Clinical Trial Summary

The purpose of this study is to determine the effect of the placement of a PerioChip Plus (flurbiprofen/chlorhexidine - FBP/CHX) formulation versus PerioChip (chlorhexidine) formulation versus Flurbiprofen Chip formulation versus Placebo Chip formulation on probing pocket depth (PPD)

Description:

This is an 80 subjects, single-center, randomized, double-blinded, parallel, 4-arm clinical study (25 subjects in the PerioChip Plus and PerioChip arms and 15 subjects in the Flurbiprofen Chip and Placebo Chip arms).

At 24 weeks, relative to baseline, the mean reductions in probing pocket depth (PPD) will be used as primary efficacy endpoint. Additional primary endpoints are clinical attachment levels (CAL) and bleeding on probing (BOP) in the target pockets selected at screening, measured at weeks 24.

PPD measurements at 6, 12 and 18 weeks will be used as secondary endpoints. Additional secondary endpoints are clinical attachment levels (CAL) and bleeding on probing (BOP) in the target pockets selected at screening, measured at weeks 6, 12 and 18.
