The in-house research pipeline comprised 4 evaluation programmes with assets from Barcelona University, Stingray Bio, Imperial College and Dundee University as well as our SPV Cytolytix. The pipeline represented a range of early stage, small molecule and peptide-based assets with a combination of validated, novel and unknown mechanisms of action. Assets at this stage of development have a high attrition rate, up to 90%. Development of in-licensed assets, for example Cytolytix, through preclinical development and into Investigational New Drug (IND) enabling studies, take significant time and resources so a high attrition rate should be expected with earlier stage programmes. A key consideration is to generate a balanced portfolio with scientifically robust data and a strong commercialisation potential and, going forward, we are applying a strict set of criteria for selection and progression of evaluation assets. Evaluation agreements with Barcelona and, post period Imperial, have been terminated despite initially promising data generated by Inaphaea, as they did not meet these criteria. Whilst the Dundee evaluation did not meet a key decision point for in-licensing in 2024, £50,000 grant funding was secured through Queen Mary Impact fund, supported and a one-year extension to the evaluation agreement was signed to develop precise mechanism of action for this asset. The Stingray evaluation was completed on time and, whilst a key decision point was not reached, we are in further negotiation to progress this asset under a slightly different model.
Several new evaluation programmes remained under discussion throughout 2024 with the first signed post period in January 2025. The agreement with Altus Therapeutics is based on repositioning an established CB2 agonist in oncology and, in a first for ValiRx, bringing new formulation capabilities. A key aspect of the evaluation programmes is to leverage Inaphaea's in-house capabilities. Inevitably, some of the work will require external support, either through our partner network or from additional Contract Research Organisations which can add significant costs. This is particularly true for later stage, more developed projects which may be lower risk but require higher initial investment. In order to deliver a more balanced portfolio, we are exploring shorter, more nimble evaluations over a 3-6-month period where we can add significant value through our PDC biobank or through support of external preclinical work on a shared risk, costs plus basis. Under this type of arrangement, ValiRx would be compensated for work performed if the asset is returned and subsequently licensed.
