Prospective study of 197 cancer patients reports 84.4% clinical benefit rate with ivermectin and mebendazole combination
By
NICOLAS HULSCHER
Summary
This prospective observational cohort study analyzed 197 cancer patients prescribed a combination of ivermectin and mebendazole off-label via a U.S. telemedicine platform. At six-month follow-up (122 participants completed), the study reported a Clinical Benefit Ratio of 84.4%, with 48.4% of participants reporting tumor regression or no evidence of disease, 36.1% stable disease, and 15.6% progression. Adherence was high (86.9% completed initial prescription), side effects were predominantly mild and gastrointestinal (25.4% reported), and 93.6% continued therapy after dose adjustment. The authors conclude the findings are hypothesis-generating and support the need for randomized controlled trials.

At follow-up, 48.4% of participants reported tumor regression or no evidence of disease (32.8% NED; 15.6% regression), while 36.1% reported stable disease and 15.6% reported progression.
Side effects, reported by 25.4%, were dose-dependent and predominantly mild and primarily gastrointestinal, with 93.6% continuing therapy after adjustment.
These findings are hypothesis-generating and support the need for randomized controlled trials.
