Researchers are evaluating efruxifermin EFX in adults with non-cirrhotic nonalcoholic steatohepatitis NASH or metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage 2 or 3. This Phase 3, multi-center, randomized, double-blind, placebo-controlled study aims to assess the safety and efficacy of EFX compared with placebo. The trial includes about 1,650 participants divided into two cohorts based on liver biopsy characteristics and fibrosis stage. Participants will be randomly assigned to one of three groups EFX 28 mg, EFX 50 mg, or placebo, each given as a weekly subcutaneous injection. Cohort 1 will be evaluated over 52 weeks for histologic efficacy endpoints, while Cohort 2 will have assessments over 96 weeks. After these periods, participants may continue long-term treatment and clinical follow-up for up to approximately 240 weeks total. A follow-up visit will occur about 30 days after the last dose. During the study, participants will undergo liver biopsies, blood tests, and non-invasive assessments such as FibroScan and Enhanced Liver Fibrosis ELF score to monitor liver health and fibrosis. Researchers will track liver-related clinical outcomes, including liver events and survival, as well as safety and tolerability of the treatment. Participants who stop the study drug may still continue with scheduled assessments to support long-term safety and efficacy evaluations.

Researchers are evaluating the efficacy and safety of two different dose regimens of pegozafermin compared to a placebo in adults with metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage F2 or F3. This Phase 3 study aims to better understand how pegozafermin may impact liver fibrosis and steatohepatitis in this population. Participants will receive subcutaneous injections of either one of two pegozafermin regimens or a matched placebo. These treatments are given in parallel groups, and participants are randomly assigned to one of the study groups. The study compares the effects of pegozafermin on liver fibrosis and steatohepatitis over a treatment period that includes evaluations up to 52 weeks and monitoring for disease progression up to 5 years. During the study, participants will be monitored through biopsies and blood tests to assess liver fibrosis improvement, resolution of steatohepatitis, changes in liver enzyme levels, and enhanced liver fibrosis scores. Safety and disease progression are also tracked throughout the study period. The total participation duration includes treatment and long-term observation to evaluate outcomes and any potential changes in liver health.

Researchers are evaluating the effects of two oral drugs, ECC4703 and ECC0509, alone and in combination, on reducing liver fat in adults with presumed Metabolic Dysfunction-associated Steatohepatitis MASH. This phase 2a trial compares low and high doses of each drug and their combination with a placebo to assess changes in liver fat using MRI at 12 weeks. Participants are randomly assigned to one of several groups receiving either placebo, low or high doses of ECC4703, low or high doses of ECC0509, or a combination of high doses of both drugs. Each treatment is given as oral capsules. The main study period lasts 12 weeks during which participants take the assigned capsules and undergo evaluations. During the trial, participants will have multiple assessments including MRI scans to measure liver fat, blood tests to monitor liver enzymes and metabolic markers, and quality of life questionnaires. Drug levels in the blood will be measured at several time points. The study measures liver fat reduction primarily at 12 weeks and monitors safety and various biochemical markers throughout the period.

Researchers are evaluating the efficacy and safety of pegozafermin in adults with compensated cirrhosis caused by metabolic dysfunction-associated steatohepatitis MASH, previously known as nonalcoholic steatohepatitis NASH. This study focuses on participants with biopsy-confirmed advanced liver fibrosis stage F4 due to MASH. The research aims to understand how pegozafermin affects liver health over time compared to a placebo. Participants will receive either pegozafermin or a matched placebo through subcutaneous injections. The study follows a randomized, parallel design with quadruple masking to ensure unbiased results. The treatment period extends up to 24 months, with additional long-term follow-up lasting up to five years to assess disease progression and liver fibrosis regression. During the study, participants will undergo various assessments including measurements of liver fibrosis, disease progression through clinical events, and liver function tests such as alanine aminotransferase ALT levels. Tools like Enhanced Liver Fibrosis ELF score and FibroScan Vibration-controlled Transient Elastography VCTE will be used to monitor liver condition up to 60 months. Safety and efficacy will be closely monitored throughout the study period, which may last up to seven years in total.

Researchers are investigating the efficacy and safety of duvakitug in people with moderately to severely active Crohns Disease in a multinational, multicenter, randomized, double-blind, placebo-controlled Phase 3 study. The trial includes three sub-studies aiming to evaluate duvakitugs effects compared to placebo during induction treatment phases, focusing on clinical remission and endoscopic response at 12 weeks. Participants receive subcutaneous injections of duvakitug or placebo following the study protocol. The study duration can be up to 35 weeks, including a screening period of up to 5 weeks, followed by a 12-week induction phase in either Sub-Study 1 open-label, Sub-Study 2 pivotal induction, or Sub-Study 3 extended induction for non-responders. A 6-week follow-up period applies to participants not entering the maintenance study. Throughout the trial, participants undergo scheduled visits for assessments including clinical remission based on Crohns Disease Activity Index and endoscopic scores. Safety is monitored with reports of adverse events and serum drug levels. Up to 8 to 15 visits are planned depending on the sub-study, with follow-up continuing for 45 days after the last dose for those not moving to maintenance treatment.

Researchers are evaluating the efficacy and safety of duvakitug, a drug given by subcutaneous injection, in people with moderately to severely active Ulcerative Colitis UC. This Phase 3 randomized, double-blind, placebo-controlled study includes participants aged 16 to 80 years and aims to assess clinical remission and other health improvements over a series of treatment periods. The study lasts up to 35 weeks and includes a screening period followed by three possible sub-studies a 12-week open-label induction, a 12-week pivotal induction, and a 12-week extended induction for those who do not respond initially. Participants receive injections of either duvakitug at one of two doses or placebo according to the study protocol, with up to 15 visits scheduled for those in extended induction. During the study, participants will undergo assessments including clinical remission rates at week 12, endoscopic and histological improvements, symptom tracking, quality of life questionnaires, and safety monitoring for adverse events. Follow-up visits occur up to 45 days after the last dose for those not continuing in the maintenance study. Researchers will also measure drug levels and immune responses over the study period to better understand treatment effects.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.
