What You Need to Know Before You Apply

What is the purpose of this trial?

This is a research study testing a new approach to treating high-risk non-Hodgkin's lymphoma consisting of an autologous hematopoietic (blood) stem cell transplant (using a patient's own hematopoietic cells) followed by a non-myeloablative allogeneic transplantation (transplant from another individual). The investigators hypothesize that the addition of the second non-myeloablative transplant will improve the chances for long-term control of lymphoma.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is stem cell transplantation generally safe for humans?

Stem cell transplantation, particularly autologous (using the patient's own cells), is considered relatively safe with advances in supportive care, showing a mortality rate mainly less than 5%. However, there is a risk of relapse after transplantation, and safety can vary depending on the patient's prior treatments and condition. ^{1 2 3 4 5}

How is autologous hematopoietic stem cell transplantation different from other treatments for non-Hodgkin's lymphoma?

Autologous hematopoietic stem cell transplantation is unique because it uses a patient's own stem cells to help recover from high-dose chemotherapy, which can be more effective than conventional chemotherapy for high-risk or relapsed non-Hodgkin's lymphoma. ^{2 6 7 8 9}

What data supports the effectiveness of the treatment for Non-Hodgkin's Lymphoma?

Research shows that autologous stem cell transplantation can lead to long-term survival and disease-free survival in patients with relapsed T-cell and B-cell non-Hodgkin's lymphoma. In one study, the 2-year disease-free survival was 28% for T-cell and 17% for B-cell patients, indicating that this treatment can be effective for some patients. ^{1 2 7 10 11}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-70 with high-risk non-Hodgkin's lymphoma who've had a stem cell transplant using their own cells. They must be in partial remission, have a matched donor ready, and agree to birth control. Excluded are those with prior radioimmunotherapy, progressive disease post-transplant, HIV-positive individuals or other recent cancers.

Inclusion Criteria

My blood counts are stable after a stem cell transplant, and I have a suitable donor.

Serum bilirubin < or = 2 x the institutional ULN

Patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines

Exclusion Criteria

Pregnant or breast-feeding women

I have had cancer before, but I've been cancer-free for 5 years, except for certain skin cancers or in situ cervical cancer.

I have had a stem cell transplant more than 120 days ago or never had one.

What Are the Treatments Tested in This Trial?

Interventions

• Autologous Hematopoietic Stem Cell Transplantation
• Non-myeloablative Allogeneic Transplantation

Trial Overview The study tests if adding a second stem cell transplant from another person after an initial self-donated transplant can better control lymphoma. It involves drugs like Anti-thymocyte globulin and Tacrolimus to help the body accept the new cells.

How Is the Trial Designed?

Group I: Allogeneic Transplant Experimental Treatment 6 Interventions

* TLI - 80 cGy on days -14, -11, -10, -9, -8, -7, -4, -3, -2, -1 * Anti-thymocyte globulin (ATG) 1.5 mg/kg on days -11, -10, -8, -7 * Solumedrol - 1 mg/kg on days -11, -10, -9, -8, -7 * Tacrolimus - beginning on day -3 with starting dose of 0.3 mg/kg PO BID. Will be continued per institutional guidelines. * Stem cell infusion - day 0 * Mycophenolate mofetil (MMF) - beginning on day 0 with dose of 15 mg/kg PO (5-10 hours after transplant)
