When Did Keytruda Gain FDA Approval for Use in Cancer Therapy?
Introduction
Cancer is a devastating disease that affects millions of people worldwide. The treatment options for cancer have evolved significantly over the years, and immunotherapy has emerged as a promising approach. One of the most widely used immunotherapies is Keytruda, a medication developed by Merck & Co. In this article, we will explore the journey of Keytruda's approval by the US Food and Drug Administration (FDA) for use in cancer therapy.
Early Development and Clinical Trials
Keytruda, also known as pembrolizumab, is a humanized monoclonal antibody that targets the PD-1 receptor. The development of Keytruda began in the early 2000s, with the first clinical trials commencing in 2008. The initial studies focused on the treatment of advanced melanoma, a type of skin cancer.
FDA Approval for Melanoma
On September 4, 2014, the FDA granted accelerated approval to Keytruda for the treatment of patients with unresectable or metastatic melanoma who had progressed after prior therapy. This marked a significant milestone in the development of immunotherapy for cancer treatment.
Expansion of Indications
Building on the success of Keytruda in melanoma, Merck & Co. conducted clinical trials to evaluate its efficacy in other types of cancer. In 2015, the FDA approved Keytruda for the treatment of patients with classical Hodgkin lymphoma who had progressed after autologous stem cell transplant and brentuximab vedotin.
Breakthrough Therapy Designation
In 2015, the FDA granted Breakthrough Therapy Designation to Keytruda for the treatment of patients with advanced non-small cell lung cancer (NSCLC) whose tumors express PD-L1. This designation expedited the development and review process for Keytruda, allowing it to reach patients more quickly.
FDA Approval for NSCLC
On October 2, 2015, the FDA approved Keytruda for the treatment of patients with advanced NSCLC whose tumors express PD-L1 with a combined positive score (CPS) of 1 or higher. This marked the first FDA approval of an immunotherapy for NSCLC.
Widespread Adoption
Since its initial approval, Keytruda has been approved for use in multiple cancer types, including head and neck squamous cell carcinoma, small cell lung cancer, and cervical cancer. Its widespread adoption has led to significant improvements in patient outcomes, including increased overall survival rates and reduced toxicity.
Cost and Access
Despite its life-changing benefits, Keytruda is a costly medication, with a list price of over $12,000 per month. This has raised concerns about access and affordability, particularly for patients with limited financial resources. As a result, Merck & Co. has implemented various programs to reduce the cost of Keytruda, including patient assistance programs and copay assistance programs.
Conclusion
Keytruda's journey to FDA approval has been marked by significant milestones and breakthroughs. From its initial approval for melanoma to its widespread adoption across multiple cancer types, Keytruda has revolutionized the treatment of cancer. As the landscape of cancer therapy continues to evolve, Keytruda remains a vital component of the fight against this devastating disease.
