Biosimilar CT-P6 tested against herceptin in healthy volunteers
NCT ID NCT06687928
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 1 trial compared a single dose of CT-P6, a biosimilar of the cancer drug trastuzumab, to the approved Herceptin in 200 healthy men. The goal was to see if the two drugs behave similarly in the body and have comparable safety. Results will help determine if CT-P6 can be used as a more affordable alternative.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CT-P6 (a biosimilar of trastuzumab) and Herceptin (trastuzumab)
- What this could lead to
- If successful, this could show that CT-P6 works similarly to Herceptin, potentially offering a more affordable treatment option for certain cancers.
- What could go wrong
- This is an early-phase study in healthy men, not patients. It only checks how the drug moves through the body and safety, not whether it treats disease. Results may not predict real-world effectiveness.
