a study of ruxolitinib and duvelisib in people with lymphoma

Conditions: T-cell Lymphomas; NK-Cell Lymphomas; T-cell Prolymphocytic Leukemia; T-cell Large Granular Lymphocyte Leukemia

Summary: this study will test the safety of ruxolitinib, given at one dose that does not change, and duvelisib, given at different doses, to find out what effects, if any, the study treatment has on people with relapsed or refractory nk-cell or t-cell lymphoma. this study has three parts: dose escalation (part 1), dose expansion (part 2), and tfh/t-pll cohort expansion (part 3).

(lactating women must agree not to breast feed while taking study medications). 3. prior allogeneic stem cell transplant within 6 months of starting treatment or patients with active gvhd requiring immunosuppression. a. prior allogeneic stem cell transplant may be allowed after discussion with msk pi if no gvhd or immunosuppression is present at time of enrollment... d) prior use of duvelisib or ruxolitinib if either agent was discontinued due to toxicity. e) previous systemic anti-cancer therapy for tcl within 14 days of initiating study drug a. patients who have received localized rt as part of their immediate prior therapy may be allowed to enroll with shorter washout period after discussion with the msk principal investigator. i. patients receiving treatment with single agent ruxolitinib or duvelisib may be allowed to enroll onto the study without a washout period b. systemic corticosteroids must be tapered to 20mg/day or less prednisone (or equivalent) upon start of investigational treatment. c. topical steroids for ctcl is permitted on study. f) ongoing use of immunosuppressant medications, including corticosteroids greater than 20mg of prednisone or equivalent at the time of enrollment g) history of chronic liver disease, veno-occlusive disease, or current alcohol abuse h) administration of a live vaccine within 6 weeks of first dose of study drug. i) prior surgery or gastrointestinal condition that may adversely affect drug absorption (e.g., gastric bypass surgery, gastrectomy) j) patients with hiv infection if they meet either of the below criteria: i. detectable viral load ii. undetectable viral load with cd4 count \<200 or not taking anti-retroviral medications. k) patients with chronic hepatitis b or c as defined by positive hepatitis b or c serology: * subjects with a negative hbsag and a positive hbcab require an undetectable/negative hepatitis b dna test (e.g., polymerase chain reaction \[pcr\] test) to be enrolled, and must receive hepatitis b prophylaxis until at least 6 months after completion of study drug(s). l) subjects with active cmv (defined as positive cmv pcr with clinical manifestations consistent with active cmv infection) and requiring therapy. carriers will be monitored per institutional guidelines. m) unable or unwilling to receive prophylaxis against pneumocystis, herpes simplex virus, or herpes zoster g) use of medications or consumption of foods that are strong inducers or inhibitors of cyp3a * such agents must be discontinued at least 2 weeks prior to study intervention * patients who (after enrollment) require use of a strong cyp3a4 inhibitor to treat a fungal/mold infection will require dose reductions n) receipt of treatment for tuberculosis within 2 years prior to enrollment o) receiving therapy for another primary malignancy (other than t-cell lymphoma). * patients with more than one type of lymphoma may be enrolled after discussion with the msk principal investigator. * early-stage cutaneous basal cell and squamous cell carcinomas are permissible * adjuvant or maintenance therapy to reduce the risk of recurrence of other malignancy is potentially permissible after discussion with the msk principal investigator. p) known central nervous system or meningeal involvement by tcl (in the absence of symptoms, investigation into central nervous system involvement is not required). q) unstable or severe uncontrolled medical condition (e.g., unstable cardiac function, unstable pulmonary condition) or any important medical illness that would, in the investigator's judgment, increase the risk to the patient associated with his or her participation in the study.
