Compare subcutaneous delivery methods for trastuzumab in healthy men.

A Phase 1, Randomized, Two-Part, Parallel-Group Study to Assess the Bioequivalence of Subcutaneously Administered Trastuzumab Via Different Subcutaneous Delivery Platforms in Healthy Male Subjects

Phase 1 Interventional Genentech, Inc. · NCT07214766

We will test whether a handheld syringe/syringe pump with infusion set and an on-body delivery system deliver similar amounts of trastuzumab and are safe in healthy men.

What this trial studies

This two-part Phase 1 trial gives a single subcutaneous dose of trastuzumab to healthy male volunteers to compare pharmacokinetics, safety, and tolerability across two delivery platforms. Participants are randomized to receive trastuzumab via a handheld syringe/syringe pump with an infusion set or via an on-body delivery system, and blood samples will be taken over time to measure drug levels. Screening requires normal cardiac function (LVEF ≥55%), negative infectious disease tests, BMI 18–38 with weight ≤100 kg, and agreement to contraception, and subjects with significant medical histories or prior severe antibody hypersensitivity are excluded. Safety monitoring includes adverse event reporting and cardiac assessment, and the primary aim is to establish bioequivalence between the delivery methods.

Who should consider this trial

Good fit: Ideal candidates are healthy adult men who meet BMI and weight limits, have normal cardiac function and negative infectious screens, and have no significant medical conditions or history of antibody hypersensitivity.

Not a fit: People with a history of moderate-to-severe allergic reactions to monoclonal antibodies, significant medical comorbidities, cardiac dysfunction, or women and children will not benefit because they are excluded from this healthy-male Phase 1 study.

Why it matters

Potential benefit: If the devices are bioequivalent and well tolerated, this could allow more convenient and potentially at-home subcutaneous options for delivering trastuzumab to patients.

How similar studies have performed: Subcutaneous formulations of trastuzumab and on-body delivery systems for biologic drugs have previously shown comparable pharmacokinetics and improved convenience in other studies and approvals.
