Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with pathologically confirmed T or NK cell lymphoma that has relapsed or is refractory after prior treatment.

Probably not a fit

Patients with untreated T or NK cell lymphoma or those with specific types of T-cell lymphoproliferative diseases may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effects of ruxolitinib, a drug that inhibits the JAK protein, on patients with relapsed or refractory T or NK cell lymphoma. The trial aims to determine both the positive and negative impacts of the drug on tumor size and patient health. Eligible participants must have a confirmed diagnosis of T or NK cell lymphoma and have previously undergone at least one systemic therapy. The study will assess the drug's efficacy in shrinking lymphomas and improving patient outcomes.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat lymphomas.

How similar studies have gone: Other studies have shown promising results with JAK inhibitors in similar conditions, indicating potential for success in this approach.

* 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).
