Thank you, and good afternoon, everyone. Before we start, I would like to state that we will be making certain forward-looking statements during today's presentation. These statements may include statements regarding, among other things, the efficacy, safety and intended utilization of our product candidates, our future research and development plans, including our anticipated conduct and timing of preclinical and clinical studies, our enrollment of patients in our clinical studies, our plans to present or report additional data, our plans regarding regulatory filings, potential regulatory developments involving our product candidates, potential regulatory inspections, revenue and reimbursement estimates, projected terms of definitive agreements, manufacturing capabilities, potential milestone payments and our financial position and possible uses of existing cash and investment resources. Forward-looking statements are based on current information, assumptions and expectations that are subject to change and involve a number of risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements. These and other risks are described in our periodic filings made with the SEC, including our quarterly and annual reports. You are cautioned not to place undue reliance on these forward-looking statements, and we disclaim any obligation to update such statements. With that, I'll turn the call over to Linda Marban, CEO.
Linda Marbán: Thank you, A.J. Good afternoon, everyone, and thank you for joining us on our second quarter conference call. At Capricor, our mission remains unchanged and clear to bring transformative therapies to patients with rare and life-limiting diseases. While this past quarter has presented us with some unique challenges, it has also reinforced our conviction that we have in Deramiocel for the treatment of DMD, the agility of our team and, of course, the promise of our pipeline. In particular, for the Duchenne community, we remain unwavering in our commitment to deliver the first approved therapy aimed at specifically treating the cardiomyopathy that affects nearly every patient with Duchenne muscular dystrophy and remains the leading cause of death in this devastating disease. Now for the latest update on our Biologics License Application or BLA. As previously disclosed, we received a complete response letter from the FDA in July. The CRL stated that the BLA in its current form does not meet the statutory requirements for substantial evidence of effectiveness and also referenced certain CMC items, most of which we had already responded to, which were not reviewed by the FDA due to the issuance of the CRL. As a reminder, approximately 1 year ago in our pre-BLA meeting with the FDA, we requested to switch the primary efficacy endpoint of our ongoing Phase III HOPE-3 study to left ventricular ejection fraction, or LVEF, and the agency responded by encouraging us to submit on currently available data from our HOPE-2 and HOPE-2 open-label extension trials matched to an external natural history comparator and then use the data from our HOPE-3 trial to support potential label expansion in the future. This became the plan that we implemented. While the FDA response contained in the CRL was certainly disappointing, we stand behind the strength of our submission and the substantial progress made throughout the review process. from a successful Pre-License Inspection or PLI, to completion of our mid- cycle review with no deficiencies noted and timely responses to more than 50 information requests from the FDA, we believe we consistently met the agency's expectations throughout the review process. The complete response letter was unexpected given the trajectory of positive interactions. While the FDA continues to evolve under new leadership and its approach to novel therapies to treat rare diseases, we remain focused on working constructively with the FDA to define the clearest and most efficient path forward for Deramiocel and the patients who need it. I would like to emphasize that our HOPE-3 trial is still blinded and will not be unblinded until we have clarity on the path to potential approval from FDA. Let me take a minute to remind you of the features of the HOPE-3 trial. The study is fully enrolled with the last patient last visit occurring in June of this year. HOPE-3 is a double-blind, placebo-controlled clinical trial with a 1:1 randomization, which enrolled 104 patients consisting of 2 arms, Cohort A and Cohort B. The combined power of this trial using both cohorts is greater than 90% with the original primary efficacy endpoint being the performance of the upper limb or the pull version 2.0. Based on a multitude of reasons, not the least of which is the tremendous unmet need of DMD cardiomyopathy. We have submitted a protocol amendment to designate left ventricular ejection fraction or LVEF, as the primary efficacy endpoint and the skeletal muscle endpoint, performance of the upper limb or PUL as a prespecified secondary endpoint. This change is based on multiple factors. One, the objectivity of LVEF as measured by cardiac MRI. Remember, there is no volition in cardiac function as measured by MRI as well as the relevance of left ventricular ejection fraction to the pathophysiology of DMG cardiomyopathy, which has only been recently elucidated by the work of Dr. Jonathan Soslow from Vanderbilt University and the DMD Cardiac Consortium in a study funded by the Office of Orphan Products of the FDA and the NHLBI. In addition, HOPE-3 is well powered to detect the treatment effect on cardiac function. I want to remind you that Capricor developed Deramiocel specifically to address heart disease, particularly the cardiomyopathy associated with DMD. However, until Dr. Soslow's study and its subsequent publication, there were no established efficacy benchmarks in DMD cardiomyopathy for the FDA to use in defining clinical benefit. Our entire regulatory path, including the current BLA, was built on the FDA's guidance on how efficacy should be defined in this patient population. We have always intended for ejection fraction to serve as our primary efficacy endpoint. So while this may appear to be a change in strategy, it is, in fact, a return to the original goals we set early in the development of Deramiocel. To that end, with our Type A meeting with the FDA now scheduled, we have submitted a comprehensive briefing package that addresses the concerns raised in the CRL and outlined several potential paths to approval. These include, first and foremost, the continued review of our