Researchers are evaluating the safety and effectiveness of elenestinib (BLU-263) combined with symptom-directed therapy (SDT) compared to placebo plus SDT in people with indolent systemic mastocytosis (ISM) whose symptoms are not well controlled by SDT alone. This Phase 2/3 randomized, double-blind, placebo-controlled study includes participants with ISM and smoldering systemic mastocytosis, and also involves groups for pharmacokinetic studies and participants who previously received a selective KIT inhibitor. The study is divided into multiple parts. Parts 1 and 2 enroll participants with ISM who will receive either elenestinib oral tablets or placebo alongside their symptom-directed therapy. Participants from Part 2 may continue into Part 3, which is an open-label extension where all receive elenestinib. Part K enrolls participants with ISM who have prior experience with selective KIT inhibitors. The study tracks treatment effects and safety over time. Participants will be monitored for up to 5 years, with assessments including the number of treatment-emergent adverse events, changes in symptom scores measured by the ISM-Symptom in Assessment Form, and overall safety monitoring. Evaluations occur at baseline, 13 weeks, 49 weeks, and throughout the long-term follow-up. The study also includes detailed tracking of symptom control and adverse events to evaluate the impact of treatment on participants' health and quality of life.

Researchers are studying advanced renal cell carcinoma (RCC) that has returned after prior adjuvant therapy. The trial aims to find out if treatment with belzutifan and zanzalintinib helps patients live longer and delays disease progression compared to treatment with cabozantinib. This is a Phase 3 randomized study focusing on participants with recurrent advanced RCC who have previously received anti-PD-1/L1 therapy. Participants are randomly assigned to receive one of two oral drug regimens: either belzutifan combined with zanzalintinib, both taken once daily, or cabozantinib alone, also taken once daily. The study compares these treatments to assess their effects on disease control and overall survival. During the study, participants will be monitored for progression-free survival and overall survival for up to approximately 73 months. Researchers will evaluate how well the cancer responds to treatment and track any changes in health status over time. Safety and effectiveness of the treatments will be closely followed throughout the study period.

Researchers are evaluating a new treatment called ifinatamab deruxtecan (I-DXd) for men with metastatic castration-resistant prostate cancer (mCRPC). This study compares I-DXd to chemotherapy to see if it helps people live longer overall and live longer without their cancer worsening. It is a Phase 3, open-label trial focused on patients who have progressed on prior therapies and have evidence of metastatic disease. Participants receive either I-DXd through an intravenous infusion every 3 weeks or docetaxel chemotherapy administered every 3 weeks. Prednisone tablets are also given daily as part of the treatment plan. Before each I-DXd dose, premedication is provided to help prevent nausea and vomiting using a combination of drugs such as corticosteroids and anti-nausea medicines. Treatment continues until disease progression, unacceptable side effects, or other reasons to stop. During the study, researchers monitor overall survival and how long patients live without their cancer progressing, for up to about 36 months. Participants undergo tumor tissue collection, scans, and assessments to track disease status and side effects. Safety is closely watched throughout treatment. The study includes men aged 18 and older with confirmed prostate cancer and metastatic disease who have previously received certain hormone therapies but no prior taxane chemotherapy for mCRPC.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread from the cervix to other parts of the body. This Phase 3 study aims to evaluate the safety and effectiveness of combining sacituzumab tirumotecan (sac-TMT), an antibody drug that targets cancer cells, with pembrolizumab and bevacizumab. The study seeks to find out if this combination can help people live longer or keep their cancer from worsening compared to standard treatments. The study has two parts. In Part 1, participants receive sac-TMT together with pembrolizumab and bevacizumab to assess safety. In Part 2, after standard initial treatment, those whose cancer does not progress will be randomly assigned to maintenance treatment with either pembrolizumab alone or sac-TMT plus pembrolizumab. Bevacizumab may be added during maintenance treatment based on the doctor's decision. All treatments are given through intravenous infusions, and participants may receive rescue medications to manage side effects before sac-TMT infusion. Participants will be monitored for adverse events and treatment tolerability over several months. The study measures include progression-free survival and overall survival, assessed by independent review. Safety and treatment continuation rates are tracked during Part 1 for up to approximately 66-69 months, while Part 2 outcome measures extend up to 48-60 months. Various assessments, including laboratory tests and evaluations of cancer status, will be performed throughout the study to understand treatment effects and participant well-being.

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.

