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 studying 89Zr-TLX250, a diagnostic imaging agent, to detect clear cell renal cell carcinoma ccRCC in Chinese patients with indeterminate renal masses. This Phase 3, open-label, single-arm study aims to confirm the safety, tolerability, sensitivity, and specificity of 89Zr-TLX250 PETCT imaging. The study supports prior ZIRCON trial data and involves adult patients scheduled for partial or total nephrectomy as part of their standard care. Participants will receive a single intravenous dose of 37 MBq of 89Zr-TLX250 containing 10 mg of girentuximab. Imaging of the abdomen using PETCT will be performed 5 days post-administration, with possible whole-body imaging if widespread disease is suspected. Nephrectomy will occur any time after imaging but within 90 days. Histological analysis of tumor samples will confirm diagnosis. The study includes approximately seven visits over 4 to 6 months. Assessments include baseline exams, PETCT imaging, surgery, and follow-up visits. Imaging and histological data will be centrally analyzed to evaluate diagnostic accuracy. Safety and tolerability will be monitored throughout. The study is expected to last about 12 months with 4 months of follow-up per participant.

Researchers are evaluating TQB2934, a special antibody designed to target multiple myeloma, a cancer affecting plasma cells. This antibody binds to T cells and cancer cells to activate the immune system to attack the disease. The study is a Phase 1 clinical trial focusing on safety and the bodys handling of the drug in patients with malignant plasma cell tumors. The study involves giving TQB2934 as a subcutaneous injection at doses of 40mg or 60mg. Treatment cycles occur once weekly during the first three cycles, then every two weeks for cycles four to six. If patients achieve a partial remission or better after six cycles, dosing continues every four weeks. Each treatment cycle lasts 28 days. Participants will undergo various assessments including blood tests to measure drug levels and immune response over 120 hours after each dose. Researchers will monitor adverse events for up to 24 months and evaluate treatment responses such as remission rates and survival outcomes. The total study participation includes treatment and long-term safety follow-up lasting up to two years.

Researchers are studying relapsed or refractory multiple myeloma in adults who have already received treatment with lenalidomide and a proteasome inhibitor but whose disease has progressed. The study aims to evaluate the effects of adding SG301 injection to the standard treatment of pomalidomide and dexamethasone. This is a randomized, placebo-controlled, double-blind, multicenter phase III clinical trial. The study has two stages. Stage 1 is to find the right dose of SG301 combined with pomalidomide and dexamethasone. Stage 2 randomly assigns participants to receive either SG301 injection plus pomalidomide and dexamethasone or a placebo plus the same drugs. SG301 and its placebo are given by intravenous infusion weekly for 8 weeks, then every 2 weeks. Pomalidomide capsules are taken orally once daily on days 1 to 21 of each 28-day cycle. Dexamethasone is taken orally or by infusion on days 1, 8, 15, and 22, with dose adjusted for low body weight. Participants continue treatment until their disease progresses, unacceptable side effects occur, or other stopping criteria are met. Researchers will monitor side effects, drug levels in the body, immune response, and treatment effects including progression-free survival and overall survival for up to about 4 years. The study includes regular assessments every 4 weeks initially, then every 8 weeks, with safety followed for about 30 days after treatment ends.

Researchers are studying a treatment for elderly patients aged 65 and older with advanced triple-positive breast cancer. This cancer type is characterized by tumors that test positive for HER2, estrogen receptor, and progesterone receptor. The study aims to confirm the safety and effectiveness of a new combination therapy including Darcilide, pyrrotinib, and aromatase inhibitors letrozole, anastrozole, or exemestane for these patients who often have low physical status and poor tolerance for toxic chemotherapy. Participants will receive a combination treatment of Darcilide taken orally at 125 mg once daily for 21 days followed by 7 days off in 28-day cycles. They will also take an aromatase inhibitor daily and pyrrotinib starting at 240 mg orally once daily, with the dose potentially increasing to 320 mg if side effects are manageable. Treatment continues until disease progression, intolerable side effects, withdrawal of consent, or investigator decision. The study includes a screening period up to 28 days, followed by treatment and regular imaging assessments based on clinical routine and RECIST 1.1 criteria. During the study, participants will have safety checks, imaging evaluations, and follow-up visits including one 28 days after the last treatment. Safety follow-up continues until adverse events resolve or death. Efficacy follow-up continues until tumor progression, death, or consent withdrawal. Survival follow-up lasts until death, withdrawal, or the studys end date. Researchers will measure progression-free survival as the primary outcome over 29 months, along with overall survival, response rates, disease control, and duration of remission.

Researchers are conducting a Phase 1, open-label, multicenter clinical study to evaluate the safety, pharmacokinetics, and preliminary efficacy of HMPL-506 in patients with hematological malignancies. The study focuses on patients with specific genetic alterations in blood cancers, including relapsed or refractory Acute Myeloid Leukemia AML, Acute Lymphocytic Leukemia ALL, and multiple myeloma MM. The trial is sponsored by Hutchmed and aims to enroll between 60 and 132 patients across two phases dose escalation and dose expansion. In the dose escalation phase, approximately 30 to 38 patients with MLL-rearranged andor NPM1-mutant relapsedrefractory AML or ALL will receive escalating oral doses of HMPL-506 once daily. Starting at 50 mg, doses may increase based on safety, efficacy, and pharmacokinetic data, with adjustments guided by a Safety Monitoring Committee. The dose expansion phase will enroll about 30 to 60 patients divided into three cohorts based on specific genetic markers or disease type. Patients in this phase will receive the recommended phase 2 dose in 28-day cycles until disease progression, unacceptable toxicity, or other study endpoints. Participants will undergo regular assessments including bone marrow aspiration and biopsy, safety monitoring for dose-limiting toxicities and adverse events, and evaluations of anti-tumor efficacy every treatment cycle. Pharmacokinetic and pharmacodynamic analyses will be conducted, along with electrocardiograms and laboratory tests. Safety follow-up will continue up to 42 months after the last dose. The study includes monitoring for serious adverse events and overall survival, with participants remaining under medical supervision throughout the trial duration.
