A Randomized, Double-Blind, Placebo-Controlled, Dose Escalation Phase I Clinical Study to Evaluate Safety and Pharmacokinetics of HLX70 in Healthy Adult Volunteers
Read the detailed description
A randomized, double-blind, single-dose by intravenous administration, placebo-controlled, dose escalation, first-in-human study is proposed to evaluate the safety, PK, and immunogenicity of HLX70 in healthy subjects. The investigators plan to enroll 8 subjects in each of the 3 dose cohorts at 3 mg/kg, 10 mg/kg, and 30 mg/kg, of which 2 receive intravenous injections of placebo and 6 receive intravenous injections of the investigational product (IP). A total of 24 subjects will be enrolled.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing HLX70 in people with COVID 19, run by Hengenix Biotech Inc.
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 5 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The record says: withdrawn, as of the sponsor's last update on 1 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
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The study was withdrawn before enrolling participants, so there are no results.
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, serious adverse event and infusion-related reactions as assessed by CTCAE v5.0 (time frame: up to 92 days). The study lists 2 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 NCT04561076, 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 1 Apr 2022.
