“The most promising advances in oncology rarely come from a single “magic bullet.” Instead, they emerge from intelligent combinations—using different drugs together to attack cancer from multiple angles.”

“At Courage Against Cancer, we believe the greatest potential for repurposed drugs like ivermectin and mebendazole may not be as standalone cures, but as powerful allies to the standard treatments you already know.”

Beyond the “Instead Of”: A New Paradigm

For too long, the conversation around repurposed drugs has been framed as “instead of” chemotherapy or radiation. This creates a false and dangerous dichotomy. Our research focuses on a more sophisticated and promising question: Can these drugs work with standard care to make it more effective? This approach, known as combination therapy, is the cornerstone of modern oncology, and it’s time we applied rigorous science to see if these affordable, accessible drugs can play a vital role.

Mebendazole: Disrupting the Cancer Cell’s Scaffolding

Mebendazole belongs to a class of drugs called anthelmintics, designed to paralyze and kill parasites. Its anti-cancer potential, observed in numerous lab studies, operates on a similar principle. Many aggressive cancers are driven by rapid cell division, a process that relies on tiny internal structures called microtubules—essentially, the cell’s scaffolding and transportation system.

• The Mechanism: Research, including seminal work on glioblastoma at Johns Hopkins, shows that mebendazole disrupts these microtubules. This prevents cancer cells from properly dividing, effectively stopping tumor growth and triggering cell death.
• The Synergy: This mechanism is strikingly similar to a class of expensive IV chemotherapy drugs called vinca alkaloids. The compelling hypothesis is that adding mebendazole could enhance this microtubule-disrupting effect, potentially allowing for lower doses of toxic chemo or overcoming resistance.

Ivermectin: A Multi-Pronged Attack on Cancer Pathways

Ivermectin’s potential is even more complex and multifaceted. While also an anti-parasitic, it appears to interfere with cancer through several distinct pathways simultaneously, making it an intriguing partner for combination therapy.

• Targeting the Powerhouse: It can disrupt the function of mitochondria—the energy powerhouses of cells—in cancer cells, effectively starving them of the power they need to survive and proliferate.
• Inhibiting Resistance: Some studies suggest it can inhibit key pathways (like Wnt/β-catenin and AKT/mTOR) that cancers use to grow, spread, and, crucially, develop resistance to conventional therapies.
• The Synergy: By targeting these “survival” pathways, ivermectin could potentially sensitize a tumor to the effects of radiation or chemotherapy, making the standard treatment more effective than it would be alone.

The Powerful Concept of Synergy

Synergy is not just 1 + 1 = 2. In the best cases, it’s 1 + 1 = 3. It means the combined effect of two treatments is greater than the sum of their individual effects. Using a repurposed drug to weaken cancer cells and make them more vulnerable to a standard therapy is a powerful strategy to improve progression-free survival and overall outcomes.

Our Flagship Trial: A Vision for Answers

Talk is cheap without data. That’s why Courage Against Cancer is dedicated to moving from hypothesis to proof. We are in the advanced planning stages of our first flagship preclinical trial, designed to answer this critical synergy question.

Our Research Pathway: From the Lab to the Clinic

At Courage Against Cancer, we believe in a disciplined, step-wise research approach to ensure our resources are focused on the most promising leads. While our ultimate goal is to launch definitive human clinical trials, we are currently investing in critical preclinical research to build the strongest possible foundation.

Our Current Focus: A Preclinical Proposal for Ovarian Cancer

We have an active, fully-designed research proposal to investigate the synergistic effects of ivermectin and mebendazole against ovarian cancer in a controlled laboratory setting. This vital preclinical study will use validated animal models to:

• Confirm Efficacy: Rigorously test whether the combination of these repurposed drugs with standard chemotherapy (like carboplatin and paclitaxel) is more effective at shrinking tumors and preventing recurrence than chemotherapy alone.
• Establish Dosing: Identify the most effective and tolerable dosing schedules for these combinations, creating a blueprint for future human trials.
• Understand Mechanisms: Analyze tumor tissue to better understand how these drugs work together at a molecular level to enhance the effect of standard care.

This targeted research in ovarian cancer—a area with high unmet need and a strong scientific rationale for this approach—is the essential next step. The data generated will be the critical evidence required to design and fund the large-scale human trials we all want to see.

The Future Vision: A Human Clinical Trial

The success of this preclinical work will pave the way for our ultimate goal: a randomized, controlled human trial. In this future trial, patients with advanced ovarian cancer receiving standard chemotherapy would be randomized to also receive mebendazole, ivermectin, or a placebo. The primary goal would be clear and measurable: to see if the repurposed drug groups experience a statistically significant improvement in progression-free survival.

This is the kind of trial that can change medical practice, but it will not happen without the solid evidence we are working to produce right now.