previously filed BLA, which we believe meets the applicable regulatory requirements for approval as well as supplementing the current BLA with additional data from HOPE-3, if needed. We believe the current handling of our submission is inconsistent with our interpretation of the FDA written guidances for cell and gene therapies as well as recent public statements addressing the approval of safe and effective therapies for rare disease populations. We are hopeful that FDA will exercise a patient-focused and science-driven approach and rare disease approvals in which they have been emphasizing in the media as well as highlighting in the FDA direct podcasts. Based on the comments of Secretary Kennedy and Commissioner Makary, approving Deramiocel for the treatment of DMD cardiomyopathy seems directly in line with their goals. In conclusion, about a year ago, we received FDA feedback that shaped our decision to submit the BLA based on cardiac endpoints. We provided the requested data and analysis and fully expected any differences in interpretation to be addressed at an advisory committee meeting, one that was ultimately canceled by the FDA without explanation. We are concerned with how our file has been managed because we believe there were opportunities during the review period for the agency to raise the specific issues cited in the CRL before issuing the letter. We have long worked aside the DMD community and understand their calls, both to continue treatment with Deramiocel and to gain access if it becomes commercially available. We will continue to urge the FDA to recognize that cardiomyopathy is a leading cause of death in DMD and a far more severe consequence than the loss of arm function. Deramiocel has demonstrated a strong safety profile and the data indicate it can help stabilize the inevitable decline in cardiac function for people living with DMD. With regard to the CMC and pre-commercial aspects of our program, I am pleased to announce that the FDA has now formally accepted all 483 items from our Pre-License Inspection. This milestone further validates the strength of our quality systems, manufacturing capabilities and overall commercial readiness. In addition, the CMC-related items noted in the CRL have either been addressed prior to the issuance of the CRL or have been internally addressed since. We have prepared formal responses, which we plan to submit with our response to the CRL. Our manufacturing facility in San Diego remains fully operational and in production, and we are being disciplined in our commercial manufacturing investments to ensure we are fully prepared while managing resources wisely. In parallel, we are diligently and strategically investing in launch readiness activities, including physician education, patient services, market access planning and reimbursement. We've also begun working closely with treating physicians across the field of neurology and cardiology who will ultimately collaborate in prescribing Deramiocel to patients with DMD cardiomyopathy, if approved. Many of these clinicians are already familiar with the therapy through their participation in the HOPE-2 and HOPE-3 studies, and we are committed to ensuring a smooth transition to commercial use if approved. At this time, we are focused on seeking approval for Deramiocel in the U.S. And with respect to our global expansion plans, we will provide updates as they become available. Now turning to our exosome program. To remind you, in 2024, we were selected to participate in Project NextGen, an initiative led by the U.S. Department of Health and Human Services aimed at advancing next-generation vaccines for COVID-19 and other potential infectious diseases. Under this program, the National Institutes of Allergy and Infectious Disease, NIAID, will be sponsoring the Phase I clinical trial of our StealthX vaccine. Within the last several weeks, we reached a significant milestone for this program, which was the clearance of the IND and initiation of the trial using StealthX, our exosome platform technology. The Phase I study is being conducted and overseen by NIAID's Division of Microbiology and Infectious Disease, DMID. And I am pleased to report we have already supplied them with our clinical material for use in the trial. The Phase I study is assessing our COVID-19 vaccine product. The trial is divided into 3 arms comprised of 3 escalating doses of the spice spike or S antigen and a combined high-dose S plus the nucleocapsid or N antigen, the multivalent vaccine we have been developing. NIAID is starting with the S first because previous COVID vaccines are mainly S-based, and they wanted to have a basis for comparison with our vaccine candidate using similar antigenic profiles. The end goal is for the adoption of the N+S, which is our multivalent vaccine, and we will provide more updates on this developing program as they become available. We believe that StealthX has the characteristics of a vaccine product that Secretary Kennedy would find acceptable. It contains no adjuvants. It is not mRNA-based, uses a native protein antigen and can be rapidly produced if needed. We have long believed that this type of vaccine checks all the boxes for a safe and effective platform as supported by multiple preclinical studies and upcoming clinical data will allow us to confirm or challenge that hypothesis. This platform also has the potential to address multiple disease areas, including influenza and RSV. While vaccines are not a core focus for us, if our candidate meets U.S. government criteria and demonstrates efficacy, it could potentially open meaningful business development opportunities. Just as importantly, it would serve as strategic proof for our exosome platform, which we hope to advance as a versatile therapeutic engine for rare diseases and beyond. While a majority of our efforts this year have been focused on securing approval for Deramiocel, an additional reason we recruited Dr. Michael Binks as our Chief Medical Officer was his expertise in translational science and medicine. He is now leading efforts to advance our exosome pipeline with the goal of forging strategic partnerships to expand the platform into and beyond vaccines. We believe the differentiated features of exosomes, including low immunogenicity, scalable manufacturing and targeted delivery position Capricor for unique potential opportunities in the therapeutic delivery space. We look forward to sharing updates as they become available. Thank you. And with that, I will now turn the call over to A.J. to run through our financials.
