Brief Summary:
Subjects achieving a clinical response in study OX4218s with a biomarker reduction or symptom response are eligible to enroll in this rollover study to continue once every three weeks fosbretabulin infusions for up to one year.

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Drug: fosbretabulin Phase 2

Detailed Description:
Subjects enrolled in the PNET/GI-NET study OX4218s received weekly dosing with fosbretabulin for up to 3 cycles or approximately 9 weeks. Subjects achieving a clinical response with a biomarker reduction or symptom response based on investigator assessment are eligible to enroll in this rollover study (protocol OX4219s). Subjects will receive fosbretabulin every three weeks for a maximum of approximately one year or until disease progression, unacceptable toxicity, consent withdrawal, protocol-noncompliance, or the investigator feels that it is no longer in the subject's best interest to continue therapy.
