Trial Outcomes & Findings for Enzalutamide for Patients With Androgen Receptor Positive Salivary Cancers (NCT NCT02749903)

NCT ID: NCT02749903

Last Updated: 2021-10-26

Results Overview

The best overall response rate (percentage) is the percent of patients whose best response was Complete Response (CR) or Partial Response (PR) as defined by RECIST 1.1 criteria. Percentage of successes will be estimated by 100 times the number of successes divided by the total number of evaluable patients.

Measure
Enzalutamide
Patients receive 160 mg enzalutamide orally once daily (1 cycle=28 days). Patients will remain on therapy until progression of disease or development of unacceptable toxicities or patient or physician withdrawal. Patients will undergo radiographic imaging every 2 months while on study treatment in order to determine response.

SECONDARY outcome

Timeframe: Up to 32 months post study enrollment

Progression free survival (PFS) is defined as the time from the date of randomization to the date of disease progression or death resulting from any cause, whichever comes first. Progression is defined according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator. Progression is defined according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
