This is an open-label safety and tolerability study in which approximately 600 subjects will
receive NKTR-181 for up to 52 weeks. Subjects may include newly enrolled subjects and
subjects who have recently completed SUMMIT-07 or SUMMIT-12 studies.

This study will also investigate the pharmacokinetics of NKTR-181 in patients with chronic
low back pain or chronic non-cancer pain.
