Phase II Nivolumab and Ramucirumab for Patients With Previously-Treated Mesothelioma

Published: April 27, 2018

Primary Outcome Measures

  • Response Rate [ Time Frame: 24 months ]
    Evaluate response rate [complete response (CR) + partial response (PR)] of nivolumab in
    combination with ramucirumab in subjects with previously-treated mesothelioma. Response
    assessment will be performed using modified RECIST 1.1 criteria.

Secondary Outcome Measures

  • Adverse event assessment [ Time Frame: 24 months ]
    Assess adverse effects (AE) of nivolumab in combination with ramucirumab in subjects with previously-treated mesothelioma.
  • Progression-free survival [ Time Frame: 24 weeks ]
    Measure progression-free survival (PFS) defined as time from registration until objective tumor progression or death rate at 24 weeks with the combination of the anti-Programmed Death 1 (PD-1) agent, nivolumab and the anti-vascular endothelial growth factor receptor 2 (VEGFR2) antibody, ramucirumab in subjects with previously-treated mesothelioma.
  • Overall survival [ Time Frame: 24 months ]
    Measure overall survival (OS) defined as time from registration until death from any cause at 2 years after treatment with nivolumab in combination with ramucirumab in subjects with previously-treated mesothelioma.

Absolute neutrophil count (ANC) ≥ 1.5 × 109/L
platelet count ≥ 100 × 109/L
serum creatinine ≤1.5 times the ULN, or creatinine clearance (measured via 24-hour urine collection) ≥40 mL/minute (that is, if serum creatinine is >1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed)
subject’s urinary protein is ≤1+ on dipstick or routine urinalysis (UA; if urine dipstick or routine analysis is ≥2+, a 24-hour urine collection for protein must demonstrate <1000 mg of protein in 24 hours to allow participation in this protocol)
INR < 1.5 × ULN, and a partial thromboplastin time (PTT) (PTT/aPTT) < 1.5 x ULN (unless receiving anticoagulant therapy)
Subjects on full-dose anticoagulation must be on a stable dose (minimum duration 14 days) of oral anticoagulant or low molecular weight heparin (LMWH). Patients receiving warfarin must be switched to low molecular weight heparin and have achieved stable coagulation profile prior to first dose of protocol therapy. For heparin and LMWH there should be no active bleeding (that is, no bleeding within 14 days prior to first dose of protocol therapy) or pathological condition present that carries a high risk of bleeding (for example, tumor involving major vessels or known varices).
Women of childbearing potential (WOCP) must be willing to use two methods of birth control. The two birth control methods can be either two barrier methods or a barrier method plus a hormonal method to prevent pregnancy. WOCP should begin using birth control from the screening visit, throughout the study period, and up to 161 days (about 5 months) following the last dose of study drugs.
Men who are not surgically or medically sterile must agree to use an acceptable method of contraception. Male subjects with female sexual partners who are pregnant, possibly pregnant, or who could become pregnant during the study must agree to use condoms with spermicide from the date of the first dose of study drug, throughout the study period, and through at least 217 days (about 7 months) after the last dose of study drug. Total abstinence for the same study period is an acceptable alternative.
Measurable disease, defined as at least 1 tumor that fulfills the criteria for a target lesion according to modified RECIST 1.1 criteria, and obtained by imaging within 28 days prior to study registration.
Prior intracavity cytotoxic or sclerosing agents (including bleomycin) is acceptable.
Radiation therapy must be completed > 28 days before study registration, and the measurable disease must be outside of the radiation port.
Pemetrexed-containing chemotherapy must be completed > 28 days before study registration.
Must provide written informed consent and HIPAA authorization approved by an Institutional Review Board (IRB). NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
All previous toxicity resolved to Grade 1 or less.
Exclusion Criteria
Any Grade 3-4 GI bleeding within 3 months prior to study registration.
History of deep vein thrombosis, pulmonary embolism, or any other significant thromboembolism (venous port or catheter thrombosis or superficial venous thrombosis are not considered “significant”) during the 3 months prior to study registration.
Any arterial thromboembolic events, including but not limited to myocardial infarction, transient ischemic attack, cerebrovascular accident, or unstable angina, within 6 months prior to study registration.
Cirrhosis at a level of Child-Pugh B (or worse), or cirrhosis (any degree) with a history of hepatic encephalopathy, or clinically meaningful ascites resulting from cirrhosis. Clinically meaningful ascites is defined as ascites from cirrhosis requiring diuretics or paracentesis.

Prior history of GI perforation/fistula (within 6 months of study registration) or risk factors for perforation.
Serious or nonhealing wound, ulcer, or bone fracture within 28 days prior to study registration.
Active brain metastases or carcinomatous meningitis. Subjects with neurological symptoms must undergo a head CT scan or brain MRI to exclude brain metastasis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of study drugs and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 14 days prior to study registration. This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability.
