Researchers are assessing the safety and effects of Ritlecitinib, a study medicine, for treating hidradenitis suppurativa (HS), a condition causing long-lasting, painful red skin lumps. This phase 2 study focuses on adults with moderate to severe HS who have not responded well to or cannot tolerate antibiotics. The goal is to compare experiences and outcomes between those receiving Ritlecitinib and those receiving a placebo. Participants will be randomly assigned to take either Ritlecitinib or a placebo pill once daily at home. The treatment involves an initial loading dose of Ritlecitinib for 8 weeks, followed by an 8-week maintenance dose, totaling 16 weeks of treatment. The placebo group will receive a matching pill with no active medicine. Over approximately 24 weeks, including screening and follow-up, participants will attend around 10 clinic visits for health evaluations, including physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. They will also track their medication intake and HS symptoms daily using an electronic diary on a mobile phone. The study will measure how many patients achieve at least a 50% improvement in HS symptoms by week 16 to evaluate treatment response and safety.

Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation (CIC) in this 26-week phase 3 study. The study is randomized, double-blind, and placebo-controlled, involving multiple centers. It aims to compare three doses of tenapanor (5 mg, 25 mg, and 50 mg taken twice daily) against a placebo, with a focus on improving spontaneous bowel movements. Participants will first undergo a 2-week screening where their eligibility is assessed through medical history, physical exams, lab tests, ECG, and self-reported constipation symptoms using an electronic diary (eDiary). Eligible patients will then be randomly assigned to receive one of the three doses of tenapanor or placebo twice daily for 26 weeks. During this treatment period, patients will continue daily and weekly symptom reporting via the eDiary and attend regular safety visits at weeks 2, 4, 8, 12, 16, 20, and 26. After completing the 26-week treatment, patients enter a 4-week treatment-free safety follow-up period to monitor any adverse events. A final visit occurs at the end of this follow-up to assess safety. The main outcome measured is the durable complete spontaneous bowel movements response over 12 weeks. Overall, the study involves careful monitoring of symptoms, safety, and treatment effects over approximately 32 weeks.

Researchers are studying a treatment called MK-2214 to see if it can slow certain brain changes in people with early Alzheimer's disease (AD). AD is a form of dementia that causes memory loss, difficulties with communication, and challenges in decision-making, which affect daily activities. The study aims to find out if MK-2214 can slow the spread of tau protein in the brain compared to a placebo and to assess the safety and tolerability of MK-2214. Participants will receive either MK-2214 or a placebo through an intravenous (IV) infusion. The study is designed as a phase 2, randomized, placebo-controlled, double-blind trial with parallel groups. The treatment period lasts up to about 23 months, during which participants will receive infusions as scheduled. The placebo looks like the study treatment but contains no active drug, helping researchers understand the treatment's effects. Throughout the study, participants will be monitored for changes in tau protein levels in the brain using PET scans and for any adverse events or side effects. Researchers will track the number of participants experiencing adverse events and those who stop treatment because of them, with safety follow-up lasting up to approximately 26 months. Participants will also undergo brain imaging such as CT, PET, or MRI scans. The study involves regular assessments to measure the treatment's impact and ensure participant safety over the study duration.

Researchers are evaluating intravitreal EYE103 in participants with neovascular age-related macular degeneration (NVAMD) or macular edema following branch retinal vein occlusion (BRVO). This Phase 2, randomized, dose-masked study includes four patient cohorts: treatment-naive NVAMD participants, incomplete responder (IR) NVAMD participants as monotherapy, IR NVAMD participants receiving EYE103 combined with aflibercept 2.0 mg, and treatment-naive BRVO participants. The study aims to assess safety and efficacy of different doses of EYE103 in these conditions. Participants in each cohort will be randomly assigned to receive either a low or high dose of EYE103 via intravitreal injection. All participants will receive three injections spaced four weeks apart. IR NVAMD participants in the combination therapy cohort will also receive an injection of aflibercept 2.0 mg on Day 1. The timing of enrollment into each cohort is determined by the Sponsor. Participants will undergo safety and efficacy assessments at each injection visit, with some cohorts returning two weeks after injections for further evaluations. Assessments include measuring best-corrected visual acuity using the ETDRS chart, slit-lamp biomicroscopy, fundoscopy, and spectral domain optical coherence tomography (SD-OCT) to measure central subfield thickness. The study concludes at Week 12, which is the end-of-study visit for all participants.

This research focuses on participants with narcolepsy type 1, narcolepsy type 2, and idiopathic hypersomnia. It is a long-term extension study following a previous trial, aiming to evaluate the long-term safety, tolerability, and effectiveness of the drug ORX750 in these conditions. The study is part of a Phase 2 clinical trial program specifically involving participants who completed the initial parent study. Participants will receive oral ORX750 during the long-term extension period. This open-label study continues treatment with ORX750, allowing researchers to observe its effects over an extended time without a placebo comparison. The study builds upon prior treatment to assess ongoing outcomes and safety. During the study, participants will be closely monitored for any treatment-emergent adverse events, serious adverse events, abnormal lab tests, changes in vital signs, abnormal ECG results, and any signs of suicidal thoughts or behavior up to day 70. The study requires participants to adhere to protocol requirements and will assess their continued safety and response to ORX750 throughout the treatment period.

