Conditions
Summary
This is a prospective, multicenter, single-arm, phase 2 study. This study aims to evaluate the efficacy and safety of Linperlisib, the PI3K delta inhibitor for patients with relapsed/refractory large granular T lymphocytic leukemia.
Eligibility
Inclusion Criteria7

Neutrophil count \<0.5×10\^9/L or neutrophil count decreased with recurrent infection 3. Progressive splenomegaly and/or Massive Splenomegaly 4. Combined with autoimmune diseases requiring treatment, such as rheumatoid arthritis, autoimmune thyroiditis, etc. 5. Severe B symptoms
- Failure or intolerance to a first-line therapy
- ECOG performance status ≤2
- Expected survival ≥ 6 months
- Willing and able to comply with the requirements for this study and written informed consent

- Renal impairment: creatinine clearance \<30ml/min
- History of mental illness
- History of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, severe impairment of lung function, etc.
- Received attenuated vaccine 4 in weeks before enrollment
- Participation in another clinical trial within 4 weeks before the start of this trial
- Have an allergy to Linperlisib or any other part of this medicine.
- Pregnant or breast-feeding patients
- Patients considered to be ineligible for the study by the investigator for reasons other than the above
Interventions
Elevated PI3K activity in T-LGL likely plays an important role in the ability of the pathologic cells to avoid homeostatic apoptosis, since inhibition of this pathway leads to apoptosis in the population of cells harboring the pathologic clone. More importantly, the activity of this pathway may represent a kind of "Achilles heel" for T-LGL in that PI3K inhibitors alone are quite effective at inducing spontaneous apoptosis in the clonal CTLs after a short incubation.
