    1. 3 month past or current history of symptoms of gastroparesis (e.g. nausea, vomiting, bloating, abdominal pain, or feeling full earlier than normal after eating)
    2. Screening or historical scintigraphy (3 years prior to screening) with > 20% of solid contents retained at 4 hours.
  • BMI >= 20.0 and \< = 50.0 kg/m2

Exclusion criteria

Exclusion Criteria:

  • Participants on prokinetic therapy should have these medications withdrawn at least 7 days prior to any study scintigraphy exam and at least 7 days prior to the first dose through Day 15 of treatment.
  • Participants with any active prokinetic device are excluded, unless device is turned off for at least 7 days prior to any study scintigraphy exam and at least 7 days prior to the first dose through Day 15 of treatment.
  • Participants who are currently participating in or have participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention.

What researchers measure

Primary outcomes

  1. Frequency of clinically significant laboratory abnormalities

    Time frame: Day 38

  2. Frequency of clinically significant vital signs

    Time frame: Day 38

  3. Frequency of clinically significant ECGs

    Time frame: Day 38

Secondary outcomes

  1. Nimacimab serum concentration

    Area under the plasma concentration versus time curve (AUC)

    Time frame: Day 3, Day 8, Day 10, Day 38

Other outcomes

  1. Measure rate of gastric emptying after ingestion of a radio-labeled meal as measured by gamma scans (scintigraphy) at 0, 0.5, 1, 2, 3, and 4 hours post meal

    Time frame: Baseline, Day 10

  2. Gastric emptying half-time as measured by gamma scans (scintigraphy) after ingestion of a radio-labeled meal.

    Half time (t1/2) of gastric emptying (GE) of solids is the time for half of the ingested solids or liquids to leave the stomach.

    Time frame: Baseline, Day 10

  3. Change from baseline in American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index Daily Diary (GCSI-DD) Composite Score at 15 days

    The ANMS GCSI-DD composite score includes score of nausea, early satiety, upper abdominal pain and postprandial fullness. The severity scores of these symptoms range from 0 ( none) to 4 (very severe).

    Time frame: Baseline and 15 days
