For patients who stop study drug(s) because of a decrease in LVEF, LVEF should be assessed at least every 6 weeks to determine recovery/stabilization (until LVEF recovers to ≥ 50% or 2 years, whichever occurs first). In patients who required a repeat LVEF assessment to ensure an acceptable LVEF before continuing trastuzumab/pertuzumab treatment, an additional LVEF assessment is to be performed at the next treatment cycle. Note: approval of the Medical Monitor must be obtained before continuation of study treatment after delays > 21 days.",
