Brief Summary
The goal of this clinical trial is to evaluate if bemarituzumab in combination with different standard of care chemotherapies enhance tumor response in patients with FGFR2b-positive advanced or metastatic adenocarcinoma of the stomach or gastroesophageal junction. The main questions are:
How do patients respond to these treatments? How is the overall and the progression-free survival rate with these treatments? How is the disease control rate with these treatments? How long is the duration of response and disease stabilization with these treatments? How is the safety with these treatments? How is the quality of life with these treatments?
Patients will be allocated to one of three possible treatment cohorts according to investigator's decision and current standard of care:
Bemarituzumab with cohort 1: irinotecan cohort 2: paclitaxel plus ramucirumab cohort 3: trifluridine/tipiracil

Outcome Measures
Primary Outcomes (1)
Objective response rate (ORR)
Objective response rate (ORR), defined as proportion of subjects with a complete response (CR) or partial response (PR) acc. to RECIST v1.1, for each cohort (cohort 1 - bemarituzumab plus irinotecan, cohort 2 - bemarituzumab plus paclitaxel and ramucirumab, cohort 3 - bemarituzumab plus trifluridine/tipiracil).
from date of enrollment to date of last response acc. to RECIST v1.1 or death due to any cause, through study completion, up to 33 months
Secondary Outcomes (8)
Progression-free survival (PFS)
from date of enrollment to date of progression acc. to RECIST v1.1 or death due to any cause, through study completion, up to 33 months
Overall survival (OS)
time from date of enrollment to date of death due to any cause, through study completion, up to 33 months
Disease control rate (DCR)
time from date of enrollment to date of last tumor assessment acc. to RECIST 1.1 or death due to any cause, through study completion, up to 33 months
Duration of response (DoR)
time from response initiation (when either CR or PR is first determined) to date of progression or death to any cause, through study completion, up to 33 months
Disease stabilization
time from the first assessment of CR or PR or SD until the date of progression or death to any cause, through study completion, up to 33 months
+3 more secondary outcomes
Study Arms (3)
Cohort 1
EXPERIMENTAL
bemarituzumab plus SOC treatment with irinotecan
Drug: bemarituzumab, irinotecan
Cohort 2
EXPERIMENTAL
bemarituzumab plus SOC treatment with paclitaxel plus ramucirumab
Drug: bemarituzumab, paclitaxel, ramucirumab
Cohort 3
EXPERIMENTAL
bemarituzumab plus SOC treatment with trifluridine/tipiracil
Patient has been diagnosed with histologically proven advanced or metastatic adenocarcinoma of the stomach or of the gastroesophageal junction, which is not amenable to potentially curative resection. Primary tumor locations will be classified following AJCC/UICC 8th ed.
Patient has measurable disease or non-measurable, but evaluable disease, according to RECIST v1.1
Patient received at least one previous line of treatment, which includes a fluoropyrimidine and a platinum, in the advanced setting or the patient has been intolerable or ineligible to fluoropyrimidine and/or platinum. Neoadjuvant/adjuvant treatment is not counted unless progression occurs \<6 months after completion of the treatment. In these cases, neoadjuvant/adjuvant treatment is counted as one line of therapy.
Note: patient allocation to cohort 3 only if patient received at least two previous lines of treatment.
Tumor material (archival and/or fresh) is available for centrally FGFR2b testing performed by IHC.
FGFR2b-selected population using 2+/3+ definition in ≥ 10% tumor cells.
Patients with HER2/neu-positive tumors are eligible if they received prior HER2/neu-targeted therapy.
Patient has an ECOG performance status ≤ 1.
Patient has a life expectancy \> 12 weeks.
Patient has adequate hematological, hepatic and renal function.
Absolute number of neutrophils (ANC) ≥ 1.5 x 109/L
Platelets ≥ 100 x 109/L
Hemoglobin ≥ 9 g/dL (5.58 mmol/L), without transfusion support within 7 days before the first dose of study treatment
+6 more criteria
You may not qualify if:
Patient received prior treatment any selective inhibitor of the FGF-FGFR pathway or participated in a study that randomized to FGFR-targeted therapy/placebo.
Patient has known allergic / hypersensitive reactions to at least one of the treatment components
Contraindication for standard of care (SOC) treatment regimen chosen by investigator (irinotecan, paclitaxel plus ramucirumab or trifluridine/tipiracil) according to specific product information or clinical standards
Patient has known presence of tumors other than adenocarcinomas (e.g., leiomyosarcoma, lymphoma) or a secondary tumor other than squamous or basal cell carcinomas of the skin or in situ carcinomas of the cervix which have been effectively treated. The sponsor decides to include patients who have received curative treatment and have been disease-free for at least 5 years.
Patient has squamous/ adenosquamous cell carcinoma of the stomach or gastroesophageal junction.
Patient receives simultaneous, ongoing, systemic immunotherapy, chemotherapy, hormone therapy or investigational treatment not described in the study protocol.
Patient receives current treatment with any anti-cancer therapy or major surgery ≤ 2 weeks prior to study treatment start unless rapidly progressing disease is measured.
Patient receives simultaneous treatment with a different anti-cancer therapy (including investigational treatments) other than that provided for in the trial (excluding palliative radiotherapy for symptom control).
Patient has known untreated or symptomatic CNS or leptomeningeal metastases. Subjects with asymptomatic CNS metastases are eligible if clinically stable for ≥ 4 weeks and require no intervention (including use of corticosteroids). Subjects with treated brain metastases are eligible provided the following criteria are met:
Definitive therapy was completed at least 2 weeks prior to the first planned dose of trial treatment (stereotactic radiosurgery at least 7 days prior to first planned dose of study treatment)
At least 7 days prior to first dose of trial treatment: any CNS disease is clinically stable, subject is off steroids for CNS disease (unless steroids are indicated for a reason unrelated to CNS disease), and subject is off or on stable doses of anti-epileptic drugs
Patient has impaired cardiac function or clinically significant cardiac disease including unstable angina within 6 months before the first dose of study treatment, acute myocardial infarction \< 6 months prior to the first dose of study treatment, New York Heart Association (NYHA) class II-IV congestive heart failure, uncontrolled hypertension (defined as an average systolic blood pressure \> 160 mmHg or diastolic \> 100 mmHg despite optimal treatment, uncontrolled cardiac arrhythmias requiring antiarrhythmic therapy other than beta blockers or digoxin, active coronary artery disease or corrected QT interval (QTc) ≥ 470
Patient has evidence of or any ongoing ophthalmological disorders.
