Next-Generation Long-Acting Microsphere Platform:
Ultra-precise release control, optimized therapeutic effects, and scalable manufacturing flexibility
Daewoong Pharmaceutical’s CURE® (Controlled Ultra-precision Release & Effect-Optimized Microsphere) technology is a next-generation drug delivery platform engineered not only to deliver drugs, but to achieve optimal therapeutic outcomes for patients.
By overcoming conventional technical limitations, CURE® precisely controls drug release and maximizes efficacy, setting a new standard for long-acting injectable formulations.
More than a conventional microsphere technology, CURE® represents an advanced platform designed to enhance patient quality of life and redefine the future of drug delivery.
Controlled Ultra-precision
Release
CURE® enables the precise design and modulation of drug release profiles, allowing drugs to be released at a consistent and predictable rate in the body. This minimizes initial burst release-related side effects while ensuring stable and sustained therapeutic efficacy.
Effect Optimized
The engineered microspheres optimize drug concentration and duration of action to maximize therapeutic effectiveness. This allows for enhanced efficacy even at lower doses while significantly improving patient adherence.
Ready to Scale
CURE® offers a highly flexible and scalable production system, enabling seamless transition from small-scale clinical sample production to large-scale commercial manufacturing. This ensures consistent product quality across all stages of development while maintaining operational efficiency.

The value of CURE® lies in its ability to consistently reproduce precisely engineered drug release profiles—from early-stage research to full-scale commercial production.
Daewoong Pharmaceutical has established integrated process capabilities and infrastructure that enable:
These capabilities are realized through a fully integrated internal workflow—from microsphere fabrication and solvent removal to particle size control and release characterization—where each step is optimized to maintain the core performance of long-acting delivery systems.
A core manufacturing technology that forms O/W or W/O/W emulsions using active pharmaceutical ingredients and biodegradable polymers, followed by solvent removal and solidification to produce long-acting microsphere formulations.

A process in which a solution of active ingredients and polymers is atomized and rapidly dried to produce sustained-release microspheres.

Daewoong systematically evaluates and optimizes a wide range of formulation compositions and process conditions at the research stage, identifying and accumulating key process parameters that influence long-acting release performance. This data-driven approach enhances understanding of formulation behavior and serves as the foundation for consistent technology transfer into development and manufacturing stages.

The manufacturing process is designed to ensure stable control of critical parameters that determine microsphere release characteristics, regardless of production scale—enabling consistent translation of R&D performance into commercial production.

These technologies and manufacturing capabilities do not remain limited to drug delivery performance, but are ultimately integrated into a Dual Chamber Syringe (DCS) system that also reflects usability at the actual point of administration.
The DCS is a dedicated injection device designed based on the physical characteristics and injection behavior of microsphere formulations, ensuring both stable injection performance and user convenience during administration.

Filling Infrastructure
Daewoong possesses in-house capabilities to design and develop dedicated DCS injection devices that take into account microsphere formulation characteristics—such as particle size distribution, dispersion stability, and injection resistance—thereby achieving both stable injection behavior and user convenience simultaneously during administration.
Daewoong holds patents for DCS container structures designed to maintain formulation stability while also ensuring usability during handling and administration, thereby securing differentiated device competitiveness.
By applying automated filling processes optimized for DCS device characteristics, Daewoong improves filling precision and enables minimization of batch-to-batch variability.
