A Phase II/III Study of Paclitaxel/Carboplatin Alone or Combined with Either Trastuzumab and Hyaluronidase-Oysk (Herceptin Hylecta) or Pertuzumab, Trastuzumab, and Hyaluronidase-Zzxf (Phesgo) in Her2 Positive, Stage I-IV Endometrial Serous Carcinoma or Carcinosarcoma
This phase II/III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin HylectaTM) or pertuzumab, trastuzumab and hyaluronidase-zzxf (PhesgoTM) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial serous carcinoma or carcinosarcoma.
