Analyst · this time. Thank you, ladies and gentlemen, this concludes today's event. You may disconnect at this time and have a wonderful day. Thank you for your participation
Thank you, Jim. Good evening. Thank you for joining us today. During my time with you today, I plan to highlight what we've accomplished so far in 2021 in our drug development programs, then briefly share what you should be expecting over the next 6 to 12 months. I will not be covering all the details on each slide, but the slides will be posted on our website if you want to study them more. Let's go to our first slide. I'm sure that most of you seen this slide before, it describes the criteria that we use to select the drug for our pipeline. But also describe the fundamental approach that Processa uses corporately. We make small bets on potentially large wins in order for Processa to achieve an asymmetrical risk reward or market cap to market opportunity. Both our regulatory science approach and our corporate approach, is to evaluate the benefit risk of everything and determine how to improve the benefit risk profile to our advantage. That's why we are a drug development company not a drug discovery company, and while we have 5 criteria that must be met for a drug to be in our pipeline. Today, I will only briefly talk about the first 3 criteria. The first criteria is the drug must provide treatment to patients that need better treatment options than what already exists. These are patients with an unmet medical need condition, who need something to improve their survival and are improve their quality of life. Second, there must be some evidence of clinical efficacy for the drug in the target population of patients. This means that a drug or a drug with similar pharmacology must have demonstrated some efficacy in the target population. And third, the regulatory science approach to develop the drug must provide a more efficient path demonstrated better benefit risk profile, compared to existing therapy options for the targeted patient population. Next slide. Now, let's look at what we've accomplished in our drug development programs over the last 3 months. Our overall development goal was to move the drugs closer to FDA submission. And we accomplish that, as can be seen in the red box describing the present status of our pipeline. For 499, and its Phase 2B trial, 2 patients have been enrolled in the study and we have 3 of 9 sites recruiting patients, with the other 6 sites being initiated over the next few weeks. For 12852 and its Phase 2A trial, we plan to submit the IND before the end of September. During the second quarter, we also in-licensed another cancer drug PCS3117. This drug already has demonstrated some efficacy and treatment resistant pancreatic cancer patients. To define, which patients would do better on this drug and other existing pancreatic cancer drugs, we have begun to select lab, who can develop specific biomarkers that will identify the patients more likely to respond to 3117 compared to existing chemotherapy. PCS6422, our second drug for the treatment of cancer is used in combination with capecitabine to treat colorectal cancer and as enrolled its first patient and its first cohort. Other patients are in the screening waiting room, these patients will be screened and if appropriate enrolled in a few weeks after we obtain some clinical data on our first patient. We expect to have all our sites up before the end of September. And the last cancer drug, PCS11T, we are identifying and evaluating contract manufacturing organizations, they can manufacturing this drug. Next slide. Let me quickly review our 499 Phase 2B drug, where which we have FDA orphan designation. NL is an unmet medical need condition that initially appears to be a dermatological condition, but is a condition that affects the skin and tissues below the skin. NL can last from months to years with complications such as infections and amputation. Also, it's occurring in about 30% of the patients in conclusive diagnosis can only be accomplished through a biopsy, where the histological presentation is different than other ulcers, such as diabetic ulcers. The NL ulcers can occur naturally over the clinical course, or they can occur from contact trauma to the lesion, because the skin becomes more fragile and brittle. More importantly, natural complete healing of moderate-to-severe ulcers than the first 1 to 2 years after onset, encourage them less than 5% of these patients. Currently, there is no FDA approved treatment for NL and no standard of care. And all drugs used off-label are inadequate, because of dose limiting side effects, which prevents the drug to be given at a high enough dose to possibly see significant efficacy. This includes a drug called pentoxifylline, or as I often call it, PTX. PTX does work in closing the ulcers of some patients, but side effects limit the dose that can be administered. Given there are 22,000 to 55,000 ulcerative NL patients in the U.S. The U.S. potential market is approximately $1 billion. Next slide. 499 is similar to PTX, but not identical. It's the deuterated analog of one of the major metabolites of PTX. It has the identical same 7 metabolites of PTX, and it hits the exact same pharmacological targets that the pharmacokinetics of 499 and metabolites are different after 499 administration resulting in a better efficacy and safety profile than PTX. 499 and its metabolites affects 6 different pharmacological pathways, which directly affect 6 of the 7 pathophysiological changes know to occur in NL. The results in 499 in these patients, it acts like a multiple drug cocktail, although all the effects are coming from 499 and its metabolites. The safety profile 1.8 gram per day at 499 is better than the safety profile of 1.2 grams per day of PTX, as shown in toxicology studies as well as Phase 1 and Phase 2 clinical studies. In addition, we found that in our Phase 2A NL trial, complete wound closure was achieved with the 1.8 gram per day of 499 in the only 2 patients who presented with ulcers, and each patient had contract trauma ulcers on the drug and those ulcers also closed within 1 month. The picture shown on the left is one of these patients prior to receiving 499. You can see the ulcers circled, after treatment the ulcers are completely closed as seen in the picture on the right. The bottom of this slide is from our pipeline slide reminding everyone that we hope to complete the interim analysis for 499 in the first half of 2022. We hope to complete the study in the second half of 2022. And then we plan to meet with the FDA for an end of Phase 2 meeting to grant a design of a pivotal Phase 3 Special Protocol Assessment trial to begin in 2023. Next slide. The other non-cancer drug in our pipeline is PCS12852. This drug is a 5HT4 agonist that is more potent and more specific to the 5HT4 receptor than any other drug approved by FDA or presently being investigated. The target indication for the drug is the treatment of gastroparesis. And the clinical trial the drug has been shown to significantly increase gastric motility and requirement to treat gastroparesis, while also having a better side effect profile than other 5HT4 agonists. Next slide. Given that the only approved drug for gastroparesis, and drugs used off label for gastroparesis, so all have serious side effects, limiting their use. The market for gastroparesis is a wide open market with enormous potential sales. Fortunately, there's been a lot of preclinical and clinical work done in 12852, so that we expect to submit a Phase 2A IND in September and enroll our first patient in the first half of 2022. Final analysis of this Phase 2A study should be completed in the end of 2022 for the beginning of 2023. The first of our oncology drug to discuss is the one that we recently acquired PCS3117. Next slide. 