The second quarter was a landmark in our history, as we transformed Insmed into a Phase 3 development stage company, and achieved several significant milestones. First, we made substantial progress in advancing ARIKACE in the clinic in our two priority orphan diseases, and we remain on track for achieving top-line results for CLEAR-108 and TARGET-NTM in mid-2013 and the fourth quarter of 2013 respectively.
Second, we substantially strengthened our financial position through the $20 million loan agreement with Hercules Technology Growth Capital. And finally, we reinforced our already strong intellectual property position as a second composition of matter patent was issued in the U.S. for ARIKACE and liposomal aminoglycosides in general.
Following a careful and thoughtful evaluation of the ARIKACE clinical development options, we announced in May that the company’s resources would be applied towards the CLEAR-108 Phase 3 European and Canadian registration study in Cystic Fibrosis patients who had Pseudomonas Lung Infections and the TARGET-NTM Phase 2 trial of ARIKACE in patients with recalcitrant or resistant non-tuberculous mycobacteria lung disease.
CLEAR-108 compares ARIKACE to TOBI, the market-leading inhaled antibiotic from Novartis for three complete 28-day on-treatment and 28-day off-treatment cycles in about 300 patients. We dosed the first patient in April and remain on target to have top-line data in mid 2013. We are rapidly bringing sites online, in fact about 65 of the 80 planned sites have been activated and are recruiting patients.As a reminder, patients who complete CLEAR-108 are eligible to enroll in CLEAR-110, which is an open-label study in which patients receive ARIKACE every other month for up to two years to assess primarily safety and tolerability. Open-label simply means physicians and patients will know that the patients are receiving ARIKACE. As previously reported, we are deferring plans to initiate CLEAR-109, a Phase 3 study of ARIKACE in the U.S. for CF patients who have Pseudomonas Lung Infections until the company reviews top-line results from CLEAR-108. These results could provide additional clarity on the scope, design and conduct of the U.S. study. In addition, the deferral of CLEAR-109 allows us to allocate capital resources to our prioritized ARIKACE studies.
