In this regard the noninferiority of NeuroBloc compared to Botulinum Toxin Type A is also supported by a responder analysis using the ITT population, which showed that a similar percentages of subjects showed any improvement in the TWSTRS score at Week 4 of Session 1 (86% NeuroBloc and 85% Botox), as did subjects who experienced at least a 20% decrease from baseline in the TWSTRS score at Week 4 of Session 1 (51% NeuroBloc, 47% Botox).
