Trellis Bioscience is a clinical-stage private biotech company discovering and developing human antibodies against infectious diseases and cancer. TRL1068 completed a landmark Phase 1 clinical study in patients with chronic periprosthetic joint infections. TRL345 is in a Phase 1 safety study in healthy adult volunteers. While initially focusing on anti-viral antibodies, the Company built a robust, semi-automatic, well validated platform known as CellSpot™ for which the needle in the haystack analogy perfectly applies to describe the unique ability to identify and recover 1 out of 1 million B-cells that produce desirable human antibodies for therapeutic use. At the end of 2009, Trellis closed a landmark deal to license a pre-IND stage anti-RSV mAb to MedImmune. In 2014, we licensed our influenza A and B program to ContraFect, Inc. Current programs include an anti-human cytomegalovirus (HCMV) mAb for transplant patients, a bacterial biofilm disrupting human antibody for the treatment of chronic Gram+ and Gram- infections, and human antibodies against immune check point modulators (ICMs) including LAG-3, TIM-3, KIR2, B7-H3, VISTA and CEACAM-1 for the treatment of cancer. The CellSpot platform allowed us to discover fully matured IgG anti-ICM antibodies from healthy donors with no known cancer. The immune surveillance concept suggest that the immune system of healthy individuals fights emerging tumors. leaving a footprint in the memory B cell compartment, which is detectable by a sensitive technology platform such as CellSpot. The cancer mAbs were licensed to Relevant Biosciences.

A-Cube was acquired by Trellis Bioscience in 2013.A-Cube is a leader in identifying B-cell epitopes, which are the binding sites for monoclonal antibodies. By generating comprehensive B-cell epitope maps of proteins we develop plans to de-immunize therapeutic proteins. We have successfully lowered the immunogenicity score in a model protein and currently focus on de-immunizing factor VIII and enzyme replacement therapies (ERTs). We expect that a de-immunized factor VIII therapy would not be inhibited by neutralizing antibody (inhibitors) that have developed in a subset of hemophilia patients after exposure to current factor VIII therapy. This application potentially addresses a huge medical need for hemophilia patients.ERT therapy is often accompanied by the occurrence of neutralizing antibodies. Our novel approach to de-immunize ERTs will reduce the neutralizing effect of neutralizing antibodies that already exist in patients with lysosomal storage diseases.Other applications to de-immunize proteins include gene therapy vector AAV. In gene therapy, neutralizing antibodies are a limiting factor. We also apply the technology in an opposite manner, namely to concentrate immunogenic parts of viral proteins in vaccine prototypes. We are currently creating a blueprint to a universal influenza vaccine. The third application has been reduced to practice several times: raise antibodies against newly identified B-cell epitopes. While differentiating against traditional wet lab technologies through a more focused and direct approach, in addition our technology helps to prioritize epitopes and generate antibodies against novel B-cell epitopes.

A-Cube's mission:Apply proprietary bioinformatics technology in various areas to generate IP, license/partner these programs with pharma/biotech companies Partner technology platform with pharma/biotech companies to improve their mAbs and vaccines in the pipeline, and to generate new IPDevelop two drug candidates and advance them to generate meaningful clinical signals, then seek partnership for development and commercialization

Aridis Pharmaceuticals focuses on product candidates targeting infectious diseases and on advanced formulation and delivery technologies to improve the effectiveness of proprietary products. One of Aridis's product candidates is Aerucin, a human monoclonal antibody against Pseudomonas aeruginosa. It is in a pre-IND stage and has the potential to be best in class for the treatment of pseudomonas infections which are an increasing burden to the healthcare system. The mechanism of action is novel and appears suitable to combination therapy with antibiotics.
