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 investigating the effects of XYOSTED as a testosterone replacement therapy in adolescent males aged 12 to under 18 years who have primary or secondary hypogonadism. This Phase 3/4, open-label, multicenter study aims to evaluate how well XYOSTED supports puberty continuation or induction, as well as its dosage, safety, and testosterone level outcomes. Participants have a confirmed deficiency or absence of endogenous testosterone and will be assessed for pubertal development and hormone levels before starting treatment. Participants will receive XYOSTED injections with dosages tailored to their weight and targeted Tanner Stage of puberty. Dose adjustments will be made regularly based on serum total testosterone levels measured at specific intervals after dosing, with evaluations approximately every three months to reach desired testosterone levels. After completing the 52-week primary study, participants may join a 24-month long-term safety extension with clinic visits every six months for ongoing clinical, laboratory, and pharmacokinetic assessments. During the study, participants will undergo thorough clinical examinations including pubertal staging, multiple testosterone measurements, and monitoring for safety and pharmacokinetics throughout treatment and extension periods. Researchers will track changes in testosterone levels from enrollment through week 53 and monitor overall safety. The study includes detailed follow-up and dose management to support pubertal development and assess long-term effects of XYOSTED therapy in this population.

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 ways to prevent cytomegalovirus (CMV) infection in children and adolescents who have received a kidney transplant and weigh less than 40 kilograms. This Phase 1 study aims to understand how the drug letermovir behaves in the body over time and to evaluate its safety and tolerability in this young population. Participants receive letermovir orally, either as tablets or pellets, or through a gastrostomy or nasogastric tube if pellets are used. The treatment is given once daily for seven consecutive days. This study is open-label and single-arm, meaning all participants receive the same treatment, and the study monitors them closely throughout this period. During the study, participants will have blood samples collected before the first dose and at several points up to 24 hours after dosing on Day 7 to measure how the drug is processed by the body. Researchers will also monitor kidney function stability, CMV DNA levels, and any side effects to assess safety. The study focuses on children and adolescents younger than 18 years and weighing between 2.5 and less than 40 kilograms, with a total participation time covering at least seven days of treatment and associated assessments.

Researchers are investigating sacituzumab tirumotecan (MK-2870) alone or combined with other treatments to treat certain gastrointestinal cancers. These include colorectal cancer that cannot be removed by surgery or has spread, advanced pancreatic ductal adenocarcinoma, and biliary tract cancer. The study aims to understand the safety and tolerability of sacituzumab tirumotecan and measure how many participants respond to the treatment by having their cancer shrink or disappear. Participants may receive sacituzumab tirumotecan by intravenous infusion alone or with other anticancer drugs such as fluorouracil (5-FU), leucovorin or levoleucovorin, cisplatin, and pembrolizumab. Rescue medications like diphenhydramine, H2 receptor antagonists, acetaminophen, dexamethasone, and a steroid mouthwash are given to prevent infusion reactions and oral side effects. Supportive care treatments for side effects, including antidiarrheal and antiemetic agents, are allowed throughout the study. During the study, researchers monitor participants for dose-limiting toxicities within about 4 weeks and track adverse events, treatment discontinuations, and tumor response over up to approximately 63 months. Assessments include safety evaluations and measuring cancer response using standardized criteria. This long-term follow-up helps evaluate both the effectiveness and safety of the treatments being studied.

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 looking for ways to treat germinal center B-cell-like diffuse large B-cell lymphoma (GCB DLBCL). DLBCL is a fast-growing blood cancer that affects B-cells. GCB is a type of DLBCL that affects young B-cells that are still maturing. The goal of this study is to learn if more people who receive zilovertamab vedotin (MK-2140) and R-CHP have the cancer respond (go away) than those who receive polatuzumab vedotin and R-CHP.

