Irradiated Donor Cells Following Stem Cell Transplant in Controlling Cancer in Patients With Hematologic Malignancies

PRIMARY OBJECTIVES:

I. To determine the toxicity associated with the administration of irradiated haploidentical
cells (IHC) to patients with high-risk hematologic malignancies.

SECONDARY OBJECTIVES:

I. To determine if there is evidence of disease response associated with IHC.

TERTIARY OBJECTIVES:

I. To determine if treatment with the irradiated cells induces an immune response targeting
tumor associated epitopes.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT I: Within 42 days after hematopoietic engraftment (both neutrophils and platelets)
after autologous hematopoietic stem cell transplantation (HSCT), patients receive initial
treatment with IHC. Patients that do not have evidence of relapse or progressive disease may
be treated every 8-12 weeks for up to 3 doses.

COHORT II: Patients with high-risk disease receive initial treatment with IHC within 70 days
after hematopoietic engraftment (both neutrophils and platelets) after allogeneic HSCT.
Patients being treated for relapsed disease may receive initial treatment with IHC any time
after relapse is documented. Patients that do not have evidence of relapse or progressive
disease may be treated every 8-12 weeks for up to 3 doses.

After completion of study treatment, patients will be followed up within 8 weeks.

Inclusion Criteria:

- Patient with disease (stage) eligible per cohort

and ?high-risk? disease as defined below:

World Health Organization [WHO] subtypes) not in computed tomography
(CT)-positron emission tomography (PET) complete remission at time of high dose
therapy

- Diffuse large cell lymphoma with ?double hit? or ?double expressor? features

- Diffuse large cell lymphoma or peripheral T cell lymphoma (including WHO
specified subtypes) refractory to standard induction therapy OR relapsing within
1 year of treatment OR in greater that second complete remission (CR)

- Mantle cell lymphoma not in CR1

- Multiple myeloma with ONE (or more) of the following high risk features:

- Less than very good partial remission at time of high dose therapy

- High Revised-International Staging System (R-ISS) (stage III ? 2
microglobulin >= 5.5 plus lactate dehydrogenase [LDH] > upper limit of
normal [ULN] and/or del17p, t(4;14), t(14;16)) at time of diagnosis

- Cytogenetics or fluorescent in situ hybridization (FISH) del17p

- COHORT 2: patients with high risk disease having undergone an allogeneic hematopoietic
stem cell transplant from a 10/10 human leukocyte antigen (HLA) matched donor with one
of the following disease subtypes:

- Acute myeloid leukemia (AML) in CR1 with high risk features (European Leukemia
Network [ELN]) at presentation

- Diagnostic sample with either t(6;9), t(9;22), 11q23, inv 3, -5, -7, del17p,
complex cytogenetics, NPMwt-flt3ITD+, OR p53 mutation (mut); patients whose
samples have mutations in RUNX1 or ASXL1 are also eligible (unless the
patient has favorable cytogenetics)

- AML in CR1 with measurable minimal residual disease (MRD) by molecular (e.g.,
myeloid mutation profile, polymerase chain reaction [PCR] for NPM1, core-binding
factor [CBF], mixed lineage leukemia [MLL]) or flow cytometry

- AML not in CR1 (including patients with morphologic CR but with incomplete
recovery, CRi)

- Myelodysplastic syndrome (MDS) with complex cytogenetics, 17p deletion or p53
mutation, or JAK2 or RAS mutation

- Treatment-related MDS or AML

- Acute lymphoblastic leukemia (ALL) not in CR1

- ALL with MRD

- Any hematologic malignancy relapsed or with persistent disease after allogeneic
hematopoietic stem cell transplant

- Multiple myeloma

- Non-Hodgkin lymphoma (NHL) with chemoresistant disease at time of transplant

- Any patient undergoing allogeneic hematopoietic stem cell transplant and an
anticipated rate of relapse > 80% based upon published data and for which there
is consensus amongst the Hematologic Malignancies Tumor Study Group that
enrollment is appropriate

- Availability of a genetic child, genetic parent or sibling as a potential HLA
haploidentical donor

- Meets standard eligibility requirements for high dose chemotherapy with autologous
stem cell rescue (COHORT 1) or allogeneic hematopoietic stem cell transplant (COHORT
2) and has signed consent for those procedures

- DONOR: Donor must be related to patient and be partially (>= 3/6 antigen) HLA-matched

Blood Center screening history and laboratory studies)
