Outcome Measures
Primary Outcomes (4)
Part 1: Number of Participants Who Experience a Dose Limiting Toxicity (DLT)
Day 1 to Day 28
Part 1: Number of Participants Who Experience a Treatment-emergent Adverse Event (TEAE)
Adverse events (AEs) are defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment. TEAEs are any event that occurs after the participant has received study treatment. Any clinically significant changes in vital signs, visual acuity, and clinical laboratory tests that occur after study treatment administration will be recorded as TEAEs.
Day 1 to 28 days after last dose (a maximum of 2 years)
Part 1: Number of Participants Who Experience a Treatment-related Adverse Event
Day 1 to 28 days after last dose (a maximum of 2 years)
Part 2: Objective Response (OR) Rate
OR = complete response (CR) + partial response (PR), measured by computed tomography (CT) or magnetic resonance imaging (MRI) as determined by investigator per Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
Up to approximately 2 years
Secondary Outcomes (11)
Part 1: OR Rate
Up to approximately 2 years
Parts 1 and 2: Disease Control (DC) Rate
Up to approximately 2 years
Parts 1 and 2: Duration of Response (DOR)
Up to approximately 2 years
Parts 1 and 2: Time to Response
Up to approximately 2 years
Parts 1 and 2: Progression-free Survival (PFS)
Up to approximately 2 years
- +6 more secondary outcomes
Study Arms (2)
Part 1: Monotherapy Dose Exploration
EXPERIMENTALParticipants across multiple primary epithelial solid tumors with centrally determined FGFR2b overexpression and relapsed/refractory unresectable and/or metastatic disease will receive 1 of 2 dose regimens of bemarituzumab to determine recommended Phase 2 dose.
Part 2: Monotherapy Dose Expansion
EXPERIMENTALParticipants across multiple primary epithelial solid tumors with centrally determined FGFR2b overexpression and relapsed/refractory unresectable and/or metastatic disease will receive the dose of bemarituzumab identified as the recommended Phase 2 dose during Part 1.
Interventions
Intravenous (IV) infusion.

- Age ≥ 18 years (or legal adult age within country, whichever is older) at the time that the Informed Consent Form (ICF) is signed
- Histologically or cytologically confirmed cancer of one of the following types, refractory to or relapsed after at least 1 prior standard therapeutic regimen in the advanced/metastatic setting, as specified below. If no standard of care therapies exist for the participant, or the participant cannot tolerate or refuses standard of care anticancer therapy, the participant may be allowed to participate on the study after discussion between the investigator and Amgen medical monitor. Participants who have not received all approved or standard treatments for their cancer must be informed that these alternatives to receiving bemarituzumab are available prior to consenting to participate in the trial.

- Evidence of any ongoing ophthalmologic abnormalities or symptoms that are acute (within 4 weeks) or actively progressing
- Unwillingness to avoid use of contact lenses during study treatment and for at least 100 days after the end of treatment
- Recent (within 6 months) corneal surgery or ophthalmic laser treatment or recent (within 6 months) history of, or evidence of, corneal defects, corneal ulcerations, keratitis, or keratoconus, or other known abnormalities of the cornea that may pose an increased risk of developing a corneal ulcer prior/concomitant therapy

- Shared Documents
- STUDY PROTOCOL, SAP, ICF, CSR
- 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.
- 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.
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.
