Researchers are conducting an open-label, multi-center, non-randomized pivotal Phase 3 study to evaluate the effectiveness and safety of PET imaging using [18F]PI-2620 for detecting tau protein buildup in people with Alzheimer's disease and control subjects. The study compares PET imaging results during life with brain tissue analysis obtained after death through autopsy, aiming to improve diagnosis of tau-related brain changes. Participants will receive an intravenous injection of the radioligand [18F]PI-2620 at a dose of 185 MBq 20%. The PET imaging will be performed to visualize tau deposits in the brain. This study focuses on assessing the diagnostic accuracy of this imaging method by comparing it to post-mortem histopathology findings. Throughout the study, participants will undergo PET scans and assessments to determine the presence and extent of tau pathology. The primary outcome measure is the ability of visual assessment of [18F]PI-2620 PET images to correctly distinguish tau neurofibrillary pathology associated with Alzheimer's disease, confirmed at autopsy within about one year. Safety and tolerability during imaging procedures will also be monitored, with a total participation period depending on the timing of brain autopsy after death.

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.

Researchers are investigating whether buntanetap/Posiphen can help treat early Alzheimer's disease in adults aged 55 to 85 years. This Phase 3 study aims to find out if buntanetap/Posiphen improves thinking abilities and daily functioning compared to a placebo. It also evaluates the safety of buntanetap/Posiphen by monitoring any medical issues that participants may experience during the trial. Participants will take either a 30 mg capsule of buntanetap/Posiphen or a placebo capsule by mouth once daily for 18 months. The study includes regular clinic visits at screening, enrollment, and months 1, 3, 6, 9, 12, 15, and 18. During some visits, participants will have brain MRI scans. The study uses a double-blind design, meaning neither participants nor researchers know who receives the active drug or placebo. Throughout the study, participants will complete tests and questionnaires to measure cognitive function and daily living activities, including the ADAS-Cog13 and ADCS-iADL scales. Phone calls before and after visits help track progress and adherence. Safety is closely monitored with ongoing assessments from screening through the 18-month treatment period.

Researchers are evaluating the effects of two different methods of giving pegloticase, a drug for uncontrolled gout, combined with methotrexate (MTX). This Phase 3 trial compares pegloticase given as an 18 mg injection under the skin every two weeks with pegloticase given as an 8 mg intravenous (IV) infusion every two weeks, both alongside weekly oral MTX. The main goal is to see which method better maintains normalized serum uric acid levels below 6 mg/dL for at least 80% of the time during the sixth month of treatment. Participants will be randomly assigned to receive pegloticase either by subcutaneous injection or intravenous infusion every two weeks, along with weekly oral doses of methotrexate. Both groups will be treated over several months while closely monitored. The study is double-blind, meaning neither participants nor researchers know which treatment is being given to maintain unbiased results. During the trial, participants will undergo regular assessments to monitor their serum uric acid levels and overall response to treatment, especially focusing on weeks 20 through 24 (Month 6). Safety and efficacy will be tracked throughout the study, including how well participants tolerate the treatments and any side effects. The study's main measure is the proportion of participants who achieve a sustained uric acid response during Month 6.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.

Researchers are evaluating the safety and effectiveness of rilvegostomig compared to pembrolizumab, both combined with platinum-based doublet chemotherapy, as initial treatments for patients with metastatic non-squamous non-small cell lung cancer (mNSCLC) whose tumors express PD-L1. This Phase III, randomized, double-blind, global study focuses on patients whose tumors meet the PD-L1 expression threshold of 1% or higher and do not have certain genetic mutations or rearrangements that would require other targeted therapies. Participants receive either rilvegostomig or pembrolizumab intravenously on the first day of each 21-day treatment cycle. Both groups also receive platinum-based chemotherapy drugs such as carboplatin or cisplatin, administered intravenously up to four cycles, along with pemetrexed given intravenously on Day 1 of each cycle. The study monitors these treatments as first-line therapy for metastatic non-squamous NSCLC. During the study, participants undergo regular assessments including imaging scans to measure tumor size and response, as well as evaluations of organ and bone marrow function. Researchers track overall survival and progression-free survival for up to approximately five years. Safety is closely monitored throughout, and patients are followed long-term to assess outcomes related to treatment effectiveness and tolerability.

This is a Phase III, two-arm, randomized, double-blind, global, multicenter study assessing the efficacy and safety of rilvegostomig compared to pembrolizumab, both in combination with platinum-based doublet chemotherapy, as a first-line (1L) treatment for patients with squamous metastatic non-small cell lung cancer (mNSCLC) whose tumors express PD-L1 (tumor cells (TC) ≥ 1%).

Researchers are studying the effects of NEU-411 in men and women aged 40 to 80 years who have early Parkinson's Disease (PD) with increased activity in the LRRK2 pathway, identified through a genetic test. This Phase 2 trial aims to evaluate how well NEU-411 works and its safety in this specific group compared to a placebo. The study involves participants with clinically established or probable PD and focuses on those with LRRK2-driven PD. Participants will be randomly assigned to receive either NEU-411, a brain-penetrant oral drug that inhibits LRRK2 activity, or a matching placebo once daily for 52 weeks. After completing this treatment phase, participants will have a safety follow-up visit within two weeks. Those eligible may join an open-label extension to receive NEU-411 for an additional 26 weeks. During the study, researchers will monitor changes in a digital biomarker score using a Parkinson's Disease app from enrollment through 52 weeks, along with recording any treatment-emergent or serious adverse events until the study ends at 54 weeks. Assessments include genetic testing, clinical evaluations of PD status, safety monitoring, and tracking of side effects to understand the drug's effects and tolerability over time.

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 conducting a Phase 3 study to evaluate the safety and effectiveness of an intravitreal injection called KSI-101 in adults with macular edema caused by inflammation, known as MESI. This condition involves swelling in the central part of the retina and can affect vision. The study aims to compare KSI-101 to sham injections to understand its impact on improving vision. Participants will receive either KSI-101 or sham injections directly into the eye. The treatment is given through intravitreal injections, which deliver medication inside the eye. The study is randomized, double-masked, and sham-controlled, meaning neither participants nor doctors know who receives the active drug or sham injections. This design helps provide clear and unbiased results. Throughout the study, participants will have their vision assessed, including measuring changes in best-corrected visual acuity (BCVA) at 24 weeks. Researchers will monitor the thickness of the central retina area and check for safety and side effects. Participants will be followed regularly to track vision changes and eye health during the study period.
