Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

If transplantation using mismatched unrelated donors or non-first-degree relatives could be performed with an acceptable toxicity profile, an important unmet need would be served. Towards this goal, the current study extends our platform of nonmyeloablative, partially HLA-mismatched bone marrow transplant (BMT) and Peripheral Blood Stem Cell Transplant (PBSCT) to the use of such donors, investigating up to several postgrafting immunosuppression regimens that incorporate high-dose Cy. Of central interest is the incorporation of sirolimus into this postgrafting immunosuppression regimen.

The primary goal for phase 1 is to identify a transplant regimen associated with acceptable rates of severe acute GVHD and NRM by Day 100 and for phase 2 estimate the 6-month probability of survival without having had acute grade III- IV GVHD or graft failure.

* patients with transformed lymphomas must have stable disease or better.
9. Poor-risk CLL or SLL as follows:

* 11q deletion disease that has progressed after a combination chemotherapy regimen,
* 17p deletion disease,
* or histologic conversion;

* diffuse large B-cell lymphoma or its subtypes, excluding primary CNS lymphoma
* primary mediastinal large B-cell lymphoma
* large B-cell lymphoma, unspecified

6. One of the following, in order to lower risk of graft rejection:

* Cytotoxic chemotherapy, an adequate course of 5-azacitidine or decitabine, or alemtuzumab within 3 months prior to start of conditioning; or
* Previous BMT within 6 months prior to start of conditioning.

NOTE: Patients who have received treatment outside of these windows may be eligible if it is deemed sufficient to reduce graft rejection risk; this will be decided on a case-by-case basis by the PI or co-PI.
7. Any previous BMT must have occurred at least 3 months prior to start of conditioning.
8. Adequate end-organ function as measured by:

1. Left ventricular ejection fraction greater than or equal to 35%, or shortening fraction \> 25%, unless cleared by a cardiologist

3. FEV1 and FVC \> 40% of predicted; or in pediatric patients, if unable to perform pulmonary function tests due to young age, oxygen saturation \>92% on room air
9. ECOG performance status \< 2 or Karnofsky or Lansky score \> 60


1. Potential donors consist of:

* Unrelated donors
* Second-degree relatives
* First cousins
2. The donor and recipient must be identical at at least 5 HLA alleles based on high resolution typing of HLA-A, -B, -Cw, -DRB1, and -DQB1, with at least one allele matched for a HLA class I gene (HLA-A, -B, or -Cw) and at least one allele matched for a class II gene (HLA-DRB1 or -DQB1).
3. Meets institutional selection criteria and medically fit to donate. 4 . Lack of recipient anti-donor HLA antibody. Note: In some instances, low level, non-cytotoxic HLA specific antibodies may be permissible if they are found to be at a level well below that detectable by flow cytometry. This will be decided on a case-by-case basis by the PI and one of the immunogenetics directors. Pheresis to reduce anti-HLA antibodies is permissible; however eligibility to proceed with the transplant regimen would be contingent upon the result.

Exclusion Criteria

* Not pregnant or breast-feeding.
* No uncontrolled bacterial, viral, or fungal infection.

* Note: HIV-infected patients are potentially eligible. Eligibility of HIV-infected patients will be determined on a case-by-case basis.
* No previous allogeneic BMT (syngeneic BMT permissible).
* Active extramedullary leukemia or known active CNS involvement by malignancy. Such disease treated into remission is permitted.


* Donor must not be HLA identical to the recipient.
* Has not donated blood products to recipient.
