Ivermectin and mebendazole, 84% benefit in cancer (John Campbell)

Conclusions: In this prospective real-world cohort, the combination of ivermectin and mebendazole was associated with high rates of self-reported clinical benefit, with nearly half of participants reporting tumours regression or no current evidence of disease across a heterogeneous population of cancer patients.

These findings provide a compelling clinical signal that these well-tolerated, repurposed agents may offer therapeutic benefit.

However, observational design, reliance on self-reported outcomes, and potential for selection bias and uncontrolled confounding, these findings should be interpreted as hypothesis-generating.

Urgent prospective, randomized, placebo-controlled clinical trials

Validate these observations and further define optimal dosing strategies.



Very promising research.
