Enanta Pharmaceuticals Reports Financial Results for its Fiscal Third Quarter Ended June 30, 2019

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, 2019.

“Enanta executed on key clinical milestones during the past few months, the most significant being the completion of a successful Phase 2a challenge study of EDP-938 for RSV. In addition, we recently initiated a Phase 1 study of EDP-514, our lead candidate for the treatment of HBV,” commented Jay R. Luly, Ph.D., Enanta President and CEO. “Our pipeline is maturing, and we now have clinical studies ongoing with three compounds, all of which have been granted Fast Track designation.”

Fiscal Third Quarter Ended June 30, 2019 Financial Results

Total revenue of $44.4 million for the three months ended June 30, 2019 consisted of royalty revenue derived primarily from worldwide net sales of AbbVie’s hepatitis C virus (HCV) regimen MAVYRET™/MAVIRET™. For the three months ended June 30, 2018, total revenue was $57.3 million, which consisted of royalty revenue earned on AbbVie’s global net sales of its HCV regimens. AbbVie has stated that the decrease in royalty revenue in 2019 was mainly driven by lower treated patient volumes in select international markets.

Research and development expenses increased to $34.5 million for the three months ended June 30, 2019, compared to $28.5 million for the three months ended June 30, 2018, primarily due to increased clinical costs associated with the progression of Enanta’s wholly-owned clinical programs in respiratory syncytial virus (RSV), non-alcoholic steatohepatitis (NASH), primary biliary cholangitis (PBC), and hepatitis B virus (HBV).

General and administrative expenses totaled $6.2 million for the three months ended June 30, 2019, compared to $6.1 million for the three months ended June 30, 2018.

Enanta recorded an income tax benefit of $0.9 million for the three months ended June 30, 2019 compared to income tax expense of $3.7 million for the same period in 2018. The income tax benefit was driven by a federal tax benefit associated with foreign derived royalty income from our AbbVie collaboration agreement.

Net income for the three months ended June 30, 2019 was $7.0 million, or $0.33 per diluted common share, compared to net income of $20.3 million, or $0.97 per diluted common share, for the corresponding period in 2018.

Enanta’s cash, cash equivalents and marketable securities totaled $389.2 million at June 30, 2019. This compares to a total of $325.1 million at September 30, 2018. Enanta expects that its current cash, cash equivalents and marketable securities, as well as its continuing royalty revenue, 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

EDP-938, N-Protein Inhibitor for Respiratory Syncytial Virus (RSV):

• In June, Enanta announced topline results from its Phase 2a human challenge study of EDP-938 in healthy adults infected with respiratory syncytial virus (RSV). Data demonstrated EDP-938 achieved highly statistically significant (p<0.001) reductions in viral load and in resolution of clinical symptoms compared to placebo.
• Enanta’s first Phase 2b study in adult outpatients with RSV infection is planned to begin by the end of calendar 2019.

EDP-305, FXR Agonist for Non-Alcoholic Steatohepatitis (NASH):

• Topline data from the Phase 2a ARGON-1 study in NASH are expected by the end of the third quarter of calendar 2019.
• Enanta also expects to identify a follow-on FXR clinical candidate in calendar 2019.

EDP-514, Core Inhibitor for Hepatitis B Virus (HBV):

• In July, Enanta announced that it had initiated part 1 of a Phase 1a/1b clinical study of EDP-514. Part 1 of the randomized, double-blind, placebo-controlled study is designed to evaluate the safety, tolerability and pharmacokinetics (PK) of single ascending doses (SAD) and multiple ascending doses (MAD) of EDP-514 in healthy subjects. Part 2 will then evaluate the antiviral activity of EDP-514 in nucleos(t)ide-reverse-transcriptase (NUC)-suppressed patients with chronic HBV infection.

Hepatitis C Virus (HCV) collaboration with AbbVie:

• AbbVie announced that the European Commission has granted marketing authorization to AbbVie for MAVIRET™ (glecaprevir/pibrentasvir) to shorten once-daily treatment duration from 12 to 8 weeks in treatment-naïve, chronic hepatitis C (HCV) patients with compensated cirrhosis and genotype (GT)1, 2, 4, 5, or 6 infection.
• Glecaprevir, is one of the two direct-acting antivirals (DAAs) in MAVIRET and is Enanta’s second protease inhibitor developed and commercialized by AbbVie.
