Efficacy of Oral HA35 for Rapid Relief of Oral Pain and Pungent Sensation

2026년 9월 6일 업데이트: Nakhia Impex LLC

A Prospective, Single-Arm, Open-Label Pilot Clinical Study of Oral 10% 35 kDa Hyaluronan for Rapid Relief of Capsaicin/AITC-Induced Oral Pain and Pungent Sensation

This prospective, open-label, controlled pilot study evaluates oral 10% 35 kDa hyaluronan (HA35) versus four control interventions (C60 grapeseed oil,normal saline) for relief of capsaicin/AITC-induced oral pain and pungent sensation. Healthy participants receive standardized pain induction followed by single oral intervention. Pain/pungency assessed at 30 sec/60 sec/120 sec. Safety monitored throughout. Minimal-risk, non-invasive oral study.

연구 개요

상세 설명

This prospective, single-center, open-label, controlled pilot clinical study evaluates the rapid analgesic and anti-pungent effects of oral 10% 35 kDa hyaluronan (HA35) compared with two control interventions in healthy adults with capsaicin/AITC-induced oral pain and pungent sensation.

Eligible participants undergo standardized pain induction:

Capsaicin (chili) challenge: Oral capsaicin exposure induces oral pain. AITC (wasabi/horseradish) challenge: Oral AITC exposure induces pain and pungency.

After induction, participants are assigned to 6 parallel groups:

HA35:20 mL 10% HA35 oral solution Control 1:20 mL 4 mg/L C60 grapeseed oil Control 2:20 mL normal saline All interventions administered orally, held 3-30 seconds then swallowed.

Outcome assessments:

Oral pain (0-10 NRS) Pungent/irritant sensation (0-10 NRS) Time points: Baseline, 30 sec, 60 sec, 120 sec Safety: Oral adverse events and tolerability monitored throughout. Minimal-risk, non-invasive oral intervention. All procedures follow Declaration of Helsinki; written informed consent obtained.
