A Study of MEK162 and AMG 479 in Patients With Selected Solid Tumors

Stopped early · Phase 1/Phase 2

Conditions studied: Metastatic Pancreatic Adenocarcinoma, BRAF Mutated Melanoma

In brief

This is a multi-center, open-label, phase Ib/II study. First, the aim of the phase Ib part is to estimate the MTD(s) and/or to identify the recommended phase II dose(s) (RP2D) for the combination of MEK162 and AMG 479 (ganitumab), followed by the phase II part to assess the clinical efficacy and to further assess the safety of the combination in selected patient populations. The dose escalation part of the study will be guided by a Bayesian Logistic Regression Model (BLRM). At least 18 patients are expected to be enrolled in the dose escalation part. Following MTD/ RP2D declaration, patients will be enrolled in three phase II arms to assess efficacy of the combination as well as to better understand the safety, tolerability, PK, antibody concentrations and PD of the combination at MTD/RP2D. Phase II arm 1 will consist of approximately 25 patients with KRAS-mutant colorectal adenocarcinoma. Phase II arm 2 will consist of approximately 20 patients with metastatic pancreatic adenocarcinoma. Phase II arm 3 will consist of approximately 28 patients with mutant BRAFV600 melanoma. Patients will be treated until progression of disease, unacceptable toxicity develops, or withdrawal of informed consent, whichever occurs first. All patients will be followed up - at minimum patients must complete the safety follow-up assessments 30 days after the last dose of the study treatment.

• Measurable disease as determined by RECIST v1.1. World Health Organization (WHO) Performance Status (PS) ≤ 2.
• Adequate organ function
• Negative serum pregnancy test

You may not qualify if…

• Prior therapy with MEK- or IGF-1R- inhibitor
• History or current evidence of central serous retinopathy (CSR), retinal vein occlusion (RVO) or retinal degenerative disease
• Patients with known history of severe infusion reactions to monoclonal antibodies
• Patients with primary CNS tumor or CNS tumor involvement
• History of thromboembolic event requiring full-dose anticoagulation therapy
• Clinically significant cardiac disease
• History of another malignancy within 2 years
