Allogeneic Stem Cell Transplantation

Issa F. Khouri, MD

The goal of this clinical research study is to see if low intensity chemotherapy given together with the new drug 90Y Zevalin, followed by a transplant of blood or marrow stem cells from a donor can increase the length of remission in patients with leukemia and lymphoma. The safety of this treatment will also be studied.

Rituxan is an antibody made from human and mouse protein. It reacts with a certain antigen on lymphoma cells and causes the body's immune system to destroy the lymphoma cells. 90Y Zevalin and 111In Zevalin are murine-based antibodies combined with a radioactive agent that can also destroy lymphoma cells. Unlike Rituxan, 90Y Zevalin cannot be traced by regular scanning and requires indium to determine its distribution through the body.

Before treatment starts, patients will have a physical exam, including blood tests and urine tests. Women who are able to have children must have a negative blood pregnancy test. Bone marrow samples will be taken. For bone marrow sampling, a large needle is placed in the hipbone after it has been numbed. The bone marrow is then withdrawn through the needle. Patients will have a chest x-ray, computed tomography (CT) scans, an EKG, and tests of lung function.

Blood tests, urine tests, bone marrow sampling, and x-rays will be done as needed to track the effects of the transplant. Patients will have transfusions of blood and platelets as needed. Blood tests will be done daily while patients are in the hospital.

Patients in this study will receive an unlabeled antibody form of Y2B8 called rituxan by vein followed by a dose of 111In Zevalin by vein. 111In Zevalin includes the radioactive agent indium, which shows up when patients have x-rays or scans. The scans can show where and how fast the drug travels in the body and how long the drug stays in the body. Doctors need to be able to see how much of the drug goes to the tumor and how much goes to normal organs to see if it is safe to give 90Y Zevalin on an outpatient basis. A scan will be taken 48 to 72 hours after 111In Zevalin is given.

If the radiation in the 111In Zevalin is not a threat to normal organs and bone marrow, patients may receive 90Y Zevalin. Seven days after the 111In Zevalin injection, patients will receive a second dose of rituxan followed by a dose of 90Y Zevalin.

Patients will also receive fludarabine and cyclophosphamide daily for 3 days. All of the chemotherapy drugs will be given through a catheter (plastic tube) that extends into the large chest vein. The catheter will be left in place throughout treatment. When chemotherapy is finished, blood stem cells from a donor will be given through the catheter. Granulocyte colony-stimulating factor (G-CSF or GCSF), a hormone that helps the production of blood cells, will be injected under the skin once a day until the neutrophil counts recover in the blood. Patients will receive methotrexate for 3 days post transplant and tacrolimus for 6 months or more to prevent graft versus host disease.

All patients will have complete checkups, including blood and urine tests 2 or 3 times during the first 12 weeks of the study. Tumors will be measured by CT or MRI and gallium scans. Patients will be asked to fill out a survey about quality of life issues (maintaining normal routine, family life, social life, pain). It takes about half an hour to fill out the survey. A bone marrow sample may be taken. A test of heart function will be done. Checkups and tests will be done every 3 months for 1 year and then every 6 months for 4 more years.

Treatment will be given in the hospital at M. D. Anderson. Patients will need to stay in the hospital for about 3 to 4 weeks. Patients must stay in the Houston area for about 100 days after the transplant. After that, patients will need to return to Houston from time to time for blood tests, urine tests, and other exams.

This is an investigational study. 90Y-Zevalin is approved by the FDA for relapsed and refractory lymphoma. Its use in this trial, however, is investigational. About 70 patients will take part in this study. All will be enrolled at M. D. Anderson.

Th2 cells in allo HSCTT

Th2 Cells

Daniel H Fowler, M.D.

Allogeneic peripheral blood stem cell transplantation (PBSCT) is primarily limited by graft-versus-host disease (GVHD). In murine models, we have demonstrated that donor CD4+ T cells of Th1 cytokine phenotype (defined by their secretion of IL-2 and IFN-gamma) mediate GVHD. In contrast, donor CD4+ T cells of Th2 phenotype (defined by their secretion of IL-4, IL-5, and IL-10) do not generate GVHD, and abrogate Th-1-mediated GVHD. Importantly, we have demonstrated that enrichment of murine allografts with Th2 cells reduces GVHD without impairing the ability of donor T cells to prevent graft rejection. These studies indicate that the administration of Th2 cells after allogeneic transplantation represents a strategy for achieving alloengraftment with reduced GVHD.

