Researchers are evaluating remibrutinib (LOU064) in adolescents aged 12 to under 18 years who have chronic spontaneous urticaria (CSU) that is not well controlled by H1-antihistamines. This Phase 3 trial aims to assess the effectiveness, how the drug is processed in the body, and safety of remibrutinib compared to a placebo. The study also intends to gather long-term data on how well remibrutinib works and its safety over several years after treatment ends. The trial includes three periods. First, the core period is a 24-week double-blind phase where about two-thirds of participants receive remibrutinib and one-third receive placebo, with about 10 site visits over approximately 32 weeks. Next is an optional open-label extension lasting from one to three years, where participants who completed the core period may receive remibrutinib or enter an observational treatment-free phase depending on their symptoms. Participants may cycle through treatment and observational periods up to six times. Finally, an optional long-term treatment-free follow-up can last up to three years with one site visit and up to four phone calls. During the study, participants undergo assessments including changes in urticaria activity scores (UAS7), itching severity (ISS7), and hive severity (HSS7) measured from baseline to 12 weeks. Regular visits monitor safety, symptoms, and drug effects. The study tracks these measures to understand remibrutinib's impact on CSU symptoms and overall safety profile during and after treatment, with total participation potentially lasting several years.

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 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.

This study is a multicenter, open-label, phase I/II study of YL205 in China to evaluate the safety, tolerability, PK characteristics and preliminary efficacy of YL205 in the following selected patients with advanced solid tumors.

Researchers are evaluating the experimental antibody COM701 in participants with relapsed platinum sensitive ovarian cancer (PSOC). This trial aims to find out if COM701, given as a maintenance treatment, can delay the progression of ovarian cancer, delay the need for new anti-cancer treatments, and to assess its safety. The study is part of an adaptive-platform trial with multiple sub-studies, focusing initially on COM701 alone compared to a placebo. Participants are randomly assigned in a 1:2 ratio to receive either a placebo or COM701 via intravenous infusion every 3 weeks. The trial includes a double-blind, randomized, placebo-controlled design for the first sub-study. Future sub-studies will explore COM701 combined with other anti-cancer drugs. During the study, participants will visit the clinic every three weeks for treatment and monitoring. Health checks include physical exams, vital signs, ECGs, blood and urine tests, and pregnancy tests if applicable. Disease response will be assessed with CT or MRI scans and tumor marker tests using tumor tissue samples. The primary measure is progression-free survival, tracking time from randomization until disease progression or death, assessed up to two years.

Researchers are developing a culturally tailored smartphone app called HealthyCells to help African American smokers quit smoking and reduce sedentary behavior. This project integrates two existing evidence-based interventions—PrevailGO, which provides financial rewards for smoking abstinence verified remotely, and SMARTpath, which monitors sedentary time and prompts activity. African Americans face lower smoking cessation rates compared to other groups, despite higher quit attempts, and the study aims to address this disparity by offering tailored content and support via smartphone technology. The study involves creating the HealthyCells app with culturally relevant messages, images, and videos for African American smokers. Initially, a small group of 15 smokers will test the app and provide feedback to refine its content. After this, 30 African American smokers interested in quitting will use the app during a planned quit attempt. Starting on their quit date, participants will receive twice-daily prompts to report smoking status remotely and can earn rewards for abstinence. The app will also send real-time messages encouraging users to stand and move during long periods of sitting (30 minutes or more). Participants can access tailored information and strategies anytime within the app to support quitting smoking and reducing sitting time. Participants will be monitored for smoking abstinence confirmed biochemically at 8 weeks after quitting, and their sedentary time will be measured using a research-grade accelerometer before and 8 weeks after quitting. The study collects feedback through interviews and tracks activity and smoking status via the app. The main outcomes are the rates of smoking cessation and changes in daily sedentary behavior, helping assess whether HealthyCells is feasible and beneficial for African American smokers. The total participation time includes initial app testing and an 8-week period after the quit attempt.

