Study of Entinostat With Nivolumab Plus Ipilimumab in Previously Treated Renal Cell Carcinoma

Stopped early · Phase 2

Conditions studied: Renal Cell Carcinoma

In brief

This is a Phase II, open-label, safety, pharmacodynamic and efficacy study of entinostat in combination with nivolumab and ipilimumab in subjects with metastatic renal cell carcinoma (RCC) who have progressed on ipilimumab + nivolumab regimen. Prior to Phase II, a safety lead-in will be conducted to establish the RP2D of entinostat when used in combination with ipilimumab + nivolumab. Subjects will initially be treated with the combination of oral entinostat and intravenous (IV) nivolumab plus ipilimumab. Entinostat will be dosed weekly, and nivolumab and ipilimumab will be dosed every 3 weeks, for a total of four, 3-week cycles. Following these first four cycles, entinostat will continue to be administered weekly in combination with nivolumab every 4 weeks or every 2 weeks based on subject tolerance (ipilimumab will be discontinued), with treatment continued until disease progression or prohibitive toxicity. Anti-tumor activity will be assessed by radiological tumor assessments conducted at baseline and every 6 weeks thereafter using RECIST version 1.1.

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.

• Progressive disease (PD) on nivolumab + ipilimumab regimen. Note: Patients who have completed at least one dose of ipilimumab + nivolumab and progress or have completed the 4 doses of ipilimumab + nivolumab and progress during nivolumab monotherapy maintenance are eligible unless they have received additional treatment(s) for their renal cell carcinoma prior to registration. Patients who discontinue prior ipilimumab + nivolumab or nivolumab monotherapy for toxicity are excluded. Patients who receive nivolumab or other anti-PD-1/PD-L1 agents as subsequent therapy after ipilimumab + nivolumab are excluded.
• Target lesions according to RECIST v1.1 or non-target bone lesions assessed by bone scan or positron emission tomography (PET) scan.
• A subject with prior brain metastasis may be considered if they have completed their treatment for brain metastasis at least 4 weeks prior to study registration, have been off corticosteroids for ≥ 4 weeks, and are asymptomatic.
• Prior cancer treatment (excluding nivo/ipi) must be completed at least 28 days prior to registration and the subject must have recovered from all reversible acute toxic effects of the regimen (other than alopecia or neuropathy) to ≤Grade 1 or baseline. If subject underwent major surgery or radiation therapy of >30 Gy, they must have recovered from the toxicity and/or complications from the intervention.
• Demonstrate adequate organ function as defined in the table below; all screening labs to be obtained within 28 days prior to registration
• Platelets ≥100 x 10\^9/L
• Absolute Neutrophil Count (ANC) ≥1.5 x 10\^9/L
• Hemoglobin (Hgb) ≥9 g/dL or ≥5.6 mmol/L
• Creatinine OR Measured or calculated creatinine clearance (CrCl) (glomerular filtration rate [GFR] can also be used in place of CrCl) Creatinine clearance should be calculated per institutional standard ≤1.5 x the upper limit of normal (ULN) OR ≥60 mL/min for subject with creatinine levels >1.5 x institutional ULN
• Bilirubin ≤1.5 x ULN OR Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 x ULN
• Aspartate aminotransferase (AST) ≤3 x ULN
• Alanine aminotransferase (ALT) ≤3 x ULN
• International Normalized Ratio (INR) or Prothrombin Time (PT) Activated Partial Thromboplastin Time (aPTT) ≤ 1.5 × ULN unless subject is receiving anticoagulant therapy as long as PT/INR/PTT is within therapeutic range of intended use of anticoagulants
• Women of childbearing potential (WOCBP) must have a negative serum pregnancy test during screening and a negative urine pregnancy test within 3 days prior to first dose of study drug. If the screening serum test is done within 3 days prior to receiving the first dose of study drug, a urine test is not required.
• Women of childbearing potential must be willing to abstain from heterosexual intercourse or to use an effective method of contraception from the time of informed consent until 5 months after the last dose of study drug.
• Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving study drugs and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 3 months after the last dose of entinostat.
• As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.
• Life expectancy of at least 6 months per investigator discretion.

You may not qualify if…

• Subjects meeting any of the criteria below may not participate in the study:
• History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator, including, but not limited to:
• Myocardial infarction or arterial thromboembolic events within 6 months prior to screening or severe or unstable angina, New York Heart Association (NYHA) Class III or IV disease, or a corrected QT interval (QTc) interval > 470 msec.
• Uncontrolled hypertension or diabetes mellitus.
• Another known malignancy that is progressing or requires active treatment.
• Any prior history of other cancer within the prior 5 years with the exception of adequately treated basal cell carcinoma or cervical intraepithelial neoplasia [CIN]/cervical carcinoma in situ or melanoma in situ).

• Evidence of active autoimmune disease requiring systemic treatment within the past 90 days or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded from the study.

Subjects with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as the presence of hepatitis B core antibody [HBc Ab] and absence of HBsAg) are eligible. HBV DNA test must be performed in these subjects prior to study treatment, and results must be negative to be eligible. Subjects with a history of hepatitis C must be tested for presence of hepatitis C virus (HCV) antibody. If HCV antibody positive, subjects will only be eligible if polymerase chain reaction is negative for HCV RNA.
