Researchers are evaluating the long-term safety and tolerability of JNJ-81201887, given as an intravitreal injection a shot into the eye, in participants with Geographic Atrophy GA secondary to Age-related Macular Degeneration AMD. This study is a long-term extension of parent clinical trials where participants had previously received either low or high doses of JNJ-81201887 or a sham procedure. The goal is to monitor participants over an extended period to understand any lasting treatment effects or side effects. Participants entering this long-term extension study will not receive additional doses of the study drug or any new intervention as part of this trial. They previously participated in parent studies where they were treated with either low dose or high dose JNJ-81201887 or sham procedure. Some participants who were in the sham group of the parent study may receive open-label treatment outside this study before entering this extension. This study focuses solely on follow-up without new treatment administration. Throughout the study, participants will undergo regular assessments to monitor ocular and systemic safety. These include tracking treatment-emergent adverse events, clinical laboratory tests, retinal imaging, and eye examinations over up to five years. This extended monitoring aims to evaluate the long-term safety profile of the previous treatments. Participants will be followed with periodic visits and evaluations, with the total study duration extending until 2030.

Researchers are evaluating whether retatrutide and tirzepatide can prevent major adverse liver outcomes in adults with metabolic dysfunction-associated steatotic liver disease MASLD who are at high risk based on non-invasive tests. This Phase 3 randomized controlled trial aims to assess these treatments compared to placebo in about 4,500 adults over approximately 224 weeks. The study is sponsored by Eli Lilly and Company and focuses on liver disease progression and related health measures. Participants will be randomly assigned to receive retatrutide, tirzepatide, or placebo, all administered by subcutaneous injection. The trial includes two placebo groups corresponding to each experimental drug. After completing the main study, eligible participants may join a 2-year extension where all will receive either retatrutide or tirzepatide regardless of their initial assignment. During the study, participants may attend around 25 to 30 clinic visits for health monitoring, study procedures, and assessments of liver function and disease status. Researchers will measure the time to major adverse liver outcomes, changes in liver fibrosis scores, liver stiffness, liver fat content, liver enzyme levels, body weight, and cardiovascular events. Monitoring will continue from baseline through study completion, with detailed evaluations at multiple timepoints including week 104.

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 oral icotrokinra as a treatment for adults and adolescents with moderately to severely active ulcerative colitis, a chronic inflammatory disease of the large intestine causing ulcers in the colon lining. The study aims to assess how well icotrokinra works, along with its safety and tolerability in this population. This is a Phase 3, randomized, double-blind, placebo-controlled trial with a parallel group design including both adults and adolescents. Adult participants will be randomly assigned to receive either icotrokinra or placebo daily by mouth during a 12-week induction phase. At Week 12, those showing clinical response will enter a maintenance phase where they will continue icotrokinra or placebo daily for 40 weeks. Adults who do not respond will also enter the maintenance phase and receive icotrokinra. Adolescents will receive open-label icotrokinra during induction and then continue on icotrokinra during maintenance regardless of response. After completing the 40-week maintenance phase, eligible participants may join a long-term extension study. Participants will be monitored regularly through clinical assessments at specified time points including Week 12 for induction and Week 40 for maintenance. Outcomes measured include rates of clinical remission, symptom improvement, endoscopic and histologic healing, and quality of life scores. Safety will be evaluated by tracking adverse and serious adverse events throughout the study. The total study duration may extend up to approximately 6 years, ending in 2032, allowing long-term evaluation of icotrokinra in ulcerative colitis management.

Researchers are evaluating the safety, tolerability, and effectiveness of a one-time intravitreal injection of SAR446597 in people with Geographic Atrophy GA caused by Age-related Macular Degeneration AMD. This sequential Phase 12 study includes two parts and will take place at multiple centers. The study aims to learn how well this treatment works and how safe it is for participants with this eye condition. Participants will receive a single intravitreal injection of SAR446597, with different dose levels tested across successive groups in Part I. In Part II, participants may receive SAR446597 at one of two dose levels or a sham injection as a control. The core study phase lasts about 2 years per participant, followed by an additional 3-year Extended Follow-Up phase to monitor long-term effects. Throughout the study, participants will undergo regular assessments including eye exams to measure changes in the size of GA lesions and visual acuity using standardized charts. Safety will be monitored closely by tracking any treatment-related adverse events. The total participation time spans approximately 5 years, allowing researchers to evaluate both short- and long-term outcomes of SAR446597 treatment.

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.

Researchers are evaluating the safety and effectiveness of 48 weeks of daily oral treatment with ALG-000184 compared to tenofovir disproxil fumarate TDF in adults with chronic hepatitis B virus HBV infection.
