"We continue on course in our advancement of pemvidutide for two important clinical indications, obesity and non-alcoholic steatohepatitis (NASH), and look forward to data readouts from our NAFLD trial extension in mid-December 2022 and from our interim 24-week readout on approximately 160 subjects from our MOMENTUM Phase 2 obesity trial in Q1 2023," said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune.

"We believe that the promising reductions in liver fat content and alanine aminotransferase (ALT) levels observed in our recently completed 12-week Phase 1b NAFLD trial should translate into success on the approvable NASH endpoints, including NASH resolution and fibrosis improvement, in late-phase biopsy trials. The magnitude of the effects on the liver combined with meaningful reductions in body weight could represent important points of differentiation from other drugs in development for NASH."

Dr. Garg added, "Turning to our MOMENTUM obesity trial, we believe that the level of weight loss we expect to see at 48 weeks will be similar to the leading drugs in the class. The trial is being conducted in a typical obesity population at established obesity trial sites and employs lifestyle interventions that are standard in obesity trials. We believe the absence of dose titration, together with the favorable tolerability profile, reductions in serum lipids and reductions in liver fat content observed in clinical trials to date, could translate into greater ease of administration, improved adherence to therapy and greater potential for cardiovascular benefit in this patient population."

Recent Highlights and Anticipated Milestones:

Pemvidutide

Topline data readout from 12-week Phase 1b NAFLD trial in September 2022
This trial was conducted in the U.S., with Dr. Stephen A. Harrison, Director, Pinnacle Research and University of Oxford, serving as Principal Investigator.
A total of 94 subjects were randomized and dosed, with approximately 80% being of Hispanic ethnicity, and with a median liver fat content of approximately 22%.
A 68.5% relative reduction in liver fat content was achieved at the 1.8 mg dose at Week 12, with 94.4% of subjects achieving a 30% reduction of liver fat and 55.6% achieving normalization of liver fat, defined as 5% or less on MRI-PDFF, at Week 12.
As announced in a late-breaking abstract presented on November 7, 2022, at the annual meeting of the American Association for the Study of Liver Diseases (AASLD) in Washington, DC, greater than 83% of subjects who received pemvidutide and who participated in a corrected T1 (cT1) imaging sub-study achieved an 80 millisecond (ms) or more reduction in cT1 relaxation times at Week 12 at each pemvidutide dose. Elevated cT1 scores have been correlated with hepatic and cardiovascular events in clinical studies. An 80 ms reduction has been shown to correlate with a 2-point improvement in NAFLD Activity Score on liver biopsies.

Topline 24-week data from NAFLD trial (12-week extension) expected mid-December 2022
This extension trial provides 12 weeks of additional treatment to subjects with NAFLD who completed the 12-week Phase 1b trial, allowing subjects to receive a total of 24 weeks of treatment.
Although the extension trial was initiated several months after the start of the original 12-week Phase 1b NAFLD trial, a total of 66 of 94 subjects (70%) rolled over into this trial.
Randomization and first dosing of all subjects is complete in 48-week Phase 2 MOMENTUM obesity trial – 24-week interim analysis of approximately 160 subjects expected in Q1 2023
This Phase 2 trial is being conducted at 30 sites across 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 was designed to enroll approximately 320 non-diabetic subjects with obesity, or overweight with at least one co-morbidity. 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. Baseline characteristics of the study population include median body weight and body mass index (BMI) of approximately 101 kg and 36 kg/m2, respectively, and median liver fat content of approximately 5%, as measured in approximately 100 subjects participating in a body composition sub-study. The study population is approximately 75% female, and approximately 20% of subjects are of Hispanic ethnicity.
The primary endpoint is the relative (percent) change in body weight at 48 weeks compared to baseline. Additional readouts include metabolic and lipid profiles, cardiovascular measures and glucose homeostasis.
A 24-week interim analysis on approximately 160 subjects is planned in Q1 2023.
Enrollment complete in Phase 1b trial of subjects with type 2 diabetes
This 12-week safety trial will evaluate the effects of pemvidutide in approximately 48 subjects with type 2 diabetes and obesity or overweight.
Data readout is expected in Q1 2023.
HepTcell

Enrollment continuing in the Phase 2 clinical trial in chronic hepatitis B
Endpoints include virological markers of hepatitis B infection and functional cure.
Data readout is expected in H2 2023.
Financial Results for the Three Months Ended September 30, 2022

Altimmune had cash, cash equivalents and short-term investments totaling $201.9 million at September 30, 2022.
Revenue was minimal for the three months ended September 30, 2022 compared to $0.2 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 in 2021.
Research and development expenses were $20.3 million for the three months ended September 30, 2022, compared to $29.2 million in the same period in 2021. The expenses for the quarter ended September 30, 2022 included $14.0 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 $4.5 million for the three months ended September 30, 2022, compared to $4.2 million in the same period in 2021. The change was primarily attributable to increased stock compensation expense.
Net loss for the three months ended September 30, 2022 was $23.5 million, or $0.48 net loss per share, compared to a net loss of $33.5 million, or $0.81 net loss per share, in the same period in 2021.

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. Pemvidutide incorporates the EuPortTM 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 1b clinical trial, NAFLD subjects treated with pemvidutide demonstrated promising reductions in liver fat content, serum ALT levels and body weight.

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.
