Premature closure due to inability to accrue to ARM IVD, cohorts 1 and 2

Background:

Patients with cancers of the blood and immune system often benefit from transplants of stem cells from a genetically well-matched sibling. However, severe problems may follow these transplants because of the high-dose chemotherapy and radiation that accompany the procedure. Also, donated immune cells sometimes attack healthy tissues in a reaction called graft-versus-host disease (GVHD), damaging organs such as the liver, intestines and skin. To reduce toxicity of high-dose preparative chemotherapy, this study performs allogeneic transplant after low doses of chemotherapy. In an attempt to improve anti-tumor effects without increasing GVHD, this study uses donor immune cells (T helper 2 (Th2) cells) grown in the laboratory; some patients will receive standard donor immune cells (not grown in laboratory). All patients will receive immune modulating drugs sirolimus and cyclosporine to prevent GVHD.

Objective:

To determine the safety, treatment effects and rate of GVHD in patients receiving transplants that use low-intensity chemotherapy, sirolimus plus cyclosporine, and transplant booster with either Th2 cells or standard immune cells.

Eligibility:

Patients 16 to 75 years of age with acute or chronic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, or myelodysplastic syndrome.

Patients must have a suitable genetically matched sibling donor and adequate kidney, heart and lung function.

Design: The protocol has three treatment groups: cohort 1, Th2 booster at two weeks post-transplant; cohort 2, standard T cell booster at two weeks post-transplant; cohort 3, multiple infusion of Th2 cells.

Condition: Hematologic Neoplasms, Myeloproliferative Disorders

Intervention: Biological; therapeutic allogeneic lymphocytes

Drug: Sirolimus

Study Type: Interventional

Study Design: Primary Purpose: Treatment

Phase: Phase II

Background

In protocol 99-C-0143, we evaluated a new approach to allogeneic hematopoietic stem cell transplant (HSCT) that involved intensive host T cell ablation and graft augmentation with in vitro generated donor T helper 2 (Th2) cells. Rapid full donor engraftment occurred with this regimen; however, grade II to IV acute graft versus host disease (GVHD) was not significantly reduced in Th2 cell recipients. In an attempt to improve clinical results using Th2 cell graft engineering, this second-generation Th2 cell clinical trial was developed that incorporates the following interventions: (1) In an attempt to reduce transplant-related toxicity, this protocol now uses a very low-intensity host preparative chemotherapy; (2) In an attempt to reduce GVHD, this study will utilize Th2 cells expanded in the presence of the immune modulation agent, rapamycin (sirolimus), as murine Th2 cells grown in rapamycin reduce GVHD more effectively than control Th2 cells; (3) To further reduce GVHD, subjects will receive a short-course of sirolimus therapy in addition to standard cyclosporine GVHD prophylaxis; and (4) Using this novel low-intensity transplant platform, compare in a preliminary manner the post-transplant outcome of patients receiving pre-emptive donor lymphocyte infusion (DLI) using either Th2 cells or unmanipulated donor T cells.

Objectives

In the setting of human leukocyte antigen (HLA)-matched sibling allogeneic HSCT using GVHD prophylaxis of cyclosporine and short-course sirolimus, compare in a preliminary manner the safety, feasibility, alloengraftment, clinical anti-tumor effects, and GVHD rate of low-intensity Preparative Chemotherapy with pre-emptive DLI using either Th2 cells or unmanipulated T cells at day 14 post-HSCT.

Eligibility

Subjects that are 16 to 75 years of age that have a suitable 6/6 HLA-matched sibling donor are potentially eligible. Subjects with a diagnosis of acute or chronic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, or myelodysplastic syndrome are potentially eligible. Adequate kidney, cardiac, and pulmonary function are required.

Design

• Patients age 18 or older with lymphoma (all types) or chronic lymphocytic leukemia will be randomized just prior to the transplant regimen to receive DLI with either donor Th2 cells (cohort 1) or unmanipulated T cells (cohort 2); n=10 patients will be accrued to each arm provided that stopping rules pertaining to excessive GVHD or graft rejection are not met. For these randomized patients, the preparative regimen will consist of low-intensity fludarabine (120 mg/m(2)) plus cyclophosphamide (1200 mg/m(2)) and GVHD prophylaxis will consist of short-course, high-dose sirolimus followed by maintenance cyclosporine. Cohorts 1 and 2 will be compared in a preliminary manner with respect to their post-transplant outcome, in particular: (a) conversion of mixed chimerism to predominant donor chimerism; (b) rate and severity of classical acute and late acute GVHD at the day 100 and day 180 post-transplant time points; and (c) time to induction of leukemia/lymphoma remission (if entering transplant with disease) or time to relapse (if entering transplant in remission).
• Patients with non-lymphoma diagnoses, patients with lymphoma that are under the age of 18 and lymphoma patients that are projected to be unable to complete the protocol-defined therapy through day 180 post-transplant will not be randomized but will be treated on cohort 3 (n=40), which will evaluate transplantation without the Flu/Cy preparative regimen and with pre-emptive Th2 cell DLI. The primary objective of cohort 3 is to evaluate whether transplantation without a preparative regimen will reduce the rate of acute GVHD associated with Th2 cell DLI from 41% (the rate observed with the fludarabine/cyclophosphamide (Flu/Cy) preparative regimen) to a rate of 15% (6 cases out of 40).