In addition to GVHD, allogeneic PBSCT has been limited by the toxicity associated with conventional myeloablative preparative regimens. Such regimens, which typically utilize total body irradiation (TBI) and high-dose chemotherapy, were once considered essential for the prevention of graft rejection. However, recent clinical studies have shown that non-myeloablative doses of fludarabine-based chemotherapy can result in alloengraftment. In murine models, we have demonstrated that severe host T cell depletion induced by combination fludarabine and cytoxan can prevent even fully-MHC mismatched marrow graft rejection. Although non-myeloablative regimens may reduce regimen-related toxicity, such transplants have been associated with a 30 to 40% incidence of severe acute GVHD that is similar to rates observed with myeloablative regimens. Because non-myeloablative regimens appear to be associated with reduced regimen-related toxicity, we have elected to conduct this phase I study of Th2 cells in the setting of an immunoablative (non-myeloablative) preparative regimen.

Patients with leukemia in clinical remission, and patients with refractory lymphoid malignancy will be candidates for this HLA-matched allogeneic PBSCT protocol. Patients will receive novel induction regimen (fludarabine and EPOCH) and transplant preparative regimen (fludarabine and cytoxan) designed to maximally deplete host immune T cells capable of mediating graft rejection. After induction and preparative regimen chemotherapy, patients will receive an unmanipulated, G-CSF mobilized PBSC graft. In the initial six patients receiving this transplant procedure at the NCI, graft rejection has been successfully prevented (100% donor chimerism by day 30 post-transplant). Importantly, GVHD has been observed in all six patients, with three of the six patients developing severe GVHD (grade III). Given that this regimen successfully achieves donor engraftment, and is associated with significant GVHD, this transplant regimen represents an excellent clinical setting for the evaluation of Th2 cells.

Using this non-myeloablative allogeneic PBSCT approach, we will perform a Phase I study to evaluate the safety and feasibility of administering donor Th2 cells on day 1 post-transplant. Prior to transplantation, donor CD4+ T cells will be stimulated in vitro using culture conditions that support the generation of donor CD4 cells of the Th2 cytokine profile. If this Phase I study demonstrates that Th2 cell administration is safe and feasible, a Phase III study will be performed to evaluate whether Th2 cell administration reduces the incidence and severity of GVHD. Successful implementation of this Th2 strategy will greatly reduce the morbidity and mortality associated with allogeneic PBSCT, and may also represent an approach to stem cell transplantation in patients lacking an HLA-matched donor.

Allogeneic peripheral blood stem cell transplantation (PBSCT) is primarily limited by graft-versus-host disease (GVHD). In murine models, we found that donor CD4+ Th1 cells (secretion of IL-2 and IFN-Gamma) mediate GVHD. In contrast, donor Th2 cells (secretion of IL-4 and IL-10) do not generate GVHD, and abrogate Th1-mediated GVHD. We also found that murine allografts enriched with Th2 cells reduced GVHD without impairing the ability of donor T cells to prevent graft rejection. These studies indicate that donor Th2 cells may be a new approach to reducing GVHD.

In addition to GVHD, allogeneic PBSCT has been limited by toxicity associated with conventional myeloablative preparative regimens. Although non-myeloablative regimens may reduce regimen-related toxicity, such transplants have been associated with a 30 to 40% incidence of severe acute GVHD (similar to rates observed with myeloablative regimens). Because non-myeloablative regimens appear to have reduced regimen-related toxicity, we have conducted this pilot study of Th2 cells in the setting of an immunoablative (non-myeloablative) preparative regimen.

