PI3K Inhibitors for the Treatment of Relapsed/Refractory Indolent T/NK-cell Lymphomas

August 11, 2025 updated by: Institute of Hematology & Blood Diseases Hospital, China

Exploratory Clinical Study of PI3K Inhibitors in the Treatment of Relapsed/Refractory Indolent T/NK-Cell Lymphomas：An Open, Prospective, Exploratory Clinical Trial

Indolent T/NK-cell lymphomas are a heterogeneous group of lymphoproliferative diseases originating from T/NK cells, characterized by slow growth and proliferation, but currently remain incurable. For indolent T/NK-cell lymphomas that are unresponsive to first-line treatment, there are few treatment options available and the prognosis is poor. This study is an open-label, prospective clinical trial aimed at evaluating the feasibility, efficacy, and safety of PI3K inhibitors in the treatment of relapsed/refractory indolent T/NK-cell lymphomas. Patients will be treated with Linperlisib or Duvelisib, with an expected overall response rate of 60% for PI3K inhibitor treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Plan to enroll 51 patients with relapsed/refractory indolent T/NK-cell lymphomas; they will receive PI3K inhibitor treatment (including Linperlisib 80mg QD orally, or Duvelisib 25mg BID orally, with a 28-day cycle. Efficacy will be evaluated once per cycle during the first year, and once every two cycles thereafter. Treatment will continue for up to 24 cycles, or until disease progression, lack of response within the first 6 cycles, or the occurrence of intolerable toxicity, whichever occurs first

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

the proportion of patients whose tumors have not progressed after treatment over a specific period of time. Specifically, DCR includes the percentage of patients who achieve complete response (CR), partial response (PR), and stable disease (SD).

Exclusion Criteria:

Here is the translated text:

  1. Subjects who have previously used any PI3K inhibitors;
  2. Clinical conditions of dysphagia, malabsorption, or other chronic gastrointestinal diseases that may interfere with compliance and/or absorption of the study drug;
  3. Unable to discontinue medications that may prolong the QT interval (such as antiarrhythmic drugs) during the study period;
  4. Active viral, bacterial, or fungal infections requiring treatment (e.g., pneumonia);
  5. HBV or HCV infection (defined as HBsAg and/or HBcAb positive with HBV DNA copy number ≥ upper limit of normal reference value) or acute or chronic active hepatitis C (HCV) antibody positive;
  6. History of immunodeficiency, including HIV positive, or other acquired or congenital immunodeficiency diseases, or history of organ transplantation, or history of allogeneic bone marrow or hematopoietic stem cell transplantation;
  7. Received autologous hematopoietic stem cell transplantation within 90 days before the first dose of study treatment;
  8. Presence of severe or uncontrolled cardiovascular disease;
  9. Presence of severe concomitant diseases that endanger patient safety or are deemed by the investigator to affect the completion of the study (e.g., uncontrolled hypertension, diabetes, thyroid disease);
  10. Pregnant or breastfeeding female patients, or baseline pregnancy test positive for women of childbearing potential;
  11. Diagnosed or treated for other malignancies within the past 5 years;
  12. Any other condition that the investigator deems unsuitable for participation in the study.
