Reported Positive Topline Data from Phase 2 SPRINT Clinical Study of EDP-235, a 3CL Protease Inhibitor, in Development as an Oral, Once-Daily Treatment for COVID-19

•

Strengthened Balance Sheet Through the Sale of 54.5% of Future MAVYRET®/MAVIRET® Royalties for an Upfront Payment of $200 Million

•

On Track to Report Phase 1 Data of EDP-323, an L-Protein Inhibitor in Development as an Oral, Once-Daily Treatment for Respiratory Syncytial Virus, in June

•

Royalty Revenue for the Quarter was $17.8 Million

WATERTOWN, Mass., May 8, 2023 – Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a clinical-stage biotechnology company dedicated to creating small molecule drugs for viral infections, today reported financial results for its fiscal second quarter ended March 31, 2023.

“At Enanta, we are focused on transforming the lives of patients with curative therapies, by leveraging our previous successes in the development of small molecules and our deep understanding of virologic diseases,” said Jay R. Luly, Ph.D., President and Chief Executive Officer of Enanta Pharmaceuticals. “This vision is supported by positive topline data from our SPRINT Phase 2 study announced today. With EDP-235 and Enanta’s entire pipeline, our goal continues to be to develop cures for life-threatening viral infections. Looking ahead, we are also eager to advance our programs in respiratory syncytial virus with an upcoming data readout for EDP-323, our L-protein inhibitor in development as a once-daily oral treatment, next month. Further, the financial flexibility we now have with the additional funding from our royalty monetization allows us to continue to advance our robust pipeline.”

Fiscal Second Quarter Ended March 31, 2023 Financial Results

Total revenue for the three months ended March 31, 2023 was $17.8 million and consisted of royalty revenue from worldwide net sales of AbbVie’s hepatitis C virus (HCV) regimen MAVYRET®/MAVIRET® (glecaprevir/pibrentasvir), compared to $18.7 million for the three months ended March 31, 2022.

Research and development expenses totaled $43.5 million for the three months ended March 31, 2023, compared to $42.1 million for the three months ended March 31, 2022. The increase was primarily due to the timing of clinical trial expenses in our virology programs.

General and administrative expenses totaled $13.8 million for the three months ended March 31, 2023, compared to $10.5 million for the three months ended March 31, 2022. The increase was due to increased stock-related compensation expense and legal fees associated with our patent infringement suit against Pfizer.

Net loss for the three months ended March 31, 2023 was $37.7 million, or a loss of $1.79 per diluted common share, compared to a net loss of $33.6 million, or a loss of $1.63 per diluted common share, for the corresponding period in 2022.

Enanta’s cash, cash equivalents and short-term and long-term marketable securities totaled $225.1 million at March 31, 2023, before giving effect to its April 2023 sale of 54.5% of its ongoing MAVYRET®/MAVIRET® royalties from AbbVie for an upfront payment of $200 million from OMERS, one of Canada’s largest defined benefit pension plans. Enanta expects that its current cash, cash equivalents and marketable securities, as well as the royalty sale and Enanta’s continuing portion of cash from future royalty revenue, will be sufficient to meet the anticipated cash requirements of its existing business and development programs into calendar 2026.

Pipeline Updates

COVID-19 (SARS-CoV-2)

•

Today, Enanta announced positive topline data from SPRINT (SARS-Cov-2 PRotease INhibitor Treatment), a double-blind, placebo-controlled Phase 2 clinical trial of EDP-235, the company’s oral, 3CL protease inhibitor, in non-hospitalized, symptomatic adults with mild or moderate COVID-19 who were not at high risk for severe disease. In the trial, EDP-235 met the primary endpoint and was generally safe and well-tolerated. A dose-dependent improvement in symptoms was observed with EDP-235 treatment compared to placebo, which achieved statistical significance (p<0.05) in the 400mg treatment group at multiple time points, starting as early as one day after the first dose. In a prespecified population consisting of patients enrolled within 3 days of symptom onset, a statistically significant improvement was observed with EDP-235 at 400mg at all time points. While no difference was observed in time to improvement of 14 targeted COVID-19 symptoms, an analysis of a subset of these symptoms showed a 2-day shorter time to improvement in patients receiving EDP-235 400mg who were enrolled within 3 days of symptom onset (p<0.01). No effect on virologic endpoints as measured in the nose was detected due to the rapid viral decline in the placebo arm of this highly immunologically-experienced, standard risk population.

