Analyst · ROTH Capital Partners. Your line is open
Thank you, Shari, and thank you all for joining our call this morning. Just as I began our last call, I'd like to say that the entire team hopes that you and your families remain healthy in the face of the myriad of challenges presented by the COVID-19 pandemic. Here at GlycoMimetics we've continued our work largely from our homes with minimal disruption to our operations. Although we're happy to report that our scientists have been able to return to our labs on a staggered basis all in compliance with CDC and Maryland state guidelines, we're diligently coordinating our activities to maintain ongoing business operations. Let me begin by saying that the second quarter was a busy and productive one for us. Enrollment continued in our pivotal Phase 3 registration trial evaluating uproleselan in relapsed/refractory AML. The enrollment rate for the quarter was such that we are maintaining our prior guidance. We expect completion of enrollment in the second half of 2021. We also saw a steady progress in our collaborative multicenter registration trial with the National Cancer Institute or NCI where uproleselan is being studied in newly-diagnosed elderly AML patients who are fit for intensive chemotherapy. With respect to rivipansel, we believe our additional analyses of efficacy data represent an opportunity to reassess the potential viability of this drug. We now plan to explore with the FDA whether there's a path forward for this drug as a candidate for treatment of vaso occlusive crisis or VOC in sickle cell disease. We'll now comment on each of these achievements and cover several other highlights as well. First update on uproleselan. We did see an initial slowing in enrollment in our company-sponsored AML trial during the early days of the COVID pandemic. However, enrollment rates recovered well and accordingly we are affirming our prior guidance namely that we expect to complete enrollment in the second half of 2021. We will continue to actively monitor the ongoing impact of the pandemic on patient enrollment and study progress. The clear enthusiasm for our trial among clinicians continues to be high again underscoring uproleselan's potential to provide benefit across a host of clinical endpoints. These include improving chemotherapy outcomes and ameliorating some of the serious adverse events of intensive cytotoxic chemotherapy. You'll remember that there's a second registration trial now underway of uproleselan. This is being conducted by the National Cancer Institute and is treating patients with newly-diagnosed AML. For this trial as well I can report that accruals slowed during the early days of the COVID pandemic the sites are now actively enrolling again. As soon as the NCI publicly shares an update on that trial's enrollment, we'll provide that information to you. While work in the clinics both in our own relapsed/refractory AML trial and in our collaborative NGI trial continues to progress. I'd also like to call attention to the preclinical data we presented at this year's first virtual annual meeting of the American Association of Cancer Research or AACR. At that meeting, we presented animal data that further supports the potential of our compounds in the treatment of AML, specifically co-targeting and inhibition of E-selectin, CXCR4 and FLT3 with GMI-1359 in combination with sorafenib was shown to protect normal hematopoiesis that is blood cell formation and more efficiently reduce leukemia burden compared to sorafenib alone. This resulted in extended survival in the patient-derived sub mutated AML model. Preclinical data also addressed opportunities in the setting of stem cell transplantation. Additionally, new information was presented on the potential of transcriptome profiling to identify those tumor types in patients most likely to benefit from targeted E-selectin inhibition the key mechanism of uproleselan and support of a biomarker-driven approach to treating patients with AML. Further analysis of E-selectin ligand glycosylation genes supports our belief in the prognostic importance of this gene expression signature in AML highlighting the potential use of uproleselan in AML and other hematologic malignancies. Let's now turn to rivipansel. We shared with you in our year-end call Pfizer's decision to return to GlycoMimetics its rights to rivipansel, our investigational drug per vaso-occlusive crisis or VOC and sickle cell disease. The transfer back to GlycoMimetics of these rights and licenses the IND for the clinical development program and the entire data set for the Phase 3 RESET trial is now complete. Over the past few months, we've been actively analyzing the Phase 3 data to determine if there is a potential path forward for this asset in sickle cell disease. We're committed not only to sharing the details of these