Futibatinib With Paclitaxel and Ramucirumab for the Treatment of Locally Advanced or Unresectable Gastric, Gastroesophageal Junction, or Esophageal Adenocarcinoma

May 13, 2026 updated by: Northwestern University

A Phase I/Ib Dose Escalation Trial of Futibatinib in Combination With Paclitaxel/Ramucirumab in Second Line Confirmed Locally Advanced/Unresectable Gastric, Gastroesophageal Junction, or Esophageal Adenocarcinoma

This phase I trial tests the safety, side effects and best dose of futibatinib with paclitaxel and ramucirumab for the treatment of patients with gastric, gastroesophageal junction or esophageal adenocarcinoma that has spread to nearby tissue or lymph nodes (locally advanced) or that cannot be removed by surgery (unresectable). Futibatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Ramucirumab is a monoclonal antibody that may prevent the growth of new blood vessels that tumors need to grow. Giving futibatinib with paclitaxel and ramucirumab may be safe and tolerable in treating patients with locally advanced or unresectable gastric, gastroesophageal junction or esophageal adenocarcinoma.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the safety, tolerability and maximum tolerated dose (MTD) for futibatinib in combination with paclitaxel/ramucirumab in patients with confirmed locally advanced/unresectable gastric, gastroesophageal junction, or esophageal adenocarcinoma.

SECONDARY OBJECTIVES:

I. To determine the toxicity profile of futibatinib in combination with paclitaxel/ramucirumab in patients with confirmed locally advanced/unresectable gastric, gastroesophageal junction, or esophageal adenocarcinoma using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTACE) version (v) 6.

II. To evaluate the preliminary activity (overall response rate [ORR], duration of response [DoR], progression free survival [PFS], overall survival [OS]) of futibatinib in combination with paclitaxel/ramucirumab in patients with confirmed locally advanced/unresectable gastric, gastroesophageal junction, or esophageal adenocarcinoma.

EXPANSION PHASE OBJECTIVE:

I. To evaluate the activity (ORR and DoR) of futibatinib in combination with paclitaxel/ramucirumab in patients with confirmed locally advanced/unresectable gastric, gastroesophageal junction, or esophageal adenocarcinoma.

OUTLINE: This is a dose-escalation study of futibatinib in combination with fixed-dose paclitaxel and ramucirumab followed by a dose-expansion study.

Patients receive ramucirumab intravenously (IV) over 30-60 minutes on days 1 and 15 of each cycle, paclitaxel IV over 60 minutes on days 1, 8 and 15 of each cycle, and futibatinib orally (PO) once daily (QD) on days 8-28 of cycle 1 and days 1-28 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) or magnetic resonance imaging (MRI), and optional blood and urine sample collection throughout the study.

After completion of study treatment, patients are followed up every 3 months for 2 years.

Response is defined as confirmed complete response or confirmed partial response per RECIST 1.1; and disease progression is defined as progressive disease per RECIST 1.1. Will be summarized using the Kaplan-Meier method, with estimates of median DOR and corresponding 95% confidence intervals.
