Researchers are evaluating how well elritercept works to improve anemia in adults with myelofibrosis MF who are already taking ruxolitinib. The study compares elritercept to a placebo and aims to see if elritercept can reduce tiredness, improve MF-related symptoms, and help participants perform physical activities more easily. It also looks at elritercepts effects on bone marrow, spleen size, antibody development, and long-term safety. Participants receive either elritercept or a placebo by subcutaneous injection once every 4 weeks during a 36-week double-blinded treatment period. The starting dose of elritercept is 3.75 mgkg, with a possible increase to 5.0 mgkg after the second cycle based on response and safety. After 36 weeks, participants who took placebo may switch to receive elritercept in an extended open-label phase. During the study, participants undergo assessments including blood transfusion independence, symptom and fatigue questionnaires, spleen imaging, and bone marrow evaluation. Researchers monitor safety, antibody formation, and survival for up to 7 years. The main outcome is the proportion of participants who become independent from red blood cell transfusions for at least 12 consecutive weeks during the 36-week treatment. Participants are involved in regular visits and evaluations throughout the treatment and follow-up periods.

This research aims to evaluate the long-term safety of luspatercept in participants who have previously taken part in other luspatercept clinical trials for conditions such as Myelodysplastic Syndromes MDS, Beta-thalassemia, and Myeloproliferative Neoplasm-associated Myelofibrosis. It is a Phase 3b, open-label, single-arm rollover study designed to continue monitoring participants who tolerated previous luspatercept treatment and may benefit from ongoing therapy, as well as those in post-treatment follow-up phases. Participants transitioning from prior luspatercept studies will enter a Transition Phase defined by an enrollment visit. Those continuing treatment will receive luspatercept injections subcutaneously at the same dose and schedule as their parent trial, administered by study staff at clinical sites. The study includes a Treatment Phase for ongoing luspatercept administration and a Follow-up Phase comprising a 42-day safety follow-up after the last dose and a long-term post-treatment follow-up phase lasting at least 5 years to monitor overall survival and progression to malignancies. Throughout the study, participants will be regularly assessed for adverse events, progression to high-risk MDS or AML, and development of other malignancies or treatment-related masses. Safety parameters are evaluated during the 42-day follow-up, while long-term survival and disease progression are monitored every six months for at least five years. The study will conclude when all participants have completed five years of combined treatment and follow-up.

Researchers are evaluating the efficacy and safety of tulisokibart in participants with moderately to severely active Crohns disease. This program includes two studies Study 1 involves both induction and maintenance treatment phases, while Study 2 focuses only on induction treatment. The main goal is to determine if one or more doses of tulisokibart are more effective than placebo in achieving clinical remission and endoscopic response at various time points up to Week 52. Participants are randomly assigned to receive different dosing regimens of tulisokibart or placebo. These regimens include high or low doses administered intravenously followed by subcutaneous injections, or subcutaneous injections alone. Some participants may continue in an extension phase receiving subcutaneous doses after completing their original treatment arm if they meet specific requirements. The studies use a double-blind design to compare tulisokibarts effects against placebo. During the trial, participants undergo regular assessments to measure clinical remission, endoscopic response, and other health outcomes using tools like the Crohns Disease Activity Index and stool frequency with abdominal pain scores. Safety evaluations include monitoring adverse events and treatment discontinuations. The studies last up to 52 weeks for Study 1 and 12 weeks for Study 2, with multiple visits to assess treatment effects and participant health under medical supervision.

