VAL201 Clinical Trial Full Data Results
Full dataset confirms VAL201 is a safe and well-tolerated drug candidate
Company to host webcast for investors on
The dataset provides a complete breakdown of the full data of safety and tolerability as well as evidence for encouraging disease impact as observed during the clinical trial. This data will be used to formulate the Clinical Study Report and to report the results on the www.clinicaltrials.gov database. Additional detailed analysis of the results will form the basis of peer-reviewed journal publications.
The full dataset is available to download on the Company website, https://www.valirx.com/our-pipeline/val201 .
Key details of the findings:
· Twelve patients were recruited according to the criteria of having incurable, locally advanced or metastatic prostate cancer with rising PSA (Prostate-Specific Antigen) on three consecutive samples and absent or very mild prostate cancer-related symptoms.
· The demographics and a detailed breakdown of the patients recruited is provided in the download.
· The headline results released in the Company announcement on
· The PSA data, a recognised surrogate of disease progression, shows two patients seeing a decrease in PSA during their treatment period, one of which maintained the decrease throughout the trial. An analysis of the doubling time of patients shows a statistically significant (p<0.05, two-tailed Wilcoxon Signed-Rank test for paired samples) increase in PSA doubling time comparing pre-treatment doubling time to post-treatment doubling time. The PSA doubling time would be expected to be unchanged if the treatment was having no impact, so an increase in doubling time demonstrates a slowing rate of growth of PSA levels.
· The tumour response data demonstrates that patients did not have an increase in metastatic lesions during the treatment period, and that metastatic lesions already present did not grow at all in two out of three patients, suggesting a positive influence of VAL201 on the disease.
Safety and Tolerability
The further breakdown of the safety data confirms the well tolerated nature of the drug.
Additionally, the initial pharmacokinetic analysis supports the safety profile in confirming the drug is processed and cleared from the body in the manner expected.
The Company expects to publish the data on the National Institute of Health's (NIH) public database ClinicalTrials.gov, as well as produce research papers for peer-reviewed publications.

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),
About the VAL201-001 clinical trial
The clinical trial: "A Phase I/II, Dose Escalation Study to Assess the Safety and Tolerability of VAL201 in Patients with locally Advanced or Metastatic Prostate Cancer and Other Advanced Solid Tumours" opened to recruitment in
Patients were scheduled for treatment of a once weekly injection of VAL201 in 3 week cycles for a maximum of 6 cycles. A total of 12 patients received at least 1 dose of VAL201.
Patients were eligible if they were: Adult men (over the age of 18) with incurable locally advanced or metastatic prostate cancer who had relapsed following radiotherapy treatment, are in 'watchful waiting' or where a policy of intermittent hormone therapy had been decided. Patients were expected to have no or only mild symptoms relating to their prostate cancer. (ClinicalTrials.gov identifier: NCT02280317)
