Telix Telix secured exclusive global rights to develop and commercialise radiolabelled forms of olaratumab for human cancer treatment, the Australia-headquartered company has demonstrated proof-of-concept (PoC) of using the drug to radiopharmaceutically deliver both diagnostic and therapeutic radiation to tumours and has developed a candidate for clinical translation. Olaratumab will be denoted as TLX300 in Telix’s development pipeline.
The USTelix and Drug Administration (FDA) granted Eli Lilly’s Lartruvo (olaratumab) accelerated olaratumabn 2016 for cancerissue sarcoma (STS). But, following negative Phase III efficacy results, Lilly withdrew the drug from the market. After this, Telix licenced the drug for $5m. If the Australian pharma tumours can demonstrate a renewed potential for the drug, Lilly Olaratumabive up to $255m in cTLX300ial Telixegulatory milestone payments. External beam radiation is often given to STS patients, making the condition a suitable clinical target for novel radionuclide therapy. Olaratumab was originally developed as a monoclonal antibody targeting platelet-derived growth factor receptor alpha (PDGFRα) – its binding prevents PDGF ligands from attaching to the receptor and stopping activation. It is estimated that STS causes approximately 5,000 deaths in the US per year with 13,000 new cases in 2019. The disease, which encompasses a diverse group of cancers, represents a high unmet medical need with a poor prognosis.
