Summary: The purpose of this study is to compare the efficacy of two study drugs, Avatrobopag versus placebo, to treat persistent Chemotherapy-Induced Thrombocytopenia (CIT) in patients with gastrointestinal (GI) malignancies receiving cytotoxic chemotherapy. The names of the study drugs involved in this study are: * Avatrombopag (a thrombopoietin receptor agonist) * Matching placebo

Summary: This is a single-center, open label pilot trial where patients with primary ITP who require second line treatment will be offered avatrombopag at a reduced starting dose, adjusted thereafter according to the response and continued for up to 24 weeks. The study aims to acquire experience on use of avatrombopag and explore the efficacy and safety of lower starting dose of avatrombopag

Summary: This prospective, open-label, single-center, one-arm clinical trial aims at evaluating the efficacy and safety of avatrombopag in Chinese adult Immune Thrombocytopenia (ITP) patients with autoantibodies fail (due to intolerance or resistance) to eltrombopag or herombopag treatment.

Summary: To evaluate the efficacy and safety of Avatrombopag to treat chemotherapy-induced thrombocytopenia in solid tumors

Summary: To evaluate the safety and efficacy of avatrombopag in the treatment of pediatric primary immune thrombocytopenia in patients who have been treated with eltrombopag before and switched to avatrobopag because of poor efficacy, excessive platelet fluctuation or intolerance, or patient preference, economic reasons, and other reasons.

Summary: To evaluate the efficacy and safety of Avatrombopag for platelet recovery after unrelated cord blood transplantation (UCBT) in patients with bone marrow failure disease

Summary: In this study, investigators aim to evaluate the efficacy of avatrombopag in thrombocytopenic patients after haploidentical hematopoietic stem cell transplantation (haplo-HSCT) through a prospective, multi-center, double-blinded, randomized placebo-controlled clinical trial.

Summary: This multicenter randomized, open-label study aim to compare the efficacy and safety of TPO-RAs combining anti-CD 20 monoclonal antibody with TPO-RAs in China pediatric ITP patients .This study will be conducted in persistent or chronic pediatric ITP patients who had not responded to or had relapsed after previous glucocorticoid treatment.

Summary: This prospective, open-label, nonrandomized, multicenter clinical trial aims at comparing the efficacy and safety of combined use of TPO-RAs with low-dose anti-CD20 monoclonal antibody vs. the best available therapy（BAT）in adult immune thrombocytopenia with autoantibodies failed (due to intolerance or resistance) to first-line treatment.

Summary: For elderly patients who cannot tolerate anti-thymocyte globulin (ATG) treatment, the addition of avatrombopag (AVA), which has a slight adverse reaction, can theoretically improve the hematological response rate in elderly patients with non-severe aplastic anemia (NSAA) without significantly increasing adverse reactions. Based on this, this study treated NSAA patients older than 60 with AVA combi...

Summary: This study was a single-arm, multicenter, phase Π clinical study. Patients admitted to the enrollment unit center with a confirmed diagnosis of TDNSAA/VSAA/SAA, treated with IST (p/r-ATG+CSA) in combination with TPO-RA (including eltrombopta or hydtrombopta) for at least 3 months with no hematologic response at 6-month follow-up, and who were not suitable or unwilling to undergo hematopoietic stem...
