2023 Jun – Movahedi et al – Repurposing anti-parasite benzimidazole drugs as selective anti-cancer chemotherapeutics

  • Benzimidazole drugs (including Fenbendazole) have widely been used as anti-helminth agents in both human and/or livestock since the 1960s
  • These drugs have rapidly become more popular than previous medications due to superiority in terms of efficacy, toxicity and application
  • Benzimidazole drugs are considered as non-toxic anti-helminth agents in humans and livestock. Acute toxicities are rarely reported for these drugs.
  • Neither chronic adverse effects in dogs and rats treated with very high dosages, nor irritation, carcinogenicity or teratogenicity in treated rats and rabbits have been observed
  • Two major mechanisms of action:
  • 1. antimitotic activity (inhibition of tubulin polymerization by binding to tubulin sites of rapidly dividing cells (leads to cell cycle arrest)
  • 2. disrupt cell metabolic processes by inducing oxidative stress
  • Result: induce apoptosis (cell death) of rapidly proliferating parasites and cancer cells!
  • These drugs inhibit tumor proliferation and growth
  • many new benzimidazole derivatives have been developed for the treatment of cancers such as colon cancer, breast cancer, lung cancer, chondrosarcoma and leukemia
  • Furthermore, new benzimidazole derivatives have demonstrated high capability for overcoming drug resistance
  • benzimidazole drugs exhibit anti-metastatic effect through inhibiting cell migration and invasion
  • benzimidazole drugs also suppress telomerase reverse transcriptase (TERT) expression, whose activation is associated with metastasis
  • benzimidazole drugs are potent in targeting cancer stem cells and preventing tumor recurrence.
  • benzimidazole drugs are also found to prevent the radiation-induced transformation of cancer cells into radiation-resistant cells, and furthermore sensitize some drug-resistant cells.
  • Clinical trials are ongoing for cancer therapy with benzimidazole drugs.
  • For example, clinical study of mebendazole as adjuvant treatment for colon cancer is in Phase 3 (NCT03925662)
  • and mebendazole in combination with other antiprotozoal agents including albendazole for neoplasm therapy is in Phase 2 (NCT02366884).
  • Three Phase 1 clinical trials are also ongoing for mebendazole and brain tumors (NCT02644291, NCT01729260, NCT0183787862).
  • THERE ARE NO CLINICAL TRIALS WITH FENBENDAZOLE
  • low water solubility of benzimidazole drugs impedes their clinical applications
  • nano-formulations are being created to improve bioavailability
  • benzimidazole drugs are also being combined with other chemotherapeutics, such as paclitaxel, trametinib, gemcitabine and methoxyestradiol, to enhance the anti-cancer treatment efficacy.
  • benzimidazole drugs have also sensitized tumor cells to radiation therapy

2023 Apr – Chi-Son Chang et al – Anti-cancer effect of fenbendazole-incorporated PLGA nanoparticles in ovarian cancer

  • ovarian cancer is the deadliest gynecological cancer
  • nanoparticles deliver poorly soluble drugs
  • fenbendazole, an anti-parasitic drug was examined due to its anti-cancer effects: ability to interfere with microtubule polymerization, block cell cycle progression, increase p53 protein stability and induce apoptosis.
  • However, fenbendazole has low water solubility and poor bioavailability which are major obstacles to its clinical application as an anti-cancer agent
  • Nanoparticles were loaded with fenbendazole to increase bioavailability
  • Results: natural form of fenbendazole significantly decreased cell proliferation of both chemosensitive and chemoresistant ovarian cancer cells
  • But in vivo (xenograft mouse models), only the nanoparticle fenbendazole formulation showed anticancer effects.

