This is a Phase 1B study assessing the safety of immune checkpoint inhibition after SBRT in patients with recurrent or metastatic gastroesophageal cancer (limited metastatic disease).
Full description
This is a Phase 1B study assessing the safety of immune checkpoint inhibition after SBRT in patients with recurrent or metastatic gastroesophageal cancer (limited metastatic disease). Arm A explores the safety and efficacy of nivolumab alone, and Arm B explores the safety and efficacy of nivolumab plus Relatlimib. Patients with recurrent or metastatic esophagogastric cancer are eligible for this study which will enroll patients with limited disease burden and who are Programmed death-1(PD-1) therapy naïve. This will allow for us to assess if systemic ablative radiation (SBRT to multiple metastatic sites plus PD-1/ anti-LAG3) is able to enhance the effectiveness of nivolumab +/- anti-LAG3 or to overcome treatment resistance mechanisms. Patients will be treated with targeted high dose radiation (SBRT) to metastatic lesions as outlined below. One of the lesions which is considered the easiest to biopsy and not causing symptoms will not be radiated so as to obtain tissue for correlative analysis. This lesion will then be re-biopsied approx. 4 weeks after the completion of radiation to the other metastatic sites. If a lesion is causing pain or other symptoms this site will not be chosen as the biopsiable site. The chosen metastatic lesion can then be irradiated at a later date if we do not see disease response in that region. Approximately 21 patients will be enrolled on study with 6 enrolled on Arm A, and 15 enrolled on Arm B.

Inclusion criteria
Men and women aged ≥ 18 years old.
Histologically proven (squamous cell or adenocarcinoma) esophageal or gastro-esophageal junction cancer or gastric cancer (core biopsy required)
Either a formalin fixed paraffin block or a minimum of ten 5-micron tissue section's (slides) of tumor biopsy sample must be available for biomarker evaluation.
Recurrent disease or Stage IV disease as per American Joint Committee on Cancer (AJCC) staging 8.0 - patients who decline systemic chemotherapy in the first line metastatic setting are eligible.
(Relatlimab arm only) LVEF assessment with documented left ventricular ejection fraction ( LVEF) >/=50% by either echocardiogram TTE or multigated acquisition scan (MUGA) (TTE preferred test) within 6 months from first study drug administration,whichever is most recent.
Eastern Cooperative Oncology Group (ECOG) performance status 0-1
Adequate organ function as follows:
The effects of nivolumab, relatlimab or BMS-986178, on the developing human fetus are unknown. For this reason women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for 5 months after the last dose of nivolumab +/- IO therapy. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Sexually active fertile men must use effective barrier birth control if their partners are WOCBP for 7 months after the last dose of nivolumab +/- IO therapy. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within two weeks of registration.
Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception (see Appendix 4) for the duration of treatment with study treatment(s) plus 33 weeks after the last dose of the study treatment (ie, 90 days [duration of sperm turnover] plus the time required for nivolumab and relatlimab to undergo approximately 5 half-lives). In addition, male participants must be willing to refrain from sperm donation during this time.
Patient understands the study regimen, its requirements, risks and discomforts and is able and willing to sign the informed consent form. Voluntary signed and dated Institutional Review Board (IRB) approved written informed consent form in accordance with regulatory and institutional guidelines must be obtained before the performance of any protocol related procedures that are not part of normal patient care. Subjects must be competent to report Adverse Events (AEs), understand the drug dosing schedule and use of medications to control AEs.
