A small Swiss clinical trial suggests that a cardiac drug used for over a century, digoxin (also known as foxglove), may have a surprising new use: inhibiting the spread of cancer.
The Metastatic Threat
Breast cancer metastasis, the spread of cancer from its original site to other organs, is the leading cause of death for women with breast cancer. This makes inhibiting metastasis a crucial area of research.Conventional cancer treatments focus on killing tumor cells, but they have limited effectiveness in preventing metastasis.
one key factor in metastasis is circulating tumor cells (CTCs).These are cancer cells that detach from the primary tumor and enter the bloodstream. When CTCs cluster together, they are more likely to form new tumors in distant organs.
Targeting Cell Clumps
The research team discovered that sodium-potassium ATPase inhibitors, such as foxglove, can disrupt these CTC clumps. Foxglove, first extracted from the Digitalis lanata plant in 1930, has long been used to treat heart failure and atrial fibrillation.
“Foxglove works by blocking sodium-potassium pumps in heart cells, maintaining the balance of sodium and potassium necessary for proper heart function. We believe that this mechanism may also be applicable to cancer treatment,” explains a researcher involved in the study. By inhibiting sodium and potassium pumps in tumor cells, foxglove increases calcium absorption, weakens the connections between cancer cells, and effectively causes them to break apart.
Promising Results, But More Research Needed
To test this hypothesis, researchers conducted a clinical trial involving nine women with metastatic breast cancer.They administered daily doses of foxglove for seven days and monitored circulating tumor cell levels before and after treatment.The results showed a notable reduction in the average size of cancer cell clumps.
“While these findings are promising, it’s crucial to remember that this is a small study and further research is needed to confirm the effectiveness of foxglove in treating cancer,” cautions Dr. Daniel Smit of the University Medical Centre in Hamburg-Ependorf, Germany.
“The overall effect of the drug was relatively small, and foxglove did not prevent CTCs from aggregating with healthy blood cells. moreover, it did not prevent the growth of existing metastatic tumors.
Future Directions
Despite these limitations, the study offers a glimmer of hope for a new approach to cancer treatment. Researchers are exploring the development of new molecules based on foxglove that could be more effective in breaking down CTC clumps and preventing metastasis. These molecules may also be investigated for their potential in treating other types of cancer.
This groundbreaking research was published in the prestigious journal Nature Medicine, highlighting the potential of repurposing existing drugs for new applications in cancer therapy.
While further research is crucial,these findings offer a hopeful new avenue in the fight against cancer.

An Interview with Dr.Lena Petrov, led researcher on the Foxglove Study
A recent clinical trial in switzerland suggests that a cardiac drug used for over a century, digoxin (also known as foxglove), may have a surprising new use: inhibiting the spread of cancer. We spoke to Dr. Lena Petrov, lead researcher on this groundbreaking study, to learn more.
Dr. Petrov, your research suggests that foxglove, a drug primarily used for heart conditions, could have potential in fighting cancer. Can you tell us more about how this discovery came about?
“Our research focused on circulating tumor cells (CTCs), which are cancer cells that break away from the primary tumor and enter the bloodstream. These CTCs can travel to other organs and form new tumors, leading to metastasis, the most deadly aspect of cancer. We knew that breaking up these CTC clusters could significantly reduce the risk of metastasis.
During our exploration of potential inhibitors, we stumbled upon sodium-potassium ATPase inhibitors, a class of drugs that includes foxglove. Foxglove has been used to treat heart failure and atrial fibrillation for decades, primarily by regulating sodium and potassium levels in heart cells. We hypothesized that this same mechanism could disrupt the connections between cancer cells and prevent them from clumping together.”
The trial involved just nine women with metastatic breast cancer. What were the key findings, and how promising are they?
“While this was a small trial, the results were encouraging. We observed a notable reduction in the average size of cancer cell clumps after administering daily doses of foxglove for seven days. this suggests that foxglove can indeed disrupt the formation of these dangerous clusters. However, it’s important to emphasize that this data is preliminary. More extensive research with larger patient populations is crucial to confirm the effectiveness and safety of foxglove in treating cancer.”
What are the next steps in your research, and what challenges do you foresee?
“We’re planning larger-scale clinical trials to further evaluate the efficacy of foxglove in different types of cancer and assess its long-term effects. We’re also investigating the advancement of new molecules based on foxglove’s structure that could perhaps be more potent and specific in targeting ctcs.
One challenge is that foxglove can have side effects, especially at higher doses. We’ll need to carefully monitor patients and determine the optimal dosage for cancer treatment. Another challenge is ensuring that these molecules don’t interfere with healthy cell function. Rigorous testing and safety evaluations are paramount.”
What message would you give to patients hoping for new cancer treatments?
“It’s essential to stay informed about the latest research and discuss treatment options with your doctor. While this study offers a glimmer of hope, it’s still in its early stages. remember,rigorous research and clinical trials are crucial to ensure that any new treatment is safe and effective. But, advancements like this remind us that the search for better cancer treatments is constantly moving forward.”
