New combo therapy aims to stop rare organ disease
NCT ID NCT07388602
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial tests whether adding the experimental drug SCTC21C to standard chemotherapy (bortezomib, cyclophosphamide, dexamethasone) works better than chemo alone for people newly diagnosed with AL amyloidosis. The study will enroll 90 participants and measure how well the treatment clears abnormal proteins from the blood and delays organ damage. The goal is to find a more effective way to control this rare disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SCTC21C (a drug given as an injection under the skin) combined with bortezomib, cyclophosphamide, and dexamethasone (standard chemotherapy)
- What this could lead to
- If successful, this combination could become a new standard treatment for newly diagnosed AL amyloidosis, improving blood response rates and delaying organ damage.
- What could go wrong
- This is an early Phase 3 trial with only 90 participants, so results may not apply to all patients. Adding a new drug also raises the chance of side effects.
