Further reference is made to Avanthi’s January 3, 2018, February 9, 2018, and May 22, 2018 correspondences to OPDP in response to the Warning Letter and to OPDP’s January 26, 2018, and May 30, 2018

OPDP’s Warning Letter requested that Avanthi immediately cease misbranding Lomaira and/or cease introducing the misbranded drug into interstate commerce as discussed in the Warning Letter, submit a written response on or before January 4, 2018, stating whether you intended to comply with this request, list all promotional materials (with the 2253 submission date) for Lomaira that contain statements such as those described in the Warning Letter, and explain Avanthi’s plan for discontinuing use of such materials, or, in the alternative, for ceasing distribution of Lomaira.
