A Randomized Study to Evaluate the Safety and Efficacy of Various Doses of STP705 in Subjects With Hypertrophic Scar


Brief description of study

This is a randomized, double-blind, within-subject placebo controlled study to evaluate the safety and efficacy of various doses of STP705 administered as intradermal Injection in subjects with hypertrophic scar. The goals are to determine the recommended Phase 2 dose, the pharmacokinetics and pharmacidynamics parameters, and conduct analysis of biomarkers common to the scar formation pathway.

Detailed Study Description

This single-center, randomized, double-blind, within-subject placebo controlled study is designed to evaluate the safety and efficacy of various doses of STP705 administered as intradermal injection in subjects with linear hypertrophic scar.

Twenty four subjects will be divided equally among 3 cohorts (20, 30 and 40 g/cm2/day dose level) of 8 subjects each. Each subject will receive both active (STP705) and control (Placebo) treatment twice a week for a total of 4 weeks. The total length of linear hypertrophic scar will be divided equally for treatment with STP705 and placebo. STP705 and Placebo will be injected intradermal every 1 cm length on the hypertrophic scar.

Subjects will be confined to clinic or research unit for 24 hours post-dosing after the first treatment administration for the serial PK assay and the blood sample will be collected at the following post-dosing times: 30 min, 1 hr, 2 hrs, 3 hrs, 4 hrs, 5hrs, 6 hrs, 8 hrs, 12 hrs, 16 hrs, 24 hrs, 32 hrs and 36 hrs. Post-dosing ECG will be performed 6 hours (1 hr) after the first study drug administration and vital signs will be monitored every 2h till 12h post-administration. Adverse events and medications will be monitored throughout the study.

Clinical Study Identifier: NCT02956317
