This Phase I study tests the safety and dosing of two oral drugs—ruxolitinib and duvelisib—in adults with relapsed or refractory T‑cell or NK‑cell lymphomas. The trial begins with a sequential, open-label dose-escalation phase (standard 3+3), then moves to dose-expansion groups, including a TFH/T‑PLL expansion cohort. Participants take both drugs by mouth twice daily while researchers monitor safety and early disease-control measures.
What it is studying. The study is testing the safety, tolerability, and optimal dose (maximum tolerated dose) of the combination of ruxolitinib and duvelisib in people with relapsed or refractory T‑cell and NK‑cell lymphomas. It will also collect early measures of disease control.
What the researchers hope to learn. Scientific goals: determine the maximum tolerated or optimal dose of the ruxolitinib + duvelisib combination; assess safety and tolerability; and estimate disease-control outcomes (combined complete response, partial response, and stable disease for 6 months, including improvement in cytopenias), with a separate estimate for the T-PLL and TFH lymphoma expansion cohorts.
What this study is about
The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.
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).

AI-written from the registry record, not the study's own wording. May contain errors or omissions. Check the registry text on this page and the original record ↗ before acting on it.
Participants take two study drugs by mouth every 12 hours (ruxolitinib fixed at 20 mg BID plus duvelisib at varying doses). Early participants join a dose‑escalation group with close safety monitoring (including an 8‑week observation for dose‑limiting toxicities); later there are dose‑expansion cohorts including specific T‑PLL and TFH cohorts. Study visits include regular clinic assessments, blood tests and other disease assessments (which may include peripheral blood or bone‑marrow testing and skin scoring where relevant), pregnancy testing as required, and instructions to use infection prophylaxis and stop or avoid certain interacting medications. Participants must follow contraception and vaccine rules and report side effects for ongoing safety monitoring.
How the study is structured. Phase I interventional treatment trial. Open-label (no masking), single experimental arm. Uses a sequential dose-escalation (standard 3+3) design to evaluate three duvelisib dose levels with a fixed ruxolitinib dose, followed by dose-expansion cohorts, including groups based on JAK/STAT activation status and a TFH/T‑PLL expansion. Both drugs are taken orally twice daily.

Terms used on this page · explanations by MedicalUpdates.ai
- relapsed or refractory
- A condition that has not responded to a treatment. 'Relapsed' means it responded and then came back; 'refractory' means it did not respond in the first place.
- dose escalation
- Groups of participants receive increasing doses of a treatment, one group after another, to find a dose that can be given safely.
- cohort
- A group of people who share a characteristic, such as a diagnosis, and are studied together. 'Prospective' means they are followed forward from enrolment; 'retrospective' means existing records are reviewed.
- relapsed
- A condition that improved with treatment and has since returned or worsened.
- enrollment
- The number of participants a study plans to include, or has included. 'Estimated' means the planned number; 'actual' means the number who joined.
- prior therapy
- Treatment a person has already had for the condition. A 'line of therapy' is one course of treatment; studies often require, or limit, the number of prior lines.
- Performance status
- A scale from 0 to 5 that describes how a person's condition affects daily activity. 0 means fully active; 1 means restricted in strenuous activity; 2 means able to self-care but unable to work; higher numbers mean more limitation.
- Absolute neutrophil count
- The number of neutrophils, a type of white blood cell that fights infection, in a blood sample. Studies often require it to be above a set level.
- × ULN
- The highest value of a blood test that a laboratory considers normal. Criteria such as '≤ 3 × ULN' mean the result must be no more than three times that value.
- creatinine clearance
- A measure of kidney function, calculated from a blood creatinine level together with age, weight and sex.
- study drug
- A treatment that is being tested and has not been approved for this use. It may be approved for a different condition. Being studied does not mean it works or is available outside the study.
- women of childbearing potential
- Studies often ask participants who could become pregnant, or could father a child, to use contraception during the study and for a period afterwards, because the effect of the treatment on a pregnancy is unknown.
- contraindicated
- A reason a particular test or treatment should not be used for a person, for example a metal implant that rules out an MRI scan.
- informed consent form
- The process of explaining a study, including its risks and what participation involves, so that a person can decide freely whether to take part. Consent is usually documented in writing, and a participant can choose to leave the study later.
- allogeneic stem cell transplant
- A procedure that replaces blood-forming cells after high-dose treatment. 'Autologous' uses the person's own cells collected beforehand; 'allogeneic' uses cells from a donor.
- washout period
- A period during which a participant stops a previous treatment before starting the study treatment, so the earlier treatment does not affect the results.
- Principal Investigator
- The doctor or scientist responsible for running the study at a site or overall.
- corticosteroids
- Steroid medicines, such as prednisone, that reduce inflammation. Studies often require a stable dose at entry or measure whether the study treatment allows the dose to be reduced.
- immunosuppressant
- A medicine that reduces the activity of the immune system. Studies of autoimmune conditions often require a stable dose, a prior failure, or a washout of such medicines.
- Inclusion Criteria
- The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
- Exclusion Criteria
- The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
