RespireRx Pharmaceuticals Inc. Announces Entry into Option Agreement to License GABA(A) Receptor Allosteric Neuromodulator Intellectual Property from the UWM Research Foundation, Inc.
— 9:00 AM ET 03/04/2020
Glen Rock, N.J., March 04, 2020 (GLOBE NEWSWIRE) -- RespireRx Pharmaceuticals Inc. ( RSPI) (“RespireRx” or the “Company”), a leader in the research and development of ampakines for a variety of central nervous system disorders (CNS disorders) and cannabinoids for the treatment of sleep-related breathing disorders, is pleased to announce that on March 2, 2020, the Company and the UWM Research Foundation, Inc. (“UWMRF”), an affiliate of the University of Wisconsin-Milwaukee entered into an option agreement (“Option Agreement”) pursuant to which RespireRx has a six-month option to license the identified intellectual property pursuant to license terms substantially in the Form of Patent License Agreement that is attached to the Option Agreement as Appendix I (“Form of Patent License”). A copy (partially redacted) of the Option Agreement with Appendix I has been filed by the Company on Form 8-K with The Securities and Exchange Commission and may be accessed at the SEC’s website available at www.sec.gov. The Option Agreement identifies United States Patents 9,006,233, 9,597,342, and 10,259,815 and Canadian patent application serial No. 2979701, and all other patents and patent applications in lineage with these priority applications, including PCT, utility, divisional, continuation, continuation-in-part, and any corresponding patent applications filed in countries foreign to the United States of America and Canada with priority dates prior to the effective date of the License Agreement. The Company has paid the $2,500.00 purchase price for the option, which expires six months from March 2, 2020. The option agreement identifies certain conditions precedent to its exercise. One of those conditions is a contractual commitment of at least $1 million of aggregate financing (as such term is defined in the Option Agreement) to the Company. Other conditions include the submission to UWMRF of an acceptable development plan, satisfactory responses to reasonable UWMRF requests for information and the receipt of appropriate approvals by each party. For a more complete description of the Option Agreement, refer to the complete Form 8-K filing and its Exhibits.
Prior to the expiration of the Option Agreement, the parties intend to enter into a Patent License Agreement substantially in the form of Appendix I to the Option Agreement. The Form of Patent License calls for the Company to be able to practice the licensed subject matter. RespireRx would be required to provide annual development plan updates. The Form of Patent License also calls for the Company to remit to UWMRF, in installment payments, past patent costs, annual license maintenance fees beginning on the second anniversary, clinical milestone payments upon the dosing of the first patient in a Phase II clinical trial, upon the dosing of the first patient in a Phase III clinical trial, and upon the approval of a new drug applications (“NDA”) with the Food and Drug Administration (“FDA”). Royalties on net sales would also be due to UWMRF. In addition, in the event of sub-licenses to third-parties, the Company will owe a portion of sub-license revenue to UWMRF. In lieu of an upfront payment upon exercise of the option and at the effectiveness of the license agreement and consistent with our view that our relationship with the University of Wisconsin is as much a partnership as a license, UWMRF has been granted an appreciation right associated with the neuromodulator program if sold or assigned equal to 4.9 percent of the consideration received.
As described in our previous press release of February 12, 2020, the Company intends to re-structure the corporation by creating two separate business units. In that press release, we described our plans for creating a new, stand-alone pharmaceutical cannabinoid company (“Newco”) with a focus on developing a new formulation of dronabinol for the treatment of obstructive sleep apnea and to exploit opportunities that may result from our new patent filing. Building upon our ampakine platform as a foundation, we also are planning the establishment of a second business unit, which we currently call Project Endeavor, that will focus on developing novel classes of drugs that fall under the broad category of “neuromodulators”. The term neuromodulators refers to drugs that do not act directly at the receptor sites for brain neurotransmitters, but instead act at accessory sites that enhance (Positive Allosteric Modulators – “PAMs”) or reduce (Negative Allosteric Modulators – “NAMs”) the actions of neurotransmitters at their primary receptor sites. Ampakines act as PAMs at the AMPA receptors for glutamate, the major excitatory neurotransmitter in the brain. Through an extensive series of translational studies from the cellular level up to human Phase 2 clinical trials, selected ampakines have demonstrated target site engagement and positive results in patients with Attention Deficit Hyperactivity Disorder (see below).
