A phase 1 open-label trial evaluating M4076 in patients with advanced solid tumors (DDRiver™ Solid Tumors 410)1

ClinicalTrials.gov: NCT04882917

Location: North America



M4076 is an investigational orally administered ATP-competitive inhibitor of ataxia telangiectasia mutated (ATM) protein kinase, a key component of the DNA damage response (DDR) pathway. In preclinical studies, M4076 demonstrated subnanomolar potency and selectivity for ATM1-3


Key inclusion criteriaa

  • Advanced solid tumors, for which standard-of-care therapy does not exist or is considered insufficiently effective, or no tolerance of standard of care

  • ECOG PS of ≤1

  • Paired tumor biopsies (if not contraindicated) for part 1B

Key exclusion criteriaa

  • Clinically significant uncontrolled intercurrent illness

  • Ataxia telangiectasia

  • ATM mutations

Study design | North America


M4076 is being investigated in this clinical trial. This means that it has not been shown to be safe or effective for any purpose or disease. This page describes one of the clinical trials for M4076, and it includes information about how the safety and efficacy of M4076 will be measured and evaluated. Therefore, it is important to understand that M4076 is not a treatment or therapy for cancer or any other disease, its use has not been approved by any health authority, such as the European Medicines Agency or the US Food and Drug Administration, and there is no guarantee that M4076 will be approved in the sought-after indication by any health authority worldwide.
