Condition/Disease

Erosive Esophagitis

Objectives

Primary Objectives: To demonstrate the non-inferior efficacy of TAK-438 versus Lansoprazole in the healing of subjects with erosive esophagitis classified as LA classification grades A to D during the 8-week treatment. Secondary Objectives: To compare the efficacy of TAK-438 versus Lansoprazole in the healing of subjects with erosive esophagitis classified as LA classification grades A to D during the 2-week treatment. To compare the efficacy of TAK-438 versus Lansoprazole in the healing of subjects with erosive esophagitis classified as LA classification grades A to D during the 4-week treatment. To compare the safety of TAK-438 versus Lansoprazole in subjects with erosive esophagitis classified as LA classification grades A to D. Additional Objectives: To compare the difference of TAK-438 versus Lansoprazole in the subjective symptoms of erosive esophagitis and health-related quality of life measures. To compare the difference of TAK-438 versus Lansoprazole in the percentage of days without rescue medication during the treatment phase.

Endpoints

Efficacy:
The primary efficacy endpoint of this study is the rate of endoscopic healing of erosive esophagitis during the 8-week treatment phase.
The secondary efficacy endpoints of this study are
 the rate of endoscopic healing of erosive esophagitis during the 2-week treatment
 the rate of endoscopic healing of erosive esophagitis during the 4-week treatment.
Other efficacy endpoints include subjective symptoms of erosive esophagitis as recorded in subject diaries (e.g. heartburn, gastric acid regurgitation), health-related quality of life measures and percentage of days without using rescue medication.
Safety:
The safety endpoints of this study include adverse events, laboratory test values, ECG, vital signs, serum gastrin and pepsinogen I/II values.

Inclution Criteria

Subject eligibility is determined according to the following criteria:
1. In the opinion of the investigator, the subject is capable of understanding and complying with protocol requirements.
2. The subject or, when applicable, the subject’s legally acceptable representative signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
3. The subject has been confirmed in an endoscopy to have erosive esophagitis, i.e. the LA classification grades A to D within 7 days of the start of the Day 1 (Visit 2).
Note: The recruitment goal is to ensure that those with LA classification grade C/D will account for more than 30% of all subjects enrolled (144/480), with no further recruitment of those with grade A/B considered when they account for more than 70% (336/480) of all subjects.
4. The subject is aged 18 years old or older (or the local age of consent if that is older), male or female, at the time of signing an informed consent, and is being treated on an outpatient basis for erosive esophagitis, including those admitted temporarily for examination.
5. A female subject of childbearing potential* who is sexually active with a nonsterilized* male partner agrees to use routinely adequate contraception* from signing of informed consent throughout the duration of the study and for 4 weeks after last dose of study medication.
*Definitions and acceptable methods of contraception are defined in Section 9.1.9 Contraception and Pregnancy Avoidance Procedure and reporting responsibilities are defined in Section 9.1.10 Pregnancy.

Exclusion Criteria

Any subject who meets any of the following criteria will not qualify for entry into the study:
1.The subject has received any investigational compound within 84 days prior to the start of the Observation phase.
2.The subject has received TAK-438 in a previous clinical study or as a therapeutic agent.
3.The subject is an immediate family member, study site employee, or is in a dependant relationship with a study site employee who is involved in conduct of this study (e.g., spouse, parent, child, sibling) or may consent under duress.
4.The subject has, in the judgment of the investigator, clinically significant abnormal hematological parameters of hemoglobin, hematocrit, or erythrocytes at Screening.
5.The subject has a history or clinical manifestations of serious CNS, cardiovascular, pulmonary, hepatic, renal, metabolic, gastrointestinal, urological, endocrine or hematological disease.
6.The subject has a history of hypersensitivity or allergies to TAK-438 (including its excipients*) or to proton pump inhibitors (PPIs).
*D-mannitol, crystalline cellulose, hydroxypropyl cellulose, fumaric acid, croscarmellose sodium, magnesium stearate, hypromellose, macrogol 6000, titanium oxide, yellow iron sesquioxide and iron sesquioxide.
7.The subject has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse within 1 year prior to the Observation Phase (Visit 1).
8.The subject is required to take excluded medications listed in Section 7.3.
9.If female, the subject is pregnant or lactating or intending to become pregnant before, during, or within 1 month after participating in this study; or intending to donate ova during such time period.
10.The subject has participated in another clinical study within the past 30 days from Visit 1.
11.The subject has co-morbidities that could affect the esophagus (eosinophilic esophagitis, esophageal varices, scleroderma, viral or fungal infection, esophageal strictures), a history of radiotherapy or cryotherapy for the esophagus; those with corrosive or physiochemical injury (with the possible inclusion in the study of those with Schatzki’s ring or Barrett’s esophagus).
12.The subject has a history of surgical procedures that may affect the esophagus (eg, fundoplication and mechanical dilatation for esophageal strictures excluding Schatzki’s ring) or a history of gastric or duodenal surgery excluding endoscopic removal of benign polyps.
13.The subject developed acute upper gastrointestinal bleeding, gastric ulcer (a mucosal defect with white coating) or duodenal ulcer (a mucosal defect with white coating), within 30 days before the start of the Observation Phase (Visit 1) (with the possible inclusion of those with gastric or duodenal erosion). The subjects requiring NSAIDs or aspirin treatment along with the concomitant PPI therapy to prevent GI bleeding should not be enrolled.
14.The subject has Zollinger-Ellison syndrome or gastric acid hypersecretion or a history of gastric acid hypersecretion.
15.The subject is scheduled for surgery that requires hospitalization or requires surgical treatment during his/her participation in the study.
16.The subject has a history of malignancy or was treated for malignancy within 5 years before the start of the Observation Phase (Visit 1) (the subject may be included in the study if he/she has cured cutaneous basal cell carcinoma or cervical carcinoma in situ).
17.The subject has acquired immunodeficiency syndrome (AIDS) or hepatitis, including hepatitis virus carriers: HBs-antigen positive or HCV-antibody-positive (the subject may be included in the study if he/she is HCV-antigen or HCV-RNA-negative).
