Arm Intervention/treatment
Experimental: Phase 1: Dose Exploration
The recommended phase 2 target dose (RP2D) of AMG 757 in combination with AMG 404 will be estimated using a modified toxicity probability interval (mTPI-2) design. A combination RP2D may be identified based on emerging safety, efficacy, and pharmacodynamic data prior to reaching an maximum tolerated dose (MTD).
Drug: AMG 757
AMG 757 will be administered as an intravenous (IV) infusion.

Drug: AMG 404
AMG 404 will be administered as an intravenous (IV) infusion.

Experimental: Phase 2: Dose Expansion
Participants will receive the RP2D of AMG 757 in combination with AMG 404 identified in Phase 1 (dose exploration) of the study.
Drug: AMG 757
AMG 757 will be administered as an intravenous (IV) infusion.

Drug: AMG 404
AMG 404 will be administered as an intravenous (IV) infusion.

  2. Duration of Response (DOR) [ Time Frame: 12 months ]
  3. Disease Control Rate (DCR) [ Time Frame: 12 months ]
  4. Progression-free Survival (PFS) [ Time Frame: 12 months ]
  5. Overall Survival (OS) [ Time Frame: 12 months ]
  6. Maximum Observed Concentration (Cmax) of AMG 757 in Combination with AMG 404 [ Time Frame: 12 months ]
  7. Minimum Observed Concentration (Cmin) of AMG 757 in Combination with AMG 404 [ Time Frame: 12 months ]
  8. Area Under the Concentration-time Curve (AUC) Over the Dosing Interval of AMG 757 in Combination with AMG 404 [ Time Frame: 12 months ]

Access Criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement.
