đŸ”¬ Research spotlight: same trial, same data, two different readings.
The trial is HOPE-3. It's a phase 3, randomized, double-blind, placebo-controlled study of deramiocel, an investigational cell therapy made from donor heart cells (cardiosphere-derived cells, not MSCs). It enrolled 106 people aged 10 and older with Duchenne muscular dystrophy: 54 got deramiocel, 52 got placebo. The maker, Capricor, funded it.
Reading one: the paper. Published in The Lancet in 2026, it reported that the primary endpoint, upper-limb function at 12 months measured as a percent change, favored deramiocel by 4.55 percentage points (p=0.029). The authors reported a safety profile similar to placebo.
Reading two: FDA's reviewers. Their briefing document says that analysis plan was finalized one day before the database was locked and the data unblinded. Using the analysis originally prespecified, FDA found a difference of 0.66 points (p=0.24) and called it neither statistically significant nor clinically meaningful.
In July 2026, an FDA advisory committee voted 9 to 3 "no" on whether the evidence was strong enough for the heart-related use the company had proposed. That vote is non-binding. The company says FDA's target decision date is November 22, 2026.
Why should you care? Because how a study is analyzed can change what it seems to show. That's why researchers are supposed to write the plan down before they look.
So the next time someone says "a study showed," ask one question: was that the analysis they planned up front?
More research, and FDA's review, will tell us more. This is about one investigational product. It doesn't carry over to any other cell product.
We walked through both readings on the blog. Link in bio.
