There is new hope for the treatment of chemotherapy-resistant malignant melanoma. Novel assay finds that widely prescribed anti-parasite drug targets cancer-causing protein.

Researchers at the NYU Cancer Institute and the Ronald O. Perelman Department of Dermatology have identified mebendazole, a drug used globally to treat parasitic infections, as a novel investigational agent for the treatment of chemotherapy-resistant malignant melanoma.

Because most patients with metastatic melanoma fail to respond to available therapies, the discovery of a viable investigational treatment with an established safety profile could address a serious unmet need in oncology. Effectively sidestepping the prohibitive costs and long lead times typically required to discover new cancer medicines, the NYU team screened a library of already approved drugs for activity against the most deadly form of skin cancer.

Their report, which was selected for advance online publication by Molecular Cancer Research, is published in the August issue of the journal. Since submitting the article for publication, the authors have conducted additional pre-clinical studies of mebendazole in an in vivo model of chemotherapy-resistant melanoma and are now preparing a phase I clinical trial, expected to begin next year at NYU Cancer Institute.

"While rational drug design remains a perfectly valid way to develop cancer therapies, we also need approaches that are less costly and more productive of new effective treatments," said lead author Seth J. Orlow, M.D. Ph.D., Chair of the Ronald O. Perelman Department of Dermatology at New York University School of Medicine. "You could say this is more of a guerrilla approach. Instead of screening millions of untested compounds for an agent that inhibits or stimulates a particular molecular target, we chose to screen a large library of already approved drugs for novel activity against melanoma cells, and then advance the most promising candidate rapidly to clinical practice."

Here is a quote from the last page I read concerning mebendazole. " Epilogue: Discontinuation in United States The last manufacturer of mebendazole in the United States, Teva Pharmaceuticals, announced on October 7, 2011, that they have ceased manufacture of this product. As of December, 2011, it is no longer available from any manufacturer in the USA. No reason was given for this discontinuation, but it's blatantly obvious."
