Real-World Clinical Outcomes of Ivermectin and Mebendazole in Cancer Patients: Results from a Prospective Observational Cohort (medical study)

A new observational study of 197 cancer patients taking a combined ivermectin + mebendazole protocol is going viral on social media — and for understandable reasons. At six-month follow-up, 84.4% of respondents reported clinical benefit (no evidence of disease, regression, or stable disease), and nearly half (48.4%) reported either tumor regression or no current evidence of disease. The combination was well tolerated, with only mild, mostly gastrointestinal side effects. The paper, posted on Zenodo about a week and a half ago, is the largest structured real-world look at this specific repurposed-drug pairing published to date.

This post is a summary. The full study is here: https://zenodo.org/records/19455636

The study was led by Nicolas Hulscher, MPH of the McCullough Foundation, with co-authors including Peter A. McCullough, MD, MPH, Harvey Risch, MD, PhD of the Yale School of Public Health, and Dr. Drew Pinsky — names many readers will recognize from the COVID era. That matters because it tells you where the paper sits: this is the same network of physicians and researchers that pushed early on repurposed-drug approaches during the pandemic, now turning the same lens on oncology.

The cohort skewed older (mean age 67) and covered prostate, breast, lung, colon, pancreatic, liver, and several other cancers. Patients took compounded capsules containing 25 mg ivermectin and 250 mg mebendazole, typically 1–2 per day. Adherence was high: 86.9% finished the initial 90-capsule course and 66.4% were still on protocol at six months. Many patients were also receiving standard care — chemotherapy (27.9%), radiation (21.3%), or surgery (19.7%) — alongside supplements and dietary changes.

The authors are clear about the caveats: outcomes were self-reported, there was no control group, all authors are affiliated with The Wellness Company (which prescribes, dispenses, and sells the protocol via telemedicine to all 50 states), and the paper is a preprint, not peer-reviewed. They describe the findings as "hypothesis-generating" and call for randomized, placebo-controlled trials.

Still, the signal is large enough, and the drugs cheap and safe enough, that it's worth reading the original rather than relying on social-media takes. Link above.

Shame Trump endorsed Ivermectin, it was the kiss of death for a lot of research.

Dunno if you are spun up on this or not. There is an active effort by Big Pharma and paid off doctors to demonize and ban the use of ivermectin. Alberta outlawed it outright.

A lot of corruption going on.

“Ivermectin is now a “horse paste”? And mebendazole a “dog wormer”?
Either you are trolling, or you are very dumb.”

The poster is correct, YOU are wrong.

“I am taking ivermectin + fenbendazole to treat stage 4 pancreatic cancer in conjunction with chemotherapy. It works.”

It’s nice to hear that, thank you for the good news.
Do you mean the cancer is stable or has reduced?
A collegue’s good friend had this too. Was given 6 to 12 months considering he hadn’t comorbidities. He was being treated by conventional chemo as outpatient for 2 weeks. Of course, his doctors never mentionned Ivermectin or Fenben or fasting. They called him back urgently to the hospital because his liver numbers were becoming alarmingly bad. He passed away a week later.
We think he was killed the treatment, not by the disease.

The cancer has both stabilized and reduced. Condolences on your feiend’s passing.

"Still, the signal is large enough ..."

Since there was no control group, what was "the signal"?

The purpose of the control group is to measure the signal by comparing the outcomes and having a large enough population to reduce the effects of uncontrolled variables.

What are we to assume about "the signal"?

Not trolling, my FRiends. Ivermectin is the "horse paste" and Mebendazole (or rather, the original Fenbendazole) is the "dog wormer" you've heard mentioned. And some of us conspiracy theorist types have been advocating and using these to treat cancer, with the addition of Artemisinin, for closing in on a decade now. And, with great success! (Change your diet too -- lots of greens, nothing processed, and cut the sugars and carbs.)

In an attempt to preserve the precious "covid vaccines are safe and effective" tripe we took a lot of heat from a lot of morons. But it was a light burden because we have personally witnessed lives being saved. I don't take any credit; that belongs to the Good Lord and the pioneers like Joe Tippens. But I will say it is mighty rewarding to have a friend walk into your office and literally thank you for saving his life just for opening your big mouth and being willing to repeat aloud what you've seen and heard at a time when Big Pharma and Big Media have put on a full-court press to shut you up.

I know people who have eliminated their cancers, some having skipped chemotherapy and radiation and their side effects entirely. This is my reality; these are my facts. So it doesn't much matter what people think of me. I'll keep opening my big mouth. And I pray better health for all my FRiends.

Thanks for the Ping!
