About this study

Official title: Single and Multiple Dose -Based Tolerability, Safety and Pharmacokinetic Phase 1 Study of Humanized Anti-CD6 Monoclonal Antibody Injection in Chinese Patients With Psoriasis

The humanized recombinant anti-CD6 monoclonal antibody Injection (T1h) has been approved for psoriasis in India. The first trial in China is to evaluate the tolerability, safety, pharmacodynamic, pharmacokinetics and preliminary efficacy of T1h for patients with psoriasis.

Read the detailed description

The humanized recombinant anti-CD6 monoclonal antibody (T1h) is developed whose ligand binding properties of the original murine monoclonal antibody are preserved on the CD6 molecule. T1h monoclonal antibody has been approved for clinical studies of autoimmune diseases in Cuba and India, such as psoriasis and rheumatoid arthritis (RA).

Single and multiple dose based tolerability, safety and pharmacokinetic phase 1 Study of Humanized Anti-CD6 Monoclonal Antibody Injection in Chinese patients with psoriasis, 40 patients are enrolled. They are divided into 4 groups (0.2mg/kg, 0.4mg/kg, 0.8mg/kg, 1.6mg/kg) and each group includes 10 patients. First, these doses are all single-dose administration gradually from low then the doses 0.4mg/kg, 0.8mg/kg and 1.6mg/kg are multi-dose administration gradually from low.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing T1h in people with Psoriasis, run by Biotech Pharmaceutical 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 14 inclusion and 16 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: stopped early, as of the sponsor's last update on 27 Apr 2023. 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 was stopped early (reason given: company strategy). Results are not available in the source record.

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?

Adverse events (time frame: from patients with informed consents to 30 days after the last administration). 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 27 Apr 2023.
