  • Participants treated with anti-HER2 therapy or any antibody or other protein drug targeting the HER2 receptor;
  • Participants who have taken any prescription or OTC drugs, including any herbal, and/or nutritional supplements (e.g. vitamins, mineral supplements or other health products) within 14 days before screening;
  • Use of any monoclonal antibody within 3 months or 5 half-lives (whichever is longer) before administration;

About this study

Official title: A Randomized, Double-Blind, Single-Dose, Parallel-Controlled Clinical Study to Compare the Pharmacokinetic Similarity Between QL1209 (Perjeta® Biosimilar Candidate) and Perjeta® (Pertuzumab) in Healthy Male Participants

The goal of this clinical trial is to evaluate the similarity of pharmacokinetic (PK) parameters following a single intravenous infusion of QL1209 (Perjeta® biosimilar candidate) and Perjeta® (Pertuzumab) in healthy male participants.

Participants will receive a single intravenous infusion of QL1209 or US-Perjeta® 420 mg on D1, followed by observation until Day 99 postdose for PK, safety and immunogenicity assessments.

Read the detailed description

This is a randomized, double-blind, single-dose, parallel-controlled clinical trial to compare the PK profile of QL1209 and Perjeta® in healthy male participants. It is planned to enroll 80 healthy male participants and randomize them into the test group or reference group at a ratio of 1:1.

Participants will receive a single intravenous infusion of QL1209 or US-Perjeta® 420 mg on Day 1, followed by observation until Day 99 post-dose for PK, safety and immunogenicity assessments.

The study will include a screening period from Day 28 to Day 1. The participants will be admitted to the clinical study site on Day 1 and receive the QL1209 or US-Perjeta® on Day 1. The participants will remain in the in-patient department for observation until the assessment on Day 3 is completed. Participants will return to the clinical study site for out-patient visits till Day 99 or upon early withdrawal.

In the study, validated test methods will be used to determine QL1209/Pertuzumab concentrations in PK samples at different visit points after infusion administration. Non- compartmental models will be used to calculate PK parameters and perform statistical analysis. Anti-drug antibody (ADA) and titer in immunogenicity samples will be determined using a validated test method, and neutralizing antibody (Nab) will be further tested for ADA-positive samples.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing QL1209 and US-Perjeta® in people with Breast Cancer, run by Qilu Pharmaceutical Co., Ltd..

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: opening soon, as of the sponsor's last update on 9 Oct 2026. 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?

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 Anne Monroe, MD (240-673-0500 ext. 1716, anne.monroe@pharmaron-us.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

AUC0-∞ (time frame: up to 99 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 9 Oct 2026.
