Efficacy and Safety of HA35 Gel for Ultra-Rapid Skin Pruritus Relief (HA35-ITCH)
A Prospective, Single-Arm, Open-Label Pilot Clinical Study to Evaluate Efficacy and Safety of Topical 10% 35 kDa Hyaluronan (HA35) Gel for Ultra-Rapid Relief of Diverse Etiology Skin Pruritus

상세 설명
This prospective, single-center, single-arm, open-label pilot clinical study investigates the ultra-rapid antipruritic efficacy and safety of topical 10% high-concentration 35 kDa hyaluronan (HA35) gel for managing moderate-to-severe skin pruritus caused by various conditions including eczema, neurodermatitis, insect bites, urticaria, and postoperative wound pruritus.
Eligible subjects will receive a single topical application of HA35 gel evenly spread over the pruritic skin area. Pruritus intensity will be assessed using a 0-10 Numeric Rating Scale (NRS) at baseline, 10 seconds, 45 minutes, 8 hours, 12 hours, and 24 hours after application. Changes in associated erythema, swelling, and wheals will also be observed.
Local skin irritation, allergic reactions, and adverse events will be monitored continuously for safety assessment.
This is a non-invasive, non-pharmacological topical intervention with minimal risk to participants. All procedures will be conducted in accordance with the Declaration of Helsinki, and written informed consent will be obtained from all subjects prior to enrollment.
