Clofarabine (Clolar)

Regimen #1, Faderl, et al. 2010

Initial dose was too toxic; 20 mg/m2 was final dose level

• Clofarabine (Clolar) 20 mg/m2 PO daily on days 1-5

4 to 8 week cycles x up to 12 cycles

Supportive medications:

• "Supportive care included anti-infectious prophylaxis (eg, levaquin, valacyclovir, and itraconazole or voriconazole), hematopoietic growth factors, and transfusions as judged indicated by the treating physician." In order to decrease risk of liver function abnormalities, no antifungals were given on the days where clofarabine was given.

Regimen #2, Faderl, et al. 2012

Lower dose was less toxic; clinical activity was comparable

• Clofarabine (Clolar) 15 mg/m2 or 30 mg/m2 IV over 1 hour daily on days 1-5

4 to 8 week cycles x up to 12 cycles

Supportive medications:

• "Supportive care measures such as antibiotic prophylaxis (eg, levofloxacin, valacyclovir, and itraconazole or voriconazole), hematopoietic growth factors, and transfusions were provided as necessitated for optimal medical care of the patients." In order to decrease risk of liver function abnormalities, no antifungals were given on the days where clofarabine was given.
