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-intervention

Population: 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.
