g., acetone, methylethyl ketone, ethers, e.g., ethyl ether, may also be used, in amounts which will be safe and non-toxic in use.

[0103]

[0105] While the non-pharmaceutical solution is generally non-aqueous, water may be used for water- soluble active agents and for those drugs or other active agents which are stable in the presence of and not denigrated by the presence of water. Water may also be introduced as a. component of one of the other ingredients, for example, as an alcohol: water azeotrope, etc When water is present in the solvent it will usually constitute less than about 50 percent, preferably less than about. 10 percent, especially, preferably, less than about 2 percent, by weight of the total solvent although more or less may be used depending on the active agent and so long as the objectives of the invention can be met. Furthermore, as will become apparent by the examples to follow, the compositions of this invention and utilizing the principles which will be described in more detail, hereinafter, may also be formulated as aqueous emulsions, including wherein the aqueous phase is the major and continuous phase. Such aqueous emulsions, as is the case with non-aqueous (usually less than about 5%, especially less than about 2%, of wa ter) non-nhatrnaceutical solution, will be rapidly absorbed by and relea se the active agent or agents in, typically, less than one minute.

[0121]

[0114] Solvent modifiers

[0122] [115 J A solvent modifier is selected to modify the polarity of the non -pharmaceutical solution to balance that of the active ingredient (solute). Therefore, solvent modifiers will usually be polar compounds (i.e. form polar ions in solution) and will usually contain a functional group containing oxygen, sulfur or nitrogen in its molecular form. Also, if the active agent is unsaturated the solvent modifier will usually also contain double bonds in the straight-chain or cyclic portion to match the structure of the solute (i.e., active agent). Most importantly, the solvent modifier or mixture of solvent modifiers enables the solvents) and solvent modifiers) to form a weak complex with the active agent, i e., an association via van der Waals forces and / or hydrogen bonding, thus yielding a stable pharmaceutical composition with a high solute / solvent ratio. As used herein, “stable” is intended to have its normal and usual meaning, namely, that the pharmaceutical composition may be stored at room or elevated temperature for one or more days, usually 30 or more days, without undergoing phase separation. By ‘‘high sok.de / solvent’ ratio is meant at least 0.25 mg solute per cubic centimeter of solvent (or solvent plus modifying agents) and, more generally, often amounts of solute exceeding the solubility of the solute in the solvent alone, or in each solvent of a multi-solvent system.

[0123]

[0116] As noted above, solvent modifiers may be individually (or as a group) selected from substances having structural elements in common with the active agent. However, it has been found that for many bio-active compounds and other active agents, a relatively small group of solvent modifiers can facilitate the dissolution of the active agent and formation of the weak association which enable the complex of active agent-modifier to pass the defenses of the skin with minimal irritation without modification of the chemical structure or stereoscopic configuration of the active agent.

[0124]

[0117] Thus, particularly favorable results have been obtained by using as the solvent modifier one or more of lemon oil (or / and d-limonene), Vitamin E, Pro-Vitamin B, Vitamin B\ D-panthenol and methylsulfonylmethane (MSM).

[0125]

[0118] The amount of solvent modifier will be selected to result in the desired solute / sol vent ratio, and will depend on various factors, including, for example, primarily, the polarities, and polarizabilities, dipole moments, van tier Waals forces of each component, including the solvent, solvent modifier, and solute (i.e., active agent).

[0126]

[0119] In this regard, in order to match the polarities, dipole moments, of the solute to that of the solvent system the amount of the individual components of the solvent system will be selected such that the weighted (molar) average of the dipole moments of the individual components will be substantially the same as the dipole moment of the solute in solution.

[0127]

[0120] The amount of solvent modifier(s) to achieve the desired sol ute / soi vent ratio ranges from about 0.0001 to about 50% (wt / wt), preferably, from about 0.1 to about 35%, more preferably, from about 0,1 to about 5% (wt / wt), based on the total solution.

