Outcome Measures
Primary Outcome Measures
- Module 1 Part A: To characterize the safety profile of GTAEXS617 as monotherapy [Through patient study completion, an average of 6 months]
Incidence of treatment-emergent adverse events (TEAEs), characterised by type, incidence, severity (graded by NCI CTCAE v5.0), seriousness, timing and relationship to GTAEXS617 dosing.
- Module 1 Part A: To characterize the Dose Limiting Toxicities (DLTs) of GTAEXS617 as monotherapy [Through patient study completion, an average of 6 months]
Incidence of dose limiting toxicities (DLTs) during Cycle 1 of treatment.
- Module 1 Part A: To establish the Recommended Phase 2 Dose (RP2D) of GTAEXS617 as monotherapy [Through study completion for all patients in Module 1 Part A. Estimated 18 months.]
The RP2D will not exceed the maximum tolerated dose (MTD) if established.
- Module 1 Part B: To characterize the safety profile of GTAEXS617 in combination with selected Standard of Care (SoC) regimens [Through patient study completion, an average of 6 months]
Incidence of treatment-emergent adverse events (TEAEs), characterised by type, incidence, severity (graded by NCI CTCAE v5.0), seriousness, timing and relationship to GTAEXS617 dosing.
- Module 1 Part B: To characterize the Dose Limiting Toxicities (DLTs) of GTAEXS617 in combination with selected Standard of Care (SoC) regimens [Through patient study completion, an average of 6 months]
Incidence of dose limiting toxicities (DLTs) during Cycle 1 of treatment
Secondary Outcome Measures
- Module 1 Part A: GTAEXS617 Maximum Plasma Concentration (Cmax) [Through patient study completion, an average of 6 months]
Maximum Plasma Concentration (Cmax) when GTAEXS617 administered as monotherapy
- Module 1 Part A: GTAEXS617 Time Maximum Plasma Concentration (Tmax) [Through patient study completion, an average of 6 months]
Time Maximum Plasma Concentration (Tmax) when GTAEXS617 administered as monotherapy
- Module 1 Part A: GTAEXS617 Area under Plasma Concentration Curve during 24 hour dosing interval (AUC 0-tau) [Through patient study completion, an average of 6 months]
Area under Plasma Concentration Curve during 24 hour dosing interval (AUC 0-tau) when GTAEXS617 administered as monotherapy
