Clinical Trial Summary

The purpose of this research study is for the participant to give their own T cells (a type of blood cell in the body that can fight infections and possibly cancer) to them after they have been removed, grown in a lab, and then coated with an experimental drug.

This study will determine the highest dose of EGFR2Bi coated T cells that can be given without causing severe side effects. Initially a group of 3 participants will receive the same dose of study drug. If no serious side effects occur, the next group of participants will receive a slightly higher dose of study agent. The following groups of participants will receive higher doses of the study drug until a dose is reached where there are unacceptable side effects and maximum tolerated dose is found, or the planned highest dose level is reached with no side effects.

Description:

The purpose of this study is to determine in a dose-escalation phase Ib trial the safety of 3 infusions of EGFR2Bi armed activated T cells (aATC), after chemotherapy, for patients with advanced colorectal and pancreatic cancer

Intervention

Drug:
• FOLFOX6
IV administration of 85 mb/m(2) oxaliplatin and 400 mg/m(2) leucovorin over 120 mins, followed by 400 mg/m(2) 5-fluorouracil (FU) bolus then 2400 mg/m(2) 5-FU as a 46 hr infusion. All patients must have central intravenous acess (e.g. mediport, PICC line) for continuous infusion of 5-FU. Adv. colorectal and pancreatic pts. w/no other standard chemo available, & in pts who cannot receive FOLFOX chemo, immunotherapy may be given w/o antecedent chemo.

Biological:
• EGFRBi armed ATC Infusions
Armed ATC will be infused intravenously (IV) with the rate of infusion based on the endotoxin content of the product. All patients will be observed for at least 4 hours after an infusion. Armed ATC infusions will begin 3 weeks after chemotherapy and subsequent doses will be administered once weekly, for 3 weeks, then 12 weeks post aATC#1. Dose escalation level(per infusion): Level 0-5 billion; Level 1-10 billion; Level 2-20 billion; Level 3-40 billion

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Determining in a dose-escalation phase Ib trial the safety of 3 infusions of EGFR2Bi aATC, and a booster infusion after 3 months, for patients with advanced colorectal or pancreatic cancer.	Participants will be assessed for changes in lab values (CBC, Sodium, potassium, calcium, magnesium, chloride, bicarbonate, glucose,BUN, creatinine, total Protein, albumin, total bilirubin, ALP, AST,ALT, CEA or CA 19-9.	4 wks after chemo, prior to ATC infusion #2; 1 wk later prior to ATC infusion #3; Wks 2, 4 & 9 post ATC infusion #3; Wk 8 post ATC #4 (booster)
Secondary	Determining whether IMT enhances anti-tumor immunity;Cytokine resp., phenotypic markers, anti-tumor cytotoxicity, in vivo and in vitro specific anti-tumor antibody prod. & molecular signaling markers of T-cell activation assessed before chemo & after IMT	Immune studies: Serum cytokine responses will be quantified focus on the levels of those factors known to be important regulators of T cell responses. Phenotype analysis will measure the percent of T, B, NKT and NK cells in peripheral blood mononuclear cell (PBMC) and tumor-infiltrating lymphocyte (TIL) samples. T cell proportions would be further analyzed by subset (CD4, CD8, CD25+). Cytotoxicity is measured in percentage in PBMC.	3 weeks after chemo prior to ATC infusion #1; At wks 4(ATC #2) & 5 (ATC #3) post chemo; wks 2 , 4 & 9 post ATC #3 infusion; Day of ATC #4 (booster infusion), then wks 2, 4 & 8; & mon 6 and 1yr post ATC #4 (booster infusion)
Secondary	Determining the tumor response rate	CT or PET Scan	Approximately every 8 weeks to until 1 year
Secondary	Overall Survival	CT or PET Scan	Approximately every 8 weeks to until 1 year
