Trial Outcomes & Findings for Phase 3 Study of TAK-438 10 mg in the Treatment of Non-Erosive Gastroesophageal Reflux Disease (NERD) (NCT NCT02954848)

NCT ID: NCT02954848

Last Updated: 2019-08-02

Results Overview

Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. Reported data was the percentage of days for each group, calculated by the number of days without heartburn divided by the number of days of treatment period.

Participant Flow

Participants took part in the study at 44 investigative sites in Japan from 15 November 2016 to 26 February 2018.

Participants with a diagnosis of non-erosive gastroesophageal reflux disease (NERD) were enrolled and received one tablet of placebo orally, once daily in a run-in period. After that, the participants who met all the entry criteria were randomized in 1:1 ratio to receive TAK-438 10 mg or TAK-438 placebo-matching tablets.

PRIMARY outcome

Timeframe: Up to Week 4

Population: Full analysis set (FAS) included participants who were randomized and received at least one dose of the study drug.

Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. Reported data was the percentage of days for each group, calculated by the number of days without heartburn divided by the number of days of treatment period.

Timeframe: Day 0 to Day 24

Population: FAS included participants who were randomized and received at least one dose of the study drug.

Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. Cumulative rate of improvement was calculated as percentage of participants who experienced symptom improvement. Symptom improvement was defined as symptoms experienced on less than 2 days of the last 7 days. The cumulative data was collected between Day 0 and Day 24 and is reported for the following time points: Days 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, and 24.

Timeframe: Up to Week 4

Population: FAS included participants who were randomized and received at least one dose of the study drug.

Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. The severity of heartburn was calculated by the number of severity score in daily diaries.

Population: FAS included participants who were randomized and received at least one dose of the study drug. Number analyzed is the number of participants who had endoscopic findings.

Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, higher scores indicates greater severity. The percentage was calculated in each subgroup of the endoscopic findings where Grade N: normal mucosa; Grade M: minimal changes to the mucosa, such as erythema and/or whitish turbidity; Grade A: non-confluent mucosal breaks \<5mm in length; Grade B: non-confluent mucosal breaks ≥5mm in length; Grade C: confluent mucosal breaks \<75% circumferential; Grade D: confluent mucosal breaks \>75% circumferential.

SECONDARY outcome

Timeframe: Day 0 to Day 22

Population: FAS included participants who were randomized and received at least one dose of the study drug. Number analyzed is the number of participants who were evaluable for this outcome measure.

Participants recorded presence and severity (Without symptom \[No symptom:0, No hindrance to daily activities:1\], With symptom \[Mild:2, Moderate:3, Severe:4\]) of heartburn in participant diary. Score range was 0-4, higher score indicates greater severity. Cumulative rate of improvement calculated as percentage of participants who experienced symptom improvement. Response was evaluated per Criteria 1, i.e. Improved: participants experienced heartburn on less than 2 days of 7 days prior to Week 2 \[Day 8 through Day 14\]; Not improved: participants experienced heartburn on 2 days or more of 7 days prior to Week 2 \[Day 8 through Day 14\]. Modified LA classification Grade N indicates participants with normal mucosa and Grade M indicates participants with minimal changes to mucosa). Cumulative data collected between Day 0 and Day 22 and is reported for following time points: Days 0, 1, 2, 3, 4, 5, 6, 7, 8, 11, 15, 16, 17, 18, 20, 21 and 22.

Participants recorded the presence and severity (Without symptom \[No symptom: 0, No hindrance to daily activities: 1\], With symptom \[Mild: 2, Moderate: 3, Severe: 4\]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. The mean severity of heartburn was calculated in each subgroup of the response (improved or not improved) in the participants who had a medication history of any of acid suppressants. The acid suppressants include proton pump inhibitors \[PPIs\], histamine H2-receptor antagonists \[H2RAs\], or other agents \[anticholinergics or anti-gastrin drugs\].
