A powerful approach

We are leveraging the genetic principle of synthetic lethality and the power of our state-of-the-art CRISPR-based target discovery engine to discover and validate multiple novel targets each year. Our growing pipeline consists of programs for genetically defined subsets of cancers with limited treatment options.

Development Pipeline

Patient Selection
Clinical Trials
Anticipated Milestones
MTAP-del cancers
Phase 1/2
Phase 3
Initial clinical update 1H 2023
Phase 1/2
Patients: MTAP-del cancers
Anticipated Milestones: Initial clinical update 1H 2023
Development Pathway

Our Phase 1/2 first-in-human trial to evaluate TNG908 in patients with MTAP-deleted tumors is being conducted in two parts. The dose escalation phase will evaluate safety, efficacy, pharmacokinetics and pharmacodynamics in patients with locally advanced or metastatic cancer of any histology (with the exception of central nervous system tumors) with an MTAP deletion. After determining the optimally-effective dose for TNG908, we will further evaluate safety and efficacy in multiple tumor types in specific cohorts, including malignant peripheral nerve sheath tumor (MPNST – a rare sarcoma), non-small cell lung cancer, mesothelioma, cholangiocarcinoma, and glioblastoma.  In parallel, we will enroll a histology-agnostic arm to evaluate all other tumor types with MTAP deletion. Given that MTAP deletion occurs in approximately 10-15% of human cancers, we may open other histology-specific arms based on activity observed in the trial.

The FDA cleared the Investigational New Drug (IND) application for TNG908 in January 2022, and granted Fast Track Designation to TNG908. Additionally, the FDA granted Orphan Drug Designation for the treatment of MPNST with TNG908. Patients are being actively enrolled in the Phase 1/2 clinical trial. We expect to have an initial clinical update in the first half of 2023.

MTAP-del cancers
Clinical trial start mid-2023
Phase 1/2
Patients: MTAP-del cancers
Anticipated Milestones: Clinical trial start mid-2023
Development Pathway

The clinical development path for TNG462 is expected to be similar to TNG908, evaluating safety and efficacy in multiple tumor types in a Phase 1/2 clinical trial. Glioblastoma will be excluded from the Phase 1/2 trial as TNG462 does not cross the blood-brain barrier in preclinical models. We expect to initiate a Phase 1/2 clinical trial in mid-2023. We are planning to fully evaluate both TNG908 and TNG462 in clinical trials.

STK11-mut cancers
IND filing 1H 2023
Patients: STK11-mut cancers
Anticipated Milestones: IND filing 1H 2023
Development Pathway

The TNG260 clinical development plan will be among the first to combine the power of genetic patient selection and immunotherapy, evaluating patients with STK11 mutant cancers in a trial combining TNG260 and a checkpoint inhibitor. We plan to file an IND for TNG260 in the first half of 2023.

BRCA 1/2-mut cancers
IND filing mid-2023
Patients: BRCA 1/2-mut cancers
Anticipated Milestones: IND filing mid-2023
Development Pathway

Our preclinical work provides the basis for the future clinical trials of a USP1 inhibitor both as a single agent and in combination with PARP inhibitors in BRCA1/2-mutant cancers. We plan to evaluate USP1 as a single agent in patients with primary and secondary resistance to PARP inhibitors and in combination with PARP inhibitors in PARP-inhibitor naïve patients. Patient selection markers are being evaluated for BRCA1 WT populations, particularly in a subset of non-small cell lung cancer cell lines sensitive to USP1 inhibition. We plan to file an IND for this program mid-2023.

Gilead options and licensed targets not listed – learn more about our partnership below


Our global strategic collaboration with Gilead Sciences is focused on the discovery, development and commercialization of a pipeline of innovative targeted immune evasion therapies for patients with cancer. We are responsible for discovering and validating targets and for advancing select programs through clinical proof-of-concept. Gilead has options to worldwide rights on up to 15 of those targets. We retain the option to co-develop and co-promote the lead products for up to five of those programs in the U.S. with Gilead.

The collaboration, which was originally signed in 2018 and expanded in 2020, does not include our three lead programs. We retain all rights to those programs, along with the right to targets we have identified outside of the immune evasion space. We are committed to advancing the programs in our wholly owned pipeline into the clinic and beyond, as part of our mission to deliver the next generation of transformational targeted therapies to patients in need.
