About this study

Official title: A Randomised, Double Blind, Placebo Controlled, Single Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of SHR-1703 Injection Administered Subcutaneously in Healthy Subjects

SHR-1703 is a monoclonal antibody under development for severe asthma. This study is the first study in Healthy subjects. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of a single dose SHR-1703 administered subcutaneously in Chinese healthy subjects.

Read the detailed description

This study will be conducted at 1 study center in China. Approximately 42 healthy Chinese male and female subjects, aged 18 to 55 inclusive, will be randomized to receive a single SC administration of SHR-1703: Treatment 1, Treatment 2, Treatment 3, Treatment 4 and Treatment 5. Each subject will participate in only 1 treatment group. The total length of the study for each subject is up to 190 days (28 days of screening and 155+/- 7 days of further study visits).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SHR-1703 in people with Asthma, run by Jiangsu HengRui Medicine 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 8 inclusion and 10 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 14 Nov 2022. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Number of participants with Adverse events (AEs) and serious adverse events (SAEs) (time frame: From Day 1 to Days 155). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04480762, which also lists 1 linked publication.

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 14 Nov 2022.
