Oxford Cannabinoid Technologies Holdings plc

("OCTP" or the "Company")

MHRA and REC 2 approval of Phase I Clinical Trial Application

OCTP is pleased to announce that the Medicines and Healthcare Products Regulatory Agency ("MHRA") and the Wales Research Ethics Committee 2 ("REC 2") have approved the Company's combined Phase I clinical trial application for OCTP's lead drug candidate, OCT461201.

This Phase I first-in-human clinical trial is being conducted in the UK in healthy volunteers, with a single ascending dose protocol. The trial is being conducted by Simbec Research Limited, part of Simbec-Orion Group Ltd ("Simbec-Orion") and aims to demonstrate the safety and tolerability of OCT461201, whilst also providing pivotal information on its pharmacokinetic profile, to confirm its value as a potential drug.

Participant enrolment will begin immediately, and the trial is expected to be completed during Q3 2023. The trial is being funded entirely from OCTP's existing resources.

Growing global opportunity

OCT461201 is a selective cannabinoid receptor type 2 agonist which has shown potential as an effective therapy for chemotherapy induced peripheral neuropathy ("CIPN") as well as irritable bowel syndrome ("IBS"). The global market for CIPN alone is currently valued at US$1.61bn and is forecast to reach US$2.37bn by 2027.

Commenting on the MHRA and REC 2 approval, Clarissa Sowemimo-Coker, Chief Executive Officer of OCTP, said:

"We are absolutely thrilled to have passed this very significant milestone. Getting OCT461201 into the clinic so soon after our listing is a huge achievement and is a fitting testament to the hard work and dedication of both OCTP's talented team and our external partners, Aptuit (Verona) SRL, a subsidiary of Evotec SE, and Simbec-Orion. We are moving ever closer to achieving our core aim of improving the lives of patients living with debilitating pain, whilst also, ultimately, delivering value for shareholders.

"This is an important step for the Company and part of our broader strategy which currently incorporates four drug development programmes. We believe that our portfolio approach and extensive library of derivatives continue to provide numerous routes to commercialisation."
