Item 8.01 Other Events

On March 27, 2024, the Company announced results of the body composition analysis from its 48-week MOMENTUM Phase 2 obesity trial of pemvidutide.

As announced on November 30, 2023, the trial enrolled 391 subjects with obesity or overweight with at least one co-morbidity and without diabetes. Subjects 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. The 1.2 mg and 1.8 mg doses were administered without dose titration, while a short 4-week titration period was employed for the 2.4 mg dose. At baseline, subjects had a mean age of approximately 50 years, mean body mass index (BMI) of approximately 37 kg/m2 and mean body weight of approximately 104 kg. Approximately 75% of subjects were female.

The body composition analysis showed that 74.5% of weight loss was derived from adipose tissue and only 25.5% from lean mass, comparable to the effects historically associated with weight loss from diet and exercise programs.

Exhibit 99.1

Altimmune Announces Positive Lean Mass Preservation Data for Pemvidutide and Reports Fourth Quarter and Full Year 2023 Financial Results

Body composition study showed lean mass preservation, with only 25.5% of weight loss derived from lean mass

Enrollment ongoing in IMPACT Phase 2b trial of pemvidutide in Metabolic Dysfunction-Associated Steatohepatitis (MASH), with topline 24-week data expected Q1 2025

Preclinical study results showed a direct anti-fibrotic effect of pemvidutide in a non-steatotic model of liver fibrosis

Cash, cash equivalents and short-term investments of $198.0 million at December 31, 2023

Webcast to be held today, March 27, 2024, at 8:30 am ET

GAITHERSBURG, MD – March 27, 2024 – Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided a business update.

“We are extremely pleased with the results of the body composition analysis from our recently completed MOMENTUM 48-week Phase 2 obesity trial of pemvidutide. Our data show that 74.5% of weight loss was derived from adipose tissue and only 25.5% from lean mass, comparable to the effects historically associated with weight loss from diet and exercise programs,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “Based on compelling weight loss, a clean safety profile, robust reductions in serum lipids and blood pressure, and now preservation of lean mass observed in our clinical trials, we believe that pemvidutide has the potential to distinguish itself broadly from other therapies for the treatment of obesity. We also remain excited about the outcome of our ongoing IMPACT Phase 2b MASH trial with topline 24-week data on the key endpoints of MASH resolution or fibrosis improvement anticipated in the first quarter of 2025. The results from a recently completed preclinical study demonstrating direct anti-fibrotic activity of pemvidutide only adds to our optimism about achieving a positive outcome in this trial.”

“Preservation of lean mass during weight loss is critical, since excessive loss of lean mass has been associated with negative outcomes, such as sarcopenia and bone fractures, especially in women and the elderly,” said Scott Harris, Chief Medical Officer, Altimmune. “There is a growing appreciation that the quality of weight loss is as important as the quantity of weight loss. Given these new body composition data, the robust reductions in serum lipids, and the class-leading reduction of hepatic fat content, we believe that pemvidutide, if approved, could stand out as an attractive option for weight loss and weight maintenance.”

Recent Highlights and Anticipated Milestones:

Pemvidutide

Positive lean mass preservation in body composition analysis from MOMENTUM trial
oBody composition analysis from MOMENTUM showed only 25.5% of weight loss derived from lean mass, with 74.5% of weight loss from adipose tissue, comparable to the effects historically associated with diet and exercise.
oComplete analysis of the data to be presented at an upcoming scientific meeting.

Positive top-line data readout from MOMENTUM 48-week Phase 2 obesity trial in November 2023
oAchieved mean weight loss of 15.6% on 2.4 mg dose of pemvidutide at week 48, with weight loss continuing at the end of treatment.
oOver 30% of subjects achieved 20% or more weight loss on the 2.4 mg dose.
oRobust reductions of triglycerides (55.8%), total cholesterol (20.0%) and LDL cholesterol (17.4%) on 2.4 mg dose in patients with elevated baseline lipids.
oUp to 78.6% of subjects with excess liver fat normalized their liver fat content.
oImprovements in blood pressure without imbalances in cardiac events, arrhythmias or clinically meaningful increases in heart rate.

