FDA Approval of Keytruda: A Game-Changer in Cancer Treatment
The Food and Drug Administration (FDA) has been a driving force behind the development of innovative cancer treatments. One such treatment is Keytruda, a groundbreaking immunotherapy medication that has revolutionized the way we approach cancer care. In this article, we will delve into the history of Keytruda's FDA approval and its impact on the medical community.
What is Keytruda?
Keytruda, also known as pembrolizumab, is a monoclonal antibody that targets the PD-1 protein on T-cells. By blocking this protein, Keytruda enables the immune system to recognize and attack cancer cells more effectively. This innovative approach has made Keytruda a leading treatment option for various types of cancer, including melanoma, lung cancer, and head and neck cancer.
FDA Approval of Keytruda
Keytruda was first approved by the FDA in September 2014 for the treatment of patients with unresectable or metastatic melanoma. This approval marked a significant milestone in the development of immunotherapy treatments for cancer. Since then, Keytruda has received additional approvals for various indications, including:
* October 2015 : Keytruda was approved for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose disease progressed during or after platinum-based chemotherapy.
* December 2015 : Keytruda was approved for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) whose disease progressed on or after platinum-based therapy.
* March 2017 : Keytruda was approved for the treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant chemotherapy.
* October 2019 : Keytruda was approved for the treatment of patients with unresectable or metastatic MSI-H or dMMR colorectal cancer.
Impact of Keytruda's FDA Approval
The FDA approval of Keytruda has had a profound impact on the medical community. According to a study published in the Journal of Clinical Oncology, the approval of Keytruda has led to a significant increase in the use of immunotherapy treatments for cancer. The study found that the use of immunotherapy treatments increased by 25% in the year following Keytruda's approval.