  14. Adequate central venous access potential.

  15. Potential patients referred for the study may not be eligible for the experimental protocol therapy due to reasons such as uncertainty about donor human leukocyte antigen (HLA) typing or need to control malignant disease, infection, or metabolic abnormality such as hypercalcemia on a emergent basis. Should a referred patient present to us in such a scenario, the patient will be referred back to their primary hematologist-oncologist for treatment. However, if referral back to the referring physician is not in the best interest of the patient according to the clinical judgement of the principal investigator (PI), then the patient may receive standard treatment for the malignant disease or complicating conditions (infection, metabolic problems under the current study. In other cases, a patient may have reasonable control of malignancy but does not meet the cluster of differentiation 4 (CD4) cell cut-off of 50 cells per microliter required for cohort 3 therapy; in such cases, standard care chemotherapy regimens may be administered for the specific goal of reducing the CD4 count (that is, immune depleting regimens such as the pentostatin plus cyclophosphamide combination, administered similar to the manner that we have developed on protocol 08-C- 0088). If it becomes apparent that the patient will not be able to proceed to experimental therapy, then he/she must come off study. Recipient-Subjects receiving a standard therapy, and availability of receiving the same treatment elsewhere, outside of a research protocol. Because such standard care therapy is not experimental, it is not necessary to complete the eligibility criteria prior to receiving such standard care; however, prior to initiation of the experimental therapy, the patient must meet each of the eligibility criteria detailed above. Attempts will be made to standardize such pretransplant chemotherapy (by administration of etoposide, prednisolone, oncovin, cyclophosphamide, hydroxydaunorubicin, fludarabine, rituximab (EPOCH-FR) chemotherapy, which is detailed later in this protocol); however, other regimens using approved agents will be allowed if such regimens are thought to be in the best interest of the patient.

INCLUSION CRITERIA: DONOR

1. First-degree relative with genotypic identity at 6/6 HLA loci (HLA- A, B, and DR).
2. Age 11 to 90 years and able to give consent or assent. For donors < 18 years old, the legal guardian must be able to provide informed consent.
3. Adequate venous access for peripheral apheresis, or consent to use a temporary central venous catheter for apheresis.
4. Donors must be human immunodeficiency virus (HIV) negative.
5. Donors with a history of hepatitis B or hepatitis C infection may be eligible. However, eligibility determination of such patients will require a hepatology consultation. The risk/benefit of the transplant and the possibility of transmitting hepatitis will be discussed with the patient and eligibility will then be determined by the principal investigator and lead associate investigator (LAI).
6. Lactating donors must substitute formula feeding for her infant during period of filgrastim administration (to prevent any filgrastim effect on infant).

EXCLUSION CRITERIA: PATIENT

1. Active infection that is not responding to antimicrobial therapy.
2. Active central nervous system (CNS) involvement by malignancy.
3. HIV infection (treatment may result in progression of HIV and other viral infections).
4. Chronic active hepatitis B. Patient may be hepatitis B core antibody positive. For patients with concomitant positive hepatitis B surface antigen, patient will require a hepatology consultation. The risk/benefit profile of transplant and hepatitis B will be discussed with the patient and eligibility determined by the principal investigator and Lead Associate Investigator.
5. Hepatitis C infection. Patient may have hepatitis C infection. However, each patient will require a hepatology consultation. The risk/benefit profile of transplant and hepatitis C will be discussed with the patient and eligibility determined by the principal investigator and Lead Associate Investigator.
6. Pregnant or lactating. Patients of childbearing potential must use an effective method of contraception. The effects of the chemotherapy, the subsequent transplant and the medications used after the transplant are highly likely to be harmful to a fetus. The effects upon breast milk are also unknown and may be harmful to the infant.
7. History of psychiatric disorder which may compromise compliance with transplant protocol, or which does not allow for appropriate informed consent.

EXCLUSION CRITERIA: DONOR

1. History of psychiatric disorder which may compromise compliance with transplant protocol, or which does not allow for appropriate informed consent.
2. History of hypertension that is not controlled by medication, stroke, autoimmune disease, or severe heart disease (donors with symptomatic angina will be excluded). Donors with a history of coronary artery bypass grafting or angioplasty who are symptom free will receive a cardiology evaluation and be considered on a case-by-case basis.
3. History of prior malignancy. However, cancer survivors who have undergone potentially curative therapy may be considered for stem cell donation on a case-by-case basis. In addition, donors with localized cancer such as prostate cancer that are on a watch-and-wait management due to the low-risk of disease progression may also be considered for stem cell donation on a case-by-case basis. The risk/benefit of the transplant and the possibility of transmitting viable tumor cells at the time of transplantation will be discussed with the patient.
4. Donors must not be pregnant (unknown effect of filgrastim on fetus). Donors of childbearing potential must use an effective method of contraception.
5. Anemia (Hemoglobin (Hb) less than 11 gm/dl) or thrombocytopenia (platelets less than 100,000 per microliter). However, potential donors with Hb levels less than 11 gm/dl that is due to iron deficiency will be eligible as long as the donor is initiated on iron replacement therapy and the case is individually approved by National Institutes of Health (NIH) or Hackensack Blood Bank.
