A critical need
Great strides have been made in understanding the genetic drivers of cancer, but too many patients still lack effective treatment. Existing therapies target many of the activated oncogenes responsible for tumor growth but do not address the genetic alterations that fuel cancer by inactivating tumor suppressor genes and helping cancer cells evade killing by the immune system.
The next wave of targeted therapies
The first wave of targeted therapies revolutionized cancer care for patients whose cancers have specific activating mutations. These drugs target oncogenes such as BRAF, EGFR and ERBB2. However, genetic alterations that inactivate tumor suppressor genes are just as important in initiating and maintaining cancer growth and cannot be directly targeted.
Tango was founded in 2017 as a precision medicine company to address this broad unmet need and deliver the next wave of targeted therapies. We built a state-of-the-art CRISPR-based functional genomics target discovery platform and a powerful bio-analytic pipeline that integrating targets, pathways, genetic context and functional data to identify novel synthetic lethal targets for loss or inactivation of multiple tumor suppressor genes.
Powering our platform: Synthetic lethality
We are applying our approach in two core areas:
Tumor suppressor gene loss
Most cancers are fueled in part by genetic changes that disable the protective genes meant to suppress tumor growth called tumor suppressor genes. The loss of function those genes caused by genetic alterations allows the cancer to grow – but it also makes the cancer cells vulnerable to synthetic lethal drug targeting. Our integrated discovery platform uncovers the vulnerabilities that arise from the loss of a tumor suppressor gene in specific cancer types. We then leverage these insights to develop novel drugs that destroy cancer cells, but spare normal cells.
A normal immune system should recognize cancer cells as foreign and destroy them. However, cancer cells have genetic changes that allow them to evade the immune system. We discovered that there are multiple known tumor suppressor genes that, when genetically altered, activate genes and pathways that result in immune evasion, manifest clinically as resistance to checkpoint inhibitors. This approach opens a target space with powerful potential in defined genetic subsets of cancer.
Patients drive our process
We have an efficient and productive discovery and development process that utilizes high-throughput CRISPR-based functional genomics screening to identify synthetic lethal vulnerabilities in cancer cells with specific tumor suppressor gene loss. We focus on diseases with high unmet need where patients share a common genetic context. We are committed to developing precise, effective and safe therapies for the people with cancer who need them most. Explore our approach:
