Nivolumab With Chemotherapy in Refractory MDS

Registration Number
NCT03259516
Lead Sponsor
St. Petersburg State Pavlov Medical University
Brief Summary

There is evidence of involvement of checkpoint pathways, including PD-1, in the pathogenesis and resistance of myelodysplastic syndrome (MDS). However monotherapy with checkpoint inhibitors was ineffective in a number of studies, indicating the presence of several mechanisms of resistance. This pilot study evaluates the safety and preliminary efficacy of nivolumab combination with currently existing treatments in MDS patients who failed at least one line of therapy. The study evaluates if there is a combination which induces objective responses.

Patients with higher risk MDS (int-2 or high by IPSS) should have failed prior at least one therapy with a hypomethylating agent or Ara-C.
  • Age 18 years or older.
  • No severe organ dysfunction: creatinine <=2.5 x ULN; serum bilirubin <=2.5 x ULN; AST and ALT <=5 x ULN.
  • Karnofsky index >=70%
  • Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotrophin (beta-hCG) pregnancy test result within 24 hours prior to the first dose of treatment and must agree to use an effective contraception to avoid pregnancy for 24 weeks
  • Males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 24 weeks after the last dose of nivolumab.
Exclusion Criteria
  • Another malignancy requiring treatment at the time of inclusion
  • History of interstitial lung disease or pneumonitis
  • Patients with any other known concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes; cardiovascular disease including congestive heart failure NYHA Class III or IV, myocardial infarction within 6 months, and poorly controlled hypertension; chronic renal failure; or active uncontrolled infection) which, in the opinion of the investigator could compromise participation in the study
  • Active, known or suspected autoimmune disease requiring treatment at the time of inclusion
