Trial Outcomes & Findings for Oral Tamoxifen vs. TamGel vs. Control in Women With Atypical Hyperplasia, Lobular Carcinoma In Situ, or Increased Breast Cancer Risk (NCT NCT04570956)

NCT ID: NCT04570956

Last Updated: 2026-09-01

Results Overview

All patients received an oral pill and a topical gel. Prior to assessing non-inferiority of 4-OHT Gel compared to Oral Tamoxifen, treatment effect was assessed within each group by testing for a significant reduction in median lobular Ki67 between PreTam and OnTam biopsy. Median lobular Ki67 is assessed using the percentage of cells stained across all lobules separately at PreTam and OnTam timepoints, evaluated for a difference in median calculated change.

PRIMARY outcome

Timeframe: Pre-biopsy to post-biopsy following 4 weeks of intervention

Population: Of the 61 patients who initiated study intervention, two withdrew during intervention and one tested positive for COVID (unable to complete the post-treatment research core biopsy). Among the remaining 58 subjects, 48 had breast tissue successfully obtained at both the pre-treatment and post-treatment timepoints for the primary endpoint. Of these 48 patients, only 42 had sufficient breast lobules seen histologically for evaluation of the primary endpoint (change in median lobular Ki67).

All patients received an oral pill and a topical gel. Prior to assessing non-inferiority of 4-OHT Gel compared to Oral Tamoxifen, treatment effect was assessed within each group by testing for a significant reduction in median lobular Ki67 between PreTam and OnTam biopsy. Median lobular Ki67 is assessed using the percentage of cells stained across all lobules separately at PreTam and OnTam timepoints, evaluated for a difference in median calculated change.
