Evaluation of MM-151 + Nal-IRI + 5-FU + Leucovorin in RAS/RAF Wild-type Metastatic Colorectal Cancer

Study Overview
=================
Brief Summary
-----------------
A phase 1b/2a study evaluating the combination of MM-151 + nal-IRI + 5-FU + Leucovorin in RAS/RAF wild-type Metastatic Colorectal Cancer.

Detailed Description
-----------------
Part 1: Patients will be enrolled to determine the maximum tolerated dose, safety and tolerability of MM-151 + nal-IRI + 5-FU + LV in patients with mCRC that are RAS/RAF wild-type. Part 2: Patients will be enrolled at the maximum tolerated dose of MM-151 in combination with nal-IRI + 5-FU + LV to characterize initial efficacy in conjunction with levels of irinotecan and SN-38 measured in tissue.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To find the phase II dose of MM-151 based on safety and tolerability of MM-151 + nal-IRI + 5-FU + Leucovorin that will be assessed through evaluation of dose limiting toxicity reporting. |  | The DLT timeframe is from date of first dose up until 42 days after that date | 
| To correlate disease response according to RECIST with levels of irinotecan and SN-38 in tumor tissue |  | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The number of participants with adverse events (AE) related to treatment with MM-151 + nal-IRI + 5-FU + leucovorin, assessed according to NCI CTCAE v4.0 | These will be described by abnormalities in hematology, blood chemistry and other laboratory abnormalities, ECG, physical examination, vital signs and other safety parameters. Frequency, duration and severity of the adverse events according to NCI CTCAE v4.0 will be assessed. | 2 years | 
| The PK parameters of MM-151 and nal-IRI will be described per Cmax |  | Priming Phase Day 1, Priming Phase Day 8, C1D1, C1D8, C1D15, C1D22, C2D1, C2D15, C2D17, C2D22, C3D1, C5D1 | 
| The PK parameters of MM-151 and nal-IRI will be described per AUC |  | Priming Phase Day 1, Priming Phase Day 8, C1D1, C1D8, C1D15, C1D22, C2D1, C2D15, C2D17, C2D22, C3D1, C5D1 | 
| Objective response based on RECIST |  | 2 years | 
| Measure pre-treatment and on-treatment levels of EGFR ligands |  | 2 years | 
| Presence of anti-drug antibodies will be assessed |  | 2 years |
