Clinical and microbial evaluation of a histatin-containing mouthrinse in humans with experimental gingivitis: a phase-2 multi-center study.

AbstractOBJECTIVE:
P-113, a 12 amino acid histatin-based peptide, was evaluated in a mouthrinse formulation for safety and efficacy in a phase 2 multi-center clinical study.
METHOD:
294 healthy subjects abstained from oral hygiene procedures and self-administered either 0.01% P-113, 0.03% P-113 or placebo mouthrinse formulations twice daily over a 4-week treatment period. During this time, the safety, anti-gingivitis, and anti-plaque effects of P-113 were evaluated.
RESULTS:
There was a significant reduction in the change from baseline to Day 22 in bleeding on probing in the 0.01% P-113 treatment group of the intent to treat population (p=0.049). Non-significant trends in the reduction of the other parameters were observed in this population (p> or =0.159). A sub-group of subjects which developed significant levels of disease within the four-week timeframe of the study was identified based on baseline gingival index scores > or =0.75. Significant findings were observed for bleeding on probing, gingival index and plaque index within this population (p<0.05). There were no treatment-related adverse events, and there were no adverse shifts in supragingival microflora during the study. Significant amounts of the peptide were retained in the oral cavity following rinsing.
CONCLUSION:
These data suggest that P-113 mouthrinse is safe and reduces the development of gingival bleeding, gingivitis and plaque in the human experimental gingivitis model.
