Phase II Trial of Immunotherapy in Patients With Carcinomas Arising From the Renal Medulla

Phase II Trial of Immunotherapy in Patients With Carcinomas Arising From the Renal Medulla

To learn if the combination of nivolumab and relatlimab can help to control renal medullary carcinoma (RMC) that is locally advanced or metastatic (has spread).

OBJECTIVES

Primary objective:

To determine the objective response rate (ORR) of patients with locally advanced or metastatic RMC treated with combination nivolumab plus relatlimab. ORR is defined as the proportion of patients with a best response of complete response (CR) or partial response (PR) by the Response Evaluation Criteria. In Solid Tumors (RECIST 1.1) criteria recorded between Day 1 of the study and the date of objectively documented progression per RECIST 1.1 or the date of subsequent anti-cancer therapy, whichever occurs first. Our goal is to significantly improve the ORR compared with the historical ORR of 29% achieved in our institution using conventional cytotoxic chemotherapies.

Secondary objectives:

• To determine the efficacy and safety of the combination of nivolumab plus relatlimab in patients with RMC. Efficacy will be measured by overall survival (OS), progression-free survival (PFS), time to ORR, duration of response, and the disease control rate (DCR).
• To evaluate potential biomarkers for patient stratification and treatment response, as well as tumor antigen-specific immune responses, such as antibody and T cell responses, as surrogates for anti-tumor activity.

Inclusion Criteria:

1. Patients with locally advanced or metastatic RMC histologically confirmed by expert pathology review and loss of SMARCB1 staining by immunohistochemistry. Patients with advanced or metastatic unclassified renal cell carcinoma with medullary phenotype (a rare SMARCB1 negative RMC variant occurring in individuals without sickle hemoglobinopathies) are also eligible.

2. Patients will be eligible regardless of whether they have had prior nephrectomy or still have their primary tumor in-situ.

3. Patients must have at least one measurable site of disease, defined as a lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) and measures ≥ 15 mm with conventional techniques or ≥ 10 mm with more sensitive techniques such as MRI or CT scan. If the patient has had previous radiation to the marker lesion(s), there must be evidence of progression since the radiation.

4. Patients should be willing to provide a newly obtained fresh core biopsy of a tumor lesion. Not required if there is a recently obtained fresh specimen on an IRB approved correlated trial up to 6 weeks (42 days) prior to initiation of treatment on Day 1.

5. Patients can be either naïve for any previous systemic treatment or have had any number of prior systemic therapies. However, patients must not have received prior anticancer therapy with antiPD1, anti-PD-L1, anti-CTLA-4, or anti-LAG-3 immune checkpoint inhibitors.

6. There must be evidence of progression on or after last treatment regimen received.

7. ECOG performance status 0-2

   o NOTE: If subject is unable to walk due to paralysis, but is mobile in a wheelchair, subject is considered to be ambulatory for the purpose of assessing their performance status.

Therapeutic anticoagulation with warfarin is allowed if target INR ≤ 3 on a stable dose of warfarin or on a stable dose of low molecular weight (LMW) heparin for > 2 weeks (14 days) at the time of registration for treatment.

      12 Patients with controlled brain metastases are allowed on protocol if they had solitary brain metastases that was surgically resected or treated with radiosurgery or Gamma knife, without recurrence or edema for 1 month (4 weeks). 13 Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of the study drug. 14 Women must not be breastfeeding. 15 WOCBP must agree to follow instructions for method(s) of contraception from the time of registration for treatment for the duration of treatment with study drug (s) plus 5 half-lives of study drug (s) plus 30 days (duration of ovulatory cycle) for a total of 5 months post treatment completion. Men must agree to effective contraception from the time of registration for treatment to 7 months post last treatment with nivolumab. 16 WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements. However, WOCBP must still undergo pregnancy testing as described in these sections.

Exclusion Criteria:

1. Patients must not have any other malignancies within the past 2 years except for in situ carcinoma of any site, or adequately treated (without recurrence post-resection or post-radiotherapy) carcinoma of the cervix or basal or squamous cell carcinomas of the skin.

2. Patients currently receiving anticancer therapies or who have received anticancer therapies (including chemotherapy and targeted therapy) within 2 weeks (14 days) prior to study Day 1 are excluded. Patients who have completed palliative radiation therapy more than 14 days prior to the first dose of the combination immunotherapy are eligible.

3. Patients with persistent grade ≥2 adverse events from prior systemic therapies that would confound timely detection of immune-related adverse events or otherwise hinder patient participation in the clinical trial.

Positive test for hepatitis B virus (HBV) using HBV surface antigen (HBVsAg) test or positive test for hepatitis C virus (HCV) using HCV ribonucleic acid (RNA) or HCV antibody test indicating acute or chronic infection. If hepatitis C antibody test is positive then active infection has to be confirmed by hepatitis C RNA testing for the patient to be excluded.

9. Any underlying medical condition, which in the opinion of the Investigator, will make the administration of study drug hazardous or obscure the interpretation of adverse events, such as a condition associated with frequent diarrhea, uncontrolled nausea or vomiting. Patients with active COVID-19 disease as indicated by a positive polymerase reaction (PCR) test are excluded.

   Patients with previous COVID-19 disease are allowed if ≥30 days from last positive test, and COVID-19 symptoms have resolved and/or PCR test is now negative

If TnT or TnI repeat levels beyond 24 hours are < 2 × ULN, the participant may undergo a cardiac consultation and be considered for treatment, following cardiologist recommendation. Notification of the decision to enroll the participant following cardiologist recommendation has to be made to the MD Anderson Medical Monitor or designee.
