Critical Testing Strategies for Autoinjector Drug Products
Executive Summary
As demand for self-administered therapies accelerates, autoinjectors, formally known as automated needle-based injection systems (NIS-AUTO), are playing an increasingly central role in modern medicine. These devices offer convenience, improve adherence, and support patient autonomy, while also easing the burden on healthcare systems. However, their dual role as both drug and device introduces a unique set of regulatory and performance challenges that must be addressed from early development through to commercialization.
Drawing from Solvias’ deep expertise in combination product testing, this white paper outlines best practices and evolving regulatory expectations across four critical domains: functional testing, extractables and leachables (E&L), container closure integrity testing (CCIT), and stability testing.
By integrating these elements into a cohesive CMC testing strategy, developers can streamline timelines, minimize regulatory risk, and confidently bring safe, effective, and reliable autoinjector products to market.
Autoinjectors on the Rise:
Opportunities and Risks in a Rapidly Expanding Market
Automated Needle-Based Injection Systems (NIS-AUTO), or autoinjectors, are medical devices designed for the self administration of injections of a premeasured dose of a particular drug by patients and for easy administration by healthcare professionals in emergency situations
The autoinjector drug product market is estimated to reach USD 134.27 billion in 2030 from USD 67.30 billion in 2024, growing at a CAGR of 12.2%. In 2021, autoinjectors accounted for the delivery of six of the 30 topselling drugs worldwide, representing approximately half of total global sales.
A significant contributor to this growth is the rising demand for Glucagon-like Peptide-1 (GLP-1) therapies. GLP-1 analogs, such as Ozempic®, Wegovi®, Rybelsus® and Mounjaro®, help regulate blood sugar and appetite, making them highly promising for treating both diabetes and obesity — conditions that impact over a billion people worldwide.
