ClinicalTrials.gov ID: NCT06458712
What this study is testing
What is DSB2455?
DSB2455 is an investigational medicine, being studied as a potential treatment for advanced cancers (breast, ovarian, mcrpc, pancreatic ductal adenocarcinoma (pdac), brain mets) with specific mutations (homologous recombination deficiency).
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Open label, multi-centre, Phase Ia/b adaptive design study with an initial 2-stage Dose Escalation Phase followed by a Dose Expansion Phase.
- Phase 1: an early, usually small safety study
