For pharmaceutical companies without their own facilities, choosing the right partner for latephase clinical trials and commercial production is a critical consideration in developing parenteral products.

This article examines some of the key criteria for selecting the right CDMO partner and includes a case study that shares some challenges involved in a late-phase technology transfer for a parenteral product.
