GroupInterventionDescription
NOC-110 6mgNOC-110NOC-110 (taplucainium) administered by daily dry powder inhalation. NOC-110 contains a dry powder lactose blend containing drug substance taplucainium administered using an available inhaler.
PlaceboPlaceboThe matching placebo contains inhalation grade lactose blended with arginine. The blend is taste masked to the active drug product to minimize unblinding due to taste differences. The matching placebo will be administered via the same inhaler.
NOC-110 1mgNOC-110NOC-110 (taplucainium) administered by daily dry powder inhalation. NOC-110 contains a dry powder lactose blend containing drug substance taplucainium administered using an available inhaler.
NOC-110 3mgNOC-110NOC-110 (taplucainium) administered by daily dry powder inhalation. NOC-110 contains a dry powder lactose blend containing drug substance taplucainium administered using an available inhaler.
Primary Outcome Measures
NameTimeMethod
Change in 24-hour Coughs per hour from BaselineBaseline to End of Treatment

Change in 24-hour Coughs per hour from Baseline will be based on VitaloJAK® Cough Counts. The VitaloJAK® is a 510(k)-cleared medical device consisting of a digital sound recorder with 2 microphones; a lapel air microphone attached to the participant's clothing and an adhesive chest wall microphone which is attached to the skin at the top of the sternum.

Secondary Outcome Measures
NameTimeMethod
Change in the Cough Severity Visual Analog Scale from BaselineBaseline to End of Treatment

Visual Analogue Scales for Cough Severity (CS-VAS) will be performed as outlined in the Schedule of Assessments. Participants rate the severity of their cough by marking on the horizontal line their cough severity, with the extreme left side of the line represents "no cough" and the extreme right side of the line representing "worst cough."

Change in Awake coughs per hour from BaselineBaseline to End of Treatment

Change in Awake coughs per hour from Baseline will be based on VitaloJAK® Cough Counts. The VitaloJAK® is a 510(k)-cleared medical device consisting of a digital sound recorder with 2 microphones; a lapel air microphone attached to the participant's clothing and an adhesive chest wall microphone which is attached to the skin at the top of the sternum.

Change in the Leicester Cough Questionnaire from BaselineBaseline to End of Treatment

Leicester Cough Questionnaire (LCQ) is a validated cough-specific quality of life measure that evaluates the impact of cough across 3 domains: physical, psychological, and social. The LCQ is a 19-item questionnaire with each item scored using a 7-point Likert scale ranging from 1 = all the time to 7=none of the time. The total severity score ranges from 3-21, with a lower score indicating greater impairment of health status due to cough.

Change in the Urge to Cough Visual Analog Scale from BaselineBaseline to End of Treatment

Urge to Cough Analogue Scales for Cough Severity (UC-VAS) will be performed as outlined in the Schedule of Assessments. Participants rate the severity of their cough by marking on the horizontal line their cough severity, with the extreme left side of the line represents "no cough" and the extreme right side of the line representing "worst cough."

Patient Global Impressions of Improvement scoreEnd of Treatment

Patient Global Impressions of Improvement (PGI-I) is used to assess improvement or worsening of the Participants status in relation to the therapeutic area of interest. The main purpose of the scale is to quantify the extent to which the participant has improved or deteriorated over time. The PGI-I is a 7-point Likert scale ranging from 1=Very Much Better to 7=Very Much Worse.
