What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are GI-102, or Pasritamig. The registry lists allocation as randomized. The purpose of this clinical trial is to measure 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).
They plan to enroll about 107 people at 6 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
Official title (unrewritten)
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)
Interventions: GI-102, Pasritamig
Primary outcome (registry wording): Incidence and nature of DLTs (Safety run-in phase)
