A Study of [225Ac]Ac-AKY-2519 in Patients With Metastatic Castration-Resistant Prostate Cancer (BActinium-1)
BActinium-1: A Phase 1b, Multicenter, Open-label Study to Evaluate the Safety and Efficacy of Intravenous Administration of B7-H3 Radiopharmaceutical ([225Ac]Ac-AKY-2519) in Metastatic Castration-Resistant Prostate Cancer
調査の概要
状態
詳細な説明
This Phase 1b study consists of a dose escalation portion and a backfill portion. The dose escalation portion will investigate ascending doses of [225Ac]Ac-AKY-2519 across two cohorts enrolling in parallel:
- Cohort A: participants with metastatic castration-resistant prostate cancer (mCRPC) with NO prior exposure to 177Lu-PSMA-617 (PLUVICTO™) and
- Cohort B: participants with metastatic castration-resistant prostate cancer (mCRPC) with prior exposure to 177Lu-PSMA-617 (PLUVICTO™)
The backfill portion may enrich in two select dose levels from each cohort (Cohort A: mCRPC 177Lu-PSMA-617 (PLUVICTO™)-naïve; Cohort B: mCRPC 177Lu-PSMA-617 (PLUVICTO™)-experienced) to gather further information on the safety and efficacy and to determine the recommended phase 2 dose (RP2D) for each cohort.

Occurrence of adverse events by severity and occurrence of serious adverse events (SAEs) in participants who received [225Ac]Ac-AKY-2519
時間枠:Up to 30 days following last administration of [225Ac]Ac-AKY-2519
|
An AE is defined as any untoward medical occurrence in a participant administered study drug, which does not necessarily have to have a causal relationship with the study drug.
The number of patients experiencing an AE and the number of patients experiencing an SAE will be reported.
Up to 30 days following last administration of [225Ac]Ac-AKY-2519

Occurrence of dose-limiting toxicity (DLT) in mCRPC participants with and without prior 177Lu-PSMA-617 exposure
時間枠:From first administration of [225Ac]Ac-AKY-2519 to the end of Cycle 1 (each cycle is 28 days)
|
Dose-limiting toxicities (DLTs) is defined as any predefined AE occurring during the DLT observation period, except those that are clearly and incontrovertibly due to extraneous circumstances.
The number of patients who experience a DLT will be reported separately for each cohort and by dose level within each cohort.
