study of ixazomib with pegylated ifn-alpha 2b (pifn) in metastatic renal cell carcinoma (mrcc)

Conditions: Metastatic Renal Cell Carcinoma; RCC

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.


Eligibility criteria:
inclusion: 1. male or female patients 18 years or older. 2. voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care. 3.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. 7. patients must meet the following clinical laboratory criteria: * absolute neutrophil count (anc) ≥ 1,000/mm3 and platelet count ≥ 75,000/mm3 and hemoglobin ≥ 9 g/dl. platelet or red cell transfusions to help patients meet eligibility criteria are not allowed within 3 days before study enrollment. * total bilirubin ≤ 1.5 x the upper limit of the normal range (uln). * alanine aminotransferase (alt) and aspartate aminotransferase (ast) ≤ 3 x uln. * calculated by cockcroft-gault creatinine clearance ≥ 30 ml/min (see section 12.2). 8. measurable disease by recist 1.1. 9. receipt of at least two line of prior therapy for metastatic rcc. 10. patients with stable brain metastasis are eligible provided they received definitive therapy (ebrt, gamma knife, surgery) no sooner than 14 days prior to registration and are off all steroids. exclusion: patients meeting any of the following exclusion criteria are not to be enrolled in the study: 1. female patients who are lactating or have a positive serum pregnancy test during the screening period. 2. failure to have fully recovered (ie, ≤ grade 1 toxicity) from the reversible effects of prior chemotherapy, radiation therapy or targeted therapy 3. previous use of interferon, ixazomib or bortezomib. 4. washout periods for prior therapy are as follows * bevacizumab - last dose must be ≥ 6 weeks prior to day 1 of study treatment. * targeted therapy - last dose must be ≥ 5 half-lives prior to initiation of day 1 of study treatment. * other chemotherapy, immunotherapy, or radiotherapy - last dose must be ≤ 3 weeks prior to day 1 of study treatment 5. major surgery within 14 days before enrollment. 6. radiotherapy within 14 days before enrollment. if the involved field is small, 7 days will be considered a sufficient interval between treatment and administration of the ixazomib. 7. untreated central nervous system involvement. 8. uncontrolled thyroid disease. 9. infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment. 10. evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months. 11. systemic treatment, within 14 days before the first dose of ixazomib, with strong inhibitors of cyp1a2 (fluvoxamine, enoxacin, ciprofloxacin), strong inhibitors of cyp3a (clarithromycin, telithromycin, itraconazole, voriconazole, ketoconazole, nefazodone, posaconazole) or strong cyp3a inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of ginkgo biloba or st. john's wort. 12. known ongoing or active systemic infection, active hepatitis b or c virus infection, or known human immunodeficiency virus (hiv) positive. 13. decompensated liver disease (child-pugh score \>6) or active or past auto-immune hepatitis. 14. any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol. in particular, a history of a serous psychiatric illness that might be exacerbated by ifn-α-2b; a history of significant or unstable cardiovascular, hepatic or gastrointestinal disease; a history of autoimmune disease of any kind. 15. known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent. 16. known gi disease or gi procedure that could interfere with the oral absorption or tolerance of ixazomib including difficulty swallowing. 17. evidence of another clinically or radiographically active invasive malignancy or diagnosed or treated for another malignancy within 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease. patients with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection. 18. patient has ≥ grade 3 peripheral neuropathy, or grade 2 peripheral neuropathy with pain on clinical examination during the screening period. 19. participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial.
