WATERTOWN, Mass.--(BUSINESS WIRE)--Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a chemistry-driven biotechnology company dedicated to creating and developing small molecule drugs for viral infections and liver diseases, today reported financial results for its fiscal fourth quarter and year ended September 30, 2017.

Enanta’s cash, cash equivalents and short-term and long-term marketable securities totaled $293.7 million at September 30, 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.

“Enanta has made great progress this past year and has delivered on several key clinical and financial milestones,” stated Jay R. Luly, Ph.D., President and Chief Executive Officer of Enanta. “Enanta is on track this quarter to earn the final regulatory milestone in our eleven year HCV collaboration with AbbVie, which would mean we would have successfully earned all clinical and regulatory milestones under the collaboration. To date, this collaboration has provided us with a total of approximately $500 million to fund and advance our internal pipeline. With these resources, we expect to initiate two clinical studies by the end of 2017: a Phase 2 study of our lead FXR agonist EDP-305 in PBC, and a Phase 1 study of our direct-acting antiviral inhibitor EDP-938 for RSV.”

Fiscal Fourth Quarter and Year Ended September 30, 2017 Financial Results

Total revenue for the three months ended September 30, 2017 was $75.9 million, compared to $12.8 million for the three months ended September 30, 2016. For the twelve months ended September 30, 2017, total revenue was $102.8 million, compared to $88.3 million for the same period in 2016. The increase in revenue for the quarter was due to $65.0 million in milestone payments for the U.S. and EU approvals of AbbVie’s new HCV regimen under the tradenames MAVYRET™ and MAVIRET™, respectively. For the twelve months ending September 30, 2017, revenue also included $37.8 million in royalties earned on AbbVie’s worldwide net sales of HCV regimens containing paritaprevir or glecaprevir. For the 2016 twelve-month period, revenue consisted primarily of $57.7 million of royalty revenues earned on AbbVie’s worldwide net sales of HCV regimens containing paritaprevir, as well as a $30.0 million milestone payment for the reimbursement approval of one of those regimens, VIEKIRAX^®, in Japan in November 2015. 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 $16.5 million for the three months ended September 30, 2017, compared to $11.5 million for the three months ended September 30, 2016. For the twelve months ended September 30, 2017, research and development expenses totaled $57.5 million compared to $40.5 million for the same period in 2016. The increase in research and development expenses in both periods 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 $5.1 million for the three months ended September 30, 2017, compared to $4.4 million for the three months ended September 30, 2016. For the twelve months ended September 30, 2017, general and administrative expenses totaled $20.7 million, compared to $17.0 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 compensation expense driven by increased headcount. For the twelve-month period, the increase was due to increased headcount as well as achievement of milestones under existing performance-based equity awards.

Enanta recorded income tax expense of $18.4 million for the three months ended September 30, 2017 compared to an income tax benefit of $0.8 million for the same period in 2016. Enanta recorded income tax expense of $9.2 million for the year ended September 30, 2017 compared to income tax expense of $10.9 million for the same period in 2016. The Company’s effective tax rate for fiscal 2017 was approximately 34%.

Net income for the three months ended September 30, 2017 was $36.5 million, or $1.86 per diluted common share, compared to a net loss of $1.8 million, or $(0.09) per diluted common share, for the corresponding period in 2016. For the twelve months ended September 30, 2017, net income was $17.7 million, or $0.91 per diluted common share, compared to net income of $21.7 million, or $1.13 per diluted common share, for the corresponding period in 2016.

Development Program and Business Review

• On October 23, Enanta announced positive results from its Phase 1 clinical study of EDP-305, Enanta’s lead FXR agonist for non-alcoholic steatohepatitis (NASH) and primary biliary cholangitis (PBC). In this study of single ascending doses (SAD) and multiple doses at ascending dose levels per subject cohort (MAD), EDP-305 was generally safe and well tolerated over a broad range of single and multiple doses with pharmacokinetic (PK) data supporting once daily oral dosing. EDP-305 also exhibited strong engagement of the FXR receptor as evidenced by increased FGF19 levels and reduced C4 levels. These results support the ability to administer EDP-305 in future trials at doses that neither elicited clinically significant changes in lipids nor resulted in pruritus (itching).
• Enanta expects to initiate two clinical studies by the end of 2017: a Phase 2 clinical study of EDP-305 in patients with primary biliary cholangitis (PBC) and a Phase 1 study of respiratory syncytial virus (RSV) development candidate EDP-938 in healthy volunteers. A Phase 2 clinical study of EDP-305 in patients with NASH is expected to begin in early 2018.
• The U.S. Food and Drug Administration (FDA) has granted Enanta’s drug candidate EDP-305, an FXR agonist, Fast Track designation for the treatment of patients with primary biliary cholangitis.
• Bryan Goodwin, Ph.D., has recently joined Enanta as Vice President of Biology. Dr. Goodwin will provide senior leadership to the virology and NASH biology groups.
• During the quarter, Enanta received milestone payments of $65.0 million for the U.S. and European approvals of AbbVie’s new MAVYRET™/MAVIRET™ (glecaprevir/pibrentasvir) regimen. Glecaprevir, Enanta’s second protease inhibitor product, is part of this new HCV treatment regimen that will earn royalties for Enanta.
• On September 27, Enanta announced that AbbVie also received approval in Japan for MAVIRET™ (glecaprevir/pibrentasvir). Enanta will earn a $15.0 million milestone payment from AbbVie upon price reimbursement approval of MAVIRET™ in Japan, which is expected in the quarter ending December 31, 2017.

About Enanta
Enanta Pharmaceuticals has used its robust, chemistry-driven approach and drug discovery capabilities to become a leader in the discovery of small molecule drugs for the treatment of viral infections and liver diseases. Two protease inhibitors, paritaprevir and glecaprevir, discovered and developed through Enanta’s collaboration with AbbVie, have now been approved in jurisdictions around the world as part of AbbVie’s direct-acting antiviral (DAA) regimens for the treatment of hepatitis C virus (HCV) infection, including the U.S.-marketed regimens MAVYRET™ (glecaprevir/pibrentasvir) and VIEKIRA PAK^® (paritaprevir/ritonavir/ombitasvir/dasabuvir).

Royalties and milestone payments from the AbbVie collaboration are helping to fund Enanta’s research and development efforts, which 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).
