Regorafenib in Treating Patients With Locally Advanced Cancer of the Esophagus or Gastroesophageal Junction Who Have Completed Chemoradiation Therapy and Surgery

Phase 2

Terminated

Conditions: Stage IIIC Esophageal Adenocarcinoma
Stage IIB Esophageal Adenocarcinoma
Adenocarcinoma of the Gastroesophageal Junction
Stage IIIB Esophageal Adenocarcinoma
Stage IIIA Esophageal Adenocarcinoma

Interventions: Drug: Regorafenib
Other: Placebo

Registration Number: NCT02234180

Lead Sponsor: Academic and Community Cancer Research United

Brief Summary: This randomized phase II trial studies how well regorafenib works in treating patients with cancer of the esophagus or gastroesophageal junction that has spread from where it started to nearby tissue or lymph nodes and have completed chemoradiation therapy and surgery. Regorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description: PRIMARY OBJECTIVES:

I. To compare the disease-free survival (DFS) for patients with resected esophageal and gastroesophageal (GE) junction adenocarcinoma treated with regorafenib vs. placebo in the adjuvant setting.

SECONDARY OBJECTIVES:

I. To compare the safety profile of adjuvant regorafenib vs. placebo in patients with locally advanced resectable esophageal and GE junction adenocarcinoma.

II. To compare the overall survival (OS) for patients with resected esophageal and GE junction adenocarcinoma treated with regorafenib vs. placebo in the adjuvant setting.

III. To compare the DFS in those patients that receive at least 1 cycle of therapy.

IV. To collect tumor samples for future genomic analysis to explore the biology of locally advanced esophageal and GE junction adenocarcinoma.

V. DFS will be compared between the arms from the time of surgery as well.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Within 6-12 weeks after surgery, patients receive regorafenib orally (PO) once daily (QD) on days 1-21.

ARM II: Within 6-12 weeks after surgery, patients receive placebo PO QD on days 1-21.

In both arms, courses repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years, and every 6 months for up to 5 years.

Study & Design

Study Type: INTERVENTIONAL

Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Arm I (regorafenib)	Regorafenib	Within 6-12 weeks after surgery, patients receive regorafenib PO QD on days 1-21. Courses repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity.
Arm II (placebo)	Placebo	Within 6-12 weeks after surgery, patients receive placebo PO QD on days 1-21. Courses repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
Disease Free Survival (DFS)	Time from randomization to the first of either disease recurrence or death from any cause, assessed up to 1 year and 10 months	Disease free survival (DFS) is defined as the time from randomization to the first of either disease recurrence or death from any cause. The distribution of DFS will be estimated using the Kaplan Meier method.

Secondary Outcome Measures

Name	Time	Method
Overall Survival (OS)	Time from randomization to death due to any cause, assessed up to 1 year and 10 months	Overall survival (OS) is defined as the time from randomization to death due to any cause.
Toxicity, Assessed Using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0 (v4)	Up to 1 year and 10 months	The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns within patient groups. In addition, we will review all adverse event data that is graded as 3, 4, or 5 and classified as either "unrelated" or "unlikely to be related" to study treatment in the event of an actual relationship developing. The overall toxicity rates (percentages) for grade 3 or higher adverse events considered at least possibly related to treatment are reported below.
