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.

Criteria
Inclusion Criteria:

- Patients must have central IV access, or agree to the insertion of a central IV line.
- Normal oxygen saturation by pulse oximetry on room air
- A negative pregnancy test (if female).
- Acceptable liver function as evaluated by laboratory results
- Acceptable renal function as evaluated by laboratory results
- Acceptable hematologic status as evaluated by laboratory results
- No clinically significant urinalysis abnormalities
- Acceptable coagulation status as evaluated by laboratory results
- Fertile men and women must use effective contraceptive methods during the study.
Exclusion Criteria:
- Seizure disorders requiring anticonvulsant therapy.
- Known brain metastases (unless previously treated and well controlled for a period of greater than or equal to 3 months).
