What this Trial Is About

Most patients being diagnosed with primary diffuse large B-cell lymphoma of the central nervous system (PCNSL) are 60 years or older. Elderly patients with PCNSL have a poor prognosis and there is a great medical need to improve outcome for this vulnerable population. In Germany and many international centres, there are currently two widely used strategies to treat elderly PCNSL patients who are eligible for high-dose methotrexate (HD-MTX) treatment, which have not yet been compared head-to-head. The R-MP regimen has been established by the Cooperative PCNSL Study Group as a "conventional" immunochemotherapy standard treatment for elderly patients with newly diagnosed disease and consists of Rituximab, HD-MTX and Procarbazine followed by maintenance therapy with Procarbazine. In contrast, another recently established protocol also includes HD-MTX-based induction therapy, but followed by consolidating high-dose chemotherapy and autologous stem cell transplantation (HCT-ASCT). This is an overall more intensive, but substantially shorter treatment approach, feasible for elderly patients being considered eligible for a more intensive treatment. The PRIMA-CNS trial aims to compare these two treatment approaches with respect to survival, response rates and toxicity.

Eligibility Criteria

Eligible

You may qualify if you...

  • Immunocompetent patients with newly diagnosed primary diffuse large B-cell lymphoma of the central nervous system.
  • Age over 70 years, or age 65 to 70 years if not eligible for more intensive treatment.
  • Diagnosis confirmed by histology or cytology by a local pathologist.
  • Diagnostic sample obtained by biopsy, cerebrospinal fluid examination, or vitrectomy.
  • Disease limited exclusively to the central nervous system.
  • At least one measurable lesion present.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 2 or less; higher scores accepted if due to PCNSL symptoms.
  • Patients considered potentially eligible for high-dose chemotherapy and autologous stem cell transplantation as judged by the treating physician.
  • Written informed consent obtained from the patient or legal representative if patient is temporarily not competent.
  • No evidence of disease progression after pre-phase treatment.
