Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Dose Exploration Phase
Participants will receive AMG 650 in 1 of 3 alternative schedules. The maximum tolerated dose (MTD) of each schedule will be estimated using isotonic regression (Ji et al, 2010). The Recommended Phase 2 Dose (RP2D) may be identified based on emerging safety, efficacy, and pharmacodynamics (PD) data prior to reaching an MTD.
Drug: AMG 650
AMG 650 administered orally as a tablet.
Experimental: Dose Expansion Phase Group 1: TNBC
Participants with locally advanced or metastatic triple negative breast cancer (TNBC), will be administered with the preliminary RP2D identified from the dose exploration part of the study.
Drug: AMG 650
AMG 650 administered orally as a tablet.
Experimental: Dose Expansion Phase Group 2: HGSOC
Participants with locally advanced or metastatic high grade serous ovarian cancer (HGSOC), will be administered with the preliminary RP2D identified from the dose exploration part of the study.
Drug: AMG 650
AMG 650 administered orally as a tablet.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

UNDECIDED

IPD Plan Description

De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.

IPD Sharing Time Frame

Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

IPD Sharing 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. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications. Further details are available at the URL below.
