A Phase I/IIa, Open-label, Multi-center Study to Assess the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of the DNA Polymerase Theta Inhibitor ART6043 Administered Orally as Monotherapy and in Combination to Patients With Advanced or Metastatic Solid Tumors

ART6043 is being developed as an oral anti-cancer agent in combination with a poly (adenosine diphosphate ribose) polymerase (PARP) inhibitor (PARPi) in patients with cancers that harbor defects in DNA repair. The study will consist of two parts: 1. Part A (Dose-escalation phase): Part A will evaluate ART6043 as monotherapy (Part A1) in patients with advanced or metastatic cancer and in combination with olaparib (Part A2), in patients with advanced or metastatic cancer with genetic lesions that cause loss of function of known DNA Damage Response (DDR) genes. Olaparib is also referred as PARP…
