In the third quarter of 2011, the FDA placed a clinical hold on our phase 3 U.S. clinical trials for ARIKACE in CF patients with Pseudomonas lung infections and for patients with NTM lung infections.

In January 2012, the FDA lifted the clinical hold on ARIKACE in patients with NTM lung infections. In February 2012, we announced that we would be initiating the ARIKACE NTM trial as a phase 2 trial, as well as the previously planned phase 3 trial for ARIKACE in the CF indication in Europe.
