Statement: the primary trial and the secondary trial both have a control arm, and several test arms.
Primary_evidence: INTERVENTION 1:    Zr89-trastuzumab PET/CT   Zr89-trastuzumab (trastuzumab labelled with zirconium 89) for PET/CT single arm
Secondary_evidence: INTERVENTION 1:    Trastuzumab/Ixabepilone/Carboplatin   During the induction phase, patients were treated with Ixabepilone (BMS-247550) 15mg/m2 intravenously (IV) followed by carboplatin (AUC=2 IV) on days 1, 8 and 15 of a 28-day cycle for a maximum of 6 cycles. Trastuzumab was administered weekly (4mg/kg loading dose then 2mg/kg IV) starting on day 1. Routine premedication included H1 blocker (diphenhydramine 50 mg orally (PO) or IV), H2 blocker (ranitidine 150 mg PO or 50 mg IV or another equivalent H2 blocker), and at least a 5-HT3 antagonist and dexamethasone.   After completion of 24 weekly trastuzumab doses (induction therapy), trastuzumab were given at a dose of 6 mg/kg IV every 3 weeks (maintenance therapy) beginning one week after the 24th weekly dose. Trastuzumab were repeated every 21 days until disease progression or prohibitive toxicity.
