A Pharmacokinetic Study of D-2570 in Participants With Hepatic Impairment and Normal Hepatic Function

July 15, 2026 updated by: InventisBio Co., Ltd
This is a single-center, non-randomized, open-label, parallel-group study. It will test D-2570 in people with liver problems and in people with healthy livers, to see how the drug moves through the body and whether it is safe.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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-center, non-randomized, open-label, parallel-controlled study designed to evaluate the pharmacokinetic profile and safety of D-2570 in participants with hepatic impairment and those with normal hepatic function. Participants with hepatic impairment will be enrolled first, followed by participants with normal hepatic function.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

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

Yes

Description

Inclusion Criteria:

  • Voluntarily participate in this study and sign the written informed consent form after full informed consent, and agree to comply with the procedures specified in the study protocol.
  • Aged 18 to 70 years.
  • Both males and females are eligible.
  • Male participants must weigh no less than 50 kg, and female participants must weigh no less than 45 kg.
  • Participants with normal hepatic function must have adequate hematologic, renal, and hepatic function.
  • Have no plan to reproduce or donate sperm/eggs from screening until 30 days after the last dose of study drug, and agree to either completely abstain from sexual intercourse or use effective contraceptive measures from screening until 30 days after the last dose of study drug, as detailed in Appendix 3.

Exclusion Criteria:

  • Have undergone any prior surgery that may affect drug absorption, distribution, metabolism, or excretion, which, in the opinion of the investigator, would make the participant unsuitable for enrollment.
  • Are female and currently lactating, or have a positive serum pregnancy test result at screening or during the study period.
  • Have a known history of drug or substance abuse, or test positive for drugs of abuse on the urine drug screen.
  • Have participated in another interventional clinical trial within 3 months prior to screening, or are currently participating in another clinical trial (participants who withdraw from a prior trial before treatment, i.e., were not randomized or did not receive study intervention, may be enrolled in this study).
  • Have received a live vaccine within 2 months prior to study drug administration, or intend to receive a live vaccine during the study period.
  • Have any other condition or finding that, in the opinion of the investigator, would make the participant unsuitable for participation in this study.
