Keytruda is a medication that has been approved by the US Food and Drug Administration (FDA) to treat various types of cancer. Keytruda's active ingredient is Pembrolizumab, which is a type of immunotherapy drug that works by blocking a protein called PD-1 on the surface of immune cells. By blocking PD-1, Keytruda allows immune cells to recognize and attack cancer cells [1].
According to the information provided by Drug Patent Watch, Keytruda has been granted multiple patents, including one that will expire in 2028 [1]. This suggests that Keytruda has been successful in treating cancer and has been deemed valuable enough to warrant patent protection.
Medical News Today reports that Keytruda has been effective in treating several types of cancer, including melanoma, non-small cell lung cancer, head and neck cancer, and bladder cancer [2]. The article cites several clinical trials that have demonstrated Keytruda's effectiveness in shrinking tumors and improving survival rates in patients with these types of cancer.
In addition to the cancers mentioned above, Keytruda has also been approved to treat certain types of kidney cancer. The official Keytruda website states that Keytruda has been shown to be effective in treating advanced renal cell carcinoma, a type of kidney cancer [3]. The website cites a clinical trial that showed that Keytruda improved overall survival rates in patients with advanced renal cell carcinoma compared to those who received other treatments.
Overall, the sources suggest that Keytruda has been effective in treating several types of cancer, including melanoma, non-small cell lung cancer, head and neck cancer, bladder cancer, and advanced renal cell carcinoma. However, as with any medication, the effectiveness of Keytruda may vary depending on the individual patient and their specific cancer diagnosis. It is important for patients to discuss the potential benefits and risks of Keytruda with their healthcare provider.
