How many people have died taking ACTEMRA?

Can you please provide me with some context on ACTEMRA and why it's important to know how many people have died while taking it? Is ACTEMRA a widely prescribed medication, and if so, what is it used to treat? Are there any known risks or side effects associated with its use? Furthermore, how does the number of deaths compare to other similar medications or treatments for the same condition? Lastly, have there been any recent studies or investigations into the safety of ACTEMRA, and what do they suggest in terms of its potential risks?
