Treatment Arms

ArmTypeDescription
Arm A: Dose-escalation (Stage I), Dose Expansion (Stage II)EXPERIMENTALParticipants in Stage I will receive GDC-6036 administered orally once daily (PO QD). The dose will be increased in successive cohorts until a study-specific threshold is reached. Participants with select solid tumors will be treated with GDC-6036 PO QD in Stage II.
Arm B: GDC-6036 + Atezolizumab (Stage I and Stage II)EXPERIMENTALParticipants with non-small cell lung cancer will receive GDC-6036 in combination with atezolizumab.
Arm C: GDC-6036 + Cetuximab (Stage I and Stage II)EXPERIMENTALParticipants with colorectal cancer will receive GDC-6036 in combination with cetuximab.
Arm D: GDC-6036 + Bevacizumab (Stage I and Stage II)EXPERIMENTALParticipants with solid tumors will receive GDC-6036 in combination with bevacizumab.
Arm E: GDC-6036 + Erlotinib (Stage I and Stage II)EXPERIMENTALParticipants with non-small cell lung cancer will receive GDC-6036 in combination with erlotinib.
Arm F: GDC-6036 + GDC-1971 (Stage I and Stage II)EXPERIMENTALParticipants with solid tumors will receive GDC-6036 in combination with GDC-1971 PO in Stage I. Participants with select solid tumors will be treated with GDC-6036 in combination with GDC-1971 PO in Stage II.
Arm G: GDC-6036 + Inavolisib (Stage I and Stage II)EXPERIMENTALParticipants with solid tumors will receive GDC-6036 in combination with inavolisib PO in Stage I. Participants with select solid tumors will be treated with GDC-6036 in combination with inavolisib PO in Stage II.

Frequently asked questions about GDC-6036

What is GDC-6036 used for?

GDC-6036 is an investigational small molecule being studied for the treatment of Non-Small Cell Lung Cancer, as well as Colorectal Cancer and other Advanced Solid Tumors. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does GDC-6036 target?

GDC-6036 targets cancers with a KRAS G12C mutation. It is being evaluated in participants with advanced or metastatic solid tumors that carry this specific genetic alteration, including Non-Small Cell Lung Cancer and Colorectal Cancer.

Who makes GDC-6036?

GDC-6036 is being developed by Roche Holding AG, which trades under the ticker RHHBY. The company is conducting clinical trials to evaluate the safety, pharmacokinetics, and activity of the drug in patients with KRAS G12C-mutated tumors.

What phase is GDC-6036 in?

GDC-6036 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 1 trial is active but not recruiting participants.

What clinical trials is GDC-6036 in?

GDC-6036 is being studied in a single Phase 1 clinical trial with the identifier NCT04449874. This trial evaluates the drug alone or in combination in participants with advanced or metastatic solid tumors with a KRAS G12C mutation, enrolling approximately 498 patients across multiple countries.

Is GDC-6036 the same as other KRAS G12C inhibitors?

GDC-6036 is a distinct investigational drug targeting the KRAS G12C mutation. It is being developed by Roche and is currently in Phase 1 trials. No alternative names for GDC-6036 have been disclosed in the available clinical trial information.