Researchers are evaluating tozorakimab as an additional treatment to standard care in adults hospitalized with viral lung infection who need supplemental oxygen. The study aims to determine if tozorakimab can help prevent death or the need for invasive mechanical ventilation or extracorporeal membrane oxygenation. This Phase III trial involves a large group of participants to assess the safety and effectiveness of this approach. Participants are randomly assigned to one of two groups one group receives a single intravenous dose of tozorakimab on the first day, while the other group receives a matching placebo. The study uses a double-blind design, meaning neither participants nor researchers know which treatment is given. This helps ensure unbiased results. The treatments are given once, and participants continue to receive standard care during the trial. During the study, participants are closely monitored and evaluated up to 60 days after treatment. Researchers track important outcomes such as death rates, progression to invasive ventilation, days alive outside intensive care, and oxygen use. They also assess clinical progression using a World Health Organization scale and monitor for any anti-drug antibodies. The trial lasts until November 2027, with multiple assessments throughout to understand the treatments impact and safety.

This research investigates the effects of hypothermia versus normothermia on patients who have undergone extracorporeal cardiopulmonary resuscitation ECPR following out-of-hospital cardiac arrest OHCA. The trial aims to compare mortality risks, neurological outcomes, and adverse events between these two temperature management strategies. The study addresses uncertainties regarding the best temperature control after ECPR, which is a resuscitation method using ECMO to support heart and lung function during cardiac arrest. Participants receive either hypothermia treatment, where their body temperature is cooled to 33-34C using ECMO with a heat exchanger, or normothermia treatment, where the temperature is maintained at 36C. After reaching the target temperature, it is maintained for 24 hours, followed by a 24-hour rewarming period to 36-37.5C, which is then sustained until ECMO ends or for 24 hours post-rewarming. Additional treatments like sedation, muscle relaxants, antipyretics, and circulatory support may be used as needed. During the trial, participants are closely monitored for survival at discharge about 25 days, neurological function using cerebral performance categories, and adverse events during their intensive care stay approximately two weeks. Follow-up assessments occur at 30 days, 90 days, and one year after admission. The study tracks these outcomes to evaluate which temperature management approach might better support recovery after ECPR in OHCA patients.

Researchers are studying the safety and effectiveness of TARA-002, a biological preparation containing Streptococcus pyogenes cells, for adults aged 18 and older with high-grade non-muscle invasive bladder cancer NMIBC, including carcinoma in situ CIS with or without TaT1 tumors. This Phase 2 open-label trial further evaluates TARA-002 at a dose established in an earlier Phase 1a study. Participants include those with active disease confirmed within 3 months before enrollment, divided into two groups based on prior treatment with BCG therapy. Participants receive TARA-002 directly into the bladder through instillation. The treatment involves an initial period of six weekly doses, followed by a possible second period of six additional weekly doses or three weekly maintenance doses for those with a complete response. Maintenance doses continue at specified months up to 24 months. After treatment, participants enter a follow-up period lasting from month 27 to month 60 to monitor long-term outcomes. Throughout the study, participants undergo regular assessments including evaluations of tumor response, progression-free survival, overall survival, and quality of life using specific questionnaires. Researchers monitor urinary biomarkers and track adverse events from the first day of treatment through the entire follow-up period. The studys main outcome is the rate of high-grade complete response measured from 3 to 60 months after treatment. Total participation may last up to 5 years.

This trial evaluates nadofaragene firadenovec, a gene therapy using interferon alfa-2b amplification, compared with observation in participants with intermediate risk non-muscle invasive bladder cancer IR NMIBC. The study is a phase 3b, randomized, controlled trial aiming to assess treatment effects on recurrence-free survival over 24 months. Participants in the treatment group receive quarterly bladder instillations of nadofaragene firadenovec for 24 months. Disease evaluations occur within two weeks before each treatment instillation. Participants in both groups are followed according to the American Urological AssociationSociety of Urologic Oncology surveillance guidelines, which involve quarterly monitoring during the 24-month treatment period. During the study, participants undergo regular disease assessments, including monitoring for cancer recurrence and safety evaluations over 24 months. The main outcome measured is recurrence-free survival at 24 months. Adverse events and recurrence-free survival at 12 months are also tracked. Participants are monitored closely throughout the treatment and observation periods to evaluate long-term effects and safety.
