This page summarizes the current state of scientific research on Niclosamide in the context of Breast Cancer as of 2026. The field evolves rapidly — this is a research summary, not medical advice. Consult your oncologist for personalized guidance.

Compound Overview

Niclosamide (Antiparasitic / Salicylamide) — FDA-approved for intestinal tapeworm; not approved for cancer

Mechanism of action: Inhibits Wnt/β-catenin, Notch, mTOR, STAT3, and NF-κB signaling; uncouples mitochondrial OXPHOS

Current evidence level: Preclinical + Phase I trials; bioavailability challenges being addressed
