Thank you, Jim. First, I will discuss our Australian oncology study. As most of you have hopefully seen, earlier this week, we announced that the first patient was enrolled at the Royal Adelaide Hospital in Adelaide, Australia. And we are excited to update that now with the enrollment of a second patient from the same hospital. This marks a critical milestone for our oncology program and also constitutes great progress in the 6 months since we announced that we had preclinical data to support going forward with the clinical trial. Additionally, Pindara Private Hospital, in Gold Coast, Australia is now open for patient enrollment and is actively screening for eligible subjects. Going forward, we expect to continue to enroll patients in this safety, feasibility and dose-finding trial of the Hemopurifier in patients with solid tumors who failed treatment with anti-PD-1 antibodies. Two observations would support this. One is we're seeing active prescreening logs from our sites, and we are heartened by the fact that patients, as indicated by the 2 we've enrolled, have thought the study interesting enough and important enough to go ahead and signed informed consent to be in the trial. We are awaiting full ethics board approval from a third Australian hospital located in Sydney. The Aethlon team recently visited Australia between the 9th of October and the 16th of October of this year. On October 10, we had a site visit with the lab of Professor George Grau at the University of Sydney, who will be performing the central lab extracellular vesicle and T cell studies on samples from patients enrolled in the study. On October 11, we had a highly interactive investigator meeting with members of all 3 Australian sites clinical research teams. This was then followed by individual site visits to all 3 clinical sites for training on the use of the Aethlon Hemopurifier. Also in the second quarter, we received ethics committee approval from Medanta Medicity Hospital in India for a similar 9to 18 patient safety, feasibility and dose-finding trial of the Hemopurifier. We have secured a clinical trial agreement with this site as well, and enrollment can proceed once we have regulatory approval for importing of the devices by the Central Drugs Standard Control Organization, known as the CDSCO. As a reminder, the primary endpoint of the approximate 9 to 18 patient safety, feasibility and dose-finding trial is safety. The trials will monitor adverse events and clinically significant changes in lab tests of Hemopurifier treated patients with solid tumors with stable or progressive disease at different treatment intervals after a 2-month run-in period of the anti-PD-1 therapy, either KEYTRUDA or Opdivo monotherapy. Patients who don't respond to the anti-PD-1 antibody therapy will be eligible to enter the Hemopurifier phase of the study, where sequential cohorts will receive either 1, 2 or 3 Hemopurifier treatments during a 1-week period. In addition to monitoring for safety, the study is designed to examine the number of Hemopurifier treatments needed to decrease the concentration of extracellular vesicles and if those changes in EV concentrations improve the body's own natural ability to attack tumor cells. These exploratory central laboratory analyses are expected to inform the design of a subsequent efficacy and safety trial, including a premarket approval known as a PMA study required by the FDA and other regulatory agencies. Please note that currently, only approximately 30% to 40% of patients who receive the anti-PD-1 therapies, pembrolizumab or nivolumab will have a lasting clinical response to these agents. EVs produced by tumors have been implicated in the spread of cancers and the resistance of those agents to those agents, the anti-PD-1 therapies. The Aethlon Hemopurifier has been designed to bind and remove these EVs from the bloodstream, which may improve these therapeutic response rates to anti-PD-1 antibodies. In the preclinical studies I mentioned, the Hemopurifier has been shown to reduce the number of EVs in cancer patient plasma samples. The company also continues to explore opportunities to expand the use of the Hemopurifier as a treatment for life-threatening viral infections. In vitro, it has shown effectiveness in binding a large library of envelope viruses, including those of recent concern, both domestically and internationally, including Marburg virus, Lassa virus, dengue, SARS-CoV-2 and H5N1 bird flu. That said, we believe that we stand poised to respond in the event of an epidemic or outbreak involving an envelope virus. With that, I'll turn the call back over to Jim for the financial discussion, and he will then open it up for questions.
