WATERTOWN, Mass., Nov. 20, 2023 – Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a clinical-stage biotechnology company dedicated to creating small molecule drugs with an emphasis on treatments for viral infections, today reported financial results for its fiscal fourth quarter and year ended September 30, 2023.

“Throughout fiscal 2023, Enanta remained focused on advancing our two RSV clinical stage programs of best-in-class antivirals with different mechanisms of action. We are pleased to announce the initiation of our Phase 2a challenge study of EDP-323, an L-protein inhibitor, in development as an oral, once-daily treatment for RSV, and look forward to reporting data in the third quarter of 2024,” said Jay R. Luly Ph.D., President and Chief Executive Officer of Enanta Pharmaceuticals. “Further, we are advancing RSVPEDs and RSVHR, our ongoing Phase 2 trials of EDP-938, our N-protein inhibitor, with a data readout from at least one of these studies in the third quarter of 2024, assuming this winter is a normal Northern Hemisphere RSV season. We have also made important adjustments to significantly reduce our 2024 spending and extend our cash runway through fiscal 2027. As a result, we are well positioned financially as we look forward to readouts across our RSV pipeline in 2024 and advancements in new non-virology programs.”

Fiscal Fourth Quarter and Year Ended September 30, 2023 Financial Results

Total revenue was $18.9 million for the three months ended September 30, 2023, which consisted of royalty revenue derived from worldwide net sales of AbbVie’s hepatitis C virus (HCV) regimen MAVYRET®/MAVIRET®, compared to royalty revenue of $20.3 million for the three months ended September 30, 2022. For the twelve months ended September 30, 2023, total revenue was $79.2 million compared to $86.2 million for the same period in 2022. The decrease in the quarter and in year-over-year revenue is due to a decline in AbbVie’s sales of MAVYRET®/MAVIRET®.

Beginning with the quarter ended September 30, 2023, 54.5% of Enanta’s ongoing royalties from AbbVie’s net sales of MAVYRET®/MAVIRET® are being paid to OMERS, one of Canada’s largest defined benefit pension plans, pursuant to a royalty sale transaction in April 2023. For financial reporting purposes, the transaction was treated as debt, with the upfront purchase payment of $200.0 million recorded as a liability. Enanta will continue to record 100% of the royalty earned as revenue and will then amortize the debt liability proportionally as 54.5% of the cash royalty payments are paid to OMERS, until a cap of 1.42 times the purchase payment is met, after which point 100% of the cash royalty payments will be retained by Enanta. Non-cash interest expense was $3.2 million for the three months ended September 30, 2023 and $5.1 million for the twelve months ended September 30, 2023.

Research and development expenses were $36.2 million for the three months ended September 30, 2023, compared to $34.8 million for the three months ended September 30, 2022. The increase was due to the timing of clinical trial costs, offset by a decrease in preclinical and manufacturing costs. For the twelve months ended

September 30, 2023, research and development expenses were $163.5 million compared to $164.5 million in 2022.

General and administrative expenses totaled $13.8 million for the three months ended September 30, 2023, compared to $12.6 million for the three months ended September 30, 2022. For the twelve months ended September 30, 2023, general and administrative expenses were $52.9 million compared to $45.5 million in 2022. The increases in both periods were primarily due to an increase in legal fees related to the company's patent infringement suit against Pfizer.

Other income, net, totaled $4.7 million for the three months ended September 30, 2023, compared to $0.7 million for the three months ended September 30, 2022. For the twelve months ended September 30, 2023, other income, net, totaled $11.4 million compared to $1.7 million in 2022. The increases in both periods were primarily due to an increase in investment income due to an increase in Enanta’s average invested cash balance from the receipt in April 2023 of $200 million from the sale of the company’s MAVYRET®/MAVIRET® royalty, as well as increases in interest rates year over year.

Enanta recorded an income tax benefit of $1.4 million for the three months ended September 30, 2023, compared to income tax expense of less than $0.1 million for the three months ended September 30, 2022. Enanta recorded income tax expense of $2.8 million for the twelve months ended September 30, 2023, compared to an income tax benefit of $0.4 million for the three months ended September 30, 2022. Despite recording a loss before taxes during the twelve months ended September 30, 2023, Enanta recorded tax expense driven by the receipt of the $200.0 million from the royalty sale agreement, which is treated as income for Federal and State income tax purposes. This taxable income and its related income tax expense was substantially offset by net operating loss carryforwards, research and development tax credit carryforwards and a deduction for foreign derived intangible income.

Net loss for the three months ended September 30, 2023, was $28.1 million, or a loss of $1.33 per diluted common share, compared to a net loss of $26.3 million, or a loss of $1.27 per diluted common share, for the corresponding period in 2022. For the twelve months ended September 30, 2023, net loss was $133.8 million, or a loss of $6.38 per diluted common share, compared to a net loss of $121.8 million, or loss of $5.91 per diluted common share for the corresponding period in 2022.

Enanta’s cash, cash equivalents and marketable securities totaled $370.0 million at September 30, 2023. Enanta expects that its current cash, cash equivalents and short-term marketable securities, as well as its continuing retained portion of royalty revenue, will continue to be sufficient to meet the anticipated cash requirements of its existing business and development programs through fiscal 2027.

