Phase 1 Study of HRS-9231 Safety and Pharmacokinetics in Healthy Caucasians

December 4, 2024 updated by: Atridia Pty Ltd.

A Phase 1, Randomized, Double-Blind, Placebo-Controlled Dose Escalation Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of HRS-9231 in Healthy Caucasian Participants

This is a phase 1, randomized, double-blind, placebo-controlled study. The objective of this study is to evaluate the safety, tolerability, and PK profile of HRS-9231 injection following a single dose in healthy Caucasian participants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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 (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Healthy Caucasian participants;
  2. Ability to understand the trial procedures and possible adverse events, voluntarily participate in the trial,
  3. Male or female aged between 18 to 45 years of age (inclusive) at the date of signed consent form.
  4. Women with body weight of ≥ 45.0 kg, men with body weight ≥ 50.0 kg, body mass Index (BMI) between 18.0 and 32.0 kg/m2

Exclusion Criteria:

  1. History or evidence of clinically significant disorders
  2. Individuals with a history of drug allergies, specific allergies
  3. Severe infections, injuries, or major surgeries as determined by the investigator within 3 months prior to dosing, or plan to do surgeries during the study.
  4. Any other circumstances (e.g., not suitable for venous access) or laboratory
  5. abnormality that, in the investigator's judgment, may increase the risk to the participant, or be associated with the participant's participation in and completion of the Study or could preclude the evaluation of the participant's response.

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply
