About this study

Official title: Phase I Multicenter Study of Ruxolitinib and Duvelisib in Relapsed or Refractory T- or NK-Cell Lymphomas

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).

Study groups in NCT05010005
Study groupRoleWhat they receive
Ruxolitinib and DuvelisibExperimentalRuxolitinib 20mg BID plus Duvelisib 25mg, 50mg, or 75mg BID. Patients will be instructed to take duvelisib and ruxolitinib by mouth every 12 hours, the same time each day, +/- 2 hours. Duvelisib and ruxolitinib will be provided via the institutional investigational pharmacy. The researchers will utilize a dose-escalation standard 3+3 design in which we evaluate 3 doses of duvelisib (25mg BID, 50mg BID, and 75mg BID) in combination with ruxolitinib 20mg BID. A minus-1 dose level of duvelisib (15mg BID) can be used if de-escalation is needed. The cohort expansion phase will have two treatment groups JAK/STAT activation or mutation present or JAK/STAT activation or mutation absent or unknown. Upon discussion with PI, the treating physician may increase dose up to 20 mg of ruxotlinib and/or 25 mg of duvelisib when deemed clinically favorable.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment for MTD/optimal dose

    3 subjects will be enrolled and followed for eight weeks of safety assessments. If no DLT is observed after all three subjects have been observed for eight weeks, a second cohort of 3 subjects will be enrolled at the next highest dose level. Cohorts will continue to be enrolled and observed until one subject experiences a DLT or the maximum dose level is reached with 0 or 1/6 DLTs.

    Measured: 1 year

Secondary outcomes (2)
  1. Estimate the disease control rate

    combined complete response, partial response, and stable disease for 6 months with improvement in cytopenia

    Measured: 6 months

  2. Estimate the disease control rate (R+D in patients with T-PLL and TFH lymphomas)

    combined complete response and partial response , and stable disease for 6 months with improvement in cytopenia

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ruxolitinib and Duvelisib in people with T-cell Lymphomas and NK-Cell Lymphomas, run by Memorial Sloan Kettering Cancer Center at 9 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 45 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment for MTD/optimal dose (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
