NCT06680622 | NOT YET RECRUITING | Metastatic Gastro-esophageal Adenocarcinoma

Bemarituzumab in FGFR2b+ Patients With Advanced or Metastatic Adenocarcinoma of the Stomach or Gastroesophageal Junction, Who Failed at Least One Prior Line of Palliative Chemotherapy
Sponsor:

Institute for Clinical Cancer Research IKF GmbH at Hospital Northwest

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

  • 6. Serum creatinine ≤ 1.5 x ULN or creatinine clearance (measured by 24 h urine) ≥ 50 mL/min (i.e., if serum creatinine level is \> 1.5 x ULN, then a 24- hour urine test must be performed to check the creatinine clearance to be determined).

Female patients of childbearing potential, as defined in Section 5.1.7, or male patients with female partners of childbearing potential must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of \<1% (see Section 5.1.7) per year during the treatment period and for at least 6 months after the last trial treatment. Male patients must agree not to donate sperm within the same period. Male patients with a pregnant partner must agree to remain abstinent or to use a condom for the duration of the pregnancy. Female patients of child-bearing potential must have a negative pregnancy test within the last 7 days prior to the start of trial therapy.
