Phase I/Randomized Phase II Study of Second Line Therapy With Irinotecan + Cetuximab +/- RAD001 for Colorectal Cancer

• To determine the MTD of RAD001 in combination with irinotecan and cetuximab as second line therapy in patients with metastatic colorectal cancer [ Time Frame: Phase I ] [ Designated as safety issue: Yes ]
  
• To evaluate the objective response (CR or PR) rates of patients treated with irinotecan and cetuximab with or without RAD001 in patients with metastatic colorectal cancer [ Time Frame: Phase II ] [ Designated as safety issue: No ]
  

• To evaluate the pharmacokinetic (PK) profile for RAD001 after one cycle of therapy, on cycle 2 day 1 [ Time Frame: Phase I ] [ Designated as safety issue: No ]
  
• To evaluate the time to progression, duration of objective response (CR or PR) and overall survival of patients treated with irinotecan and cetuximab with or without RAD001 [ Time Frame: Phase II ] [ Designated as safety issue: No ]
  

OUTLINE: This is a multi-center study.

PHASE I:

• UGT1A1 *28 7/7 genotype IS NOT present
• Cetuximab 250 mg/m2 IV days 1, 8, and 15
• Irinotecan 125 mg/m2 IV days 1 and 8
• RAD001 PO QD (dose determined at the time of registration; subjects will remain at this dose level until treatment discontinuation)

PHASE II:

• Randomization based on UGT1A1 *28 7/7 Genotype or Prior Irinotecan Exposure

ARM A:

• Cetuximab 250 mg/m2 IV days 1, 8, and 15
• Irinotecan 125 mg/m2 IV days 1 and 8

AT TIME OF PROGRESSIVE DISEASE, ARM A TREATMENT WILL CROSSOVER:

• Cetuximab 250 mg/m2 IV days 1, 8, and 15
• Irinotecan 125 mg/m2 IV days 1 and 8
• RAD001 PO QD (maximum tolerated dose)

ARM B:

• Cetuximab 250 mg/m2 IV days 1, 8, and 15
• Irinotecan 125 mg/m2 IV days 1 and 8
• RAD001 PO QD (maximum tolerated dose)

AT TIME OF PROGRESSIVE DISEASE, ARM B TREATMENT WILL BE DISCONTINUED
