Use of Optune TTF With Radiation as an Alternative for Elderly Patients With Primary CNS Lymphoma

Study Purpose

This study will compare the overall survival (OS) time of elderly patients who would not tolerate standard chemotherapy for PCNSL treated with WBXRT together with Optune-TTF to those treated with whole-brain radiotherapy alone. Standard treatment of primary central nervous system lymphoma (PCNSL) for patients with good performance status involves high-dose methotrexate-based chemotherapy regimens and whole-brain radiation therapy (WBXRT). Although up to 20% of patients with PCNSL are 80 years of age or older, little data exist with regard to optimal treatment of this patient population and they often do not qualify for clinical trials. In addition, elderly patients have a poorer rate of complete and partial response and increased risk of toxicity when treated with standard chemotherapy regimens. Though a consensus does not exist, radiotherapy alone is often used in these patients to minimize toxic effects of more aggressive chemotherapies. The Optune TTF device has proven effective in treating high-grade gliomas and is currently being investigated to treat meningiomas and metastatic lesions in the brain as well as other tumor types elsewhere in the body. It is generally well tolerated with no known systemic side effects, producing only an occasional local skin reaction. The mechanism of action is independent of tumor type and therefore may be effective in treating lymphoma as well.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
