VRN19: A novel USP1 Inhibitor with anti-tumor efficacy and favorable safety profile
(AACR 2025)
- "In the BRCA1-mutated CDX model (MDA-MB-436) and PDX with resistance to PARP inhibitors, VRN19 demonstrated synergistic effect with PARP inhibitors, particularly with olaparib, and showed efficacy comparable to KSQ-4279 without toxicity. In a 2-week toxicity study in rats, administration of 300 mg/kg VRN19 showed no significant changes in anemia markers, such as RBC, Hb, and reticulocytes, nor hepatotoxicity indicators like GGT and bilirubin. However, administration of 300 mg/kg KSQ-4279 significantly elevated anemia-related markers and GGT levels, consistent with the adverse events observed in clinical trials with KSQ-4279.In conclusion, VRN19 is a promising novel USP1 inhibitor with favorable safety and improved therapeutic outcomes."

Discovery of TNG-6132, a potent, selective, and orally bioavailable USP1 inhibitor.
(PubMed, Bioorg Med Chem Lett)
- "This inhibitory effect translates into in vitro cellular viability defects in a BRCA1-mutant breast cancer cell line, as well as an in vivo pharmacodynamic (PD) response and tumor growth suppression in a mouse xenograft efficacy model. Additionally, we report an X-ray co-crystal structure of TNG-6132 (18) bound in the USP1-UAF1 complex, a result that furthered our understanding of the role played by key elements of the pharmacophore of this chemotype as well as its mechanism of inhibition of USP1."

Characterization of TNG348: a selective, allosteric USP1 inhibitor that synergizes with PARP inhibitors in tumors with homologous recombination deficiency.
(PubMed, Mol Cancer Ther)
- P1/2 | "Importantly, our data in human cancer models further show that the addition of TNG348 to PARPi treatment can overcome acquired PARPi resistance in vivo. While the clinical development of TNG348 has been discontinued due to unexpected liver toxicity in patients (NCT06065059), the present data provides preclinical and mechanistic support for the continued exploration of USP1 as a drug target for the treatment of patients with BRCA1/2 mutant or HRD cancers."

Tango Therapeutics Announces Discontinuation of TNG348 Program
(Businesswire)
- P1/2 | N=140 | NCT06065059 | Sponsor: Tango Therapeutics, Inc. | "Tango Therapeutics, Inc...today announced that it will discontinue development of its TNG348 program....TNG348 was being studied in a phase 1/2 clinical trial evaluating safety, pharmacokinetics, pharmacodynamics and efficacy as a single agent and in combination with olaparib, a PARP inhibitor, in patients with BRCA1/2-mutant and other HRD+ (homologous recombination deficient) cancers. Grade 3/4 liver function abnormalities were observed in patients remaining on study longer than eight weeks, leading to the decision to terminate the program."

TNG348 is synergistic with PARP inhibitors in tumor models with elevated replication stress
(AACR 2024)
- "We previously showed that the anti-tumor activity of USP1 inhibition results from disruption of the translesion synthesis DNA damage tolerance pathway, a mechanism of action that is functionally distinct from base excision repair targeted by PARPi...For example, overexpression of oncogenes known to induce replication stress sensitized to the TNG348 and PARPi combination both in vitro and in vivo. These data indicate that cancer-specific elevated DNA replication stress could contribute to tumor sensitivity to TNG348 and provide additional patient stratification strategies and opportunities for indication expansion."

Characterization of the clinical development candidate TNG348 as a potent and selective inhibitor of USP1 for the treatment of BRCA1/2mut cancers
(AACR 2023)
- "Furthermore, TNG348 activity extends beyond BRCA1/2mut models with PARP inhibitor (PARPi) sensitivity and oncogene-induced replication stress being additional features correlating with USP1 inhibitor sensitivity based on cell line panel and CRISPR screening results. We show that TNG348 induces cell death through a pathway that is distinct from PARPi and TNG348 demonstrates robust synergy when combined with first- or second-generation PARPi. The clinical development plan intends to evaluate TNG348 in patients with BRCA1/2 mutations as single agent and in combination with PARP1i in patients naïve to PARPi and with prior PARPi treatment history."