•

Enanta will continue to evaluate data from SPRINT and is focusing on partnership opportunities for Phase 3 and on the potential for a different Phase 2 study in acute or long COVID that could further demonstrate the efficacy of EDP-235.

•

Enanta is advancing a research program focused on the discovery and development of inhibitors of the SARS-CoV-2 papain-like protease (PLpro) for the oral treatment of COVID-19. The company continues to optimize inhibitors as it progresses this program forward to select a development candidate.

Respiratory Syncytial Virus (RSV)

•

Enanta is progressing a broad clinical program, aimed at targeting populations at high-risk for RSV, and is evaluating EDP-938, an N-protein inhibitor, with three ongoing clinical trials. EDP-938 is supported by data from a previous clinical challenge study showing that the compound significantly inhibited replication of RSV, the only published study to show such an effect for an N-inhibitor. EDP-938 also has a favorable and consistent safety profile.

Multiple ongoing studies include RSVPEDs, a Phase 2 randomized, double-blind, placebo-controlled study in hospitalized and non-hospitalized pediatric RSV patients; RSVHR, a Phase 2b randomized, double-blind, placebo-controlled study in adults with acute RSV infection who are at high risk of complications, including the elderly and/or those with congestive heart failure, chronic obstructive pulmonary disease or asthma; and RSVTx, a Phase 2b, randomized, double-blind, placebo-controlled study in adult hematopoietic cell transplant recipients with acute RSV infection and symptoms of upper respiratory tract infection.

These three studies are expected to continue through 2023. Enanta is monitoring RSV epidemiology to determine the impact on trial enrollment and timing for data readouts.

•

Enanta is on track to report topline Phase 1 data in June from its ongoing study of EDP-323, a novel, oral, direct-acting antiviral selectively targeting the RSV L-protein. This double-blind, placebo-controlled, first-in-human study is designed to enroll healthy subjects to assess EDP-323's safety, tolerability, and pharmacokinetics (PK). EDP-323 has the potential to be used alone or in combination with EDP-938 to potentially broaden the addressable patient populations or the treatment window.

In April, at ECCMID, Enanta reported preclinical data highlighting EDP-323’s favorable preclinical PK properties, excellent bioavailability with low plasma clearance, and favorable target tissue distribution, supporting a once-daily, oral-dosing regimen for RSV.

Human Metapneumovirus (hMPV)/RSV

•

Enanta’s research program targeting both hMPV and RSV with a single agent, which the company refers to as a dual inhibitor, is ongoing. In preclinical studies, Enanta’s prototype dual inhibitor maintained nanomolar activity against multiple genotypes and strains of hMPV and RSV in a range of cell types. Further, the dual inhibitor potently inhibited replication of both hMPV and RSV in a dose-dependent manner in mouse models of the respective viruses, demonstrating significant reductions in viral load of each virus. Enanta expects to select a dual hMPV/RSV inhibitor clinical candidate in the fourth quarter of 2023.

Hepatitis B Virus (HBV)

•

Enanta remains focused on identifying additional compounds externally with different mechanisms of action to combine with EDP-514, its potent core inhibitor, and a nucleoside reverse transcriptase inhibitor. EDP-514 has displayed a good safety profile and robust antiviral activity in multiple HBV patient populations, with significant declines in HBV DNA among the best published to date for core inhibitors.

Corporate

•

In April, Enanta strengthened its balance sheet with the sale to OMERS of 54.5% of Enanta’s future royalty payments from AbbVie Inc. on worldwide sales of MAVYRET/MAVIRET. The upfront purchase price paid to Enanta was $200 million. OMERS right to receive royalty payments is based on net sales of the product beginning in July 2023 through June 2032, with total payments capped at 1.42 times the purchase price. Enanta’s retains 45.5% of all royalties until the cap is hit, at which point 100% of all further royalties revert to Enanta.
