Specialized Blood Cell Transplants for Cancers of the Blood and Bone Marrow

• Status: Completed
• Trial end date: 2020-06-18
• Target enrollment: 0
• Participant gender: All

Summary

The are a variety of cancerous diseases of the blood and bone marrow that can be potentially cured by bone marrow transplantation (BMT). Diseases like leukemia, lymphoma, and multiple myeloma are among the conditions that can be treated with BMT.

Some patients with these diseases can be treated with medical chemotherapy alone. However, patients who relapse following chemotherapy are usually not curable with additional chemotherapy treatments. The only option known to provide a potential cure if this occurs is BMT.

Allogenic transplants are cells collected from relatives of the patient. The transplant requires additional high intensity chemotherapy and radiation in order to destroy cancerous cells. In the process, many normal bone marrow cells are also destroyed. This is the reason for transplanting stem cells. The stem cells help to build new functioning bone marrow, red cells, white cells, and platelets. In addition, the immune cells from the donor are implanted into the recipient s body and help to fight off infection and kill remaining cancerous cells.

Unfortunately, the powerful doses of chemotherapy and radiation therapy associated with allogenic BMT have toxic side effects and often make BMTs too dangerous to attempt in many patients.

In order to reduce the complications of BMT, and make it a safer available option for patients with cancers of the blood and bone marrow, researchers have developed a new approach to the BMT.

In this study researchers plan to use stem cells collected from the blood stream of patient s relatives rather than from the bone marrow (blood progenitor/stem cell transplant). In addition, researchers plan to use low doses of chemotherapy and no radiation therapy to reduce side effects. The majority of the cancer killing effect will be the responsibility of the stem cell transplant rather than the chemotherapy.

Criteria

• INCLUSION CRITERIA - Recipients:

Group A: Subjects at high risk for transplant related complications and mortality as defined below:

Ages 10 to 75 (both inclusive) with a history of one of the following:

• Treatment with dose intensive chemotherapy and/or radiotherapy

• Previous history of allo/auto transplant

• History of multiple myeloma or extramedullary plasmacytoma

• Chronic disease or co-morbid medical condition including subjects with symptoms or signs of significant pulmonary disease, hepatic disease, kidney disease, cardiac disease or disease of other organ systems which would result in increased risk of morbidity or death from a standard myeloablative transplant.

Diseases to be included:

• CML chronic phase

• Acute lymphoblastic leukemia (ALL), all subjects in complete or partial remission.

• AML: AML in first complete or partial remission Exceptions: AML with good risk karyotypes: AML M3 t(15:17), AML M4Eo (inv. 16), AML t(8;21). All AML in second or subsequent complete remission.

• MDS: refractory anemia with excess blasts (RAEB), or chronic myelomonocyte leukemia (CMML).

• Myeloproliferative diseases associated with either cytopenia or uncontrolled proliferation.

• CLL or small lymphocytic lymphoma (SLL) with bulky or progressive disease despite prior treatment with chemotherapy which includes purine analogs.

• NHL

A) Intermediate or high grade relapsed or progressive despite treatment with standard therapy ineligible for autologous PBSC transplant.

B) NHL intermediate or high grade relapsing despite prior autologous transplant.

C) Low grade follicular or small lymphocytic lymphoma (1) high risk patients who have relapsed following conventional chemotherapy, (2) relapsed following autologous marrow or PBSC transplant, or (3) chemo resistant disease.

D) Mantle cell lymphoma

E) NHL intermediate or high grade with concurrent BCL2 and MYC translocations who are at high risk for relapsed and who have low survival with conventional chemotherapy.

• HD, relapsed after prior autologous transplant or after 2 or more combination chemotherapy regimens and ineligible for autologous PBSC transplant.

• EBV driven lymphoproliferative disorders progressing despite standard therapies.

• MM: MM subjects must be between the ages of 8 and 65 (both inclusive)

• Mycosis fungoides, which has been shown to be amenable to allogeneic stem cell transplants.

Group B: (Closed to enrollment Oct 2010) Subjects with hematologic diseases associated with reasonable longevity, shown to be curable by allogeneic BMT but where concern for a high procedural mortality with conventional BMT may delay or prevent such treatment.

Ages 8 to 80 (both inclusive) with a history of one of the following

• PNH associated with either life-threatening thrombosis, cytopenia, transfusion dependence or recurrent and debilitating hemolytic crisis.

• Aplastic anemia or PRCA (acquired or congenital) in subjects associated with transfusion dependence and/or neutropenia who are not candidates for or who have failed immunosuppressive therapy

• RA or RARS MDS subjects who have associated transfusion dependence and/or neutropenia.
