ALT Altimmune Inc

Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the third quarter ended September 30, 2024, and provided a business update.

“In the third quarter, we reached several important milestones, most notably the completion of enrollment in the Phase 2b IMPACT trial of pemvidutide in MASH, positioning us to report top-line efficacy data in the second quarter of 2025,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “Further, we successfully completed our End-of-Phase 2 meeting with the FDA for the pemvidutide Phase 3 obesity program, gaining agreement on the design of the pivotal studies as well as the measures of efficacy and safety.”

Dr. Garg continued, “The Phase 3 program is designed to leverage the key attributes of pemvidutide, including the effects of balanced GLP-1/glucagon dual agonism in subjects with overweight and obesity. The program will include four pivotal trials with a primary efficacy endpoint of weight loss and will evaluate the effects of pemvidutide on principal co-morbidities of obesity, including elevated serum lipids and excess liver fat. The program will also assess the preservation of lean mass and its impact on subjects at risk for loss of physical function and other complications of sarcopenia.”

“At the 60th Annual Meeting of the European Association for the Study of Diabetes, we presented compelling data from our Phase 2 MOMENTUM trial of pemvidutide in obesity, which highlighted its class-leading preservation of lean mass and preferential reduction in visceral adipose tissue, both of which are important differentiators for pemvidutide,” said Scott Harris, M.D., Chief Medical Officer of Altimmune. “We also remain on-track to submit an IND application this quarter for the first of up to three additional indications for pemvidutide, with the trial expected to initiate in the first half of 2025.”

Dr. Garg concluded, “The data we have generated to date, coupled with the multiple key inflection points on the horizon, give us confidence that 2025 will be a transformational year for pemvidutide, and for Altimmune.”

Recent Highlights and Anticipated Milestones:

Metabolic Dysfunction-Associated Steatohepatitis (MASH):

• The Company completed patient enrollment in IMPACT, a biopsy-driven Phase 2b trial of pemvidutide in MASH
  • The IMPACT trial is evaluating the efficacy and safety of pemvidutide in approximately 190 subjects with biopsy-confirmed MASH.
  • With a successful readout from IMPACT, pemvidutide would be the first MASH therapy to achieve both fibrosis improvement and significant weight loss at 24 weeks of treatment.
  • Top-line efficacy data is expected in Q2 2025.

Obesity:

• Completed End-of-Phase 2 Meeting for the obesity program with the FDA
  • Agreement was reached on the plan for four Phase 3 clinical trials that leverage the key attributes of pemvidutide including balanced GLP-1/glucagon dual agonism.
  • Each of the four studies is designed to assess the ability of pemvidutide treatment to drive meaningful weight loss and address co-morbidities in specific subpopulations of patients with overweight or obesity.
  • Data from these studies are expected to form the basis for a registrational package to support FDA approval of pemvidutide in obesity.
• The Company presented data from a body composition sub-study from the Phase 2 MOMENTUM trial at the 60th Annual Meeting of the European Association for the Study of Diabetes (EASD)
  • In an MRI evaluation of subjects with overweight and obesity treated with pemvidutide for 48 weeks, the lean loss ratio was 21.9%.
  • Lean mass preservation was greater in subjects aged 60 years and older, in whom the lean loss ratio was further reduced to 19.9%.
  • In addition to the preservation of lean mass, visceral adipose tissue (VAT) was reduced by 28.3% in the 2.4mg cohort at Week 48. Reduction of VAT is important as VAT is closely associated with cardiovascular risk.

Additional Indications for Pemvidutide:

• The Company plans to submit IND applications for pemvidutide in up to three additional indications
  • The first of these IND applications will be submitted in Q4 2024, with remaining IND applications expected to be submitted in the first half of 2025.
  • Preparations for the first trial are underway, with initiation planned for H1 2025.

Corporate Update:

• On November 11, 2024, the Company announced the appointment of life sciences industry veteran Greg Weaver as Chief Financial Officer

Financial Results for the Three Months Ended September 30, 2024:

• Altimmune had cash, cash equivalents and short-term investments totaling $139.4 million on September 30, 2024.
• Research and development expenses were $19.8 million for the three months ended September 30, 2024, compared to $18.4 million in the same period in 2023. The expenses for the quarter ended September 30, 2024, included $12.4 million in direct costs related to development activities for pemvidutide and $0.8 million in direct costs related to additional research and discovery projects.
• General and administrative expenses were $5.0 million for the three months ended September 30, 2024, compared to $4.5 million in the same period in 2023. The increase was primarily due to a $0.4 million increase in professional fees.
• Interest income was consistent period-over-period at $1.9 million for each of the three months ended September 30, 2024 and 2023.
• Net loss for the three months ended September 30, 2024, was $22.8 million, or $0.32 net loss per share, compared to a net loss of $20.7 million, or $0.39 net loss per share, in the same period in 2023.

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, which is believed to lead to rapid reductions in levels of liver fat and serum lipids. In clinical trials to date, once-weekly pemvidutide has demonstrated compelling weight loss with class-leading lean mass preservation, and robust reductions in triglycerides, LDL cholesterol, liver fat content and blood pressure. The U.S. FDA has granted Fast Track designation to pemvidutide for the treatment of MASH. Pemvidutide recently completed the MOMENTUM Phase 2 obesity trial and is being studied in the ongoing IMPACT Phase 2b MASH trial.
