AstraZeneca opens VECTRA-01, a Phase 3 test of alpha-emitter AZD2265 in prostate cancer after beta-emitter therapy

The 670-patient global trial pits an actinium-225 PSMA radioligand against standard of care in men who have already received a beta-emitting radioligand.

AstraZeneca has begun enrolling VECTRA-01, a Phase 3 randomised controlled study of AZD2265 (also known as FPI-2265), an actinium-225 (²²⁵Ac) alpha-emitting PSMA-I&T radioligand therapy, in PSMA-positive metastatic castration-resistant prostate cancer (mCRPC). The trial is now recruiting, with a study start recorded as 4 May 2026.

The design targets a population that has run out of established options. Eligible men must already have been treated with at least two cycles of a PSMA-directed beta-emitting radioconjugate — the class that includes ¹⁷⁷Lu-PSMA — alongside prior taxane chemotherapy and a prior androgen-receptor pathway inhibitor (ARPI). PSMA positivity is confirmed by ⁶⁸Ga-PSMA-11 or ¹⁸F-DCFPyL PET/CT. Prior alpha-emitting radioligand therapy is excluded, though prior radium-223 is permitted.

Trials Today

Phase 3 VECTRA-01 (AZD2265 / 225Ac-PSMA-I&T, mCRPC) — Recruiting; alpha-emitter PSMA radioligand vs SOC after prior beta-emitter, taxane and ARPI; ~670 patients; dual primary rPFS and OS.
Phase 3 PRECISE-HD (pridopidine, Huntington's disease) — Newly registered; 400 patients not on antidopaminergics; primary is 52-week change in composite cUHDRS.
Phase 3 QUILT-2.023 (nogapendekin alfa inbakicept, 1L NSCLC) — Terminated; sponsor registry note states no active subjects, no efficacy results posted (enrolled 102).
Phase 3 Atezolizumab + standard HER2 therapy, 1L HER2+ mBC (NRG/NCI) — Terminated for poor accrual (190 enrolled); posted PFS 52.3% vs 40.5% is a numerical, underpowered signal only (CIs overlap, no HR).
Phase 2/3 Peri-operative nivolumab + ipilimumab, esophageal/GEJ adenocarcinoma (NCI) — Suspended after enrolling 278; registry summary gives no reason, so cause is unconfirmed. Watch item.
