Toronto, Ontario--(Newsfile Corp. - August 25, 2022) - PharmaDrug Inc. (CSE: PHRX) (OTCQB: LMLLF) ("PharmaDrug" or the "Company"), a specialty pharmaceutical company focused on the research, development and commercialization of psychedelics and other naturally-derived approved drugs, is pleased to announce that the Company continues to successfully execute on key objectives related to its multiprong psychedelics research and development strategy by generating potential shareholder value through a diversified approach to foundational research, drug development, and near-term translation into clinical studies. The Company's complimentary efforts in psychedelic research all focus on N,N-Dimethyltryptamine (DMT) and undisclosed analogues thereof. Specifically, PharmaDrug continues to capitalize on its formal engagement and collaborative efforts with leading researchers and translational scientists at Johns Hopkins University (JHU), Center for Psychedelic and Consciousness Research, Terasaki Institute for Biomedical Innovation (TIBI) and University of Michigan, through advancement of drug development efforts, human clinical studies, and strengthening of its patent portfolio.

Daniel Cohen, CEO and Chairman of PharmaDrug commented, "With a focused biotech strategy now in place, PharmaDrug can accelerate its push forward in its psychedelic programs. Utilizing bottom up fundamental research and innovation fueled by world class collaborations, the Company plans to continue to find novel uses and unique delivery forms of DMT to treat unmet medical needs."

Collaborative Research Agreement with Terasaki Institute Leads to Discovery of Potential New Treatment for Glaucoma

Based on promising research conducted at Terasaki Institute for Biomedical Innovation (TIBI) the Company is pleased to announce that it has selected its final lead drug candidate from a short list of six DMT analogue molecules and intends to submit a provisional patent in Q4, 2022 detailing the novel uses and dosage forms of its lead candidate, and medical device for the treatment of primary open angle glaucoma (POAG). Lead candidate selection derives from the demonstration of superiority as it relates to in vitro potency in two predictive bioassays, a favorable toxicity profile as well as physical, chemical, and metabolic properties necessary to fabricate a proprietary medical device capable of conveniently delivering sub-psychedelic levels of drug to the front of the eye over a sustained period. With efforts related to discovery and candidate selection now complete, the Company intends to advance its program in POAG by finalizing details of a second sponsored research collaboration with TIBI to undertake 1) mechanism of action studies, 2) optimization of medical device drug release characteristics, 3) in vitro host-species justification studies, 4) evaluation of drug efficacy in an IND-enabling study of POAG with the goal of providing all necessary support to file an investigative new drug (IND) application with the United States Food and Drug Administration (the "FDA") to conduct clinical studies. Under the terms of the existing agreement, the Company owns or co-owns all resulting intellectual property that arises and has an exclusive option to obtain a worldwide, royalty-bearing commercialization license to all rights and title that result from studies conducted within the scope of the sponsored research agreement.

Clinical Research Collaboration with Johns Hopkins University to Evaluate DMT in a Phase 1 Clinical Study

The potential of psychedelic drugs to treat various neuropsychiatric indications is currently being explored in several human clinical trials. The Center for Psychedelic and Consciousness Research located at Johns Hopkins University (JHU) houses one of the largest and most recognized collections of psychedelics researchers in the world. In August of 2021 the Company announced that it had entered into a Clinical Research Collaboration with JHU to investigate the acute and potentially persisting effects of DMT and an undisclosed psychoactive comparator drug. By way of update, the Company is pleased to announce that excellent progress has been made in preparation of the clinical drug supplies and drafting of the IND application is underway and planned for Q4, 2022 submission to the FDA. Consistent with these developments, the Company has opted to extend its clinical research program with principal investigator Dr. Frederick S. Barrett, PhD, Associate Professor of Psychiatry and Behavioral Sciences, and Co-investigators Dr. Sandeep Nayak and Dr. Roland Griffiths; all from the JHU Center for Psychedelic and Consciousness Research.

As previously detailed, the planned clinical study will consist of two parts. The first part will examine dose effects of DMT and the other undisclosed test article. During the second part of the study, healthy subjects will be exposed to a maximum tolerated dose of each drug (as determined in part 1 of the study). During both parts of the study, investigators will characterize any acute and persisting subjective, affective, cognitive, and neural dose-dependent effects for both drugs being evaluated. Much debate exists around the relative potential benefits of micro vs macro-doses for psychedelic compounds. Using a highly controlled approach, the currently planned clinical trial will go some way to answering this important question. Employing an extensive battery of psychological assessment tools, coupled with state-of-the-art functional MRI and EEG the JHU researchers endeavour to develop a more fulsome understanding of how DMT acts in the brain of healthy volunteers; with the ultimate goal of being able to apply this knowledge in tailoring the treatment of serious neuropsychiatric conditions. Under the terms of the agreement, the Company has an exclusive option to obtain worldwide, royalty-bearing commercialization license to all rights, title, and interest that JHU may have or obtain in any invention that results from the clinical study.

This clinical research collaboration builds upon PharmaDrug's existing strategy of focusing on establishing a better understanding of the basic mechanisms by which DMT exerts its effects in the brain and elsewhere in the body. By supporting world class talent with distinct expertise in early discovery and clinical use the Company will be optimally positioned to identify novel applications for DMT and unlock its full therapeutic potential.

PharmaDrug Supports Foundational Research Aimed at Understanding Role of Endogenous DMT

Rounding out the third component of the Company's psychedelic strategy in DMT research and development, PharmaDrug is pleased to announce that it has formally extended its collaboration with Dr. Jimo Borjigin, University of Michigan. Dr Borjigin, in collaboration with the Company has undertaken experiments that aim to provide fundamental understanding related to the mechanisms that regulate the synthesis of endogenous DMT and the potential roles of endogenous DMT in normal, diseased, and altered states of consciousness in a newly created animal model. Notably, Dr. Borjigin was the first to show that the rat brain is capable of synthesizing and releasing DMT at concentrations comparable to known monoamine neurotransmitters and to raise the possibility that similar mechanisms may be operational and vital in human brains. Investing in the foundational research of endogenous DMT production, the Company hopes to leverage expertise and findings to develop novel therapeutic strategies that can be translatable and clinically relevant.
