WATERTOWN, Mass.--(BUSINESS WIRE)--

Enanta Pharmaceuticals, Inc., (ENTA) a research and development-focused biotechnology company dedicated to creating small molecule drugs in the infectious disease field, today announced that additional data from AbbVie’s M13-393 study, referred to as PEARL-I, will be presented in an oral presentation at 5:15 p.m. ET today at The Liver Meeting, the 64th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in Washington, D.C.

In PEARL-I, SVR12 rates of 95% (40/42) in hepatitis C (HCV) GT-1b treatment-naïve patients and 90% (36/40) among prior null responders will be presented in this intent-to-treat analysis. Two patients in the treatment-naive arm did not achieve SVR12 due to loss to follow up. In the null responder arm, one patient experienced breakthrough and three patients relapsed.

PEARL-I is a phase-2b, interferon-free, 320 patient study being conducted by AbbVie to evaluate the once-daily, two-DAA regimen consisting of ABT-450/r (protease inhibitor plus ritonavir) + ABT-267 (AbbVie’s NS5A inhibitor) in HCV treatment-naïve patients and treatment-experience patients. GT-1b treatment arms are ribavirin-free and also include cirrhotic patients while GT-4 arms explore treatment with and without ribavirin.

“We are very encouraged by the strong SVR12 rates from this simplified 2-DAA, once-daily regimen that includes our lead HCV protease inhibitor, ABT-450,” commented Jay R. Luly, Ph.D., President and Chief Executive Officer. “We look forward to data from Phase 3 studies of three-DAA regimens containing ABT-450 being reported in the coming months.”

Protease Inhibitor Collaboration with AbbVie (formerly the research-based pharmaceutical business of Abbott Laboratories)

In December 2006, Enanta and Abbott announced a worldwide agreement to collaborate on the discovery, development and commercialization of HCV NS3 and NS3/4A protease inhibitors and HCV protease inhibitor-containing drug combinations. ABT-450 is a protease inhibitor identified as a lead compound through the collaboration. Under the agreement, AbbVie is responsible for all development and commercialization activities for ABT-450. Enanta received $57 million in connection with signing the collaboration agreement, has received $55 million in subsequent clinical milestone payments, and is eligible to receive an additional $195 million in payments for regulatory milestones, as well as double-digit royalties worldwide on any revenue allocable to the collaboration’s protease inhibitors. Also, for any additional collaborative HCV protease inhibitor product candidate developed under the agreement, Enanta holds an option to modify the U.S. portion of it rights to receive milestone payments and worldwide royalties. With this option, Enanta can fund 40 percent of U.S. development costs and U.S. commercialization efforts (sales and promotion costs) for the additional protease inhibitor in exchange for 40 percent of any U.S. profits ultimately achieved after regulatory approval instead of receiving payments for U.S. commercial regulatory approval milestones and royalties on U.S. sales of that protease inhibitor.

About Enanta

Enanta Pharmaceuticals is a research and development-focused biotechnology company that uses its robust chemistry-driven approach and drug discovery capabilities to create small molecule drugs in the infectious disease field. Enanta is discovering and developing novel inhibitors designed for use against the hepatitis C virus (HCV). These inhibitors include members of the direct acting antiviral (DAA) inhibitor classes – protease (partnered with AbbVie), NS5A (partnered with Novartis) and nucleotide polymerase – as well as a host-targeted antiviral (HTA) inhibitor class targeted against cyclophilin. Additionally, Enanta has created a new class of antibiotics, called Bicyclolides, for the treatment of multi-drug resistant bacteria, with a focus on developing an intravenous and oral treatment for hospital and community MRSA (methicillin-resistant Staphylococcus aureus) infections.

The full detailed presentation of ABBV/ENTA’s six phase-3 HCV trials for the initial NDA (the first six trials listed in #msg-93647264) is planned for EASL in Apr 2014, according to ABBV’s CS webcast today. Top-line data from these trials will be released as the data become available, starting with SAPHIRE-1 and SAPHIRE-2 before 2013 year-end.

ABBV/ENTA’s Global Phase-3 HCV Program

[Updated for release of top-line data from SAPHIRE-1.]


ABBV/ENTA have 9 global phase-3 trials testing an all-oral
regimen in HCV genotype-1a/1b : 6 trials that comprise the initial
NDA/MAA submissions in 2Q14, and 3 trials for subsequent use.
Full details of the 6 trials comprising the initial NDA/MAA will
be presented at the EASL conference in Apr 2014.

All 9 of these global phase-3 trials include the 3-DAA combination
of the protease inhibitor, ABT-450/r (licensed by ABBV from ENTA);
the NS5A inhibitor, ABT-267 (from ABBV’s pipeline); and the non-
nucleoside polymerase inhibitor, ABT-333 (from ABBV’s pipeline).
Some of these trials also include ribavirin in one or both trial arms.

(ABBV/ENTA are testing the 2-DAA regimen of ABT-450/r + ABT-267
in a phase-3 trial for genotype-1b patients in Japan [#msg-91870291]
and in various phase-2 trials globally.)
