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 studying the effectiveness and safety of a combination inhaler containing fluticasone propionate and albuterol sulfate delivered through a multidose dry powder inhaler with an electronic module (Fp/ABS eMDPI). This Phase 3 trial focuses on people aged 12 years and older who have asthma. The study also looks at the safety and tolerability of this inhaler when used four times daily over four weeks, as well as the pharmacokinetics of the combination and its individual components after a single dose. Participants will be randomly assigned to receive either the Fp/ABS combination inhaler, fluticasone propionate alone, albuterol sulfate alone, or a placebo inhaler. All treatments are given as inhalation powders. The main treatment period lasts four weeks, during which the inhalers are taken four times a day. The total study duration for each participant is about 10 weeks, not counting an optional prescreening visit. Throughout the study, researchers will measure lung function changes, specifically forced expiratory volume in one second (FEV1), from baseline to week 4. Participants will undergo assessments including lung function tests and safety evaluations. The study monitors how the inhaler affects breathing over time and checks for any side effects or tolerability issues during the treatment period.

Researchers are evaluating the effect of a triple therapy inhaler called BGF MDI containing budesonide, glycopyrronium, and formoterol fumarate compared with a dual therapy inhaler called GFF MDI containing glycopyrronium and formoterol fumarate in people with Chronic Obstructive Pulmonary Disease (COPD) who have a higher risk of heart and lung problems. This Phase III randomized, double-blind, parallel group study takes place at multiple centers and focuses on cardiopulmonary outcomes in these patients. Participants receive either the BGF MDI 320/14.4/9.6 micrograms twice daily or the GFF MDI 14.4/9.6 micrograms twice daily. The treatments are inhaled using metered dose inhalers. The study compares these two therapies over time to see how they affect the time until the first severe heart or lung event occurs. The study design ensures that neither participants nor researchers know which treatment is given to reduce bias. During the study, participants will have regular visits to the study site or virtual visits to complete assessments. Researchers will monitor lung function, symptoms, and blood tests, including blood eosinophil counts and COPD assessment test scores. The main outcome measured is the time to the first severe cardiac or COPD event, with follow-up lasting up to three years. Safety and adherence to treatment will also be closely observed throughout the study period.

This research aims to assess the effectiveness and safety of lebrikizumab in adults diagnosed with perennial allergic rhinitis, a condition characterized by year-round nasal allergy symptoms. The study is a Phase 3 trial involving adult participants who have confirmed allergic reactions to indoor allergens. Researchers are investigating how lebrikizumab compares with placebo, alongside standard intranasal corticosteroid therapy, to better understand treatment options for this condition. Participants will receive either the investigational drug lebrikizumab (LY3650150) administered by subcutaneous injection, a placebo injection, or standard intranasal corticosteroid spray. The study is randomized, double-blind, and placebo-controlled, ensuring that neither participants nor researchers know who receives which treatment during the trial. Treatment and observation periods will span up to 29.5 months. During the study, participants will be monitored for changes in their nasal symptoms, specifically measuring the total nasal symptom score from the start of the study to week 16. Researchers will conduct various assessments including clinical evaluations and allergy testing to track symptom changes and treatment effects. Safety will be closely observed throughout the study duration, and participants may be followed for nearly two and a half years in total.

Researchers are evaluating the effects of a combination treatment of Fluticasone Furoate (FF), Umeclidinium (UMEC), and Vilanterol (VI) on lung function in adolescents aged 12 to 17 years with asthma that is not well controlled by current treatments. This Phase 3 study compares this three-drug combination with a two-drug combination of FF and VI over a 24-week period to assess their impact on breathing ability and safety. Participants will receive either the FF/UMEC/VI combination or the FF/VI combination, both delivered using the ELLIPTA inhaler device. The treatment will be administered consistently over 24 weeks, with the study designed as a randomized, double-blind, parallel-group trial to fairly compare the two therapies. The goal is to observe differences in lung function and other health effects during this treatment period. During the study, participants will undergo evaluations including lung function tests measuring forced expiratory volume in 1 second (FEV1) at the start and after 24 weeks of treatment. Researchers will monitor safety, tolerability, and how well participants respond to the therapies. The total participation time spans these 24 weeks of treatment, with assessments to track changes and effects throughout the study.

Researchers are evaluating the effectiveness of remibrutinib compared to dupilumab in adults with moderate to severe chronic spontaneous urticaria (CSU) that is not adequately controlled by second generation H1-antihistamines (sgH1-AHs). This Phase 3b, multi-center, randomized, double-blind, double-dummy study is conducted in the US and focuses on early treatment effects at 4 weeks and earlier. The study includes a screening period of up to 4 weeks, followed by a 12-week core treatment period where about 400 participants are randomly assigned to receive either remibrutinib (25 mg twice daily by mouth) with a placebo injection or dupilumab (a 600 mg loading dose followed by 300 mg every 2 weeks by injection) with a placebo tablet. All participants continue their stable dose of sgH1-AH during this period, with the option to add rescue doses if needed, not exceeding four times the standard dose per day. After the core period, participants may join an optional open-label extension to receive remibrutinib for an additional 12 weeks if the drug is not commercially available. Participants will complete daily diaries and regular assessments to track urticaria symptoms and treatment effects. Researchers will measure changes in the Weekly Urticaria Activity Score (UAS7) from the start to Week 4. Safety follow-up will occur for 12 weeks after treatment ends, with phone calls and site visits as needed, continuing longer if participants join the extension. The total study duration includes screening, treatment, optional extension, and safety follow-up phases.

