Chronic hepatitis B virus HBV infection is a major global health issue that can lead to serious liver problems such as cirrhosis, liver cancer, and death. This observational study aims to gather detailed information from a broad group of Chinese patients with chronic HBV infection to better understand the factors that influence disease outcomes. The study involves creating a comprehensive database of clinical, epidemiological, biological, virological, immunologic, and treatment-related data from patients with chronic HBV infection. There are no drug interventions instead, participants are monitored as part of this long-term cohort. Participants will be followed over many years, with researchers tracking outcomes like loss of hepatitis B antigens, development of cirrhosis, liver failure, liver cancer, and mortality. Regular assessments will collect relevant health information to help identify the factors linked to disease progression. The study is planned to continue until 2030, providing extensive long-term data on chronic HBV infection.

Researchers are evaluating TQB3107, a targeted inhibitor designed to induce cell death and stop tumor growth, in patients with advanced cancers. This Phase I clinical trial aims to assess the safety and tolerability of TQB3107 tablets, determine dose-limiting toxicities, find the maximum tolerated dose, and recommend a dose for future Phase II studies. Participants receive TQB3107 tablets following one of two dosing schedules either daily for five consecutive days each week with a two-day break per 28-day cycle, or intermittent dosing every 28 days. The study begins with an initial single fasting dose followed by a seven-day observation before continuing the dosing cycles. This design allows researchers to monitor participants closely during the first cycle to assess safety and dosing effects. During the study, participants will have regular assessments including pharmacokinetic blood sampling at multiple time points to measure drug levels, and evaluations of dose-limiting toxicities and maximum tolerated dose at the end of the first 28-day cycle. Longer-term outcomes such as response rates, disease control, progression-free survival, and overall survival will be followed for up to three years. Participants are monitored for up to 24 months for recommended dosing and safety, with comprehensive evaluations throughout the study period.

Researchers are evaluating the effectiveness and safety of adding Orelabrutinib to a standard treatment of bendamustine plus rituximab in patients who have not previously been treated for mantle cell lymphoma MCL. This phase 3, randomized, double-blind study aims to compare the combination of Orelabrutinib with bendamustine and rituximab versus bendamustine and rituximab alone. The study is sponsored by InnoCare Pharma Inc. and focuses on patients with treatment-naive MCL, typically older adults. Participants will be randomly assigned to one of two groups one receiving Orelabrutinib orally along with bendamustine and rituximab injections, and the other receiving a placebo oral treatment with bendamustine and rituximab injections. Treatment will continue until the disease progresses or other reasons require stopping. The study uses a quadruple masking design, ensuring that participants and researchers do not know who is receiving Orelabrutinib or placebo. Throughout the study, participants will be monitored for dose-limiting toxicity within the first 28 days and followed for progression-free survival over approximately seven years. Researchers will conduct assessments to track disease status, side effects, and overall health. The trial involves regular visits, laboratory tests, and imaging to evaluate treatment effects and safety. Participants involvement may last several years, including long-term follow-up to understand treatment outcomes and risks.

Researchers are evaluating the long-term safety of subcutaneous guselkumab injections in children with moderately to severely active ulcerative colitis, Crohns disease, or juvenile psoriatic arthritis. This Phase 3 study focuses on pediatric participants who have previously been treated with guselkumab and will continue therapy in this extension study to monitor safety over an extended period. Participants who completed dosing in one of three primary pediatric guselkumab studies and are deemed by their investigator to benefit from continued treatment will join this long-term extension. Guselkumab is administered as a subcutaneous injection either every 8 weeks or every 4 weeks, depending on prior study assignment and clinical status. Some participants may switch dosing frequency once during the extension before unblinding, after which dosing aligns with their original regimen. Dose adjustments are restricted based on the primary study they came from. During the study, participants will receive guselkumab injections regularly and be monitored for treatment-emergent adverse events for up to nearly seven years. Researchers will assess safety outcomes through ongoing clinical evaluations over this time. Parents or legal representatives provide consent for children to participate, and children capable of understanding the study will give assent. The total participation duration may extend up to six years and nine months, allowing long-term safety data collection.

Researchers are investigating new treatments for adults with moderately to severely active ulcerative colitis or Crohns disease under a master protocol called Study IIBD. This Phase 2 trial evaluates multiple drugs to understand their safety and effectiveness in managing these conditions. Participants will be assigned to specific sub-studies and randomized to treatment groups, with the study lasting at least 62 weeks. The study includes two treatment periods. In the first period, participants may receive mirikizumab intravenously, or a combination of the oral drug LY4395089 with intravenous mirikizumab. Those who respond to treatment will then enter a second period where they receive mirikizumab through subcutaneous injections. These steps allow researchers to assess different dosing methods and combinations of these drugs. Participants will be monitored regularly throughout the study, including screening tests and laboratory evaluations to ensure eligibility and safety. Researchers will track the number of participants allocated to each treatment group up to day 42 as a primary outcome. The study involves randomization without masking and continues until at least 62 weeks, with ongoing assessments to evaluate treatment effects and monitor health outcomes.

