Inclusion Criteria

- Histologically confirmed breast carcinoma with clinical diagnosis of IBC

Cohort A - overexpresses ErbB2 (defined IHC 2+ or 3+, or FISH-positive) with or without expression of ErbB1 (by IHC), or
Cohort B - expression of ErbB1 (defined as IHC +) without overexpression of ErbB2.
ErbB1 and ErbB2 status must be documented prior to dosing.

- ECOG performance status 0-2
- Have adequate bone marrow function, and renal and hepatic function
- Have left ventricular ejection fraction greater than or equal to 50% based on ECHO or MUGA scan

Primary Outcome Measures
NameTimeMethod
Main Objective: Evaluation of pathologic response rate following 14 days of neoadjuvant daily treatment with lapatinib monotherapy, followed by 12 weeks of daily lapatinib in combination with weekly-administered paclitaxel, in patients with treatment-naive IBC whose tumours overexpress ErbB2 +/- ErbB1 receptor(s) (Cohort A) and in patients whose tumours express the ErbB1 receptor but do not overexpress ErbB2 (Cohort B).;Secondary Objective: - To assess objective response rate following 14 days of lapatinib monotherapy and 12 weeks of lapatinib combined with weekly-administered paclitaxel<br>- Assess safety and tolerability of once-daily lapatinib with weekly paclitaxel<br>- Investigate pharmacodynamic effects of study treatment on intracellular biomarkers<br>- Assess the effects of study treatment on proteomic profile and blood levels of extracellular domains of the ErbB1 and ErbB2 receptors<br>- Pharmacogenetic investigation/s;Primary end point(s): Determination of complete pathologic response rate (pCR)
