CHMP Renders Positive Opinion on Thelin This morning the EMEA > announced that the Committee for Medicinal Products for Human Use > (CHMP) adopted positive opinions on initial marketing authorization > applications for Thelin. Based on this opinion we expect the EMEA to > approve Thelin for marketing in the European Union within the next 90 > days. > Positive Repercussions for Thelin Approval by the US FDA in Our > Opinion A positive CHMP opinion indicates to us that the safety issues > with Thelin noted by the FDA may not be that serious. We are more > inclined to think now that the management's recent response to the > approvable letter from the FDA may be sufficient and that they may not > need to conduct another clinical study. > ENHANCED THELIN MARKETING POSITION Given that an additional clinical > trial may not be needed to address the observations and concerns cited > by the FDA in the approvable letter issued on Thelin NDA earlier this > year, we now believe Thelin is more likely to be approved ahead of > ambrisentan (1H07 vs. 2H07). As a reminder, Myogen (MYOG, Not Rated) > previously disclosed it will not file for approval until 4Q06. > THELIN PRESENTS a $200 MM OPPORTUNITY With the reduced regulatory > hurdle, we now expect Thelin to enter U.S. market in 1H07, ahead of > ambrisentan. We expect Thelin to achieve peak sales of $200 MM in > 2012. We believe that while Ambrisentan will be the best-in-class ERA > for the treatment of PAH, recent data at ATS and convenience of dosing > suggest to us that Thelin should be able to garner a significant > market share in the PAH market. It is noteworthy that Thelin has been > shown to be effective in treating Tracleer failing patients. > Upgrade to Market Outperform ENCY shares have traded down > significantly since receiving the FDA approvable letter earlier this > year. Despite the pre-market run-up we would be buyers of the stock at > the open. The CHMP opinion signals to us that safety concerns > associated with Thelin may not be as difficult to address as we > originally thought of. We therefore upgrade ENCY shares to Market > Outperform with a 12-month price target of 10 is based on applying a > 35x to our 2010 EPS estimate of $0.61 discounted annually by 25% for > 3.5 years. > KEY RISK FDA request for an additional trial for Thelin approval > > > <<ENCY Note CHMP positive opinion Final.pdf>> > > > Navdeep S.
