In a May 2014 letter to Acura, FDA questioned the relevance of abuse of hydrocodone with acetaminophen products by nasal snorting after reviewing clinical and epidemiology data submitted by Acura.
The FDA continues to question the relevance of abuse of hydrocodone with acetaminophen products by the intranasal route of administration and suggested additional information may help better inform their decision.
The FDA indicated in the discussions that Acura may conduct an additional nasal abuse liability study for its AVERSION hydrocodone with acetaminophen product candidate, the outcomes of which may help inform the relevance decision as well as establish a reduction in drug liking, which was not statistically significant in an earlier Acura study (Study AP-ADF-301).
The FDA requested further time to deliberate on the issues discussed during the meeting before issuing final meeting minutes.
Acura intends to review its clinical data from Study AP-ADF-301 to determine whether to proceed with an additional clinical study for its AVERSION hydrocodone with acetaminophen product candidate and to further evaluate options to address the issues of intranasal abuse and drug liking raised by the FDA.