[0128]

[0121] Solute modifiers

[0129]

[0122] The solute modifier may be included in the non-pharmaceutical solution where necessary to facilitate dissolution of insoluble or sparingly soluble solutes at higher concentrations. Solute modifiers which form reversible or temporary complexes with the solute to facilitate passage through the skin while minimizing immunological response are especially effective. The solute modifier will also, optimally, be a nutritional compound which will be metabolized by the body once the solute is released from the complex.

[0130]

[0123] Examples of solute modifiers include, but are not limited to, terpenes, polyphenolic flavinoids, and other sugar adduct glucoimndes, sterols, such as, for example, cholesterol and cholesterol-like compounds and hormones, such as isoflavones, 3,3'- tmodi propionic acid (sulfurated propionic acid), phosphatidyl serine and choline, Vitamin Ds, Vitamin Ki, dehydroepi andosterone (DHEA) and water. Another group of solute modifiers include bosweiiic acid, hypericum, phytic acid and water

[0131]

[0124] The amount of solute modifier can be about 0.003% (wt / wt), such as, for example, from about 0.003% (wt / wt) to about 5% (wt / wt) of the total amount of the nonpharmaceutical solution, preferably from about 0.1% (wt / wt) to about 5% (wt / wt) of the total weight of the non-pharmaceutical solution, more preferably from about 0 / 1. % (wt / wt) to about 4% (wt / wt) of the total weight of the non-pharmaceutical solution.

[0132]

[0125] Source of cellular activation energy

[0133]

[0126] The process by which transderm al drug delivery operates involves moving molecules across chemical and electrical gradients. Under ordinary tonic conditions, the introduction of materials through the skin results in chemical cascades that consume relatively large amounts of energy as the body seeks to defend itself against the challenge. Therefore, the non-pharmaceutical solution used for preparation of transdermal pharmaceutical composition as described herein, according to one preferred embodiment, includes a substance which brings stored energy or the stimulus for release of stored energy on a cellular level, thereby minimizing energy-negative reactions, which could lead to sensitization, ACD or anaphylaxis. The inclusion such a stored energy substance results in a multiplied net increase in available cellular energy- arid, accordingly, the potential acceleration of those reactions which result in the active agent ultimately reaching its target and being effectively utilized by the body.

[0134]

[0127] One example of a. source of cellular activation energy includes extracts of the plant Coleus Forskohlii, and especially, Forskolin, a labdane di terpenoid Other extracts of Coleus Forskohlii, such as, Colforsin or Coleonol, for example, can also be used.

[0135]

[0128] Other examples of cellular activation energy sources for stimulating generation of cAMP, either via. precursors or cellular activators, include, for example, methyl xanthines, Saikogenin and Saikosaponin, Angelicae dahuricae radix (yielding angelic acid), phellopterin, oxypeucedanin.

[0137]

[0130] The amount of the source of cellular acti vation energy can range from 0.001% to 0.1%, preferably, from about 0.001% (wt / wt) to about 0.01% (wt / wt) of the total weight of the non -pharmaceutical solution, more preferably, from about 0.001 % (wt / wt) to about 0.005% (wt / wt) of the total weight of the nou-pharmaceutical solution.

[0138]

[0131] Skin Stabilizers

[0139]

[0132] Skin stabilizers may be included in the non-pharmaceutical solutions described herein to stabilize the skin prior to passage and to assi st the skin to repair any damage resulting from the transmigration of the active agent and solvent and other components of the solution.

[0140]

[0133] Suitable skin stabilizers may provide one or more of the following attributes to facilitate safe and effective dosing of the active agent while avoiding local or systemic sensitization: form hydrogen bonds and complex with free radicals; act as a bridge for coHagen, keeping the strand intact temporarily during repair; stimulate the body's repair mechanisms, modulating prostaglandins, cytokines and die like, re-stabilize the Elastin complex after the composition passes through the skin, carry cationic potential, stimulating nerve transmission, i.e., decreasing nerve repolarization time at synapses. In addition, preferred skin stabilizers should be able to be metabolized by the body and should also shield a medicament or other active agent(s) from, the skin's defense mechanisms by forming suitable complexes which wi 11 be readily uncomplexed when the active agent reaches its intended site.

