1 A Novel Topical Transdermal Delivery System Mark S. Nestor, M.D., Ph.D.DirectorCenter for Clinical and Cosmetic ResearchAventura Florida
2 Topical Drug and Cosmetic Delivery The skin is a formidable barrier against environmental assaults as well as topical drug deliveryA variety of active compounds have significant activity in the skin, subcutaneous tissue or muscle but cannot adequately permeate the intact skinDiseases such as acne, psoriasis, rosacea, and melasma as well as cutaneous aesthetic enhancement could dramatically benefit from our ability to better transport active compounds to target tissueSolutions to a 100+ billion dollar marketIonic Nano Particle Technology (InParT) is a novel and unique passive delivery system that can be utilized to assist the transport of a variety of active compounds to target sites in the skin and beyond
3 InParT Drug Delivery System Ionic Nano Particle Technology I Novel, commercially viable trans dermal non-invasive drug delivery technology that enables delivery and absorption of active compounds through the stratum corneum and throughout the skin and sub cutaneous tissue without any cutaneous toxicity
4 InParT Drug Delivery System Ionic Nano Particle Technology II Nano particles are made from combinations of micelles (surfactants and protein solubilizers), coated with lipid moleculesNano paticles size; less than 1-10 nano meters smaller than the skin poresNano Particles Physically entraps active without any changes in the chemical compositionStabilizes the actives: shelf stable at room temperature for extended period of time without refrigeration)Uses all FDA approved ingredients
5 InParT Drug Delivery System Ionic Nano Particle Technology III INParT technology is highly adaptable to most high molecular weight drugs, proteins, peptides and insoluble hydrophobic moleculesCapable of delivering more than one therapeutic agent at a timeOffers high market value by featuring maximum functionality at minimum system complexity and costThe technology is easily scalable to any size without any complex new equipments need (no capital expenditure, commercially viable)

10 InParT Drug Delivery System Topical Hyaluronic Acid (HA) HA crosslinked or non crosslinked difficult to adequately penetrate the stratum corneumIf adequate penetration can be achieved topical cross linked HA can significantly improve fine lines as well as skin texturePainless applicationCompanion treatment to injectable crosslinked HATopical cosmecutical
11 Topical Hyaluronic Acid (HA) Clinical Model The stabilized cream is applied topically onto the skin containing crosslinked (non crosslinked) HAThe nano-spheres helps penetrate the skin layers with the aid of absorption enhancers and releases the HA into the deep layers of the skinHA incorporated into the dermis (rapid aesthetic benefit) and induces long term collagen synthesis
12 A Double Blind Vehicle Controlled Trial to Investigate the efficacy and tolerance of Transdermal CL1 (Restylane) versus non-CL1 (Non Crossed Linked HA) in the appearance of photodamaged skin
13 Topical Hyaluronic Acid (HA) Clinical Trial I 100 subjects 2 sites: Women 35 – 65 with moderate to severe photodamage: 40 CL1 (crosslinked HA – Restylane), 40 NCL1 (Non crossed linked HA), 20 Vehicle2 US sitesSubjects and investigators blinded2 week wash out, 12 week trail (evaluations 2,6 and 12 weeks), 4 week post treatment (washout)Apply twice a day clean face.
14 Topical Hyaluronic Acid (HA) Clinical Trial II Visia camera systemObjective evaluationsGoldman-Rao” photographic scale in 5 gradesEvaluation of skin roughness, skin hydration, skin radiance, smoothing effect, overall efficacy and toleranceSubjective Questionnaires :Product QualitiesSubjective improvement.
15 Topical Hyaluronic Acid (HA) Clinical Trial - Washout Evaluation of sustained effect of topical HAPatient discontinued all Topicals at day 90 and were evaluated for sustained effects at day 120Visia photographsClinical evaluations.
49 Assessment of Product Overall Qualities of the Cream
50 Topical Hyaluronic Acid (HA) 90 Day Results Summary I Blinded Investigator evaluations showed highly statistically significant improvement using the topical crosslinked HA (Restylane) over time and vs the non cross linked and vehicle in Skin Roughness, Hydration, Elasticity, Radiance, Smoothing Effect and Overall Efficacy. Most dramatic differences with Smoothing Effect and Overall EfficacyBlinded subjective evaluations showed highly statistically significant improvement using the topical crosslinked HA (Restylane) over time and vs the non cross linked and vehicle in, Hydration, Elasticity and tightness, Texture improvement,, Global Appearance Improvement and Overall Efficacy.
