Nabriva's Antibiotic Aces a Late-stage Trial In China.

Nabriva Therapeutics NBRV and partner Sinovant Sciences announced positive topline results from Sinovant's Phase 3 bridging study of lefamulin in Chinese adults with community-acquired bacterial pneumonia.

Consistent with previously reported clinical trial results, lefamulin was observed to be generally safe and well-tolerated, with an overall rate of treatment-emergent adverse events comparable to that of moxifloxacin.

Sinovant also announced an agreement with Sumitomo Pharmaceuticals to acquire development and commercialization rights for lefamulin in Greater China.

Nabriva's Lefamulin was approved to treat CABP in the U.S. in August 2019 and is marketed under the trade name Xenleta.
