Our BioSeizer lipid-based formulation platform is our proprietary, lipid-based drug delivery system which can entrap both small molecules and large molecules and then slowly release them. The release profile of encapsulated compounds or proteins can be adjusted by modulating the compositions of lipid components and altering the manufacturing processes. Unlike other extended release formulations based on substances such as poly lactic-co-glycolic acid, BioSeizer formulations allow local injections into sensitive tissues such as the eye or small joints using much smaller gauge needles. Our manufacturing process uses sterile filtration at the near-end stage, rather than an entirely aseptic process from raw material to final product. TLC599, TLC399, and TLC590 utilize our BioSeizer technology. We believe the advantages of BioSeizer compared to other formulation technologies include: • Ability to deliver biologics (such as antibodies) or small molecules; • Ability to design the API’s releasing profile; • Providing immediate availability of free API; • Prolonging the retention time of APIs at the disease site; • Reducing the side effects of API due to systemic exposure; • Fully biodegradable components; and • Protection by composition of matter patents.