2023 Mar – Semkova et al – Redox-mediated Anticancer Activity of Anti-parasitic Drug Fenbendazole in Triple-negative Breast Cancer Cells

  • fenbendazole was tested on triple negative breast cancer cells, three different types including a highly metastatic type
  • Results: the highly metastatic breast cancer cells were more vulnerable to fenbendazole induced oxidative stress

2023 Mar – Haebeen Jung et al – Differential cytotoxic effects of fenbendazole on mouse lymphoma EL-4 cells and spleen cells

  • fenbendazole was tested on a mouse lymphoma cell line vs normal spleen cells
  • purpose of this study was to investigate the cytotoxic effects of fenbendazole on normal cells of the spleen, which is a major reservoir of immune cells
  • fenbendazole increased cell death of lymphoma cells but not of normal spleen cells
  • fenbendazole induced reactive oxygen species in lymphoma cells but not normal spleen cells

2020 Aug – Deok-Soo Son et al – The Antitumor Potentials of Benzimidazole Anthelmintics as Repurposing Drugs

  • Benzimidazole anthelmintics have broad-spectrum action to remove parasites both in human and veterinary medicine
  • Due to their low cost and high efficacy, benzimidazole anthelmintics have been used throughout the world since their introduction in the 1960s
  • Benzimidazole anthelmintics are well-tolerated without severe side effects, and their decades of use provide a basis for safety in humans.
  • Benzimidazole anthelmintics selectively bind to β-tubulin of parasitic worms, causing their immobilization and death
  • In addition to being antiparasitic agents, benzimidazole anthelmintics are known to exert anticancer activities which are summarized (also see image at start of article):
  • disrupts microtubule polymerization
  • inhibits cancer cell viability
  • inhibits cancer cell migration and invasion
  • induces apoptosis and autophagy
  • increased cell cycle (G2/M) arrest
  • induces differentiation and senescence
  • inhibits angiogenesis
  • reduces colony formation and inhibits stem-ness in cancer cells
  • inhibits drug resistance and sensitize cells to conventional chemo
  • blocks glucose transport and impairs glucose utilization
  • Benzimidazole anthelmintics have been shown to inhibit cell viability in a variety of cancer cell lines, appearing as a promising medication:
  • breast cancer
  • leukemia
  • glioma & glioblastoma
  • lung cancer
  • hepatocellular carcinoma
  • rhabdomyosarcoma
  • medulloblastoma
  • urothelial cancer

  • Fenbendazole is known to have a high safety margin and most species tolerate it very well
  • Fenbendazole targets microtubules in human NSCLC Lung cancer cells
  • Fenbendazole treatment results in early G2/M block accompanied by cell death
  • Tumour cell lines with wild-type p53 show enhanced sensitivity to Fenbendazole induced apoptosis

  • Conclusion: Altogether, our findings show microtubule disruption, p53 stabilization and interference with glucose metabolism as collective underlying mechanisms of Fenbendazole induced preferential elimination of cancer cells both in vitro and in vivo.

My Take…

Ivermectin is FDA approved.

Fenbendazole is NOT approved for human use by Food and Drug Administration (FDA) and European Medicines Agency (EMA). It is available as a veterinary medication.

Fenbendazole is part of a larger group of drugs known as benzimidazoles, which are anthelmintic drugs (i.e., drugs that kill parasitic worms). Another benzimidazole is mebendazole, which can be prescribed to humans with certain parasitic infections.

Mebendazole (Vermox) is FDA approved for human use, but it’s significantly more expensive.

Why is Fenbendazole so popular? The Story of Joe Tippens and his terminal Stage 4 Small Cell Lung Cancer

Joe Tippens Cancer Protocol:

  • Fenbendazole 222mg per day with food (originally 3 days on, 4 days off)
  • Curcumin 600mg per day
  • CBD Oil: 25mg sublingually per day
  • Vitamin E: 800IU per day

Dr. Tom Rogers MD (Performance Medicine – Knoxville, TN) Suggests Several Protocols utilizing Fenbendazole which are interesting:

ACTIVE CANCER TREATMENT – For active cancer, take one capsule of Fenbendazole (444 mg) daily. Some people recommend you take one day off a week. Note: I think I would just take Sundays off. Again, you’re not supposed to develop a tolerance to this, but taking a little break is probably a good idea. To improve the protocol , take CBD oil (25mg) 1-2 drops every night before sleep. To strengthen the protocol take Curcumin (600mg) twice a day with food. To support the liver, take Milk Thistle (250mg) twice a day with food. Note: Fenbendazole should be taken with or after a meal to improve absorption.