In this protocol, patients with lymphoid or hematologic malignancy receive induction therapy (fludarabine and EPOCH) and transplant chemotherapy (fludarabine and cytoxan) to deplete host T cells that mediate graft rejection. In our initial NCI cohort receiving HLA-matched sibling, G-CSF mobilized PBSCT on this protocol (n=19), graft rejection was prevented in all cases, with most recipients having 100% donor chimerism by day 28 post-SCT. With this reduced intensity regimen, GVHD remained a significant complication, with 6/19 recipients having grade II and 6/19 recipients having grade III acute GVHD. Importantly, potent graft-versus-tumor responses were observed, with 9/19 patients remaining in complete remission at a median of 17 months post-SCT.

Given that this allogeneic SCT regimen achieves engraftment and durable anti-tumor responses, yet is associated with GVHD, this protocol represents an appropriate setting for evaluation of donor Th2 cells. Initial patients will receive Th2 cells in a phase I manner. Three patients will receive 5 x 10(6) Th2/kg, six patients will receive 2.5 x 10(7) Th2/kg, and six patients will receive 1.25 x 10(8) Th2/kg. The highest dose of Th2 cells that results in an acceptable toxicity profile (not more than 1/6 serious adverse events) and a favorable rate of acute GVHD (not more than 2/6 cases of grade II or greater acute GVHD) will be selected for the phase II study arm. Eighteen patients will be treated with allogeneic SCT and Th2 cells on this phase II study arm. In the event that Th2 recipients have reduced GVHD, further clinical trials involving Th2 cells will be warranted.

The purpose of this study is to determine whether the histone deacetylase inhibitor CHR-2845 is tolerated in patients with haematological diseases and lymphoid malignancies.

CHR-2845 is a novel type of histone deacetylase inhibitor (HDACi) for use in cancer that, in addition to having broad ranging anti-proliferative activity against transformed cells, is designed to have an increased therapeutic window against diseases which involve cells of the monocyte-macrophage lineage. There are several HDACi's in clinical development and one, SAHA (Vorinostat, Zolinza®), has recently been approved for use in the treatment of cutaneous T-cell lymphoma. CHR-2845 is a cell-permeant ester that is metabolised to give an active acid, CHR-2847, which selectively accumulates in monocytes and macrophages. This results in a 20-100 fold increase in anti-proliferative potency of CHR-2845 for monocytic over non-monocytic tumour cells. This selectivity should lead to an increased therapeutic window in haematological malignancies involving cells of the monocyte lineage (AML M4, AML M5 and CMML). In addition, there is increasing evidence that monocytes and macrophages associated with some haematological tumours (tumour-associated macrophages (TAMs)) are involved in supporting the growth and spread of the tumour. This clinical trial will focus on haematological and lymphoid malignancies with the intention of evaluating the safety and tolerability of CHR-2845. Additionally it will compare response in patients where monocytes/macrophages are important disease drivers, with the response in other patients. This will allow an early determination of the potential improvement in therapeutic window afforded by the monocyte/macrophage directed HDACi activity.

Background:

* Of the several drugs and drug combinations approved for treatment of relapsed and refractory chronic lymphocytic leukemia (CLL), the reported complete response rates are no greater than 30%.
* Obinutuzumab is a glycoengineered, humanized type 2 anti-cluster of differentiation 20 (CD20) monoclonal antibody thought to engage the immune system by directly activating antibody-dependent, cell mediated cytotoxicity (ADCC); it is approved for treatment of chronic lymphocytic leukemia in combination with chlorambucil.
* The key mediators of ADCC are polymorphonuclear neutrophils, monocytes, and natural killer (NK) cells.
* Recombinant human Interleukin-15 (rhIL-15) is a stimulatory cytokine that promotes the differentiation and activation of NK cells, monocytes, and long-term cluster of differentiation 8 (CD8) + memory T-cells. In a Phase I trial, administration of rhIL-15 as a 5-day continuous intravenous infusion (civ) was associated with up to 45-fold increase in the number of NK cells at well tolerated dose levels.
* Preclinical murine lymphoid malignancy models have shown increased efficacy of monoclonal antibodies when administered together with recombinant human Interleukin-15 (rhIL-15); BL/6 mice inoculated with EL4 murine T-cell lymphoma expressing human cluster of differentiation 20 (EL4-CD20) cells (a syngeneic lymphoma line); including significant prolongation of survival with the IL-15/Rituximab combination compared to either drug given as single agent (90% v. 30% alive at 75 days).

Objectives:
