BI Wants COPD Triple-Combination Restrictions
Boehringer Ingelheim says FDA should ensure that any NDA for a fixed-dose, triple-combination, inhaled drug product intended to treat patients with chronic obstructive pulmonary disease is not approved as safe and effective unless it meets Combination Rule requirements. In a petition, the company asks that FDA not approve any such NDA unless:
- it is supported by pivotal Phase 3 clinical trials that use active comparators containing the same active ingredients as those contained in the proposed triple-combination therapy and not simply active ingredients in the same therapeutic categories; and
- it is supported by pivotal Phase 3 clinical trials that use a factorial design adequate to demonstrate that each active ingredient in the proposed triple-combination makes a contribution to the claimed effects.
The petition also asks that a meeting of the Pulmonary-Allergy Drugs Advisory Committee be convened before the agency approves any NDA for a fixed-dose, triple-combination product for treating patients with COPD that does not meet the Combination Rule requirements described in the petition.
According to Boehringer Ingelheim, GlaxoSmithKline announced 11/21/16 that it had submitted an NDA for a once-daily, closed triple-combination therapy containing fluticasone furoate, umeclidinium, and vilanterol for treating patients with COPD. It says that if approved, it would be the first such inhaled combination available in the U.S. The petition says that the primary support for the application appears to be the FULFIL study that does not allow a comparison of the triple-combination to any of the active ingredients in the combination or any combinations of those active ingredients. The petition says that Glaxo reportedly is conducting a second Phase 3 trial, IMPACT, that will compare the triple-combination ingredients against two approved once-daily products containing combinations of the active ingredients in the triple-combination.
