Detailed Description

This is a Phase 1, randomized, double-blind, two-arm, parallel-group trial comparing the pharmacokinetics (PK), immunogenicity, safety, and tolerability of Bmab3000 (test) and Herceptin Hylecta (reference) after a single subcutaneous (s.c.) dose.

A total of 150 healthy male participants (75 per arm) will be enrolled to ensure 138 evaluable subjects. Participants will be randomized in 1:1 using stratified block randomization based on baseline body weight (≥50-≤75 kg and >75-≤100 kg).

Each participant will be involved in the study for approximately four months, which includes one screening visit, a 3-night inpatient stay, and 16 scheduled outpatient follow-up visits. Participants will attend a screening visit (Day -28 to Day -1) to confirm eligibility. This will include obtaining informed consent, medical history, physical examination, vital signs, biometric measurements, ECG, echocardiogram, and blood and urine tests, as well as drug and alcohol screening. Eligible participants will be admitted to the study site on Day -1 for pre-dose assessments to confirm continued eligibility. On Day 1, participants will receive a single subcutaneous injection of either Bmab3000 or Herceptin Hylecta. During the inpatient stay (Days -1 to 3), participants will undergo continuous safety monitoring, including regular vital signs, ECGs, injection site checks, and blood sampling for pharmacokinetic, safety, and immunogenicity assessments. After discharge, participants will return for outpatient visits till Day 85 for continued safety monitoring, blood sampling for pharmacokinetic and immunogenicity analyses, and ECGs and vital sign assessments. The final visit on Day 91 will include a full physical examination, echocardiogram, ECG and blood sampling for pharmacokinetic & immunogenicity analyses and final laboratory evaluations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
