Agreement with Kalos Therapeutics


First project under new strategy to develop pipeline of early stage projects


10 November 2020:


London, UK -  ValiRx (AIM: VAL) a clinical stage drug development company, announces today that it has entered into an agreement with Kalos Therapeutics (Kalos), a US-based private biotechnology company, to evaluate its peptide KTH222 as a drug candidate for treating patients with ovarian cancer. This project underscores ValiRx's new strategy to grow a pipeline of innovative, early-stage projects in the area of oncology and women's health.


Under the terms of the agreement, ValiRx has the right to perform a defined series of preclinical, cell-based assays to consider the benefit of using KTH222 in combination with standard of care treatment, Paclitaxel.  At the conclusion of the estimated six-month evaluation schedule (May 2021), ValiRx has the option to enter a full licensing agreement, with KTH222 anticipated to be integrated into a jointly owned ValiRx subsidiary for further clinical development.


Kalos has completed lead optimisation and proof-of-concept preclinical studies. Kalos will remain actively interested in the programme, contributing scientific expertise during the evaluation period and is expected to be an active partner in the subsequent joint venture.  In return, on entering the evaluation agreement, Kalos has been pledged 10,000 ValiRx shares, subject to approval by shareholders at the 2021 Annual General Meeting of the Company.


Dr Suzy Dilly, CEO of ValiRx commented, "I am delighted to announce this new evaluation agreement with Kalos Therapeutics.  This project is an excellent example of the assets we are looking to acquire; ovarian cancer sits squarely in our portfolio focused on oncology and women's health, and the peptide nature of the drug is within our development expertise.  Importantly, this agreement underscores our new strategy to identify and develop promising early-stage therapies with the aim of progressing such assets to the next stage of development."


George Colberg, CEO of Kalos Therapeutics added, "I'm looking forward to working with the ValiRx team to further our development of KTH222 into ovarian cancer.  Our central ethos at Kalos has always been to develop drugs that are kinder to patients, and we were delighted to find a team with comparable ideals."

Integrating science and business

We connect diverse disciplines across scientific, technical and commercial domains, with the aim of achieving a more streamlined, less costly, drug development process.  We work closely with our selected collaborators and leverage the combined expertise required for science to advance.


Lead candidates from our portfolio are out-licenced or partnered with investors through ValiRx subsidiary companies for further clinical development and commercialisation.


About KTH222

KTH222 is an 8 amino acid peptide that has been developed from the study of Atrial Natriuretic Peptide (ANP).  By considering the anti-cancer properties of the ANP protein, Kalos have produced a short peptide that represents a fragment of ANP designed to confer the therapeutically beneficial properties of ANP in an anti-cancer treatment.


In ovarian cancer treatment we are evaluating whether in combination with Paclitaxel, or similar standard of care drugs, a patient could get an equivalent, or potentially longer lasting, benefit with a lower dose of Paclitaxel.  This is expected to result in better tolerability of the Paclitaxel treatment, which in turn could allow patients to remain on treatment for a longer period; potentially improving the time for resistance to develop, and conferring continued benefit after Paclitaxel treatment is halted. In addition, further beneficial effects including the reduction of ascites (a type of swelling that is particularly debilitating in ovarian cancer) are expected due to the mechanism of action of KTH222.


About Kalos Therapeutics

Kalos is pursuing a multi-phase strategy to reorient today's therapeutic approach to cancer patients while driving changes to transform therapeutic approaches for unmet and rare medical conditions. Kalos has a lead compound KTH 222, which is more promising than "standard of care" drugs with difficult to treat cancer tumors. Kalos has entered the fight against COVID-19 with a novel peptide therapeutic approach for the most vulnerable of patients.


Kalos is devoted to treating the unmet needs of people living with incurable diseases while doing so with less toxic and debilitating side effects than current standard-of-care treatments; thereby improving the quality of life for the patient and their families. Kalos believes that by leveraging nature and the body's mechanisms, they have created new, safer approaches to cancer and diseases that affect the eye. Kalos has several applications for animal health based on its eight-amino-acid and a 15-amino-acid drug KTV-111. .
