You dying to a disease is nobody's fault (usually). You dying to a bad drug is arguably someone's fault, and I suppose there are probably not any number of documents you can sign that will completely abdicate the responsibility for your death from the corporation that created the chemical compound that resulted in your demise.
And probably for good reason? I really don't want to live in a society that gives people the ability to sign their life away so corporations can run scientific experiments on them that have a real chance of death.
I think there are some exceptions to this, but generally it makes sense to not let people go from "dying of a disease" to, "dying of a drug".
The proper, moral, and correct thing to do is to allow each individual to decide for themselves after being presented with the facts on the risks, probabilities, and benefits.

In a free country, you don't really have the moral authority to make such decisions for other people. After all, you aren't wearing their shoes.
There is no moral way to let people decide for themselves if they want to be experimented on by pharmaceutical corporations.
In a free country, you absolutely have the moral authority (and imperative) to protect those who cannot protect themselves from being taken advantage of.
