Trial Outcomes & Findings for Avatar-Directed Chemotherapy in Treating Patients With Ovarian, Primary Peritoneal, or Fallopian Tube Cancer (NCT NCT02312245)

NCT ID: NCT02312245

Last Updated: 2024-12-05

Results Overview

Estimated by the number of successes divided by the total number of evaluable patients. Ninety-five percent confidence intervals for the true success proportion will be calculated according to the exact Binomial method. The primary analysis will pool across all patients, and tumor response rate by treatment arm will also be looked at in an exploratory fashion.
