Evaluation of IGM-7354 in Adults With Relapsed and/or Refractory Cancer
Study Details
Study Description
Brief Summary
This study is a first-in-human (FIH), Phase 1, multicenter, open-label study to evaluate the safety, tolerability, and PK of IGM-7354 in participants with relapsed and/or refractory tumors. The study design consists of a dose-escalation stage and dose-expansion stage. Study participation will consist of a 28-day screening period, a treatment period, and a safety follow-up period 90-days after the last dose.

Phase 1 |
Detailed Description
Patients will be enrolled in two stages: a dose-escalation stage and an expansion stage. The escalation stage will investigate single agent IGM-7354 safety and tolerability in patients with relapsed and/or refractory solid tumors. The dose expansion serial biopsy cohort will assess the intra-tumoral PD changes related to the activity of IGM-7354.
IGM-7354 will be administered intravenously (IV).

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: IGM-7354 Single-Agent Dose Escalation IGM-7354 will be administered intravenously as a single agent. |
Drug: IGM-7354
IGM-7354 is a PD-L1-targeted cytokine that is designed to regulate T and natural killer cell activation, proliferation and promote their anti-tumor effects

Outcome Measures
Primary Outcome Measures
- To evaluate the safety and tolerability of IGM-7354 in participants with cancer including estimation of the MTD or MAD [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Incidence of treatment-emergent AEs, SAEs, and DLT per NCI CTCAE v5.0
Secondary Outcome Measures
- Area Under the Curve (AUC) of IGM-7354 [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Area Under the Curve (AUC) of IGM-7354 as a single agent
- Clearance (CL) of IGM-7354 [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Clearance (CL) of IGM-7354 as a single agent
- Volume of distribution (V) of IGM-7354 [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Volume of distribution (V) of IGM-7354 as a single agent
- Maximum Plasma Concentration (Cmax) of IGM-7354 [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Maximum Plasma Concentration (Cmax) of IGM-7354 as a single agent
- Objective Response Rate (ORR) [Study duration of approximately 29 months]
The ORR is defined as the percentage of participants who achieve a confirmed complete response (CR) or partial response (PR) per RECIST 1.1 as assessed by investigators
- Duration of Response (DoR) [Study duration of approximately 29 months]
For participants who demonstrate confirmed CR or PR, duration of response is defined as the time from the first documented CR or PR to the first documented disease progression or death, whichever occurs first.
- Progression-Free Survival (PFS) [Study duration of approximately 29 months]
PFS is defined as the time from first dose to the first documented disease progression per RECIST 1.1 by investigator or death, whichever occurs first.
- Anti-drug antibodies (ADAs) of IGM-7354 [At pre-defined intervals from Cycle 1 Day 1 through end of treatment at approximately 12 months (each cycle is 28 days)]
Immunogenicity of IGM-7354
