|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase 1/2 Therapeutic, Open Label, Multi-Center Clinical Trial of NPC-1C, a Chimeric Monoclonal Antibody, in Adults With Recurrent, Locally Advanced Unresectable or Metastatic Pancreatic and Colorectal Cancer After Standard Therapy|
- Efficacy will be assessed by analysis of CT scans pre and post therapy, clinical laboratory tests, and physical examinations. [ Time Frame: 10 weeks ] [ Designated as safety issue: No ]
- Efficacy OS [ Time Frame: 5 months ] [ Designated as safety issue: No ]Using the recommended phase 2 dose (RP2D) evaluate the overall survival (OS) associated with administration of NPC-1C (NEO-102) in subjects with metastatic, locally advanced unresectable or recurrent pancreatic cancer or metastatic colorectal cancer that express NPC-1C target on tumor.
- Safety will be assessed by analysis of adverse experiences, clinical laboratory tests, and physical examinations. [ Time Frame: 10 weeks ] [ Designated as safety issue: Yes ]
- Pharmacokinetics and select immune responses to the antibody will be assessed. [ Time Frame: 10 weeks ] [ Designated as safety issue: No ]
|Study Start Date:||January 2012|
|Estimated Study Completion Date:||April 2018|
|Estimated Primary Completion Date:||January 2018 (Final data collection date for primary outcome measure)|
Subjects will receive NPC-1C at a dose of 3.0 mg/kg. NPC-1C will be given intravenously (by vein) over approximately 1-6 hours, once every 2 weeks for 4 doses per course. Courses will be repeated in the absence of disease progression or unacceptable toxicity.

The limitations of many current therapeutic products for pancreatic cancer are widely recognized. Despite the development of several new treatment regimens for pancreatic cancer, little if any benefit has been appreciated, leaving this disease as one of the most significant unmet medical needs in cancer.
NPC-1C is a chimeric immunoglobulin molecule comprised from the variable region of the heavy chain and light chain of murine NPC-1, genetically engineered in-frame with the constant regions of a human IgG1 isotype. NPC-1, the predecessor of NPC-1C, was derived from a Tumor Associated Antigen (TAA) based vaccine that was previously tested in a Phase 1-2 clinical trial performed in the United States in the 1980's that explored the use of TAA therapy in patients with adenocarcinoma of the colon. These early studies demonstrated safety as well as preliminary evidence of activity in these patients treated with the vaccine.
NPC-1C antibody-staining studies demonstrate specific immunoreactivity with cancer tissues from colon and pancreas patients, whereas only weak binding, if at all, is observed in normal pancreas or colon tissues with no cross-reactivity observed in other normal human tissues. The Phase 2 portion of this trial is an open label, multi-center study estimated to treat approximately 30 patients with pancreatic cancer who have failed first line therapy, and 43 patients with metastatic colorectal cancer who are refractory to standard treatment.
