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

Initiation of the IMPACT Phase 2b trial of pemvidutide in non-alcoholic steatohepatitis (NASH) expected mid-2023

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

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

Webcast to be held today, May 11, 2023, at 8:30 am EDT

GAITHERSBURG, Maryland -- May 11, 2023 -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced financial results for the three months ended March 31, 2023, and provided a business update.

“We are on course for mid-year initiation of IMPACT, our Phase 2b biopsy trial of pemvidutide in subjects with NASH,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “In our previous trials in subjects with non-alcoholic fatty liver disease (NAFLD), we observed remarkable reductions in liver fat content and markers of liver inflammation that occurred rapidly after treatment. This leads us to believe that the IMPACT trial has the potential to show a statistically significant impact on the key endpoints of NASH resolution and fibrosis improvement. We also believe pemvidutide may distinguish itself from other candidates in development for NASH because of its demonstrated reductions in both liver fat content and body weight. This is important, because many NASH patients suffer not only from the complications of liver disease but also from the underlying obesity, a principal driver of NASH. In addition, we eagerly await top-line 48-week results from our MOMENTUM obesity trial anticipated in the fourth quarter of 2023, which we expect will demonstrate continued weight loss beyond the robust levels reported at the 24-week interim analysis. We believe pemvidutide could be an important treatment option for patients with obesity, if approved, particularly those with NAFLD and dyslipidemia, conditions that are highly prevalent in these patients. We also look forward to the top-line results of our Phase 2 trial of HepTcell in CHB, which we expect to announce in the first quarter of 2024.”

Recent Highlights and Anticipated Milestones

Pemvidutide

● Positive interim data readout from 24-week MOMENTUM Phase 2 obesity trial in March 2023

o Mean weight loss of 10.7% and 9.4% at the 2.4 mg and 1.8 mg doses, respectively, at Week 24, compared to mean weight loss of 1.0% in the placebo group.

o Approximately 50% of subjects achieved 10% or more weight loss and approximately 20% of subjects achieved 15% or more weight loss at both the 2.4 mg and 1.8 mg doses at Week 24.

o Robust reductions in waist circumference, serum lipids and blood pressure, surrogates of reduced cardiovascular risk.

o Higher adverse event discontinuation rates observed at the 2.4 mg dose can be mitigated by allowance for dose reduction in Phase 3 trials.

● Initiation of IMPACT Phase 2b NASH trial expected mid-2023

o This Phase 2b biopsy-driven NASH trial will be 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 190 subjects with and without diabetes are planned to be randomized 1:2:2 to pemvidutide 1.2 mg, pemvidutide 1.8 mg, 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 to a total of 48 weeks for assessment of safety and additional biomarker responses.

o Dose reduction will be allowed for subjects who experience GI intolerance.

o The trial is expected to commence mid-2023 with top-line results expected in the first quarter of 2025.

HepTcell^TM

● Completed enrollment in the Phase 2 clinical trial in CHB

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.

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 March 31, 2023

● Cash, cash equivalents and short-term investments totaled $165.8 million as of March 31, 2023.

● Research and development expenses were $17.2 million for the three months ended March 31, 2023, compared to $15.1 million in the same period in 2022. The expenses for the quarter ended March 31, 2023 included $8.7 million in direct costs related to development activities for pemvidutide and $2.1 million in direct costs related to development activities for HepTcell.

● General and administrative expenses were consistent period-over-period at $4.5 million and $4.4 million for the three months ended March 31, 2023 and March 31, 2022, respectively.

● Interest income for the three months ended March 31, 2023 was $1.7 million as compared to a negligible amount in the three months ended March 31, 2022.

● Net loss for the three months ended March 31, 2023 was $20.1 million, or $0.40 net loss per share, compared to a net loss of $19.4 million, or $0.44 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 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.

About Altimmune

Altimmune is a clinical-stage biopharmaceutical company focused on the development of novel peptide-based 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^TM, an immunotherapeutic designed to achieve a functional cure for CHB. For more information, please visitwww.altimmune.com.
