Statement of the Problem: A wide variety of bacteria can cause severe infections. Many of these bacteria are or have become resistant to many commonly used antibiotics. Infections due to drug-resistant bacteria require treatment with new types of antibiotics. Phage endolysins differ from standard-of-care antibiotics with regard to their potency, speed, specificity, and activity against antibiotic-resistant strains. Therefore, phage endolysins represent a promising research target for the discovery and development of novel antibacterial therapeutic agents. Materials & Method: We developed phage endolysin SAL-1 using genetic information of staphylococcal bacteriophage SAP-1. For current and future clinical studies of SAL-1, we performed the development of its efficient production process and ELISA assay method, preformulation study and its characterization. Findings: We established an efficient soluble production process for SAL-1 and ELISA assay method to be used in pharmacokinetic study. In addition, various characteristic of SAL-1 including pI, antibacterial activity were identified. Furthermore, appropriate formulation providing acceptable storage- and handling-stability was developed. Conclusion: Essential prerequisite technologies for conducting clinical studies for SAL-1-containing drug candidate were developed. We anticipate that this presentation will provide incentives for developing phage endolysin-based antibacterial agents to combat other bacterial infections.
