A Phase 2, Open-label and Single-Blind Study to Evaluate the Microbiology, Safety and Tolerability of C16G2 Varnish and Strip Administered in Multiple Doses to Adolescent and Adult Dental Subjects

Detailed Summary

An open-label and single-blind phase 2 study to evaluate the oral microbiology, safety and tolerability of multiple C16G2 Varnish and Strip applications in male and female dental subjects 12-75 years of age. The study will compare multiple study drug administrations of C16G2 Varnish and/or C16G2 Strip in three study arms. In Study Arm 1 eight subjects will be enrolled in an open-label manner and will receive a daily dose of C16G2 Varnish application over 3 days followed by 14 doses of C16G2 Strip administered over 7 days. Following the three C16G2 Varnish applications, each subject will receive 7 days of AM and PM dosing with C16G2 Strip and will be followed for microbiology for up to 2 months after the last study drug administration. Study Arm 2 will enroll 12 subjects in a single-blind manner. Subjects will receive four C16G2 Varnish or Placebo applications over 7 days, followed by 3 additional weekly varnish administrations. Subjects will be followed for microbiology for up to 2 months after the last study drug administration.The treatment allocation will be 1:1 (6 subjects receiving C16G2 Varnish, 6 subjects receiving Placebo). Study Arm 3 will be initiated based on the Sponsor's review of all microbiology data up to two week post last study drug administration from Study Arm 2. If initiated, Study Arm 3 will enroll 6 subjects in an open-label manner. Subjects will receive daily single doses of C16G2 Varnish over 10 days, for a total of 10 doses and will be followed for microbiology for up to 2 months after the last study drug administration.
