A Pilot Study Incorporating Motexafin Gadolinium (MGd) Into High-dose Methotrexate (MTX)-Based Chemo-immunotherapy and Radiation for Patients With Newly Diagnosed Primary CNS Lymphoma
- Determine the safety and efficacy of motexafin gadolinium (MGd) combined with high-dose
methotrexate-based chemotherapy and radiotherapy in patients with newly diagnosed
primary CNS lymphoma.
- Determine the toxicity of MGd and rituximab combined with high-dose methotrexate,
procarbazine hydrochloride, and vincristine (MPV) in these patients.
- Determine the toxicity of MGd in combination with whole-brain radiotherapy (WBRT) in
- Determine the tumor-selective uptake of MGd.
- Determine the overall response rate (complete remission [CR] and partial remission
[PR]) in patients treated with pre-radiotherapy and chemo-immunotherapy (R-MPV with
- Determine the complete response rate in patients treated with this regimen.
- Determine the overall response rate (CR and PR) in patients who complete all MGd
combined with high-dose methotrexate-based chemotherapy and WBRT.
- Determine the event-free and overall survival at 1 year of patients treated with this
- Determine the progression-free survival at 1 year of patients treated with this
- Evaluate the neurotoxicity of R-MVP with MGd based on pre- and post-treatment
- Tumor-selective imaging: Patients receive motexafin gadolinium (MGd) IV on days 1-2
beginning 1-2 weeks prior to induction therapy. They then undergo an MRI of the brain.
- Induction therapy: Patients receive methotrexate IV over 2-3 hours and vincristine IV
on day 1 and rituximab IV over 5 hours and MGd IV over 30-60 minutes on day 8. Patients
also receive oral procarbazine hydrochloride on days 1-7 of courses 1, 3, and 5.
Treatment repeats every 14 days for 5 courses in the absence of disease progression or
unacceptable toxicity. Patients with partial response receive an additional 2 courses
of induction therapy.
- Chemoradiotherapy: Beginning 4 weeks after completion of induction therapy, patients
undergo reduced-dose whole-brain radiotherapy for 6 weeks. Patients also receive MGd IV
over 30-60 minutes, beginning 2-5 hours prior to radiotherapy, for 10 days and then
every other day during radiotherapy.
- Consolidation therapy: After completion of chemoradiotherapy, patients receive
cytarabine IV over 3 hours on days 1-2. Treatment repeats every 30 days for 2 courses.
After completion of study therapy, patients are followed every 3 months for the first year,
every 3-4 months for the second year, every 4-6 months until the fifth year, and then
Allocation: Non-Randomized, Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Toxicity of motexafin gadolinium (MGd) and rituximab added to high-dose methotrexate, procarbazine hydrochloride, and vincristine (MPV) chemotherapy
