Study Summary

This trial is testing a new drug to see if it can help people with early signs of MIS-C who are at high risk of progression. The drug is given four times a day.

Who is the study for?
This trial is for children and young adults from 1 month to under 21 years old with MIS-C related to COVID-19. Participants must show early signs of MIS-C, have a fever, inflammation markers in the blood, severe illness needing hospitalization affecting multiple organs including the gut, and no other diagnosis that explains their symptoms. They also need proof of current or recent SARS-CoV-2 infection.Check my eligibility
What is being tested?
The study tests AT1001 (Larazotide Acetate) against a placebo given four times daily alongside standard care for MIS-C. The goal is to see if AT1001 can help pediatric patients who are at high risk of worsening symptoms due to early signs of MIS-C.See study design
What are the potential side effects?
Specific side effects for Larazotide Acetate aren't detailed here but generally could include digestive issues since it's taken orally, potential allergic reactions, or other common drug-related side effects.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Determine proportion of participants with improvement in MIS-C related GI symptoms and no progression of disease
Evaluate the efficacy and safety of AT1001 versus placebo on mitigating symptoms of MIS-C
Secondary outcome measures
Determine the impact of AT1001 on change from baseline in additional organ system(s) involvement during acute presentation/hospitalization, as identified by clinical assessment and clinical laboratory tests.
Determine the impact of AT1001 on change from baseline in levels of IgM, IgG, and IgA antibodies against SARS CoV-2.
Determine the impact of AT1001 on change from baseline in levels of inflammatory markers (CRP, d-dimer, ferritin).
