Phase I Complete. Phase II Funded. Now, Let’s Advance to Phase III.

Believe Big is honored to be on the front lines of groundbreaking cancer research. In partnership with Johns Hopkins University School of Medicine, we are helping lead the first U.S. clinical trial using intravenous mistletoe, bridging the gap between conventional and complementary medicine in the fight against cancer.

While mistletoe therapy has been widely used in countries like Germany and Switzerland, bringing it into standard oncology care in the United States requires rigorous clinical trials. Each phase builds on the last, answering critical questions about safety, effectiveness, and real-world impact.

We’re thrilled to share that Phase I is complete, demonstrating that mistletoe is safe and showing promising potential to improve patients’ quality of life. Even more exciting, Phase II is now fully funded and about to begin.

But the journey isn’t over.

Phase III is the pivotal step that can open the door to widespread adoption and insurance coverage, making this therapy accessible to patients across the country. And unlike conventional treatments backed by major pharmaceutical funding, this research depends on a community of passionate supporters.

That’s where you come in.

Your support helps move this research forward, bringing hope, expanding treatment options, and changing lives.
