MabTrix is a preclinical stage biopharmaceutical company aiming to develop an innovative, function-blocking therapeutic monoclonal antibody (MAb) for inflammatory bowel disease (IBD) as the initial indication. The company’s mission is to develop a novel MAb that specifically inhibits enzymatic activity of matrix metalloprotease (MMP) 9 by binding to the catalytic site of the activated enzyme.

MabTrix was established in the FutuRx incubator in December 2015.


MMPs are a group of zinc-dependent enzymes that can irreversibly degrade complex substrates in the extracellular matrix, cleave chemokines, and participate in many homeostatic processes. These enzymes play an important role as initiators of signaling cascades, and their imbalanced activity is often associated with inflammatory diseases and cancer. MMPs show distinguishable substrate specificities, and contribute to epithelial and endothelial barrier disruption in IBD and enable immune cells to infiltrate tissues. MMP-9 is a multi-domain enzyme that plays crucial roles in inflammation and in tumor invasion and metastasis, and regulates signaling pathways that control cell growth, survival, invasion, inflammation and angiogenesis.


MabTrix’ unique approach is based on a novel technology, leading to the generation of MAbs binding to the catalytic site of activated MMP-9. This strategy enables targeting the in-vivo activity of dysregulated MMP-9 by mimicking the natural mechanism employed by TIMP inhibitors that bind the active site. Along with the general superior specificity of MAbs compared to small molecules, this should increase selectivity to MMP-9 compared to other MMPs, thus minimizing unwanted adverse effects due to pan-MMP inhibition. Binding of MAb specifically to the activated form may also contribute to an improved safety profile and to high treatment efficiency by avoiding the ‘sink effect’ of binding to systemic non-activated MMP-9.


IBD represent chronic incurable inflammatory disorders of the gastrointestinal tract. The two most common inflammatory bowel diseases are ulcerative colitis and Crohn’s disease, both characterized by an abnormal response to the body’s immune system and manifest by severe diarrhea, pain, fatigue and weight loss. IBD can be debilitating and sometimes leads to life-threatening complications. Current therapeutic agents consist of anti-inflammatory drugs as well as immune system suppressors in the form of small molecules and biologics. Available biologics include MAbs targeting specific pro-inflammatory cytokines and integrins. These drugs achieve only partial efficacy, have considerable side effects and drug-resistance is observed in numerous patients. Thus, there is a clear unmet clinical need for new, innovative therapeutic approaches.

The global IBD market is growing rapidly and is expected to exceed $10B in 2022 with increased market share for biological agents, specifically therapeutic MAbs.
