Phase 1
Recruiting
Conditions
Advanced Solid Tumor
Interventions
Registration Number
NCT06685068
Lead Sponsor
Genmab
Brief Summary

The purpose of this trial is to evaluate the safety, tolerability, pharmacokinetics (PK), anti-tumor activity and immunogenic potential of GEN1286 in participants with advanced solid tumors.

This trial consists of 2 parts:

* Part A: Dose escalation and dose level expansion

* Part B: Tumor-specific expansion with dose optimization

Primary Outcome Measures
NameTimeMethod
Number of Participants With Adverse Events (AEs)From first dose until 12 months post last dose of study drug or withdrawal of consent, death, or study closure, whichever occurs first (Up to approximately 3 years 9 months)
Number of Participants With Dose Limiting Toxicities (DLTs)During first cycle (Cycle length=21 days)

Toxicities will be graded for severity according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria version 5.0.

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)Up to approximately 3 years 9 months

ORR is defined as the percentage of participants achieving a partial response (PR) or complete response (CR) as assessed by the investigator based on response evaluation criteria in solid tumors (RECIST) version 1.1.

Disease Control Rate (DCR)Up to approximately 3 years 9 months

DCR is defined as the percentage of participants with stable disease (SD) or achieving a PR or CR based on RECIST version 1.1 as assessed by the investigator.

Progression Free Survival (PFS)Up to approximately 3 years 9 months

PFS is defined as the time from the start of any treatment to the date of the first documented progression or death due to any cause, whichever occurs first based on RECIST version 1.1 as assessed by the investigator.

Duration of Objective Response (DOR)Up to approximately 3 years 9 months

DOR is defined as the time from the first documentation of an objective tumor response (CR or PR) to the first documentation of tumor progression or to death due to any cause, whichever comes first based on RECIST version 1.1 as assessed by the investigator.

Area Under the Plasma or Serum Concentration Time Curve (AUC) of GEN1286 Related Analytes- Antibody-Conjugated Exatecan, Total Antibody (Tab) and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Maximum Observed Plasma or Serum Concentration (Cmax) of GEN1286 Related Analytes- Antibody-Conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Time to Reach Cmax (Tmax) of GEN1286 Related Analytes- Antibody-Conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Apparent Terminal Half-life (t1/2) of GEN1286 Related Analytes- Antibody-Conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Clearance (CL) of GEN1286 Related Analytes- Antibody-conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Volume of Distribution (Vz) of GEN1286 Related Analytes- Antibody-conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
Trough Concentrations (Ctrough) of GEN1286 Related Analytes- Antibody-conjugated Exatecan, Tab and u-ExatecanPredose and postdose at multiple timepoints at end of each cycle, up to approximately 2 years 9 months (Cycle length=21 days)
