Post-Period Highlights

· Placing in September 2017 with existing and new investors successfully raised £0.5 million

· VAL101 - ValiRx recently reported much improved technical efficacy and commercially viable efficient manufacturing capabilities and that preliminary results for the optimised second generation of the VAL101 molecule are demonstrating gene silencing levels that are similar to the original structure. VAL101's late pre-clinical studies to be accelerated in preparation for the compound's entry into the clinic.

Oliver de Giorgio-Miller, Non-Executive Chairman of ValiRx, commented:

"We have seen considerable progress across our therapeutic portfolio in the last 6 months, adding value to the company's assets and bringing us closer to the point where our clinical programmes for VAL201 and VAL401 will deliver meaningful data and will bring the Company closer to finding a partner. I am pleased with the momentum generated as we move towards clinical developmental milestones and potential value inflection points for VAL401 and VAL201 as we approach the year-end. "

"Our portfolio of therapeutic drugs collectively address multi-billion dollar markets and meet significant unmet need. I therefore strongly believe that ValiRx and its assets offer investors or joint venture partners an increasingly attractive and investable proposition as we strengthen our position among frontrunners in the fields of personalised and precision medicine."

Notes for Editors

About ValiRx

ValiRx is a biotechnology oncology focused company specialising in developing novel treatments for cancer and associated biomarkers. It aims to make a significant contribution in "precision" medicine and science, namely to engineer a breakthrough into human health and well-being, through the early detection of cancer and its therapeutic intervention.

The Company's business model focuses on out-licensing therapeutic candidates early in the development process. By aiming for early-stage value creation, the company reduces risk considerably while increasing the potential for realising value. The group is already in licensing discussions with major players in the oncology field.

ValiRx's two classes of drugs in development, which each have the potential for meeting hitherto unmet medical needs by existing methods, have worldwide patent filings and agreed commercial rights. They originate or derive from World class institutions, such as Cancer Research UK and Imperial College.

Until recently, cancer treatments relied on non-specific agents, such as chemotherapy. With the development of target-based agents, primed to attack cancer cells only, less toxic and more effective treatments are now possible. New drugs in this group-such as those in ValiRx's pipeline-promise to greatly improve outcomes for cancer patients.

The Company listed on the AIM Market of the London Stock Exchange in October 2006 and trades under the ticker symbol: VAL

CHAIRMAN'S STATEMENT FOR THE HALF YEAR ENDED 30 JUNE 2017

Trialist reports on VAL201 and VAL401 in clinical trials for the treatment of Advanced Prostate Cancer and Non Small-Cell Lung Cancer remain buoyant as evidence of their safety and tolerability continues to mount and as evidence of their efficacy emerges.

VAL201

What makes VAL201 a potentially major breakthrough therapeutic treatment of Advanced Prostate Cancer is its novel mechanism of action. A number of studies have demonstrated that inhibiting Src activity strongly reduces prostate cancer growth. VAL201 specifically targets the association of androgen receptor with Src, a protein that is important in tumour cell proliferation without suppressing other hormone induced activities. This is in complete contrast to current therapies, which in addition to abolishing the receptor-dependent signalling pathways also inhibit the receptor's other functions leading to impotence, tumour flare and loss of bone mass. No serious adverse events have been reported in the ongoing clinical studies at University College London Hospital ("UCLH") and VAL201 continues to show signs of clinical activity in patients with advanced prostate cancer.

VAL401

The period under review has been a defining period in terms of VAL401's clinical development and the expansion of our drug pipeline. VAL401 is a re-formulation of anti-psychotic drug Risperidone into an orally administered gelatin capsule. The compound has shown pronounced anti-cancer properties in pre-clinical testing and has moved quickly through its Phase ll efficacy trial involving patients with locally advanced or metastatic non-small cell lung cancer, who have typically 6 - 12 months of life expectancy. First dosing of patients commenced in November 2016. Since then, further patients and clinical trial sites have been recruited and opened respectively, with initial pharmacokinetic analysis showing that the presence and levels of the active drug and known metabolite in blood samples, are as expected. In June 2017, we announced that the trial had completed its recruitment phase and that ValiSeek had decided there was no requirement to enrol further patients. Since then, data processing and analysis of the results to date has commenced and results from the preliminary datalock are expected this month. The trial remains on track to be completed by year-end following which further data processing and analysis will be performed, thereby defining the clinical activity of VAL401 and its potential positive effect on patient quality of life.

GeneICE/VAL101

Our GeneICE "rebellious gene" technology has shown continued good progress in its late pre-clinical phase, with the programme currently benefitting from a second Eurostars grant for up to €1.6 million. Rebellious genes are genes that are overexpressed when they should not be or are erroneously expressed, e.g. in cancers, inflammatory conditions, Alzheimer's and autoimmune diseases. ValiRx's proprietary GeneICE technology enables the design of compounds for selective silencing of specific genes. The GeneICE lead compound has been designed against a gene expressing Bcl-2 protein, which has been implicated and associated with various cancers. Pre-clinical work during the period under review has been conducted with our partners, DKFZ, Heidelberg and Pharmatest in Finland, to generate a commercially viable molecular structure for VAL101, because whilst the molecule worked in its first generation and that Bcl-2, the gene associated with cancer, was seen to reduce and that cancer cell death occurred, the molecule's structure and manufacture however required optimisation for commercial production. ValiRx was pleased to report earlier this month, much improved technical efficacy and commercially viable efficient manufacturing capabilities and that preliminary results for the optimised second generation of the VAL101 molecule are demonstrating gene silencing levels that are similar to the original structure. As such, ValiRx intends to accelerate VAL101's late pre-clinical studies in preparation for the compound's entry into the clinic.

VAL301

VAL301 is derived from our lead compound, VAL201 and is currently in late-stage pre-clinical development as a non-invasive, effective treatment for the non-cancerous, but hugely debilitating gynaecological condition, Endometriosis. Earlier pre-clinical work on VAL201 has highlighted the compound's potential to protect uterine tissue from the oestrogenic effects that give rise to Endometriosis, with minimal impact on bone density or fertility, which are major drawbacks frequently encountered with the current commonly used drugs for this condition. Our focus now is to complete the pre-clinical package and arrive at the optimal formulation so that the Company obtains the necessary regulatory approvals to enter VAL301 into a clinical trial in 2018.

Outlook

We have seen considerable progress across our therapeutic portfolio in the last 6 months, adding value to the company's assets and bringing us closer to the point where our clinical programmes for VAL201 and VAL401 will deliver meaningful data and will bring the Company closer to finding a partner. I am pleased with the momentum generated as we move towards clinical developmental milestones and potential value inflection points for VAL401 and VAL201 as we approach the year-end.

Our portfolio of therapeutic drugs collectively address multi-billion dollar markets and meet significant unmet need. I therefore strongly believe that ValiRx and its assets offer investors or joint venture partners an increasingly attractive and investable proposition as we strengthen our position among frontrunners in the fields of personalised and precision medicine.
