Researchers are evaluating the safety and effects of a medicine called Ritlecitinib for adults with moderate to severe hidradenitis suppurativa HS, a condition that causes long-lasting painful red lumps on the skin. The study focuses on participants who have not responded well to or cannot tolerate antibiotics for HS. This Phase 2, randomized, double-blind, placebo-controlled study aims to understand how Ritlecitinib compares to placebo in treating this condition. Participants will be randomly assigned to take either Ritlecitinib or a matching placebo by mouth once daily at home. The study includes a loading dose of Ritlecitinib for the first 8 weeks, followed by a maintenance dose for the next 8 weeks, totaling 16 weeks of treatment. The placebo group will follow the same schedule with a pill that looks like the study medicine but contains no active drug. Throughout the study, participants will have about 10 clinic visits over approximately 24 weeks, including screening, Day 1, and follow-ups every 1, 2, or 4 weeks until Week 16. At these visits, health status will be reviewed through physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. Participants will also record daily medication intake and HS symptoms using a mobile eDiary. Researchers will measure skin response and safety outcomes to assess the effects of the study medicine compared to placebo.

Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation CIC. This study is a 26-week, multi-center, randomized, double-blind, placebo-controlled trial followed by a 4-week treatment-free safety follow-up period. It aims to compare three different doses of tenapanor with a placebo taken twice daily to assess their impact on constipation symptoms. The study includes a 2-week screening period to confirm eligibility, followed by a 26-week randomized treatment period where patients receive either 5 mg, 25 mg, or 50 mg of tenapanor twice daily, or a matching placebo. Patients record their constipation symptoms daily in an electronic diary. After the treatment period, there is a 4-week safety follow-up without treatment to monitor any adverse effects. Participants will have regular visits every 2 to 6 weeks for safety checks including medical assessments, vital signs, ECG, and lab tests. Their symptom diaries will be reviewed throughout the study. The main outcome measured is the durable complete spontaneous bowel movements response at 12 weeks. Secondary outcomes include changes in bowel movement frequency, stool consistency, and straining. The total study duration is approximately 32 weeks including all phases.

Researchers are evaluating MK-2214, a study treatment designed to slow brain changes in people with early Alzheimers disease AD. AD is a form of dementia that causes memory loss, communication difficulties, and challenges in decision-making, affecting daily tasks. This phase 2 trial aims to determine if MK-2214 slows the spread of tau protein in the brain compared to a placebo, as well as to assess the safety and tolerability of MK-2214. Participants will be randomly assigned to receive either MK-2214 or a placebo through intravenous IV infusion every 4 weeks during the study. The study uses a parallel design with quadruple masking to compare the effects of the study drug versus placebo over a period of up to approximately 23 months. Both groups receive infusions on the same schedule to maintain the studys integrity. During the study, participants will undergo brain scans including positron emission tomography PET to measure tau protein levels and other assessments such as cognitive and daily living function tests. Researchers will monitor adverse events and treatment discontinuations throughout the study, which lasts up to about 26 months. These assessments help determine the impact of MK-2214 on disease progression and safety in individuals with early AD.

Researchers are investigating new treatments for neovascular age-related macular degeneration NVAMD, a condition that affects vision. This study aims to learn if a medicine called tiespectus also known as MK-8748 or EYE201 can treat NVAMD as well as the standard treatment called aflibercept. The trial is a pivotal Phase 23 study that compares these treatments in people newly diagnosed with NVAMD. Participants are randomly assigned to one of three groups one group receives a low dose of tiespectus, another receives a high dose of tiespectus, and the third group receives aflibercept. Those in the tiespectus groups get three initial injections every 4 weeks, then continue injections every 8 weeks until week 48, followed by treatments at intervals based on their individual response up to week 92. The aflibercept group receives three initial injections followed by injections every 8 weeks until week 92. During the study, participants are regularly assessed for changes in their best-corrected visual acuity using ETDRS letters from baseline to one year. Other evaluations include eye imaging to measure retinal thickness and monitoring for any adverse events up to approximately 96 weeks. The study lasts over one year with ongoing visits to track treatment response and safety.

This research investigates intravitreal EYE103 in adults with neovascular age-related macular degeneration NVAMD or macular edema caused by branch retinal vein occlusion BRVO. The trial is randomized and dose-masked, including four different patient groups to study different doses and combinations of EYE103, aiming to assess its effects in these eye conditions. Participants are divided into four cohorts treatment-naive NVAMD, incomplete responders IR with NVAMD as monotherapy, IR NVAMD combined with aflibercept, and treatment-naive BRVO. Each cohort randomly receives either a low or high dose of EYE103 via intravitreal injection. All receive three injections spaced 4 weeks apart the IR NVAMD combination group also receives aflibercept on Day 1. Assessments occur at each injection visit and some groups return 2 weeks post-injection for extra evaluations. During the 12-week study, participants undergo safety and efficacy assessments including vision tests using ETDRS charts, slit-lamp exams, fundoscopy, and imaging with spectral domain optical coherence tomography SD-OCT to measure retinal thickness. The studys main measure is the change in best-corrected visual acuity at Week 12. The trial also monitors retinal thickness and vision changes throughout. The Week 12 visit marks the studys end for all participants.