This research aims to compare two oxygen concentration protocolsconstant 5% versus sequential 5%-2%used during embryo culture in assisted reproductive technology. The study focuses on women undergoing blastocyst transplantation to evaluate differences in term live birth rates and offspring health, including potential effects on telomere length, which is linked to aging and health outcomes. The trial is conducted across five centers, including the Clinical Center of Reproductive Medicine at the First Affiliated Hospital of Nanjing Medical University. Participants are randomly assigned to one of two groups one receives embryo culture under a constant 5% oxygen concentration, and the other under a sequential protocol reducing from 5% to 2%. Both groups follow their respective blastocyst culture protocols during in vitro fertilization or intracytoplasmic sperm injection cycles. The study monitors outcomes related to live births and health status of offspring associated with each oxygen protocol. Women enrolled in the trial will be followed for three years, during which live birth rates, clinical pregnancy rates, implantation rates, miscarriage rates, and ectopic pregnancy rates will be recorded. Researchers will also assess offspring health by measuring peripheral blood telomere length. Evaluations include monitoring pregnancy outcomes and any perinatal complications. Data will be statistically analyzed to determine the effects of oxygen concentration protocols on reproductive success and offspring well-being.

Researchers are evaluating the safety and tolerability of DB-1303BNT323 in adults with advanced or metastatic solid tumors that express HER2. This Phase 12a trial focuses on patients with tumors that are advanced, unresectable, recurrent, or metastatic and have limited or no standard treatment options. The study aims to identify the best dose and explore early signs of effectiveness in a variety of HER2-expressing cancers. The trial has two parts an initial dose-escalation phase using an accelerated titration followed by a classic 33 design to find the maximum tolerated dose MTD or recommended Phase 2 dose RP2D, and a dose-expansion phase to further assess safety, tolerability, and potential effects at the established dose. Participants receive DB-1303BNT323 by intravenous infusion once every three weeks Q3W at various dose levels. Some groups are randomized to receive different dose levels or combinations with other drugs like Pertuzumab, Ritonavir, or Itraconazole to study drug interactions and responses. During the study, participants will have regular assessments including monitoring for dose-limiting toxicities, adverse events, and serious adverse events using standard criteria up to about one year after treatment. Researchers will also evaluate tumor responses using RECIST 1.1 criteria and collect pharmacokinetic and pharmacodynamic data. Other evaluations include heart function tests, organ function, and overall health status. The study duration varies per participant, with follow-up visits extending up to one year post-treatment to monitor safety and treatment effects.

Researchers are evaluating the combination of baxdrostat and dapagliflozin in people with chronic kidney disease CKD and high blood pressure hypertension. This Phase III, double-blind, placebo-controlled study aims to assess whether this combination reduces the risk of serious kidney damage, heart failure events, or cardiovascular death compared to dapagliflozin alone. The study includes participants with CKD and hypertension who meet specific kidney function and blood pressure criteria. Participants who are not already taking SGLT2 inhibitors will first complete a 4-week dapagliflozin run-in period. Then, they will be randomly assigned to receive either baxdrostat plus dapagliflozin or a placebo plus dapagliflozin. Baxdrostat dosing may start low and be increased if needed. Study visits will occur at 2, 4, 8, 16, 34, and 52 weeks after randomization, and then approximately every four months until the study ends, which is based on the number of key kidney or heart-related events. Throughout the study, participants will have regular assessments including blood tests to monitor kidney function and potassium levels, blood pressure measurements, and evaluations of heart and kidney health. If participants stop the blinded study drug early, they will continue dapagliflozin if possible and remain in the study for ongoing visits and monitoring. The main outcome is whether the combination treatment reduces the risk of a 50% sustained decline in kidney function, kidney failure, heart failure events, or cardiovascular death over up to 37 months.

Researchers are evaluating the efficacy, safety, and tolerability of combining elecoglipron and dapagliflozin compared to each drug alone in adults with type 2 diabetes mellitus T2DM who have not achieved adequate control through lifestyle changes or other glucose-lowering medications. This Phase III study aims to better understand how these treatments work together in managing blood sugar levels in this population. Participants are randomly assigned to one of five groups two groups receive elecoglipron at different dose levels combined with dapagliflozin two groups receive elecoglipron at different dose levels combined with a placebo matching dapagliflozin and one group receives dapagliflozin alone with a placebo matching elecoglipron. All medications are taken orally once daily. The treatment period lasts 40 weeks, during which the effects of the drugs on blood sugar and other health measures will be monitored. Throughout the study, participants will have regular assessments of their blood sugar control, body weight, and blood pressure. Researchers will measure changes in Hemoglobin A1c HbA1c, fasting plasma glucose, and self-monitored blood glucose levels. Other outcomes include weight loss and the need for rescue medication. Safety and tolerability will be closely monitored. Participation in the trial lasts for 40 weeks, during which participants will attend scheduled visits for evaluation and medication monitoring.

Researchers are studying the effectiveness and safety of combining RC108 with Furmonertinib compared to Furmonertinib alone for treating patients with a specific type of advanced or recurrent non-small cell lung cancer NSCLC that has both EGFR mutations and MET positivity. This phase II clinical trial aims to better understand how these treatments work together for this condition. The trial involves two groups one receiving RC108 combined with Furmonertinib, and the other receiving Furmonertinib alone. Participants have unresectable locally advanced or recurrent metastatic NSCLC with certain EGFR mutations and MET positivity. Treatment and monitoring occur over several months, with careful evaluation of drug effects and safety. Participants will undergo tests for tumor response, survival rates, and disease control over a period of up to 45 months. Researchers will collect tissue samples, monitor side effects, and assess drug levels and immune responses. The study includes regular check-ins to measure how well the cancer responds and to track any adverse events or reactions.
