Altimmune Announces First Quarter 2022 Financial Results and Provides a Corporate Update

Multiple clinical trial data readouts expected in Q3 and Q4 2022

GAITHERSBURG, Md., May 12, 2022 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the three months ended March 31, 2022 and provided a corporate update.

“We continue to advance the development of pemvidutide, our GLP-1/Glucagon dual receptor agonist and look forward to reporting both weight loss and liver fat reduction data from multiple ongoing clinical trials later this year,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “Based on a greater than 10% weight loss after only 12 weeks of treatment, we believe that pemvidutide has the potential to deliver weight loss comparable to the results of bariatric surgery in people with obesity. In addition, we believe that pemvidutide will have a highly differentiated product profile compared to other products in development—no dose titration, faster weight loss, and robust reductions in lipids. If achieved, we believe these features would translate into greater ease of administration, improved adherence to therapy, and greater potential for cardiovascular benefit.”

Recent Highlights and Anticipated Milestones:

Pemvidutide¹ (ALT-801)

• Enrollment ongoing in 48-week Phase 2 MOMENTUM trial of pemvidutide in obesity
  
  
  • This Phase 2 trial is being conducted at approximately 25 sites in the U.S., with Dr. Lou Aronne, Professor of Clinical Medicine, Weill Cornell Medical College, a leading authority in obesity and obesity clinical trials, serving as the Principal Investigator.
    
  • The trial is expected to enroll approximately 320 non-diabetic subjects with either obesity or overweight. Subjects are being randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 48 weeks.
  • The primary endpoint is the relative (percent) change in body weight at 48 weeks compared to baseline, with additional readouts including metabolic and lipid profiles, cardiovascular measures and glucose homeostasis.
  • Dosing has commenced and an interim analysis is planned to assess changes in body weight after 24 weeks of treatment, with an expected readout in Q4 2022.

• Enrollment completed in 12-week Phase 1b nonalcoholic fatty liver disease (NAFLD) trial
  
  
  • This Phase 1b trial is being conducted in the U.S., with Dr. Stephen A. Harrison, Director, Pinnacle Research and University of Oxford, serving as Principal Investigator.
    
  • The trial is comprised of non-diabetic and diabetic subjects randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 12 weeks.
  • The primary efficacy readouts are liver fat reduction and weight loss at day 85 (12 weeks).
  • Data readout expected in Q3 2022.

• Enrollment ongoing in Phase 1b NAFLD extension trial
  • This 12-week extension trial allows subjects who have completed the 12-week Phase 1b NAFLD trial to receive a total of 24 weeks of treatment, with an expected data readout on weight loss at 24 weeks in Q4 2022.

• Enrollment ongoing in Phase 1b trial of diabetic subjects with obesity and overweight
  • This 12-week trial will expand on findings from our first-in-human trial in subjects with obesity and overweight, in whom decreased insulin resistance and maintenance of glucose control were observed, including subjects with pre-diabetes.

Financial Results for the Three Months Ended March 31, 2022

• Altimmune had cash, cash equivalents and restricted cash totaling $180.0 million at March 31, 2022.
• Revenue was minimal for the three months ended March 31, 2022 compared to $0.8 million in the same period in 2021. The change in revenue quarter over quarter was primarily due to the discontinuation of development activities for the T-COVID and NasoShield programs.
• Research and development expenses were $15.1 million for the three months ended March 31, 2022, compared to $11.9 million in the same period in 2021. The expenses for the quarter ended March 31, 2022 included $10.8 million in direct costs related to development activities for pemvidutide and $2.5 million in direct costs related to development activities for HepTcell.
• General and administrative expenses were $4.4 million for the three months ended March 31, 2022, compared to $3.8 million in the same period in 2021. The change was primarily attributable to increased stock compensation expense.
• Net loss for the three months ended March 31, 2022 was $19.4 million, or $0.44 net loss per share, compared to $14.9 million in the same period in 2021, or $0.38 net loss per share.
• 2022 operating expense guidance will be provided on the conference call.

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. By combining GLP-1 and glucagon activity in a single peptide, pemvidutide has the potential to achieve weight loss comparable to the results of bariatric surgery. Pemvidutide incorporates the EuPort^TM domain, a proprietary technology that increases its serum half-life for weekly dosing while slowing the entry of pemvidutide into the bloodstream, which may improve its tolerability. In a 12-week Phase 1 clinical trial, pemvidutide-treated subjects demonstrated striking reductions in body weight, liver fat and serum lipids commonly associated with cardiovascular disease.

About HepTcell

HepTcell is a novel, investigational, immunotherapeutic comprised of nine synthetic peptides representing conserved hepatitis B (HBV) sequences 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.
