Time frame
Assessments every 8 weeks from study day 1 for the first 24 weeks, and then every 12 weeks until disease progression, death, or initiation of subsequent treatment. Total follow-up was up to approximately 3 years.

What was measured

A secondary efficacy endpoint is DOR as assessed by the investigator. The DOR is defined as the time from the date that a confirmed response per modified RECIST Version 1.1/PCWG3 is first reported to the time that progressive disease (PD) is first documented. Progressive disease is defined using RECIST v1.1, as at least a 20% increase in the sum of the diameters of target lesions, or an unequivocal increase in non-target lesions, or the appearance of new lesions. PCWG3 criteria is used to document evidence of disease progression in bone lesions.

Analysis population: Patients with a confirmed response in the Investigator Efficacy Population. The Investigator efficacy population is defined by measurable disease status at baseline using modified RECIST Version 1.1 criteria per the investigator. Note, there were no patients with confirmed response by investigator in the CDK12 arm.

Groups in this outcome
