Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests an experimental drug called NSI-8226 (solrikitug) in adults with eosinophilic esophagitis, a condition that causes trouble swallowing due to inflamed esophagus. About 184 participants will receive either the drug or a placebo to see if it reduces inflammation and improves swallowing symptoms. The goal is to find a safer, more effective treatment for this chronic condition.

Key inclusion criteria Part A * Participant must be 18 to 75 years of age inclusive, at the time of signing the informed consent. * Established diagnosis of EoE with a previous EGD and esophageal biopsy confirming diagnosis of EoE. * Participants who have symptomatic EoE as defined by a history of on average at least 2 episodes of dysphagia per week in the 4 weeks prior to Screening. * Must remain on a stabilized diet for at least 8 weeks prior to Visit 1 and during the course of the study. * May be on any background PPI and/or STC, during the course of the study, as long as background medications have been stable for at least 8 weeks prior to the Screening and must agree to no changes to background medication or dosage unless medically indicated. * Discontinuation of any marketed investigational drug or biologic (monoclonal or polyclonal antibody) within 30 days or 5 half-lives prior to screening, whichever is longer. * Participants should have previously documented standard of care treatment, which could include PPI and/or STC and/or diet. Key exclusion criteria Part A * Female participant who is pregnant or breastfeeding. * Have a history or presence of any other gastrointestinal disorders such as active Helicobacter pylori infection, history of achalasia, hyper eosinophilic syndrome and eosinophilic granulomatosis with polyangiitis, esophageal varices, Crohn's disease, ulcerative colitis, inflammatory bowel disease, celiac disease, eosinophilic enteritis, gastritis, colitis, diverticulitis, irritable bowel syndrome, or other clinically significant gastrointestinal conditions as per Investigator discretion. * Esophageal stricture that prevents the easy passage of a standard endoscope or any critical esophageal stricture that requires dilation at screening. * Esophageal dilation performed within 8 weeks prior to screening. * Participant has a known hypersensitivity to any component of the formulation of solrikitug, including any of the excipients, or a history of anaphylactic reaction to any therapeutic monoclonal antibody. Part B * Participants who, during Part A, developed a serious adverse event (SAE) and/or adverse event (AE) deemed related to study drug, which in the opinion of the investigator could indicate that continued treatment with study drug may present and unreasonable risk to the participant. * Participants who became pregnant during Part A. * Participants who are prematurely discontinued from study drug due to AE (patients who are prematurely discontinued from study drug due to lack of efficacy are eligible to enter Part B). * Patients who did not undergo endoscopy with biopsies prior to receiving rescue treatment.