The compounds described in the patents that are the subject of the Option Agreement and Form of Patent License Agreement with UWMRF act as PAMs at certain sub-type specific receptors for GABA, the major inhibitory transmitter in the brain. Certain of these compounds have shown impressive activity in a broad range of animal models of refractory/resistant epilepsy and other convulsant disorders, as well as in brain tissue samples obtained from epileptic patients. Epilepsy is a chronic and highly prevalent neurological disorder that affects millions of people world-wide. While many anticonvulsant drugs have been approved to decrease seizure probability, seizures are not well controlled and, in as many as 60-70% of patients, existing drugs are not efficacious at some point in the disease progression. We believe new drugs are clearly needed. In addition, these compounds have shown positive activity in animal models of migraine, trigeminal pain, anxiety and other areas of interest. Because of their GABA receptor sub-type specificity, the compounds have a greatly reduced liability to produce sedation, motor incoordination, memory impairments and tolerance, side effects commonly associated with non-specific GABA PAMs, such as benzodiazepines.
“While several milestones will need to be achieved in order to effect the license agreement, primarily the availability of sufficient capital, and the consolidation of the ampakine and GABA modulator platforms, Project Endeavor is intended to be one of the major CNS programs in the field of neuromodulation. We eagerly look forward to working with our partners at UWMRF and scientific collaborators, including Dr. James Cook and others at the University of Wisconsin-Milwaukee and Dr. Jeffrey Witkin of the Indiana University School of Medicine,” said Dr. Arnold Lippa, Executive Chairman of the Board, Chief Scientific Officer and Interim CEO.
About RespireRx Pharmaceuticals Inc. ( RSPI)
RespireRx Pharmaceuticals Inc. ( RSPI ) is a leader in the development of medicines for respiratory disorders and CNS indications, with a focus on obstructive sleep apnea, attention deficit hyperactivity disorder (ADHD), spinal cord injury and other neurological conditions. The Company owns and has exclusive rights to patents and patent applications for certain families of chemical compounds that claim the chemical structures, formulations and their uses in the treatment of a variety of disorders, as well as claims for novel uses of known drugs.
Cannabinoids. RespireRx is developing dronabinol, ?-9-tetrahydrocannabinol (?-9-THC), a synthetic version of the naturally occurring substance in the cannabis plant, for the treatment of OSA, a serious respiratory disorder that impacts an estimated 29.4 million people in the United States according to the American Academy of Sleep Medicine (“AASM”), published in August 2016. OSA has been linked to increased risk for hypertension, heart failure, depression, and diabetes, and has an annual economic cost in the United States of $162 billion according to the AASM. There are no approved drug treatments for OSA.
Pending the outcome of an intended meeting with the FDA, RespireRx believes that it will be able to commence a pharmacokinetic study for a to-be-developed new formulation followed by a Phase 3 clinical study for the treatment of OSA with the new formulation. Because dronabinol is already FDA approved for the treatment of AIDS related anorexia and chemotherapy induced nausea and vomiting, the Company further believes that its re-purposing strategy would only require approval by the FDA of a 505(b)(2) new drug application (“NDA”), an efficient regulatory pathway that allows the use of publicly available data.
Ampakines. The second platform of proprietary medicines being developed by RespireRx are ampakines, which act to enhance the actions of the excitatory neurotransmitter glutamate at AMPA glutamate receptors. Several ampakines, in both oral and injectable forms, are being developed by the Company for the treatment of a variety of CNS disorders. In clinical studies of respiratory function, 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 certain orphan disorders, such as Pompe Disease, Rett’s Syndrome and perinatal respiratory distress, certain ampakines have been shown to improve breathing function. Although the Company does not intend to pursue respiratory indications for ampakines at the present time, we view these findings as proof of target engagement and signals of clinical efficacy.
Ampakines have shown potential as possible therapeutic agents for the treatment of certain neuropsychiatric and neurological disorders. Ampakines have demonstrated positive activity in animal models of ADHD, results that have been extended translationally into statistically significant improvement of symptoms observed in a Phase 2 human clinical trial of CX717 in adults with ADHD. At present, the major pharmacotherapies available for ADHD are made up of two types of drugs. Stimulants, such as amphetamine, rapidly produce robust effects, but suffer from side effects typical of stimulants, including tolerance, dependence, withdrawal and abuse. For these reasons, stimulants are scheduled by the FDA. Non-stimulants, such as Straterra® (atomoxetine) tend to be less effective than stimulants, with a much longer (approximately 4 – 8 week) latency to onset of action. In a number of animal and human studies, CX717 and other ampakines did not display any stimulant properties typically associated with drugs like amphetamine. In the Phase 2 ADHD clinical trial, statistically significant therapeutic effects were observed within one week. Therefore, we believe ampakines may represent a novel, non-stimulant treatment for ADHD with a more rapid onset of action than alternative non-stimulant treatment options.
RespireRx owns certain composition of matter and use patents and patent applications with respect to ampakines CX1739, CX717 and other ampakines.