Researchers are investigating the potential benefits of GB-0895 as an additional treatment for adolescents and adults with severe asthma that remains uncontrolled despite using inhaled corticosteroids and other usual asthma treatments. This global, multicenter Phase 3 trial compares the effects of GB-0895 to a placebo in patients aged 12 to 80 years with severe uncontrolled asthma. The study also includes an optional open-label extension phase to further assess long-term effects and safety. Participants are randomly assigned to receive either GB-0895 or a placebo through subcutaneous injections every 6 months over a 52-week treatment period. Before treatment, there is a screening and run-in phase lasting about 6 weeks. After the 52 weeks of treatment, participants enter a follow-up period lasting up to 38 weeks or may choose to join the optional open-label extension lasting up to 90 weeks, during which they continue receiving GB-0895 at specified intervals. Throughout the study, participants attend visits every 1 to 2 months after the first month to monitor their health and asthma control. Researchers evaluate the annualized asthma exacerbation rate as the main outcome. Safety assessments include physical exams, vital signs, lab tests, and careful monitoring for adverse effects. The study aims to enroll about 786 participants globally to thoroughly assess the safety and effectiveness of GB-0895 as an add-on therapy for severe uncontrolled asthma.

Researchers are evaluating the safety and effectiveness of tezepelumab in adults aged 40 to 80 years with moderate to very severe chronic obstructive pulmonary disease (COPD). These participants must have a history of COPD for at least one year and have experienced multiple COPD exacerbations despite using inhaled maintenance therapy. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on those who have had at least two moderate or one severe exacerbation in the prior year while on inhaled triple or dual therapy. Participants will receive monthly subcutaneous injections of either one of two doses of tezepelumab or a placebo. Treatment will last for a minimum of 52 weeks and up to 76 weeks. After the treatment period, there will be a 12-week off-treatment safety follow-up to monitor any lasting effects or safety concerns. During the study, researchers will assess the participants' lung function and monitor the annual rate of moderate or severe COPD exacerbations. Participants will undergo screening to confirm eligibility based on lung function tests, eosinophil counts, and symptom scores. Safety will be closely monitored throughout the treatment and follow-up periods to evaluate adverse effects and overall participant health.

This research aims to evaluate the effectiveness and safety of a fixed-dose combination of fluticasone propionate (Fp) and albuterol sulfate (ABS) delivered via an integrated electronic module multidose dry powder inhaler (eMDPI) compared to ABS alone in reducing severe clinical asthma exacerbations in patients with asthma. The study also assesses the efficacy of a low dose of Fp/ABS versus ABS and examines the impact on systemic corticosteroid exposure. This is a phase 3 randomized, double-blind, active-controlled trial involving patients diagnosed with asthma for at least one year. Participants will receive either a high dose or low dose of Fp/ABS or ABS alone through oral inhalation powder during a double-blind treatment period lasting a minimum of 24 weeks. The study includes a 2-week screening phase, a 2 to 4-week run-in period, and the treatment phase. Because this is an event-driven study, the total duration for individual participants may extend up to approximately 42 months depending on enrollment timing and study completion. During the study, participants will be closely monitored for time to first severe clinical asthma exacerbation while using the inhaler device. Safety and tolerability will be evaluated throughout the study. Researchers will also track systemic corticosteroid use and overall asthma control. The minimum participation time is 28 weeks, including screening and run-in, with extended monitoring possible based on study events and criteria.

Researchers are evaluating the effects of two inhalers, budesonide/albuterol metered-dose inhaler (BDA MDI) and albuterol sulfate metered-dose inhaler (AS MDI), both taken as needed, on reducing severe asthma attacks in adolescents aged 12 to under 18 years who have a clinical diagnosis of asthma and have experienced at least one severe asthma exacerbation in the past year. This is a Phase IIIb randomized, double-blind, multicenter study lasting 52 weeks with a safety follow-up period after treatment. Participants will be randomly assigned to receive either BDA MDI 160/180 micrograms (two puffs of 80/90 micrograms) or AS MDI 180 micrograms (two puffs of 90 micrograms) as needed, alongside their usual asthma maintenance therapy, for 52 weeks. The study includes a 7 to 28-day screening period before treatment and a safety follow-up visit 7 to 14 days after the end of treatment. Additionally, a pharmacokinetic sub-study involves a single dose of open-label BDA MDI administered after the safety follow-up. During the study, participants will be monitored for the annual rate of severe asthma exacerbations from randomization to week 52. Assessments include evaluating inhaler technique, peak expiratory flow measurements, and adherence to contraception methods for participants of childbearing potential. Safety will be monitored throughout the treatment and follow-up periods. The total study duration includes screening, 52 weeks of treatment, and safety follow-up.
