Only requests received from the licensed physician on behalf of the patient will be considered. CSL Behring will assess the request against the above criteria. If these criteria are met and the IRB/Ethics Committee and FDA approve access to the experimental therapy, early access may be granted. US medicine importation requirements must also be met. The patient's physician is responsible for the patient's ongoing care as well as all relevant US federal and state legislations while the patient is receiving the experimental medicine through early access. If approved the patient/caregiver must provide informed consent and the treating physician must follow safety and monitoring requirements as defined by CSL Behring.
