What was measured

Progression-free survival (PFS) is defined from the date of initiating study treatment to the date of disease progression per the International Primary CNS Lymphoma Collaborative Group response assessment criteria or death as a result of any cause. Categories included complete response (no evidence of disease), partial response (reduction in disease burden), stable disease (no significant change), and progressive disease (disease worsening), based on radiographic findings, corticosteroid use, and clinical status.

Groups in this outcome

Open-label, Single-arm

Subjects with relapsed primary central nervous system lymphoma (PCNSL) or relapsed secondary CNS lymphoma (SCNSL) without systemic disease will receive acalabrutinib until disease progression or unacceptable toxicity.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
