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 treatment's safety and to understand its effects over time, with participant involvement lasting through the entire study period.

Researchers are evaluating the LIAISON NES FLU A/B, RSV & COVID-19 assay used on the LIAISON NES instrument for detecting and distinguishing influenza A, influenza B, RSV, and SARS-CoV-2 viruses in patients showing symptoms of respiratory tract infections. This test is designed to help in the differential diagnosis of these infections in a professional laboratory setting, but negative results alone should not guide patient management as they do not rule out infection. The study is interventional and involves multiple sites. The trial involves collecting clinical specimens, mainly nasal swabs, from symptomatic patients. These specimens are collected prospectively by healthcare professionals, with up to 40% possibly self-collected under supervision. Nasopharyngeal swabs may also be collected by professionals, especially in children 13 years or younger. The assay uses real-time polymerase chain reaction (RT-PCR) to detect viral RNA directly from dry nasal swabs without the need for nucleic acid extraction. Participants will provide nasal or nasopharyngeal swabs preserved in specific transport media, which are tested on the LIAISON NES instrument within one to two hours of collection. The study measures the diagnostic accuracy and clinical performance of the assay. Specimens are carefully stored and handled to maintain quality. The trial monitors conditions including influenza A, influenza B, RSV, and COVID-19 infections and is expected to complete by May 2025.

Researchers are evaluating the effect of AZD0780, an oral PCSK9 inhibitor, compared with a placebo in reducing the risk of major adverse cardiovascular events plus (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or at high risk for a first ASCVD event. This phase 3, randomized, placebo-controlled, and double-blind study aims to assess the time to first MACE-PLUS event over up to approximately 54 months from randomization until the primary analysis censoring date. Participants will be randomly assigned to receive either oral AZD0780 once daily or an oral placebo once daily. The study includes a parallel-group design with two arms: the experimental AZD0780 group and the placebo comparator group. After the primary analysis censoring date, a study closure visit will be scheduled as the final visit for each participant. During the study, participants will be monitored for the occurrence of cardiovascular events including myocardial infarction, stroke, urgent coronary revascularization, cardiovascular death, major adverse limb events, and all-cause mortality. Researchers will assess these events through regular follow-up visits up to approximately 54 months. The study includes detailed safety monitoring and outcome evaluations to understand the effects of AZD0780 compared to placebo in this population at risk for cardiovascular events.

Researchers are studying pirtobrutinib, an oral drug, to understand how well it works and how safe it is for people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The study focuses on participants who have previously received 1 to 3 treatments, including a covalent Bruton tyrosine kinase (BTK) inhibitor, as well as those with treatment-nafve CLL/SLL who have a specific genetic change called 17p deletion. This is a Phase 2 open-label trial sponsored by Loxo Oncology, Inc. The study has two parts. Part 1 tests three different dose levels of pirtobrutinib in participants with relapsed or refractory CLL/SLL who have prior treatment experience, lasting about 3 years. Part 2 evaluates pirtobrutinib alone in participants who have not received prior treatment but have the 17p deletion, with participation lasting up to 2 years. All doses are given orally. Participants will take the study drug orally and attend visits for up to 3 years in Part 1 or up to 2 years in Part 2. Researchers will monitor how well the disease responds to treatment using overall response rate and how long the response lasts. Safety will be tracked throughout. Participants' ability to swallow oral medication and their overall health status will be assessed before and during the study to ensure suitability and safety.

Researchers are investigating the best way to combine chemotherapy and radiation therapy for patients aged 3 to 29 years with localized non-germinomatous germ cell tumors (NGGCT) in the brain. This phase II trial aims to optimize treatment based on how well the tumor responds to initial chemotherapy, with the goal of reducing spinal cord relapses and adjusting therapy for better disease control. The study also compares different radiation types and examines cognitive and physical effects in children and young adults with NGGCT. Participants first receive induction chemotherapy consisting of carboplatin, etoposide, and ifosfamide over six cycles every 21 days. Based on tumor response, patients are assigned to one of two plans: Plan A involves whole ventricular plus spinal canal irradiation (WVSCI), delivered daily for 6 weeks, while Plan B includes high-dose chemotherapy with stem cell transplant followed by radiation therapy to the whole brain and spine. Some patients may undergo second-look surgery depending on tumor response before continuing treatment. Throughout the study, participants undergo MRI scans, collection of cerebrospinal fluid and blood samples, and questionnaires assessing cognitive, social, and behavioral functioning. Researchers monitor tumor response, progression-free survival, overall survival, and patterns of disease recurrence for up to 10 years. Safety and side effects are also evaluated to better understand long-term outcomes of these treatment approaches.