Researchers are conducting a long-term extension study to evaluate the safety, tolerability, and effectiveness of ORX750 in adults aged 18 to 65 years who have narcolepsy type 1, narcolepsy type 2, or idiopathic hypersomnia. This study follows participants who completed a previous ORX750 clinical trial and focuses on providing ongoing information about the treatment over an extended period. Participants will receive oral ORX750 in an open-label format, grouped by their specific diagnosis narcolepsy type 1, narcolepsy type 2, or idiopathic hypersomnia. The study does not involve randomization or blinding, allowing all participants to know they are receiving the study drug. The treatment and monitoring periods include assessments up to about 70 days for safety and roughly 63 days for measures of drug concentration and wakefulness. During the study, participants will undergo frequent evaluations including monitoring for adverse events, laboratory tests, vital signs, ECGs, and assessments for suicidal thoughts or behaviors. They will also complete tests measuring wakefulness and sleepiness levels. This ongoing observation aims to ensure the treatments safety and to understand its effects over time, with participant involvement lasting through the entire study period.

Researchers are investigating the effects of APL-3007 combined with SyfovrePegcetacoplan APL-2 in patients with geographic atrophy caused by age-related macular degeneration AMD. This Phase 2 randomized, placebo-controlled study aims to assess the efficacy, safety, tolerability, and pharmacodynamics of these treatments in this eye condition. The study involves multiple centers and uses a masked design to ensure unbiased results. Participants will be assigned to one of three groups two receiving different doses or frequencies of APL-3007 in combination with pegcetacoplan APL-2, and one receiving a placebo along with pegcetacoplan APL-2. The study will evaluate the treatments given as multidose regimens. The treatments focus on complement C3 inhibition to potentially impact disease progression. Throughout the study, participants will undergo assessments including artificial intelligence-based imaging to measure retinal pigment epithelium lesion area and photoreceptor degeneration, safety evaluations through adverse event reporting and visual acuity tests, and blood tests to assess serum markers. These evaluations occur over 12 months to monitor changes from baseline. Participants involvement includes regular visits for these assessments, with the study tracking treatment effects and safety over the duration.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study. This trial focuses on patients with established atherosclerotic cardiovascular disease ASCVD or those at high risk for a first ASCVD event. The study aims to assess how AZD0780 compares to placebo in reducing the risk of major adverse cardiovascular events, also known as MACE-PLUS, over the course of the trial. Participants are randomly assigned to receive either oral AZD0780 once daily or a matching placebo once daily. The study continues until a primary analysis censoring date, which may be up to approximately 54 months from randomization. After this, a study closure visit will be conducted as the final visit for each participant. During the study, participants will be regularly monitored for cardiovascular events including heart attacks, strokes, urgent coronary revascularizations, and other related outcomes. Researchers will track the time to first occurrence of these events as the primary outcome. Safety and other secondary outcomes like all-cause mortality will also be assessed. The total participation time can last up to about 54 months, with ongoing evaluations throughout this period.

Researchers are evaluating the safety and effectiveness of the Vagus Nerve Stimulation VNS Therapy System as an additional treatment for people with treatment-resistant depression. This prospective, multi-center, randomized, controlled, and blinded trial compares active VNS therapy to a no stimulation control group in reducing depressive symptoms over 12 months. The study follows guidelines aligned with Medicare and Medicaid coverage decisions for VNS in this condition. Participants receive an implant of the VNS device and are randomized at least two weeks after implantation to either have the device activated or remain without stimulation for the first 12 months. After this initial period, those in the control group can begin stimulation. Following the 12-month randomized phase, all participants enter an open-label, longitudinal study lasting about five years, including new enrollees after the initial trial phase. During the study, participants are monitored through various depression rating scales, including the Montgomery sberg Depression Rating Scale MADRS, to assess response and remission rates up to 12 months. Safety is tracked by recording adverse events from implantation through the first year. Additional assessments include disability and health outcome scales, as well as suicidality tracking. The study aims to gather long-term data on treatment effects and participant well-being.

The trial investigates the corneal endothelial cells in adults aged 50 and older with neovascular age-related macular degeneration nAMD who are treated with the Port Delivery System PDS implant delivering ranibizumab. This Phase IV, open-label study aims to monitor changes in corneal endothelial cell density over time, comparing the treated eye with the fellow eye to evaluate the effects of this device-based treatment approach. Participants will have a PDS implant surgically inserted in the study eye, initially filled with ranibizumab before implantation. Following this, the implant will be refilled every 24 weeks. Supplemental intravitreal ranibizumab injections may be given if the participant stops study treatment, based on investigator discretion. The study monitors participants for at least 48 weeks, focusing on corneal cell changes and ocular safety events. During the study, participants undergo assessments including specular microscopy to measure corneal endothelial cell density and morphology at baseline and at weeks 24 and 48. Researchers will track ocular adverse events, device-related effects, and serious safety concerns throughout the approximately one-year follow-up. The study collects visual acuity data, imaging results, and historical treatment records to support evaluation. Participants remain under close observation to assess treatment impact and safety.
