Subjects must meet all the following inclusion criteria to be eligible for enrolment into the study: 1. Histological/confirmed adenocarcinoma of the colon or rectum with metastatic disease not amenable to salvage surgery 2. Pathology mandatory requirements: a. the original tumour specimen must be KRAS WT and HER2 IHC 3+ positive, with = 50% positive cells. This criterium is pending confirmation from the ongoing HERACLES DGX validation study. b. the original paraffin block or a minimum of 15 polarized unstained slides from the original paraffin block must be made available to the Pathology Core within 15 days from registration. 3. Age =18 4. ECOG PS 0-1 5. Measurable disease as defined by RECIST 1.1 criteria 6. Progression (PD) while on treatment, or within 6 months from therapy with approved standard drugs 7. Unless otherwise contraindicated patients should have received and failed the following previous therapies for mCRC: fluoropirimidines, oxaliplatin, irinotecan, cetuximab or panitumumab containing regimens. Bevacizumab is allowed 8. Adequate haematological function as defined by: ANC ? 1.5 x 109/L, platelet count ?100 x 109/L, haemoglobin ? 10 g/dL. 9. Adequate renal function, as defined by: creatinine ? 1.5 x UNL 10. Adequate hepatobiliary function, as defined by the following baseline liver function tests: o total serum bilirubin ?1.5 upper normal limit (UNL) o alanine aminotransferase (ALT), aspartate aminotransferase (AST) ? 2.5xUNL o alkaline phosphatase (AP) ? 2.5xUNL; if total alkaline phosphatase (AP) > 2.5xUNL, alkaline phosphatase liver fraction must be ? 2.5xUNL 11. Adequate contraception for all fertile patients 12. Negative pregnancy test.

- Primary Outcome Measures
Name Time Method Main Objective: Define the antitumor activity of the anti-HER2 combinations of lapatinib + trastuzumab and pertuzumab + trastuzumab given to two separate, sequential cohorts of patients with chemo-refractory advanced disease and HER2 amplified tumours.;Secondary Objective: 1. Define the safety profile of the two combinations 2. Define the Progression Free Survival (PFS);Primary end point(s): Objective Response Rate according to RECIST 1.1 criteria;Timepoint(s) of evaluation of this end point: Tumor response will be assessed starting on week 8 and every 8 weeks thereafter. Tumor response MUST be confirmed 4 + 1week from first assessment of response.
- Secondary Outcome Measures
Name Time Method Secondary end point(s): 1. Description of the frequency and severity of Adverse Events based on the NCI –CTCAE V4.0 2. PFS 3. Correlation between selected tumor biomarkers evaluated in tumor specimens (including but not limited to mutations of effectors downstream of HER-family receptors - such as KRAS, BRAF, and PIK3CA, or related tyrosine kinase receptors), and tumor response/resistance to experimental treatment 2. Comparison of tumor biomarkers status in blood samples collected before start of treatment, with that collected during treatment and after progression;Timepoint(s) of evaluation of this end point: Throughout the study
