What Was Keytruda's First FDA-Approved Cancer Type?

Unlocking the Power of Immunotherapy

Immunotherapy has revolutionized the way we treat cancer, and Keytruda (pembrolizumab) has been at the forefront of this revolution. Developed by Merck & Co., Keytruda is a programmed death receptor-1 (PD-1) inhibitor that has shown remarkable efficacy in treating various types of cancer. But what was Keytruda's first FDA-approved cancer type? Let's dive into the history of this groundbreaking drug.

The Early Days of Immunotherapy

Immunotherapy has been around for decades, but it wasn't until the 1990s that researchers began to understand the role of the immune system in fighting cancer. The discovery of checkpoint inhibitors, such as PD-1, marked a significant turning point in the development of immunotherapy.

Keytruda's Early Trials

Keytruda was first approved by the FDA in 2014 for the treatment of advanced melanoma, a type of skin cancer. But before that, the drug underwent extensive clinical trials to test its safety and efficacy.

The First FDA Approval: Advanced Melanoma

On September 4, 2014, the FDA approved Keytruda for the treatment of advanced melanoma, specifically for patients with unresectable or metastatic melanoma who had progressed after prior treatment with ipilimumab (Yervoy) and, if BRAF V600 mutation-positive, a BRAF inhibitor.

The Science Behind Keytruda's Success

Keytruda works by blocking the PD-1 receptor on T-cells, allowing them to recognize and attack cancer cells. This is particularly effective in treating melanoma, as the cancer cells often express high levels of PD-L1, a protein that binds to PD-1 and inhibits the immune response.

The Impact of Keytruda's First FDA Approval

Keytruda's first FDA approval marked a significant milestone in the development of immunotherapy. It showed that a PD-1 inhibitor could be effective in treating a range of cancer types, including melanoma.

The Future of Immunotherapy

Since its first FDA approval, Keytruda has been approved for the treatment of several other cancer types, including non-small cell lung cancer, head and neck squamous cell carcinoma, and classical Hodgkin lymphoma. The drug has also been studied in combination with other immunotherapies and chemotherapy, showing promising results.

Expert Insights

"We're seeing a shift in the way we treat cancer, from traditional chemotherapy to immunotherapy," says Dr. David F. McDermott, a medical oncologist at Massachusetts General Hospital. "Keytruda has been a game-changer in this regard, and its approval for advanced melanoma marked a significant turning point in the development of immunotherapy."
