Analyst · H.C. Wainwright. Please go ahead, sir
Thanks, James. As has been my habit on previous calls, I will begin by providing a high level summary of what we are doing at Caladrius, and then further expand on each of our clinical programs. At Caladrius, we are focused on the development of autologous cellular therapies designed to reverse disease. We have late stage clinical programs underway based on a large database of human clinical data. To date, our therapies have shown signs of effectiveness and durability with a positive safety profile, unlike many allogeneic therapies, and we believe present the possibility of substantial pharmacoeconomic benefit. Most importantly, we remain focused on the development of personalized curative cell therapy products that can restore health and improve quality of life with a single administration of the therapy rather than one that requires frequent re-administration. A CD34 cell therapy technology has led to the development of a therapeutic product candidates designed to address diseases and conditions caused by ischemia a condition in which the supply of oxygenated blood to healthy tissue is restricted. Previously published preclinical and human clinical studies have demonstrated that administration of CD34 positive cells induces an angiogenesis of the microvasculature that is these cells prompt the development of new blood capillaries, thereby contributing to the prevention of tissue death by facilitating blood flow to the area of ischemic insult. We believe that several chronic conditions caused by underlying ischemic injury can be improved through the application of our CD34 cell technology, including, but not limited to coronary microvascular dysfunction or CMD, critical limb ischemia or CLI, Buerger’s disease, diabetic kidney disease or DKD and no option refractory disabling angina or NORDA. I will now speak to each of our development programs kicking off with CLBS16, our promising CD34 cell therapy product for the treatment of coronary microvascular dysfunction. In May of 2020, the company announced the full data results of ESCaPE-CMD trial at the Society for Cardiovascular Angiography and Interventions or SCAI 2020 Scientific Sessions virtual conference, showing a highly statistically significant improvement in coronary flow reserve correlating with symptom relief for patients with coronary microvascular dysfunction after a single intra-coronary injection of single CLBS16. CMD is a disease that continues to be under-diagnosed and potentially afflicts millions annually, a vast majority of whom are female, with no current treatment options. The company is committed to raising awareness this growing women's health crisis and finding an effective treatment and consequently, the company recently initiated and is currently treating patients in a rigorous Phase 2b B clinical trial known as the FREEDOM trial, which to our knowledge is the first controlled regenerative medicine trial in CMD in the United States. Investigator and subject response to the FREEDOM Trial has been favorable and early enrollment proceeded according to plan. However, the continued impact of the COVID-19 pandemic, including the resurgence of cases occurring in select areas throughout the United States, has contributed to a general slowing of enrollment. In addition, further work with investigators and prospective subject feedback led the Company to propose to the FDA amendments to the FREEDOM Trial protocol to enhance the breadth and speed of subject enrollment. These changes included expanding the techniques that are acceptable for diagnosing CMD. Nevertheless, given the uncertainty that persists surrounding the future impact of the COVID-19 pandemic on potential patient recruitment and the accessibility of investigator sites, the Company now projects enrollment completion for the FREEDOM Trial to occur in the third quarter of 2022 with final data based on the 6-month assessment of all subjects expected by the second quarter of 2023. Turning now to CLBS12 known as HONEDRA, in Japan, our product candidate for the treatment of critical limb ischemia and Buerger’s disease, HONEDRA was awarded SAKIGAKE-designation from the Japanese regulatory authorities for the treatment of critical limb ischemia and Buerger’s disease, an orphan-sized subset of CLI. The SAKIGAKE Designation is akin to an RMAT designation in the United States and affords the recipient prioritized regulatory consultation, a dedicated review system to support the development and review process, including the option of a rolling registration submission as well as reduced review time of six months for the registration application once filed. HONEDRA is also eligible for early conditional approval and possibly full approval in Japan based on the compelling nature of the complete data from our ongoing prospective randomized controlled open-label multicenter study in CLI and Buerger’s disease patients, which was designed insight in direct collaboration with the Japanese PDMA. Note that conditional approval of a SAKIGAKE product only requires the demonstration of a trend toward therapeutic effect together with acceptable safety. The Company's registration eligible study of HONEDRA in Japan for the treatment of CLI and Buerger’s disease has shown positive results to-date. The initial responses observed in subjects who have reached an endpoint in this study are consistent with a therapeutic effect and safety profile reported by previously published clinical trials in Japan and the United States. The studies enrollment continues to be slowed by the COVID-19 pandemics impact in Japan, including multiple state of emergency declarations by the Japanese government. However, the Company is encouraged that less than a handful of patients are needed to reach study completion. The exact date of which is impossible to predict given the continuing impact of the pandemic on clinical trials in Japan, while the final outcome of the trial will depend on all data from all subjects, the data to date [Audio Dip] 60% of subjects [Audio Dip] cohort having reached a positive CLI free endpoint, despite a natural history of such patients that predicts continuing disease progression to amputation. Regarding commercialization, our strategy remains to license or partner HONEDRA in Japan. And to that end, our conversations continue with prospective partners and we continue to seek the consummated deal in concert with the completion of the study, if not before. Earlier this year, we were pleased to report that the U.S. FDA granted orphan designation to CLBS12 as a treatment for Buerger’s disease, however, any potential developments in the U.S. will be decided after further discussion with FDA on the requirements for registration, all expected prior to the end of this year. Moving onto our most recently proposed development program, CLBS201 for the treatment of diabetic kidney disease. The Company has prepared an initial development plan for the clinical study of CLBS201, a CD34 investigational product for administration via the renal arteries to slow the deterioration, or, ideally, reverse the decline of renal [Audio Dip] diabetic kidney disease who, although still pre-dialysis, exhibit rapidly progressing stage 3b disease. Progressive kidney failure is associated with attrition of the microcirculation of the kidney. Pre-clinical studies in kidney disease and injury models have demonstrated that protection or replenishment of the microcirculation results in improved kidney function. A Phase 2 proof of concept, randomized, placebo-controlled study for the stage 3b chronic kidney disease patient population is planned to initiate in the next few months. The protocol calls for a six-subject open-label treatment run-in arm in which patients will be treated sequentially, to be completed, evaluated and cleared for continuation by the study’s data safety monitoring board prior to initiating the 40-patient randomized, placebo-controlled, double blinded portion of the trial. The Company is projecting that safety data from the six-subject run-in arm will be completed by the end of the second quarter of 2022. And lastly, OLOGO for the treatment of no option refractory disabling angina or NORDA, as disclosed on previous [Audio Dip] Caladrius acquired the rights to data and regulatory filings, for a CD34 cell therapy program for NORDA that had [Audio Dip]. Based on the clinical evidence from the completed studies that a single administration of OLOGO reduces mortality, improves angina, and increases exercise capacity in patients with otherwise untreatable angina, this product received Regenerative Medicine Advanced Therapy designation from the FDA better known as RMAT. Discussions with the FDA have resulted in a rejection of the Company's efforts to reduce the FDA requirement of a 400 patient Phase 3 study for registration, including an arm of 50 standard of care patients and an arm of 150 placebo patients, despite data showing that the NORDA population is orphan in size. Because enrollment of a study of this magnitude and design is projected to take many years, if executable at all, the Company has decided not to pursue a Phase 3 program for OLOGO on its own, but will continue to seek a partner to execute the study and advance the program. So in closing, we are very pleased with the corporate and development achievements made in the second quarter and first half of 2021. Throughout the balance of the year, we expect to advance our clinical development pipeline and we will strive to execute on a number of important development milestones, more than ever. Our experienced, dedicated and passionate team remains committed to the advancement of our programs as we work to bring innovative treatment options to patients in need. And with that Operator, we're ready to take questions.
