Overview

This is a **three-drug combination regimen** consisting of **iniparib** (formerly thought to be a PARP inhibitor, now recognized to have cytotoxic effects via an undefined mechanism), **pegylated liposomal doxorubicin** (a liposome-encapsulated formulation of the anthracycline doxorubicin, which intercalates DNA and inhibits topoisomerase II), and **carboplatin** (a platinum-based DNA-damaging chemotherapeutic agent). This combination was evaluated in clinical trials for the treatment of ovarian cancer, in particular for platinum-resistant or recurrent settings. While iniparib was originally believed to act as a PARP inhibitor, subsequent evidence indicates its mechanism is distinct and not canonical PARP inhibition. **Pegylated liposomal doxorubicin** is designed for improved pharmacokinetics and reduced cardiotoxicity compared to conventional doxorubicin. **Carboplatin** induces DNA cross-links, leading to apoptosis.
