Official Title  ICMJE Phase Ib and Phase II Studies of Anti-PD-1 Antibody MK-3475 in Combination With Bevacizumab for the Treatment of Metastatic Renal Cell Carcinoma: Big Ten Cancer Research Consortium GU14-003
Brief Summary This is an open label, multi-institutional, single arm study of dose escalation phase Ib cohort, followed by a phase II cohort of anti-PD-1 antibody MK-3475 in combination with bevacizumab. No randomization or blinding is involved.
Detailed Description

OUTLINE: This is a multi-center study.

The phase Ib dose escalation study will evaluate MK-3475 in combination with bevacizumab in subjects with metastatic clear cell renal carcinoma after failure of at least one systemic therapy for metastatic disease. The phase II trial will determine the activity of the combination of MK-3475 and bevacizumab in first line therapy for subjects with metastatic clear cell renal carcinoma.

PHASE Ib DOSE ESCALATION INVESTIGATIONAL TREATMENT:

Cohort 1 will consist of 3-6 patients who will receive MK-3475 200mg and bevacizumab 5mg on day 1 of the 21-day cycle. The drugs are administered 15-30 minutes apart in separate intravenous infusions.

Cohort 2 will consist of 3-9 patients who will receive MK-3475 200mg and bevacizumab 10mg on day 1 of the 21-day cycle. The drugs are administered 15-30 minutes apart in separate intravenous infusions.

If none of the 3 subjects experience a dose limiting toxicity (DLT) during the first cycle of therapy, an additional 3 subjects will be enrolled at dose level 2. If all three subjects in dose level 2 complete the first cycle of therapy without DLT, 3 more subjects will be enrolled to ensure only 0-1 of 6 subjects have a DLT. There will be no further escalation beyond dose level 2.

PHASE II INVESTIGATIONAL TREATMENT:

The maximum safe dose of MK-3475 in combination bevacizumab (as determined in the phase 1b cohort) will be given on day 1 of each 21 day cycle. Treatment will continue until disease progression, unacceptable toxicity, subject refusal, or subject death either from progression of disease, the therapy itself, or from other causes. Subjects who voluntarily stop the study, have progressive disease, or unacceptable toxicities will be followed for a total of 24 months.

Karnofsky Performance Status (KPS) ≥ 70% within 28 days prior to registration for protocol therapy.

Life Expectancy: 6 months or greater

The following baseline labs must be completed within 28 days prior to registration for protocol therapy:

Hematopoietic:

  • Absolute neutrophil count (ANC) ≥ 1.5 × 10 9/L
  • Platelets ≥ 100 × 10 9/L
  • Hemoglobin (Hgb) ≥ 9.0 g/dL

Renal:

  • Serum creatinine ≤ 1.5 × upper limit of normal (ULN)
  • OR, if serum creatinine > 1.5 × ULN, estimated glomerular filtration rate (eGFR) ≥ 40 mL/min

Hepatic:

  • Total serum bilirubin ≤ 1.5 × ULN
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN
  • OR, AST and ALT ≤ 5 × ULN if liver function abnormalities are due to underlying malignancy

Coagulation:

  • INR < 1.5 × ULN
  • OR for subjects receiving warfarin or LMWH, the subjects must, in the investigator's opinion, be clinically stable with no evidence of active bleeding while receiving anticoagulant therapy. The INR for these subjects may exceed 1.5 × ULN if that is the goal of anticoagulant therapy.

  • Known active central nervous system (CNS) metastases and/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 trial treatment 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 7 days prior to study registration. This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability.

NOTE: Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.

  • Received prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study registration or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events from previously administered agents. NOTE: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and can still be considered for the study.
  • Any clinically significant infection defined as any acute viral, bacterial, or fungal infection that requires specific treatment. NOTE: Anti-infective treatment must be completed ≥ 7 days prior to study registration.
  • Evidence of interstitial lung disease, history of (non-infectious) pneumonitis that required steroids, or current pneumonitis.
  • Known history of active tuberculosis.
  • Any other severe, uncontrolled medical condition, including uncontrolled diabetes mellitus or unstable congestive heart failure.
  • Known allergy to pembrolizumab or any of its excipients.
  • Known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies.
  • Any condition that, in the opinion of the treating physician, would exclude the subject from receiving bevacizumab. Examples may include but are not limited to:

    • Hemoptysis (defined as > ½ teaspoon of blood)
    • Pre-existing bleeding diathesis, coagulopathy or hemorrhage
    • Myocardial infarction or cerebrovascular accident within 6 months prior to study registration
    • Any drugs or supplements that interfere with blood clotting can raise the risk of bleeding during treatment with bevacizumab. These drugs include vitamin E, non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve, Naprosyn), warfarin (Coumadin), ticlopidine (Ticlid), and clopidogrel (Plavix).These agents should be used with caution.
  • Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for enrollment in this study.
  • Presence of any non-healing wound, fracture, or ulcer within 28 days prior to study registration.
  • Any condition that, in the opinion of the investigator, might jeopardize the safety of the subject or interfere with protocol compliance.
  • Any mental or medical condition that prevents the subject from giving informed consent or participating in the trial.
  • No prior malignancy is allowed except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, Gleason ≤ grade 7 prostate cancers, or other cancer for which the subject has been disease-free for at least 5 years.
  • Received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways).
  • Treatment with any investigational agent within 28 days prior to registration for protocol therapy and the subject must have recovered from the acute toxic effects of the regimen.
