Rituximab, Venetoclax, and Bortezomib for the Treatment of Relapsed or Refractory Diffuse Large B-Cell Lymphoma

NCT04285268

Description:

This phase II trial studies how well rituximab, venetoclax, and bortezomib work in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as rituximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Venetoclax and bortezomib may stop the growth of tumor cells by blocking some of the proteins needed for cell growth. Giving rituximab, venetoclax, and bortezomib may slow or stop the growth of cancer cells in patients with diffuse large B-cell lymphoma.

Detailed Description

      PRIMARY OBJECTIVE:

      I. To determine the overall response rate (ORR) of rituximab, venetoclax, and bortezomib in
      relapsed/refractory diffuse large B-cell lymphoma.

      SECONDARY OBJECTIVES:

      I. To describe the safety profile of rituximab, venetoclax, and bortezomib in diffuse large
      B-cell lymphoma (DLBCL).

      II. To describe the progression free survival of subjects enrolled to the study.

      III. To describe the median overall survival of subjects enrolled to the study. IV. To
      describe the complete remission (CR) rate, the partial remission (PR) rate and the duration
      of response (DoR) of rituximab, venetoclax, and bortezomib in relapsed/refractory DLBCL.

      EXPLORATORY OBJECTIVE:

      I. To describe the association of BCL2 expression status, measured by immunohistochemistry
      (IHC), with ORR, CR and PR rates.

      OUTLINE:

      Patients receive rituximab intravenously (IV) on day -1 of cycle 1, then on day 1 of cycles
      2-6. Patients also receive venetoclax orally (PO) once daily (QD) on days 1-14 and bortezomib
      IV or subcutaneously (SC) on day -1 of cycle 1, then on days 1, 8, and 15 of subsequent
      cycles. Treatment repeats every 28 days for up to 6 cycles for rituximab and up to 26 cycles
      for venetoclax and bortezomib in the absence of disease progression or unacceptable toxicity.

      After completion of study treatment, patients are followed up at 30 days.

             study entry. Lesions that have been radiated in the advanced setting cannot be
             included as sites of measurable disease unless clear tumor progression has been
             documented in these lesions since the end of radiation therapy

          -  Patients with lower blood counts due to marrow involvement by DHL will be eligible for
             the study

             venetoclax

          -  Patients with known brain metastases will be excluded from this clinical trial because

             contraception (hormonal or barrier method of birth control; abstinence) prior to study
             entry, for the duration of study participation and for 12 weeks after. Should a woman
             become pregnant or suspect she is pregnant while participating in this study, she

Maximum Eligible Age:N/A
Minimum Eligible Age:18 Years
Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Overall response rate (ORR)
Time Frame:Up to 4 years
Safety Issue:
Description:Defined as the proportion of subjects who achieve a best response of a partial response (PR) or better. The ORR (complete and partial responses) will be reported as a percentage with a 95% confidence interval. If response is missing for any patients, those patients will still be included in the denominator when reporting the response rate.

Secondary Outcome Measures

Measure:Incidence of adverse events
Time Frame:Up to 30 days post treatment
Safety Issue:
Description:Toxicity parameters will be defined by National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version (V) 5.0. Descriptive statistics will be provided for the safety data.
Measure:Progression free survival (PFS)
Time Frame:From study enrollment to disease progression or death from any cause, assessed up to 4 years
Safety Issue:
Description:The Kaplan-Meier curve will be used to estimate the corresponding PFS distribution and median PFS for patients treated on this study.
Measure:Overall survival (OS)
Time Frame:From study enrollment to the date of death from any cause, assessed up to 4 years
Safety Issue:
Description:The Kaplan-Meier curve will also be used to estimate the corresponding OS distribution and median OS for all treated patients. If a subject has not died, their survival time will be censored at the date of last contact ("last known alive date").
Measure:Complete response (CR) and partial response (PR) rates
Time Frame:Up to 4 years
Safety Issue:
Description:Defined as the proportion of subjects who achieve a best response of CR or PR respectively.
Measure:Duration of response (DoR)
Time Frame:From when measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, assessed up to 4 years
Safety Issue:
Description:The Kaplan-Meier curve will be used to estimate the corresponding DoR distribution and median DoR for patients treated on this study who achieve a CR or PR.
