Pentostatin (Nipent)
back to top |
Regimen #1
Study | Evidence |
Cassileth et al. 1991 | Phase II |
- Pentostatin (Nipent) 5 mg/m2 IV over 2 minutes once per day on days 1 & 2
14-day cycles, continued to the point of maximal response or treatment failure
Regimen #2, Grever et al. 1995 & Flinn et al. 2000
Phase III
- Pentostatin (Nipent) 4 mg/m2 IV rapid injection once on day 1
- Grever et al. 1995: Patients with performance status of 3 received an initial dose of Pentostatin (Nipent) 2 mg/m2 IV rapid injection once on day 1, which would be increased in later cycles to Pentostatin (Nipent) 4 mg/m2 IV rapid injection once on day 1 if patients had no adverse reactions.
- Grever et al. 1995: Doses of pentostatin were held for patients who had an increase in the serum creatinine concentration >20% above their baseline. Pentostatin was not given until renal function returned to baseline or if 24-hour creatinine clearance was >50 mL/min.
Supportive medications (per Grever et al. 1995):
- 1.5 liters of IV fluid hydration with every dose of pentostatin
14 day cycles; patients who had complete response before 6 months were given 2 additional cycles of pentostatin, and then treatment was stopped. Patients with objective partial response after 6 months of treatment received an additional 6 months of additional therapy, until they had a complete response or progression of disease.
