Description:
This open-label, multicenter, global Phase Ib study will evaluate the safety, tolerability
and pharmacokinetics of intravenous (IV) dosing of MEHD7945A in combination with oral dosing
of cobimetinib in patients with locally advanced or metastatic solid tumors that carry a
Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) mutation and for which standard therapies
do not exist, have proven ineffective or intolerable or are considered inappropriate. The
study comprises a dose-escalation (Stage 1) and an indication-specific cohort expansion stage
(Stage 2).

Purpose
This open-label, multicenter, global Phase Ib study will evaluate the safety, tolerability
and pharmacokinetics of intravenous (IV) dosing of MEHD7945A in combination with oral dosing
of cobimetinib in patients with locally advanced or metastatic solid tumors that carry a
Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) mutation and for which standard therapies

study comprises a dose-escalation (Stage 1) and an indication-specific cohort expansion stage
(Stage 2).
Trial Arms
Name | Type | Description | Interventions |
---|
MEHD7945A + Cobimetinib - Stage 1 | Experimental | Patients will receive MEHD7945A 1100 milligrams (mg) intravenous (IV) infusion every 2 weeks (q2w) in combination with cobimetinib. Cobimetinib will be administered at a starting dose of 80 mg oral tablet q2w. Cobimetinib doses will be escalated to establish maximum tolerated dose (MTD) of MEHD7945A+cobimetinib combination for Stage 2. | |
MEHD7945A + Cobimetinib - Stage 2 (CRC) | Experimental | CRC patients will receive MEHD7945A in combination with cobimetinib until disease progression or unacceptable toxicity. The doses and schedule of the combination treatment will be according to the MTD established in Stage 1. | |
MEHD7945A + Cobimetinib - Stage 2 (NSCLC) | Experimental | NSCLC patients will receive MEHD7945A in combination with cobimetinib until disease progression or unacceptable toxicity. The doses and schedule of the combination treatment will be according to the MTD established in Stage 1. | |
Eligibility Criteria
Inclusion Criteria:
- Locally advanced or metastatic solid KRAS-mutant tumors, for which standard therapies
do not exist, have proven ineffective or intolerable or are considered inappropriate
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Evaluable disease or disease measurable per modified Response Evaluation Criteria in
Solid Tumors version 1.1 (RECIST v1.1)
- Consent to provide archival tumor tissue for biomarker testing
- Additionally, for patients who are considered for enrollment into the indication
specific expansion cohorts in Stage 2, the current cancer must be either KRAS-mutant
colorectal cancer (CRC) or KRAS-mutant non-small cell lung cancer (NSCLC)
Exclusion Criteria:
- History of prior significant toxicity from another MEK pathway inhibitor or
combination of another MEK and epidermal growth factor receptor (EGFR) inhibitor
requiring discontinuation of treatment
- Previous treatment with a combination of a MEK inhibitor with an EGFR inhibitor
(applies only to the indication specific expansion cohorts in Stage 2)
- Allergy or hypersensitivity to components of the cobimetinib formulations
- History of severe (Grade 3 or 4) allergic or hypersensitivity reaction to therapeutic
antibodies that required discontinuation of therapy
- History of interstitial lung disease (ILD)
- Known severe ulcer disease
- History of or evidence of retinal pathology on ophthalmologic examination that is
considered a risk factor for neurosensory retinal detachment, central serous
chorioetinopathy (CSCR), retinal vein occlusion (RVO), or neovascular macular
degeneration
Patients will be excluded if they currently have either of the following conditions which
have been identified as risk factors for CSCR:
- Uncontrolled glaucoma with intraocular pressure greater than (>) 21 millimeters of
mercury (mm Hg)
- Grade greater than equal to (>=) 3 hypertriglyceridemia