Researchers are evaluating a culturally-tailored, home-based physical activity program designed to improve physical fitness in Hispanic or Latino/Latina adolescent and young adult childhood cancer survivors. These survivors may face long-term effects such as weight gain, fatigue, and reduced fitness after cancer treatment, with Hispanic or Latino/Latina individuals potentially at higher risk. The study aims to increase moderate to vigorous physical activity (MVPA) through a mobile health and social media intervention. The study has two stages. Stage 1 involves developing the intervention using feedback from 20 Latinx survivors who speak either English or Spanish. Stage 2 is a randomized controlled trial comparing the intervention group with a control group that only uses a Fitbit tracker. The intervention group receives Fitbit trackers, weekly reminders, goal-setting sessions, social media peer support 2-3 times a week, badges, monthly Zoom meetings, and may choose a physical activity partner who also receives support. After 12 weeks, a 4-week maintenance phase continues these supports with less structure. The control group wears a Fitbit daily for 12 weeks without additional support. Participants wear Fitbit trackers daily, attend weekly sessions, post on social media, and complete interviews and questionnaires. Researchers measure changes in physical activity levels, sedentary time, quality of life, and cardiometabolic health indicators. Data is collected using Fitbit devices, interviews, and surveys, with follow-up over 12 weeks plus maintenance. Safety and acceptability of the intervention are also assessed throughout the study.

Researchers are investigating whether buntanetap/Posiphen can help treat early Alzheimer's disease in adults aged 55 to 85 years. This Phase 3 study aims to find out if buntanetap/Posiphen improves thinking abilities and daily functioning compared to a placebo. It also evaluates the safety of buntanetap/Posiphen by monitoring any medical issues that participants may experience during the trial. Participants will take either a 30 mg capsule of buntanetap/Posiphen or a placebo capsule by mouth once daily for 18 months. The study includes regular clinic visits at screening, enrollment, and months 1, 3, 6, 9, 12, 15, and 18. During some visits, participants will have brain MRI scans. The study uses a double-blind design, meaning neither participants nor researchers know who receives the active drug or placebo. Throughout the study, participants will complete tests and questionnaires to measure cognitive function and daily living activities, including the ADAS-Cog13 and ADCS-iADL scales. Phone calls before and after visits help track progress and adherence. Safety is closely monitored with ongoing assessments from screening through the 18-month treatment period.

Researchers are evaluating the safety, tolerability, and preliminary anti-tumor activity of AO-252, an oral drug that inhibits the protein-protein interaction of TACC3, in adults with advanced solid tumors, including those with brain metastases. This Phase 1 study aims to determine the maximum tolerated dose and recommended dose for future studies, focusing on patients whose tumors have specific genetic mutations or features and who have previously received treatment. Participants will receive AO-252 as daily oral tablets or capsules during a dose-escalation and dose-expansion study. The trial includes patients with metastatic or locally advanced solid tumors that are unresectable and have certain genetic mutations or characteristics, including prostate cancer with specific criteria and solid tumors with brain metastases. The study allows previously treated brain metastases under defined conditions and evaluates response using established cancer response criteria. Participants will undergo safety assessments for up to 30 months during the dose-escalation and expansion phases. Researchers will monitor treatment tolerability, pharmacokinetics, and pharmacodynamics, along with anti-tumor effects. Regular evaluations include blood tests, imaging scans, and clinical assessments to track disease progression and side effects. Patients must be able to provide consent and meet other health criteria to ensure safety throughout the study period.

Researchers are evaluating the safety and effectiveness of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) whose disease has not worsened after definitive platinum-based concurrent chemoradiation therapy. This Phase III, randomized, double-blind, placebo-controlled, international study involves multiple centers. Participants receive intravenous infusions of durvalumab and domvanalimab or durvalumab and placebo. The treatments are given after patients have completed concurrent platinum-based chemotherapy and radiation therapy with a total radiation dose of approximately 60 Gy. The study monitors patients over time to assess treatment effects and safety. During the study, participants undergo evaluations including tumor tissue analysis for PD-L1 status, performance status assessments, and monitoring of organ and marrow function. The main outcome measured is progression-free survival up to 8 years after randomization. Researchers also monitor for any adverse effects and disease progression throughout the study period.
