New Leaf Venture Partners Announces $12 Million Financing in Tioga Pharmaceuticals

NEW YORK & MENLO PARK, Calif.--(BUSINESS WIRE)--Jan. 9, 2006--New Leaf Venture Partners (NLV Partners) announced today that it has invested in a $24 million Series A private equity financing in Tioga Pharmaceuticals Incorporated. Tioga Pharmaceuticals is engaged in the development of novel therapies for the treatment of gastrointestinal diseases. Tioga is developing asimadoline, a proprietary small molecule, for treating irritable bowel syndrome (IBS) and post operative ileus.

NLV invested $12 million in the Series A financing, which was led by Forward Ventures. BB Biotech Ventures II also participated in the financing. The capital will be used to fund a 600 patient phase IIb clinical trial for irritable bowel syndrome and a 130 patient phase IIa trial for post operative ileus.

Dr. Allen Mangel, Tioga's Chief Medical Officer and the former worldwide head of gastrointestinal clinical development at GlaxoSmithKline, stated: "I am excited to be leading the clinical development of asimadoline. I believe this is the most promising medicine in development today for the treatment of IBS."

Asimadoline is a proprietary small molecule therapeutic discovered and developed by Merck KGaA of Darmstadt, Germany. Tioga has acquired all rights to asimadoline from Merck. The compound has been tested in nearly 800 subjects and demonstrated a promising safety profile. It has shown encouraging clinical efficacy for the treatment of irritable bowel syndrome and has the potential for treating other gastrointestinal diseases.

In connection with the financing, James Niedel, M.D., Ph.D., a managing director at NLV Partners, has joined Tioga's board of directors. Dr. Niedel commented, "Tioga was formed to address diseases with broad markets and clear, unmet medical needs, such as Irritable Bowel Syndrome (IBS), which affects 70 million people in the United States and Europe. Early clinical data suggest that asimadoline is safe, with enormous potential to improve the lives of patients with this disease. We at New Leaf look forward to working with Dr. Allen Mangel, Tioga's Chief Medical Officer and one of the world's leading experts in IBS, to complete its clinical development."
