Overview

CRLX101 + paclitaxel is a combination investigational therapy targeting cancer. CRLX101 is a nanopharmaceutical comprised of camptothecin (CPT) conjugated to a cyclodextrin-based polymer, forming nanoparticles that deliver CPT directly into tumors. It acts primarily as a topoisomerase I inhibitor and can also inhibit HIF-1α (hypoxia-inducible factor-1 alpha). Paclitaxel is a microtubule-stabilizing agent that inhibits cell division by preventing microtubule depolymerization. The combination aims to improve anti-tumor efficacy through synergistic mechanisms: paclitaxel's cytotoxic activity and CRLX101's capability for sustained, tumor-targeted delivery of camptothecin. This regimen has been investigated in clinical trials for recurrent or persistent epithelial ovarian, fallopian tube, or primary peritoneal cancer and other tumor types. Preclinical data suggest possible antiangiogenic effects and synergistic activity[1][3][5].
