01 about

Enlaza is creating a groundbreaking new class of protein therapeutics that deliver more efficacious and safer treatments for patients.

Enlaza’s breakthrough War-LockTM technology enables generation of unique, highly-selective biologic drugs that are engineered to become warheads with the capacity to irreversibly lock to disease related targets. We leverage our novel synthetic biology platform, coupled with proprietary amino acids, to precision-engineer biological medicines with improved efficacy and safety profiles.

Irreversible binding, or covalency, has the potential to improve the performance of numerous therapeutic modalities through increased efficiency, unprecedented target modulation and eliminating the need for continuous systemic exposure. Our differentiated and proprietary War-Lock technology expands the therapeutic window to enable safer, more effective therapies.

Standard protein therapeutics are based on scaffolds that bind specifically, but reversibly, to the therapeutic target of interest. To maintain the desired outcome, dosing must be long-lasting or continuous to compete with the inherent off-rate of the interaction. Enlaza technology allows novel modalities to achieve sustained occupancy and prolonged biologic effect with minimal systemic exposure.

Enlaza’s approach introduces a proprietary unnatural amino acid that promotes covalency to the disease target with a subtle structural change. The introduction of the unnatural amino acid maintains the stability and drug-like properties of the therapeutic agent. With standard engineering techniques, Enlaza technology is widely applicable across protein-drug formats and can be readily introduced to create an optimal War-Lock to address disease-target biology.

02 Science

Enlaza’s platform technology enables a new generation of covalent-acting, “War-Lock” biologics with improved efficacy and safety profiles.

Enlaza’s groundbreaking technology enables the engineering and production of a powerful new class of biologic drugs. The technology works via incorporating unnatural amino acids with expanded chemical function into protein drugs, allowing covalent bond formation between the drug and its target. Our proprietary amino acid subunits can be incorporated into virtually any protein format without impacting the exquisite therapeutic specificity for the desired targets.

When un-bound in circulation, War-Locks are latent and un-reactive. Only upon specific target engagement is the chemistry activated, rapidly forming a covalent bond between the drug and the target.

Enlaza is developing the novel War-Lock modality to overcome liabilities of current biologic drugs. Standard protein drugs built from native amino acids cannot be easily tuned for specific delivery to diseased areas, leading to sustained exposure to healthy tissue. This leads to limited efficacy, healthy tissue damage, and toxicity. In contrast, Enlaza’s technology allows engineering of protein therapeutics that sustain target occupancy without long-term systemic exposure.

Our compounds distribute rapidly, lock irreversibly to disease-relevant targets, and achieve high exposure in diseased tissues. Any un-bound drug is cleared rapidly, thereby minimizing exposure to healthy tissues. The novel and differentiated War-Lock pharmacological profile enables separation of efficacy from off-target effects to enable safer and more effective therapies.

03 Team

Enlaza is led by an experienced biopharmaceutical team with deep scientific expertise.

“We expect covalency will become a standard part of the tool box in the field of therapeutic proteins and biologics. We are excited to use this technology to transform drug discovery and provide meaningful therapeutic benefits for patients.”

Lei Wang, Ph.D.

Scientific Advisor, Professor UCSF

Lei Wang is a Professor in the Department of Pharmaceutical Chemistry, the Cardiovascular Research Institute, and the Helen Diller Family Comprehensive Cancer Center at University of California San Francisco. His Ph.D. research at UC Berkeley, mentored by Peter G. Schultz, achieved the first expansion of the genetic code to include unnatural amino acids (UAAs) in 2001, for which he was awarded the Young Scientist Award by the Science magazine. After postdoctoral training with Roger Y. Tsien (Nobel Laureate in Chemistry), Wang started his group at the Salk Institute in 2005, and moved to UCSF in 2014. His group has developed new methods for the expansion of the genetic code in a variety of cells and animals, and has discovered that release factor one is nonessential in E. coli.

Recently, Wang pioneered the concept of proximity-enabled bioreactivity and achieved the genetic encoding of latent bioreactive UAAs in live systems. This new class of UAAs enables biospecific reactivity, inaccessible to proteins before, to be precisely introduced into biosystems, opening the door to harnessing covalent chemistry for protein engineering and biological research in vivo.
