Lilac Biosciences

Lilac Biosciences is a Redwood City-based biotechnology company specializing in the design and development of programmable protein therapeutics. The company's core technology platform focuses on creating conditionally activated biologics—often referred to as "masked" proteins—that remain inert in healthy tissue and are selectively triggered within the diseased microenvironment, such as the tumor microenvironment. This approach aims to broaden the therapeutic window of potent cytokines and antibodies by minimizing systemic toxicity while maximizing local efficacy. Lilac Biosciences is currently advancing a pipeline of candidates targeting oncology and inflammatory diseases, supported by expertise in high-throughput protein engineering and computational design.