51 Topical Hyaluronic Acid (HA) 90 Day Results Summary II Overall the non crosslinked HA showed better efficiency than the vehicle but was inferior to the crosslinked HAWrinkle evaluation using Goldman-Rao scale was to course a measurement to show statistical differences but clinical photos showed significant improvement using the crosslinked HATolerance: 97 out of 100 patients finished the trial. No dropout because of tolerance issues. No significant complaints of irritation, dryness, itching or redness. No investigator observed untoward effects. Subjects liked the product texture, color, penetration, and ease of application.
52 Topical Hyaluronic Acid (HA) Washout Results Summary Blinded Investigator evaluations showed highly statistically significant continued improvement after 30 day washout using the topical crosslinked HA (Restylane) vs the non cross linked and vehicle which overall lost significant ground on improvementDramatic clinical improvement after washout period in categories of skin roughness, smoothing effect and overall efficiency.
53 Topical Hyaluronic Acid (HA) Discussion Topical crosslinked HA (Restylane) and non crosslinked HA appears penetrate the skin using the unique Ionic Nano Particle Technology (InParT) delivery systemTopical crosslinked HA (Restylane) and to a lesser extent non crosslinked HA appear to have significant aesthetic enhancement effect in this double blind vehicle controlled trial in virtually every category of blinded investigator evaluations and subjective evaluations as well as in clinical photographic assessmentsThe benefits of the topical crosslinked HA (Restylane) continue to improve even when the product is discontinued perhaps indicating a long term benefit to the skin brought forth by collagen remodelingEarly discussion with regulatory attorneys indicates that topical crosslinked HA probably does not need an NDA and can be sold as a cosmecutical.

88 Discussion ITrails compared subjective and blinded investigator assessment pain, as well as preference following Restylane injections in the NLF comparing a novel 4 % lidocaine in nano technology delivery system (NTL4) to commercially available LMX4Results indicate that NTL4 is significantly superior to LMX4 according to blinded subjective bilateral comparisons and blinded investigator observations. Results consistent at one hour and three hours after injection and is related to both half life of lidocaine and decreased initial painNTL4 appears to have significant efficiency with extremely short incubation (15,10 and 5 minutes) after 30 second massage application. Variations in significance of individual onset groups secondary to small n in each group. Differences between initial and early onset study (apparent enhanced effect of NTL4 may be due to 30 vs 20 second application massage)
89 Discussion IIAE’s mild and appear associated with injections except for one subject. Erythema and edema started bilaterally and continued in NTL4 treatment side. Probable cause is lidocaine topical sensitivity.NTL4 show significant promise as a next generation topical anesthetic having significantly enhanced effect and early onset abilityNano technology allows for enhanced rapid penetration of lidocaine through the stratum corneum, epidermis and dermis to the sensory nerves4% lidocaine allows for OTC status: both as a physician used (dispensed) and general consumer useShort incubation times (early onset) will be very attractive to dermatologists and pediatriciansCommercial launch of OTC within months (just need stability testing)
90 Center for Clinical and Cosmetic Research NTL4 (4% Topical Lidocaine Anesthetic Utilizing a Novel Micelle Nano Technology Delivery System): Anesthetic Properties and Lidocaine ToxicityMark S. Nestor, M.D., Ph.D.Glynis R. Ablon, M.D.Center for Clinical and Cosmetic Research
91 Introduction IA recent study showed that NTL4 (Innovatec, Inc), a new topical nanotechnology lidocaine preparation, was significantly more effective than L.M.X.4® (Ferndale laboratories), a commercially available topical lidocaine preparation at decreasing pain upon injection of Restylane in the nasolabial folds.The preparation worked in as little as 5 minutes.Because of the improved capabilities of NTL4 this study will evaluate absorption and potential systemic effects of lidocaine.
92 Introduction IIThe objective of this clinical study is the detection of lidocaine levels in blood after the application of up to 60 grams of NTL4 under occlusion for 60 minutes on the face, abdomen or thighs of ten study participants.Additionally a needle stick test using a subjective VAS pain scale will be used to determine efficacy of the NTL4. Analysis will include comparison of mean VAS scores for the treated and non treated areas.