analyses with the scientific community, but also to defining various potential options if any that could be available to us to carry rivipansel forward. A particular note in June we were able to share the first data glean from in-depth analysis of the RESET study including new data evaluated primary efficacy endpoint. Specifically, patients treated with rivipansel within approximately 26 hours of onset of vaso-occlusive crisis experienced statistically significant improvements in time to readiness for discharge compared to placebo. To remind you the Phase 3 RESET trial evaluated 345 patients who were experiencing acute VOC and required hospitalization for treatment. The patients ranged in age in six years to adult with a mean age of 22 years. The analysis showed that patients treated with rivipansel early in their acute painful episode experienced statistically significant improvement on the primary efficacy endpoint of the p-value of 0.03, a hazard ratio of 0.58 and median improvement compared to placebo of 56.3 hours. In other words, if treatment with rivipansel was initiated early patients receiving rivipansel were ready for discharge over two days earlier and than patients randomized to placebo. Since we're often asked, let me explain that the time to readiness for discharge endpoint was the endpoint specifically agreed to with the U.S. FDA. It reflects achievement of multiple clinical criteria assessing healthcare utilization and the patient's medical improvement prior to leaving a hospital including no longer needing IV opioids, IV hydration or other related treatments. Equally important, we observed that patients treated with rivipansel showed a deep rapid sustained and statistically significant reduction in soluble E-selectin an inflammatory biomarker of acute VOC. We believe this shows that rivipansel has its intended on target biological effect. The effects observed on soluble E-selectin in this trial provides valuable insight into the mechanism for the improvement in the clinical criteria for discharge from the hospital observed in those patients treated early in their acute VOC. Data from the RESET trial additionally demonstrate the favorable safety profile for rivipansel. Safety profile of rivipansel observed in this trial is evaluated in the population with pediatric, adolescents and adult patients bolsters the case for potential risk-benefit value proposition favoring rivipansel. We're exploring various options for rivipansel in this acute treatment setting for which there are no approved drugs and to our knowledge no drugs currently in late-stage development. As part of that process, we intend to discuss these data with the FDA to determine what if any next steps could be taken to carry this program forward in acute VOC. In the interim the supportive efficacy analysis on the new biomarker data will be presented at the September meeting of the Foundation for Sickle Cell Disease Research or FSCDR. FSCDR posted the abstracts on its website FSCDR.org in mid-June and they are available for your review. We've also completed additional analyses on the Phase III RESET trial that further support the potential benefit rivipansel may provide in acute VOC. We hope to publish and/or present these new findings at upcoming medical meetings. In addition to the rivipansel's poster an abstract containing data on GlycoMimetics more selective and highly-potent E-selectin antagonist GMI-1687 has been accepted for an oral presentation by FSCDR for their September meeting. The GMI-1687 abstract includes data from a preclinical model showing that drug candidates potential as a subcutaneously administered treatment for VOC. With rivipansel now back in our own hands, GMI-1687 provides an opportunity for a potential follow-on product with subcutaneous administration. Prior to Pfizer's return to the rivipansel rights, we were prohibited from pursuing this molecule in sickle cell disease. IND-enabling activities are now underway and it's our belief that GMI-1687 could provide an opportunity for patients to be treated at home as soon as the acute pain VOC begins. The opportunity to do so could potentially abort the event before vascular coagulation and potential organ damage occur. Since we now know that early targeted E-selectin intervention can have an impact on acute VOC this asset is uniquely suited to address that need. Needless to say, it's an exciting time at GlycoMimetics. We have two pivotal programs progressing well in AML. The rivipansel rights are returned and additional analyses are completed. We plan to engage in discussions with FDA on rivipansel and our portfolio of novel GlycoMimetics drugs includes multiple candidates that are truly differentiated. Now I'd like to turn to Brian to review both the quarter's financial results and to provide his perspective on our financial situation. Brian?
