Analyst · Ladenburg. Your line is now open
Thank you, Jason, and thank you to everyone dialing in to our conference call today, particularly, all of you who are joining us for the first time. The third quarter in recent weeks were yet another exciting period for Salarius as we continue to implement our strategy to build a multi-pronged approach to investigating seclidemstat in cancers were LSD1 is known to be effective. In summary, during the third quarter in recent weeks, Salarius increased the number of sarcoma clinical trial sites, completed enrolment in the Initial Ewing Sarcoma Combination Therapy Safety Lead-in Cohort, enrolled additional patients in the myxoid liposarcoma and FET-rearranged sarcoma cohort and established a research partnership with the Cancer Epigenetics Institute at Fox Chase Cancer Center. In addition, Nationwide Children's Hospital presented data at an important medical conference demonstrating seclidemstat's differentiated mechanism of action resulting in unique anti-cancer activity. And finally, we received $2.7 million from the Cancer Prevention Research Institute of Texas and Selarius was added to the FTSE Global Microcap Index. Now. It was a busy quarter and has been a busy past few weeks, so there's a lot to review today. But before we get into details, I would like to take a moment to provide some background to those of you on today's call who are new to the Selarius story. For those of you who are not new to Selarius, please indulge me where I have some perspective to our newest listeners. Our lead asset called Seclidemstat is an oral drug a tablet actually that inhibits a widely validated cancer target LSD1. Targeting the LSD1 enzyme has been an area of interest in Cancer Research for over a decade. The LSD1 plays a key role in the development of progression of numerous cancers. Seclidemstat is a novel reversible LSD1 inhibitor with a differentiated mechanism of action that granted broad activity across several cancer types compared to other LSD1 inhibitors being researched in clinical trials. LSD1 carries out its cancer promoting effects by causing dysregulated gene expression which results from the misreading of genetic code in the nucleus of the cells. A good analogy for appreciating dysregulated gene expression and on an analogy I've used before is baking. If we follow a recipe precisely and then mix the correct ingredients in the right amounts, the result is a successful birthday cake. This regulated gene expression is essentially the misreading of our genetic recipe. All the right ingredients are there, however, they are in the incorrect quantities. And that occurs in the context of living cells, meaning our genetic code is misread, it can meet the development and progression of cancer. Seclidemstat is designed to correct this dysregulation and we believe the research presented during the third quarter affirms and confirms this capability. As we've discussed our recent accomplishments and future plans, you'll hear me describe a two-pronged development strategy; speed to market represented by our sarcoma program and expand the market represented by our hematologic or blood cancer program; and our continuing research into other large market opportunities. With that as the back drop, let's discuss the accomplishments in third quarter in recent weeks. Seclidemstat is currently in two clinical programs spanning five different patient groups and is being studied as a single agent therapy and in two different combination therapies. Our lead clinical program which we refer to as our Sarcoma Program, is a Phase ½ clinical trial with three patient arms. The first arm is investigating seclidemstat in combination with chemotherapies, topotecan and cyclophosphamide to the treatment of Ewing sarcoma. The second and third arms are exploring seclidemstat as single agent therapy for the treatment of myxoid liposarcoma and other FET-rearranged sarcomas. During the third quarter, Selarius added five new clinical trial sites to our sarcoma trial increasing the number of active sites to that are now supporting sarcoma enrollment to 13 total sites. These new sites include the Cleveland Clinic, Fox Chase Cancer Center, Oncology Consultants of Houston, Virginia Cancer Specialists, and Washington University in St. Louis. These 13 sites provide a good mix of both pediatric and adult sarcoma centers of excellence. We're also actively completing the contracting process with several additional cancer centers which we anticipate bringing online it's clinical trial sites by year end. Patient enrollment in the sarcoma clinical trials accelerating, we believe due to the increased number of active clinical trial sites that I just discussed and the positioning of seclidemstat for use in combination with topotecan and cyclophosphamide or TC for the treatment of relapsed/refractory Ewing sarcoma. As we have mentioned previously, the TC therapy is a common second and third line treatment for Ewing sarcoma. And adding seclidemstat to TC therapy presents an easy integration into a common treatment regimen used earlier in the patient's treatment paradigm. In addition, as we've previously reported, in a common Ewing cell line, seclidemstat and TC demonstrated anti-cancer synergy. Meaning, that one plus one equals more than two in anti-cancer activity. In summary, we've added more clinical trial sites able to add seclidemstat to a commonly used second and third line therapy or the addition of seclidemstat to this therapy shown to be synergistic. I mean, one plus one equals more than two in any cancer activity in treatment or experiments. We believe these factors are all positively influencing enrollment across the sarcoma trail. We are also pleased to report that the initial Combination Therapy Safety Lead-in Cohort for reviewing sarcoma trial arm has completed enrolment and we expect the seclidemstat recommended Phase 2 dose and TC combination to be underway by early 2022. We look forward to providing potential clinical data readouts later this year and throughout next year. All-in-all, we are very pleased with our clinical process and our clinical progress. During the quarter, we were also pleased to report the establishment of a research partnership with the Cancer Epigenetics Institute at Fox Chase Cancer Center. The research is to be conducted in the Laboratory of Dr. Johnathan Whetstine, the institute's director, and would help identify additional indications and potential biomarkers for seclidemstat. Other ongoing prestigious research partnerships include Nationwide Children's Hospital, which recently presented research showcasing seclidemstat's unique ability to inhibit LSD1's non-enzymatic functions leading to anti-cancer activity in FET-rearranged sarcomas. And the MD Anderson Cancer Center which activated an investigator initiated clinical trial to study seclidemstat in hematologic blood cancers in myelodysplastic syndrome MDS and chronic myelomonocytic leukemia or CMML. We believe this widespread interest in seclidemstat is due to the drugs unique and potentially advantageous properties. Seclidemstat employs a differentiated dual mechanism of action that appears to granted activity across several cancer types compared to other LSD1 inhibitors. We believe the seclidemstat has the ability to not only inhibit the enzymatic activity of LSD1 but to more robustly inhibit the scaffolding properties of LSD1 compared to other LSD1 inhibitors. This scaffolding properties of LSD1 have high relevance in several cancer types including solid tumors in large commercial markets. This ability to inhibit the scaffolding properties of LSD1 was recently underscored by research conducted by Dr. Emily Theisen at Nationwide Children's Hospital. They represented at a Cancer Research Conference last month, indicates that seclidemstat's robust scaffolding inhibition is essential towards any cancer activity in FET-rearranged sarcoma. In fact, seclidemstat demonstrated potent activity across cell lines, while in inactive control agent and in irreversible LSD1 inhibitor demonstrated minimal or no activity against the same cell lines. This means, that in FET-rearranged sarcoma cell lines, seclidemstat worked, wherein irreversible LSD1 inhibitor did not work. Based upon all these news, you can continue to understand why we at Salarius are extremely excited by seclidemstat's overall progress and potential. Before I shift topics and discuss the near-term future, I would like to ask Mark Rosenblum, Chief Financial Officer, to discuss our strong financial foundation which is enabling all of this progress. Mark, over to you.
