This is an open label, multi-drug, biomarker-directed, multi-centre, multi-arm, Phase 1b study in patients with muscle invasive bladder cancer (MIBC) (urothelial) who have progressed on prior treatment. This study is modular in design, allowing evaluation of the safety, tolerability, pharmacokinetics and anti-tumour activity of multiple agents as monotherapy and as combinations of different novel anti-cancer agents. The study will consist of a number of study modules (sub-studies), each evaluating the safety and tolerability of a specific agent or combination.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
AstraZeneca (AZN) is the sponsoring company for this trial. BiotechSign currently grades this company F (16/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
