About this study

Official title: A RANDOMIZED, DOUBLE-BLIND, INTRAVENOUS SINGLE-DOSE, PARALLEL-CONTROLLED PHASE I CLINICAL STUDY TO COMPARE THE PHARMACOKINETICS, SAFETY, AND IMMUNOGENICITY OF PERTUZUMAB INJECTION BEFORE AND AFTER PROCESS CHANGE IN HEALTHY MALE PARTICIPANTS

This is a randomized, double-blind, parallel-controlled study to compare the PK profile of HLX29 and HLX11 and evaluate their safety, tolerability, and immunogenicity after a single intravenous dose in healthy male adult participants.

Being tested
HLX29, HLX11

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. AUC0-inf

    Area-under-curve of blood drug concentration-time from time 0 to infinity after a single drug administration

    Measured: up to 71 days

Secondary outcomes (2)
  1. Cmax

    Peak concentration after a single administration

    Measured: up to 71 days

  2. AUC0-t

    Area under the serum concentration-time curve from time 0 to the time of the last quantifiable concentration

    Measured: up to 71 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HLX29 and HLX11 in people with Health Adult Subjects, run by Shanghai Henlius Biotech at 1 site in Australia.

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 8 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: opening soon, as of the sponsor's last update on 21 Oct 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 Australia. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Iren Cheng (65-97503712, irene_cheng@henlius.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

AUC0-inf (time frame: up to 71 days). 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 21 Oct 2026.
