Руксолитиниб для лечения Т-клеточного крупнозернистого лимфоцитарного лейкоза

30 сентября 2026 г. обновлено: Jonathan Brammer

Исследование фазы II по оценке эффективности руксолитиниба у пациентов с Т-клеточным крупнозернистым лимфоцитарным лейкозом (T-LGLL)

This phase II trial tests whether ruxolitinib works to shrink tumors in patients with T-cell large granular lymphocyte leukemia. Ruxolitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Подробное описание

PRIMARY OBJECTIVE:

I. Determine the overall response rate (ORR) of ruxolitinib in patients with T-cell large granular lymphocytic leukemia (T-LGLL) as compared to historical controls.

SECONDARY OBJECTIVES:

I. Rate of conversion from PR at 4 months to CR at 8 and 12 months (at full ruxolitinib dosage).

II. Rate of molecular remission (T-cell receptor [TCR] clearance, STAT3 mutation clearance) at 4, 8, 12 months.

III. Incidence of grade III/IV toxicities (at full ruxolitinib dosage). IV. Quality of life using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), Health Assessment Questionnaire Disability Index (HAQDi), and Short Form (SF)-36 questionnaire at baseline, 5 months, and every 6 months during response follow up for up to 12 months.

EXPLORATORY OBJECTIVE:

I. Objective benefit (OB) rate at 4 months defined as a patient that had improvement in their cytopenias, transfusion dependence but not attaining a partial response (PR).

II. Leukemia-free survival III. Progression-free survival

OUTLINE:

Patients receive ruxolitinib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days for 12 months in the absence of disease progression or unacceptable toxicity. Patients who achieve a response (CR or PR) may receive an additional 12 months of ruxolitinib, for a maximum of 24 months. Additionally, patients undergo blood sample collection throughout study.

This also includes patients with rare T-LGLL variants include CD4+ T-LGLL, and gamma/delta T-LGLL which can be CD4- and CD8-), though patients still must have the presence of a clonal T-cell receptor within 1 month of diagnosis or relapse. Note: patients with MDS-like T-LGLL may be included with PI approval even if CD3+CD8+ cell population is < 650/mm^3, though +TCR is required. Natural-Killer (NK) LGL is also permitted, provided there is a clonal NK-cell population noted with > 500 cells/mm^3

  • Untreated T-LGLL or failed at least one line of frontline therapy;

  • Patients must be off treatment for at least 14 days or 5 half-lives, whichever is longer

Note: Patients with platelets <100 x 109/L and renal impairment are not permitted to enroll to the study. Renal impairment is defined as creatinine clearance (CrCl) < 90 mL/min.

  • Serum creatinine =< 2 x the upper limit of normal (ULN)

  • - Estimated glomerular filtration rate (eGFR) => 30 mL/min using the Modification of Diet in Renal Disease (MDRD) equation (multiplying eGFR by each subjects Body Surface Area [BSA])

  • Total bilirubin =< 1.5 x ULN (patients with Gilbert's syndrome with a bilirubin > 1.5 x ULN permitted)

  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x ULN

  • Alkaline phosphatase (ALP) =< 2.5 x ULN

  • Eastern cooperative oncology group (ECOG) performance status =< 2

  • Men and women of reproductive potential must agree to follow accepted birth control methods for the duration of the study. Female subject is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study treatment until 5 half-lives have passed. Male subject agrees to use an acceptable method for contraception for the duration of the study treatment until 5 half-lives have passed.

  • Able to sign informed consent

Exclusion Criteria:

  • Absolute neutrophil count (ANC) less than 100/mm^3. Note: granulocyte colony-stimulating factor (G-CSF) may be utilized to enable patients to meet inclusion criteria, as long as the ANC remains above 100/mm^3 for 5 days after administration of last growth-factor.
  • Active infection requiring ongoing anti-microbial treatment. Patients with human immunodeficiency virus (HIV), positive hepatitis B surface antigen or hepatitis C antibody will be excluded. Patients with tuberculosis risk factors will be required to undergo quantiferon testing and/or purified protein derivative (PPD) testing with a negative result prior to entering the study.
  • Concurrent immune-suppressive therapy (prednisone or equivalent up to 20 mg permitted to treat LGLL symptoms, but must be weaned within one month of initiation of trial drug). Patients on stable, chronic prednisone =< 10 mg for rheumatologic/autoimmune conditions are exempted from this requirement. They may enroll on the study
  • Active, concurrent malignancy unless deemed related to T-LGLL by principal investigator (PI). Early stage skin cancers, prostate cancer, permitted if under no active therapy
  • For females of childbearing potential: Positive pregnancy test or lactating
  • Unstable angina or myocardial infarction within the past 2 months
  • Chronic obstructive pulmonary disease or other interstitial lung disease in active exacerbation
  • Cirrhosis
  • For any strong CYP3A4 inhibitors deemed a moderate or severe risk of interaction with ruxolitinib, a wash-out period of 14 days, or 5 half-lives, whichever is longer, is needed prior to starting ruxolitinib
  • Given the CYP3A4 inhibition potential of grapefruit, grapefruit juice, Seville orange juice, pomelos, and starfruits, patients will need to refrain from these foods/drinks for 14 days prior to initiation of therapy, and throughout the study period

Первичные показатели результатов

Мера результата
Мера Описание
Временное ограничение
Overall response rate (ORR)
Временное ограничение: Up to 12 months

The ORR will be calculated as the proportion of patients who achieve a response to therapy divided by the total number of evaluable patients. An evaluable patient is defined as an eligible patient who has received at least four months of therapy with ruxolitinib. All evaluable patients will be included in calculating the ORR for the study along with corresponding 95% binomial confidence intervals (CIs) (assuming that the number of patients who respond is binomially distributed). Additional outcomes including rates of conversion from PR at 4 months to CR at 8 and 12 months on full dose ruxolitinib, and rate of molecular remission (TCR clearance, STAT3 mutation clearance) at 4, 8, 12 months on full dose ruxolitinib will also be reported as proportions with 95% binomial CIs.

Changes in QOL will be calculated from the differences in scores between baseline and 5 months, baseline and 1 year, and 5 months and 1 year, for each patient. The proportions of patients who had improvement in QOL scores between time points will be compared between responding patients and non-responding patients, patients with and without rheumatologic disease, and between patients classified as having an objective benefit and patients who did not have an objective benefit. Mean changes in patient QOL between time points will also be reported.

Changes in QOL will be calculated from the differences in scores between baseline and 5 months, baseline and 1 year, and 5 months and 1 year, for each patient. The proportions of patients who had improvement in QOL scores between time points will be compared between responding patients and non-responding patients, patients with and without rheumatologic disease, and between patients classified as having an objective benefit and patients who did not have an objective benefit. Mean changes in patient QOL between time points will also be reported.

The proportions of patients who had improvement in QOL scores between time points will be compared between responding patients and non-responding patients, patients with and without rheumatologic disease, and between patients classified as having an objective benefit and patients who did not have an objective benefit. Mean changes in patient QOL between time points will also be reported.
