Thank you, Jim. Ongoing progress has been made in our Australian oncology trial of the Hemopurifier in participants with solid tumors not responding to a treatment regimen that includes immunotherapy with the anti-PD-1 agent, pembrolizumab, known as Keytruda, or nivolumab, known as Opdivo. We have previously reported the successful completion of the first cohort where 3 participants received a single Hemopurifier treatment without any device-related serious adverse events or dose-limiting toxicities. Favorable directional improvement in EV numbers and immune cell numbers were observed in this cohort with the HP treatment. We have now completed 2 HP treatments in 2 participants in the second cohort of the trial. We have also recently enrolled a third patient who has passed screening and is due to receive the 2 Hemopurifier treatments by the end of March -- excuse me, by the end of February. Once the 3 patients have completed treatment in Cohort 2, safety data will be presented to an independent Data Safety Monitoring Board. We are targeting late March for this meeting. The DSMB will provide Aethlon Medical with a recommendation to either advance to the third and final cohort of the trial where patients will get 3 Hemopurifier treatments in a given week or they may require 3 additional patients in the current cohort. Aethlon has noted an uptick in the number of interested potential participants in the study since we contracted the groups Trialfacts and Dedicated. Trialfacts performs online advertising of the trial, while Dedicated performs phone prescreening of interested participants. Participants who pass this initial screening are then referred on to the 3 investigative sites for informed consent and more detailed screening. This process has already resulted in HP treatment treated patients in the study and has provided a pool of potential future participants for Cohort 3 of the study. As a reminder, this 9 to 18-patient safety feasibility and dose-finding trial is in patients with solid tumors with stable or progressive disease while on a treatment regimen that includes either Keytruda or Opdivo. Patients who meet all exclusion -- all inclusion and no exclusion criteria are enrolled in sequential cohorts to receive 1, 2 or 3 Hemopurifier treatments during a treatment week. In addition to monitoring safety, the study is designed to examine the number of Hemopurifier treatments needed to decrease the concentration of extracellular vesicles and if these changes in EV concentrations improves the body's own natural ability to attack tumor cells. The scientific rationale and full design of this study have recently been published in the peer-reviewed journal, BMJ Open, and the link to this article could be found on the Aethlon Medical website. I'll now change gears and talk about the R&D update. Under a Material Transfer Agreement, Stavro is studying the compatibility of the Hemopurifier with their SLAMB system. This system utilizes a single small lumen vascular catheter and a simplified blood pump, compared to the large double-lumen vascular catheter and more complicated dialysis machines typically used for the treatment. This research could lead to a simplified system for performing Hemopurifier treatments in oncology units and in infusion centers in the future without the requirement to use a large double-lumen dialysis catheter, a bed in a dialysis unit, a dialysis machine or a supervising nephrologist. The Aethlon Medical R&D team continues to attempt to build on our preclinical data in Long COVID. We have previously shown that the GNA affinity resin in the Hemopurifier binds EVs in Long COVID patient samples and decreases microRNAs known to cause immune dysregulation. This data has been published in the preprint server bioRxiv and has been submitted for consideration in a peer-reviewed journal. We are now exploring possibilities of investigating other cargo within the EVs, such as viral particles, with our technology. Extracellular vesicles, including platelet-derived EVs, have been implicated in the pathogenesis of a myriad of indications in addition to cancer, including, but not limited to, lupus, rheumatoid arthritis, systemic sclerosis, multiple sclerosis, cardiovascular diseases, sepsis and ALS. Aethlon previously published data on the removal of platelet-derived EVs from healthy plasma by the Hemopurifier in the preprint server bioRxiv. We plan to further this work by examining platelet-derived EV and microRNA removal by Hemopurifier -- by the Hemopurifier in patients with some of these indications, so disease plasma, to further this work. This approach is in line with our thinking that the Aethlon Hemopurifier may provide a pipeline within a single device. With that, I'll turn the call back over to Jim for the financial discussion.
