Filter by:Phase III, open-labeled, randomized and multicenter clinical trial to evaluate the superiority of romiplostim plus dexamethasone vs dexamethasone alone in patients with newly diagnosed primary immune thrombocytopenia
The study is designed to characterize the safety and tolerability of VLX-1005 and argatroban administered intravenously, either alone or in combination; and the pharmacokinetics and pharmacodynamics and potential interaction of both agents in a population of healthy subjects.
Elderly ITP patients have many underlying diseases, hormone contraindications and many adverse reactions during the use of hormones. TPO-RAs are oral small-molecule non-peptide drugs. Retrospective studies have shown that they have good efficacy and high safety in elderly patients. Therefore, this study is a prospective trial to evaluate TPO-RAs as the first-choice drug for the treatment of elderly ITP patients with contraindications to hormones, aiming to improve the efficacy-risk ratio of elderly patients
A phase 2, open-label, single-arm study to evaluate the efficacy and safety of iguratimod for the treatment of adults with steroid-resistant/relapse immune thrombocytopenia (ITP)
Randomized, open-label, multicenter study to compare the efficacy and safety of combination of iguratimod and danazol versus danazol for the treatment of adults with steroid-resistant/ relapse immune thrombocytopenia (ITP).
This project was undertaken to evaluate the efficacy and safety of BTK inhibitor Zanubrutinib for the secondary treatment of adults with primary immune thrombocytopenia (ITP).
The study is aimed to evaluate the efficacy of different doses of hetrombopag compared to placebo, measured by the proportion of subjects that can complete two planned consecutive chemotherapy cycles with no modification of chemotherapy regimen (i.e., delayed start, dose reduction, omission, or discontinuation) because of thrombocytopenia [platelet count <100×109/L], to determine an optimal dose of hetrombopag and to demonstrate its superiority over placebo.
Patients with cancer are prone to have blood clots, which are usually treated with blood thinners. The main complication of blood thinners is bleeding. This is especially a concern when the number of platelets in the blood is lower than 50,000 per microliter. The role of platelets is to stop bleeding, so when the number of platelets is low, patients are at a higher risk of bleeding. Cancer patients are prone to have lower platelet numbers due to cancer therapies and/or cancer itself. It is not clear what the best treatment is for cancer patients who need blood thinners for a blood clot but have low platelet counts. The investigators plan to do a small study called a pilot study to help plan for a larger study in such patients. In the pilot study, investigators will include 50 patients with cancer, low platelet counts, and a blood clot diagnosed within 4 weeks. Patients will be randomly assigned to one of the two treatment strategies: the full dose of blood thinners along with platelet transfusion or a reduced dose of blood thinners without platelet transfusion. The investigators will follow all patients for 90 days. If this pilot study is successful, it will help lead to a much larger trial, which will provide important information on the best treatment strategy in these patients.
Background/Rationale: A very rare syndrome of thrombosis associated with low platelets has been reported in a few cases of recent exposure to COVID-19 vaccine. This thrombotic thrombocytopenia syndrome seems to be affecting patients of all ages and both genders; at present there is no clear signal of risk factors. Objectives: To evaluate an association between COVID-19 vaccine exposure and thromboembolic events occurring with thrombocytopenia (thrombotic thrombocytopenia syndrome; TTS). Study design: Two primary study designs will be considered, a case control study and a self-controlled case series (SCCS). A cohort analysis will be considered, in addition or as an alternative to either of the primary study designs, pending feasibility assessment of the follow-up time. Data Source(s): Data for the study will be accessed through the NHS Digital Trusted Research Environment (TRE), providing national data coverage. Primary care data will be linked with vaccination, hospitalization, COVID-19 test results, mortality data. Initial exploratory analyses will be conducted using the Oxford-Royal College of General Practitioners sentinel network; ORCHID network database (N>15million). Subjects of interest are patients who have received a COVID-19 vaccine. However, investigators will require access to data from all subjects in the databases. Statistical Analysis: The study period will start on December 02, 2020, when the COVID-19 vaccine was first approved in the UK and will end at the end of data availability. For the case-control design, all cases of TTS will be matched with control using risk-set matching. A case or matched control will be considered exposed if a COVID-19 vaccination will be within risk interval prior to the diagnosis date of the matched case. For the SCCS, estimates of relative incidence (RI), in all risk intervals will be reported. For the retrospective cohort design, the incidence of TTS after receiving COVID-19 vaccine will be estimated and investigators will compare this incidence with that occurring in an unvaccinated comparator group about levels of infection across the whole population. Variables: Demographic, socioeconomic descriptors, clinical diagnosis, vaccines, potential confounders, thrombotic phenomena, COVID-19 infection, and other characteristics as applicable.
The purpose of this study is to explore the safety and efficacy of herombopag olamine tablets for thrombocytopenia induced by chemotherapy combined with immunotherapy in non-small cell lung cancer
