Enanta Pharmaceuticals Reports Financial Results for its Fiscal Third Quarter Ended June 30, 2018

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 third quarter ended June 30, 2018.

“Enanta continues to benefit from the increasing royalty income from AbbVie’s net sales of MAVYRET, the best-selling drug for hepatitis C, which is funding development of our wholly owned programs in RSV, NASH, PBC and HBV,” commented Jay R. Luly, Ph.D., President and Chief Executive Officer, Enanta. “With net sales of MAVYRET in the first half of calendar and royalty year 2018 reaching over $1.75 billion, our royalties on 50% of those sales have moved into higher royalty rate tiers this quarter. In addition, in RSV we have completed dosing our Phase 1 trial of EDP-938, and expect to report final results later this year.”

Fiscal Third Quarter Ended June 30, 2018 Financial Results

Total revenue for the three months ended June 30, 2018 was $57.3 million, compared to $7.5 million for the three months ended June 30, 2017. The increase in revenue was due to an increase in royalties earned on AbbVie’s worldwide net sales of MAVYRET™/MAVIRET™ (glecaprevir/pibrentasvir), in major markets. For the three months ended June 30, 2017, revenue consisted exclusively of royalties earned on AbbVie’s worldwide net sales of HCV regimens containing paritaprevir.

Research and development expenses totaled $28.5 million for the three months ended June 30, 2018, compared to $15.4 million for the three months ended June 30, 2017. 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 respiratory syncytial virus (RSV), non-alcoholic steatohepatitis (NASH) and primary biliary cholangitis (PBC), as well as research efforts in hepatitis B virus (HBV).

General and administrative expenses totaled $6.1 million for the three months ended June 30, 2018, compared to $5.2 million for the three months ended June 30, 2017. The increase in general and administrative expenses was primarily due to an increase in headcount.

Enanta recorded income tax expense of $3.7 million for the three months ended June 30, 2018, compared to an income tax benefit of $4.1 million for the three months ended June 30, 2017. During the three months ended June 30, 2018, income tax expense reflected the significant increase in pre-tax income during the quarter, offset by the impact of excess tax benefits from employee stock award activity. Enanta’s estimated annual effective tax rate for fiscal 2018 of 22.2 percent includes the impact of a non-cash revaluation charge against deferred tax assets to reflect the reduced federal corporate income tax rate as a result of the enactment of the U.S. Tax Cuts and Jobs Act in December 2017, during the first quarter of Enanta’s current fiscal year.

Net income for the three months ended June 30, 2018 was $20.3 million, or $0.97 per diluted common share, compared to a net loss of $8.4 million, or $(0.44) per diluted common share, for the corresponding period in 2017.

Enanta’s cash, cash equivalents and short-term and long-term marketable securities totaled $295.5 million at June 30, 2018. This compares to a total of $293.7 million at September 30, 2017. 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.

Development Programs and Business Review

Respiratory Syncytial Virus

• Preliminary Phase 1 results demonstrate that EDP-938 was generally safe and well tolerated over a broad range of single and multiple doses with good pharmacokinetic (PK) data. Final results will be presented in the fourth calendar quarter of 2018.
• A Phase 2 proof-of-concept challenge study in healthy adults inoculated with RSV is expected to begin in the fourth calendar quarter of 2018.

NASH and PBC

• Enrollment continues in the ARGON-1 study for non-alcoholic steatohepatitis (NASH), and in the INTREPID study for primary biliary cholangitis (PBC) patients. We expect enrollment to continue throughout the year and into 2019.

Hepatitis B Virus

• Enanta’s HBV program continues to move ahead and has generated promising inhibitors of the core protein. Enanta is targeting the selection of an HBV candidate in the fourth calendar quarter of 2018.

Forward Looking Statements
This press release contains forward-looking statements, including statements with respect to the prospects for AbbVie’s MAVYRET/MAVIRET regimen in HCV and Enanta’s resulting royalty revenues, as well as the prospects and timelines for advancement of Enanta’s earlier stage programs in NASH, PBC, RSV and HBV.
