Thank you, Jim. Steady progress has been made in our Australian Oncology trial of the Hemopurifier in patients with solid tumors. To date, three patients have been enrolled. Two patients did not advance to the Hemopurifier treatment phase of the study due to pre specified stopping criteria during the two-month running period. One had showed a clinical response to anti-PD-1 therapy alone, while the other experienced toxicity to the anti-PD-1 agent. A third patient, who did not respond to the anti-PD-1 therapy, completed a four-hour Hemopurifier treatment at Royal Adelaide Hospital on January 29, 2025. The treatment was completed with no device related issues or immediate complications. At the pre specified Day 7 safety follow-up visit conducted on February 4, 2025, the patient was noted to not have experienced any adverse events and did not have any clinically significant changes in the safety laboratory measurements. Samples were also collected before and after Hemopurifier treatment to be analyzed for extracellular vesicle removal and changes in anti-tumor T cell numbers by the device. This data will be available once all three patients in this patient cohort are treated. Once the seven days safety follow-up period has been completed on the three patients in this first study cohort, an independent data safety monitoring board known as the DSMB will convene regarding advancing to the second cohort where patients will get two Hemopurifier treatments during a given week. Following the investigator meeting with the three clinical sites, Aethlon received valuable feedback from the sites suggesting protocol modifications that could possibly improve enrollment speed, reduce screen failures, shorten the time to Hemopurifier treatments and the time to data. In response, the Athlon team swiftly developed a protocol amendment incorporating these recommendations. Key changes made in the amendment included enrolling patients only after they have been confirmed to not be responding to anti-PD-1 therapy. This adjustment eliminates the need to identify patients within the first two weeks of starting anti-PD-1 therapy, while also removing the two-month run-in period previously required to assess response to therapy. Additionally, restrictions on commonly prescribed concomitant medications that would not impact patient safety were lifted. The amended protocol also broadens eligibility to include patients receiving all approved dosing regimens of pembrolizumab and nivolumab, rather than limiting enrollment to patients on specific schedules of those medications. The company is pleased to announce that the Human Research Ethics Committee, known as HREC and Research Governance Offices known as RGO have all approved this amendment at all three sites. The two currently active sites, Royal Adelaide Hospital and Pindara Private Hospital can enroll under this amended protocol presently. The third site, Genesis Care/Royal North Shore Hospital, can begin enrollment under this amendment following a site initiation visit to be conducted this week, February – on February 14, 2025. The company continues to pursue approval of a similarly designed clinical trial in India. HREC approval has been obtained at Medanta Medicity Hospital, and we are currently awaiting approval from the regulatory agency, CDSCO in India. Recent regulatory changes in India have introduced additional documentation requirements that were previously not necessary. Aethlon is actively responding to CDSCO’s queries through the company’s India CRO, Qualtran. As a reminder, the primary endpoint of the approximate nine to 18-patient, safety, feasibility and dose-finding trial is safety. The trial will monitor any adverse events and clinically significant changes in labs of the Hemopurifier treated patients with solid tumors who have stable or progressive disease at different treatment intervals after a 2-month run-in period of anti-PD-1 therapy, either Keytruda or Opdivo. Patients who don’t respond to the anti-PD-1 therapy will be eligible to enter the Hemopurifier study, where sequential cohorts will receive either one, two or three Hemopurifier treatments during a one-week period. In addition to monitoring safety, the study is designed to examine the number of Hemopurifier treatments needed to decrease the concentration of extracellular verticals, EVs and if these changes in EV concentrations improves 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 study known as the PMA study required by the FDA and other regulatory agencies. Currently, only approximately 30% of patients who received pembrolizumab or nivolumab will have a lasting clinical response to these agents. Extracellular vesicles produced by tumors have been implicated in the spread of the cancers as well as the resistance to anti-PD-1 therapy. The Aethlon Hemopurifier has been designed to bind and remove these EVs from the bloodstream, which may improve therapeutic response rates to anti-PD-1 antibodies. In pre-clinical studies, the Hemopurifier has been shown to reduce the number of EVs in cancer patient plasma samples. The company is closely monitoring developments related to bird flu in the United States, Marburg virus in Rwanda and Ebola virus in Uganda. Aethlon has direct experience with these viruses having previously generated in vitro viral binding data for all three viruses, and treated an Ebola patient in Germany under emergency use conditions. Aethlon will continue to monitor these situations carefully and be poised to respond if currently available treatment strategies are deemed ineffective. Finally, we have previously disclosed that we received samples from patients with Long COVID through the link, known as the long-term impact of infection with novel coronavirus study cohort at the University of California San Francisco Medical Center. EVs, including those containing SARS-CoV-2 have been implicated in the pathogenesis and the resulting symptoms seen in Long COVID. Our research team has been testing these Long COVID samples to see if the proprietary G&A resin in our Hemopurifier binds the EVs in these patient samples. We plan to share this data in the future. With that, I’ll turn the call back over to Jim for the financial discussion, and he will open it up for questions.
