Researchers are investigating the similarity in pharmacokinetic (PK) profile, effectiveness, safety, and immune response of HLX17 compared to US-sourced Keytruda® in patients who have had surgery for non-small cell lung cancer, melanoma, or renal cell carcinoma. This Phase I, multicenter, randomized, double-blind study aims to compare these two treatments in people with these resected solid tumors to better understand their performance and safety profiles. Participants will receive either HLX17 or US-sourced Keytruda®, each given at a dose of 200 mg on the first day of every 3-week cycle. The study is designed with parallel groups, where each participant receives one of the treatments across multiple cycles. The dosing schedule continues through six cycles, and the two treatments are directly compared under controlled conditions. Throughout the study, participants will be monitored closely with various assessments including laboratory tests and evaluations of organ function to ensure safety. The main outcomes measured are drug exposure over time from the first dose to 21 days after the initial and sixth doses. Participants are expected to have a performance status of 0 and a life expectancy of at least 12 weeks. Safety and immunogenicity will also be evaluated, with follow-up to monitor any side effects or immune responses during and after treatment.

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 focuses on men with prostate cancer who have previously participated in an enzalutamide clinical study sponsored by Astellas or Medivation. It aims to gather long-term safety information from participants who continue to benefit from enzalutamide treatment. This is a Phase 2 open-label extension study designed to monitor ongoing treatment effects after the initial study has completed its primary analysis or evaluation period. Participants will continue their previous treatment regimens, which may include enzalutamide taken orally once daily. Some may also receive abiraterone acetate with prednisone or leuprolide acetate depending on their prior study enrollment. Dose adjustments are allowed with medical monitor approval. The first visit of this study should occur within seven days of the last visit of the prior study unless treatment is temporarily paused. Participants are asked to return to their study site every 24 weeks for safety reviews, including adverse event monitoring and medication checks. At visits every 12 weeks, participants return unused study drugs and receive new supplies if needed. Safety data, including all adverse events and serious adverse events, are collected from consent until study completion, which may last up to 96 months. The study follows local standard care guidelines and includes a post-marketing phase in South Korea.

Researchers are investigating the effectiveness of dotinurad compared to allopurinol in lowering serum uric acid (sUA) levels in adults with hyperuricemia related to gout. This phase 3, randomized, double-blind trial focuses on adults aged 18 to 75 who have had gout for at least one year and experienced multiple gout flares in the past year. The study aims to assess the percentage of participants achieving an sUA level below 6.0 mg/dL at 24 weeks. Participants receive either dotinurad or allopurinol as oral over-encapsulated tablets. Allopurinol doses range from 200 mg/day for those with moderate kidney impairment to 600 mg/day, with participants maintaining a stable dose for at least three months before starting the study. The trial includes a 24-week treatment period where the effects of these medications on uric acid levels are monitored and compared. During the study, participants undergo regular assessments including serum uric acid measurements at screening and throughout the 24 weeks. Female participants of childbearing potential have pregnancy tests and must agree to contraception requirements. Researchers monitor safety, treatment adherence, and gout flare history to evaluate the treatments' efficacy and tolerability over the study period.

Researchers are evaluating the effectiveness of dotinurad compared to allopurinol in lowering serum uric acid (sUA) levels at 24 weeks in adults with tophaceous gout. This condition involves the presence of measurable tophi, or deposits of uric acid crystals, in joints such as hands, wrists, feet, or ankles. The study is a Phase 3, randomized, double-blind, multicenter trial focused on adults aged 18 to 75 years who have had gout for at least one year. Participants receive either dotinurad or allopurinol in over-encapsulated tablet form, taken orally. The treatments are compared to see which better lowers sUA levels below 5.0 mg/dL after 24 weeks. The study includes a screening period before treatment begins, during which eligibility is confirmed, including measurements of tophi size and uric acid levels. During the study, participants will have regular assessments to monitor serum uric acid levels and the size of tophi. Safety and side effects will also be monitored throughout the 24-week treatment period. The main outcome is the percentage of participants who achieve sUA levels less than 5.0 mg/dL at week 24, helping to understand the comparative efficacy and safety of the two medications.

Researchers are studying the immune response and safety of mRNA-1018-H5, a pandemic influenza vaccine, in adults aged 18 years and older. The trial aims to assess how well two doses of this vaccine trigger antibody production and to monitor any side effects or reactions. This is a Phase 3, randomized, observer-blind, placebo-controlled study focused on the influenza virus. Participants will receive either the mRNA-1018-H5 vaccine or a placebo, both provided as sterile liquid injections. The study involves two doses and includes detailed monitoring for immune response and side effects after vaccination. The trial compares the vaccine to a placebo to evaluate its immunogenicity and safety. During the study, individuals will undergo medical evaluations including physical exams and pregnancy testing if applicable. Researchers will measure antibody levels at Day 43 and record any local or systemic reactions up to Day 29 after injections, as well as any adverse events up to Day 205. The study tracks serious and medically-attended adverse events to ensure careful safety monitoring throughout the participation period.

