Researchers are evaluating the safety and effectiveness of elenestinib BLU-263 combined with symptom directed therapy SDT compared to placebo plus SDT in adults with indolent systemic mastocytosis ISM whose symptoms are not well controlled by SDT alone. This randomized, double-blind, placebo-controlled Phase 23 study includes multiple parts to assess different doses and durations of elenestinib treatment, including an open-label extension for participants finishing earlier phases. The study also enrolls participants who have previously received an approved selective KIT inhibitor and includes pharmacokinetic groups. Participants receive oral elenestinib or placebo once daily alongside SDT, which is personalized based on individual symptom management needs. Part 1 focuses on short-term treatment lasting up to 12 weeks, while Part 2 extends treatment to approximately 48 weeks. Part 3 and other parts allow treatment for up to about 5 years. The study monitors participants through these phases to evaluate how elenestinib affects symptoms, disease markers, and safety over time. During the study, participants undergo regular assessments of symptoms using the ISM-Symptom Assessment Form ISM-SAF, laboratory tests including serum tryptase and KIT D816V allele levels, bone marrow evaluations, and quality of life measures. Researchers track adverse events and changes in disease-related factors at various points up to 5 years. This thorough monitoring helps measure treatment effects and safety over both short and long-term periods, with total participation lasting several years depending on the study part.

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.

Researchers are studying patients with endogenous Cushing syndrome to understand how often adrenal insufficiency occurs when treated with osilodrostat combined with glucocorticoid replacement. The study also examines new steroid biomarkers to monitor osilodrostat dosing, and assesses treatment durability, safety, and clinical improvement. This observational study aims to provide important insights into managing this condition with a block-and-replace approach. The study has two phases. In Phase 1 Titration, participants start with a low dose of osilodrostat and add methylprednisolone replacement. Doses are adjusted to reach specific cortisol level goals, with frequent monitoring and communication. Once these goals are met, participants enter Phase 2 Maintenance, where they continue treatment for 48 weeks with periodic cortisol tests to track treatment effects. Participants will regularly provide blood and saliva samples for cortisol and steroid profiling, and report symptoms related to adrenal insufficiency. Researchers will track clinical measures such as blood pressure, weight, and quality of life over about 48 weeks. The main outcome is the percentage of participants experiencing adrenal insufficiency during Phase 1, along with various secondary health and hormone measures throughout the study.

Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

This research investigates treatments for metastatic castration-resistant prostate cancer mCRPC focusing on a drug called ifinatamab deruxtecan I-DXd. The study aims to assess the safety, how well participants tolerate the treatments, and appropriate dosing levels of I-DXd alone or combined with other therapies. Researchers will also monitor participants prostate specific antigen PSA levels during treatment to understand its effects. Participants are assigned to one of several treatment groups. One group receives docetaxel every three weeks for up to 10 cycles. Other groups receive I-DXd alone or combined with either opevesostat or androgen receptor pathway inhibitors such as abiraterone acetate or enzalutamide. I-DXd is given every three weeks until unacceptable side effects, disease progression, death, or withdrawal, while the other drugs continue until specific discontinuation criteria are met. Premedication is required before each I-DXd dose to prevent nausea and vomiting. Throughout the study, participants undergo various assessments including monitoring of dose-limiting toxicities, adverse events, and PSA response rates. Researchers also track objective response rates, progression-free survival, overall survival, and other clinical outcomes over up to approximately 54 months. The study involves regular evaluations to assess safety and treatment effects until study completion.

Researchers are evaluating letermovir in children and adolescents under 18 years old who weigh less than 40 kilograms and have received a kidney transplant. The study aims to understand how letermovir behaves in the body over time and to assess its safety and how well participants tolerate it. This phase 1, open-label study focuses on cytomegalovirus CMV prevention in this specific pediatric transplant population. Participants who are between 4 and 52 weeks post-kidney transplant will receive letermovir either orally as tablets or pellets, or through a gastrostomy or nasogastric tube as pellets, for 7 consecutive days. The dosing is adjusted based on weight bands. This is a single-group study without a placebo or comparator arm. During the study, participants will be closely monitored through blood samples to measure drug levels and CMV DNA, including the primary outcome of the drug concentration area under the curve over 24 hours on Day 7.

This part includes two cohorts and lasts up to 52 weeks. Participants will be closely monitored through the study with assessments of seizure frequency, cognitive and adaptive behavior changes using tools like the Bayley-4 and Vineland-3 scales, and clinical global impressions over 52 weeks. Safety and effectiveness are evaluated by comparing seizure counts before and after dosing. The study includes various cognitive and behavioral outcome measures and follows participants from dosing up to one year for treatment effects and safety observations.

This research aims to evaluate a new program called Strengthening COnnections to Overcome Pain SCOOP designed for older adults living in rural areas who experience chronic pain and loneliness. The study seeks to find out if participating in SCOOP reduces how much pain interferes with daily life and decreases feelings of loneliness, while also measuring participant engagement in the program. The SCOOP program lasts 7 weeks and is delivered mainly over the telephone by community health workers. Participants in the SCOOP group will watch brief weekly videos teaching strategies for managing pain and improving social connections, followed by coaching sessions with a community health worker to support behavioral goal-setting and connect participants to helpful resources. A control group will receive usual care and later be offered educational materials and a workshop. Participants will complete two telephone interviews one at the start of the study and another 8 weeks later to assess changes in pain interference, loneliness, and satisfaction with the program. Researchers will track how many coaching sessions are completed as a measure of engagement. The total participation spans the 7-week intervention period plus follow-up assessments, with the study concluding in May 2027.