[0141]

[0134] Examples of substances which may function as skin stabilizers and which may be included in a son-pharmaceutical solution as described herein include glycerin monolaurate (e.g., as Lauricidin®) and similar fatty acid esters, Vitamin Ds, alkoxy glycerols, unsaturated fatty acids, such as, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and gamma-linolenic acid (GLA ), Vitamin E (alpha tocopherol) and the esters, e.g., acetate, and derivatives thereof, e.g., tocotrienoh D- pantnenol, phytantrioi, Dehydroepiandosterone (DHEA), pregnenolone, pregnenolone acetate, ascorbyl palmitate, and the like.

[0142]

[0135] The skin stabilizer can be present in an amount ranging from about 0.05% to about 5%, preferably, from about 0.1% (wt / wt) to about 5% (wt / wt) of the total weight of the non- pharmaceutical solution, more preferably, from about 0.1 % (wt / wt) to about 2% (wt / wt) of the total weight of the non-pharmaceutical solution It is preferred to select stabilizers which will be effective in stabilizing the skin at as low a concentration as possible.

[0143]

[0136] In one example, a non-pharmaceutical solution described herein comprises two or more solvents selected from ethanol, propylene glycol, propylene carbonate, acetone, and a mixture thereof.

[0144]

[0137] In another example, a non-pharmaceutical solution described herein further comprises one or more ingredients selected from the group consisting of lemon oil vitamin E, D- panthenoh Methyl sulphonyl methane, phytantrioi, glycerin monolaurate, forskolin, and a mixture thereof.

[0145]

[0138] In one preferred example, the non-pharmaceutical solution (herein referred to as NPS- A.) comprises ethanol in an amount of about 47% (wt / wt), propylene glycol in an amount of about 49% (wl / wt), acetone in an amount of about 3% (wl / wt), and one or more ingredients selected from the group consisting of at least one solvent modifier, at least one solute modifier, at least one source of cellular activation energy, at least one skin stabilizer, and a mixture thereof in an amount of 1% (wl / wt) of the total weight of the non -pharrn aceuti cal sol uti on .

[0146]

[0139] In another preferred example, the non-pharmaceutical solution (herein referred to as NPS-B) comprises ethanol in an amount of about 44% (wt / wt), propylene carbonate in an amount of about 50% (wt / wt), acetone in an amount of about 2% (wt / wt), and one or more ingredients selected from the group consisting of at least one solvent modifier, at least one solute modifier, at least one source of cellular activation energy, at least one skin stabilizer, and a mixture thereof in an amount of 4% (wt / wt) of the total weight of the non-pharmaceutical solution.

[0147]

[0140] Various non-pharmaceutical solutions for solubility experiments and pre-clinical and clinical batches were prepared. The inventors surprisingly found thatNPS-A and NPS- B and variations thereof can incorporate many active ingredients without further optimizing the solution, or with minimal additions of amounts of alternative solvents such as water, glycerol, or additional excipients. These variations are readily reproduceable at small scale and can be reduced to batching instructions.

[0148]

[0141] Non-Pharmaceutical Solution A (NPS-A):

[0149]

[0142] Non-Pharmaceutical Solution B: (NPS-B):

[0150]

[0143] Variations of the above two non-pharmaceutical solutions A and B are shown in Table

[0151]

[0144] Using preferred non-pharmaceutical solutions, experiments were conducted in animal models then in single patients then multiple patients and the analyzed results of the experiments unequivocally establish the ability of the non-pharmaceutical solutions described herein to deliver active agent(s) across intact skin and create a physiological reaction once in tissue in the subject.

[0152]

[0145] The instant application provides non-pharmaceutical solutions, to which upon adding an active agent, can quickly introduce an active agent through intact skin or mucous membrane or other viable membrane or external covering of animal, including humans, or plants, while minimizing damage and, therefore, minimizing the immune response of the skin or membrane to this introduction / challenge.

