Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase 3b open-label, multicenter study to evaluate the safety and efficacy of avatrombopag in subjects with thrombocytopenia scheduled for operations to critical sites or operations with a high risk of bleeding.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects will receive oral avatrombopag once daily for 5 days beginning on Day 1, followed by a wait period prior to the procedure, which will occur on Day 10 to 13. The Follow-up Period will include 2 visits; 7 days post-procedure and 30 days after last dose.

Inclusion Criteria

* Men and women greater than or equal to 18 years of age;
* A mean baseline platelet count between:

* 50 × 10\^9/L and \<100 × 10\^9/L for non-chronic liver disease participants
* 50 × 10\^9/L and \<75 × 10\^9/L for participants with chronic liver disease;
* Participant is scheduled to undergo operations to critical sites (eg, eye surgery, neurosurgery) or operations with a high risk of bleeding (eg, major abdominal surgery), or, in the opinion of the Investigator, would otherwise require a pre-operative platelet transfusion to prevent bleeding

Exclusion Criteria

* Participant with a history of arterial or venous thrombosis within 6 months of baseline;
* Participant with known portal vein blood flow velocity rate \<10 cm/second or previous portal vein thrombosis within 6 months of baseline;
* Participant plans to have a platelet transfusion or plans to receive blood products containing platelets within 7 days of the Baseline Visit;
