Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation CIC. This study is a 26-week, multi-center, randomized, double-blind, placebo-controlled trial followed by a 4-week treatment-free safety follow-up period. It aims to compare three different doses of tenapanor with a placebo taken twice daily to assess their impact on constipation symptoms. The study includes a 2-week screening period to confirm eligibility, followed by a 26-week randomized treatment period where patients receive either 5 mg, 25 mg, or 50 mg of tenapanor twice daily, or a matching placebo. Patients record their constipation symptoms daily in an electronic diary. After the treatment period, there is a 4-week safety follow-up without treatment to monitor any adverse effects. Participants will have regular visits every 2 to 6 weeks for safety checks including medical assessments, vital signs, ECG, and lab tests. Their symptom diaries will be reviewed throughout the study. The main outcome measured is the durable complete spontaneous bowel movements response at 12 weeks. Secondary outcomes include changes in bowel movement frequency, stool consistency, and straining. The total study duration is approximately 32 weeks including all phases.

This trial evaluates the effectiveness of dotinurad compared with allopurinol in lowering serum uric acid levels in adults with gout-related hyperuricemia. The study focuses on reducing uric acid to below 6.0 mgdL after 24 weeks of treatment, addressing a common complication in gout patients. It is a phase 3, randomized, double-blind study involving adult participants aged 18 to 75 years with a history of gout. Participants are randomly assigned to one of three groups one group continues allopurinol at their existing dose once daily through week 64 the second group receives dotinurad starting at 1 mg once daily for the first 4 weeks, then 2 mg once daily through week 64 the third group begins with 1 mg daily for 4 weeks, increases to 2 mg daily for 8 weeks, then continues 4 mg daily through week 64. All treatments are administered orally as over-encapsulated tablets. Throughout the study, participants undergo regular monitoring of serum uric acid levels and gout flares from baseline up to week 68. Assessments include measuring the percentage of participants achieving target uric acid levels at various points, gout flare rates, and treatment-emergent adverse events. The study also evaluates safety and tolerability over the course of the treatment period, which lasts up to approximately 68 weeks including follow-up.

Researchers are evaluating the efficacy of dotinurad compared with allopurinol in lowering serum uric acid sUA levels in adults with tophaceous gout. This Phase 3 trial focuses on adult participants aged 18 to 75 years who have measurable tophi and a diagnosis of gout for at least one year. The study aims to assess how well dotinurad reduces sUA levels at Week 24 compared to allopurinol, an established treatment for this condition. Participants are randomly assigned to one of two treatment groups. One group will stop their current allopurinol and continue with study-supplied allopurinol once daily through Week 76. The other group will discontinue allopurinol and start dotinurad at 1 mg daily for the first 4 weeks, then increase to 2 mg daily for the next 8 weeks, and finally 4 mg daily thereafter until Week 76. Both treatments are given as oral tablets, and participants are closely monitored throughout the study. During the study, participants will undergo various assessments including blood tests to measure serum uric acid levels at multiple time points, evaluation of tophi response, and tracking of gout flare frequency and severity. Safety monitoring will include recording any adverse events and serious side effects up to Week 80. The main outcome measures focus on the percentage of participants achieving target sUA levels at Week 24 and clinical responses in tophi at Week 76, with ongoing evaluations up to Week 80 to assess longer-term effects and safety.

Researchers are studying the safety and effects of two drugs, PF-08653945 and PF-08653944, given alone or together for weight loss in adults with overweight or obesity. This Phase 2b trial compares these drugs to a placebo to better understand their impact on body weight over time. The study is designed to evaluate different doses and combinations of these drugs to find the most effective approach. Participants receive subcutaneous injections of either PF-08653945 alone, PF-08653945 combined with PF-08653944, PF-08653944 alone, or a placebo. The study uses a randomized, double-blind design with multiple cohorts receiving different drug combinations or placebo. Treatments are administered as injections under the skin over a planned period of 48 weeks, with follow-up extending to 70 weeks to monitor safety and outcomes. During the study, participants will have their body weight measured at baseline and regularly through Week 48 and Week 60 to track changes. Researchers will assess the percentage of weight loss and monitor any treatment-emergent or serious adverse events up to Week 70. Participants will attend scheduled visits for injections and evaluations throughout the trial, which lasts for over a year in total.

Researchers are evaluating the efficacy and safety of SPN-812 viloxazine extended release in children aged 4 to 5 years with Attention-DeficitHyperactivity Disorder ADHD. This phase 4 study is randomized, double-blind, placebo-controlled, and involves multiple centers. It aims to assess treatment effects and tolerability in this preschool-age group with ADHD symptoms confirmed by specific diagnostic criteria. Participants will be randomly assigned to receive either 100mg of SPN-812 or a placebo once daily for 6 weeks. The study includes a screening period of up to 4 weeks to determine eligibility. The total study duration for each participant is up to 10 weeks, during which the two groups will be compared to evaluate the impact of the medication versus placebo. During the study, children will be assessed using the Attention-DeficitHyperactivity Disorder Rating Scale, 4th Edition, Preschool Version ADHD-RS-IV-P and the Clinical Global Impression scales to measure symptom severity and change. Safety and tolerability will be monitored throughout. Parents or guardians will provide consent, and children will participate in structured activities to help evaluate their symptoms outside the home. Regular study visits will include clinical evaluations and monitoring over the 6-week treatment period.

Researchers are conducting a Phase 3, double-blind, placebo-controlled, randomized withdrawal study to evaluate the efficacy and safety of AXS-14 esreboxetine in managing fibromyalgia. The study aims to understand how well AXS-14 works for people with fibromyalgia by comparing continued treatment to placebo after an initial response. This multi-center trial is sponsored by Axsome Therapeutics, Inc. The study includes a 12-week open-label period where all participants receive AXS-14 tablets once daily. Those who respond to treatment will then enter a 12-week double-blind, placebo-controlled randomized withdrawal period. During this phase, participants are randomly assigned to either continue AXS-14 or switch to placebo until a loss of therapeutic response occurs or the period ends. Participants will be closely monitored throughout both study periods. Researchers will assess the time from randomization to loss of therapeutic response over 12 weeks. The study involves regular evaluations to track safety and treatment effects. Total participation spans up to 24 weeks, including both treatment phases.