[0153]

[0146] Most active agents require a critical amount of the compound of interest to be introduced into the body of the patient all at once. This is referred to in the literature as the bolus dose effect. If this critical mass is not reached the medicament is ignored by physiology. The instant application provides non-pharmaceutical solutions, to which upon adding an active agent, can quickly introduce a bolus of medicament or other active agent through intact skin or mucous membrane or other viable membrane or external covering of animal, including human, or plant, engaging the body’s bolus response enabling many more medicaments to be dosed transdermally

[0154]

[0147] Rapid introduction of the active agent enables: (a) minimal immune response or anaphylaxis, and (b) repetitive dosing over the same area of skin over a short term or, if needed, for a longer course of therapy.

[0155]

[0148] It is understood that all ingredients used in the compositions of this invention must, within the applied and recommended dosages, be non-toxic and safe for animal and human use. Also, all amounts, parts and percentages in the following description and appended claims are on a weight basis unless otherwise noted.

In one aspect of the embodiment, the kit comprises instructions for preparing and / or applying a transdermal pharmaceutical composition as described herein.

[0172] Although not wishing to be bound by any particular theory of operation, it is behoved that the most adequate theory describing how the active agent (i.e., a pharmaceutical / biotogical agent) rinds its way, once inside the body, to the intended target site, is the so-called “information theory / '1This theory asserts that the active agent for which the body develops particular affinities when challenge is present due to degenerative disease, infection or trauma. The affected tissues selectively attract and bind these substances as they encounter them in humor or tissue mediums while normal tissues seek to deflect the compounds away. Once the carrier med icam ent-complex arrives in the vicimty of the diseased or “abnormal” tissue, the attraction of the tissue receptors overcomes the weak association between the non-pharmaceutical solution and the medicament and the medicament is released intact and taken by the needy tissue. By a similar mechanism modifying agent components may be stripped from the complex prior to arriving at the needy tissue.

[0173] [16T| Examples of active agents which may be incorporated in the non-pharmaceatical solutions are not particularly limited. Generally, any active agent previously used or suggested as useful for delivery by any means, including transdermaily, whether by patch or ointment or other topical formulation, may be used. Some areas where it is envisioned that the transdermal compositions will have particular benefits include pain relief (for safer dose of a prescription or n on-prescription analgesic locally to the site of pain); antibiotic delivery, e.g., Ciprofloxacin (permitting higher dosages at the locus of the infection to above safe systemic levels); corticosteroids (for treating inflammatory indications with delivery bypassing the liver and minimizing systemic side effects); hormone replacement therapy (e.g., to deliver tri-estrogens to the non- carcinogenic androgen pathway along with the inclusion of mechanisms to offset the negative cosmetic side effects of this pathway); isofiavinoid cancer therapies (allowing high concentrations); hypertoxic chemotherapies (io raise local concentrations with reduced impact systemically).

[0168] The embodiments also offer benefits in connection with active agents of high molecular weights for which prior known topical transdennal delivery systems were not effective or applicable. The transdermal pharmaceutical compositions described herein were found effective for active agents having molecular weights in excess of about 325 Daltons, especially higher than about 350 D, more especially higher than about 375 D and most especially higher than about 400 D, for example, 500 D and higher. Extremely high molecular weight substances such as calcitonin (MW-4500) human insulin (MW--6,000) and other hormones, polypeptides, and protein, may be solubilized in the non-pharmaceutical solutions described herein.

[0174]

[0169] The transdennal pharmaceutical compositions as described herein can be formulated to delivery, per unit dosage, usually about 1 cc, at least about 0.25 mg, especially at least about 0.5 mg, especially, up to about 1 mg or higher of active ingredient, including such high molecular weight substances as described above.

[0175]

[0170] The transdennal pharmaceutical compositions were developed in series and tested on in vitro constructs, a single animal, then several animals in controlled conditions measuring pharmacokinetics and subsequently, pharmacodynamics of several formulations. Safety of the compositions was tested in a standard accepted model for inducing irritation from topically applied products. The compositions were subsequently tested in a single patient, several patients and eventually many patients.

[0176]

[0171] The effective dosage of the active agents was observed to be substantially less than the effective dosage when administered orally or intravenously or intramuscularly. However, higher, or lower dosages may be required or advantageous depending on the condition or disease to be treated, whether intended for local or systemic administration, etc.

