• Royalty revenue from paritaprevir-containing regimens was $13.0 million
• Cash and marketable securities totaled $245.6 million at March 31, 2016

WATERTOWN, Mass.--(BUSINESS WIRE)--May 9, 2016-- 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, 2016.

Enanta’s cash, cash equivalents and short-term and long-term marketable securities totaled $245.6 million at March 31, 2016. This compares to a total of $209.4 million in such accounts at September 30, 2015. Enanta expects that its current cash, cash equivalents and marketable securities will be sufficient to meet the anticipated cash requirements of its existing business for the foreseeable future.

Fiscal Second Quarter Ended March 31, 2016 Financial Results

Revenue for the three months ended March 31, 2016 was $13.0 million, compared to $57.4 million for the three months ended March 31, 2015. For the six months ended March 31, 2016, revenue was $61.4 million compared to revenue of $134.9 million for the same period in 2015. The decrease in revenue in the 2016 periods was due primarily to the fact that revenue in the comparable periods in 2015 included the $50.0 million milestone payment earned in January 2015 for the European commercialization regulatory approval of VIEKIRAX™, and the six-month period in 2015 also included the $75.0 million milestone earned in December 2014 for the approval of VIEKIRA PAK® in the United States. The revenue decrease for the six month period due to the decrease in milestone payments was partially offset by higher royalties earned during the first half of fiscal 2016 from contractually specified portions of AbbVie’s worldwide net sales of HCV regimens containing paritaprevir. Enanta began earning royalties from AbbVie upon its HCV product launch in Enanta’s first fiscal quarter of 2015. Enanta’s milestone payments, royalties and other payments received from collaborations have varied significantly from period to period, and are expected to continue to do so.

Research and development expenses totaled $9.1 million for the three months ended March 31, 2016, compared to $5.4 million for the three months ended March 31, 2015. For the six months ended March 31, 2016, research and development expenses were $18.2 million, compared to $9.9 million for the same period in 2015. The increase in the three and six month periods was primarily due to increased pre-clinical and clinical costs associated with Enanta’s wholly-owned R&D programs in NASH, RSV, HBV and HCV cyclophilin.

General and administrative expenses totaled $4.4 million for the three months ended March 31, 2016, compared to $3.4 million for the three months ended March 31, 2015. For the six months ended March 31, 2016, general and administrative expenses were $8.2 million compared to $6.2 million for the same period in 2015. The increase in the three and six month periods primarily reflects increases in stock-based compensation expense driven by increased headcount and additional equity grants.

Income tax expense for the three months ended March 31, 2016 was $1.6 million compared to $20.0 million for the corresponding period in 2015. During the three months ended March 31, 2016, Enanta increased its estimate of its annual effective tax rate for fiscal 2016, which resulted in an income tax provision despite a pre-tax loss for the quarter. Income tax expense for the six months ended March 31, 2016 was $11.3 million compared to $48.5 million for the corresponding period in 2015, representing annual effective tax rates of 31.5% and 40.7%, respectively, for those periods. For the six months ended March 31, 2016, Enanta’s effective tax rate was lower than that in the comparable period of 2015 primarily due to lower state income taxes and higher federal research and development tax credits, which are factored into the annual effective tax rate.

Net loss for the three months ended March 31, 2016 was $1.6 million, or ($0.09) per diluted common share, compared to net income of $28.8 million or $1.49 per diluted common share, for the corresponding period in 2015. Net income for the six months ended March 31, 2016 was $24.5 million, or $1.28 per diluted common share, compared to net income of $70.8 million or $3.67 per diluted common share, for the corresponding period in 2015.

“Enanta remains in a strong financial position and continues to receive royalties from paritaprevir-containing regimens marketed globally,” commented Jay R. Luly, Ph.D., President and Chief Executive Officer. “These ongoing royalties and our strong cash balance will continue to support our wholly-owned programs, including our cyclophilin candidate, EDP-494, currently in phase 1 development, and our NASH candidate, EDP-305, which is expected to begin phase 1 clinical development in the second half of calendar 2016.”

Development Program and Business Review

• In April, new data on Enanta’s second protease inhibitor, ABT-493, co-formulated in combination with AbbVie’s NS5A inhibitor ABT-530, was presented at The Liver Meeting in Barcelona, Spain. Selected data from the SURVEYOR 1 and 2 studies demonstrated:
  • 97-98 percent SVR₁₂ with eight weeks of treatment in genotypes 1, 2 or 3 HCV patients without cirrhosis;
  • 100 percent SVR₁₂ with 12 weeks of treatment in difficult-to-treat genotype 3 patients with compensated cirrhosis (Child-Pugh A) new to therapy; and
  • 100 percent SVR₁₂ with 12 weeks of treatment in genotypes 4, 5 or 6 patients without cirrhosis; eight-week treatment duration is also being investigated in these genotypes in this ongoing study.
• A phase 1 clinical trial of EDP-494, Enanta’s cyclophilin inhibitor targeted to treat RAVs, DAA failures and other hard to treat populations, is ongoing and Enanta plans to initiate a proof-of-concept study next quarter.
• In April, Enanta Pharmaceuticals announced that the U.S. FDA had approved AbbVie’s supplemental New Drug Application for use of VIEKIRA PAK® without ribavirin in genotype 1b chronic hepatitis C patients with compensated cirrhosis (Child Pugh-A), which followed earlier approval in the European Union of AbbVie’s VIEKIRAX® + EXVIERA® for similar genotype 1b patients.
• Enanta is on track to initiate a phase 1 clinical trial in the second half of calendar 2016 with EDP-305, Enanta’s wholly-owned Farnesoid X Receptor (FXR) agonist candidate for non-alcoholic steatohepatitis (NASH) and Primary Biliary Cholangitis (PBC).

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 is currently focused on four disease targets: Hepatitis C Virus (HCV), Hepatitis B Virus (HBV), Non-alcoholic Steatohepatitis (NASH) and Respiratory Syncytial Virus (RSV).

Enanta has developed novel protease inhibitors and NS5A inhibitors that are members of the direct-acting-antiviral (DAA) inhibitor classes designed for use against the hepatitis C virus (HCV). Enanta’s protease inhibitors, developed through its collaboration with AbbVie, include paritaprevir, which is contained in AbbVie’s marketed DAA regimens for HCV, and ABT-493, Enanta’s second protease inhibitor, which AbbVie is developing in phase 3 studies in combination with ABT-530, AbbVie’s NS5A inhibitor. Enanta has also discovered a cyclophilin inhibitor, EDP-494, a novel, host-targeting mechanism for HCV, which is now in phase 1 clinical development, and EDP-305, an FXR agonist, which Enanta plans to advance into clinical development for NASH later in 2016.
