Vipin Garg : Thank you, Rich, and good morning, everyone. We appreciate you joining us today for a discussion of our year-end and fourth quarter 2023 financial results and business update. We are excited about the 2023 achievements with pemvidutide, our GLP-1/glucagon dual receptor agonist, which is in development for the treatment of obesity and MASH, two important clinical indications. Altimmune achieved key milestones in the development of pemvidutide last year, including compelling positive data from our 48-week MOMENTUM Phase II obesity trial and initiation of the impact biopsy-driven Phase IIb trial in MASH. We're also extremely pleased with the results of our body composition analysis from the MOMENTUM Phase II obesity trial of pemvidutide, showing that 74.5% of weight loss came from fat, and only [25.5%] from lean mass.
Our Chief Medical Officer, Scott Harris will review these results in greater detail shortly. The MOMENTUM trial showed that subjects receiving pemvidutide had a mean weight loss of 15.6%, and over 30% of subjects achieved 20% or more weight loss on 2.4 milligram dose of pemvidutide at week 48, along with robust reductions in BMI and serum lipids, as well as improvements in blood pressure without imbalances in cardiac events, arhythmias or clinically meaningful increases in heart rate. In addition, the impressive -- in addition to the impressive body composition data further distinguishes pemvidutide from other compounds in development for the treatment of obesity. Turning to our impact biopsy-driven Phase IIb MASH trial, we are looking forward to announcing the top line 24-week results anticipated in the first quarter of 2025.
We are confident this trial will be successful considering the positive results from our 24-week Phase Ib trial of pemvidutide in subjects with MASLD, where a greater than 75% relative reduction in liver fat content was achieved at the 1.8 milligram and 2.4 milligram dosage at 24 weeks, along with robust reductions in ALT and cT1, both biomarkers of liver inflammation. A recently completed preclinical study demonstrating a direct anti-fibrotic activity of pemvidutide provides evidence of the potential second mechanism for reducing fibrosis in MASH patients. With that, I will now turn call over to our Chief Medical Officer, Dr. Scott Harris to discuss our data and clinical plans. Scott?
Scott Harris : Thank you, Vipin, and good morning, everyone. First, let me tell you about the compelling body composition analysis from the MOMENTUM trial, which showed that 74% of weight loss came from adipose issue, and only 25.5% due to lean mass, comparable to the effects historically associated with diet and exercise programs. These data are among the best results achieved with incretin-based obesity drugs. With an increasing number of anti-obesity candidates in development, there is growing evidence emphasis on the type and quality of weight loss where the ability to preserve lean body mass has been viewed as an important differentiator in the treatment of patients with obesity. Excessive lean mass loss has been associated with negative outcomes such as sarcopenia and bone fractures, especially in women and the elderly.
Additionally, we saw the participants in MOMENTUM preferentially lost visceral fat over subcutaneous fat an important result, as visceral fat like hepatic fat content increases metabolic dysfunction and is highly associated with increased cardiovascular risk. We expect to present a complete analysis of these body composition data at an upcoming scientific meeting. Keep in mind that these favorable body composition data only add to the improvements we observed in serum lipid profile. We're up to 20% -- up to a 20% reduction in total cholesterol, 21% reduction in LDL cholesterol and nearly 56% reduction in triglycerides were observed in MOMENTUM participants with elevated baseline serum lipids. This strengthens our view that pemvidutide has the ability to treat not only obesity, but its key morbidities like cardiovascular disease and MASH.
Recall that in our MOMENTUM Phase II obesity trial, subjects receiving 2.4 milligrams pemvidutide had a mean weight loss of 15.6%, and over 30% of these subjects achieved 20% or more weight loss at week 48. What was equally exciting is that the 2.4 milligram weight loss curve remained linear with no indication of plateauing at week 48. Along with the previously mentioned effects on serum lipids, pemvidutide also demonstrated improvements in blood pressure within imbalances in cardiac events, arrhythmias or clinically meaningful increases in heart rate. Glucose homeostasis was maintained with no significant changes in fasting glucose or hemoglobin A1C. Dr. Louis Aronne, lead investigator for the MOMENTUM trial will present the results of this trial at an upcoming scientific conference.
Now let me talk about the IMPACT biopsy-driven Phase IIb trial. Approximately 190 subjects with or without diabetes are being randomized 1:2:2 to 1.2 milligrams, 1.8 milligrams or 1.8 milligrams pemvidutide placebo administered weekly for 24 weeks. The key endpoints will be MASH resolution or fibrosis improvement after 24 weeks of treatment with subjects followed for an additional 24 weeks for assessment of safety and additional biomarker responses. Enrollment is going well and we expect to have top line results of the IMPACT trial in the first quarter of 2025. We believe that the rapid rate of enrollment reflects the eagerness of MASH patients to achieve significant weight loss in addition to treatment of their liver disease. This past fall, we also reported that FDA granted Fast Track designation for pemvidutide for the treatment of MASH based on the robust and rapid reduction in liver fat content and biomarkers of fiber inflammation observed in our Phase Ib [indiscernible] trial.
