Researchers are assessing the safety and effects of Ritlecitinib, a study medicine, for treating hidradenitis suppurativa (HS), a condition causing long-lasting, painful red skin lumps. This phase 2 study focuses on adults with moderate to severe HS who have not responded well to or cannot tolerate antibiotics. The goal is to compare experiences and outcomes between those receiving Ritlecitinib and those receiving a placebo. Participants will be randomly assigned to take either Ritlecitinib or a placebo pill once daily at home. The treatment involves an initial loading dose of Ritlecitinib for 8 weeks, followed by an 8-week maintenance dose, totaling 16 weeks of treatment. The placebo group will receive a matching pill with no active medicine. Over approximately 24 weeks, including screening and follow-up, participants will attend around 10 clinic visits for health evaluations, including physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. They will also track their medication intake and HS symptoms daily using an electronic diary on a mobile phone. The study will measure how many patients achieve at least a 50% improvement in HS symptoms by week 16 to evaluate treatment response and safety.

Researchers are evaluating the safety, how the body processes, and effects on body weight of the investigational drug CRB-913 in participants with obesity. This Phase 1b study includes two parts: Part 1 focuses on healthy adults to measure drug levels in the blood after a single dose, while Part 2 involves obese participants to assess safety and weight effects using different doses compared to placebo. Part 2 is blinded so that participants, doctors, and the sponsor do not know who receives the drug or placebo. In Part 1, healthy adults receive a single dose of CRB-913 tablets to study how much of the drug enters the bloodstream and how long it stays. In Part 2, obese participants take one of three doses of CRB-913 or placebo once daily for 12 weeks. After treatment ends, participants are monitored for 28 days. The study includes a randomized, double-blind, placebo-controlled design for Part 2. Participants will attend study visits for drug administration, safety assessments, and blood tests to measure drug levels and effects on body weight. Researchers will monitor for side effects and adverse events from the first dose through 28 days after final dosing. The total participation time includes the 12-week treatment period plus the 28-day follow-up phase to evaluate safety and drug behavior in the body.

Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation (CIC) in this 26-week phase 3 study. The study is randomized, double-blind, and placebo-controlled, involving multiple centers. It aims to compare three doses of tenapanor (5 mg, 25 mg, and 50 mg taken twice daily) against a placebo, with a focus on improving spontaneous bowel movements. Participants will first undergo a 2-week screening where their eligibility is assessed through medical history, physical exams, lab tests, ECG, and self-reported constipation symptoms using an electronic diary (eDiary). Eligible patients will then be randomly assigned to receive one of the three doses of tenapanor or placebo twice daily for 26 weeks. During this treatment period, patients will continue daily and weekly symptom reporting via the eDiary and attend regular safety visits at weeks 2, 4, 8, 12, 16, 20, and 26. After completing the 26-week treatment, patients enter a 4-week treatment-free safety follow-up period to monitor any adverse events. A final visit occurs at the end of this follow-up to assess safety. The main outcome measured is the durable complete spontaneous bowel movements response over 12 weeks. Overall, the study involves careful monitoring of symptoms, safety, and treatment effects over approximately 32 weeks.

Researchers are evaluating whether an investigational drug called OHB-607 can prevent Bronchopulmonary Dysplasia (BPD), a common chronic lung disease, in extremely premature infants. The study compares infants receiving OHB-607 alongside standard neonatal care to those receiving standard care alone to reduce the burden of this lung condition. This is a Phase 2b, multicenter, randomized, open-label study focused on safety and clinical efficacy. Participants will receive an intravenous infusion of OHB-607 from birth until reaching a postmenstrual age (PMA) of 29 weeks and 6 days. The study includes two arms: one group receives the investigational drug plus standard care, while the other group receives only standard neonatal care. The treatment period ends at 29 weeks plus 6 days PMA, after which infants are monitored. Throughout the study, researchers will track the incidence of severe BPD or death up to 36 weeks PMA, whichever occurs first. Assessments will include clinical evaluations and monitoring for safety and any side effects. The study also involves long-term follow-up to observe the infants' health outcomes beyond the treatment period. Participation involves consent from parents and collection of birth and medical history information.

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 studying a medicine called enlicitide to reduce low-density lipoprotein cholesterol (LDL-C) in adults with high cholesterol (hyperlipidemia). This trial aims to find out if taking enlicitide together with rosuvastatin, a standard cholesterol-lowering drug, works better than a placebo in lowering LDL-C levels. The study is a Phase 3 trial that is randomized, double-blind, and placebo-controlled to ensure accurate and unbiased results. Participants will receive oral tablets of enlicitide or placebo along with oral capsules of rosuvastatin or placebo. The study compares the effect of enlicitide plus rosuvastatin against placebo to evaluate their impact on LDL-C. The treatment period lasts 8 weeks, during which participants take their assigned medications as directed. During the study, researchers will measure the average percent change in LDL-C from the start of the trial to week 8. Participants will be monitored for safety and any side effects throughout the study. The total participation time includes screening, treatment, and follow-up assessments to evaluate the medicines' effects and safety in adults aged 18 to 64 with hyperlipidemia.

