Clinical Trial Summary

This study seeks to examine the investigational use of the conditioning regimen (bendamustine, fludarabine, and rituximab) prior to haploidentical peripheral blood allogeneic stem cell transplantation with Post-Transplant Cyclophosphamide. The study will also test the investigational use of CD56-enriched Donor Lymphocyte Infusion to see if this treatment is safe, and whether or not it will help patients achieve better outcomes post-transplant, including reduced risk of Graft-Versus-Host Disease (GVHD), and preventing disease relapse.

Description:

This is a single center Phase I trial of a new haploidentical stem cell transplant regimen intended to assess safety. Two groups of patients are planned: patients with lymphoma and patients with multiple myeloma. Each subject will receive a haploidentical stem cell transplantation using peripheral blood stem cells. Bendamustine-fludarabine-rituximab-TBI conditioning will be used, followed by stem cell infusion, with Post-Transplant Cyclophosphamide and tacrolimus for GVHD prophylaxis. Patients will receive a CD56-selected DLI on day +8. Evaluations will be taken at baseline and at each of the study visits. Screening data will be reviewed to determine subject eligibility. Subjects who meet all inclusion criteria and none of the exclusion criteria will be entered into the study. Total duration of subject participation will be one year. Total duration of the study is expected to be three years.

Recruitment information / eligibility

• Status: Active, not recruiting
• Enrollment: 30
• Est. completion date: November 2031
• Est. primary completion date: November 7, 2021
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 75 Years

Eligibility

General Inclusion Criteria (For Treatment Groups)

• Patient age 18 - 75 years

• ECOG 0 - 2

• HIV-positive patients are allowed if these criteria are met:

1. No history of opportunistic infections

2. CD4+ cell count greater or equal to 250 cells/mm3

3. No history of non-malignancy AIDS-defining conditions other than historical low CD4+ cell counts

4. Patient is on antiretroviral therapy with undetectable viral load. There must be minimal interactions of the antiviral therapy with the experimental treatment (antiretroviral such as ritonavir is potent CYP3A4 inhibitor and p-gp inducer may interact with tacrolimus resulted in increased serum concentration of tacrolimus).

• Patients must have a related donor or who is at minimum HLA haploidentical. The donor and recipient must be identical at least one allele of each of the following genetic loci: HLA-A, HLA-B, HLA-Cw, HLA-DRB1, and HLA-DQB1. A minimum match of 5/10 is therefore required, and will be considered sufficient evidence that the donor and recipient share one HLA haplotype. An unrelated donor search is not required. (Patients with a readily-available, suitable, fully-matched sibling donor less than age 55 are not eligible for this trial, these patients should proceed to transplant using the matched related donor as standard-of-care).

Criteria for Donor Eligibility

• Age greater than 12 years

• Donors must meet the selection criteria as defined by the Foundation for the Accreditation of Hematopoietic Cell Therapy (FACT).

• In the event that two or more eligible donors are identified, the following order of priority will be used to determine the preferred donor:

• Medically and psychologically fit and willing to donate

• For CMV seronegative recipients, a CMV seronegative donor

• Red blood-cell compatibility

• RBC cross-match compatible

• Minor ABO incompatibility

• Major ABO incompatibility

• If more than one preferred donor is identified and there is no medical, HLA- or KIR ligand reason to prefer one of them, then the following guidelines are recommended:

If the patient is male, choose a male donor:

• Choose the youngest preferred donor

• If the patient and family express a strong preference for a particular donor, use that one.

Inclusion Criteria (Lymphoma)

• Diagnosis of resistant or relapsed CLL, Non-Hodgkin Lymphoma, Hodgkin Lymphoma, T-cell lymphoma, NK or NK/T Lymphoma.

• Meets one of the following criteria:

• relapsed after auto-transplant, or

• failed to mobilize autologous stem cells, or

• for whom allogeneic stem cell transplant is deemed appropriate given disease risk factors that make cure with autologous transplant seem unlikely, such as history of chemotherapy refractoriness, high risk disease features/mutations/translocations (e.g., Double Hit / Double Expressor DLBCL), short remission after prior chemotherapy, or histologic transformation (see below).

• For Patients with Aggressive Mantle Cell and Diffuse Large B Cell Lymphoma who have not had a prior autologous transplant:

• Must have received at least 2 lines of prior therapy, and

• Have been exposed to anthracycline, and

• High and High-Intermediate aaIPI score (2 or 3 factors), and

• Have relapsed within one year of primary therapy

• For diagnosis of other aggressive lymphoma (e.g. NK/T Lymphoma, T Cell

Lymphoma, etc.):

• Must have received at least 2 lines of prior therapy, and

• Relapsed within 12 months of most recent therapy

• For low-grade lymphomas / CLL:

• Standard risk patients (absence of del(17p), absence of del(11q), no TP53 mutation and absence of complex karyotype) must have progressed on BCR inhibitor, or undergone histologic transformation, to be eligible.

• Patients with high risk disease (del(17p) or TP53 mutations and/or complex phenotype) who relapse after frontline therapy, demonstrate refractory disease to second line therapy (not BCR inhibitors), but show an objective response to BCR inhibitors are eligible to be taken off BCR inhibitors in order to proceed to alloHSCT on trial. Patients with high risk disease who relapse after frontline therapy, demonstrate refractory disease to second line therapy including BCR inhibitors (not BCL-2 inhibitors), but show an objective response to BCL-2 inhibitors (venetoclax) are eligible to be taken off BCL-2 inhibitors in order to proceed to alloHSCT on trial.

• For aggressive lymphomas, partial or complete remission (PR or CR) is required prior to alloHSCT.

• Regarding CD20 expression: Patients with B cell malignancies that were CD20+ at any level at the time of relapse diagnosis (including partial / dim staining on IHC or partial / low level expression by flow cytometry) will receive rituximab as part of allogeneic transplant conditioning, if indicated. Patients with primary-refractory disease who were CD20+ at any level at the time of diagnosis will likewise receive rituximab, if indicated. Patients with histologies that were CD20- will not receive rituximab (T cell lymphoma, NK/T lymphoma, etc.). Fresh tissue / repeat biopsy is not required; the most recent biopsy will be reviewed to assess CD20 status.

Inclusion Criteria (Multiple Myeloma)

• Patient age 18 - 75 years with:

• Early relapse (less than 24 months) after primary therapy that included an autologous HSCT, or

• High risk multiple myeloma defined as t(4;14), del(17p), -13, t(14;16), amp (1q21), chromosome 8q24.1/c-MYC abnormality, or LDH > ULN at diagnosis, provided patients respond favorably to salvage therapy before enrollment for alloHSCT on trial and patient is age < 55, or

• Patients failing to mobilize peripheral blood stem cells for autologous transplantation, or

• Extramedullary disease at diagnosis or relapse, or

• Plasma-cell leukemia with chemosensitive disease
