Trial Outcomes & Findings for A Trial of Tadalafil in Patients With Squamous Cell Carcinoma of the Upper Aero Digestive Tract (NCT NCT00894413)
NCT ID: NCT00894413
Last Updated: 2019-06-11
Results Overview
Median fold-change in immune response of T-cell expansion, delayed-type hypersensitivity reactions, CD4/CD69, CD8/CD69. A positive value indicates an increase in immune response.

PRIMARY outcome
Timeframe: Change from baseline to up to 14 days post-interventionPopulation: Data was not evaluable in 1/15 participants from the placebo group, 2/17 participants in the tadalafil group (for T-cell expansion, CD4/CD69, CD/CD69) and 1/17 for DTH area.
Median fold-change in immune response of T-cell expansion, delayed-type hypersensitivity reactions, CD4/CD69, CD8/CD69. A positive value indicates an increase in immune response.