3117 is our most advanced cancer chemotherapy agent and development. It has a patent life to 2036 and FDA orphan designation for the treatment of pancreatic cancer. 3117 is an analogue of endogenous nucleotide cytidine, and an analogue of the cancer drug gemcitabine, which has sales of greater than $800 million in the U.S. Gemcitabine is presently used as first-line therapy for metastatic pancreatic cancer and non-small cell lung cancer, as well as use the second-line therapy for other types of cancers. Unfortunately, 55% to 85% of the patients receiving gemcitabine are inherently resistant to gemcitabine, or acquire resistance while on the drug. The resistance can exist or occur because of multiple biological reasons, 2 of the causes for resistance, which may 3117 an attractive alternative to gemcitabine. Our first dCK, the activation enzyme from gemcitabine is down regulated, resulting in less activation gemcitabine. The activation enzyme for 3117 is dCK2, which is different than dCK. And in many patients dCK2 exist in cancer cells more than normal cells. Secondly, RRM1 and RRM2 with the ribonucleotide reductase enzyme is up-regulated, this results in an increase in endogenous cytidine nucleotide, which then compete with the active gemcitabine cancer killing nucleotide. For 3117, this up-regulation of RRM1 and now RRM2 actually stimulates the production of the 3117 cancer killing nucleotides. In addition, 3117 not only follow the same gemcitabine pharmacological pathway, affecting DNA cancer cell apoptosis, but it also affects RNA and DNA methyltransferase, resulting in cancer cell apoptosis following a different pathway than gemcitabine. It is important to note that the efficacy of 3117 has already been demonstrated in a small number of gemcitabine-resistant pancreatic cancer patients. Next slide. Our development program will be based on our overall mission to improve the benefit/risk profile over existing treatment options. For 3117, this means targeting patients who do not or probably will not respond to gemcitabine. We believe this can be done through the development and refinement of assays for a few biological molecules or biomarkers to identify which patients are more likely to respond to or activate 3117 over gemcitabine. Over the next 6 to 12 months, we hope to complete our biomarker assay development, such that we will be able to evaluate the assay in a Phase 2B biomarker pancreatic cancer study initiated in the second half of 2022 and then move to the pivotal Phase 3 FDA Special Protocol Assessment trial in 2023 or 2024. Next slide. The second oncology targeted drug is PCS6422, a chemotherapy modifier of the widely used drug capecitabine or Xeloda, the oral form of 5-FU, one of the cornerstone cancer chemotherapy drugs since the 1960s. 6422 has the potential to improve the benefit/risk profile of capecitabine, by altering the metabolism of capecitabine which results in a decrease in the side-effects, while potentially improving the progression-free survival of patients, making this a combination, a potential $1 billion market for just the treatment of metastatic colorectal cancer. If we include other cancers where capecitabine is first or second line therapy, the market for 6422 and capecitabine is a multiple billion dollar market. Next slide. Preliminary evidence presently exists demonstrating that the administration of 6422 with 5-FU related drugs like capecitabine will improve not only the safety, but also the efficacy profile for these 5-FU related compounds. Using a regulatory science approach, we have also found potential biomarkers that will help to identify those patients who will most likely benefit from this targeted therapy over present treatments. From our Phase 1B trial, we expect to obtain information to better design a Phase 2B or an adaptive design Phase 3 trial in the near future. Over the next 6 to 18 months, we expect to complete an interim analysis of the first 2 cohorts in the fourth quarter of 2021, then define our maximum tolerated dose in the second half of 2022. And begin our Phase 2B or our pivotal Phase 3 trial in 2023 or 2024. Next slide. This slide presents just the timeline for the key clinical milestones for all 5 drugs in our pipeline. I've already mentioned these milestones, but this slide provides a summary of the milestones over the next 6 to 18 months in a timeline format. Next slide. We accomplished a lot in the first and second quarter, but we expect to accomplish even more over the next 6 months. This last slide summarizes what we expect to accomplish in development over the next 6 months. First, a complete enrollment of patients for the interim analysis of 499. Second, IND clearance for 12852 in Gastroparesis. Third analysis of Cohort 1 and 2 in the 6422 Phase 1B dose escalation study. Fourth, initial development of the 3117 biomarker assays. Fifth, we are presenting at the World Orphan Drug Congress on August 25 to 27. And lastly, we'll be presenting at Oppenheimer Fall Healthcare Life Science and MedTech Conference in September 20 to 23. It's important to note that with the $20.8 million of cash that Jim mentioned, that we have - as of June 30, 2021, we have enough cash to support our efforts through 2023, while completing the 499 Phase 2B trial, the 12852 Phase 2A trial, the identification of the maximum tolerated dose of capecitabine when administered with 6422 in the Phase 1B trial, and the development of the 3117 biomarker assays. I hope this earnings call has given everyone a better understanding of what we've accomplished over the last 3 months as well as the first 6 months in 2021. As you can see, we also have a lot to do over the next 6 months. And we believe the value of Processa will become more apparent as we start seeing interim results. And with each program, one step closer to FDA approval. That concludes my remarks. I'll now ask the operator to open the phone lines for Q&A. Operator, can you please poll for questions?
