A Study of Nivolumab Combined With FOLFOX and Regorafenib in People Who Have HER2-Negative Esophagogastric Cancer

• Status: Recruiting
• Trial end date: 2023-02-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to find out whether combining nivolumab, FOLFOX, and regorafenib may be a safe and effective treatment for people who have HER2-negative metastatic esophagogastric cancer.

Nivolumab is an antibody, like the proteins made by the immune system to protect the body from harm. Nivolumab blocks the protein PD-1 (programmed cell death receptor-1) that usually acts as a "brake" on the immune system. Blocking this protein is like releasing the brakes, so that the immune system can target cancer cells and destroy them.

FOLFOX is a combination of three standard chemotherapy drugs (leucovorin, 5-fluorouracil, and oxaliplatin) commonly used to treat your type of cancer. The drugs work by damaging the DNA in cancer cells, which can cause the cells to stop growing and die.

Regorafenib is a type of drug called a tyrosine kinase inhibitor (TKI). This drug targets the tyrosine kinase protein found in or on the surface of cancer cells that the cells need to survive and grow. Blocking this protein may stop cancer cells from growing, or cause them to grow more slowly or to shrink.

The study researchers think that combining nivolumab, FOLFOX, and regorafenib may be a more effective treatment for HER2-negative metastatic esophagogastric cancer than the usual chemotherapy treatment(s) alone.

• Age 18 years or older

• ECOG performance status 0 to 1

• Peripheral neuropathy grade ≤1

• Available archival tissue for correlative analysis (biopsy is required if no archival tissue is available)

• Adequate organ function as below:

• Absolute neutrophil count ≥1500/mcL

• Platelets ≥100,000/mcL

• Hemoglobin ≥9 g/dL

• Serum creatinine ≤1.5X ULN

• Serum total bilirubin ≤1.5X ULN OR Direct bilirubin ≤ULN for s ubjects with total bilirubin levels >1.5X ULN, except patients with Gilbert's disease (≤3X ULN)

• AST and ALT ≤2.5X ULN

• Albumin ≥3 mg/dL

• ALT, alanine aminotransferase; AST, aminotransferase; ULN, upper limit of normal.

Exclusion Criteria:

• Confirmed HER2-positive disease (IHC 3+ or 2+, fluorescence in situ hybridization HER2:CEP17 ratio ≥2)

• Inability to swallow oral pills

• Prior chemotherapy for metastatic disease. Patients with metastatic disease after treatment for localized esophagogastric cancer may have received prior adjuvant therapy (chemotherapy and/or chemoradiation) if >6 months have elapsed between the end of adjuvant therapy and registration

• Currently participating in a study and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment

• Underwent major surgical procedure within 4 weeks of registration

• Underwent radiation within 2 weeks of registration

• Received prior therapy with regorafenib

• Received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent

• Diagnosis of immunodeficiency or receipt of systemic steroid therapy or any other form of immunosuppressive therapy within 7 days before the first dose of trial treatment

• A known history of active Bacillus tuberculosis

• A known active central nervous system metastases and/or carcinomatous meningitis

• A known history of or any evidence of active, noninfectious pneumonitis

• An active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease, systemic lupus erythematosus, Wegener syndrome [granulomatosis with polyangiitis], myasthenia gravis, Grave's disease, rheumatoid arthritis, hypophysitis, uveitis) within the 3 years before the start of treatment. The following are exceptions to this criterion:

• Subjects with vitiligo or alopecia

• Subjects with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement or psoriasis not requiring systemic treatment

• A known history of human immunodeficiency virus (HIV 1/2 antibodies)

• Known active hepatitis B (e.g., HBsAg reactive) or hepatitis C (e.g., HCV RNA [qualitative] is detected). Patients with HBsAg reactive on entecavir may be eligible after consultation with hepatologist and study team.

• Received a live vaccine within 30 days of planned start of study therapy

• Active or clinically significant cardiac disease, including congestive heart failure-New York Heart Association class >II, active coronary artery disease, cardiac arrhythmias requiring antiarrhythmic therapy other than beta blockers or digoxin, unstable angina (anginal symptoms at rest), new-onset angina within 3 months before initiation, or myocardial infarction within 6 months before initiation

• Uncontrolled hypertension (systolic pressure >140 mm Hg or diastolic pressure >90 mm Hg on repeated measurement) despite optimal medical management

• Evidence or history of bleeding diathesis or coagulopathy

• Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial

• Pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial, starting with the prescreening or screening visit through 120 days after the last dose of trial treatment

• Unwilling to give written, informed consent, unwilling to participate, or unable to comply with the protocol for the duration of the study
