Infusional VCR in humans(Jackson et al; Cancer 53:2601-2606, 1984) • 25 pts with a variety of NHL • 5-day continuous IV VCR 0.25 mg/m2/day after initial 0.5 mg I.V. bolus • Repeat course q 3 wks EB-802
Infusional VCR in Humans - Safety • Principal complication = mild to mod neurotoxicity (48%) • GI toxicity included severe ileus • Hematological toxicity was minimal EB-803
Dr. Jackson’s Comments onClinical Results for VSLI • Ability to deliver such high cumulative dose of vincristine with low GI toxicity and no ileus is highly unusual • Ability to proceed to transplant following monotherapy is also highly unusual EB-804
