Thank you, Jerry. I am very excited to share that we continue to advance our clinical programs across MASH, AUD, and ALD. Beginning with our program in MASH. Last week, we announced the initiation of the global PERFORMA Phase III trial of pemvidutide in MASH and began enrolling patients. Over the last few months, we moved very rapidly to set up a strong and experienced global infrastructure to initiate the trial. The trial will be conducted across approximately 300 sites with 1/3 in the U.S. and 2/3 ex-U.S. We are working closely with our CRO on site activation in multiple countries and ensuring a smooth start to the trial for an efficient enrollment. The initiation of PERFORMA is an important milestone for Altimmune and for the advancement of MASH treatment. We also see a growing interest and excitement for pemvidutide in MASH from the scientific community. Our increased presence and engagement with the scientific community at the EASL and SOAR medical conferences this year is driving awareness and has helped build momentum as we begin enrolling patients. Based on the strong Phase II data we reported last year and the design of the PERFORMA trial, we are looking forward to studying pemvidutide in a registrational setting. Moving to AUD. In July, we were very happy to report the strongly positive top-line data from the RECLAIM Phase II trial in AUD. The data readout was based on an ITT analysis as it would be for a pivotal study. The trial met its primary endpoints where pemvidutide 2.4 mg showed a highly statistically significant reduction in the average number of heavy drinking days versus placebo at week 24 with a treatment difference of 1.45 heavy drinking days per week. Pemvidutide also met two critical secondary endpoints, both of which are registrational endpoints recognized by the FDA. On the first endpoint, we saw a highly statistically significant response in the 2-level reduction in WHO RDL versus placebo. Roughly 2/3 of pemvi patients achieved a 2-level reduction in WHO RDL. This is only 1/3 on placebo. On the other FDA registrational endpoint of 0 heavy drinking days, one that has historically been challenging to achieve, pemvidutide again showed a highly statistically significant improvement in percentage of patients with 0 heavy drinking days. In these data, more than twice the number of the pemvi patients achieved 0 heavy drinking days versus placebo patients. The trial also saw a highly statistically significant change in the percentage of days with drinking abstinence and PEth levels, which is an objective blood-based measure of recent alcohol intake over the last 2 to 4 weeks. Pemvi also showed a meaningful and statistically significant reduction in body weight from baseline with a 9.1% reduction with pemvidutide versus placebo. The totality of the data, including patients' reported measures, such as the decrease in heavy drinking days, WHO RDL reduction, and the increase in 0 heavy drinking days, as well as the PEth objective measure of alcohol intake, shows strong and consistent evidence in pemvidutide's potential to address the excessive alcohol usage in AUD patients. Considering the landscape of clinical studies in AUD, including looking at other available GLP-1 AUD trials, the totality of the RECLAIM data is to our knowledge the most robust to date. While RECLAIM was focused on drinking behavior, we evaluated in an exploratory manner whether patients with elevated FIB-4 above the threshold of 1.3 at baseline were seeing any improvement. FIB-4 is an established biomarker correlated with risk for developing liver fibrosis. Given pemvi's direct glucagon effect on the liver, the observed data with 50% of pemvidutide patients with a FIB-4 index above 1.3 at baseline, achieving less than 1.3 after only 24 weeks, versus only 17% in placebo, is very encouraging, especially at such an early time point. We expect to further evaluate the potential liver benefit in the Phase III study in AUD. In terms of safety and tolerability, pemvidutide continue to demonstrate a generally consistent safety and tolerability profile. Let me share a few thoughts as we look ahead to a potential Phase III study in AUD, which of course will be subject to our dialogue with U.S. and European regulators. We would plan a Phase III study in the moderate to severe AUD population. It is important to note that approximately 50% of AUD patients also have ALD. Therefore, we would expect to study a portion of ALD patients in the AUD Phase III trial. We would look to broaden the study population to also include patients with a BMI under 25 and could explore a lower dosage option. We look forward to engaging with the FDA at the end of Phase II meeting and discussing a path forward for AUD. In addition, we also plan to engage with European agencies such as EMA. In ALD, we are pleased to report that we completed patient enrollment in the RESTORE trial and expect top-line data in the second half of 2027. The trial enrolled approximately 120 patients with ALD and a history of chronic and heavy drinking at baseline. To support future regulatory discussion, we have amended the trial protocol to be able to fully demonstrate the liver benefits in the ALD population that pemvidutide may provide at 1 year. The primary endpoint of the trial, the change from baseline in liver stiffness measurements, or LSM, will now be assessed in a hierarchical manner at week 48 and then at week 24, allowing for both time points to be assessed. The RESTORE trial is now designed to show a liver benefit over a long period of time, and this is consistent with our development strategy of focusing on higher-risk patients. Demonstrating a liver benefit over a long period of time could be a key differentiator for pemvi versus other AUD therapies in development because AUD patients are often already presenting some level of liver impairment. In summary, we are very encouraged by the progress we are making as we move closer to delivering on our mission of helping the millions of patients with serious liver disease. And with that, I will turn the call to Linda.
