Addition of Trastuzumab or Trastuzumab/​Pertuzumab to the Usual Chemotherapy for HER2 Positive Endometrial Cancer

This phase II/III trial investigates if adding HerceptinHylecta™ (trastuzumab and hyaluronidase-oysk) or Phesgo™ (pertuzumab,trastuzumab, and hyaluronidase-zzxf) to standard chemotherapy (paclitaxel andcarboplatin) can help shrink tumors in patients with HER2 positive endometrialserous carcinoma or carcinosarcoma.

  • Herceptin Hylecta™ (trastuzumab and hyaluronidase-oysk)
  • Phesgo™(pertuzumab, trastuzumab, and hyaluronidase-zzxf)
  • standardchemotherapy (paclitaxel and carboplatin)
  • Trastuzumab and pertuzumab aretypes of targeted therapy that block growth signals from reaching cancer cellsby attaching to HER2 receptors on their surface.
  • Hyaluronidase helps these drugsstay in the body longer and allows for quicker, under-the-skin injections.
  • Paclitaxel and carboplatin arechemotherapy drugs that kill or stop cancer cells from dividing.
  • This combination couldpotentially reduce tumor size and prevent cancer recurrence.
  • Phase II: To test how effective the combination of HERCEPTIN HYLECTA (trastuzumab and hyaluronidase-oysk) and PHESGO (pertuzumab, trastuzumab, and hyaluronidase-zzxf) with paclitaxel and carboplatin is in treating patients with HER2 positive endometrial serous carcinoma or carcinosarcoma.
  • Phase III: To further evaluate the effectiveness of the same treatment combination in a larger group of patients with the same conditions.

This clinical study is for patients who have a type of uterine cancer that has not been treated with chemotherapy before. Here's what patients need to know to participate:

Cancer Type: The study is open to patients with HER2-positive endometrial serous carcinoma or carcinosarcoma.

Cancer Stage: Patients with any stage from the earliest (stage IA) to the most advanced (stage IVB) can join, provided their cancer has not come back after initial treatment.

Surgery Requirements: Patients must have had surgery for their cancer within the last 8 weeks. If they didn’t have a hysterectomy, a biopsy confirming cancer is required.

Disease Measurement: The study includes patients whether their disease can be measured by scans or not. For those with measurable disease, specific criteria based on scan results are used to define it.

Eligibility Criteria: The study includes patients whether their disease can be measured by scans or not. For those with measurable disease, specific criteria based on scan results are used to define it.

Eligibility Criteria: 

  • Patients must show invasive cancer growth into the muscle layer of the uterus.
  • Cancer should be confirmed as HER2-positive by tests outlined in the 2018 guidelines.
  • Patients need to be healthy enough for chemotherapy (with certain blood count and organ function levels within required ranges).
  • Patients with HIV must have an undetectable viral load.
  • Women of childbearing potential must have a negative pregnancy test.
  • Individuals with other types of cancer or certain medical conditions may still be eligible.

Participants will also need to provide a consent form before joining the study.

For this clinical study, there are certain conditions that would prevent someone from participating:

Prior Cancer Treatment: You cannot join if you've had chemotherapy, biological therapy, or targeted therapy for endometrial cancer before. Also, you shouldn’t have had radiation therapy for endometrial cancer, except for vaginal brachytherapy, which is allowed during the study.

Hormonal Therapy: If you’ve received hormonal therapy for endometrial cancer, you must stop it at least one week before joining the study.

Upcoming Surgeries or Radiation: You cannot plan to have major surgery (like a hysterectomy) or external beam radiation therapy until the cancer shows signs of progression after joining the study.

Heart Conditions: You can't join if you have uncontrolled high blood pressure, recent heart attacks or severe heart disease, or serious heart rhythm problems.

Lung Conditions: If you have severe lung disease, including difficulty breathing at rest, severe pneumonitis, or other serious lung conditions, you cannot participate.

Other Health Issues: Uncontrolled infections, severe congestive heart failure, or any serious mental health or social situations that could affect your ability to follow the study rules are also reasons you might not be able to join.

Medications: If you’ve been treated with certain strong medications that affect liver enzymes within two weeks before joining the study, you may need to wait longer.

Nursing Women: If you are nursing and unwilling to stop, you cannot participate in the study.