Researchers are evaluating rapcabtagene autoleucel, a biological treatment given as a single infusion after lymphodepletion, in adults with active, refractory systemic lupus erythematosus (SLE) or active, refractory lupus nephritis (LN). This Phase 2, open-label study aims to assess both the effectiveness and safety of this therapy in patients who have not responded well to at least two previous treatments. Participants must meet specific criteria including positive autoantibody tests and active disease symptoms measured by the SLEDAI-2K score. Participants will receive one infusion of rapcabtagene autoleucel following preparatory lymphodepletion therapy. The study does not mention comparator groups, focusing on monitoring responses to this single treatment. Treatment effects will be evaluated at 24 and 52 weeks after infusion to understand how well the therapy works over time. Throughout the study, participants will be closely monitored with various assessments to evaluate disease activity, safety, and response to treatment. Researchers will use laboratory tests, including autoantibody levels, and clinical evaluations to track changes in disease status. Safety monitoring will continue during the study period to identify any adverse effects. The total participation duration covers at least 52 weeks to capture both short-term and longer-term outcomes of the therapy.

Researchers are evaluating the safety, effectiveness, and how the body processes etrasimod in treating adolescents aged 12 to under 18 years with moderately to severely active ulcerative colitis. This phase 2 study aims to understand the impact of this treatment on this younger population. Participants who complete the initial 52-week treatment may continue in a long-term extension period lasting up to 4 additional years, totaling 5 years after enrollment. Participants will take etrasimod orally once daily as either a tablet or granules for up to 52 weeks. After this treatment period, those who finish may opt to join a long-term extension to continue treatment and monitoring. The study is open-label and single-arm, meaning all participants receive the study drug and both effects and safety are observed over time. During the study, researchers will regularly assess participants' health, focusing on the proportion achieving clinical remission based on the Modified Mayo Score at week 52. Monitoring includes tracking safety, drug levels in the body, and overall treatment effects. The extended monitoring in the long-term extension allows for continued evaluation of safety and effectiveness over several years.

Researchers are evaluating how effective, safe, and tolerable a vaccine for Clostridioides difficile (C. difficile) infection is in adults aged 65 years and older. The study focuses on reducing the number of C. difficile infections, which can cause diarrhea, in this older adult population. This is a Phase 3, placebo-controlled, double-blinded, randomized trial involving participants who are at risk because of recent or planned contact with healthcare systems or recent antibiotic use. Participants will receive either the C. difficile vaccine or a saline placebo. Both are given by injection into the upper arm muscle. The study includes 3 planned clinic visits and 3 phone visits initially, followed by yearly clinic visits until the study ends. Participants will remain in the study until enough infection events have occurred—this period may last up to about three and a half years, but could be shorter or longer depending on how quickly events happen or if the study stops early due to clear results. Throughout the study, participants will report any side effects such as local reactions and systemic events for 7 days after each vaccination, and adverse events for up to one month. Serious adverse events are monitored for up to 18 months after the last dose. If participants experience 3 or more loose stools within 24 hours during the study, they must save the next stool and contact the study team for infection testing. This ongoing monitoring helps assess the vaccine's impact on preventing medically attended C. difficile infections over time.

Researchers are studying the effects of felzartamab, a laboratory-made antibody, in adults who have received kidney transplants and are experiencing antibody-mediated rejection (AMR). AMR happens when the immune system mistakenly attacks the new kidney, causing damage that can lead to organ failure. This phase 3 trial aims to compare felzartamab to a placebo to see how well it helps treat AMR in kidney transplant patients. The study focuses on how many participants have kidney tissue that looks normal or nearly normal after 24 weeks of treatment. Participants will be randomly assigned to receive up to 9 doses of either felzartamab or a placebo through an intravenous infusion based on their body weight during the first part of the study, which lasts up to 24 weeks and is double-blind. In the second part, lasting up to 28 weeks, all participants will receive felzartamab in an open-label phase where everyone knows the treatment being given. In total, participants will have up to 21 study visits over about one year. During the study, participants will undergo kidney biopsies, blood and urine tests, electrocardiograms, and other assessments to monitor kidney function, immune response, and safety. Researchers will measure how long the transplanted kidney works, changes in antibody levels, signs of rejection, and side effects. The study also monitors how felzartamab is processed by the body and whether participants develop antibodies against the drug. Screening before enrollment can take up to 42 days.
