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 new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are investigating treatments for women with recurrent endometrial cancer that expresses different levels of the HER2 protein. The study has two groups based on the tumor's HER2 score: Cohort 1 includes patients with HER2 IHC 1+ or 2+ who have previously received immune checkpoint inhibitors and platinum-based chemotherapy, while Cohort 2 includes patients with HER2 IHC 3+. The purpose is to compare the effectiveness and safety of the investigational drug BNT323 (also called DB-1303) against chemotherapy in Cohort 1 and to evaluate BNT323 alone in Cohort 2. The study also looks at how the drug affects the immune system, the body's handling of the drug, quality of life, and potential side effects. Participants in Cohort 1 are randomly assigned to receive either BNT323 via intravenous infusion or a chemotherapy drug chosen by the investigator (doxorubicin, paclitaxel, or docetaxel if paclitaxel is unsuitable). Treatment continues until the cancer progresses, unacceptable side effects occur, or the participant withdraws consent. Those in Cohort 2 receive BNT323 alone until disease progression or other discontinuation criteria are met. The study includes a screening period, a treatment period expected to last about six months, followed by safety monitoring, efficacy follow-up, and long-term survival follow-up lasting up to approximately 53 months. During the study, participants undergo regular assessments including imaging scans to measure tumor response by RECIST criteria, safety monitoring for adverse effects, and evaluations of quality of life. Researchers also study the pharmacokinetics of BNT323 and the immune response. The main outcomes measured are progression-free survival in Cohort 1 and objective response rate in Cohort 2. Safety follow-up ensures ongoing monitoring after treatment to evaluate longer-term effects and participant wellbeing.

Researchers are evaluating the effectiveness and safety of Xeomin injections in preventing chronic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections given into muscles of the head and neck. Participants have chronic migraine diagnosed for at least 12 months and meet specific headache and migraine day criteria. The study aims to measure changes in monthly migraine days over time with Xeomin treatment. Participants will receive four treatments spaced about 12 weeks apart over a total study duration of 52 to 55 weeks. The treatments involve injections of either Xeomin or placebo solution prepared with sodium chloride. Visits occur approximately every 4 weeks, totaling 14 visits: the first, last, and four treatment visits are on-site, while the other eight visits are remote via phone or video call. During the study, participants will keep headache diaries to track migraine and headache days. Researchers will focus on the change in monthly migraine days from baseline to six months after the first injection. Safety and effectiveness are monitored throughout, with frequent assessments during both on-site and remote visits to ensure accurate tracking of migraine symptoms and any side effects.

Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing episodic migraine. This phase 3 clinical trial focuses on adults who experience episodic migraine, aiming to measure changes in the number of migraine days per month. Participants must have a diagnosis of episodic migraine for at least 12 months and meet specific headache frequency criteria. Participants will receive four treatments of either Xeomin or placebo injections into muscles of the head and neck, with treatments spaced about 12 weeks apart. The entire trial lasts approximately 52 to 55 weeks, beginning with a screening period of 4 to 5 weeks. There are about 14 visits in total, with the first, last, and four treatment visits conducted on-site, while the other visits are held remotely via phone or video. Throughout the study, participants will track their migraine days using a headache diary, and researchers will assess changes in monthly migraine frequency from baseline to six months after the first injection. Regular monitoring includes both in-person and remote assessments. The primary outcome focuses on the change in monthly migraine days between baseline and month six after treatment initiation.

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 effectiveness and safety of ACR-368 alone or combined with ultra-low dose gemcitabine (ULDG) sensitization in people with endometrial cancer. This is an open-label Phase 2 study involving participants with high-grade endometrial adenocarcinoma. Participants are grouped based on a test called OncoSignature, which predicts sensitivity to ACR-368, or by tumor subtype without requiring the test. Participants in Arm 1 and Arm 4 receive ACR-368 as a single treatment, while those in Arms 2 and 3 receive ACR-368 combined with ULDG sensitization. Arms 1 and 2 are for participants selected by OncoSignature status, while Arms 3 and 4 include participants with serous carcinoma regardless of OncoSignature results. Treatment continues until the disease progresses, unacceptable side effects occur, or the participant withdraws. Participants will have tumor response assessed every 8 weeks from the start of treatment through two years or until death. To join, participants must have measurable metastatic cancer that progressed after prior therapies, provide tumor tissue samples, and meet health and organ function requirements. Safety and response will be closely monitored throughout the study.

Researchers are evaluating the safety and effectiveness of two combined treatments, KarXT and KarX-EC, for adults aged 55 to 90 who experience agitation related to Alzheimer's Disease. This Phase 3, randomized, double-blind, placebo-controlled study aims to better understand how these treatments may help reduce agitation symptoms in this population while monitoring safety. Participants will receive either the active drugs Xanomeline/Trospium Chloride Capsule and Xanomeline Enteric Capsule or a placebo, taken at specified doses on designated days. The study is carefully designed to compare these treatments against placebo to evaluate their impact on agitation symptoms associated with Alzheimer's Disease. During the study, participants will be assessed using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association (CMAI-IPA) total score to measure changes from baseline at Week 14. Caregivers will be involved to help monitor compliance and report participant status throughout the study. Safety and efficacy will be closely monitored during this 14-week period to gather detailed information about treatment outcomes.

This research aims to understand the safety, effectiveness, and overall treatment experience of participants prescribed BRIUMVI4 (ublituximab-xiiy) in a real-world setting. The study focuses on people living with relapsing multiple sclerosis (RMS), a form of multiple sclerosis characterized by episodes of new or increasing neurological symptoms. It is designed to gather detailed insights from actual use outside of controlled clinical trials. Participants in this study are those who have been prescribed BRIUMVI4 but have not yet received their first infusion at the start of the study. There is no intervention assigned by the study itself; instead, it observes the outcomes and experiences of patients treated with BRIUMVI4 as part of their routine care over time. Throughout the study, researchers will track the annualized relapse rate (ARR) up to week 96 to measure disease activity. Participants' safety, treatment adherence, and experiences will be evaluated through regular monitoring, including any adverse events. The total duration of participation covers up to 96 weeks, allowing for a comprehensive understanding of long-term treatment effects and patient-reported outcomes.

Researchers are evaluating how well elacestrant works compared to standard endocrine therapy in adults with node-positive, Estrogen Receptor-positive (ER+), Human Epidermal Growth Factor-2 negative (HER2-) early breast cancer who are at high risk of the cancer returning. This is a Phase 3 global, multicenter, randomized, open-label study focusing on participants who have had early invasive breast cancer removed and meet specific receptor and risk criteria. The study aims to understand which treatment better prevents invasive breast cancer over up to five years. Participants will receive either elacestrant or one of several standard endocrine therapies, including anastrozole, letrozole, exemestane, or tamoxifen, all given as oral tablets. Treatments will be administered according to the study plan, with careful monitoring throughout the trial. The study includes adults who have already received between 24 and 60 months of prior endocrine therapy, with or without certain inhibitors, and who have completed or stopped these treatments as required. During the study, participants will be monitored for invasive breast cancer-free survival for up to five years. Researchers will perform regular assessments to track treatment effects, side effects, and cancer recurrence. The study also includes safety monitoring and may involve additional tests or evaluations as needed to ensure participant well-being throughout the trial.
