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

Summary

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.

Eligibility

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.
