Altimmune Announces Third Quarter 2023 Financial Results and Provides a Business Update

Top-line 48-week results from the MOMENTUM Phase 2 obesity trial expected Q4 2023

Pemvidutide granted Fast Track designation for the treatment of non-alcoholic steatohepatitis (NASH)

Top-line results from the Phase 2 trial of HepTcell^TM in chronic hepatitis B (CHB) expected Q1 2024

Webcast to be held today, November 7, 2023, at 8:30 am EST

GAITHERSBURG, Maryland – November 7, 2023 – Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the three months ended September 30, 2023, and provided a business update.

“The next few months will be important as we receive the data from our 48-week MOMENTUM trial of pemvidutide in subjects with obesity as well as the results of our Phase 2 trial of HepTcell in CHB,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “The rapidly expanding obesity market needs differentiated products that address not only excess body weight, but also risk factors for cardiovascular comorbidities, including elevated LDL-cholesterol and excess liver fat. We also were very pleased to receive Fast Track designation for our pemvidutide program in NASH, which demonstrates the unmet need for this critical liver disease. We believe that our liver fat reduction is class-leading and could result in unprecedented reductions of fibrosis and measures of NASH.”

Recent Highlights and Anticipated Milestones

Pemvidutide

● Top-line data readout from 48-week MOMENTUM Phase 2 obesity trial expected in Q4 2023

o Patient dosing (last subject last dose) was completed in September 2023.

o Dr. Louis Aronne, Professor of Metabolic Research and Professor of Clinical Medicine, Weil Cornell Medical School, a leading authority in obesity and obesity clinical trials, is serving as the Principal Investigator.

o 391 subjects with obesity or overweight and without diabetes were randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 48 weeks in conjunction with diet and exercise.

o In an interim 24-week data readout in March 2023, subjects receiving pemvidutide achieved robust reductions in body weight, waist circumference, serum lipids and blood pressure without arrhythmias, clinically meaningful heart rate increases or other safety signals.

o Top-line data readout at 48 weeks will include subject disposition, weight loss, serum lipids, vital signs, adverse events and glycemic control.

● Enrollment commenced in IMPACT Phase 2b NASH trial

o Informed by the positive results of the Phase 1b randomized, placebo-controlled trials of pemvidutide in subjects with non-alcoholic fatty liver disease (NAFLD), the FDA granted pemvidutide Fast Track designation for the treatment of NASH.

o This Phase 2b biopsy-driven NASH trial is being conducted at approximately 60 sites in the U.S., with Dr. Stephen Harrison, Medical Director, Pinnacle Research, and Adjunct Professor of Medicine, Oxford University, serving as the principal investigator.

o Approximately 190 subjects with and without diabetes are planned to be randomized 1:2:2 to 1.2 mg, 1.8 mg pemvidutide or placebo.

o The key endpoints will be NASH resolution and fibrosis improvement after 24 weeks of treatment, with subjects followed for an additional 24 weeks for assessment of safety and additional biomarker responses.

o Top-line results after 24 weeks of treatment are expected in the first quarter of 2025.

HepTcell^TM

● Top-line data from Phase 2 clinical trial expected in Q1 2024

o Themulticenter clinical trial, which is being conducted at 26 sites in North America, Europe and Southeast Asia, enrolled approximately 80 previously untreated subjects with inactive CHB and low levels of hepatitis B surface antigen (HBsAg).

o Subjects were randomized 1:1 to HepTcell or placebo to receive six monthly administrations.

o The primary endpoint is virological response, defined as a 1-log or greater reduction or clearance of HBsAg; secondary endpoints include changes in the levels of hepatitis B virus (HBV) DNA, pre-genomic RNA and other markers of virologic response.

o Data readout is expected in the first quarter of 2024 after all subjects complete the 6-month course of treatment.

Financial Results for the Three Months Ended September 30, 2023

● Cash, cash equivalents and short-term investments totaled $140.8 million as of September 30, 2023.

● Research and development expenses were $18.4 million for the three months ended September 30, 2023, compared to $20.3 million in the same period in 2022. The expenses for the quarter ended September 30, 2023 included $10.4 million in direct costs related to development activities for pemvidutide and $1.6 million in direct costs related to development activities for HepTcell.

● General and administrative expenses were consistent period-over-period at $4.5 million for the three months ended September 30, 2023 and 2022.

● Interest income for the three months ended September 30, 2023 was $1.9 million as compared to $1.1 million in the same period in 2022, primarily due to an increase in interest income earned on cash equivalents and short-term investments.

● Net loss for the three months ended September 30, 2023 was $20.7 million, or $0.39 net loss per share, compared to a net loss of $23.5 million, or $0.48 net loss per share, in the same period in 2022.

About Pemvidutide

Pemvidutide is a novel, investigational, peptide-based GLP-1/glucagon dual receptor agonist in development for the treatment of obesity and NASH. Activation of the GLP-1 and glucagon receptors is believed to mimic the complementary effects of diet and exercise on weight loss, with GLP-1 suppressing appetite and glucagon increasing energy expenditure. Glucagon is also recognized as having direct effects on hepatic fat metabolism, leading to rapid reductions in levels of liver fat. Pemvidutide incorporates the EuPort^TM domain, a proprietary technology that increases its serum half-life for weekly dosing while likely slowing the entry of pemvidutide into the bloodstream, which may improve its tolerability.

About HepTcell

HepTcell is a novel, investigational, immunotherapeutic comprised of nine synthetic peptides representing conserved T-cell epitopes on key HBV antigens formulated with IC31®, a TLR9-based adjuvant from Valneva SE. The HBV-directed peptides are designed to drive T cell responses against all HBV genotypes towards a functional cure for chronic HBV in patients of diverse genetic backgrounds.

About Altimmune

Altimmune is a clinical-stage biopharmaceutical company focused on developing innovative next-generation therapeutics for the treatment of patients with liver diseases and obesity. The Company’s lead product candidate, pemvidutide, is a GLP-1/glucagon dual receptor agonist that is being developed for the treatment of obesity and NASH. In addition, Altimmune is developing HepTcell^TM, an immunotherapeutic designed to achieve a functional cure for CHB. For more information, please visitwww.altimmune.com.