COMPLEMENTARY CANCER TREATMENT – Take one capsule of Fenbendazole (222mg) every day, once a day after a fatty meal; Curcumin (600mg) one capsule, two times a day after breakfast and lunch; CBD oil (25mg) 1-2 drops under the tongue every day before sleep.  

CANCER RELAPSE PREVENTION – Taking Fenbendazole for active cancer and cancer relapse prevention, take one capsule (222 mg) three times a week, once a day after a fatty meal.In addition, take Curcumin (600mg) one capsule/two times a day after breakfast and lunch, Milk Thistle, and CBD Oil (25mg) 1-2 drops under the tongue everyday before going to sleep. Note: Have your doctor follow and check liver and kidney function tests. It’s easy, cheap, and you can get this at any doctor’s office.

CANCER PREVENTION (prophylactic) – Those that have had genetic tests and know they’re really prone to getting cancer can take Fenbendazole prophylactically. Take one capsule (222 mg) 3 times a week, once a day after a fatty meal. Then no Fenbendazole for four days. Repeat for 10 weeks and then take 10 weeks off; Curcumin (600 mg) one capsule two times a day after breakfast and lunch; CBD oil (25mg) 1-2 drops under the tongue every day before sleep. Continue that regimen indefinitely.

My Thoughts

Fenbendazole is not that controversial when you consider the scientific evidence objectively.

Fenbendazole has at least 12 proven anti-cancer mechanisms in vitro and in vivo:

  • disrupts microtubule polymerization (major mechanism)
  • induces cell cycle (G2/M) arrest
  • blocks glucose transport and impairs glucose utilization by cancer cells (major)
  • increases p53 tumor suppressor levels (major)
  • inhibits cancer cell viability (mTOR)
  • inhibits cancer cell migration and invasion (EMT pathway)
  • induces apoptosis
  • induces autophagy
  • induces pyroptosis and necrosis
  • induces differentiation and senescence
  • inhibits tumor angiogenesis
  • reduces colony formation and inhibits stem-ness in cancer cells
  • inhibits drug resistance and sensitizes cells to conventional chemo as well as radiation therapy

A very similar drug in the same family as Fenbendazole is FDA approved: Mebendazole, and it is in several Clinical Trials right now for brain cancers and colon cancers.

So why are there no Fenbendazole Clinical Trials for Cancer?

The answer seems rather obvious: it’s very cheap, it’s safe, and it seems to be very effective.

Fenbendazole is not going to make anyone rich, and in cancer treatments, that is a non-starter.

What about COVID-19 mRNA Vaccine Induced Turbo Cancers?

Fenbendazole shows in vitro and/or in vivo activity against these cancers:

  • breast cancer (including triple negative breast cancer – which is seen in COVID-19 mRNA Vaccinated individuals with Turbo Cancer)
  • lymphomas (these are the most common COVID-19 mRNA Vaccine Turbo Cancers and there is more evidence for Fenbendazole with Lymphomas than with Ivermectin)
  • leukemias (most aggressive COVID-19 mRNA Vaccine Turbo Cancers)
  • glioblastomas and gliomas (extremely aggressive COVID-19 mRNA Vaccine Turbo Cancers)
  • lung cancer (NSCLC) (strong signal for COVID-19 mRNA Vaccine Turbo Cancers)
  • hepatocellular carcinoma (signal for COVID-19 mRNA Vaccine Turbo Cancers)
  • rhabdomyosarcomas (possible signal for COVID-19 mRNA Vaccine Turbo Cancers, sarcomas in general are on the rise)
  • ovarian cancers
  • urothelial cancers

CONCLUSION:

Although the anti-parasitic Fenbendazole is not FDA approved for human use, there is extensive evidence of anti-cancer effects in the published literature, both in vitro and in vivo, and this is not a controversial medication, as it has been made out to be.

Fenbendazole has an excellent safety profile and its close relative, Mebendazole is FDA approved, and it’s undergoing several Clinical Trials for Cancer Treatments in the US right now, including colon cancers and brain cancers.

I believe that it is a reasonable hypothesis that COVID-19 mRNA Vaccine Turbo Cancer patients could benefit significantly from either Mebendazole or Fenbendazole and I would love to see urgent clinical trials with both.
