About RespireRx Pharmaceuticals Inc.

RespireRx Pharmaceuticals Inc. is a leader in the development of medicines for respiratory disorders, with a focus on sleep apneas and drug-induced respiratory depression.  During 2018, the Company plans to meet with FDA to discuss its Phase III clinical trial program to test the safety and efficacy of dronabinol for the treatment of OSA.  The Company owns patents and patent applications, and holds exclusive licenses, for certain families of chemical compounds that claim the chemical structures and their use in the treatment of these and other disorders.

RespireRx’s pharmaceutical candidates in development are derived from two platforms, as described below. 

The first platform is the class of compounds known as cannabinoids, 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 (AHI), the primary therapeutic end-point, and was observed to be safe and well-tolerated in a group of patients with OSA.  Investigators at the University of Illinois and Northwestern University have completed their investigation of dronabinol in a potentially pivotal, six week, double-blind, placebo-controlled Phase 2B clinical trial in 56 patients with OSA.  This study was fully funded by the National Heart, Lung and Blood Institute of the National Institutes of Health.  The Company did not manage or fund this clinical trial.

The second platform of medicines being developed by RespireRx is a class of proprietary compounds known as ampakines that act to enhance the actions of the excitatory neurotransmitter glutamate at AMPA glutamate receptor sites in the brain.  Several ampakines in both oral and injectable form are being developed by the Company for the treatment of a variety of breathing disorders.  In a Phase IIA clinical trial testing CX-1739 for drug-induced respiratory depression, this medicine was shown to control respiratory depression produced by remifentanil, a potent opioid, without altering its analgesic effects. In another Phase IIA clinical trial, CX-1739 demonstrated preliminary efficacy in controlling central sleep apnea.  Various ampakines have demonstrated improved breathing function in animal models of orphan disorders such as Pompé Disease, spinal cord damage and perinatal respiratory distress.  The Company’s compounds belong to a new class of ampakines that do not display undesirable side effects previously reported by earlier generations of ampakines.

Clinical Trial Plans for 2018 - Phase III Clinical Trial Plans for Development of Dronabinol

As reported previously, RespireRx announced positive results for the PACE (Pharmacotherapy of Apnea by Cannabimimetic Enhancement) trial conducted by Dr. David Carley, Dr. Phyllis Zee and their colleagues at the University of Illinois at Chicago and Northwestern University, respectively. The PACE trial, a Phase 2B study of dronabinol for the treatment of OSA, clearly demonstrated that dronabinol significantly improved the primary outcome measures of AHI, daytime sleepiness as measured by the Epworth Sleepiness Scale (“ESS”) and overall patient satisfaction as measured by the Treatment Satisfaction Questionnaire for Medications (“TSQM”).  Based on these results, RespireRx will engage with FDA to agree upon the next steps in connection with the initiation of a pivotal Phase III clinical trial program testing the safety and efficacy of dronabinol in the treatment of obstructive sleep apnea.

Clinical Trial Plans for 2018 - Phase II Trial of CX1739 in Central Sleep Apnea

Pending additional financing and/or strategic relationships, the Company plans to conduct a Phase II, multiple dose clinical trial investigating the ability of CX1739 to improve breathing in patients with central sleep apnea.  Of particular interest will be to look at patients undergoing chronic opioid treatment.  In these patients, central sleep apnea is a major risk factor for opioid over-dose.

Other Potential Clinical Indications for Ampakines

While developing potential applications for respiratory disorders, RespireRx has retained and expanded its ampakine intellectual property and data with respect to neurological and psychiatric disorders and is considering developing certain indications, pending additional financing and/or strategic relationships. As an example, based on positive results from a Phase II clinical trial of CX717 in patients with Attention Deficit Hyperactivity Syndrome (ADHD), RespireRx has filed patent applications claiming the use of ampakines for the treatment of ADHD and is seeking support for further clinical development in this area.  In addition, animal studies conducted in collaboration with Dr. David Fuller and his colleagues at the University of Florida have demonstrated the ability of our lead ampakines to significantly improve breathing in animals with spinal cord injury. The Company believes that these results reflect a more general process whereby the ampakines might improve the motor nerve activity of a number of systems. While additional animal studies are planned at the University of Florida, the Company is also planning, pending additional financing, to conduct a Phase 2 clinical trial investigating the ability of our lead ampakines to improve breathing and motor function in spinal cord injury patients.

Comments by the Company’s President and Chief Executive Officer

Dr. James S. Manuso, commented, “We look forward to advancing the many initiatives RespireRx is undertaking throughout the course of 2018.  Now that the Company is Phase III-ready with respect to the final clinical and regulatory development of dronabinol for the treatment of OSA, commercialization and potential partnering plans may be initiated.  With dronabinol’s Phase III trial on the horizon, along with two Phase II ampakines in development, there are numerous strategic and operational milestones on the calendar.  In 2018 we will continue to focus on the clinical and regulatory development of the Company’s two proprietary platforms for addressing unmet needs in the sleep apnea and opioid-induced respiratory depression markets. In addition, we will continue to support the scientific research and pre-clinical development upon which our company is based.  I look forward to reporting to you our progress in the months ahead”