Researchers are investigating treatments for women with recurrent endometrial cancer that expresses different levels of the HER2 protein. The study has two groups based on the tumor's HER2 score: Cohort 1 includes patients with HER2 IHC 1+ or 2+ who have previously received immune checkpoint inhibitors and platinum-based chemotherapy, while Cohort 2 includes patients with HER2 IHC 3+. The purpose is to compare the effectiveness and safety of the investigational drug BNT323 (also called DB-1303) against chemotherapy in Cohort 1 and to evaluate BNT323 alone in Cohort 2. The study also looks at how the drug affects the immune system, the body's handling of the drug, quality of life, and potential side effects. Participants in Cohort 1 are randomly assigned to receive either BNT323 via intravenous infusion or a chemotherapy drug chosen by the investigator (doxorubicin, paclitaxel, or docetaxel if paclitaxel is unsuitable). Treatment continues until the cancer progresses, unacceptable side effects occur, or the participant withdraws consent. Those in Cohort 2 receive BNT323 alone until disease progression or other discontinuation criteria are met. The study includes a screening period, a treatment period expected to last about six months, followed by safety monitoring, efficacy follow-up, and long-term survival follow-up lasting up to approximately 53 months. During the study, participants undergo regular assessments including imaging scans to measure tumor response by RECIST criteria, safety monitoring for adverse effects, and evaluations of quality of life. Researchers also study the pharmacokinetics of BNT323 and the immune response. The main outcomes measured are progression-free survival in Cohort 1 and objective response rate in Cohort 2. Safety follow-up ensures ongoing monitoring after treatment to evaluate longer-term effects and participant wellbeing.

Researchers are assessing the safety and effects of marstacimab as a potential treatment for hemophilia in children aged 1 to 17 years. This study includes pediatric participants with severe Hemophilia A or moderately severe to severe Hemophilia B, with or without inhibitors. Enrollment will occur in stages, starting with adolescents aged 12 to 17 years, followed by children aged 6 to 11 years, and finally those aged 1 to 5 years. Participants must have detailed historical records of their hemophilia treatment and bleeding events for at least one year prior to joining the study. All participants will receive marstacimab once weekly by subcutaneous injection, with the first dose given at the study site by staff. During the 12-month treatment period, weekly injections may be administered at home or at the study site based on preference. The study compares participant experiences during treatment with their historical records before starting marstacimab to evaluate its potential to prevent bleeding episodes common in hemophilia. Participants will be involved for about 14 months, including a 1-month screening period, 12 months of treatment, and a 1-month follow-up. They will visit the study site at least 10 times, with the option for two visits to be conducted at home if local rules allow. Additionally, six telephone calls will be scheduled every two months. Researchers will monitor bleeding rates, adverse events, thrombotic events, immune responses, injection site reactions, and hypersensitivity throughout the study period.

Researchers are evaluating the effectiveness and safety of Xeomin injections in preventing chronic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections given into muscles of the head and neck. Participants have chronic migraine diagnosed for at least 12 months and meet specific headache and migraine day criteria. The study aims to measure changes in monthly migraine days over time with Xeomin treatment. Participants will receive four treatments spaced about 12 weeks apart over a total study duration of 52 to 55 weeks. The treatments involve injections of either Xeomin or placebo solution prepared with sodium chloride. Visits occur approximately every 4 weeks, totaling 14 visits: the first, last, and four treatment visits are on-site, while the other eight visits are remote via phone or video call. During the study, participants will keep headache diaries to track migraine and headache days. Researchers will focus on the change in monthly migraine days from baseline to six months after the first injection. Safety and effectiveness are monitored throughout, with frequent assessments during both on-site and remote visits to ensure accurate tracking of migraine symptoms and any side effects.

Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing episodic migraine. This phase 3 clinical trial focuses on adults who experience episodic migraine, aiming to measure changes in the number of migraine days per month. Participants must have a diagnosis of episodic migraine for at least 12 months and meet specific headache frequency criteria. Participants will receive four treatments of either Xeomin or placebo injections into muscles of the head and neck, with treatments spaced about 12 weeks apart. The entire trial lasts approximately 52 to 55 weeks, beginning with a screening period of 4 to 5 weeks. There are about 14 visits in total, with the first, last, and four treatment visits conducted on-site, while the other visits are held remotely via phone or video. Throughout the study, participants will track their migraine days using a headache diary, and researchers will assess changes in monthly migraine frequency from baseline to six months after the first injection. Regular monitoring includes both in-person and remote assessments. The primary outcome focuses on the change in monthly migraine days between baseline and month six after treatment initiation.

Researchers are evaluating the safety and potential benefits of VHB937 in people aged 50 to 85 years with early Alzheimer's disease, including those diagnosed with Mild Cognitive Impairment due to Alzheimer's or mild Alzheimer's disease. This Phase II, multicenter, randomized, double-blind, placebo-controlled study aims to assess how VHB937 affects memory, thinking abilities, daily activities, and brain changes, while also studying how the body processes and responds to the treatment. The study includes an initial 72-week double-blind phase followed by an extension period. Participants will receive either VHB937 solution for infusion or a placebo solution through infusion during the 72-week double-blind phase. The study compares these two groups to evaluate the effects and safety of VHB937 in early Alzheimer's disease. After the double-blind phase, participants may continue in an extension period for further observation. Treatment involves regular infusions under controlled conditions throughout the study. During the study, participants and their study partners will attend visits for assessments including memory and cognitive tests, evaluations of daily functioning, brain imaging, and biomarker analysis from cerebrospinal fluid or PET scans. Researchers will monitor safety, record any side effects, and track changes using the Clinical Dementia Rating scale (CDR) over 72 weeks. The study requires a reliable partner to accompany participants to visits, and overall participation includes monitoring during treatment and the extension phase to thoroughly assess VHB937's effects and safety.