Researchers are evaluating the effectiveness, safety, tolerability, and pharmacodynamics of multiple doses of APL-3007 combined with Syfovre/Pegcetacoplan (APL-2) in patients aged 60 years and older diagnosed with geographic atrophy secondary to age-related macular degeneration. This Phase 2, randomized, placebo-controlled, multicenter, masked study focuses on measuring changes in retinal pigment epithelium lesions using advanced artificial intelligence-based SD-OCT imaging. Participants will receive either the combination of APL-3007 with pegcetacoplan (APL-2) or a placebo. The study includes a treatment period with multiple doses administered, aiming to assess the impact on geographic atrophy lesions over a 12-month period. Syfovre injections at 6-8 week intervals prior to enrollment are part of the inclusion criteria. During the study, participants will undergo various eye imaging assessments such as OCT and FAF to monitor lesion size and progression. Researchers will evaluate changes in lesions at month 12 compared to baseline. Safety and tolerability will be closely monitored through laboratory tests, clinical evaluations, and vaccination status requirements. The study duration includes regular visits for treatment administration and monitoring over at least one year.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study to see if it can reduce the risk of major adverse cardiovascular events (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for a first ASCVD event. The study compares AZD0780 to a placebo and monitors participants from randomization until the primary analysis censoring date, followed by a final study closure visit. Participants will be randomly assigned to receive either oral AZD0780 or an oral placebo once daily. The treatment period lasts until the primary analysis censoring date, after which a study closure visit will occur. The study is event-driven and designed to assess the time to the first major cardiovascular event during treatment. During the study, participants will be closely monitored with various assessments to evaluate cardiovascular outcomes and safety over approximately 54 months. Researchers will track the time to first event of any component of MACE-PLUS and collect data to assess the effect of AZD0780 compared to placebo. The study includes regular visits and evaluations to ensure participant safety and adherence to treatment.

Researchers are evaluating the safety and effectiveness of Vagus Nerve Stimulation (VNS) Therapy as an additional treatment compared to no stimulation in people with treatment-resistant depression. This prospective, multi-center, randomized, controlled, blinded trial focuses on reducing depressive symptoms over 12 months using multiple depression rating scales. The study follows guidelines from the Centers for Medicare and Medicaid Services regarding evidence development for this treatment. Participants receive implantation of the VNS device, which delivers stimulation to the vagal nerve. After a minimum two-week period post-implantation, participants are randomly assigned to either active VNS treatment or no stimulation control, with outcomes observed for 12 months. Following this randomized phase, all participants enter an open-label extension where those in the control group receive active stimulation. Additional subjects may join this open-label study for up to five years to further assess long-term effects. Throughout the study, participants undergo regular assessments including the Montgomery Åsberg Depression Rating Scale (MADRS), WHO Disability Assessment Schedule, Health Outcome Scale, Clinical Global Impressions Scale, and Suicidality Tracking Scale. Researchers monitor response rates, remission times, duration of effects, and adverse events from implantation through 12 months. This comprehensive evaluation includes safety monitoring and functional outcome measures to understand the impact of VNS therapy on depression and related disabilities.

Researchers are evaluating corneal endothelial cells in people aged 50 and older who have neovascular age-related macular degeneration (nAMD). The study focuses on participants treated with the Port Delivery System (PDS) refilled every 24 weeks. This Phase IV, open-label trial aims to understand changes in corneal endothelial cell density over time in the eye receiving treatment compared to the fellow eye. The study involves delivering ranibizumab 100 mg/mL via the PDS implant. Supplemental treatment with intravitreal injections of ranibizumab (0.5 mg of a 10 mg/mL formulation) in the study eye may be given if needed. If participants stop the study treatment, they may receive intravitreal ranibizumab injections based on the investigator's judgment. Treatment and monitoring occur over at least 48 weeks. Participants will undergo detailed eye examinations including specular microscopy to measure corneal endothelial cell density at baseline and week 48. Historical visual acuity and imaging data will be reviewed. Researchers will monitor safety, disease activity, and treatment response through visual acuity assessments, optical coherence tomography, and other imaging techniques. The main outcome is the percent change in corneal endothelial cell density in the treated eye compared to the fellow eye after 48 weeks.

This research aims to evaluate the effectiveness and safety of two different dose schedules of pegozafermin compared to a placebo in adults with metabolic dysfunction-associated steatohepatitis (MASH) who have liver fibrosis at stage F2 or F3. This phase 3 study focuses on improving liver fibrosis and steatohepatitis in this patient group, which involves chronic liver disease associated with metabolic dysfunction. Participants will receive either pegozafermin or a placebo through subcutaneous injections. The study compares two doses of pegozafermin to assess their impact on liver fibrosis and steatohepatitis. The treatment period lasts up to 52 weeks, with outcomes measured at this time point. During the study, participants will be monitored for improvements in liver fibrosis and resolution of steatohepatitis without worsening fibrosis by week 52. Researchers will also track the time until any disease progression occurs, up to 5 years. Throughout the trial, safety and efficacy will be carefully assessed through clinical evaluations and laboratory tests to ensure participant well-being.
