Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - ATX-101 + Carboplatin + Pegylated liposomal doxorubicin (ACD)

Experimental: Part 1 - ACD (Safety) - ATX-101 plus carboplatin and pegylated liposomal doxorubicin (ACD)

Experimental: Part 2 - ACD (Efficacy) - ATX-101 plus carboplatin and pegylated liposomal doxorubicin (ACD)


Treatment: Drugs: ATX-101 + Carboplatin + Pegylated liposomal doxorubicin (ACD)
Pegylated liposomal doxorubicin (30 mg/m²) will be administered intravenously on Day 1 of each 28-day cycle; carboplatin (AUC5) will be administered intravenously on Day 1 of each cycle.

ATX-101 will be administered intravenously on Day 2 of each cycle in three escalation cohorts: 20, 30, and 45 mg/m² according to a 3+3 design.
