Could a machine beat the human hand for Pain-Free injections?
NCT ID NCT07533526
First seen Apr 21, 2026 · Last updated Jun 23, 2026 · Updated 8 times
Summary
This study compares two ways of giving a large-volume subcutaneous injection of pertuzumab and trastuzumab (Phesgo) to breast cancer patients: one using a machine that injects at a constant speed, and the other using a nurse's hand. Forty female patients will receive both methods in different treatment cycles to see which causes less pain. The goal is to find a more comfortable injection technique.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
pertuzumab and trastuzumab (Phesgo)
What this could lead to
If it works, this could lead to a less painful way to give large-volume subcutaneous injections, improving the treatment experience for breast cancer patients.
What could go wrong
This is a small, early-stage study with only 40 patients, so results may not apply to everyone. The manual injection is timed to match the machine, so differences in pain may be small.
Conditions
