A Study of [177Lu]Lu-A9-0631 and [225Ac]Ac-A9-0642 With [68Ga]Ga-A9-6217 or [177Lu]Lu-A9-0631 Imaging in GRPR+ Solid Tumors
A Phase 1-1b Study to Evaluate the Safety, Efficacy, and Dosimetry of [177Lu]Lu-A9-0631, [225Ac]Ac-A9-0642, and [68Ga]Ga-A9-6217 in Participants With GRPR+ Tumors

Descripción detallada
This is a multicenter, open-label Phase 1-1b study of [177Lu]Lu-A9-0631 and [225Ac]Ac-A9-0642 in subjects with Gastrin-Releasing Peptide Receptor (GRPR) expressing locally advanced, unresectable or metastatic solid tumors.
The study consists of two parts (Phase 1 and 1b).
Phase 1 is the dose escalation portion of the study. The aim of the Phase 1 is to evaluate the safety and tolerability as well as the normal organ and tumor dosimetry of [177Lu]Lu-A9-0631 and [225Ac]Ac-A9-0642, and to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D).
Phase 1b will be the dose expansion portion of the study. The aim of the Phase 1b will be to further evaluate the safety, efficacy, and normal organ and tumor dosimetry of [177 Lu]Lu-A9-0631 and [225Ac]Ac-A9-0642 administered at the RP2D in subjects with (1) Locally advanced, unresectable, or metastatic HR+/HER2- breast cancer; (2) Locally advanced, unresectable, or metastatic prostate cancer; (3) Locally advanced, unresectable, or metastatic CRC; and (4) Other locally advanced, unresectable, or metastatic GRPR-positive solid tumors.

Periodo de tiempo: From the first dose of study drug up to the End of Treatment (30 days after the last dose)
|
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 in Part 1 will be reported.
|
From the first dose of study drug up to the End of Treatment (30 days after the last dose)
|
|
Phase 1: Number of Patients with Dose-Limiting Toxicities (DLTs).
Periodo de tiempo: Up to 28 days following first study treatment
|
DLTs is defined as any predefined AE occurring during the DLT observation period.
|
Up to 28 days following first study treatment
|
|
Phase 1: Maximum tolerated dose (MTD)
Periodo de tiempo: Up to 28 days following first study treatment
|
Incidence of dose-limiting toxicity (DLT) per dose level of [177Lu]Lu-A9-0631 and/or [225Ac]Ac-A9-0642.
