CatchMe Therapeutics

CSO: Dr. Yael Tsalenchuck

CatchMe Therapeutics develops a novel class of precision medicines that targets the epitranscriptome machinery.

The emerging field of RNA epitranscriptomics refers to a set of RNA modifying proteins and modified-RNA binding proteins that control different aspects of RNA biology and holds great potential for new cancer therapeutics.

Scientific Background

During the past decade, the emerging field of RNA posttranscriptional modifications (epitranscriptomics) took a big leap forward. New discoveries are being made every day, and the ability to manipulate different components of the epitranscriptome machinery holds great potential for new therapeutics. N6-methyladenosine (m6A) has been identified as the most abundant mRNA modification. The m6A modification is processed by a complex network of proteins that add (writer), remove (eraser), and bind (reader) to mRNA molecules carrying this modification. The importance of m6A RNA modification is well demonstrated in different human pathologies, including cancer and viral infections.  Many studies have shown that m6A, and the proteins that are involved in its processing, plays an important role in various cancer types like lung cancer, hepatocellular carcinoma, glioblastoma, renal cell carcinoma and acute myeloid leukemia (AML). While the m6A machinery robustly regulates the initiation, propagation, survival, and replication of many cancers, currently there is no drug or any available therapy targeting this machinery.

Indication

Our first target indication will be acute myeloid leukemia (AML). AML is one of the most common and lethal hematopoietic malignancies. So far, the current treatment for AML is still insufficient and there is a significant unmet medical need for high-risk naïve patients and relapse refractory patients. The expression of m6A modifying proteins is upregulated in AML cells; Depletion of the m6A writer proteins, induces the differentiation and apoptosis of myeloid leukemia cells and delays the occurrence of leukemia in mice.  Inhibition of m6A reader protein in AML, eradicates cancer cells and leukemic stem cells (LSC) without compromise normal hematopoiesis.

Competitive Advantage

Several companies targeting the RNA epitranscriptome, were established in the last couple of years.  All are in pre-clinical stage and develop small molecule-based inhibitors. Small molecule inhibitors can target multiple homologous methyl binding proteins and generate unspecific and undesired biological reaction. Our unique solution for specific inhibition is based on the in-vivo biological binding preference of our target proteins. In addition, our unique and versatile platform can be easily expended to target different methyl binding proteins and different indications.
