The purpose of this study is to determine the efficacy of BRain-AVOidant proton craniospinal irradiation (BRAVO pCSI) in adult participants with leptomeningeal metastases from solid tumors.
Inclusion Criteria: 1. Participants with leptomeningeal metastases established radiographically and/or through Cerebrospinal Fluid (CSF) cytology or circulating tumor cells (CTCs). Participants may have newly diagnosed or recurrent LM. 2. Pathologically confirmed breast or non-small cell lung cancer (NSCLC) primary (group 1 and). Pathologically confirmed solid tumor malignancy (group 2). 3. Participants with adequate bone marrow function. 4. Participants with a Karnofsky Performance Status (KPS) ≥ 60. 5. Male and female participants ages ≥ 18 years. 6. Female participants must be of either no…
Participants with Leptomeningeal Metastases (LM) from breast or non-small cell lung cancer will be included in Group 1 (20 evaluable participants). Participants with LM from solid tumors of other histologies will be included in Group 2 (10 evaluable participants). All participants in Groups 1 and 2 will receive Brain-Avoidant Proton Craniospinal Irradiation (BRAVO-pCSI) at a prescribed dose of 30 Gy (Cobalt Gray Equivalent \[CGE\]) delivered in 10 fractions. Protocol treatment must begin within 21 days of study enrollment and will be delivered over approximately 2 weeks.
