Clinical Trial Summary

This first-in-man (FIM) phase I study will evaluate the acute safety, tolerability, and acceptability of the investigational RD19 device among 25 healthy volunteers between the age of 18 and 45.

Description:

This first-in-man (FIM) phase I study will evaluate the acute safety, tolerability,and acceptability of the investigational RD19 device among 25 healthy volunteers between the age of 18 and 45. Based on the results of numerous preclinical studies, a short 3 minute use twice a day, separated by at least 4 hours, preferably 8 to 12 hours apart) will be evaluated.

Safety and tolerability (local reactogenicity) will be assessed actively at the following study days: screening (baseline set), 1, 7 and 14, and on non-clinic visit days by collection of these data by history during clinic visits via a memory aid (diary cards). Volunteers will be encouraged to promptly contact designated clinical trial staff or the one of the Sponsor's Emergency Response Team for AEs of a medically urgent nature.

A Comprehensive Metabolic Panel, as well as CBC with differential, urinalysis, and pregnancy testing will be performed at screening and at Day 14 or early termination (and potentially during unscheduled) clinic visits. Hematological safety assessments (evaluation of methemoglobinemia) will be performed at all visits.

Study volunteers will be asked to immediately contact the clinical coordinator and/or the PI in all instances where they experience an AE of greater than moderate intensity. Volunteers will be instructed to report to the clinical trial unit for an unscheduled visit or to seek the appropriate level of medical care based on the nature of their AE/SAE. In all such instances, all relevant information pertaining to these significant medical events will be captured on the appropriate e-CRFs.

Hematology safety laboratory evaluations will be performed at screening, as well during all scheduled clinic visits. Laboratory assessments may be part of the evaluation of medically attended AE evaluation and for all SAEs.

Upon ratification of the CTA, the site began pre-recruitment outreach efforts of potential volunteers within M3-WRA's database to ascertain "interest in general" in this study. Official recruitment which may include fliers, letters, telephone calls, etc. and specific recruitment of potential subjects who have previously participated in other clinical studies conducted at the site commenced only after formal IRB approval. Other forms and/or mechanisms of recruitment may also be used. The IRB will approved the recruitment process and all materials prior to use.