[0177]

[0172] EXAMPLE 1: TRANSDERMAL TESTOSTERONE FORMULATION

[0178]

[0173] Three lots of transdermal testosterone formulations were prepared by adding 50 mg of testosterone to 1 ml of NPS-A.

[0179]

[0174] One demo lot was placed on stability and monitored at the intended long-term storage condition (25 °C) and at the accelerated storage condition (40 °C). A limited photo stability study was conducted for 7 days.

[0180]

[0175] One development lot was placed on stability and monitored at the intended long-term storage condition (25 °C / 60%RH) and at the accelerated storage condition (40 °C / 75%RH).

[0181]

[0176] A third development lot was placed on stability and monitored at the intended longterm storage condition (25 °C / 60%RH) and at the accelerated storage condition (40 °C / 75%RH).

[0182]

[0177] The transdermal testosterone formulations from these 3 studies were stored in a single packaging configuration consisting of a 30 ml PE bottle with integral pump spray snap cap. Each 30 ml PE bottle contained 30 ml @ 50 mg / ml dosage.

[0183]

[0178] Stability data through a 6-month time point were analyzed.

[0184]

[0179] The drug product exhibited no significant decrease in purity. No adventitious impurities were detected. For all storage conditions, appearance and assay remained unchanged.

[0185]

[0180] Preclinical experiments showed an increase in serum concentration levels of testosterone between the zero-time point and 30 minutes. # of the 5 animals tested continued to show increased serum levels up to the 1-hour timepoint.

[0186]

[0181] Clinical Experiments

[0187]

[0182] Study treatment and design

[0188]

[0183] A single dose, open label, non-crossover study involving 5 healthy volunteers was conducted to study the transdermal testosterone formulation at five escalating doses of 10, 20, 30, 40, and 50 nigs dosed by means of 1-5 metered sprays. The subjects were randomized to one of the five doses stated above by computer-generated randomization.

[0189]

[0184] Five healthy male subjects successfully participated in this study according to the protocol. Of the 5 subjects enrolled In the study, three were Caucasian, and another two from other ethnics. The mean (SD) age of the subjects was 29.0 (6.2) years old, and the mean (SD) BMI was 24.1 (3.2) kg / m2. The study was approved by the East London and The City Health Authority Research Ethics Committee. All the subjects gave written informed consent before participated in the study. All the subjects were admitted to this study having fulfilled all entry criteria as outline in inclusion / exclusion criteria and the physical examination, medical history, and the clinical laboratory test.

[0190]

[0185] All 5 healthy subjects successfully completed the study according to the protocol. The concentrations of testosterone in serum were obtained from the calibration curve from the individual absorbance value.

[0191]

[0186] FIG. 2 show's the plot of mean serum concentrations of testosterone (ng / mL) versus time (h) from -0.5 to 24 hours post dose for five subjects for all the treatments given. The individual serum concentration plot shows the testosterone concentrations fluctuated in most of the subjects treated by the transdermal testosterone formulation.

[0192]

[0187] No serious or unexpected adverse events were reported or observed during the study day. The applied dosages and protocol requirements were well tolerated by all subjects.

[0193]

[0188] In conclusion, the transdermal testosterone formulation prepared according to the method described herein delivered testosterone systemically in humans and the concentrations of hormone in the first 12 hours following administration of the transdermal testosterone formulation were bioequivalent to an existing topical deliverygel.

[0194]

[0189] Further studies at a set comparable dose were engaged. A single dose, 3 crossover, 3 treatment 6 sequences comparative study was organized with one arm dosed with placebo, another arm dosed with AndroGel® 50 mg and a 50 dose of transdermal testosterone formulation prepared as described herein. Subjects were cannulized on test days and 17 4-mL blood samples taken and tested via ELISA. All subjects consistently showed higher response to the transdermal testosterone formulation prepared as described herein. FIG. 2 shows the net change from baseline.

