TAMENDOX (NCT03931928) · Breast Cancer, DCIS
The completed lead evidence is positive, with design limits that temper confidence; the rationale below says which.
TAMENDOX (NCT03931928): This was a randomized, participant-masked, placebo-controlled study of 356 patients, but its primary endpoint was a pharmacokinetic concentration threshold rather than a clinical or endoscopic outcome. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.
