Extends exclusivity period for TheoremRx

London, UK - ValiRx Plc (AIM: VAL), a life science company focusing on early-stage cancer therapeutics and women's health, announces today it has extended the exclusivity period for TheoremRx Inc. ("TheoremRx"), to complete their financing round and execute the sub-license for VAL201 for use in oncology indications.

Further to the announcement of 17 June 2022, the Company confirms that additional details have been received from TheoremRx regarding the progress of its financing round and strategic plans which are subject to review to the satisfaction of the Company. Meantime, the Company has agreed to extend the period of exclusivity described in the VAL201 Letter of Intent entered into by ValiRx and TheoremRx until TheoremRx has completed its funding round.  The Company has reserved the right to terminate the exclusivity in the event that the board believes sufficient progress is not maintained.

A further update will be made in due course.

The Letter of Intent and proposed sub-license therefore remain non-binding and there is no guarantee that this sub-license will be executed or that it will generate material revenues within the expected timeframe or at all.

Dr Suzy Dilly, CEO of ValiRx commented: "We continue to work closely with TheoremRx and are pleased to have received several items to confirm their progress towards completing their financing round.  In the light of these developments, we are pleased to be able to extend their exclusivity period until this financing is completed.  In the meantime, we continue to work as a team, with ValiRx supporting their development plans, and with TheoremRx providing reciprocal support by devoting their time to our endeavours."

Dr Ken Sorensen, Chairman of TheoremRx stated: "We have appreciated the work carried out so far, and we remain confident of being able to complete our financing round.  VAL201 is an important part of our pipeline of new projects."

About VAL201

VAL201 is a short peptide being studied as a potential treatment for prostate cancer. The peptide structure is inspired by the naturally occurring androgen receptor and is designed to intercept and prevent the binding of the androgen receptor to SRC kinase - an enzyme implicated in cancerous cell growth pathways. By preventing the androgen-mediated activation of SRC kinase, VAL201 can potentially prevent cancerous cell proliferation (or growth) without interfering with other functions of either the androgen receptor or SRC kinase. This precision method, mimicking a natural process, proposes a high specificity of cancer treatment with a lower side effect profile. VAL201 was licensed from CRT (part of CRUK) in 2010 and developed through preclinical development into this clinical trial in patients with advanced prostate cancer. The study was held at University College Hospital (UCLH), London.

About Prostate Cancer

Around 48,500 men are diagnosed with prostate cancer in the UK each year[1]. In men, it is the most common cancer in the UK.  Prostate cancer is most common in older men. On average each year 35 out of 100 (35%) of new cases are in men aged 75 and over.
