Webcast and Conference Call today at 4:30 p.m. ET

• Royalty revenue was $9.0 million
• R&D expense increased to $13.0 million in support of pipeline development
• Cash and marketable securities totaled $240.9 million at March 31, 2017

Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a research and development-focused biotechnology company dedicated to creating small molecule drugs for viral infections and liver diseases, today reported financial results for its fiscal second quarter ended March 31, 2017.

Enanta's cash, cash equivalents and short-term and long-term marketable securities totaled $240.9 million at March 31, 2017. This compares to a total of $242.2 million in such accounts at September 30, 2016. Enanta expects that its current cash, cash equivalents and marketable securities will be sufficient to meet the anticipated cash requirements of its existing business and development programs for the foreseeable future.

Fiscal Second Quarter Ended March 31, 2017 Financial Results

Total revenue for the three months ended March 31, 2017 was $9.0 million, compared to $13.0 million for the three months ended March 31, 2016. For the six months ended March 31, 2017, total revenue was $19.4 million, compared to $61.4 million for the same period in 2016. For the three and six month periods ended March 31 2017, revenue consisted exclusively of royalties earned on AbbVie's worldwide net sales of HCV regimens containing paritaprevir. For the 2016 six month period, revenue consisted primarily of royalty revenues as well as a $30.0 million milestone payment for the reimbursement approval of VIEKIRAX® in Japan. Milestone payments and royalties have varied significantly from period to period, and we expect that variability to continue in the future.

Research and development expenses totaled $13.0 million for the three months ended March 31, 2017, compared to $9.1 million for the three months ended March 31, 2016. For the six months ended March 31, 2017, research and development expenses totaled $25.5 million compared to $18.2 million for the same period in 2016. The increase in research and development expenses was primarily due to increased preclinical and clinical costs associated with the progression of Enanta's wholly-owned R&D programs in non-alcoholic steatohepatitis (NASH)/primary biliary cholangitis (PBC), respiratory syncytial virus (RSV) and hepatitis B virus (HBV).

General and administrative expenses totaled $5.5 million for the three months ended March 31, 2017, compared to $4.4 million for the three months ended March 31, 2016. For the six months ended March 31, 2017, general and administrative expenses was $10.4 million, compared to $8.2 million for the same period in 2016. For the three month period, the increase in general and administrative expenses was primarily due to increases in stock-based compensation expense driven by increased headcount. For the six month period, the increase was due to increased headcount as well as achievement of milestones under existing performance-based stock awards.

Enanta recorded an income tax benefit for the three months ended March 31, 2017 of $3.6 million compared to an income tax expense of $1.6 million for the same period in 2016. The Company's estimated annual effective tax rate for fiscal 2017 of 33.0 percent was slightly below the statutory rate of 35.0 percent due to the availability of federal research and development tax credits.

Net loss for the three months ended March 31, 2017 was $5.4 million, or $(0.28) per diluted common share, compared to net loss of $1.6 million, or ($0.09) per diluted common share, for the corresponding period in 2016. For the six months ended March 31, 2017, net loss was $10.4 million, or ($0.54) per diluted common share, compared to net income of $24.5 million, or $1.28 per diluted common share, for the corresponding period in 2016.

'With our second partnered protease inhibitor product, glecaprevir, expected to launch starting in August as part of AbbVie's new, investigational G/P treatment for HCV, the prospects for additional milestone and royalty payments to us for G/P are significant,' stated Jay R. Luly, Ph.D., President and Chief Executive Officer, Enanta. 'Any such payments, coupled with our existing financial resources, will allow us to advance our clinical program in NASH/PBC and also fund our additional R&D programs, including our lead compound EDP-938 for RSV, scheduled to begin clinical development later this year.'

Development Program and Business Review

• Enanta presented new preclinical data on EDP-305, its wholly-owned FXR agonist for non-alcoholic steatohepatitis, at the International Liver Congress™ (ILC) 2017 in Amsterdam. Data from three poster presentations presented at the Congress demonstrated that EDP-305 is a potent Farnesoid X receptor (FXR) agonist that has been shown to reduce expression of fibrogenic genes, reduce fibrosis progression and improve non-alcoholic fatty liver disease (NAFLD) activity scores (NAS) in a variety of preclinical models.
• Enanta expects to present clinical data from our ongoing Phase 1 clinical study of EDP-305 in healthy volunteers and presumed NAFLD subjects and to initiate NASH-enabling studies in the second half of this year. A Phase 2 study in PBC is expected to begin in the fourth quarter of calendar 2017 and Phase 2 studies in NASH are expected to begin in early 2018.
• Also at the ILC, AbbVie presented new data from its investigational, pan-genotypic, ribavirin-free regimen for hepatitis C virus (HCV) consisting of a combination of glecaprevir/pibrentasvir (G/P). Data from the EXPEDITION-1 study demonstrated that 99 percent (n=145/146) of chronic HCV infected patients with genotype 1, 2, 4, 5 or 6 and compensated cirrhosis (Child-Pugh A) achieved sustained virologic response at 12 weeks post-treatment (SVR) with G/P. This high SVR rate was seen following 12 weeks of G/P treatment without ribavirin. Data were also presented at the ILC from the ENDURANCE-3 study. In this study, 95 percent (n=149/157) of genotype 3 (GT3) chronic HCV-infected patients without cirrhosis and who were new to treatment, achieved sustained virologic response at 12 weeks post-treatment (SVR) following 8 weeks of treatment with G/P.
• In March, Enanta announced the Japanese Ministry of Health, Labour and Welfare (MHLW) granted priority review designation to AbbVie's G/P combination for the treatment of all major genotypes (GT1-6) of chronic hepatitis C virus (HCV) infection. AbbVie had submitted the NDA for the G/P regimen in Japan in February 2017. The NDAs for G/P in the U.S and Japan have been granted priority review designation, and the MAA for G/P has been granted accelerated assessment in the E.U.

Upcoming Events and Presentations

On June 25 at the XIX International Symposium on Respiratory Viral Infections in Berlin, Germany, Enanta will present data on EDP-938, its respiratory syncytial virus inhibitor candidate in an oral presentation titled: 'EDP-938, a Novel Non-Fusion Replication Inhibitor of Respiratory Syncytial Virus, Demonstrates Potent Antiviral Activities both In Vitro and In Vivo'.

• Enanta plans to issue its fiscal third quarter financial results press release, and hold a conference call regarding those results, on August 7, 2017.

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 for viral infections and liver diseases. Enanta's research and development efforts are currently focused on the following disease targets: non-alcoholic steatohepatitis (NASH)/ primary biliary cholangitis (PBC), respiratory syncytial virus (RSV) and hepatitis B virus (HBV).

Enanta has discovered novel protease inhibitors for use against the hepatitis C virus (HCV). These protease inhibitors, developed through Enanta's collaboration with AbbVie, include paritaprevir, currently marketed in AbbVie's HCV regimens, and glecaprevir (ABT-493), Enanta's second protease inhibitor product, which AbbVie is developing as part of its investigational, pan-genotypic HCV regimen of glecaprevir/pibrentasvir (G/P) now in registration in the U.S., the E.U. and Japan and other jurisdictions. Royalties and any further milestone payments from this collaboration will provide additional funding for Enanta's earlier development programs, including its Phase 1 FXR agonist program for NASH/PBC, and its preclinical programs for HBV and RSV.
