Forest Laboratories, Inc. (NYSE: FRX) and Almirall, S.A. (ALM:MC) today announced that they will delay the planned Q4 2013 submission of a New Drug Application (NDA) for the combination of aclidinium bromide, a long acting muscarinic antagonist and formoterol fumarate, a long acting beta agonist, for the indication of Chronic Obstructive Pulmonary Disease (COPD). This decision was based on comments provided by the FDA at a recent pre-NDA meeting.
The delay is related to resolving chemistry, manufacturing and control (CMC) specifications associated with the combination formulation. Forest and Almirall are working with the FDA regarding the CMC related comments provided at the pre-NDA meeting to determine the appropriate next steps, and expects to provide an update when more information becomes available. The decision to delay the NDA filing for the combination does not affect the Tudorza ® (alcidinium bromide) monotheraphy product.
Forest and Almirall recently announced positive phase III results from two pivotal clinical trials for aclidinium/formoterol. The combination was administered twice a day and primary end points were met which demonstrated statically significant improvements versus placebo. In addition, aclidinium/formoterol was well tolerated in both studies.Aclidinium bromide /formoterol fumarate is an investigational fixed dose combination of two approved long-acting bronchodilators with different mechanisms of action and similar pharmocodynamic profiles. Aclidinium bromide is an anticholinergic or long-acting muscarinic antagonist (LAMA) that produces bronchodilation by inhibiting the muscarinic M3 receptor in the airway smooth muscle. Formoterol fumarate is a long-acting beta-agonist (LABA) that stimulates the B2-receptors in the bronchial smooth muscle resulting in bronchodilation. Both aclidinium bromide (Tudorza ®/ Eklira ®) and formoterol fumarate are approved for the maintenance treatment of COPD in the United States and Europe.
