HB 3455 establishes new disclosure requirements and liability provisions for manufacturers of experimental drugs and devices. It defines "experimental drugs or devices" as those that are investigational, experimental, or approved by the U.S. Food and Drug Administration for emergency use. The bill mandates that manufacturers provide purchasers with a disclosure form detailing potential adverse health effects, which must then be shared with consumers before the product is sold or administered. Consumers must sign the disclosure form to acknowledge informed consent. If a consumer experiences harm due to a violation of these disclosure requirements, they may sue the manufacturer for damages, including compensatory and exemplary damages, as well as attorney's fees. This law applies only to causes of action arising after its effective date.