Researchers are evaluating the safety and effectiveness of ETX101, a gene therapy, in infants and children diagnosed with SCN1A-positive Dravet syndrome. This is a Phase 1/2, two-part, multicenter study including participants aged 6 months to under 36 months in Part 1A, 48 months to under 18 years in Part 1B, and 6 months to under 48 months in Part 2. Part 1A uses an open-label dose-escalation design, Part 1B is open-label, and Part 2 is a randomized, double-blind, sham delayed-treatment controlled study. ETX101 is a single dose gene therapy delivered through an intracerebroventricular injection. It uses a viral vector to increase the expression of the SCN1A gene, which is linked to Dravet syndrome. The study includes different age groups and designs to assess safety and response over varying durations and methods, including dose escalation and placebo control. Participants will be monitored for changes in seizure frequency from before treatment through up to one year after dosing, with assessments occurring between Week 5 and Week 52. The main outcome measure is the percentage change in monthly countable seizures. Safety and efficacy will be closely evaluated throughout the study, with follow-up visits to assess the participant’s condition and response to the gene therapy.

Researchers are evaluating a phase II, randomized, double-blind, placebo-controlled study involving 48 adults aged 18 to 70 years who have recently been diagnosed with acute HIV infection. The study aims to assess whether adding a combination of HIV-specific broadly neutralizing antibodies (bNAbs) to standard antiretroviral therapy (ART) is safe and whether this combination can delay the return of detectable HIV viral levels, reduce viral reservoirs, and improve HIV-specific immune responses compared to ART with placebo. Participants receive either the combination bNAbs or placebo along with ART at the start of the study. The bNAbs include VRC07-523LS given as a 10 mg/kg intravenous infusion over 15 to 30 minutes and PGT121.414.LS given as a 5 mg/kg intravenous infusion over 30 to 60 minutes, both administered once at entry. ART consists of daily oral tablets containing bictegravir, emtricitabine, and tenofovir alafenamide. The study includes multiple steps: initial treatment with ART and antibody or placebo infusions (Step 1), analytic treatment interruption (ATI) to monitor viral rebound (Step 2 and Step 3), and ART restart when criteria are met (Step 4). Throughout the study, participants undergo regular visits with laboratory tests to monitor HIV viral load, CD4+ T-cell counts, safety labs, and pregnancy tests when applicable. Researchers track the occurrence of significant adverse events related to the study antibodies and measure the time it takes for HIV viral levels to rebound after stopping ART. Participants must adhere to contraceptive requirements and use barrier methods to prevent HIV transmission during ATI. The total study duration includes treatment, interruption, and follow-up phases lasting up to 24 weeks or longer depending on individual progress.

Researchers are evaluating two school-based programs designed to help manage anxiety in autistic students aged 8 to 14 years. The study aims to compare Facing Your Fears - School Based (FYF-SB), a cognitive-behavioral therapy (CBT) program focused on anxiety reduction, with Zones of Regulation (ZOR), which uses CBT principles to improve emotion regulation through awareness and management of emotional states. This trial also examines the acceptability, feasibility, and satisfaction of these programs among students, caregivers, and school providers, particularly in schools serving historically underserved communities. Participants, including 200 autistic students with anxiety, their caregivers, and 150 interdisciplinary school providers (ISPs), will be involved. Schools in Colorado and North Carolina will be randomized to deliver either FYF-SB or ZOR. ISPs trained in one of the interventions will conduct small group sessions (2-5 students) over 12 weeks. Assessments will be conducted before and after the intervention, with follow-up evaluations six months later. Both programs incorporate CBT techniques but differ in approach: FYF-SB uses disorder-specific strategies and graded exposure to anxiety triggers, while ZOR teaches emotional state regulation through a metacognitive framework. Participants will undergo multiple assessments, including clinician-administered and parent- and child-reported anxiety scales, emotion dysregulation measures, and school-related functional outcomes such as attendance and disciplinary actions. Surveys and interviews will assess program acceptability and feasibility among all participant groups. Treatment fidelity will be monitored through checklists. The study's primary endpoint is the change in anxiety symptoms six months after intervention completion, with ongoing monitoring and statistical analysis to evaluate effectiveness and inform school program selection.