Researchers are evaluating molnupiravir, a study medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 more effectively than a placebo. This Phase 3 randomized, placebo-controlled, double-blind study focuses on non-hospitalized adults at high risk of severe disease progression due to COVID-19. The study addresses the need for alternative treatments for people who cannot take certain COVID-19 medications due to availability or potential drug interactions. Participants will receive either molnupiravir or a placebo, both given orally as two 400 mg film-coated tablets every 12 hours for 5 days, totaling 10 doses. Some participants may also receive remdesivir as part of standard care if clinically appropriate and available. The study compares the effects of molnupiravir with placebo in preventing severe illness outcomes. Throughout the study, participants will be monitored for outcomes such as hospitalization, death, or medically attended visits related to COVID-19 up to 29 days. Safety is assessed by tracking adverse events for up to about 5 months and discontinuation of study treatment due to adverse events for about 5 days. The study involves laboratory tests, symptom assessments, and safety evaluations to understand molnupiravir's impact on disease progression and participant health.

Researchers are evaluating a new vaccine called V118C designed to prevent pneumococcal disease, which includes infections caused by the Streptococcus pneumoniae bacteria. This study focuses on toddlers and infants to understand the safety and tolerance of V118C. It is a Phase 1 trial that compares V118C to an existing pneumococcal vaccine called PCV20 in children. The study has two parts: Stage 1 involves toddlers aged 12 to 15 months who have already received three doses of PCV20 during infancy. Stage 2 involves infants around 2 months old who will receive four doses of V118C using a 3+1 schedule (three infant doses plus one toddler dose). Both vaccines are given by intramuscular injection. The study compares safety and immune response between V118C and PCV20. Participants will be monitored for immediate reactions within 30 minutes after vaccination and for local and systemic side effects up to 7 days post-vaccination. Unsolicited adverse events will be tracked up to 28 days, and serious or medically attended events will be assessed for up to 12 months after vaccination. The study aims to collect detailed safety and tolerability information over this period.

Researchers are evaluating new treatment options for women with relapsed high-grade serous ovarian cancer, a fast-growing cancer that starts in the cells covering the ovaries, lining of the belly, or fallopian tubes. This study focuses on people whose cancer has returned after prior platinum-based chemotherapy. The goal is to assess the safety, tolerability, and effectiveness of a new antibody drug conjugate called raludotatug deruxtecan (R-DXd), alone or combined with other anticancer treatments, in this patient group. The study has two parts: Part 1 is a dose escalation phase to find the recommended dose of R-DXd, and Part 2 is an expansion phase using that dose. R-DXd is given as an intravenous infusion on Day 1 of every 3-week cycle. Other treatments that may be given include carboplatin and paclitaxel (each up to 6 cycles), bevacizumab every 3 weeks, pembrolizumab up to 35 cycles, gemcitabine on Days 1 and 8 of each 3-week cycle, and pegylated liposomal doxorubicin every 4 weeks. Rescue medications to control side effects are also administered according to protocol. Participants will be monitored for adverse events, dose-limiting toxicities, and treatment discontinuations up to about 3 years. Researchers will measure cancer response using established criteria and assess safety through clinical exams, imaging, and laboratory tests. Eligibility includes having measurable disease and adequate health status. The study includes long-term follow-up to track treatment effects and safety outcomes over time.

Researchers are evaluating sotatercept as a potential treatment for pulmonary arterial hypertension (PAH), a condition where blood vessels in the lungs thicken and narrow, causing high blood pressure in the lungs and overworking the heart. PAH symptoms include difficulty breathing and reduced ability to be active. Current standard treatments address symptoms but do not stop disease progression. This Phase 3 study focuses on the long-term safety and tolerability of sotatercept when added to standard PAH therapy. Participants in this long-term follow-up study receive sotatercept through subcutaneous injections every three weeks. Only individuals who completed prior sotatercept PAH studies without early discontinuation may join. This study continues the observation and assessment of participants over an extended period to learn about the effects and safety of sotatercept combined with background PAH treatments. During the study, participants will be regularly monitored for adverse events, treatment discontinuations, and the presence of anti-drug antibodies for up to approximately 90 months. Laboratory tests will evaluate blood components such as platelets, hemoglobin, creatinine, bilirubin, and liver enzymes. Changes from baseline in body weight, blood pressure, and electrocardiogram readings will also be tracked. The study involves adherence to visit schedules and compliance with study procedures to ensure comprehensive long-term safety data collection.
