A few days ago, Biogen announced that the non-opioid painkiller vixotrigine failed to achieve the expected goal of reducing the average daily pain of patients during the interim study.
The drug was originally acquired by Bojian's acquisition of Covergence for 675 million in 2015
However, Biogen claimed that vixotrigine achieved a significant improvement in another secondary endpoint (the patient’s self-reported symptom improvement score)
In terms of safety, the two doses of vixotrigine were generally well tolerated by patients, and no potential evidence of opioid abuse was found during the trial
It is worth noting that this is not the first time vixotrigine has faced trial setbacks
