Comment :
The life- threatening situation requires a timely decision so that the test article can be ethically used. It would be unethical to withhold emergency treatment until a research protocol is submitted and approved by the IRB. Not using the test article in a situation where it might save a life is also unethical. The Federal regulations (21 CFR 50.24) provide the option of using the test article in a life-threatening condition involving an individual subject where the following requirements for an exception from informed consent are met. 1. The investigator, with the concurrence of another physician, believes the situation necessitates the use of a test article (i.e., an investigational drug, device, or biologic). 2. The subject and/or legally authorized representative is unable to communicate consent. 3. There is insufficient time to obtain consent. And 4. No alternative exists that will provide an equal or better chance of saving the subject's life.
