NKTR 102 (Pegylate Irinotecan) RECIST responses (confirmed and unconfirmed) were 27% and 22% for the q14d and q21d schedules.
One dose level 145mg/m2.

Irinotecan with a half life of 30-40 hours vs NKTR 102 with a half life of 50+ days.

The patient can back off the dose scheduling from 2 weeks to three weeks and still response to NKTR 102.
