This product candidate that has the potential to improve the therapy for a cohort of cancer patients in a high-value field where no new or improved drugs have been registered for many years. In addition, we have tested this formulation A in previous studies and can better predict the findings compared to the studies that have been based on completely new untested formulations,” says Per Andersson, CEO of Xspray Pharma.

Xspray Pharma’s product will be administered at a lower dose strength compared with Sprycel® but with the same availability. Bioequivalence studies with Xspray Pharma generic product candidate, formulation C, where the objective is to demonstrate bioequivalence with Sprycel®, will be initiated this summer. The findings will form the basis of an application for market approval in the US under the ANDA regulatory pathway.
