Dose-escalation Study of Quarfloxin in Patients With Advanced Solid Tumors or Lymphomas
- Registration Number
- NCT00955292
- Lead Sponsor
- Cylene Pharmaceuticals
- Brief Summary
This phase 1 study of quarfloxin (CX-3543) is designed to test the safety, tolerability, and highest safe dose of this drug when administered intravenously weekly for three weeks of a four week cycle in patients with advanced solid tumors.
- Detailed Description
Quarfloxin is a first-in-class small-molecule targeted cancer therapeutic derived from the validated fluoroquinolone class of drugs. Quarfloxin was rationally designed to target a G-quadruplex (QPLX) DNA structure and disrupt protein-DNA interactions essential to cancer cells. The QPLX targeted by quarfloxin forms within ribosomal DNA (rDNA) and the QPLX is bound by the nucleolin protein.
