What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to find out what effects (good and/or bad) treatment with chemotherapy and stem cell transplant compared with chemotherapy alone will have on primary CNS B-cell lymphoma. Currently the best treatment for patients with primary CNS B-cell lymphoma is not known.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, since the trial involves chemotherapy and stem cell transplant, it's best to discuss your current medications with the trial team to ensure there are no interactions.

Is the chemotherapy and stem cell transplant treatment generally safe for humans?

The treatment involving chemotherapy and autologous stem cell transplant has been studied for safety. In one study, replacing carmustine with thiotepa and cyclophosphamide showed similar safety profiles, even in older patients. However, high-dose regimens can lead to serious side effects like lung disease and infections, with a 20% early death rate due to toxic effects in some cases.12345

How does the chemotherapy drug combination of Carmustine, Cytarabine, and Thiotepa differ from other treatments for lymphoma?

This treatment is unique because it combines high-dose chemotherapy drugs with a stem cell transplant, aiming to aggressively target lymphoma cells. Unlike some other regimens, it includes Thiotepa, which is less commonly used in standard protocols, potentially offering a different mechanism of action or side effect profile.56789

What data supports the effectiveness of the treatment Autologous Stem Cell Transplant with Carmustine, Cytarabine, and Thiotepa for Lymphoma?

Research shows that thiotepa-based conditioning regimens, which include drugs like carmustine and cytarabine, have comparable effectiveness and safety to traditional regimens in treating lymphomas, even in older patients. This suggests that the combination used in the trial could be effective for lymphoma treatment.123510

Published Research Related to This Trial

In a retrospective study of 56 patients with primary central nervous system lymphoma (PCNSL) undergoing autologous stem cell transplant (ASCT), there was no significant difference in progression-free survival or overall survival between those receiving thiotepa-based conditioning and those receiving BEAM conditioning, despite the thiotepa group having higher-risk disease features.
The study found that the disease response status before transplant was a critical factor influencing outcomes, with patients in complete remission showing significantly better overall survival rates compared to those with partial response, highlighting the importance of pre-transplant disease status.

The TECAM conditioning regimen, which includes thiotepa and cyclophosphamide, showed comparable efficacy and safety to the conventional BEAM regimen in a study of 125 patients undergoing autologous stem cell transplantation for B-cell lymphomas, with 3-year progression-free survival rates of 49% for TECAM and 62% for BEAM.
TECAM was particularly effective for older patients, with 23% of TECAM recipients over 65 years old achieving similar outcomes to younger patients, suggesting it may be a suitable option for older individuals who have had more prior treatments.

In a phase I study involving 40 patients with refractory solid tumors or non-Hodgkin's lymphoma, a combination of high-dose cyclophosphamide, thiotepa, and carmustine (BCNU) followed by autologous stem cell rescue resulted in a 63% overall response rate, indicating significant efficacy in reducing tumor burden.
However, the treatment was associated with serious safety concerns, including a 20% early death rate due to toxic effects like sepsis and respiratory failure, particularly at higher doses of BCNU, which limits its use in heavily pretreated patients.
