Market Dynamics

Driver - Surging diabetes and cancer cases solidify role of injectable systems

Increasing prevalence of diabetes, cancer, and autoimmune disorders is directly augmenting demand for injectable drug delivery systems due to the nature of these diseases and the therapies used to treat them. In 2024, for example, more than 540 Mn people globally were living with diabetes, according to the International Diabetes Federation. The number is expected to surpass 640 Mn by 2030. Injectable insulin and GLP-1 receptor agonists such as semaglutide have become standard treatment options. Hence, companies are extending production of autoinjectors and wearable injectors to facilitate self-administration.

In oncology, injectable biologics such as checkpoint inhibitors and monoclonal antibodies dominate cancer immunotherapy pipelines. New cancer cases are predicted to surge from 20 Mn in 2022 to over 35 Mn by 2050, found the World Health Organization (WHO). Therefore, injectable drug formats remain essential due to their ability to bypass the gastrointestinal tract and deliver rapid, systemic effects. Companies are also launching subcutaneous formulations of drugs traditionally given intravenously such as Roche’s Phesgo, to enhance convenience.

Restraint - Manufacturing complexities create supply bottlenecks

The complexity of manufacturing injectable drug delivery systems is creating significant supply chain constraints, particularly as demand rises for biologics and self-administered therapies. These systems require high-precision engineering, sterile fill-finish operations, and rigorous quality control. All of these tend to lengthen production timelines and raise costs. Start-ups and small-scale biotech firms developing novel injectables often face significant hurdles in scaling up.

It is because few contract manufacturers have the specialized infrastructure to handle complex devices such as wearable injectors or dual-chamber syringes. This further creates a reliance on a limited pool of CDMOs, extending lead times and raising costs. As per a recent study, the average lead time for sterile injectable fill-finish slots at key CDMOs extended beyond 18 months in 2023, delaying market entry for several therapies.

Opportunity - Rising preference for at-home treatment to open new avenues

The accelerating trend toward self-administration is fundamentally boosting the injectable drug delivery market growth, states Persistence Market Research. It is creating demand for patient-centric devices that prioritize ease of use, safety, and convenience. With chronic diseases such as rheumatoid arthritis and diabetes requiring long-term treatment, patients prefer administering medications at home rather than visiting clinics. This shift has led to a surge in the adoption of self-injectors that are specifically designed to facilitate accurate, consistent dosing with minimal medical supervision.

Wearable injectors are gaining impetus due to demand for at-home administration of biologics and high-viscosity drugs. The growth of digital health integration is also creating lucrative opportunities. Connected injectors equipped with Bluetooth are enabling dose-tracking and real-time adherence monitoring through mobile apps. This convergence of drug delivery and digital health is not only empowering patients but also attracting interest from providers seeking value-based care models.
