About

This clinical trial is evaluating a drug called ART0380 in participants with advanced or metastatic solid tumors. The main goals of this study are to: Find the recommended dose of ART0380 that can be given safely to participants alone and in combination with gemcitabine or irinotecan Learn more about the side effects of ART0380 alone and in combination with gemcitabine or irinotecan Learn more about the effectiveness of ART0380 alone and in combination with gemcitabine or irinotecan

Full description

ART0380 is a new investigational medicinal product that is a potent and selective inhibitor of Ataxia telangiectasia and Rad3-related (ATR). ART0380 is being developed as an oral anti-cancer agent for the treatment of participants with cancers that harbor defects in deoxyribonucleic acid (DNA) repair and in combination with agents including those that cause DNA damage. This study is an open-label Phase I/IIa study designed to evaluate the safety, tolerability, PK and preliminary efficacy of ART0380 as monotherapy or in combination with gemcitabine or irinotecan in participants with advanced or metastatic solid tumors, advanced or solid tumors that fail to express Ataxia-Telangiectasia Mutated protein kinase (ATM) by immunohistochemistry, and high grade serous ovarian, primary peritoneal or fallopian tube carcinoma.

Additional inclusion criteria for participants in dose expansion (Part B2):

  • Patients with a known germline BRCA mutation, or a cancer with a known somatic BRCA mutation, or which is known to be HRD positive, and for which there is an approved PARP inhibitor should have received such treatment before participating in the study, unless contra-indicated.
  • Females with histologically-confirmed diagnosis of high grade serous carcinoma of the ovary, fallopian tube or primary peritoneum that is not amenable to curative therapy
  • Platinum-resistant disease, defined as disease progression within 6 months of last receipt of platinum-based chemotherapy. Patients must not have had primary platinum-refractory disease (disease that progressed during first-line platinum-based therapy).
  • No more than one prior regimen in the platinum-resistant setting. Hormonal therapies and antiangiogenic therapies (as single agents) and PARP inhibitors used as maintenance therapy are not considered as separate lines of therapy. Patients should have previously received bevacizumab and chemotherapy unless contra-indicated.
  • Have not received prior treatment with gemcitabine unless administered in combination with a platinum with no disease progression within 12 months after completion of that regimen
  • Have at least 1 measurable lesion assessable using standard techniques by RECIST v1.1
  • Performance status of 0-1 on the on the ECOG scale

Inclusion criteria specific to Part B3