[0195]

[0190] EXAMPLE 2: TRANSDERMAL LIDOCAINE FORMULATION

[0196]

[0191] This placebo controlled, double blind trial compared anaesthetic properties of two transdermal lidocaine formulations (prepared using NPS-A and NPS-B) with placebo. The active and placebo treatments were applied to the dorsum of the hands, bilaterally and simultaneously for 5 min on 100 healthy volunteers. Following cannulation, pain perception was measured using the verbal rating score (VRS) and visual analogue score (VAS). Lidocaine plasma levels were assessed at 0 and 2 h and the results are shown in FIG. 3A and FIG. 3B. The VRS and VAS results show that the transdermal formulation prepared using NPS-B significantly decreased pain score compared to placebo (p < 0.02). Blood lidocaine at 2 h post application was also higher for transdermal formulation prepared using NPS-B than for transdermal formulation prepared using NPS-A, suggesting that a 5 min application of transdermal formulation prepared using NPS-B was effective in delivering local anaesthetic and accelerating the onset of skin anesthesia prior to venous cannulation in adults.

[0197]

[0192] Study design and subjects

[0198]

[0193] This study was prospective, double blinded and placebo controlled, with a 1-week washout period, involving 100 healthy volunteers. Based on our previous study, 100 subjects recruited in this study would have an 80% power to detect a difference of 25% in the primary outcome measures at p < 0.05. Prior to enrolment, each subject was screened for standard blood biochemistry', drugs of abuse, and answered a questionnaire for demographics. Skin was assessed for erythema, edema, itching, broken skin, or other signs of pathology. Body mass, height, body mass index, systolic and diastolic blood pressure, and heart rate were recorded. Subjects outside the age range of 20- 40 years, with signs of skin pathology, hematology ‘out of standard limits’ or with positive drug abuse tests were excluded. Subjects were not permitted any form of analgesia within 1 week of the trial. The study was approved by the East London and City Authority Research Ethics Committee and received a Doctors and Dentists Exemption Certificate (DDX) from the MHRA (Medicines and Healthcare Products Regulatory Agency, LTK). Subjects were admitted to the investigation having been provided with a verbal and written explanation and signed a consent form.

[0199]

[0194] Admission and procedure

[0200]

[0195] Subjects were admitted to the Study Unit having fulfilled all the inclusion criteria. Blood pressure and heart rate were measured after subjects rested for 10 min. A sample was taken from an antecubital vein to establish a baseline measurement of plasma lidocaine concentration. All subjects were dosed according to the randomization schedule. In the Phase 1 study, the transdermal formulation prepared using NPS-B was applied to the dorsal surface of a randomly selected hand and NPS-B (placebo) was simultaneously applied on the contralateral hand. Administrations of the formulations were achieved by metered pump spray of 1 ml to the area of 4 cm2. Five minutes after application, the hands were routinely cleaned using alcohol wipes prior to venepuncture.

[0201]

[0196] A vein on each hand within the treatment area was then cannulated using a 20G butterfly needle. The success of cannulation was confirmed by the ability to withdraw 1-2 ml of blood. Two methods of pain assessment, Verbal Rating Score (VRS) and Verbal Analogue Score (VAS), were used to assess the pain of the procedure. Following successful bilateral cannulation, a VRS pain classification was used for each hand. The volunteers were asked the following question: 'How strong was the pain of the procedure?' and provided with a choice of five categories:

[0202] ® no pain

[0203] ® minimal sensation

[0204] ® mild pain

[0205] ® moderate n A ain

[0206] ® severe pain

[0207] The volunteer selected one answer for each hand by circling the number.

[0208]

[0197] In the VAS assessment, a 100 mm horizontal line with endpoints that are anchored by descriptors 'no pain’ and 'severe pain' was used. For each hand, the volunteer was asked 'What did the procedure feel like?' and then requested to make a vertical line on the horizontal line which represented the intensity or unpleasantness of their pain by the procedure. Values were measured in millimeters from the left-hand edge of the horizontal line.

[0209]

[0198] Two hours after the treatment application, another blood sample was taken to assess the systemic level of lidocaine. The plasma was transferred to cryo-vials and stored at 20 °C until analysis. All the procedures, including treatment applications, bilateral cannulation and data recording were each performed blindly by separate investigators. One week later, the volunteers repeated the above procedure with the transdermal formulation prepared using NPS-B.

