Participant Flow

In total, 122 patients were randomized. Two patients withdrew due to an inadequate number of biopsies and a finding of high-grade dysplasia. Six participants were not evaluable for the primary endpoint due to sample-related issues (e.g., improper temperature, lost or delayed samples), leaving 114 evaluable participants for the primary endpoint.

Of the 120 participants in the intervention cohort, 114 were evaluable for the primary endpoint (n = 29, 42, and 43 in Arm I, Arm II, and Arm III, respectively).

SECONDARY outcome

Timeframe: Up to 30 days after completion of study treatment

Population: All 120 patients that took study medication were evaluable for this secondary endpoint.

Toxicity is defined as adverse events that are classified as either possibly, probably, or definitely related to the interventional agent, graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. The number of patients reporting adverse events will be tabulated by grade.
