If a person taking part in a clinical trial on medicinal products is not able to give consent on taking part in the trial, the person may not, deviating from the provision in paragraph 1, be research subject unless the person’s close relative or other person closely connected with the person or his/her legal representative, after having been informed about the nature, meaning, effects and risks of the clinical trial, gives consent to taking part in the trial. The consent must be in accordance with the research subject’s supposed will.
