Theravance Biopharma, Inc. (NASDAQ: TBPH) (“Theravance Biopharma”) and Trek Therapeutics (“TREKtx”) today announced that TREKtx has initiated a Phase 2a clinical trial of TD-6450, a next-generation investigational NS5A inhibitor in development to treat patients with hepatitis C virus (HCV). Theravance Biopharma recently granted TREKtx an exclusive worldwide license for the development, manufacturing, use, marketing and sale of TD-6450 as a component in combination HCV products. Other terms of the transaction have not been disclosed.
The Phase 2a clinical trial will evaluate faldaprevir (FDV), an HCV protease inhibitor, combined with TD-6450 and ribavirin (RBV) in patients infected with HCV genotype 4. The trial is being conducted in the United States.
Mathai Mammen, M.D., Ph.D., Senior Vice President of Research and Development at Theravance Biopharma commented, “We are pleased to see the initiation of this Phase 2a clinical trial with TD-6450. This NS5A inhibitor has shown robust antiviral activity in a Phase 1 trial in patients with HCV genotype 1, as well as preclinical potency against both wild type HCV and resistance-associated variants. We believe that its antiviral activity, in combination with other antivirals, may help improve cure rates and/or reduce treatment times for appropriate patients. We are especially pleased to collaborate with TREKtx and support their commitment to delivering novel and accessible combination HCV treatments to patients worldwide.”
“We are very excited about dosing our first genotype 4 patients in this combination study. If safety and efficacy are demonstrated, the goal is to initiate clinical trials in Egypt next year, where the need is enormous,” said Dr. Robert Hindes, Chief Medical Officer of Trek Therapeutics.
About TD-6450
Theravance Biopharma discovered TD-6450, a multivalent NS5A inhibitor designed to have improved antiviral activity against genotype 1 resistance-associated variants (RAV) resistant to first generation NS5A inhibitors. TD-6450 has successfully completed Phase 1 studies in both healthy volunteers and HCV patients.
About Faldaprevir
Faldaprevir is a protease inhibitor that TREKtx acquired from Boehringer Ingelheim. FDV has completed Phase 3 studies in combination with pegylated interferon and RBV.
About HCV
Hepatitis C is an infectious disease of the liver. Of people infected, 55 to 85 percent will develop chronic infection, and 75 percent of those with chronic infection will develop chronic liver disease.
The U.S. Centers for Disease Control and Prevention estimates 2.7 million individuals in the United States have active hepatitis C virus (HCV) infection, most of whom are “baby boomers.” In the United States, chronic HCV infection is the leading cause of cirrhosis and liver cancer and the most common reason for liver transplantation. Worldwide, more than 135 million people have chronic HCV infection and most are undiagnosed.

TREKtx is a private, clinical stage public benefit corporation developing treatments for serious infections. Its mission is to profitably develop affordable and accessible medicines to treat infectious diseases and to commercialize them for global populations.

The mission of Theravance Biopharma (NASDAQ: TBPH) is to create value from a unique and diverse set of assets: an approved product; a development pipeline of late-stage assets; and a productive research platform designed for long-term growth.
Our pipeline of internally discovered product candidates includes potential best-in-class opportunities in underserved markets in the acute care setting, representing multiple opportunities for value creation. VIBATIV® (telavancin), our first commercial product, is a once-daily dual-mechanism antibiotic approved in the U.S., Europe and certain other countries for certain difficult-to-treat infections. Revefenacin (TD-4208) is an investigational long-acting muscarinic antagonist (LAMA) being developed as a potential once-daily, nebulized treatment for COPD. Axelopran (TD-1211) is an investigational potential once-daily, oral treatment for opioid-induced constipation (OIC). Our earlier-stage clinical assets represent novel approaches for potentially treating diseases of the lung and gastrointestinal tract and infectious disease. In addition, we have an economic interest in future payments that may be made by GlaxoSmithKline plc pursuant to its agreements with Theravance, Inc. relating to certain drug development programs, including the combination of fluticasone furoate, umeclidinium and vilanterol (the “Closed Triple”).