Pipeline Update and Business Review

Virology

RSV

•

Enanta is progressing multiple clinical programs aimed at treating populations at high-risk for serious outcomes from RSV infection, and is evaluating EDP-938, an N-protein inhibitor, with two ongoing Phase 2 clinical trials, RSVPEDS and RSVHR.

RSVPEDs is a Phase 2 randomized, double-blind, placebo-controlled study in hospitalized and non-hospitalized pediatric RSV patients. The study, which will enroll approximately 90 patients aged 28 days to 36 months, is being conducted in two parts. Because this is the first time the drug is being dosed in pediatrics, the objective of the first part of the study is to evaluate the safety and pharmacokinetics of EDP-938 in multiple ascending doses to select the optimal dose for each age group. The second part of the study will evaluate the antiviral activity of EDP-938 at the selected dose, and symptom scores will be assessed throughout the treatment duration. This part is designed as a small cohort to show a trend toward improved virology metrics for EDP-938 compared to placebo and to give confidence to move forward efficiently into registrational studies.

RSVHR is a Phase 2b randomized, double-blind, placebo-controlled study in approximately 180 adults with RSV infection who are at high risk of complications, including the elderly and those with congestive heart failure, chronic obstructive pulmonary disease or asthma. The primary endpoint of RSVHR is time to resolution of RSV lower respiratory tract disease symptoms as assessed by the Respiratory Infection Intensity and Impact Questionnaire (RiiQ™) symptom scale. Secondary endpoints include additional clinical efficacy measures and antiviral activity compared to placebo, pharmacokinetics, and safety of EDP-938.

RSVTx, a Phase 2b, randomized, double-blind, placebo-controlled study in adult hematopoietic cell transplant recipients with RSV infection and symptoms of upper respiratory tract infection, was discontinued in September and resources were reallocated to the enrollment and completion of the other ongoing Phase 2 RSV trials.

Enanta expects to complete enrollment in one or both of its ongoing Phase 2 studies of EDP-938 and to report data in the third quarter of 2024, assuming this winter is a normal pre-pandemic RSV season in the Northern Hemisphere. Enanta has expanded its global footprint and has over 75 sites across 15 countries for RSVPEDs and over 130 sites across 16 countries for RSVHR.

In October, Enanta presented data at IDWeekTM 2023 highlighting EDP-938’s high barrier to the development of clinical resistance as demonstrated in the human challenge study. This is in contrast to the lower barrier to resistance that has been observed for other mechanisms, thereby supporting further development of this first-in-class N-protein inhibitor.

•

Enanta today announced the initiation of a Phase 2a human challenge study of EDP-323, an oral, L-protein inhibitor in development for the treatment of RSV. The advancement of EDP-323 into a challenge study is supported by positive Phase 1 data which demonstrated favorable safety, tolerability, and pharmacokinetics (PK) supportive of once-daily dosing, with good exposure multiples. In this randomized, double-blind, placebo-controlled, human challenge study, up to 114 healthy adult subjects will be infected with RSV-A Memphis 37b virus. Primary and secondary outcome measures include safety, changes in viral load measurements and changes in baseline symptoms. Enanta plans to report data from this Phase 2a study in the third quarter of 2024.

In September, Enanta presented data for EDP-323 at the 9th European Scientific Working Group on Influenza (ESWI) Conference. These data detailed the positive results observed in the Phase 1 study of healthy subjects.

•

Enanta hosted an RSV Key Opinion Leader event in October which highlighted the ongoing need for RSV treatments despite the availability of new vaccines and prophylactic monoclonal antibodies. Guest speakers included Jaime Fergie, MD, FAAP, FIDSA, FSHEA, Medical Director of the Global Institute for Hispanic Health, Professor of Pediatrics at Texas A&M University, and Director of Infectious Diseases at Driscoll Children’s Hospital in Texas; and Tom Wilkinson, MA (Cantab), MBBS, PhD, FRCP, FERS, Professor of Respiratory Medicine and Associate Dean at the University of Southampton and a member of the Faculty of Medicine at Southampton General Hospital, United Kingdom.

COVID-19 (SARS-CoV-2)

•

Enanta plans to pursue any future COVID-19 efforts in the context of a collaboration, including the development of EDP-235, an oral, once-daily, Phase 3 ready 3CL protease inhibitor which has been granted Fast Track designation by the FDA.

Human Metapneumovirus (hMPV)/RSV

•

Enanta paused development of its research program targeting both hMPV and RSV with a single agent. Despite promising preclinical data, the company does not plan to move a third RSV candidate into the clinic as long as EDP-938 and EDP-323 continue to progress.

Hepatitis B Virus (HBV)

•

Enanta continues to seek an additional mechanism for development in a combination regimen with a nucleoside reverse transcriptase inhibitor and EDP-514, its potent core inhibitor which has Fast Track designation from the FDA, as a functional cure for HBV.

Non-Virology

•

Enanta is advancing discovery programs focused on non-virology indications that have a high unmet need and leverage the company’s expertise in preclinical small molecule drug discovery and development. The company will announce new therapeutic programs beginning in early 2024.
