Some investment analysts have been skeptical about Prochymal's future. In 2009, two late-stage clinical trials failed to show the drug was more effective overall than a placebo in treating the disease, though it showed promise in certain subgroups of patients.
Since then, the company has mined data from all its clinical trials to show that in patients with severe refractory acute GvHD – those who have more or less failed all other therapies – Prochymal demonstrated a clinically meaningful response at 28 days after therapy began in 61-64 per cent of patients.
In addition, treatment with Prochymal resulted in a statistically significant improvement in survival when compared with a historical control population of pediatric patients with refractory GvHD.
The Canadian authorities approved the drug on the basis of that data, the company said.
