Subcutaneous conversion removes intravenous delivery chains entirely
Hyaluronidase-enabled formulations now permit large-volume subcutaneous administration of biologics that previously required intravenous infusion, and approvals have accelerated sharply across oncology and immunology since 2024. Roughly 23% of intravenous biologic regimens have a subcutaneous equivalent available today. Each conversion removes a pump, a vascular access device, an administration set and frequently a nursing visit at the same time. On-body wearable injectors capture part of the displaced value at 13.2% growth, but total device content per patient falls rather than rises through the transition. No device company holds any influence over those formulation decisions or advance visibility into them.
