About this study

Official title: Double-blind, Placebo-controlled Phase I Clinical Study to Evaluate the Tolerability, Safety, Immunogenicity and Pharmacokinetic Profile of Single Dose of JS005 (Recombinant Humanized Monoclonal Antibody Against IL-17A) Injection in Healthy Volunteers

JS005-001 is one randomized, double-blind, placebo-controlled study to evaluate the tolerability, safety, immunogenicity and pharmacokinetic profile of single dose of JS005 injection in healthy volunteers.

A total of 5 dose groups are set in the study, i.e., 15 mg, 60 mg, 150 mg, 300 mg and 600 mg, single dose will be given subcutaneously in abdomen.

A total of 40 subjects are planned to be enrolled, 8 subjects will be enrolled in each group. Each dose group will be given the study drug and placebo at a ratio of 3:1. Each subject can only receive one single dose at one dose level.

Sentinel method will be used for dose escalation, and one independent safety evaluation team (SET) will be set up. 2 subjects (one receiving study drug, the other receiving placebo) will be randomized preferably and followed up until 3 days after administration when the dose starts in each dose group, the remaining 6 subjects (5 receiving study drug, 1 receiving placebo) can continue to be randomized after confirmation with the sponsor, if no any dose-limiting event (DLE) is observed during that period. Only when all the subjects at present dose level complete the follow-up for at least 14 days after administration, and no dose-limiting event (DLE) is observed in any one subject, the next dose level can be initiated after confirmation with the independent safety evaluation team and the sponsor, otherwise they must be observed for the full term of follow-up (i.e., on Day 85). If DLE is observed throughout the observational period, it is confirmed that ≤2/6 subjects have DLE after administration of the study drug through unblinding by the independent safety evaluation team, the next dose level can be initiated; if >2/6 subjects have DLE, the dose escalation will be terminated. The previous dose before that dose will be regarded as the maximum tolerated dose (MTD). When the dose for single dose is escalated to the preset maximum dose, and no safety endpoint is observed, it can be considered to continue to explore higher dose after joint decision by investigators and the sponsor.

  10. Percentage of Participants With Anti-JS005 Antibodies.

    Percentage of participants with treatment-emergent positive anti-JS005 antibodies was summarized by treatment group. Percentage was calculated based on the number of evaluable participants and was calculated by number of participants with treatment-emergent positive anti-JS005 antibodies / number of evaluable participants * 100%.

    Measured: From baseline through 24 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing JS005 (recombinant humanized monoclonal antibody against IL-17A) in people with Tolerability, Safety, Immunogenicity and Pharmacokinetic of JS005, run by Shanghai Junshi Bioscience 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 7 inclusion and 23 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 13 Aug 2026. 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. Some participants in this study may receive a placebo. 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 Clinically Significant Events . (time frame: From baseline through 12 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Aug 2026; AzTrials last refreshed its copy on 29 Oct 2026.