Researchers are evaluating elritercept (TAK-226, KER-050), an investigational drug, for treating anemia in adults with very low, low, or intermediate risk myelodysplastic syndromes (MDS) who need regular red blood cell (RBC) transfusions. The study is a Phase 3, randomized, double-blind, placebo-controlled trial designed to assess how well elritercept reduces the need for RBC transfusions and to evaluate its safety and tolerability over time. Participants will be randomly assigned in a 2:1 ratio to receive either elritercept or a matching placebo, both given as subcutaneous injections every 4 weeks. The study includes a Primary Phase lasting 24 weeks and a Secondary Phase lasting an additional 24 weeks, during which participants continue their assigned treatments. Eligible participants may also enter an Extension Phase to continue treatment until individual discontinuation or study unblinding. After treatment ends, a Safety Follow-Up Period of 8 weeks and a long-term follow-up lasting up to 5 years will monitor participants. During the study, participants will have visits approximately every 2 weeks initially, then every 4 weeks, to assess treatment effects and safety. Researchers will evaluate the percentage of participants achieving transfusion independence and monitor adverse events, laboratory values, vital signs, and heart tests. Long-term follow-up will continue through regular check-ins for up to five years or until the participant withdraws or the study ends.

Researchers are evaluating the safety, tolerability, and effects of ORX750 in adults with Narcolepsy Type 1 (NT1), Narcolepsy Type 2 (NT2), and Idiopathic Hypersomnia (IH). These rare conditions cause excessive daytime sleepiness and affect daily activities such as school, work, and driving. The study aims to understand how ORX750, which mimics the brain protein orexin that helps maintain wakefulness, impacts sleepiness and other symptoms in these conditions. Participants will receive either ORX750 capsules or matching placebo capsules in a randomized, double-blind setup. The study assesses multiple groups: those with NT1, NT2, and IH. The treatment and monitoring will occur over a period of up to 35 days, including evaluation of plasma drug levels and sleepiness measures. During the study, participants will undergo safety assessments including monitoring for adverse events, laboratory tests, vital signs, ECGs, and suicidal ideation screening up to day 35. Researchers will also measure sleepiness using the Maintenance of Wakefulness Test and the Epworth Sleepiness Scale. The total study duration for each participant is about five weeks, with careful observation of how the body processes ORX750 and its effects on daytime alertness.

Researchers are evaluating the combination of nivolumab and blinatumomab compared to blinatumomab alone in patients aged 1 to under 31 years with first relapse of CD19+ B-cell acute lymphoblastic leukemia (B-ALL), including those with Down syndrome. This phase II trial aims to compare event-free survival and remission rates, as well as assess safety and tolerability of these treatments in this patient group. Treatment involves several groups and arms with different combinations of drugs including dexamethasone, blinatumomab, nivolumab, methotrexate, and others. Some groups receive pre-immunotherapy treatments depending on disease characteristics. Treatment cycles last about 36 to 37 days and may repeat up to two cycles unless disease progression or unacceptable toxicity occurs. Radiation therapy and various chemotherapy regimens are also part of the treatment for certain patients. Participants undergo lumbar punctures, bone marrow biopsies and aspirations, and collections of blood, urine, and cerebrospinal fluid throughout the study. After treatment completion, they are followed up every 3 months for 1 year. The main results measured include minimal residual disease-negative remission rates and event-free survival. Safety, adverse events, and other clinical factors are closely monitored during and after treatment.

Researchers are evaluating solrikitug, a biological treatment, in people with chronic obstructive pulmonary disease (COPD) to assess its safety, tolerability, and how the body processes and responds to the drug. This 12-week, randomized, double-blind, placebo-controlled Phase 2 study aims to understand the effects of two different doses of solrikitug compared to a placebo, all given alongside standard COPD treatments. The study will enroll about 171 participants diagnosed with COPD who have elevated blood eosinophil levels. Participants will be randomly assigned to receive either a high dose or low dose of solrikitug or a placebo, delivered by subcutaneous injection at the study sites over a 12-week treatment period. After the treatment phase, there will be a 16-week follow-up period to monitor longer-term effects and safety. The injections are given under medical supervision during scheduled visits. During the study, participants will undergo assessments including blood tests to measure eosinophil counts and lung function tests such as FEV1. Researchers will track adverse events and serious adverse events throughout the treatment and follow-up periods. The total participation time will be approximately 28 weeks, including treatment and post-treatment observation.

Researchers are evaluating CD388, a long-acting antiviral treatment, to prevent symptomatic influenza infections in adults and adolescents at higher risk for influenza complications. This Phase 3, randomized, double-blind, placebo-controlled study aims to assess how well CD388 works compared to placebo, as well as its safety and tolerability. Participants are randomly assigned to receive either a single dose of 450 mg CD388 or a matching placebo, both given by three subcutaneous injections. The study is conducted across multiple centers and includes participants aged 12 years and older. The trial compares the incidence of influenza-like illness starting from 7 days after dosing up to 24 weeks later. During the study, participants undergo screening tests including rapid antigen tests for influenza and COVID-19 before dosing. Researchers monitor participants for influenza-like illness, collect blood samples at several visits to measure CD388 levels and immune responses, and record any side effects. The overall participation lasts up to about 24 weeks, during which adherence to study procedures and safety are closely followed.
