Tamarkin Pharmaceutical Innovation Ltd.



OVERVIEW

Tamarkin Pharmaceutical Innovation Ltd. is a biopharmaceutical company engaged in the discovery and development of drugs, including topical treatments for skin disorders as well as systemic diseases, including life threatening ones. Our novel synthetic "Dual Action Pro-drugs" (DAPDRUGs), are programmed to penetrate the target organ and simultaneously exert a plurality of therapeutic effects.

Our most advanced product, TU-2100, is an innovative topical medication, based on the DAPDRUG concept. It was discovered by our founder and CEO, Dr. Dov Tamarkin. TU-2100 was designed to treat acne, psoriasis, seborrhea and hair growth disorders, which afflict many millions of people worldwide, for which there are currently no satisfactory treatments. TU-2100 has been tested in a Phase II clinical trial and found effective in alleviating the symptoms of acne without causing skin irritation. We are currently in the process of evaluating TU-2100's effects in psoriasis and seborrhea.

In line with our pipeline expansion strategy, we have recently initiated a joint project with a Weizmann Institute - based company, BALM Ltd., whereby our DAPDRUG concept is utilized in the creation of new peptide drugs, aimed to treat bacterial and fungal infections, as well as cancer. Initial results indicated that these new molecules possess very potent antibacterial activity, with no anticipated side effects.

OUR SOLUTION

DAPDRUGs
Dual Action Pro-Drugs (DAPDRUGs) are TPI's innovative therapeutic molecules. The DAPDRUG family has unique and most desirable medical qualities. They can be used effectively to treat dermatological, inflammatory and infectious disorders. DAPDRUGs penetrate the skin effectively, liberate active moieties inside the skin and treat the disorders in multiple ways. DAPDRUGs can be marketed on several categories, such as: prescription medications, OTC (over the counter) products and cosmetics. Our first DAPDRUG, TU-2100 is in an advanced stage of development, as detailed below. Further DAPDRUGS have been synthesized in our laboratory and our biological studies revealed that three of them inhibit keratinocyte proliferation at micro-Molar concentrations, suggesting their potential use in psoriasis and other hyperproliferation disorders. The synthesis and evaluation of additional compounds is underway.

The Lead Product - TU-2100
TPI's lead product, TU-2100, is a DAPDRUG, aimed to treat acne, psoriasis, seborrhea and hair growth disorders. Due to its unique molecular structure, it seeps deep into the skin and simultaneously exerts anti-proliferative, antibacterial, anti-inflammatory and sebostatic effects. Particularly, TU-2100 can penetrate the sebaceous gland, acne's origin and affects the overproduction of oil, while also treating the bacteria and the inflammation. TU-2100 was tested in clinically, and found effective in alleviating the symptoms of acne, psoriasis and seborrhea, without causing skin irritation.

TU-2100 is Safe and Effective in the Treatment of Oily Skin
A "cosmetic" clinical study was undertaken to assess the safety of TU-2100 lotion and to determine its effect on sebum excretion rate (SER). The study, which was performed by Dr. A. Kligman, a leading dermatologist from the University of Pennsylvania. Sebum excretion rates declined by 30-44%, reaching normal levels within 4 weeks of treatment in all study volunteers. This observation is particularly important, in light of the current belief that "No topical therapies influence the production of sebum" (Leyden J, New England Journal of Medicine, 1997). Thus, TU-2100 possesses a unique mode of action. It does not appear to act like any of the existing topical agents in the alleviation of excessive sebum excretion.

TU-2100 is Safe and Effective in Acne Therapy
A double blind, placebo controlled Phase II study in acne patients revealed that TU-2100 10% is safe and effective. The study, which was randomized, double blind and placebo controlled, was conducted in three European university hospitals, in full compliance with the international regulations of clinical studies.

TU-2100's effect was noted soon after commencement of treatment, reaching statistically significant reduction in lesion count after three weeks. Fifty-nine percent (59%) reduction in lesion count was recorded after 12 weeks of treatment. The Placebo reduced lesion number by 23%, with no statistical significance comparing to baseline. TU-2100 was found to be non-irritant. No occurrence of skin irritation was noted in the TU-2100 10% group.

As presented below, the response to TU-2100 treatment was very high - all patients experienced 25% improvement and 10 out of 12 had more than 50% decrease of total lesion count.

