Study Description

Brief Summary:

Primary central nervous system lymphomas are rare aggressive malignancies, usually treated in two steps: an induction phase (where a combination of chemotherapy is given) followed by a consolidation phase (where patients usually receive one of the following: whole-brain irradiation, chemotherapy supported by autologous stem-cell transplantation, other type of chemotherapy, or are just observed).

The feasibility of this overall strategy, for several reasons, is limited in elderly patients .

This study involves patients aged ≥70 years. The more fit patients will receive the standard chemotherapy combination (high-dose methotrexate, procarbazine and rituximab) as induction. Responding patients will receive either procarbazine or lenalidomide as maintenance therapy; the aim is to evaluate the efficacy of these two drugs.

The more fragile patients will receive a less aggressive therapy consisting of concomitant whole-brain radiotherapy, temozolomide and rituximab as induction therapy, followed by temozolomide as maintenance treatment; the aim is to evaluate the efficacy of this combination of treatment.

Detailed Description:

Primary central nervous system lymphomas (PCNSL) are rare aggressive malignancies, mostly of B-cell origin, representing 4% of intracranial neoplasms and 4-6% of extranodal non-Hodgkin's lymphomas (NHL). Despite improvements in treatment, PCNSL is associated with an aggressive course and unsatisfactory outcome. The median age at diagnosis is 61 years and age over 60 years has been reported to be an independent factor for a poorer outcome.

The modern treatment of PCNSL includes two phases: induction and consolidation. The induction phase usually consists of a polychemotherapy combination, including high-dose methotrexate as a critical drug, while there are at least four different strategies that can be used as consolidation: whole-brain irradiation, myeloblative chemotherapy supported by autologous stem-cell transplantation, non-myeloblative chemotherapy, observation (only in patients who achieve complete remission after induction).

The feasibility of this overall strategy is limited, for several reasons, in elderly patients with newly diagnosed PCNSL. High-doses of antimetabolite-based chemotherapy, the standard induction for patients younger than 70 years, is often not feasible in elderly patients. Among maintenance strategies, simple observation results in unacceptably high relapse rate and associated mortality while whole-brain irradiation and aggressive chemotherapies are associated with unacceptable toxicity and poor outcome. Thus, new strategies aimed at obtaining durable responses with an acceptable tolerability and reduced risk of neurocognitive decline are needed and these strategies should be tailored not only based on the patients' age but also on their specific co-morbidities and general health conditions.

For the present trial, all patients aged ≥70 years taken into care at the participating sites will be invited to participate and after informed consent signature their baseline data will be collected in the trial database, including data of patients resulting in screening failure. This will allow to verify any potential screening bias by comparing the characteristics of included and excluded patients. Patients fulfilling the eligibility criteria are then screened for their suitability to receive a more or less aggressive anticancer treatment and assigned to two different treatment strategies accordingly.

Part A:

The more fit patients are assigned to the trial Part A and will receive the standard combination of high-dose methotrexate, procarbazine and rituximab as induction. Responding patients will subsequently be randomized to receive either procarbazine or lenalidomide as maintenance therapy.

Procarbazine is a lipophilic oral alkylating agent, easily crossing the blood brain barrier (up to 100% of plasma levels). There is no known cumulative toxicity for procarbazine and it is therefore currently in use as a viable maintenance treatment option aimed at eliminating residual lymphoma cells in the CNS and reduce the risk of relapse. Lenalidomide is an oral immunomodulatory agent, active against diffuse large B cell lymphoma, the most common category in PCNSL, which can be taken for years, showing an excellent safety profile. On this background, the Part A of the present trial consists of a randomized phase II trial conducted in elderly patients with newly diagnosed PCNSL responsive to high-dose methotrexate-based chemotherapy, comparing two different maintenance strategies: the oral chemotherapeutic drug procarbazine and the oral immunomodulatory agent lenalidomide.

Part B:

The more fragile patients are assigned to the trial Part B and will receive a less aggressive therapy consisting of concomitant whole-brain radiotherapy, temozolomide and rituximab as induction therapy, followed by temozolomide single-agent as maintenance treatment.

Whole-brain radiotherapy is the main therapeutic choice for patients with contraindications to chemotherapy and in particular for elderly patients. Brain irradiation is usually associated with transient disruption of the blood-tumor barrier, occurring from 1 week after the initiation of radiotherapy to 1 month after its completion, during which pharmaceutical agents have maximum access to tumor tissue. Concomitant delivery of active cytostatics, therefore, could result in increased tumor uptake. Concomitant delivery of radiotherapy and temozolomide is currently used as standard approach for the treatment of high-grade gliomas, with acceptable toxicity despite the use of a larger irradiation dose. Based on the above, in the Part B of the present trial, temozolomide and rituximab, two agents active against PCNSL, are delivered concomitantly to whole-brain radiotherapy to obtain a synergistic effect of radiation damage, antineoplastic effect of rituximab and cytostatic and radiomimetic effects of temozolomide. Finally, temozolomide maintenance has shown to be beneficial regarding sustained remission after initial response to induction therapy and its suitability to improve disease control in responding patients not fit for more aggressive therapies will therefore be tested in the Part B of this trial.

Study Design

• Study Type: Interventional (Clinical Trial)
• Estimated Enrollment: 208 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment

Intervention Model Description

Multicenter open label phase II trial. The patients will be stratified according to their suitability to tolerate an induction chemo-immunotherapy regimen containing high-dose methotrexate.

Patients eligible for high-dose methotrexate-based induction chemotherapy will enter the run-in phase of Part A of the study and after the induction phase will be randomly assigned to procarbazine or lenalidomide maintenance monotherapy. Forty assessable patients per treatment arm are required.

Patients ineligible for high-dose methotrexate-based induction chemotherapy will be treated în Part B with concomitant whole-brain radiotherapy, temozolomide and rituximab and will receive temozolomide as maintenance.According to the Simon's two-stage minimax design, 46 patients will be treated in the first stage. If ≤ 16 patients will be progression-free at 2 years from maintenance treatment start, the study will be stopped. Otherwise, 19 additional patients will be treated for a total of 65

Outcome Measures

Primary Outcome Measures :

1. Two years Progression Free Survival (PFS) - part A [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years. ]

2. Response Rates (part B) [ Time Frame: From the start of the treatment until disease progression, assessed up to 2 years from start of maintenance. ]
   Proportion of patients showing CR, PR, SD, PD as best response to treatment
3. Overall survival (OS) [ Time Frame: From date of induction treatment start until the date of death from any cause or the date of the last visit in patients still alive at study end, assessed up to 2 years from start of maintenance. ]
