GAITHERSBURG, Md., Aug. 10, 2023 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the three months ended June 30, 2023, and provided a business update.

“We are pleased to have commenced enrollment in our IMPACT Phase 2b biopsy-driven trial of pemvidutide in NASH,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “We believe our compelling Phase 1b data in subjects with nonalcoholic fatty liver disease (NAFLD) demonstrating class-leading improvements in liver fat and markers of liver inflammation support the prospects of achieving robust rates of NASH resolution and fibrosis improvement in our IMPACT trial. We are also eager to report our 48-week data from the MOMENTUM Phase 2 obesity trial next quarter. We believe the pemvidutide data showing significant weight loss, combined with robust reductions in liver fat content, serum lipids and blood pressure without cardiovascular safety signals could offer a differentiated product profile that meaningfully impacts patients with obesity and NAFLD or dyslipidemia, and patients with NASH.”

Recent Highlights and Anticipated Milestones

Pemvidutide

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

  • 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.

  • Approximately 320 subjects with obesity or overweight but 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.

  • 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.

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

• Commenced enrollment in IMPACT Phase 2b NASH trial
  
  

  • 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.

  • 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.

  • 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.

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

HepTcell™

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

  • The multicenter 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).

  • Subjects were randomized 1:1 to HepTcell or placebo.

  • 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.

  • 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 June 30, 2023

• Cash, cash equivalents and short-term investments totaled $160.0 million as of June 30, 2023.

• Research and development expenses were $13.3 million for the three months ended June 30, 2023, compared to $16.0 million in the same period in 2022. The expenses for the quarter ended June 30, 2023 included $5.6 million in direct costs related to development activities for pemvidutide and $1.8 million in direct costs related to development activities for HepTcell.

• General and administrative expenses were $4.8 million for the three months ended June 30, 2023, compared to $4.4 million in the same period in 2022. The change was primarily attributable to increased stock compensation and other labor related expenses.

• Interest income for the three months ended June 30, 2023 was $1.8 million as compared to $0.3 million in the same period in 2022.

• Net loss for the three months ended June 30, 2023 was $16.1 million, or $0.32 net loss per share, compared to a net loss of $20.1 million, or $0.42 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™ 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 obesity and liver diseases. 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™, an immunotherapeutic designed to achieve a functional cure for CHB. For more information, please visit www.altimmune.com.
