Thank you, Jim. Good afternoon. Thank you for joining us. Today, I plan to highlight what we’ve accomplished in the first quarter of 2022 in our drug development programs and share what you should be expecting over the next nine months. I will be briefly summarizing Slides 3 to 20. Slides 21 to 40 are pipeline background slides, the content which I have previously presented. As Jim stated, the slides are posted on our website if you want to study them more. Let’s go to our first slide, Slide 3. Processa is a drug development company, focused on improving the quality of life and/or survival of patients who have an unmet medical need condition. These are patients who either have no treatment option or need a better treatment option. Each of our five drugs within our pipeline addresses a different unmet medical need with a potential market size for each drug being $1 billion or more. This means that Processa is giving each of our investors, which includes the Processa staff five independent opportunities or shots on goal to have a blockbuster drug. There’s one thing to state that we have five potential blockbusters. More importantly, we are simultaneously developing all five drugs at various stages, but all are now going through our development process. This process is the regulatory science approach that we started to develop 30 years ago when we worked on two FDA contracts determining the best way to answer and provide the answer to a number of FDA clinical and scientific regulatory questions. Our contracts led to the development of a number of FDA guidances. We now have multiple near-term milestones that we expect to achieve from March to August and at the end of the year. I will discuss these milestones as I briefly review each drug within our pipeline. Next slide. To remind everyone, Slide 4 describes the criteria that we have used to select the five drugs in our pipeline. Since I have already covered some of the slide, I would only like to point out one other key item on the slide. The second criteria in the red box stating efficacy evidence. This means that there is some clinical evidence of efficacy in the targeted population for each of the five drugs or for a drug with very similar pharmacology. Next slide. Now let’s look at a summary of our pipeline. We have four drugs in clinical development. We have next generation capecitabine, which we are rebranding of what we previously called 6422. We have 499, 12852 and 3117. And we have one drug in pre-IND stage. Three of the drugs are for the treatment of cancer. The fourth 499 is for the treatment of ulcerative necrobiosis lipoidica a rare orphan disease. And the fifth 12852 is for the treatment of gastroparesis, an unmet medical need where the present treatment options have serious adverse events associated with them. Next slide. This slide provides you with the highlights of what we have achieved in the first quarter of 2022. We have moved closer to obtaining key data to assist us in our discussions with the FDA, the design of our pivotal trials and our NDA submission. For next generation capecitabine, which we previously defined as 6422 program, we have amended the Phase 1B protocol to better understand the de novo formation of DPD associated with next generation capecitabine and began enrolling patients in the amended protocol. For 499, we’ve expanded our outreach to identify potential ulcerative NL patients in order to complete enrollment for our interim and final analysis in a more timely manner. For 12852, we’ve enrolled five patients for our gastroparesis trial so far. And for 3117, we began developing assays to determine if we could identify potential biomarkers that would predict response to 3117 versus gemcitabine. In addition, we will continue our evaluation of potential development and regulatory paths, which will increase the probability for FDA approval. Next slide. I would like first to give you an update on our next generation capecitabine cancer program. As we have previously stated, the market for next generation capecitabine in colorectal cancer is about $1 billion market. We expect next generation capecitabine to be better than existing capecitabine with less dose limiting side effects and potentially greater efficacy given the higher potency. Next slide. From our Phase 1b trial to-date, we have seen a decrease in the non-cancer killing metabolites that caused dose limiting side effects and we have seen an increase in the potency for 24 to 48 hours. However, these effects did not last for all seven days of chemotherapy treatment. The amended protocol determines, one, the PCS6422 regimens that will inhibit metabolism and increased potency for all seven days of chemotherapy, and two maximum tolerated dose for next generation capecitabine. Next slide. This slide summarize what we’ve accomplished in the first quarter of 2022 and what to expect from Processa over the next nine months, the next generation capecitabine. First, what have we achieve in Q1? One, we’ve amended the Phase 1b protocol, we will be defining the PCS6422 regimens that will inhibit the formation of the non-cancer killing metabolites that cause dose limiting side effects and increase the potency of cancer killing metabolites during all seven days of next generation capecitabine chemotherapy. Two, we’ve already begun enrolling patients in the amended protocol. And three, we hope to add clinical sites to the study to expedite the enrollment. What do we expect to achieve the rest of the year? Well, in mid-2022, we should have identified