Presidio Pharmaceuticals to Collaborate with Boehringer Ingelheim

Presidio Pharmaceuticals, Inc. announced today a non-exclusive collaboration with Boehringer Ingelheim for a Phase IIa clinical trial of an interferon-free, all-oral, direct-acting antiviral (DAA) combination treatment for patients with chronic hepatitis C virus (HCV) infection. The collaborative trial will evaluate Presidio’s pan-genotypic HCV NS5A inhibitor (PPI-668) in combination with Boehringer Ingelheim’s HCV protease inhibitor faldaprevir (BI201335) and its non-nucleoside HCV polymerase inhibitor (BI207127), with or without ribavirin.

Both companies have agreed to initiate the Phase II, 12-week treatment study in the second quarter of 2013. The trial will measure on-treatment antiviral responses and sustained virologic response rates (SVR) to the triple DAA combination regimen, with or without ribavirin. Presidio Pharmaceuticals will have primary operational responsibility for the trial, in close collaboration with Boehringer Ingelheim.

“With the potent, complementary antiviral activities of PPI-668, faldaprevir, and BI207127, the present study focuses on patients with HCV genotype-1a infection, which has been harder to treat than HCV genotype-1b in many studies. The study will assess the potential of this three-drug oral regimen to achieve high rates of sustained viral clearance in hepatitis C patients, with good tolerance,” said Dr. Nathaniel Brown, Presidio’s Chief Medical Officer.

Sustained virologic response results at 4- and 12-weeks post-treatment are expected to be available in the fourth quarter of 2013. Both companies continue to retain all rights to their respective compounds during this collaboration.
