The American Joint Replacement Registry AJRR is a not-for-profit organization focused on collecting data and improving quality for total hip and knee replacement surgeries across the United States. This observational study collects information to support quality improvement efforts involving hospitals, surgeons, insurers, and device manufacturers. The registry is supported by several professional societies including the American Academy of Orthopaedic Surgeons and the American Association of Hip and Knee Surgeons. Participants are individuals undergoing total joint arthroplasty. Data is collected observationally without specific treatment assignments or interventions. The registry gathers information from various sources to monitor outcomes and quality measures related to joint replacement surgeries. Participants health-related quality of life will be assessed at 12 months, along with specific measures like the Hip disability and Osteoarthritis Outcome Score - Joint Replacement HOOS, JR. The study collects ongoing data to support improvements in joint replacement care while allowing participants to continue with their usual medical care. Participation duration varies depending on individual surgery and follow-up schedules.

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 evaluating the Arthrex LoopLocTM device to see if it provides better capsular closure during hip arthroscopy compared to other treatments. The hip capsule is the tissue surrounding the hip joint that supports and stabilizes it, and it must be cut during hip arthroscopy. Traditional repair methods use knotted sutures that may cause irritation and scar tissue, potentially leading to pain. This study aims to compare outcomes between patients who receive the LoopLocTM device and those who do not after primary hip arthroscopy. Participants will either have the LoopLocTM device used for capsular closure during their hip arthroscopy or will undergo the procedure without this device as part of a control group. This prospective, multi-center study involves following patients for two years after surgery. Researchers will collect patient-reported and clinical outcomes to evaluate the feasibility and benefits of the knotless LoopLocTM device. During the two-year follow-up, patients will regularly visit their providers and researchers to assess outcomes such as the Modified Harris Hip Score, Non-Arthritic Hip Score, International Hip Outcome Tool, Hip Outcome Score Sports-Specific Subscale, Visual Analog Scale, and patient satisfaction. The study will monitor and compare these measures to determine if using the LoopLocTM device leads to improved results after hip arthroscopy.

Researchers are evaluating the safety and effectiveness of LY4268989 combined with mirikizumab compared to mirikizumab alone in adults with moderately to severely active ulcerative colitis. This phase 2 study aims to understand if the combination can better manage the condition. The study is sponsored by Eli Lilly and Company and involves a randomized, double-blind design with parallel groups. Participants receive either LY4268989 orally along with mirikizumab given intravenously and then subcutaneously, or mirikizumab with a placebo pill matching LY4268989. Responders to treatment will be re-randomized for a second study period. Treatment lasts approximately 104 weeks with up to 21 visits planned throughout the study. During the study, participants undergo assessments including clinical remission evaluation using the modified Mayo Score at weeks 12, 24, and 48, endoscopic improvement, and symptomatic remission measurements. Safety and response are closely monitored through scheduled visits. Overall participation lasts about 118 weeks, allowing researchers to gather long-term data on the treatments being studied.

Researchers are evaluating the safety and effectiveness of LY4268989 compared to a placebo in adults with moderately to severely active ulcerative colitis UC. The study focuses on participants with a diagnosis of UC for at least 3 months, confirmed by specific clinical and endoscopic criteria. This Phase 2 trial aims to better understand how LY4268989 may impact clinical remission and response in this patient group over a long-term period. Participants will receive either one of two doses of LY4268989 or a placebo, all administered orally. The study is randomized and double-blind, meaning neither participants nor researchers know who receives the active drug or placebo. The treatment period lasts up to approximately 108 weeks, excluding the screening phase, allowing for assessment of the drug over an extended time. During the study, participants will undergo regular evaluations including clinical assessments using the Modified Mayo Score to measure remission and response at multiple time points, including weeks 10 and 52. Researchers will also monitor symptomatic response and measure plasma concentrations of LY4268989. Safety and effectiveness will be tracked through these clinical and laboratory tests to understand the drugs impact on UC over the study duration.

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.
