About this study
The overall design of this clinical study is a single center, randomized, open label, single dose, two sequence, two cycle bioequivalence trial in healthy individuals under fasting conditions. According to the randomized crossover self-control method, healthy volunteer subjects were orally administered with Eltrombopag Olamine Tablets produced by Chia Tai Tianqing Pharmaceutical Group Co., Ltd. and Reference Listed Drug (RLD) on an empty stomach to evaluate the human bioequivalence of single dose administration, providing reference for their clinical evaluation and medication.

Questions about this trial
What is this clinical trial studying?
A study testing Group 1: single-dose of test formulation+single-dose of reference formulation and Group 2: single-dose of reference formulation+single-dose of test formulation in people with Thrombocytopenia, run by Chia Tai Tianqing Pharmaceutical Group Co., Ltd. at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum Concentration (Cmax) (time frame: Before administration and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 12, 24, 48, 72 hours after administration). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jan 2025; AzTrials last refreshed its copy on 26 Oct 2026.
