Releviate Therapeutics is addressing unmet needs in chronic pain. We offer first-in-class inhibitors whose development is rooted in actual pain pathology and in directly inhibiting pain pathways. Releviate Therapeutics directly targets pain.

There are two major products: RLVT-9-01 (anti-MMP-9 antibody) and RLVT-14-02 (anti-MMP-14 antibody).

Small-molecule-based synthetic inhibitors are non-selective and exhibited multiple off-target effects. Due to the high similarity between matrix metalloproteinases (MMPs), all small-molecule-based inhibitors failed clinical trials. Releviate Therapeutics was able to address the specificity issue by using specially developed and selected human monoclonal antibodies against MMP-9 and MMP-14, respectively.

MMPs consist of a large family of endopeptidases that require Zn2+ for their enzyme activity. MMPs play a critical role in inflammation through the cleavage of the extracellular matrix proteins, cytokines, and chemokine MMP inhibitors have been developed to target different kinds of inflammation-related diseases, such as arthritis, atherosclerosis, periodontitis, and cancer.

Although there are more than 20 members in the MMP family, the gelatinases MMP-9 and MMP-2 are two of the best-studied family members. After secretion, MMP-9 and MMP-2 are found in the extracellular matrix, cerebrospinal fluid, and serum. MMP-9 and MMP-2 are activated by other proteases. For instance, MMP-9 is activated by plasminogen/plasmin and MMP-3, and MMP-2 is activated by MMP-14. The activity of MMP-2 and MMP-9 can be easily detected using the gelatin-substrate zymography assay. While MMP-2 is constitutively expressed in many tissues, MMP-9 is highly inducible. The activity of MMPs is regulated by endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMP). For example, the activity of MMP-9 and MMP-2 is inhibited by TIMP-1 and TIMP-2, respectively.

The timeline below highlights our technology development and related publications. Releviate technology is the product of 20 years of extensive collaborative work between basic, translational, and clinical scientists from Duke University School of Medicine (Department of Anesthesiology), UC San Diego School of Medicine (Department of Anesthesiology), UC Riverside (Department of Bioengineering), and Sanford Burnham Research Institute (Biochemistry of MMPs).
