Phase 2 clincal trials for CX1739 for opioid-induced respiratory depression and dronabinol for Obstructive Sleep Apnea are on schedule to conclude and report results in the coming months."
Dr. Manuso continued, "To fund our clinical trial activities, we successfully raised additional equity capital during the three months ended June 30, 2016. We are continuing our efforts to fully fund our drug development activities, including our clinical trial programs, and to strengthen our balance sheet."
Dr. Manuso concluded, "We encourage those interested in learning more about the current clinical landscape for treating respiratory diseases to follow continuing developments at RespireRx."
Developments during the Three Months Ended June 30, 2016
Key developments during the three months ended June 30, 2016 included the following:
- The Company conducted a Phase 2A human subject clinical trial at the Duke University School of Medicine to evaluate the Company's lead oral compound, CX1739, for the prevention of respiratory depression caused by remifentanil, a potent opioid, while maintaining its desired analgesic effects. The double-blind, placebo-controlled dose-ascending Phase 2A clinical trial completed dosing in June 2016 and was formally completed on July 11, 2016. The Company expects to complete a preliminary top-line analysis of the respiratory data by the end of September 2016 and to issue a final report on the results of the clinical trial by the end of December 2016.
- A Phase 2B clinical trial evaluating dronabinol in 120 patients with Obstructive Sleep Apnea is being led by University of Illinois researchers. The University of Illinois has indicated that recruitment for this clinical trial was completed during the second quarter of 2016. Final research results are expected to be published in the fourth quarter of 2016.
- The Company raised aggregate gross proceeds of approximately $115,000 from the sale of units comprised of common stock and warrants and approximately $762,000 from warrant exchange transactions effected in conjunction with the Note Exchange Agreements and Unit Exchange Agreements.
- The Note Exchange Agreements resulted in the elimination from the Company's balance sheet of convertible notes with a principal amount of $303,500, plus accrued interest of $40,993.
- All outstanding shares of Series G 1.5% Convertible Preferred Shares (including accrued but unpaid dividends) were automatically and mandatorily redeemed via conversion into shares of common stock on April 17, 2016.
- The Company presented at and otherwise participated in a number of investor conferences.
Research and Development Overview
RespireRx is a leader in the development of medicines for respiratory disorders, holding exclusive licenses and owning patents and patent applications for certain families of chemical compounds that claim the chemical structures and their uses in the treatment of a variety of disorders. The Company also controls rights and associated patents covering claims for novel uses of known drugs.
RespireRx has a pipeline of medicines in Phase 2 clinical trials focused on a variety of different breathing disorders. Clinical development advancements in the area of respiratory disorders, particularly drug-induced respiratory depression and sleep apnea, have created multiple opportunities for the ultimate commercialization of the Company's medicines.
RespireRx's pharmaceutical candidates in development, which are derived from two platforms, are as follows:
- One platform of medicines being developed by RespireRx is a class of proprietary compounds known as ampakines, which act to enhance the actions of the excitatory neurotransmitter glutamate at AMPA glutamate receptors. Several ampakines, in both oral and injectable form, are being developed by the Company for the treatment of a variety of breathing disorders. In clinical studies, select ampakines have shown preliminary efficacy in central sleep apnea and in the control of respiratory depression produced by opioids, without altering the opioid analgesic effects. In animal models of orphan disorders, such as Pompe Disease, spinal cord damage and perinatal respiratory distress, it has been demonstrated that certain ampakines improve breathing function. The Company's compounds belong to a new class that does not display the undesirable side effects previously reported for other ampakines.
- The other platform is the class of compounds known as cannabinoids, including, in particular, dronabinol. Under a license agreement with the University of Illinois, the Company has rights to patents claiming the use of cannabinoids for the treatment of sleep-related breathing disorders. In a double-blind, placebo-controlled, dose-ascending Phase 2A clinical study conducted by the Company, dronabinol produced a statistically significant reduction in the Apnea-Hypopnea Index, the primary therapeutic end-point, and was observed to be safe and well-tolerated in a group of patients with Obstructive Sleep Apnea.
Information with respect to current clincal trials involving RespireRx's pharmaceutical candidates is as follows:
- The Company filed an Investigational New Drug ("IND") application with the U.S. Food and Drug Administration ("FDA") in September 2015 to conduct a double-blind, placebo-controlled, dose-ascending Phase 2A clinical trial in approximately 18 subjects to determine the ability of orally administered CX1739, the Company's proprietary lead ampakine, to prevent the respiratory depression produced by remifentanil, a potent opioid, without altering remifentanil's analgesic properties. The clinical protocol was designed to evaluate the safety and efficacy of three escalating doses of CX1739 versus placebo when administered prior to remifentanil, with respiration, analgesia and a number of other clinical measures being taken after administration of both drugs. The commencement of this clinical trial was subject to resolution of two deficiencies raised by the FDA in its clinical hold letter issued in November 2015. These issues were satisfactorily resolved in early 2016, and the FDA removed the clinical hold on the Company's IND for CX1739 on February 25, 2016, thus allowing for the initiation of the clinical trial. During March 2016, upon receiving unconditional approval from the Institutional Review Board of the Duke Clinical Research Unit, this Phase 2A clinical trial at Duke University School of Medicine was initiated, with the dosing portion of the clinical trial completed in June 2016 and the clinical trial formally completed on July 11, 2016. The Company is currently working with the Duke University clinical research team to analyze the data collected. The Company expects to complete a preliminary top-line analysis of the respiratory data by the end of September 2016 and to issue a final report on the results of the clinical trial by the end of December 2016.
- The University of Illinois and three other research centers are currently investigating dronabinol in a potentially pivotal, six week, double-blind, placebo-controlled Phase 2B clinical trial in 120 patients with OSA. The University of Illinois has indicated that recruitment for this clinical trial was completed during the second quarter of 2016. Final research results are expected to be published in the fourth quarter of 2016. This clinical trial is fully funded by the National Heart, Lung and Blood Institute of the National Institutes of Health. The Company is not managing or funding this clinical trial.
