Brief Summary:

This is a Phase I/II trial of the combination pegylated IFN-alpha 2b with ixazomib in metastatic renal cell carcinoma (mRCC). Researchers believe that by disabling the protein complex NF-kB, which controls the transfer of genetic information; using the study drug Ixazomib, they can promote necrotic cell death of RCC using interferon alpha - 2b. They hypothesize that the combination of ixazomib with IFN will lead to increased necrotic cell death in RCC tumors and consequent clinical benefit to patients.

Patients will receive ixazomib capsules and pegylated IFN alfa 2b injection in this research study. Treatments will be given weekly and 4 weeks of treatment make up one cycle.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  1. Male or female patients 18 years or older.

  3. Female patients must be:

    • Postmenopausal for at least 1 year before the screening visit, OR
    • Surgically sterile, OR
    • If they are of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, OR
    • Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [eg, calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
  4. Male patients, even if surgically sterilized (ie, status post-vasectomy), must agree to practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, or agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [eg, calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
  5. Patients must have a diagnosis of a metastatic renal cell carcinoma with a ≥50% clear cell component.
  6. Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2.