Vehicle TU-2100 10% p-Value
Responders Non Responders Responders Non Responders
>25% Decrease of Total Lesion Count 7 6 12 0 <0.001
>50% Decrease of Total Lesion Count 6 7 10 2 0.097

Comparison with Current Topical Acne Therapy
In an effort to assess the clinical significance of TU-2100's effects, we compared our Phase II results with published data on the effect of Avita Gel 0.025% and Retin A, which is considered the "gold standard" in acne. As illustrated, Retin A therapy exerted 37% reduction of lesions after 6 weeks of treatment and 45% improvement after 12 weeks. From our Phase II study results, TU-2100 seems to be superior to Retin A in several ways:



  • All TU-2100-treated patient respond to treatment

  • TU-2100 acts faster than the current medications.
  • TU-2100's magnitude of effect seems to be higher than other topical medications.
  • TU-2100 inhibits sebum production (and consequently, skin oiliness), unlike other topical medications.
  • TU-2100 is non-irritant.

    TU-2100 is Potentially Effective in Seborrheic Dermatitis
    Based on the results of the described above "cosmetic" study, we initiated a Phase II study in seborrheic dermatitis patients. The results of this study may expand the applicability of TU-2100 and further increase the value of this project in terms of licensing arrangements.

    TU-2100 is Potentially Effective in Psoriasis (initial results)
    In an exploratory experiment, five patients with psoriasis were treated with TU-2100 Gel. The interim results look very promising. 3 of the five patients had marked clearance of the psoriatic plaques and skin thickness was markedly reduced after 7-10 days of treatment.

    Additional Active Dermatological Agents
    Following the success of our lead product, new dual action pro-drugs have recently been synthesized and tested for their effects on keratinocyte cell cultures. Our initial studies have revealed that three such compounds inhibit keratinocyte proliferation at micro-Molar concentrations, suggesting their potential use in psoriasis and other diseases of cell proliferation. The synthesis of additional compounds is underway in our laboratories.

    Modified Antimicrobial and anti-cancer Peptides
    Recently, we have initiated a 50:50 joint project with a Weizmann Institute - based company, BALM Pharmaceutical Ltd., whereby our DAPDRUG technology principles are utilized in the creation of new peptide drugs, aimed to treat bacterial and fungal infections, as well as cancer. Initial results indicated that these new molecules act against gram-negative bacteria, e.g., Pseudomonas aeroginosa and other pathogens, which are involved in several systemic infectious diseases, including life threatening ones.

    OUR STRATEGY

    We have made a strategic decision to be a leading drug development company, utilizing our proprietary DAPDRUG platform. While our original focus was solely in dermatology, we gradually recognized that the DAPDRUG concept is effective in systemic therapy. With this idea in mind, we initiated our collaboration with BALM Pharmaceuticals. We are currently evaluating other joint ventures in the same fashion.

    In order to expedite our potential opportunities we undertake the following actions:
  • Accelerate global adoption of our solution by continuing to form and develop strategic alliances and corporate partnerships with leading pharmaceutical companies.

  • Enhance our R&D capabilities and expand our project line.
  • Continue to develop additional molecules from the DAPDRUG platform.
  • In-license new projects.

    BUSINESS DEVELOPMENT - TOWARDS STRATEGIC PARTNERSHIPS
    Our intensive efforts in business development are on-going.
    In July 2001, we signed an MOU with the Italian company Istituto Biochimico Italiano Giovanni Lorenzini S.p.A. (IBI). IBI will conduct and fund Phase IIb and subsequently, Phase III studies with our lead molecule TU-2100. The drug will then be registered in Europe and IBI will have exclusive right to sell TU-2100-based products in Italy. IBI has paid us an initial upfront payment and will pay further sums according to milestones, as well as royalties on sales upon commercialization. In November 2002, TPI signed an additional license agreement with Giangzhoe Consun Pharmaceutical Corp, a Chinese company, granting Consun marketing rights for TU-2100 based cosmetics in China, Hong Kong and Taiwan. Further negotiations with companies around the globe are underway.

    Side by side with the primary track of TU-2100, new molecules from the DAPDRUG technology platform have been synthesized and tested successfully in laboratory experiments.

    PROPRIETARY RIGHTS
    Patents, to protect the use TU-2100 and related dual action pro-drugs and their uses in skin disorders have been prepared and submitted worldwide. In January 2001, our first patent, covering a broad range of therapeutic molecules and a wide domain of applications patent issued in the USA (6,180,669), Australia and Singapore. We expect further approvals in the very near future.
