PHASE3

Testing the Addition of Herceptin Hylecta or Phesgo to the Usual Chemotherapy for HER2 Positive Endometrial Serous Carcinoma or Carcinosarcoma

Sponsor: National Cancer Institute (NCI)

View on ClinicalTrials.gov

Summary

This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta \[TM\]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo \[TM\]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab or pertuzumab attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Hyaluronidase is an endoglycosidase. It helps to keep pertuzumab and trastuzumab in the body longer, so that these medications will have a greater effect. Hyaluronidase also allows trastuzumab and trastuzumab/pertuzumab to be given by injection under the skin and shortens their administration time compared to trastuzumab or pertuzumab alone. Paclitaxel is a taxane and in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Giving Herceptin Hylecta or Phesgo in combination with paclitaxel and carboplatin may shrink the tumor and prevent the cancer from coming back in patients with HER2 positive endometrial cancer.

Official title: 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

Inclusion Criteria: * Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA-IVB, non-recurrent, chemotherapy (chemo)-naive, HER2-positive endometrial cancer. The following endometrial cancer types are eligible: * Serous * Other endometrial cancers (including clear cell, endometrioid, mixed epithelial, dedifferentiated/undifferentiated) * Carcinosarcoma * NOTE: Endometrial cancers that are mismatch repair deficient (dMMR) by IHC are not eligible * Histologic confirmation of the original primary tumor is required. Submission of surgical pathology report (or endometrial biopsy pathology report in patients who never undergo hysterectomy) is required * Patients must be within 8 weeks of primary surgery (or endometrial biopsy in patients who never undergo hysterectomy) at the time of study registration * Patients may have measurable disease, non-measurable disease, or no measurable disease. In patients with measurable disease, lesions will be defined and monitored by RECIST v 1.1. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be \>= 10 mm when measured by CT or magnetic resonance imaging (MRI). Lymph nodes must be \>= 15 mm in short axis when measured by CT or MRI * For patients with uterine-confined (stage I) disease, the tumor must be invasive into the myometrium. Any amount of myoinvasion is acceptable for eligibility. Patients with non-invasive disease, endometrial intraepithelial carcinoma alone, or disease confined to a polyp will be excluded * All patients must have tumors that are HER2 positive as defined by American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) 2018 Breast Cancer guidelines. IHC and ISH testing will be done locally, at each participating institution and interpreted by local pathologists. In general HER2 positivity is defined as any of the following: * 3+ immunohistochemistry (IHC), * 2+ IHC with positive in situ hybridization (ISH) Alternatively, patients could be eligible if next generation sequencing (NGS) demonstrates HER2 (ERBB2) amplification. NGS testing can be performed through any designated labs as per the National Cancer Institute (NCI) MATCH/NCI Combo-MATCH trial. Pathology report showing results of institutional HER2 testing (or NGS testing results) must be submitted. Sites must submit all results available (IHC, ISH, and NGS) * Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2 * Age \>= 18 * Platelets \>= 100,000/mcl (within 14 days prior to registration) * Absolute neutrophil count (ANC) \>= 1,500/mcl (within 14 days prior to registration) * Creatinine =\< 1.5 x institutional/laboratory upper limit of normal (ULN) or estimated Glomerular filtration rate (eGFR) \>= 50 mL/min using either the Cockcroft-Gault equation, the Modification of Diet in Renal Disease Study, or as reported in the comprehensive metabolic panel/basic metabolic panel (eGFR) (within 14 days prior to registration) * Total serum bilirubin level =\< 1.5 x ULN (patients with known Gilbert's disease who have bilirubin level =\< 3 x ULN may be enrolled) (within 14 days prior to registration) * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =\< 3 x ULN (within 14 days prior to registration) * Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of registration are eligible for this trial * Although the uterus will have been removed in the vast majority of patients, for patients of child-bearing potential: negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required. Patients will be considered of non-reproductive potential if they are either: * Postmenopausal (defined as at least 12 months with no menses without an alternative medical cause; in women \< 45 years of age, a high follicle stimulating hormone \[FSH\] level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, a single FSH measurement is insufficient); OR * Have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation/occlusion at least 6 weeks prior to registration * Have a congenital or acquired condition that prevents childbearing * Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial * Patients with evidence of chronic hepatitis B virus (HBV) infection must have an undetectable HBV viral load on suppressive therapy, if indicated * Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured.
