Detailed Summary

The purpose of this study is to test whether giving acalabrutinib is safe and effective in controlling relapsed central nervous system (CNS) lymphoma. Currently, there are no FDA-approved treatments for relapsed CNS lymphoma. Although acalabrutinib has not been approved for the treatment of CNS lymphoma, it was approved for the treatment of another type of lymphoma (mantle cell), by the Food and Drug Administration (FDA). Acalabrutinib acts similar to another cancer drug called ibrutinib. lbrutinib was tested in several research trials for the management of CNS lymphomas, and the results were promising. Acalabrutinib and ibrutinib attack a similar target found in CNS lymphoma. Acalabrutinib may do a better job in attacking this target than ibrutinib. The study doctors will be looking to see if acalabrutinib can shrink cancer cells.

Arms & Interventions

Open-label, single-armother

A multicenter open-label, single-arm, phase 2 study designed to investigate the antitumor effects of acalabrutinib in subjects with relapsed primary central nervous system lymphoma (PCNSL), and relapsed secondary CNS lymphoma (SCNSL) with no evidence of current systemic disease. Subjects will receive acalabrutinib at the dose of 100 mg every 12 hours.

Drug: Acalabrutinib

Interventions

Acalabrutinibdrug

Acalabrutinib at 100 mg is taken orally approximately every 12 hours until disease progression or unacceptable toxicity.
