About
The purpose of this study is to assess the efficacy and safety of treatment with 2 dose levels of TAK-906 in adult participants with gastroparesis compared with placebo during 12 weeks of treatment.
Full description
The drug being tested in this study is called TAK-906. TAK-906 is being tested to treat people who have symptomatic idiopathic or diabetic gastroparesis.
The study will enroll approximately 205 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the three treatment groups (in 1:1:1:1 ratio) which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):
Prior to Amendment 8, participants were randomized to receive TAK-906 5 mg. After implementation of Amendment 8, participants will not be further randomized to this dose arm. All participants will be asked to take one capsule twice daily, at approximately the same time each day throughout the study.
This multi-center trial will be conducted worldwide. The overall study duration is approximately 17 weeks. Participants will make multiple visits to the clinic, and will be contacted by telephone 30 days after receiving their last dose of study drug for a follow-up assessment.

Inclusion criteria
Should have experienced symptoms of gastroparesis (e.g., postprandial fullness, nausea, vomiting, upper abdominal pain, and early satiety for at least 3 months before screening as assessed by a physician.
Must have confirmed delayed gastric emptying by meeting 1 of the following criteria:
Must have an average composite ANMS GCSI-DD symptom score ≥2 during the 7 days before randomization. The predominant symptom experienced by participants must not be abdominal pain.
Must experience nausea: nausea subscale (of ANMS GCSI-DD) symptom score ≥2 at least 4 of 7 days or an average nausea subscale symptom score ≥2 during the 7 days before randomization. Nausea symptoms must not be attributable to a central disorder (e.g. motion sickness, glaucoma, menstrual cycles, migraine headache).
Has a body mass index (BMI) of ≥18 to ≤40 kg/m^2 inclusive.
Participant with diabetes mellitus must have glycosylated hemoglobin (HbA1c) ≤11% at screening and before randomization.
Absence of gastric outlet obstruction confirmed by upper GI, computed tomography or endoscopy.
Exclusion criteria
Known secondary causes of gastroparesis including but not limited to Parkinson disease, cancer, viral illness, or connective tissue diseases.
Predominant gastroparetic symptom is epigastric pain, diffuse abdominal pain, or pain associated with bowel movement.
Is taking medications that affect gastric emptying including opioids, glucagon-like peptide-1 analogs (e.g., exenatide, liraglutide), amylin analogs (e.g., pramlintide), and cannabinoids.
Prior history of gastric surgery, including but not limited to gastrectomy, gastric bypass, gastric banding, bariatric surgery, pyloroplasty, vagotomy, or fundoplication, which has manipulated the natural anatomy of the stomach.
History of intra-pyloric botulinum toxin injection within 3 months of Screening or currently has functioning implantable electric stimulator.
Nasogastric, percutaneous endoscopic gastrostomy, or percutaneous endoscopic jejunostomy feeding tube or inpatient hospitalization for gastroparesis within 2 weeks before the Screening Visit.
Required parenteral nutrition for treatment of gastroparesis within 2 months before the Screening Visit.
Previous diagnosis of gastric bezoar (the presence of retained liquid, bile, or small amounts of poorly organized food residue is permitted).
Poor control of diabetes within 30 days prior to randomization, including diabetic ketoacidosis, hypoglycemia requiring medical intervention, admission for control of diabetes or diabetic complications.
Elevated serum prolactin (>upper limit of normal [ULN]) at Screening.
Has concurrent hypogonadism, current clinically significant menstrual abnormalities, such as amenorrhea or oligomenorrhea, or other clinical features of hyperprolactinemia such as galactorrhea or gynecomastia.
Has acute or chronic liver disease meeting any of the criteria described below:
Has renal impairment, defined as a lower limit of (estimated glomerular filtration rate [eGFR]) <30 mL/min at screening visit.
Has active neoplastic disease or history of neoplastic disease within 5 years of screening visit (except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the uterine cervix that has been definitively treated with standard of care approaches).
Uncontrolled or poorly controlled medical or psychiatric comorbidities which might affect their ability to participate in the study.
Has known COVID-19 infection, or suspected COVID-19 infection (as assessed by the investigator).
