Could a cheaper keytruda copy work for lung cancer?
NCT ID NCT06268613
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial compares a biosimilar drug (SB27) to the standard cancer immunotherapy Keytruda in 163 people with stage II-IIIA non-small cell lung cancer who have already had surgery and chemotherapy. The main goal is to see if the body processes SB27 the same way as Keytruda. If successful, SB27 could become 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
- pembrolizumab (a biosimilar version of Keytruda)
- What this could lead to
- If SB27 works like Keytruda, it could offer a more affordable treatment option for early-stage lung cancer after surgery.
- What could go wrong
- This is an early phase 1 trial focused on drug levels in the blood, not yet on long-term outcomes. The biosimilar may not prove equally effective or safe.
