Solid dispersion of alectinib HCl: preclinical evaluation for improving bioavailability and establishing an IVIVC model.

Objective: Alectinib HCl (ALB-HCl) is a BCS class IV molecule with low solubility and low oral bioavailability. Owing to its low bioavailability, a high dose of ALB-HCl is recommended with food to meet clinical efficacy. Thus, there is a need for a delivery system to overcome the bioavailability concerns.
