Mo. Rev. Stat. § 630.192
No biomedical or pharmacological research shall be conducted in any mental health facility or mental health program in which people may be civilly detained pursuant to chapter 632 or in any public or private residential facilities or day programs operated, funded or licensed by the department for persons affected by intellectual disabilities, developmental disabilities, mental illness, mental disorders or alcohol or drug abuse unless such research is intended to alleviate or prevent the disabling conditions or is reasonably expected to be of direct therapeutic benefit to the participants. Without a specific court order, no involuntary patient shall consent to participate in any biomedical or pharmacological research. The application for the order shall be filed in the court having probate jurisdiction in the county in which the mental health facility is located, provided, however, that if the patient requests that the hearing be held by the court which has committed the patient, or if the court having probate jurisdiction deems it appropriate, the hearing on the application shall be transferred to the committing court.
