The film gives the main points. The full list below is copied from the registry; the study team makes the final decision.

  • Age18 Years to no maximum
  • SexAll
  • Healthy volunteersNo

You may be able to join if

  • Pathologically confirmed T or NK cell lymphoma at the enrolling institution. For CTCL, patients with stage IB disease or greater are eligible.
  • Relapse or refractory disease after at least 1 systemic therapy except for T-PLL, LGL, or T-cell Lymphoproliferative diseases with JAK2 fusion.
  • Untreated patients may be allowed after discussion with P.I.
  • Age ≥ 18
  • ECOG ≤ 2
  • Measurable disease defined by:
  • Lugano Classification for systemic lymphoma or
  • Atypical and or malignant lymphocytes quantifiable by flow cytometry or morphology in blood or bone marrow or
  • mSWAT > 0 or Sezary count ≥ 1000 cells/μL for CTCL
  • Previous systemic anti-cancer therapy for T-cell lymphoma must have been discontinued at least 2 weeks prior to treatment.
  • Glucocorticoids aimed at controlling lymphoma-related symptoms are allowed as long as they are tapered down to 20mg or less by the time of ruxolitiib initiation
  • Topical steroids for CTCL are permitted
  • See section 6.2 Subject Exclusion Criteria for guideline regarding adjuvant and maintenance therapy for prior malignancy
  • Patients must meet the following lab criteria:
  • ANC ≥ 1.0/mm^3 or ANC >/= 0.5/mm^3 (if patient has baseline neutropenia due to lymphoma), platelets ≥ 100 x 10^9/L or ≥ 50 x 10^9/L (if related to lymphoma), Hgb ≥ 8g/dL
  • Patients with LGL or T-PLL are not required to meet a minimum ANC or hemoglobin value for eligibility
  • Total bilirubin ≤ 1.5 x upper limit of normal (ULN) or; ≤ 3 x ULN if documented hepatic involvement with lymphoma, or ≤ 5 x ULN if history of Gilbert's ; AST and ALT ≤ 3 x ULN; ≤ 5 x ULN if due to lymphoma involvement
  • Creatinine clearance ≥ 30 mL/min; creatinine clearance of 15-29 mL/min will be allowed as long as baseline platelets are ≥ 150 x 10^9/L
  • For patients with positive hepatitis B core antibody or surface antigen, hepatitis B PCR must be negative and prophylaxis with entecavir or equivalent is required.
  • Patients with HIV are allowed provided that they are on anti-retroviral treatment with no active infections.

You cannot join if

  • Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
  • Uncontrolled concurrent illness including, but not limited to, ongoing or active infection, uncontrolled diabetes, clinically significant pneumonitis, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • ECOG performance status >2
  • Prior therapy with ruxolitinib
  • Receiving systemic 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
  • Adjuvant or maintenance therapy to reduce the risk of recurrence of other malignancy (other than T-cell lymphoma) is permissible after discussion with the MSK principal Investigator
  • Women of reproductive potential† must have a negative Serum ß human chorionic gonadotropin (ß-HCG) pregnancy test.
  • A female of reproductive potential is a sexually mature female who: has not undergone a hysterectomy or bilateral oophorectomy; or has not been naturally postmenopausal for at least 24 consecutive months (i.e. has had menses at any time in the preceding 24 consecutive months).

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

Treatments listed in the registry

  • Ruxolitinib (Drug)

The study

Treatment groups

Non Randomized · Parallel · masking: None

rel/ref PTCLtumors are known to contain mutations associ (Experimental)

Patients will receive ruxolitinib 20mg BID orally on 28 day cycles. Ruxolitinib should be taken by mouth every 12 hours approximately the same time each day (+/- 2 hours). Treatment may continue until disease progression, unacceptable toxicity, recommended termination by the treating physician, or termination of the study.

with rel/ref PTCL with functional evidence of JAK/STAT (Experimental)

Patients will receive ruxolitinib 20mg BID orally on 28 day cycles. Ruxolitinib should be taken by mouth every 12 hours approximately the same time each day (+/- 2 hours). Treatment may continue until disease progression, unacceptable toxicity, recommended termination by the treating physician, or termination of the study.

with rel/ref PTCL who do not meet criteria for cohort 1 or 2. (Experimental)

Patients will receive ruxolitinib 20mg BID orally on 28 day cycles. Ruxolitinib should be taken by mouth every 12 hours approximately the same time each day (+/- 2 hours).Treatment may continue until disease progression, unacceptable toxicity, recommended termination by the treating physician, or termination of the study.

Rare sub-type expansion cohort: T-PLL and T-LGL & any T-Cell/NK Lymphoma with JAK fusion mutations. (Experimental)

Patients will receive ruxolitinib 20mg BID orally on 28 day cycles. Treatment may continue until disease progression, unacceptable toxicity, recommended termination by the treating physician, or termination of the study.
