Abstract
Subcutaneous (SC) delivery of biotherapeutics is well established as a route of administration across many therapeutic areas and has been shown to be effective and well-tolerated. It can offer several advantages over intravenous administration. This notwithstanding, there remain critical development issues and knowledge gaps in SC drug delivery. To articulate and address these issues, the SC Drug Delivery and Development Consortium was convened in 2018 as a pre-competitive collaboration of industry experts in drug delivery, device development, and commercialization. In this review, we outline the Consortium's vision and mission in advancing the development of patient-centered biotherapeutics and establishing a collaborative organization that facilitates open sharing of information and gives voice to diverse viewpoints from SC experts across industries and disciplines. Additionally, we describe the current landscape and challenges associated with SC administration of therapeutic proteins (specifically monoclonal antibodies) and offer insights into potential solutions to these challenges within the context of 8 problem statements developed by the Consortium to highlight key gaps, unmet needs, and actionable issues. Current and future opportunities to accelerate progress in the field through technological advances and the development of drug delivery tools are also discussed.