We look forward to working closely with the agency in the development of pemvidutide for this important indication. Finally, turning to our Phase II clinical trial of HepTcell and chronic hepatitis B, the overall response in the recently completed trial was insufficient for further development so we are stopping all further development. With that, I will now turn the call over to Dr. Scot Roberts, our Chief Scientific Officer, to discuss some recent preclinical findings. Scot?
Scot Roberts : Thanks, Scott. Good morning, everyone. I'd like to tell you about 2 studies that we've recently completed. The first represents an important development related to the therapeutic mechanism of pemvidutide for NASH. We now have evidence for a direct anti-fibrotic effect of pemvidutide in reducing liver fibrosis. The preclinical model used to chemical treatment to induce fibrosis as opposed to more typical mass models based on obesity and high liver fat content. The chemical model allows for the separation of direct anti-fibrotic effects from the activity following potent de fating of the liver by pemvidutide. The data showed a significant 33% reduction in the amount of fibrosis after only 2 weeks of pemvidutide treatment in the presence of continued chemical exposure.
These data bolster our optimism about obtaining a successful 24-week readout in the IMPACT trial in the first quarter of 2025. In a separate unrelated study, we demonstrated that pemvidutide treatment increased the efficiency of an important process called reverse cholesterol transport or RCT. RCT is the process by which excess cholesterol is removed from tissues and eliminated from the body. It is widely understood that LDL can cause the accumulation of cholesterol in the arteries, leading to atherosclerosis and increased risk for cardiovascular event. In the study, we demonstrated that pemvidutide treatment was able to increase the amount of cholesterol eliminated by the liver by 300% while lowering serum cholesterol levels. Clinically, we have shown that pemvidutide nnot only lowers serum LDL cholesterol by up to 21%, but also shifts the size of LDL particles towards larger particle sizes that cannot enter the vasculatures easily.
The demonstration of increased RCT activity to get reductions in serum lipids and liver fat support a potentially broad role for pemvidutide improving cardiovascular risk in addition to its robust weight loss effects. I will now hand the call over to Rich Eisenstadt to give an update on our third quarter financial results. Rich?
Rich Eisenstadt : Thank you, Scot, and good morning, everyone. It's actually our fourth quarter financial results. For today's call, I will be providing a brief update on Altimmune's full year and fourth quarter 2023 financial and operating results. More comprehensive information will be available in our Form 10-K to be filed with the SEC later today. Altimmune ends the fourth quarter of 2023 with approximately $198 million of cash, cash equivalents and short-term investments, compared to $184.9 million at the end of 2022. We project our existing cash funds us into the first half of 2026, which fully funds our IMPACT trial and MASH, including the anticipated Q1 2025 readout of top line 24-week biopsy data. Turning to the income statement.
Revenue was negligible in the fourth quarter and full years 2023 and 2022. Any revenue reported during such periods was for indirect rate adjustments on a government contract that we are closing out. Research and development expenses were $16.9 million in the fourth quarter of 2023 compared to $19.2 million in the same period of 2022. Approximately $11.4 million of this total for the fourth quarter of 2023 were direct expenses for the conduct of our clinical programs, including $10.3 million in direct costs related to development activities for pemvidutide, and $1.1 million in direct costs related to development activities for HepTcell. R&D expense in the fourth quarter of 2022 included $13.4 million in direct expenses associated with the development of pemvidutide and $1.9 million in direct expenses related to HepTcell development activities.
Research and development expenses were $65.8 million in full year 2023 compared to $70.5 million in the prior year. In full year 2023, we incurred $35.8 million in direct costs associated with the IMPACT and MOMENTUM trials for pemvidutide, and $6.6 million in direct costs associated with the HepTcell campaign. General and administrative expenses were $4.3 million and $3.8 million in each of the fourth quarters of 2023 and 2022. For the full year 2023, general and administrative expenses were $18.1 million versus $17.1 million for full year 2022. The $1 million increase was primarily due to increased stock compensation expense as well as additional labor-related costs in 2023. An impairment loss on intangible assets of $12.4 million was recognized during the fourth quarter of 2023 related to the acquired in-process research and development or IP R&D asset associated with HepTcell.
As previously discussed, the overall response in the Phase II trial is deemed to be insufficient to warrant further advancement in clinical trials, and as a result, we have stopped any further development related to HepTcell. Our quarterly noncash operating expenses for the fourth quarter was -- of 2023 was $15.1 million, including the IP R&D write-off or $2.6 million for just the recurring expenses. For the full year, total noncash operating expenses was $23.8 million or $11.3 million for just the nonrecurring items -- I'm sorry, for the recurring items. I apologize. Net loss for the 3 months ended December 31, 2023, was $31.6 million or $0.54 net loss per share compared to a net loss of $21.7 million or $0.43 net loss per share for the fourth quarter of 2022.
The increase in net loss in the quarter was primarily attributable to the $12.4 million noncash impairment charge, partially offset by $2.3 million lower research and development expenses. Net loss for the year end December 31, 2023, was $88.4 million or $1.66 net loss per share compared to $84.7 million or $1.81 net loss per share for the year ended December 31, 2022. The increase in net loss for the year is primarily attributed to the noncash impairment charge, partially offset by lower research and development expenses in 2023 and a $4.5 million increase in interest income earned on our cash equivalents and short-term investments. I will now turn the call back over to Vipin for his closing remarks. Vipin?
