Thank you, Jim, and thanks to everybody on the line for dialing in. As you can see from our recent announcements and more to come today, we’ve had a busy and productive few months since our last call. On the oncology front, we now have IRB approval to initiate our early feasibility study, which to remind you as a device equivalent of a Phase 1 study for a drug in head and neck cancer at the Hillman Cancer Center at the University of Pittsburgh, under the direction of Dr. Dan Zandberg, who is a very bright young medical oncologist, who specializes in head and neck cancer. And also, collaborating with basic researchers there who are world experts in the role of exosomes in cancer progression and metastasis. We expect that the trial will be open for patient enrollment within the next few weeks, and it will be listed on clinicaltrials.gov in the next day or two. Once that listing goes up on clinicaltrials.gov, we’ll put a link to it on our website and you’ll be able to see more details of the trial. But in brief, the trial, which will enroll 10 to 12 subjects in an open-label design, will combine Hemopurifier treatment with pembrolizumab or trade name of Keytruda from Merck in patients with advanced and/or metastatic disease in the frontline setting. Pembrolizumab was approved in the frontline setting last June based on studies showing that it improved survival by several months on average. But like other checkpoint inhibitors or immuno-oncology agents in other solid tumors, such as melanoma and non-small cell lung cancer, its impact is substantial, but on a minority of patients. Some patients may have striking outcomes with multi-year survival in advanced disease, which prior to the advent of these agents was unheard of. But the majority of patients unfortunately show little or no improvement. Studies have shown that a major mechanism of resistance to these agents may involve tumor-derived immunosuppressive exosomes, which as we have previously described, are subcellular particles that are shed from tumor cells and circulate in these patients. We’ve previously shown the laboratory version of the Hemopurifier can clear exosomes from multiple tumor types, as described in a poster that we presented at the online AACR, American Association for Cancer Research Meeting this week. You can find a link to this poster on our website. In the trial, we will treat enrolled patients with a four-hour Hemopurifier treatment immediately prior to their first two every three-week pembrolizumab administrations. The primary endpoint for this trial, as always, in these types of early trials is safety with secondary endpoints, including tumor response, survival, and most importantly, from a mechanism of action perspective, we will be able to investigate the clearance and characterization of exosomes and potentially to understand that clearance and its relationship to improved outcomes. Now to move on to infectious disease. We announced last week that the FDA has approved a supplement to our existing viral IDE, or Investigational Device Exemption, to allow for the treatment with the Hemopurifier of up to 40 patients with SARS-CoV-2/COVID-19 disease, add up to 20 centers in the United States. The supplement is very similar to the one that was approved several years ago for Ebola in both the United States and in Canada, and that supplement remains open. We previously discussed and put up a statement on our website of the potential use of the Hemopurifier in COVID-19. And we noted that we have data with multiple viruses in vitro and in humans, including a version of the MERS virus, which like SARS-CoV-2 is a beta coronavirus so closely related showing that the Hemopurifier or a lab version of it could clear substantial quantities of virus in circulation. While at the time we posted that statement, we did not have data with SARS-CoV-2. We now have shown that we can clear a specific SARS-CoV-2 protein in the lab. We have not demonstrated clearance of whole virus because of safety issues that it would have to be done in a much higher level seclusion facility. But given the data with all of the other viruses that we’ve shown and our ability to very effectively clear this protein, we have a high degree of confidence that the Hemopurifier will trap the SARS-CoV-2/COVID-19 virus. We also discussed at that time, the question of whether clearing circulating virus would have an impact on a disease, where the proximate target is the lung. The literature has evolved very rapidly, as many of you probably know, since the original description of the outbreak in China. And the literature regarding the disease is now very clear that although the lung is frequently one of the first organs involved in many patients and particularly in the most severe – severely affected ones, this is a systemic disease that potentially affects all organ systems and that the sickest patients out – sickest patients outcomes may be driven by other organ involvement, including cardiac disease and the profound coagulopathies or abnormalities of blood coagulation that characterize their courses. In fact, there’s some evidence that the lung disease may, in fact, be initiated in many patients, not from the top from the alveoli, but in fact, through the microcirculation in the lung. We’re now in the process of identifying centers to initiate the investigation of the Hemopurifier in this disease. Finally, before I ask for Chuck’s thoughts and turn it back over to Jim, I want to comment on a new addition to the management team. We recently recruited Tom Taccini to the position of Vice President of Manufacturing and Product Development. Tom is an industry veteran, with more than 35 years of experience in mechanic - medical devices and expertise in manufacturing, product development, quality systems, regulatory affairs, and program and project management. He is already in place and is having a major impact on helping to advance our manufacturing capabilities. What many observers of our industry generally don’t recognize is the critical role that manufacturing and product development play in the process of getting to market. Clinical development gets most of the attention, but no product gets approved without reproducible, scalable, reliable and well-characterized manufacturing processes. And we’re devoting very substantial resources to make sure that this is not rate-limiting in the development of the Hemopurifier. This is doubly important in products for life threatening diseases, where development can move very quickly. To remind you, the Hemopurifier is a subject of two breakthrough device designations by FDA, one for viral disease and one for oncology. And in this setting, the regulatory process and the development process can move very quickly. So we have to be prepared by the time we’re ready to file for approval assuming our development programs are successful. Tom is a great addition to the team. But I would also be remiss if I didn’t point out that all of what I’ve been talking about was done in a very short time with a small, but incredibly talented and motivated team of scientists and development professionals to whom we are profoundly indebted. And while our group is taking all appropriate precautions to protect each other during these challenging times, including working remotely wherever possible, we have continued research in our laboratories. We continue our manufacturing operations to manufacture Hemopurifiers for our clinical trials. With that, I’d like to get Chuck’s thoughts and observations before turning it back over to Jim for the financial section of the call. Chuck? Make sure you’re not unmute, Chuck.
