Brief Summary:
This early phase I trial investigates how well duvelisib exposure before CAR-T cell manufacturing works to enhance immune profiles of T cells in patients with diffuse large B-cell lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Duvelisib, an oral phosphoinositide 3-kinase (PI3K) inhibitor, may favorably change a patient's T cells to make them more efficient and have a longer duration for manufacturing of CAR-T cells.

Condition or disease Intervention/treatment Phase
Recurrent Diffuse Large B-Cell Lymphoma Refractory Diffuse Large B-Cell Lymphoma Drug: Duvelisib Biological: Tisagenlecleucel Early Phase 1

Detailed Description:


I. To assess the increase in CD27+/CD28+ T cells, after 2-week exposure duvelisib prior to collection of mononuclear cells for chimeric antigen receptor T-cell (CART cell) manufacturing.


I. To evaluate patient compliance with duvelisib. II. To evaluate the time required for manufacturing CAR-T using mononuclear cells from duvelisib-treated patients.

III. To describe the frequencies of CD27/28 double positive T cells and CD4/8 double negative T cells.

IV. To estimate overall response rates following CART therapy. V. To describe the rates of intensive care unit (ICU) transfer due to cytokine release syndrome (CRS) and/or neurotoxicity or CRS or neurotoxicity that requires treatment with tocilizumab and/or corticosteroids after CAR-T cell therapy.

VI. To describe the safety and tolerability profile of duvelisib throughout the entire study (during duvelisib priming for 2 weeks and after CAR-T infusion for 3 months).


Patients receive duvelisib orally (PO) twice daily (BID) for 2 weeks prior to collection of CAR-T cells in the absence of disease progression or unacceptable toxicity. Patients then receive tisagenlecleucel via infusion.

Patients are followed up 100 days after CAR-T infusion.

Primary Outcome Measures :
  1. Fold-change increase in CD27/CD28 double positive T cells [ Time Frame: From Baseline up to day 15 ]
    Will estimate fold-change increase in CD27/CD28 double positive T cells following in vivo exposure to duvelisib using multiparametric flow cytometry.

Secondary Outcome Measures :
  1. Proportion of patients that completed at least 75% of duvelisib doses [ Time Frame: Up to day 15 ]
    Descriptive statistics will be used to calculate the proportion of patients that completed at least 75% of duvelisib doses as documented by the patient pill diaries. The proportion along with an exact 95% confidence interval will be reported.

  2. Manufacturing time of CAR-T 19 cells [ Time Frame: Up to day 15 ]
    Descriptive statistics will be used to calculate the median manufacturing time from the 10 patients that completed at least 75% of duvelisib doses. The median will be reported along with the minimum and maximum manufacturing times.

  3. Change in proportion of CD27/28 double positive T cells and CD4/8 double negative T cells [ Time Frame: At baseline and at day 15 ]
    A Wilcoxon signed-rank test will evaluate the change in proportion of CD27+/CD28+ and CD4-/CD8- T cells using multiparametric flow cytometry.

  4. Overall response rate (ORR) [ Time Frame: At 3 months following CAR-T cell infusion ]
    The ORR (complete response or partial response) will be summarized along with an exact 95% confidence interval. Disease response will be based on the Response Evaluation Criteria in Solid Tumors criteria (version 1.1).

  5. Frequency of intensive care unit (ICU) transfers due to cytokine release syndrome (CRS) and/or neurotoxicity [ Time Frame: Up to day 90 post CAR-T cell infusion ]
    Descriptive statistics will be used to calculate the frequency of ICU transfers due to CRS and/or neurotoxicity. Descriptive statistics will also be used to calculate the frequency of administration of tocilizumab and/or corticosteroids use for CRS and/or neurotoxicity.

  6. Incidence of grade III-IV adverse events [ Time Frame: Up to 2 weeks after last dose of duvelisib ]
    Grade III-IV toxicities (as defined by Common Terminology Criteria for Adverse Events version 5.0) during duvelisib administration or for two weeks after the last dose of duvelisib.

  • Completion of all previous therapy (including surgery, radiotherapy, chemotherapy, immunotherapy, or investigational therapy) for the treatment of their DLBCL >= 2 weeks before the start of duvelisib. There is no limit on how many previous lines of treatment a patient may have received
  • The effects of duvelisib on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) must have a negative serum or urine pregnancy test prior to starting therapy. WOCBP and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) from enrollment into this study until at least 12 months after tisagenlecleucel infusion and until CAR-T cells are no longer present by quantitative polymerase chain reaction (qPCR) on two consecutive tests (qPCR tests will be available upon request). A woman of childbearing potential (WOCBP) is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use highly effective contraception prior to the study, for the duration of study participation, and 3 months after completion of duvelisib administration. WOCBP must have a negative pregnancy test within 24 hours of leukapheresis, lymphodepletion (if performed) and tisagenlecleucel infusion (if lymphodepletion not performed)
  • The patient must be willing to comply with fertility requirements as below:
  • Total abstinence (when this is in line with the usual practice and lifestyle of the patient). Periodic abstinence (i.e, calendar, ovulation, post-ovulation methods) and withdrawals are not acceptable forms of contraception
  • Female sterilization (have had surgical bilateral oophorectomy with or without a hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone assessment
  • Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner
  • Use of oral (estrogen and progesterone), injected or implanted hormonal methods of contraception, or placement of an intrauterine device (IUD) or intrauterine system (IUS) or other forms of contraception that comparable efficacy (failure rate < 1%). In case of oral contraception, the woman should be stable on the same pill for a minimum of 3 months prior to enrollment on the study
  • Sexually active males must use a condom during intercourse from enrollment into this study until at least 12 months after tisagenlecleucel infusion and until CAR-T cells are no longer present by qPCR on two consecutive tests (qPCR tests will be available upon request). A condom is required of all sexually active male patients to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to their partner
  • Female patients must be either postmenopausal, free from menses >= 2 years (yrs), surgically sterilized, willing to use two adequate barrier methods of contraception to prevent pregnancy or agree to abstain from heterosexual activity starting with screening and for 5 months after last treatment in all patients
  • Patients must agree not to donate blood, sperm/ova or any other organs while taking protocol therapy and for at least 12 months after stopping treatment
  • Willingness and ability of the patient to comply with scheduled visits, drug administration plan, protocol specified laboratory tests, other study procedures and study restrictions
  • Evidence of personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed on the procedures to be followed, the experimental nature of the therapy, alternative, potential risks and discomforts, potential benefits and other pertinent aspects of study participation
