Tryp Therapeutics Announces Publication of International PCT Patent Application for Intravenous Delivery of Psilocin and Psilocybin


Enables a potentially scalable model for large-scale deployment of psychedelic treatments

Company to host investor update on Tuesday, October 4e

KELOWNA, British Columbia, Oct. 03, 2022 (GLOBE NEWSWIRE) — Therapeutic TrypInc. (CSE: TRYP) (OTCQB: TRYPF) (“try“or the”Company“), a clinical-stage biotechnology company focused on developing psilocybin-based compounds for diseases with unmet medical needs, announced today that the World Intellectual Property Organization (WIPO) has published its application patent application (PCT/IB2022/052347) covering the intravenous administration of psilocybin and psilocin. The PCT application, titled “Improved Methods for the Use of Psychedelics” extends and strengthens the intellectual property related to the company’s development of TRP -8803, an IV formulation of psilocin, which will be administered in conjunction with psychotherapy.

The patent application includes a unique and proprietary formulation and delivery system to enhance the positive effects of psilocybin and psilocin in particular, while significantly reducing the limitations of dosed psilocybin by other routes of administration, including oral, nasal and sublingual. Oral administration, while convenient, presents several limitations and challenges that TRP-8803 can address, including:

Control the onset delay of the psychedelic experience

  • Oral administration of psilocybin may take 1-2 hours to induce the psychedelic state; IV infusion can reduce this time period to less than 30 minutes.

Manage the duration of the psychedelic experience

  • With oral administration, the psychedelic state, once started, can last 6 to 8 hours, a heavy burden for the patient and the two psychotherapists; IV administration allows the practitioner to manage the duration of the psychedelic state and potentially shortens the overall duration to 1-2 hours.

Achieve clinically validated blood levels of psilocin

  • When administered orally, the bioavailability of psilocybin may be reduced due to first-pass metabolism in the liver. Psilocybin is a pro-drug that must be converted into psilocin, the active molecule that crosses the blood-brain barrier and induces the psychedelic state. These factors contribute to varying blood levels of psilocin, which may be too low or too high. High blood levels are associated with side effects, while low blood levels of psilocin can reduce effectiveness; IV administration allows for more precise dosing that achieves optimal blood levels of psilocin, improving the likelihood of achieving clinical endpoints and efficacy while maintaining safety.

Personalize the psychedelic experience

  • Intravenous administration offers more control over the experience, allowing the treating psychotherapist to increase or decrease both the strength and duration of the psychedelic experience. Conversely, if the patient experiences a side effect, the clinician can discontinue administration of the drug, an option not available with oral administration.

With these benefits, in particular the ability of TRP-8803 to reduce time spent with healthcare professionals in clinical settings, the company believes there is a clear path to wider commercial acceptance and use of TRP-8803. in conjunction with psychotherapy. Oral psychedelics have been widely introduced for use in the treatment of depression, PTSD, OCD, and other conditions, most notably by Tryp Therapeutics and its TRP-8802 programs. The Company plans to leverage its current clinical studies using TRP-8802 for the treatment of binge eating disorder and chronic pain to improve TRP-8803’s chances of success, with the additional goal of provide value to indications beyond those that Tryp is currently pursuing. .

Jim Gilligan, CEO of Tryp Therapeutics, said: “The oral administration of psilocybin has provided valuable advances in the combined use of psychedelics and psychotherapy, but oral therapies also have recognized limitations. We are excited to introduce the unique and exclusive IV delivery of TRP-8803, which we believe can change the landscape of psilocybin therapies.

“In addition to providing the clinician with greater control over the psychedelic experience, from the initiation of the psychedelic experience, to the achievement of targeted blood levels, to a controlled duration of the experience, TRP-8803 also allows for a shorter overall clinical session.Our ability to reduce the in-clinic experience from 8 hours to approximately 2 hours is not only attractive to patients, we also expect it will create a more scalable model for the broad and effective deployment of psychedelic treatment, not just for the indications we are focused on but other indications as well. We remain focused on expanding our patent portfolio as we continue to develop new, evolving, psychedelics and psychotherapeutics for broader indications and with the publication of the PCT, we look forward to discussing the merits of TRP-8803 with collaborators and investors.

Robin Carhart-Harris, Ph.D., Chair of the Scientific Advisory Board of Tryp Therapeutics, commented, “By enabling rapid initiation and termination of the psychedelic experience, as well as providing highly refined control over the depth and the duration of this experiment, I believe that TRP-8803 has very strong potential to change the paradigm of treatment for fibromyalgia and binge eating, as well as certain types of depression, pain, and obsessive-compulsive disorder.