[0210]

[0199] Analytical method

[0211]

[0200] Plasma concentration of lidocaine was analysed by using the liquid chromatographymass spectrometry (LC-MS / MS) method. Sample separation and detection was achieved on a Supel cosil LC-Si 10 cm column and PE SCIEX API 2000 mass spectrometer. The method was validated to demonstrate adequate sensitivity, specificity, accuracy and precision. The lower limit of quantification (LOQ) was 0.5 ng.ml and bupivacaine was used as an internal standard.

[0201] Statistical analysis

[0212]

[0202] All the data were analyzed using GraphPad Prism 4.0

[0213] (h ttp : Z / www . graph pad . com / pri sm / Pri sm . htm )an dMi ni tab 14 stati sti cal software

[0214] (http: / / www.minitab.com / ). The active treatments were compared to the placebo control using Wilcoxon’s Signed Rank test. The lidocaine concentrations at 2 h for transdermal formulations prepared using NPS-A and NPS-B were compared using Student’s paired t-test.

[0215]

[0203] Formulation Effectiveness

[0216]

[0204] One hundred healthy volunteers were successfully recruited, and the demographics data are presented in Table 1. Of the 100 subjects, 65 were Caucasian, 22 Asian, four African / Caribbean, and nine from other ethnic groups. The cannulation procedures were successfully completed at the first attempt for ah 100 volunteers. All the subjects tolerated the procedure well and complied with the study protocol.

[0217]

[0205] The median for VRS and VAS scores were different between active and placebo for both transdermal formulations prepared using NPS-A and NPS-B.

[0218]

[0206] The result from this exploratory' study showed that immediately following application of a transdermal lidocaine formulations prepared as described herein, there is a fast onset of effective anaesthesia for the venous cannulation in adults.

[0219]

[0207] In conclusion, topical application of the transdermal lidocaine formulations prepared as described herein was effective in providing skin anaesthesia for dorsal hand vein cannulation in healthy subjects, after 5 min of application.

[0242]

[0229] EXAMPLE 15: TRANSDERMAL INSULIN FORMULATION

[0243]

[0230] In another Pharmacokinetic and pharmacodynamic study, the time course dose response effects of the application of transdermal human insulin formulations prepared according to a method described herein on fasted blood glucose, and the corresponding levels of human insulin in the plasma of control male was investigated Wistar rats, and STZ induced Type 1 diabetic rats. A low-dose range was used for non-diabetic control animals and an appropriate larger dose for diabetic animals was employed.

[0244]

[0231] It was observed that the transdermal application of low7doses of human insulin did not induce a decrease of fasted blood glucose in control animals. As is normally the case, normal animals compensated for the increase in serum insulin by decrease in blood glucose by the release of hepatic glucose. In the normoglycemic condition in healthy animals and humans, insulin treatment induces the release of glucagon and epinephrine and consequently the release of glucose by the liver. However, in diabetic rats, treatment with transdermal human insulin formulation resulted in a significant drop in fasted blood glucose levels, particularly in animals treated with 4 lU / kg / ml.

[0245]

[0232] In order to confirm the presence of active potent Human insulin in both model s, diabetic and non-diabetic animals, Serum samples were analyzed by ELISA and Human insulin was detected as early as 5 minutes after the transdermal application with a maximum observed concentration at 30 to 60 minutes later and then was observed to decrease afterwards during the study time course.

[0246]

[0233] FIG. 24A shows mean of the human insulin levels measured in the plasma of non- diabetic rats during the time course of the kinetic study after treatment with placebo (1 ml / kg), or insulin solutions (0.4 lU / kg and 0.8 lU / Kg).

[0247]

[0234] FIG. 24B shows mean of the human insulin levels measured in the plasma of diabetic rats during the time course of the kinetic study after treatment with placebo (1 ml / kg), or insulin solutions (0.4 lU / kg and 0.8 lU / Kg).

[0248]

[0235] The data confirms that the non-pharmaceutical solution described herein acts as a vector or carrier permitting human insulin to cross the animals’ skin barrier and to stimulate physiological activity in a dose dependent manner, reducing blood glucose levels, in an animal model of type 1 diabetes.
