Study Overview

Status

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.

Detailed Description

The objective of this study is to evaluate the PK, safety and tolerability of orally administered single-dose HRS-5041 in healthy Caucasian male participants.

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.
Interventional

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 aged between 18 to 55 years of age (inclusive) at the date of signed consent form.
  4. Total body weight ≥ 50.0 kg, body mass index (BMI) between 19.0 and 32.0 kg/m2 (inclusive) at screening.

Exclusion Criteria:

  1. History of receiving any androgen receptor (AR) degraders.
  2. History or evidence of clinically significant
  3. History of severe abnormal gastric emptying, severe gastrointestinal (GI) disease, or participants who had GI surgeries (except GI polypectomy).
  4. Severe infections, injuries, or major surgeries as determined by the investigator within 6 months
  5. Any other circumstances (e.g., not suitable for venous access) or laboratory 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