a dosage regimen for PCS6422 and completed our initial evaluation of using an individualized personalized treatment approach for next generation capecitabine. By the end of the year, we hope to preliminarily identify the maximum tolerated dose of next generation capecitabine and the dosage regimen to be used in our Phase 2b or Phase 3 trial. Next slide. Let me now review PCS499 for the treatment of ulcerative NL. As you may recall, this is a $1 billion rare disease market in which natural healing of the open ulcers during the first one to two years after onset occurs in probably less than 5% of ulcerative NL patients. Next slide. There are no FDA approved treatments and no standard of care, because all off-label treatments have limited efficacy given their dose limiting safety profile. The off-label use drugs include the use of pentoxifylline or as I often call it, PTX. PTX works in closing the ulcers of some patients, but side effects limit the dose that can be administered. PCS499 is the deuterated analog of a metabolite of PTX. PCS499 qualitatively has the same metabolite as PTX, but quantitatively has different amounts of the metabolites resulting in a better safety profile. Next slide. This slide summarizes what we’ve accomplished with PCS499 in the first quarter of 2022 and what to expect over the next nine months. So again, what have we achieved in Q1? Although, COVID has had a major impact on our enrollment, we have expanded our remedial patient identification enrollment efforts in Q1, such that we have one patient in screening now, one patient in pre-screening and five patients have been identified that require a pre-screening evaluation to determine if they meet the basic requirements prior to moving into the screening procedure. Also, we are evaluating additional sites with the hope of bringing on more sites. What do we expect to achieve over the next seven to eight months of 2022? Well, in mid-2022, we expect to have enrolled five to 10 patients in the Phase 2b trial to be used in our interim analysis. At the end of the year, we hope to have the top line data from the interim analysis reading out, and we hope to have completed enrollment for the trial. We do plan to meet with the FDA in 2023 and depending on the results and the FDA meeting initiate our Phase 3 trial at the end of 2023. Next slide. Quickly reviewing PCS12852 for the treatment of gastroparesis. This is a more selective and potent 5-HT4 agonist and other 5-HT4 agonist drugs use off-label to treat gastroparesis. Next slide. Other 5-HT4 agonist, and the only drug approved to treat gastroparesis metoclopramide has serious dose limiting side effects with black box warnings and limited use. Because of the higher potency and greater selectivity for the 5-HT4 receptor, PCS12852 in preclinical and clinical studies requires a much, much lower dose of PCS12852 and has less side effects than these other drugs. Next slide. So, again, what have we achieved and what do we expect to achieve over the next nine months? We’ve enrolled five out of the total 24 patients plan for this trial so far. We expect a complete enrollment of the study in the September, October timeframe with top line readout of the change in gastric empty rate by the end of the year. Next slide. The last drug that I will be reviewing today is the fourth drug for which we have an IND, PCS3117. This is a drug similar to gemcitabine, a cancer drug, which maximum sales of approximately $1 billion and used for a number of cancers as first or second line therapy. But with a treatment failure rate of 55% to 85% across the various cancers is used for. Next slide. PCS3117 presently has an IND for the treatment of pancreatic cancer and preliminary clinical studies have been completed. Some efficacy has already been demonstrated in different populations of pancreatic cancer patients. Next slide. In Q1, we began developing assays for specific biological molecules that we will be evaluating as potential biomarkers for PCS3117. Our hypothesis is that some of these molecules will be able to predict a patient’s response to PCS3117 and gemcitabine. Thus, giving us away to select patients to be treated with PCS3117 preferentially over gemcitabine. The preliminary assay for initial evaluation should be completed mid-2022. We expect to have developed our roadmaps for the development of PCS3117 for a number of different cancers and targeted populations, such that we can meet with the FDA at the end of this year to discuss the next clinical study for PCS3117. Next slide. In conclusion, you can see that we have successfully moved next generation capecitabine, PCS499 and PCS12852 forward, even with COVID having a serious effect on enrollment for PCS499. We expect by midyear and at the end of the year to have key data on these three trials that will help us design the larger efficacy trials. We also anticipate that all programs will have a roadmap for the various targeted populations along with the potential paths to approval. And lastly, we expect that our interactions and collaboration with the FDA will provide us with more insight into which development path for each drug has the highest probability of demonstrating an FDA approvable benefit risk profile. The last slides are the pipeline background slides that have been presented before in some form. I will not discuss these slides, but they are in the deck to provide more information. This concludes my remarks. I’ll now ask the operator to open the phone lines for Q&A. Operator, can you please pull for questions?
