Gerbsman Partners (www.gerbsmanpartners.com) has been retained by Tarsa Therapeutics, Inc. (www.tarsatherapeutics.com) to solicit interest for the acquisition of all, or substantially all, the assets of Tarsa Inc.  (pls see attached Tarsa sales letter.pdf for additional detail information)

Tarsa Therapeutics, founded in 2009, is a privately held NDA-ready company focused on advancing its lead product, TBRIA to approval and commercialization.  TBRIA is a proprietary oral formulation containing recombinant salmon calcitonin (rsCT) for the treatment of postmenopausal osteoporosis.

Tarsa was funded ($78.4mm) by a syndicate of  four life sciences venture capital funds including: MVM Life Science Partners, Quaker Partners,  Novo A/S and Foresite Capital, in conjunction with Unigene Laboratories (now Enteris Biopharma), a leader in the design, delivery, manufacture and development of peptide-based therapeutics.  Tarsa Therapeutics is headquartered in Philadelphia, PA.

Tarsa has exclusive license rights from Enteris Biopharma to 12 issued US Patents covering Active Pharmaceutical Ingredient (API) manufacturing and oral peptide delivery technology supporting TBRIA.  Tarsa also has exclusive license to Global patents covering the same technologies. A patent application for a room temperature stable formulation of TBRIA if granted could extend the IP runway to August, 2037. The oral formulation patents qualify for Orange book listing preventing introduction of generic versions of TBRIA.  Tarsa also has an issued patent for a combination product consisting of oral calcitonin plus small molecules for the treatment of osteoarthritis.

Impact of Tarsa Therapeutics Products and Why Tarsa Therapeutics Assets are Attractive:TBRIA™ Tarsa’s Phase III Asset -Unique and Differentiated Therapy for Osteoporosis

 1.  TBRIA product profile highlights:

a.  Positive Phase III results demonstrated superiority to existing nasal calcitonin

b.  Product profile addresses significant unmet medical need in the market place

c. Year 5 peak US sales exceeding $550mm

2.  TBRIA will provide an antiresorptive product with a previously approved molecule and a distinct mechanism of action to address the unmet medical need arising from increasing safety issues with bisphosphonates (BPs) including:  atypical subtrochanteric fractures, risk of osteonecrosis of the jaw, & atrial fibrillation and for patients unable to tolerate BPs or SERMS

3. TBRIA™ will be the only new antiresorptive therapy on the market with no new antiresorptive therapies in development on the horizon, lack of competition lends to 50% of the OP market Rxs can be reached with only 150 reps

Significant Commercial Opportunity

Emergent AEs associated with the standard of care BPs has led > 5 million women to discontinue therapy for Osteoporosis (OP),  while initiation of therapy for newly diagnosed women has also dropped drastically

a. TBRIA has the potential to be a significant commercial product with peak US sales potential  in excess of  USD $550 million with a sales force of only 150 representatives

Majority of TBRIA sales will come from significant penetration of the “lapsed” patient population (5 million patients) that have discontinued bisphosphonate treatment

An immediate sales opportunity at market entry  in the US of ~ $100 mm exists for TBRIA to rapidly cannibalize nasal calcitonin prescriptions given TBRIA’s superior ease of administratio

b. Extensive market research (> 1200 high prescribing physicians) indicates that prescribers view TBRIA as a differentiated alternative with anticipated use in ~ 20% of new and existing treated osteoporotic patients and > 30% within the  discontinued patients population

3.  Tarsa Therapeutics Assets Intellectual Property (“IP) and Market Protectio

a.  Currently two distinct patent estates covering 12 US patents provide IP protection until 12/2029 for TBRI

b. These include global patent coverage for API manufacturing until June 2026 and  December, 2029 for the oral peptide formulation technology

c.  Patent pending for room temperature stable formulation of TBRIA may extend IP to August 2037

d.  Up to 4 formulation patents are Orange Book eligible to prevent generic entries to TBRIA

e.  The ANDA path is not viable option per FDA peptide/protein based therapeutic policy

4.  Regulatory Path Forward

a.  The TBRIA 505(b)(2) NDA received a CRL relating principally to the reference listed drug, Miacalcin Nasal Spray, demonstrating efficacy but failing to separate from placebo

b.  Tarsa has agreed with FDA that a single confirmatory de-risked, 2-arm, 48 week study comparing TBRIA with nasal spray calcitonin alone will satisfy the 505(b)(2) requirements. Initiation of the clinical study in late 2018 with positive results will result in an approved product in first half 2021.  Given the TBRIA versus Miacalcin nasal spray results from the completed Phase III ORACAL study there is a high likelihood of success.

5.  Chemistry, Manufacturing & Controls (“CMC”)

a.  API inventory valued at ~ $20 mm ($8 mm in house, $12 mm paid secured rights), sufficient to support  >$500mm in sales

b.  Larger commercial API requirements for follow on indications are addressed by rDNA process that affords greater scale and lower costs than traditional peptide chemical synthesis

c.  Tablet manufacture scaled to commercial size batch of 500,000 completed


A higher strength version of TBRIA can provide significant upside revenue potential through expansion into other indications such as: Treatment of symptomatic osteoarthritis (>$1 billion) and pain associated with recent vertebral fracture (~$200 mm).
