Dose escalation of D-1553 monotherapyEXPERIMENTALPhase 1a will evaluate up to 7 sequential cohorts with different doses of D-1553 to determine safety, tolerability, MTD and RDE in patients with solid tumors with KRasG12C mutation.
Dose combination of D-1553 with other therapiesEXPERIMENTALPhase 1b will determine the MTD of D-1553 in combination treatment in subjects with advanced or metastatic NSCLC, CRC and other solid tumors. There are multiple groups in Phase 1b for different tumor types and treatment combinations to evaluate safety, MTD and RP2D.
Phase 2 of D-1553 monotherapy and combination therapiesEXPERIMENTALThe Phase 2 portion is a multi-arm, parallel, open label study to evaluate the efficacy of D- 1553 single agent and combination treatments in subjects with advanced or metastatic solid tumors with KRas G12C mutation. Enrollment into phase 2 will be opened after confirmation of the recommended phase 2 dose.
