Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Determine the change in the number of regimen limiting toxicities (RLT) in the experimental cohort
Document the change in the number and severity of CTCAE adverse events that are probably or definitely related to study treatment (tadalafil or influenza) in the experimental cohort.
Secondary outcome measures
Compare the reduction in Natural Killer cell killing as measured on PBMC collected on SD1 as compared to baseline between the control and experimental cohorts, using a standard Natural Killer cell killing assay (51Chromium release assay).
