Breaking Down the Barriers: The FDA Approval of Keytruda for Cancer Treatment
The journey of cancer treatment has been a long and arduous one, with numerous breakthroughs and setbacks along the way. One of the most significant developments in recent years has been the approval of Keytruda, a revolutionary immunotherapy drug that has shown remarkable promise in the fight against cancer. But when was Keytruda first approved by the FDA for any cancer treatment?
The Early Days of Immunotherapy
Immunotherapy, a type of cancer treatment that harnesses the power of the immune system to fight cancer, has been around for decades. However, it wasn't until the early 2000s that researchers began to make significant breakthroughs in the field. One of the pioneers in this area was Dr. James Allison, who discovered the CD28 receptor and its role in T-cell activation. This discovery laid the foundation for the development of checkpoint inhibitors, a type of immunotherapy that has since become a cornerstone of cancer treatment.
The FDA Approval of Keytruda
Fast forward to 2014, when the FDA approved Keytruda (pembrolizumab) for the treatment of patients with unresectable or metastatic melanoma who had progressed after prior treatment. This was a major milestone in the history of cancer treatment, marking the first time that an immunotherapy drug had been approved for the treatment of melanoma.
The Expansion of Keytruda's Indications
Since its initial approval, Keytruda has been approved for the treatment of several other types of cancer, including:
* Head and Neck Squamous Cell Carcinoma (HNSCC): In 2016, the FDA approved Keytruda for the treatment of patients with recurrent or metastatic HNSCC who had progressed after prior treatment.
* Classical Hodgkin Lymphoma (cHL): In 2017, the FDA approved Keytruda for the treatment of patients with cHL who had relapsed or progressed after autologous stem cell transplantation or three or more prior lines of therapy.
* Non-Small Cell Lung Cancer (NSCLC): In 2017, the FDA approved Keytruda for the treatment of patients with NSCLC who had progressed after prior treatment with chemotherapy.
The Future of Cancer Treatment
The approval of Keytruda has opened up new avenues for cancer treatment, offering patients a range of options that were previously unavailable. As researchers continue to explore the potential of immunotherapy, we can expect to see even more breakthroughs in the years to come.

Frequently Asked Questions
1. What is Keytruda?
Keytruda is a type of immunotherapy drug that works by harnessing the power of the immune system to fight cancer.
2. What is the mechanism of action of Keytruda?
Keytruda works by blocking the PD-1 receptor, which is a protein on the surface of T-cells that helps to regulate their activity. By blocking this receptor, Keytruda allows T-cells to recognize and attack cancer cells more effectively.
3. What are the approved indications for Keytruda?
Keytruda is approved for the treatment of patients with unresectable or metastatic melanoma, head and neck squamous cell carcinoma, classical Hodgkin lymphoma, and non-small cell lung cancer.
4. How does Keytruda compare to other cancer treatments?
Keytruda has shown remarkable promise in the fight against cancer, offering patients a range of options that were previously unavailable. It has been shown to be effective in treating a range of cancer types, and has a relatively mild side effect profile compared to other cancer treatments.
5. What is the future of cancer treatment with Keytruda?
The approval of Keytruda has opened up new avenues for cancer treatment, and researchers continue to explore the potential of immunotherapy. We can expect to see even more breakthroughs in the years to come.
