  • Adequate cardiac function with left ventricular ejection fraction ≥ 50% by echocardiography (ECHO) or multiple-gated acquisition (MUGA) scan.
• Adequate recovery from toxicities related to prior treatments to at least Grade 1 by CTCAE v5.0. Exceptions include alopecia and peripheral neuropathy Grade ≤ 2. Patients with other toxicities that are stable on supportive therapy may be allowed to participate with prior approval by the Sponsor.
• Male and female patients with reproductive potential agree to use a highly effective method of contraceptive during the trial and for at least 6 months following the last dose of study interventions.

Exclusion Criteria:

• Prior chemotherapy, targeted therapies, radiotherapy, immunotherapy, or treatment with an investigational agent within 14 days of first receipt of study drug (within 6 weeks for nitrosoureas, mitomycin C and chest radiation; within 6 months prior to Cycle 1 Day 1 (C1D1) for chest radiation > 30Gy).
  • Note: palliative radiation, other than to target lesions, is permitted during the study except during the DLT assessment period. Patients receiving palliative radiation during the DLT assessment period will be replaced. Prior G12C therapy must be discontinued at least 6 days prior to Day 1 of study therapy for PK lead-in.
• Presence of other malignancy that could be mistaken for the malignancy under study during disease assessments.
• History of prior malignancy, with the exception of curatively treated malignancies or malignancies with very low potential for recurrence or progression.
• Major surgery within 4 weeks (excluding placement of vascular access), minor surgery within 2 weeks, or palliative radiotherapy within 1 week of the first dose of study therapy.
• Treatment with warfarin. Patients on warfarin for deep vein thrombosis/pulmonary embolism can be converted to low-molecular-weight heparin or direct oral anticoagulants.
• Prior chemotherapy, targeted therapies, radiotherapy, immunotherapy, or treatment with an investigational agent within 14 days of first receipt of study drug (within 6 weeks for nitrosoureas, mitomycin C and chest radiation; within 6 months prior to Cycle 1 Day 1 (C1D1) for chest radiation > 30Gy).
  • Note: palliative radiation, other than to target lesions, is permitted during the study except during the DLT assessment period. Patients receiving palliative radiation during the DLT assessment period will be replaced. Prior G12C therapy must be discontinued at least 6 days prior to Day 1 of study therapy for PK lead-in.
• Presence of other malignancy that could be mistaken for the malignancy under study during disease assessments.
• History of prior malignancy, with the exception of curatively treated malignancies or malignancies with very low potential for recurrence or progression.
• Major surgery within 4 weeks (excluding placement of vascular access), minor surgery within 2 weeks, or palliative radiotherapy within 1 week of the first dose of study therapy.
• Treatment with warfarin. Patients on warfarin for deep vein thrombosis/pulmonary embolism can be converted to low-molecular-weight heparin or direct oral anticoagulants.

• Exposure to P-glycoprotein (P-gp) inhibitors or inducers or sensitive substrates with narrow therapeutic index within 14 days prior to the first dose and during the course of therapy.
• Exposure to strong inhibitors or inducers of breast cancer resistance protein (BCRP) within 14 days prior to the first dose and during the course of therapy.

Examples of visually significant corneal disorders include corneal degeneration, active or recurrent keratitis, and other forms of serious ocular surface inflammatory conditions.