Enrollment ongoing in IMPACT biopsy-driven Phase 2b MASH trial
oThe FDA granted Fast Track designation to pemvidutide for the treatment of MASH.
oApproximately 190 subjects with and without diabetes are being randomized 1:2:2 to 1.2 mg, 1.8 mg pemvidutide or placebo.
oThe key endpoints are MASH resolution or fibrosis improvement after 24 weeks of treatment, with subjects to be followed for an additional 24 weeks of dosing for assessment of safety and additional biomarker responses.
oTop-line results after 24 weeks of treatment are expected in the first quarter of 2025.

Demonstration of the direct anti-fibrotic effects of pemvidutide in a preclinical model of hepatic fibrosis
oSignificant improvement observed in a model of chemically-induced hepatic fibrosis after 14 days of treatment with pemvidutide.
oThe model excluded the effects of liver fat reduction, providing evidence for a direct effect of pemvidutide in reducing liver fibrosis.

Demonstration of improved cholesterol elimination in a preclinical model of dyslipidemia
oPemvidutide stimulated reverse cholesterol transport and increased cholesterol elimination.
oThese data provide evidence for a potential additional mechanism of reducing cardiovascular risk beyond the effects of pemvidutide on serum lipids and liver fat content.

HepTcellTM

The Phase 2 clinical trial evaluating the efficacy of HepTcell in reducing virological markers in patients chronically infected with the hepatitis B virus has been completed. The overall response in the trial was deemed to be insufficient to warrant further advancement. As a result, any further development related to HepTcell has been stopped.

Financial Results for the Three Months Ended December 31, 2023

Altimmune had cash, cash equivalents and short-term investments totaling $198.0 million as of December 31, 2023.
Research and development expenses were $16.9 million for the three months ended December 31, 2023, compared to $19.2 million in the same period in 2022. The expenses for the quarter ended December 31, 2023 included $10.3 million in direct costs related to development activities for pemvidutide and $1.1 million in direct costs related to development activities for HepTcell.
General and administrative expenses were $4.3 million for the three months ended December 31, 2023, compared to $3.8 million in the same period in 2022. The increase was primarily due to $0.3 million increase in professional fees and $0.2 million increase in stock compensation.
Impairment loss on intangible asset of $12.4 million was recognized during the three months ended December 31, 2023 related to the acquired In-Process Research and Development asset associated with HepTcell. The overall response in the Phase 2 trial was deemed to be insufficient to warrant further advancement. As a result, any further development related to HepTcell has been stopped.
Interest income for the three months ended December 31, 2023 was $2.0 million as compared to $1.5 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 December 31, 2023 was $31.6 million, or $0.54 net loss per share, compared to a net loss of $21.7 million, or $0.43 net loss per share, in the same period in 2022. The net loss for 2023 included the $12.4 million noncash impairment charge described above.

About Pemvidutide

Pemvidutide is a novel, investigational, peptide-based GLP-1/glucagon dual receptor agonist in development for the treatment of obesity and MASH. 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 and serum lipids. In clinical trials, once-weekly pemvidutide has shown compelling weight loss, robust reductions in triglycerides, LDL cholesterol, liver fat content and blood pressure with a clean safety profile to date. The U.S. FDA has granted Fast Track designation to pemvidutide for the treatment of MASH. Pemvidutide has recently completed the MOMENTUM Phase 2 obesity trial and is being studied in the IMPACT Phase 2b MASH trial.

About Altimmune

Altimmune is a clinical-stage biopharmaceutical company focused on developing innovative next-generation peptide-based therapeutics. The Company is developing pemvidutide, a GLP-1/glucagon dual receptor agonist for the treatment of obesity and MASH. For more information, please visit www.altimmune.com.
