A Ph 2 Study of Fosbretabulin in Subjects w Pancreatic or Gastrointestinal Neuroendocrine Tumors w Elevated Biomarkers
Trial ID or NCT#
Status
Purpose
This study will investigate the safety, symptoms and biomarker response of subjects with biopsy-proven well-differentiated, low-to-intermediate-grade, unresectable, or metastatic pancreatic neuroendocrine tumors (PNETs) or or Gastrointestinal Neuroendocrine tumors (GI-NETs) with elevated biochemical markers who have relapsed during or after receiving prior standard of care therapies, including octreotide, chemotherapy or targeted therapy.
Official Title
A Ph 2 Study to Investigate the Safety and Activity of Fosbretabulin Tromethamine (CA4P) in the Treatment of Well-Differentiated, Low-to-Intermediate-Grade Unresectable, Recurrent or Metastatic PNET or GI-NET Neuroendocrine Tumors/Carcinoid With Elevated Biomarkers
Eligibility Criteria
- * Ability to read, understand and provide written consent to participate in the study* Age ≥ 18 years* Biopsy-proven well-differentiated, low-to-intermediate-grade PNET or GI-NET with elevated (\> ULN) biomarkers (serotonin, 5-hydroxyindoleacetic acid (5-HIAA), chromogranin A (CgA), neurokinin A, and neuron-specific enolase (NSE))* Life expectancy \> 12 weeks* Must have received or may still be receiving one or more therapies including octreotide or serotonin synthesis inhibitor (SSI) or other somatostatin analogues* Confirmed progressive disease within 18 months of enrollment on study* Recovered from prior radiation therapy or surgery* Eastern Cooperative Oncology Group (ECOG) performance score 0-2* Absolute neutrophil count (ANC) ≥ 1,500/µL (without growth factors)* Platelet count ≥ 100,000/µL* Adequate renal function as evidenced by serum creatinine
- ≤ 2.0 mg/dL (177 µmol/L)* Adequate hepatic function: serum total bilirubin ≤ 2X greater than the upper limit of normal (ULN) (≤ 3X ULN in subjects with liver metastases), aspartate aminotransferase) AST) / alanine aminotransferase (AST) ≤ 2X the ULN for the local reference lab (≤ 5X the ULN for subjects with liver metastases)* Disease that can be assessed (evaluable) with imaging (CT, MRI, PET, radionuclide imaging or other imaging modality)* Women of childbearing potential as well as fertile men and their partners must use an effective method of birth control
- * Inadequately controlled hypertension defined as BP \> 150/100 mm Hg despite medication* Prior history of hypertensive crisis or hypertensive encephalopathy* Recent history (within 6 months of start of screening) of unstable angina pectoris pattern, myocardial infarction (including non-Q wave MI), or NYHA (New York Heart Association) Class III and IV Congestive Heart Failure (CHF)* Subjects who have clinical evidence of carcinoid-induced heart disease* History of prior cerebrovascular accident (CVA), including transient ischemic attach (TIA)* Known central nervous system (CNS) disease except for treated brain metastasis* History of torsade de pointes, ventricular tachycardia or fibrillation, pathologic sinus bradycardia (\<60 bpm), heart block (excluding 1st degree block, being PR interval prolongation only), congenital long QT syndrome or new ST segment elevation or depression or new Q wave on ECG* Corrected QT interval (QTc) \> 480 msec* Ongoing treatment with any drugs known to prolong the QTc interval, including anti-arrhythmic medications (stable regimen of antidepressants of the selective serotonin reuptake inhibitor (SSRI) class is allowed))* Evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation)* Significant vascular disease or recent peripheral arterial thrombosis* Known intolerance of or hypersensitivity to fosbretabulin* History of solid organ transplant or bone marrow transplant* Any other intercurrent medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with a subject's ability to sign informed consent, cooperate and participate in the study, or interfere with the interpretation of the results* High grade or poorly differentiated NET* NET tumor other than PNET or GI-NET* No elevated biomarker (\>ULN) that can be followed* Received regional hepatic infusion therapy within 6 months of enrollment (RFA allowed \>6 months prior to enrollment)
