Time frame
Assessed at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

What was measured

PFS was defined as time from treatment start date to date of disease progression or death from any causes, whichever occurred first. Median PFS was estimated using the Kaplan-Meier method. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression.

Analysis population: Patients who were eligible and received protocol treatment

Groups in this outcome

Treatment (Afatinib Dimaleate)

Patients receive afatinib dimaleate 40mg PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Afatinib Dimaleate: Given PO
