Reduce Intensity Conditioning Donor Stem Cell Transplant for the Treatment of Relapsed Multiple Myeloma

NCT04205240

Description:

This phase II trial studies how well a reduced intensity conditioning regimen after donor stem cell transplant works in treating patients with multiple myeloma that has come back (relapsed). Drugs used in chemotherapy, such as cyclophosphamide, tacrolimus, and mycophenolate mofetil, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving a reduce intensity conditioning regimen consisting of cyclophosphamide, tacrolimus, mycophenolate mofetil, and daratumumab after donor stem cell transplant may improve survival and reduce the risk of multiple myeloma coming back.

Purpose

This phase II trial studies how well a reduced intensity conditioning regimen after donor stem cell transplant works in treating patients with multiple myeloma that has come back (relapsed).

Detailed Description

      PRIMARY OBJECTIVE:

      I. To determine the 2-year progression-free survival (PFS) for haploidentical, matched or
      mismatched, related or unrelated reduce intensity allogenic hematopoietic stem cell
      transplantation (allo HSCT) in relapsed multiple myeloma (MM) patients.

      SECONDARY OBJECTIVES:

      I. To determine 2 year overall survival (OS). II. To determine the cumulative incidence of
      grade II-IV acute-graft-versushost-disease (aGVHD) at day 100 and 180.

      III. To determine the 100 days, 1 year and 2 year cumulative incidence of treatment-related
      mortality (TRM).

      IV. To assess one-year GVHD-free relapse-free survival (GRFS). V. To determine the cumulative
      incidence of chronic graft-versus-hostdisease (cGVHD) Va. To assess overall and best response
      rates 100 days after allo HCT, 3 months, 6 months and every 6 months thereafter until end of
      daratumumab maintenance.

      VI. To determine rate of relapse after allo HSCT followed by maintenance. VII. To determine
      rate of minimal residual disease (MRD) negativity using next generation sequencing (Food and
      Drug Administration [FDA] approved) in patients achieving a very good partial response (VGPR)
      or better.

      CORRELATIVE OBJECTIVE:

      I. To determine immune reconstitution pattern on days +30, +100, +180 and +365 following allo
      HSCT.

      OUTLINE:

      Patients receive fludarabine intravenously (IV) on days -5 to -2 and melphalan IV on days -3
      to -2, then undergo stem cell transplantation on day 0. Patients receive cyclophosphamide on
      days 3 and 4, tacrolimus orally (PO) or twice daily (BID) or IV starting on day 5, and
      mycophenolate mofetil IV or PO three times daily (TID) on days 5 to 35. Patients also receive
      daratumumab IV starting between day 90-150 for up to 1 year. Treatment continues in the
      absence of disease progression or unacceptable toxicity.

      After completion of study treatment, patients are followed up periodically for up to 2 years
      post stem cell transplantation.

Maximum Eligible Age:75 Years

Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:2-year progression-free survival (PFS)
Time Frame:From the date of transplant until the date of relapse or date of death from any cause, assessed at 2 years
Safety Issue:
Description:Patients who do not relapse or die will be censored at the date of last clinical assessment. Kaplan-Meier curves will be generated to estimate the PFS rates at 2 years posttransplant. To evaluate the potential association between patient characteristics and PFS, the log-rank test will be used to compare the PFS curves and Cox proportional hazard regression model will be used to estimate the hazard ratio.

Secondary Outcome Measures

Measure:Incidence of adverse events
Time Frame:Up to 2 years post-transplant
Safety Issue:
Description:Adverse events by grade will be summarized. The occurrence of grade 3+ adverse events according to Common Terminology Criteria for Adverse Events (CTCAE) will be summarized as well. Adverse events will initially be reviewed regardless of attribution, but also according to whether adverse events are possibly, probably, or definitely related to treatment.
Measure:Cumulative incidence of grade II-IV acute graft-versus host disease (GvHD (aGVHD)
Time Frame:Up to 6 weeks
Safety Issue:
Description:The event will be onset of grade II-IV aGvHD and time to aGvHD will be defined as the period of time from transplantation to the event of aGvHD. Death and early relapse without aGvHD will be competing risks. Cumulative incidence rate of aGVHD with 95% confidence intervals will be estimated from the cumulative incidence curves. To evaluate the association between patient characteristics and aGVHD, the Gray's test accounting for competing risks will be used to compare the cumulative incidence curves and a proportional hazards model for the sub distribution of competing risks will be used to estimate the hazard ratio. The cumulative incidence of chronic GVHD (cGVHD) will be similarly analyzed.
Measure:Rate of relapse
Time Frame:From the date of transplant to relapse treating death from any cause as a competing risk, assessed up to 2 years
Safety Issue:
Description:Patients without relapse or death will be censored at last clinical assessment date. The similar analysis approach used for outcome of aGVHD will be applied.
Measure:Overall survival (OS)
Time Frame:From the date of transplant to death or last contact date if no death, assessed up to 2 years
Safety Issue:
Description:A similar analysis approach described above for PFS will be applied for the OS analysis.
Measure:1- year GVHD-free Relapse-free Survival (GRFS)
Time Frame:From the date of transplant until the date of grade II-IV acute GVHD, chronic GVHD, disease relapse or progression, or death from any cause, whichever occurs first, assessed at 1 year
Safety Issue:
Description:Patients who do not experience an event will be censored at the date of last clinical assessment. A similar analysis approach described above for PFS will be applied for the GRFS analysis.
Measure:100-day cumulative incidence of treatment-related mortality (TRM)
Time Frame:From the date of transplant to date of death, assessed up to 100 days
Safety Issue:
Description:The event will be death due to reasons other than disease. The competing risk for non relapsed mortality (NRM) will be death due to disease. The cumulative incidence curve accounting competing risks will be generated to estimate the cumulative incidence rate at various time points.
Measure:1-year cumulative incidence TRM
Time Frame:From the date of transplant to date of death, assessed at 1 year
Safety Issue:
Description:The event will be death due to reasons other than disease. The competing risk for NRM will be death due to disease. The cumulative incidence curve accounting competing risks will be generated to estimate the cumulative incidence rate at various time points.
Measure:2-year cumulative incidence of TRM
Time Frame:From the date of transplant to date of death, assessed at 2 years
Safety Issue:
Description:The event will be death due to reasons other than disease. The competing risk for NRM will be death due to disease. The cumulative incidence curve accounting competing risks will be generated to estimate the cumulative incidence rate at various time points.
Measure:Overall response rate
Time Frame:Up to 2 years post-transplant
Safety Issue:
Description:The proportion of each type of response with a 95% confidence interval (CI) will be reported for all evaluable patients, assuming a binomial distribution.
Measure:Best response rate
Time Frame:Up to 2 years post-transplant
Safety Issue:
Description:The proportion of each type of response with a 95% CI will be reported for all evaluable patients, assuming a binomial distribution.
