Patient case: 54-year-old male with melanoma; genetic feature: BRAF (V600K)

Clinical trial: A Study of CDX-1127 (Varlilumab) in Patients With Select Solid Tumor Types or Hematologic Cancers

Summary: This is a study of CDX-1127, a therapy that targets the immune system and may act to promote anti-cancer effects. The study enrolls patients with hematologic cancers (certain leukemias and lymphomas), as well as patients with select types of solid tumors.

Detailed description: CDX-1127 is a fully human monoclonal antibody that binds to a molecule called CD27 found on certain immune cells and also on certain hematologic tumor cells and may act to promote anti-tumor effects.
  This study will evaluate the safety and activity of escalating doses of CDX-1127 in patients with B-cell and T-cell hematologic malignancies known to express CD27 and solid tumors that are more likely to be responsive to the immune system.
  Eligible patients who enroll in the dose escalation portion of the study will be assigned to one of 5 dose levels of CDX-1127. This first phase of the study will test the safety profile of CDX-1127 and will assess which dose to test in future studies.
  During the Expansion phase, cohorts of approximately 15 patients each will receive the study treatment to continue to evaluate the safety profile of CDX-1127 and to determine if it has an effect on their cancer. Expansion cohorts may be limited to one or more tumor types.
  Patients enrolled in the study may receive study treatment for up to 5 cycles, until their disease has progressed or until it is necessary to stop the treatment for safety or other reasons.
  All patients enrolled in the study will be closely monitored to determine if their cancer is responding to treatment and for any side effects that may occur.

Eligibility: Inclusion Criteria:
  Among other criteria, patients must meet the following conditions to be eligible for the study:
  1. 18 years of age or older.
  2. Body Weight ≤ 120 kg.
  3. Histologic diagnosis of either a B-cell or T-cell hematologic malignancy known to express CD27 or one of the following solid tumors: metastatic melanoma, renal (clear) cell carcinoma, hormone-refractory prostate adenocarcinoma, ovarian cancer, colorectal adenocarcinoma or non-small cell lung cancer. For the solid tumor expansion cohorts, enrollment is limited to the following solid tumors: melanoma and renal cell carcinoma.
  4. Tumor must be recurrent or treatment refractory with no remaining alternative, approved therapy options, with the following exception: melanoma patients enrolled in the expansion phase must have previously received ipilimumab and, for patients with the BRAF V600E mutation, vemurafenib, or have been offered such therapies and refused, and patients must have progressive disease subsequent to previous therapies.
  5. Measurable or evaluable disease.
  6. Have adequate blood, bone marrow, liver and kidney function as determined by laboratory tests.
  7. If of childbearing potential (male or female), agree to practice an effective form of contraception during study treatment.
  8. Have little or no side effects remaining from prior cancer therapies.
  9. Provide written informed consent.
  Exclusion Criteria:
  Among other criteria, patients who meet the following conditions are NOT eligible for the study:
  1. Known prior primary or metastatic brain or meningeal tumors.
  2. Receiving treatment with immunosuppressive agents, including any systemic steroids.
  3. Active infection requiring systemic therapy, known HIV infection, or positive test for hepatitis B surface antigen or hepatitis C.
  4. Is being treated for anti-coagulation (i.e. warfarin) for reasons other than catheter patency.
  5. Women who are pregnant or lactating.
  6. Prior allogeneic bone marrow transplant.
  7. Autologous bone marrow transplant within 100 days of first dosing.
  8. Recent chemotherapy or other anti-cancer therapy (within 2 - 14 weeks depending on treatment type).
  9. Systemic radiation therapy within 4 weeks or prior focal radiotherapy within 2 weeks prior to first dosing.
