About this trial

Background:

People with blood cancers often receive blood or bone marrow transplants. But even with these treatments, the risk of relapse is high. Researchers want to see if giving the transplant recipient an infusion of lymphocytes (a type of white blood cell) from their transplant donor early after the transplant can reduce that risk.

Objective:

To learn if giving donor lymphocytes early after a transplant will help reduce the risk of relapse for people with certain blood cancers.

Eligibility:

Adults aged 18-65 with high-risk leukemia, lymphoma, myelodysplastic syndrome, or multiple myeloma that does not respond well to standard treatments and/or has a high risk of relapse. Healthy potential bone marrow and lymphocyte donor relatives aged 12 and older are also needed.

Design:

Participants will be screened with:

Physical exam

Blood and urine tests

Spinal tap

Eye exam

Dental exam

Heart and lung tests

Imaging scans. A radioactive substance may be injected in their arm if a PET scan is needed.

Bone marrow aspiration and biopsy

Some screening tests will be repeated during the study.

Participants will stay at the NIH hospital for about 4 weeks. They will receive a central venous catheter. They will get chemotherapy and other drugs starting 6 days before transplant. Then they will have their transplant. They will receive donor white blood cells 7 days later. They will give blood, bone marrow, urine, and stool samples for research. They must stay near NIH for at least 100 days after transplant.

Participants will have periodic follow-up visits for 5 years.

Healthy donors will have 2-3 visits. They will give blood, bone marrow, white blood cells, and stool samples for research.

Participation will last for 5 years....

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Acute myeloid leukemia (AML) with favorable cytogenetics (t(8;21), inv(16), t(15,17)) with induction failure (persistent disease without first achieving remission of any type) or active relapse

AML with intermediate cytogenetics (not classified as favorable or adverse) with induction failure or active relapse (AML with intermediate cytogenetics in morphologic complete remission [CR] with minimal residual disease detectable by any modality also will be eligible)

AML with adverse cytogenetics (complex karyotype with >= 4 abnormalities) regardless of remission status

Low risk myelodysplastic syndrome (MDS) (<= 5% blasts, including chronic myelomonocytic leukemia) with adverse cytogenetics (abnormal chromosome 7 or >= 4 abnormalities) with induction failure or active relapse

Disqualifiers

Subjects who are receiving any other investigational agents. Prior experimental therapies must have been completed at least 3 weeks prior to the date of beginning conditioning.

Prior myeloablative conditioning for autologous or allogeneic HCT.

Active breastfeeding.

Active malignancy of non-hematopoietic type (excluding non-melanoma skin cancers) which is metastatic, relapsed/refractory to treatment, or locally advanced and not amenable to curative treatment. This excludes non-melanoma skin cancers.

Trial design

Design model

Sequential

Treatments tested in this trial

  • donor lymphocyte infusion

    Procedure/Surgery

    The DLI will be given on Day +7 (Day +21 for dose level -1). If a recipient participant is deemed too critically ill/unstable to receive DLI on the protocol specified day, the DLI will be delayed up to 4 days at the discretion of the PI and given within this time frame once the recipient participant s clinical status has stabilized or improved. If the DLI cannot be given during this time frame, the recipient participant will be taken off study and not considered evaluable for DLT, outcomes, or adverse events since the experimental intervention will not have been given.

  • Cyclophosphamide

    Drug

    HLA-matched: 50 mg/kg IV once daily over 2 hours on days +3 and +4a Cyclophosphamide will be dosed according to ideal body weight. HLA haploidentical: 25 mg/kg IV once daily over 2 hours on days +3 and +4a Cyclophosphamide will be dosed according to ideal body weight.

  • Busulfan

    Drug

    AUC targeted dose based on busulfan test dose, with a default dose of 130 mg/m2/day, given as IV infusion over 3 hours each day for 4 days Transplant days -6 through day -3

  • Mycophenolate mofetil

    Drug

    15 mg/kg orally or IV three times daily (max 1000 mg/dose) starting on day +5, continued through day +35. Dosing will be according to actual body weight.

  • Fludarabine

    Drug

    40 mg/m2 IV infusion over 30-60 minutes once daily for 4 days Transplant days -6 through -3

  • Sirolimus

    Drug

    Loading dose of 6 mg orally given on day +5 (calculated based on actual body weight, maximum initial dose 6 mg), then maintenance dose starting at 2 mg orally daily on day +6 with dose adjustments to maintain a trough of 5-12 ng/ml, continued through day +70 with no taper. Doses should be modified as appropriate for drug interactions.
