Clinical Trial Summary

This is a multicenter, dose-ranging study including adult male and female subjects (>= 18 years old) with symptomatic Oral Lichen Planus (OLP). A total of approximately 24 subjects will be enrolled at approximately five (5) study sites in the United States. This study will evaluate the safety, tolerability and efficacy of LP-10 at 0.25 mg, 0.5 mg and 1.0 mg of tacrolimus.The study consists of screening, treatment and follow-up phases. The treatment phase includes 10 mL LP-10 oral rinse for 3 minutes twice a day for 4 weeks. The follow-up phase includes one post-treatment visit 2 weeks after the last oral LP-10 dose.

• Active cancer

• Uncontrolled hypertension (i.e., > 145 mm/Hg systolic or > 95 mmHg diastolic)

• Patients who failed tacrolimus treatment for OLP in the past

• Patient who is currently or has previously participated in another oral cavity therapeutic or device study within 3 months of screening and has not returned to baseline

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The primary endpoint of this study is safety assessed by incidence of Treatment-Emergent Adverse Events	Safety data will be collected by ongoing monitoring of adverse events	through study completion, an average of 10 weeks
Secondary	Measure the objective effect of LP-10 on OLP by Focused Oral Examination including Intraoral Images	Investigator will conduct the oral exam with intraoral images	an average of 10 weeks
Secondary	Measure the objective effect of LP-10 on OLP by OLP Investigator Global Assessment (IGA)	Investigator will complete the OLP IGA score	An average of 10 weeks
Secondary	Measure the objective effect of LP-10 on OLP by Reticulation, erythema, and ulceration (REU) score	Investigator will complete the OLP REU score	an average of 10 weeks
Secondary	Measure the objective effect of LP-10 on OLP by Oral Lichen Planus Symptom Severity Measure (OLPSSM)	Patient will complete the OLPSSM	an average of 10 weeks
Secondary	Measure the objective effect of LP-10 on OLP by Patient Global Response assessment (GRA)	Patient will complete the GRA	At week 4 visit
Secondary	Measure the objective effect of LP-10 on OLP by Pain and sensitivity numerical rating scale (NRS)	Patient will complete the Numerical Rating Scale (NRS) a scale from 0 - 10, higher score is a worse outcome	an average of 10 weeks
