Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-arm, prospective clinical study to evaluate the efficacy and safety of herombopag in the treatment of elderly patients with ITP. The study will include 80 patients. Screening of patients will be 2 weeks after the longest period, to enter after the treatment period, accept the herombopag 5 mg, once daily, on an empty stomach, oral medication can be eating only 2 hours, and 24 weeks of treatment, and adjust the dosage according to the platelet count. If patients do not respond to treatment after 8 weeks, it is recommended to withdraw from the study and continue safety visits for 4 weeks. During treatment, the patient continues treatment until the investigator assesses the occurrence of intolerable toxicity, disease progression, withdrawal of informed consent, or other discontinuation criteria specified in the protocol (whichever occurs first). Follow-up treatment for patients who withdraw from treatment due to safety or ineffectiveness is determined by the investigator according to clinical practice. Safety assessment during treatment, including vital signs, physical examination, laboratory examination, etc.; Check your blood routine at least once a week. A 4-week safety visit was performed after the final treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers
