AT1001 for the Treatment of Long COVID

Phase 2a Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Evaluate the Safety and Efficacy of Larazotide (AT1001) for the Treatment of Long COVID in Children and Adults


Sponsor

Massachusetts General Hospital

Enrollment

150 participants

Start Date

May 31, 2023

Study Type

INTERVENTIONAL

Conditions

Summary

The primary objective of this study is to evaluate the safety and efficacy of Larazotide (AT1001) versus placebo in children and adults 7 to ≤50 years of age who present with symptoms of Long COVID in the presence of SARS-CoV-2 antigenemia. AT1001 (n=100) or placebo (n=50) will be administered orally four times a day (QID) for 21 days.


Eligibility

Min Age: 7 YearsMax Age: 50 Years

Inclusion Criteria3

  • Age 7 to ≤50 years
  • History of SARS-CoV-2 infection, documented by positive PCR and/or antigen test
  • Ongoing, worsening, new, or recurrent symptoms present ≥4 weeks after SARS-CoV-2 infection.Symptoms include but are not limited to fatigue, malaise, headache, cognitive impairment, neuropsychiatric symptoms, decreased exercise tolerance, post exertional malaise, dyspnea, cough, chest pain, palpitations, tachycardia, gastrointestinal symptoms, musculoskeletal symptoms, fever, lightheadedness, insomnia and other sleep disturbances, anosmia or dysgeusia, pain, paresthesia, menstrual cycle irregularities, erectile dysfunction.

Exclusion Criteria11

  • Age ≤6 years or >50 years at time of enrollment
  • Pregnancy and/or lactation
  • Female participant of childbearing age unwilling to use an acceptable method of birth control for the duration of the study
  • Inability to tolerate drug
  • Unstable medical conditions or significant co-morbid disease that, by the investigator's determination would make the participant unsuitable for enrollment
  • Participation in any other clinical investigation using an experimental drug within 30 days prior to screening
  • Intent to participate in another clinical study while participating in this clinical trial
  • Blood/plasma donation and or blood loss greater than 400 mL within 90 days, or greater than 200 mL within 30 days prior to screening
  • Known hypersensitivity to any of the formulation components of AT1001.
  • Abnormal baseline liver function as indicated by AST or ALT ≥3 times the upper limit of normal (ULN), or total bilirubin ≥2x ULN for age
  • Abnormal baseline renal function, defined as glomerular filtration rate ≤50 mL/min/1.73m2

Interventions

DRUGLarazotide Acetate

AT1001 (Larazotide) is a locally acting, non-systemic, octapeptide inhibitor of the zonulin receptor that has shown efficacy in a large variety of animal models of inflammation. The effectiveness of AT1001 in controlling paracellular permeability as a tight junction regulator has been widely demonstrated in animal models both in vitro and in vivo. In MIS-C, prolonged presence of SARS-CoV-2 in the GI tract leads to release of zonulin, a biomarker of intestinal permeability, with subsequent trafficking of SARS-CoV-2 antigens into the bloodstream, leading to hyperinflammation (Yonker, et. al. 2021). Five children treated with AT1001 (through an Emergency Investigational New Drug request authorized by the FDA) displayed a decrease in plasma SARS-CoV-2 Spike antigen levels, inflammatory markers, and symptom improvement superior to that achieved with the current standard of treatment for MIS-C (ie. immunoglobulin, systemic steroids) (Yonker, et. al. 2021) (Yonker, et. al. 2022)

DRUGPlacebo

Matching placebo will be administered orally four times a day (QID) to participants in the placebo arm.
