A Phase 1b/2, Open-label, Multi-center Study to Evaluate the Anti-cancer Activity, Safety and Tolerability of GI-102 (CD80-IgG4 Fc-IL2v3) in Combination With Pasritamig [T-CELL-Redirecting Agent Targeting Human Kallikrein 2 (KLK2)] in Patients With Metastatic Castration-resistant Prostate Cancer (mCRPC) Who Progressed on Previous Novel Hormonal Therapy (NHT) (JET-201)
The purpose of this clinical trial is to evaluate the safety, tolerability, and preliminary anti-cancer activity of GI-102 in combination with pasritamig in adult men with metastatic castration-resistant prostate cancer (mCRPC) whose cancer has progressed after previous treatment with a novel hormonal therapy (NHT).

Incidence and nature of DLTs (Safety run-in phase)
Ramy czasowe: From Day -14 to Cycle 1 Day 22 (35 days)
|
A DLT is defined as a clinically significant AE (classified according to the NCI CTCAE version 6.0) or significant laboratory abnormality that occur during the DLT assessment periods, and is considered by the Investigator to be related to the study drug(s). |
From Day -14 to Cycle 1 Day 22 (35 days)

Incidence, nature, and severity of AEs graded according to CTCAE v6.0 (Safety run-in phase)
Ramy czasowe: Up to 2 years
|
An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as AEs. All AE events will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 6.0. |
