Study of DM5167 in Patients With Advanced Solid Tumors

An Open-label, Dose-finding, Phase 1 Study to Assess the Safety, Tolerability, Efficacy, and Pharmacokinetic Profile, and to Explore the Pharmacodynamic Profile of DM5167 in Patients With Advanced Solid Tumors

DM5167 is a second-generation of PARP inhibitor that selectively targets the PARP-1 enzyme. This results in less haematological toxicity and a high level of safety.

The aim of the study is to assess the safety and tolerability of DM5167 in patients with advanced solid tumors not respond to other treatments.

• Patients with life expectancy ≥ 12 weeks
• Patients who meet the clinical laboratory test criteria confirming adequate liver, renal, and hematologic function
• Patients who voluntarily provide written informed consent to participate in this study
• Patients with histologically or cytologically confirmed unresectable advanced solid tumors
• Patients who have BRCA1/BRCA2 mutations

Exclusion Criteria:

• Patients with a medical history of significant illness
• Patients with QT interval of > 450 ms (for men) or > 460 ms (for women)\
• Patients who have not yet recovered from toxicity related to previous anticancer therapy
