*Federal Register* notice: FDA has reopened the comment period for a 9/26/2017 notice announcing a public hearing on a potential approach for device sponsors who seek to obtain marketing authorization for their products that are intended for a new use with an approved, marketed drug when the drug sponsor does not wish to pursue or collaborate on the new use. In the document, in addition to seeking comments on the potential approach, FDA also welcomed comments on public health, scientific, regulatory, or legal considerations relating to other medical products intended for new uses with approved, marketed medical products of a different type where the sponsor for the approved product does not want to pursue or collaborate on the new use.
