Pharmaceutical data: Stability of the drug in the pen system (temperature, shaking, light exposure), compatibility (leachables/adsorption studies), and delivery performance (dose accuracy, repeatability) must be demonstrated.

 

Device performance: Mechanical reliability (drop testing, button lifespan), dose accuracy (full-range testing), and safety (needle protection, misuse prevention) are verified according to the ISO 11608 series of standards.

 

Human factors engineering (Usability): Simulation of real-world usage scenarios is mandatory to ensure safe and independent operation by patients of all ages and abilities (e.g., those with visual impairments).

 

Good Manufacturing Practices (GMP/CGMP)

 

Sterility assurance: Drug filling (Grade A environment under Grade C background) and needle assembly must comply with sterile process requirements.

 

Process control: Dimensional tolerances and assembly torque of key components (springs, gaskets) directly affect dose accuracy and require SPC statistical monitoring.

Supply chain traceability: A Unique Device Identification (UDI) system must be established for device components (cartridges, pen cores, needles).

 

Post-Market Surveillance Focus

 

Adverse events related to drug-device interactions (e.g., mechanical failures causing under-/over-dosing, needle clogging).

 

Real-world monitoring of dose accuracy (especially for high-concentration formulations).

 

Compliance of patient training materials (e.g., EMA requires multimedia operation guides).

 

Features of Chinese Regulations (NMPA)

 

The "Rules for the Unique Device Identification System" require UDI labeling for prefilled pens.

The "Technical Guidelines for Drug-Device Combination Products" clarify the evaluation pathway for drug-device interactions.

 

New regulations in 2023 strengthen requirements for human factors engineering and usability testing, aligning with international standards.

 

III. Typical Case Studies

 

Insulin pens: From first-generation pens with replaceable cartridges to smart connected pens, continuous optimization of dose memory and data tracking functions meets personalized diabetes management needs.

 

Growth hormone pens: Hidden needle designs significantly reduce injection anxiety in children, while automatic recording functions assist in growth curve monitoring.

 

GLP-1 receptor agonist pens: Benaglutide prefilled pens use a multi-dose prefilled design to simplify medication processes; semaglutide pens feature a dose selector separated from the injection button to reduce operational errors.

 

Injection pens have reshaped the treatment experience for protein-based drugs through technological innovation, becoming a core tool in chronic disease management. Their development and production must strictly adhere to the dual regulatory framework for "drug-device combination products," ensuring pharmaceutical efficacy and device reliability while continuously optimizing human-machine interaction design and smart functions. As regulatory agencies like the NMPA refine requirements for combination products, pharmaceutical companies must strengthen interdisciplinary collaboration (pharmaceuticals + engineering + human factors science) and build a quality system covering the entire lifecycle to promote the implementation of safer, more accurate, and more convenient protein drug delivery solutions.
