A Study to Evaluate the Efficacy and Safety of CIN-102 (Deudomperidone) in Adults With Diabetic Gastroparesis

The goal of this clinical trial is to evaluate if the study drug CIN-102 (deudomperidone) can help reduce the symptoms associated with diabetic gastroparesis in adult patients.

The main questions it aims to answer are:

* To evaluate the efficacy of CIN-102 on symptoms of gastroparesis when given to patients with diabetic gastroparesis compared to a placebo * To evaluate the safety and tolerability of CIN-102 when given to patients with diabetic gastroparesis compared to a placebo

Participants will go through the following schedule:

* Screening period (1-2 visits) * Lead-in period (1 visit)

* Will complete a Gastric Emptying Breath Test (GEBT) * Will complete daily diary and other Patient Reported Outcomes (PROs) as described in the protocol to assess eligibility for continued study participation * 12-week treatment period (7 visits)

* Study drug taken twice daily by mouth * Will complete daily diaries and other PROs as described in protocol * 1 week follow-up (1 visit)

Researchers will compare the effects of the following treatments:

* Drug- CIN-102 Dose 15 mg or 10 mg * Drug- Placebo

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Is a male or female ≥18 years of age;
  • Has a diagnosis of Type 1 or Type 2 diabetes, according to the American Diabetes Association criteria;
  • Has a current diagnosis of diabetic gastroparesis defined by the following:
  • Persistent gastrointestinal symptoms that in the opinion of the Investigator are consistent with gastroparesis within 6 months prior to Screening; AND
  • Documented delayed gastric emptying as determined by gastric emptying breath test (GEBT), scintigraphy, or manometry.
  • Body mass index (BMI) between 18 and 49 kg/m2, inclusive;
  • Glycosylated hemoglobin (HbA1c) level <10% at Screening;
  • If receiving treatment with GLP-1RA, may be considered for the study if all of the following criteria are satisfied:
  • The GLP-1 RA has been prescribed for the management of diabetes and not specifically for weight loss/weight management;
  • Has been on a stable dose of GLP-1RA for a minimum of 3 months before Screening and is anticipated to sustain the same dose during GEBT and throughout the study;
  • Is tolerating the GLP-1RA well based on Investigator's judgment;
  • None of the study-qualifying signs/symptoms of gastroparesis are solely attributable to the use of GLP-1RA; and
  • The symptoms of gastroparesis preceded the initiation of GLP-1RA therapy.
  • Willing to washout from ongoing treatment for gastroparesis.

Key Exclusion Criteria:

  • Has known cause of gastroparesis other than diabetes (eg, idiopathic gastroparesis and/or gastroparesis attributed to surgery, viral illness, cancer, scleroderma, or other neurologic disorder);
  • Has been hospitalized within 3 months prior to Visit 1 for diabetic gastroparesis and/or diabetic ketoacidosis and/or malnutrition;
  • History or evidence of clinically significant arrhythmia;
  • History of pyloroplasty, pyloromyotomy, or gastric peroral endoscopic myotomy, fundoplication, gastrectomy, vagotomy, or bariatric surgery;
  • Currently receiving parenteral feeding or presence of a nasogastric or other enteral tube for feeding or decompression;
  • Pyloric injection of botulinum toxin within 6 months of Screening;
  • Positive test for drugs of abuse;
  • Has a known allergy to eggs or spirulina;
  • Females who are pregnant, breastfeeding, or planning to become pregnant or breastfeed during the study.

Treatment and study plan

CIN-102 Dose 15mg or 10mg

Drug

2 capsules twice daily for 12 weeks

Placebo

Drug

2 capsules twice daily for 12 weeks

Primary outcomes

  1. Effect of CIN-102 to significantly decrease gastroparesis-related symptoms as compared to baseline based on the composite of the average ANMS GCSI-DD Nausea Sub-Scale and Vomiting Scores

    Time frame: Over the last 2 weeks of the 12-week Treatment Period as compared to baseline

    The American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index Daily Diary (ANMS GCSI-DD) Nausea Subscale scores and the Vomiting subscale scores will be averaged into a single value that ranges 0-4 (0 for no symptom and 4 for very severe)

Secondary outcomes

  1. Incidence of clinically significant changes, in the Investigator's opinion, in laboratory parameters, physical examination findings, 12-lead ECG parameters, weight measurement.

    Time frame: Over the 12-week Treatment Period
