상세 설명

이것은 다중 센터 무작위, 이중 맹검, 위약 대조, 병렬, 4군 연구입니다.

스크리닝 기간 동안 적격성을 충족한 후 피험자는 4개의 치료 부문 중 하나로 무작위 배정(1:1:1:1)됩니다.

  • 1군: 위약
  • 2군: 27mg 용량군
  • 3군: 54mg 투여군
  • 팔 4: 108mg 용량 팔 각 팔은 표: 투약 계획에 따라 맹검 2주 적정 기간 동안 고정 용량으로 적정되고, 이어서 약물에 대한 총 6주 동안 4주 고정 투여 기간이 이어집니다.

피험자는 고정 용량 기간이 끝날 때 연구 약물을 중단하고 추가 2주 동안 치료를 중단합니다.

언제라도 연구 제품의 영구적인 중단이 발생하는 경우, 피험자는 중단 및 안전 후속 방문을 위해 다시 방문해야 합니다. 그런 다음 심각한 부작용(SAE) 및 활력 상태에 대한 정보를 수집하기 위해 6주차에 전화로 연락을 취할 것입니다.

독립적인 데이터 안전 모니터링 위원회(DSMB)는 선택된 데이터를 주기적으로 검토합니다.

Relative Change From Baseline in Evaluating Respiratory Symptoms in Idiopathic Pulmonary Fibrosis (E-RS:IPF) Cough Subscale at Week 6
기간: Baseline, Week 6
The E-RS:IPF is a respiratory symptom subscale of the exacerbation of chronic pulmonary disease tool (EXACT) and consists of 11 items and was developed for use in IPF. The Cough subscale includes a single item (item 2: How often did you cough today?). The possible score range is 0 (not at all) to 4 (almost constantly). Higher scores indicate more severe symptoms. The relative change from baseline values is presented below. The relative change from baseline = [ (Post-baseline - Baseline) / Baseline] × 100. A positive change from baseline indicates worsening. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
Baseline, Week 6
Number of Participants Who Experienced at Least One Treatment Emergent Adverse Events (TEAEs)
기간: Up to Week 12
An adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A TEAE was defined as any AE that occurs after the first dose of study drug. TEAEs included both serious and non-serious TEAEs.
Up to Week 12
Relative Change From Baseline in 24-hour Cough Frequency at Week 6
기간: Baseline, Weeks 6
Relative change in 24-hour (combined daytime and nighttime) cough frequency (coughs per hour) from baseline was assessed. Assessment was done using objective digital cough monitoring.

Relative Change From Baseline in Awake Cough Frequency at Week 6
기간: Baseline, Week 6
Awake cough was defined as cough that occurs between the time that the participant is awaken 24 hours after the digital cough monitor was applied for use. Assessment was done using objective digital cough monitoring. The relative change from baseline = [ (Post-baseline - Baseline) / Baseline] × 100. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
Baseline, Week 6
Relative Change From Baseline in Sleep Cough Frequency at Week 6
기간: Baseline, Week 6
Sleep cough frequency was intended as the average coughs per hour while the participant was flagged as being asleep. Assessment was done using objective digital cough monitoring. Percent change in cough frequency (coughs per hour) from baseline was assessed. The relative change from baseline = [ (Post-baseline - Baseline) / Baseline] × 100. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

기간: Baseline, Week 6
The Total E-RS:IPF includes all 11 items from the scale and was developed for use in IPF. Items assignments to domains of the E-RS:IPF are as follows: the RS-Breathlessness domain (Items 7-11) has a score range of 0-23; the IPF-Chest domain (Items 1, 5, and 6) has a score range of 0-12; the IPF-Cough domain (Item 2) has a score range of 0-4; the IPF-Sputum domain (Items 3 and 4) has a score range of 0-8; and the E-RS:IPF total score (Items 1-11) ranges from 0-47.

Change From Baseline in Leicester Cough Questionnaire (LCQ) Total Score at Week 6
기간: Baseline, Week 6
LCQ is a self-reporting quality of life measure of chronic cough. It consists of 19 items with a 7-point Likert response scale ranging from 1 to 7. The responses are as follows: 1 = all of the time, 2 = most of the time, 3 = a good bit of the time, 4 = some of the time, 5 = a little of the time, 6 = hardly any of the time, and 7 = none of the time. Each item is designed to assess cough symptoms and the impact of cough across three main domains, physical (8 items), psychological (7 items), and social (4 items). Domain scores are calculated as the total score from items in the domain divided by the number of items in the domain and range from 1 to 7. The LCQ total score is calculated by summing the individual domain scores and ranges from 3 to 21, with higher scores indicating better health status. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

The L-IPF questionnaire is a 35-item questionnaire with two modules: symptoms (15 items) and impacts (20 items). The Impacts module yields a single Impacts score that is presented in this outcome measure. Each item's score ranges from 0-3. The score range for the L-IPF overall impacts raw sum score is 0-60, with higher scores indicating severe adverse impact. A negative change from Baseline indicates improvement. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

Change From Baseline in L-IPF Symptoms Domain Scores at Week 6
기간: Baseline, Week 6
The L-IPF questionnaire is a 35-item questionnaire with two modules: symptoms (15 items) and impacts (20 items). The L-IPF Symptoms module measures the various symptoms associated with IPF. The module contains 15 items that fall into 3 domains: Dyspnea, Cough, and Energy. Each item consists of a 0-3 score range. Dyspnea consists of 7 items and has a raw sum score range of 0-21 with higher scores indicating worsening dyspnea symptoms, Cough consists of 5 items and has a raw sum score range of 0-15 with higher scores indicating worsening cough symptoms, and Energy consists of 3 items and has a raw sum score range of 0-9 with higher scores indicating worsening energy. A negative change from Baseline indicates improvement. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

Number of Participants With Shift From Baseline in European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L™) at Week 6
기간: Baseline, Week 6
The EQ-5D-5L is a participant reported outcome and comprises of a descriptive system with 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). The recall period was the day that the questions were being completed. Each of the 5 dimensions in the descriptive system had 5 levels: 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, and 5 = extreme problems. Higher scores indicate worsening. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

Change From Baseline in Patient Global Impression of Severity (PGI-S) Cough Score at Week 6
기간: Baseline, Week 6
The PGI-S cough scale is a self-reported, single-item categorical scale used for assessing chronic cough. Participants rated the severity of their cough in the last week with a 4-point Likert scale (0-3: 0 = No Cough, 1 = Mild, 2 = Moderate, or 3 = Severe). Higher scores indicate worsening. A negative change from Baseline indicates improvement. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
