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.
Advanced Solid Tumors
Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Phase I, Multicenter, Open-label, Dose-Escalation, Safety, Pharmacokinetic and Pharmacodynamic Study of Quarfloxin Administered Intravenously Weekly for Three Weeks of a Four Week Cycle in Patients With Advanced Solid Tumors or Lymphomas
Primary Outcome Measures:
- Maximum tolerated dose (MTD) and Dose limiting toxicity (DLT) [ Time Frame: Cycle 1 ] [ Designated as safety issue: Yes ]
- Recommended Phase 2 dose [ Time Frame: Cycle 1 ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Pharmacokinetics (PK) in humans of intravenously administered quarfloxin [ Time Frame: One month ] [ Designated as safety issue: No ]
- Evaluation of antitumor activity of quarfloxin by objective radiologic assessment [ Time Frame: Every 2 months ] [ Designated as safety issue: No ]
- Pharmacodynamic evaluation of antitumor activity [ Time Frame: Monthly ] [ Designated as safety issue: No ]

Escalating doses of quarfloxin administered intravenously for 24 hours once weekly for three weeks every four weeks
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.
