A Phase 1b/2a Study Evaluating AMG 232 in Metastatic Melanoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02110355
Recruitment Status : Completed
First Posted : April 10, 2014

Brief Summary:
Phase 1b/2a, open-label, sequential dose escalation and expansion study of AMG 232 in combination with trametinib and dabrafenib in subjects with metastatic melanoma followed by a direct comparison of AMG 232 combined with trametinib and dabrafenib versus trametinib combined with dabrafenib alone.

Condition or disease Intervention/treatment Phase
Advanced Malignancy Advanced Solid Tumors Cancer Oncology Oncology Patients Tumors Melanoma Drug: AMG 232 Drug: Trametinib Drug: Dabrafenib Phase 1

Detailed Description:

The study will be conducted in 3 parts: Part 1 - Dose Escalation, Part 2 - Dose Expansion and Part 3, a randomized Phase 2a.

In both part 1 and 2, subjects will be enrolled open-label into 1 of 2 arms. For both Arm 1 and Arm 2, the part 1 dose escalation is aimed at determining an AMG 232 maximum tolerated dose (MTD) with a fixed dose of the combination drug(s) and evaluating safety, tolerability, pharmacokinetics and pharmacodynamics of each combination. Part 2 dose expansion will enroll subjects to receive therapy with a dose and schedule of AMG 232 selected from the corresponding part 1 dose escalation. In part 2 subjects will be enrolled to confirm safety and tolerability and to assess clinical activity prior to proceeding to Part 3, Phase 2a. In Phase 2a, Subjects will be randomized open-label in a 1:1 ratio to receive AMG 232 in combination with trametinib plus dabrafenib versus trametinib plus dabrafenib alone.

Only Part 1 of the study was enrolled and the study did not proceed into Phase 2.