93 Methods I 10 subjects between 25 and 65 Blood samples (approximately 3-5cc each) were drawn from each participant at baseline (before NTL4 cream is applied*) following central laboratory instructions.NTL4 cream was applied (30 grams) on the whole face of 4 volunteers. Three volunteers had 60 grams of the cream applied on a 600 cm2 area on their abdomen and the remaining three on their thighs under plastic wrap occlusionThe cream was applied on different areas of the body to determine differences in absorption.
94 Methods IINTL4 cream was left on the area for at least 60 minutes. After the 60 minutes, the cream was completely removed using tongue depressors and lint-free wipes as well as alcohol wipes. A second blood sample was taken at this time.Blood samples were taken again at 2, 6 and 24 hours post initial application of the anesthetic creamThe VAS (Visual Analog Pain) scale was used to determine the effectiveness of the topical anestheticThe subject was asked to evaluate the pain experienced at needle stick in the area covered by the topical anesthetic as well as an untreated adjacent area, by responding to a pain intensity scale.
96 Results IPatients’ lab results were negative for any level of lidocaine or lidocaine metabolites.No neurological, cardiovascular, or gastrointestinal indications of lidocaine toxicity were observed.In 100% of the patients raw scores of the VAS showed that patients reported less pain upon needle stick on the treated area when compared to the non-treated area. Table 1 illustrates descriptive data for number of patients, mean scores, and standard deviations for VAS scores on treated and non-treated areas
97 Results II Table 1. VAS Scores N M SD Treated 10 1.1 .95 Non TreatedA one-way analysis of variance was used to test mean differences between the 2 areas. Results indicated that a significant difference exists between the treated and non-treated areas (F [1,18] = 21.0, p<.001).
99 Discussion NTL4 is an extremely effective topical anesthetic Moderate amounts of NTL4 (up to 60 grams under plastic wrap occlusion) showed no blood levels of lidocaine or metabolitesDramatic reduction in VAS pain scale to needle stickNTL4 safe and effective topical anesthetic
101 InParT Drug Delivery System Topical BP: Acne I BP is one of the most effective and enduring acne treatmentsBP dramatically reduces bacteria (p. acnes) without causing bacterial resistance and in fact can reduce bacterial resistance if this has arisen from antibiotic therapy.Reduces the number of yeasts on the skin surface.BP is an oxidizing agent and is keratolytic and comedolytic i.e. it reduces the number of comedonesAnti-inflammatory action
102 InParT Drug Delivery System Topical BP: Acne II Insoluble BP causes skin to stain clothes need better alternativesPrescription strength BP is a Desi Drug. Rapid FDA approval but FDA transitioning to OTC designationOTC BP is a tremendous market opportunityThe active ingredient in Proactiv product is BP: $500,000,000 in annual salesTotal market OTC BP is approximately $2,000,000,000Low dose BP in InParT delivery can be more effective with fewer side effects (irritation and dryness)
103 Topical BP: Acne Clinical Model InParT can theoretically maximize penetration and delivery of BPImproved efficiencyMinimal PB remains on skin surface to lighten skin and stain clothingDelivery system can also work with BP combination compounds
104 Topical BP: Acne Pilot Clinical Study Objective To evaluate the efficacy of the novel INParT topical (BP 3.5%, 1.5% salicylic acid and 3% Hydrogen peroxide) in moderate to severe acne vulgarisDesign open-label treatment phase, randomized, parallel-group maintenance phase in comparison with VC (placebo treatment).
105 Topical BP: Acne Pilot Clinical Study Subjects: 26 patients (male/female 14/12) Duration acne was on average 2-3 yearsTrial Duration: 8 week Twice a dayMain Outcome Measures Overall disease severity, global improvement, and lesion counts. Patients were seen at baseline, defined as the visit when treatment was initiated, and again at 2, 4, 8 weeks of treatment. Lesion count, global response and photographsThe global response to treatment scores were assessed by comparing the patient's condition with baseline photographs and then were graded from 0 to 6 as follows:0, completely cleared;1, approximately 90% improved;2, approximately 75% improved;3, approximately 50% improved;4, approximately 25% improved;5, no change; and6, exacerbation.
106 Topical BP: Acne Pilot Clinical Study Results:After 8 weeks or less treatment the mean reductions from baseline in non inflammatory and inflammatory lesion count, were 66% and 69% with this novel formulation in comparison with placebo where improvement was 3.7% and 5.2%At week 4, more than 80% of patients had maintained a 50% or greater global improvement from baseline, and more than 40% had maintained a 75% or greater global improvement.
