2. For the positive P2 data released on 9/12/12 for eravacycline against complicated intra-abdominal infections (http://ir.tphase.com/releasedetail.cfm?ReleaseID=747618 ), there seems to be comparable cure rate with ertapenem. So, similar questions as in 1. What separates TTPH's eravacyline from ertapenem and will the drug be able to capture a meaningful portion of ertapenem's market? How close is ertapenem to going generic? Are there other competitive threats in this specific space to worry about beyond ertapenem?
