A Phase I/II Open-label, Multi-center Study of the Safety and Efficacy of IMCgp100 Using the Intra-patient Escalation Dosing Regimen in Patients With Advanced Uveal Melanoma
IMCgp100-102 is a Phase I/II study of the weekly intra-patient escalation dose regimen with IMCgp100 as a single agent in participants with metastatic uveal melanoma (mUM). According to this regimen, all participants in the trial received 2 weekly doses of IMCgp100 at a dose level below the identified weekly recommended Phase II dose (RP2D-QW) and then a dose escalation commenced at the third weekly dose at C1D15. The Phase I testing of the intra-patient escalation dosing regimen is designed to achieve a higher exposure and maximal plasma concentration of IMCgp100 after doses at Cycle 1 Day 15 (C1D15) and thereafter.
This is a Phase I/II study of IMCgp100 administered on a weekly basis with an intra-patient escalation dosing regimen. The intra-patient escalation occurred at the third weekly dose on Cycle 1 Day 15 (C1D15). According to this regimen, all participants in the trial received 2 weekly doses of IMCgp100 at a dose level below the identified weekly recommended Phase II dose (RP2D-QW), and then a dose escalation commenced at the third weekly dose at C1D15 with the goal to achieve a long-term dosing regimen at a dose higher than that identified for the weekly dosing regimen (RP2D-QW). The dose escalation identified the intra-patient escalation regimen (RP2D-IE).
The Phase I portion of the study was a standard 3+3 dose escalation design.The recommended Phase II dose of the intra-patient escalation dose regimen (RP2D-IE) was identified and expansion cohorts in metastatic uveal melanoma was accrued based on prior therapy.
