Brief Summary:
While chimeric antigen receptor T-cell (CAR T-cell) therapy produces impressive response rates in heavily pre-treated patients, early loss of response remains a barrier. One potential mechanism of relapse is limited CAR T-cell persistence. Pre-clinical research shows that PI3K inhibition represents an intriguing mechanism for increasing CAR T-cell persistence that is easily reversible and CAR T-cell agnostic. The investigators hypothesize that PI3K inhibition with duvelisib would be safe, may provide effective prophylaxis against cytokine release syndrome (CRS), and may enhance the persistence and efficacy of CAR T-cells in the treatment of hematologic malignancies.

Estimated Primary Completion Date : May 31, 2025
Estimated Study Completion Date : May 31, 2025


Arm Intervention/treatment
Experimental: Dose Escalation Stage: Duvelisib
  • Duvelisib is an oral medication taken on a twice daily basis on all dosing days. Doses being explored in this study are 15 mg BID (starting dose), 25 mg BID, and 15 mg QD. In the dose escalation stage, patients will receive duvelisib from Day -2 through Day 28.
  • CAR T-cells will be given per standard of care.
Drug: Duvelisib
Patients should take duvelisib at approximately the same time every day, with or without food.

Experimental: Cohort A Dose Expansion Stage: Duvelisib
  • Patients in Cohort A will receive duvelisib from Day -2 to Day 28. The dose that will be given will be determined in the dose escalation stage (the maximum tolerated dose).
  • CAR T-cells will be given per standard of care.
Drug: Duvelisib
Patients should take duvelisib at approximately the same time every day, with or without food.

Experimental: Cohort B Dose Expansion Stage: Duvelisib
  • Patients in Cohort B will receive duvelisib from Day -2 to Day 180. The dose that will be given will be one dose level below the maximum tolerated dose determined in the dose escalation stage.
  • CAR T-cells will be given per standard of care.
Drug: Duvelisib
Patients should take duvelisib at approximately the same time every day, with or without food.

  3. Number of participants who receive anti-IL-6 agents for treatment of cytokine release syndrome (CRS) [ Time Frame: Through completion of follow-up (estimated to be 6 months) ]
  4. Number of participants who receive steroids for treatment of cytokine release syndrome (CRS) [ Time Frame: Through completion of follow-up (estimated to be 6 months) ]
  5. Number of participants with complete response (CR) [ Time Frame: Through completion of follow-up (estimated to be 6 months) ]
  6. Best overall response rate [ Time Frame: At 1 month ]
    -Defined as proportion of subjects with complete response (CR) or partial response (PR) by Lugano criteria

  7. Best overall response rate [ Time Frame: At 3 months ]
    -Defined as proportion of subjects with complete response (CR) or partial response (PR)

  8. Best overall response rate [ Time Frame: At 6 months ]
    -Defined as proportion of subjects with complete response (CR) or partial response (PR)

  9. Progression-free survival (PFS) [ Time Frame: Through completion of follow-up (estimated to be 6 months) ]
  10. Overall survival (OS) [ Time Frame: Through completion of follow-up (estimated to be 6 months) ]
  11. Proportion of participants with partial response (PR) on Day 30 with improved response on Day 90 [ Time Frame: Day 90 ]
  12. Proportion of participants with partial response (PR) on Day 30 with improved response on Day 180 [ Time Frame: Day 180 ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Meets FDA-approved criteria for treatment of non-Hodgkin lymphoma (NHL) with axicabtagene ciloleucel (Yescarta), tisagenlecleucel (Kymriah), lisocabtagene maraleucel (Breyanzi) or brexucabtagene autoleucel (Tecartus). Subjects receiving breuxacabtagene autoleucel for treatment of B-cell acute lymphoblastic leukemia (ALL) are not eligible.
  • At least 18 years of age.
  • The effects of duvelisib on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation, and for at least 3 months after the last dose of duvelisib, as well as conform to institutional CAR T-cell guidelines. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of the study, and for at least 3 months after the last dose of duvelisib.
  • Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).
