The trial is being conducted at multiple centers with appropriate regulatory approvals in the United States (US), European Union (EU), and United Arab Emirates (UAE).</p><p>MVID is an ultrarare congenital enteropathy that causes intestinal failure (IF) from early childhood. Patients with MVID require lifelong and life-sustaining PS, consisting of total parenteral nutrition (TPN) with or without supplemental intravenous fluids, to provide the life-sustaining nutrients, electrolytes, and fluids for survival. Most MVID patients require daily PS, sometimes for 20 hours or more per day. While crucial for growth and survival for these patients, PS is associated with significant comorbidities, such as liver and kidney toxicities, metabolic complications, infections, and neurodevelopmental delays. There are currently no approved drug treatments for MVID. Incidence of MVID is extremely rare with a lethal natural history. The company estimates that oral liquid crofelemer treatment is being used as adjunctive therapy with PS in up to 4% of the prevalent global MVID patient population.</p><p>"In MVID, the therapeutic goal is to evaluate crofelemer's oral treatment to reduce the increased needs of PS to support growth, hydration, electrolytes, and nutritional requirements. This single-blind extension phase is an important clinical milestone for our pivotal randomized double-blind crossover clinical trial of crofelemer in the MVID trial to support the development and regulatory approval of the drug, intended to provide the longer-term safety and efficacy of crofelemer in MVID patients," said Dr. Pravin Chaturvedi, Chair of Scientific Advisory Board and Chief Scientific Officer of Napo Pharmaceuticals and Jaguar Health. "The decision to allow pediatric MVID patients to continue into the active treatment only single-blind extension phase after completion of the randomized double-blind crossover period is made by an independent data monitoring committee, which evaluates the safety data in a blinded setting."</p><p>"This continuation of this pivotal clinical trial of crofelemer for treatment of MVID, which has a lethal natural history without life-sustaining parenteral support, and the burden on children and families is a key milestone for our development and regulatory submission plans," added Lisa Conte, President and CEO of Jaguar. "Our team continues to evaluate expedited regulatory pathways to support the approval of crofelemer as a potential first-in-class adjunctive therapy, if approved, to decrease PS requirements and improve the quality of lives of these MVID pediatric patients."</p><p>As previously announced, Jaguar family company Napo plans to complete this pivotal, adequate and well-controlled clinical trial for the ultrarare pediatric MVID to support an NDA filing in mid-2027, subject to study completion and regulatory alignment. The Company will also include data from two additional MVID patients being evaluated under expanded access and open-label study protocols due to the ultrarare incidence and prevalence of MVID. Data from these two patients will be presented at the upcoming European Society of Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) annual meeting in June 2026. Jaguar has received orphan drug designation from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for crofelemer for MVID treatment.</p><p>Jaguar's MVID program is a part of the company's adult and pediatric intestinal failure (IF) development programs.
