Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients must have radiologically confirmed (ie, CAT scan and/or MRI) persistent or recurrent EC of epithelial origin that has progressed after prior platinum based chemotherapy or is refractory to platinum-based chemotherapy.
  • Must have availability of archival tumor tissue FFPE block for TROP-2 testing
  • Note: The presence or absence of TROP-2 overexpression will NOT determine eligibility for study enrollment.
  • The diagnosis must be histologically confirmed by a gynecologic pathologist.
  • All patients must have measurable disease. Measurable disease is defined as lesions which can be measured by physical examination or by means of medical imaging techniques. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded). Each lesion must be ≥ 20 mm when measured by conventional techniques, including palpation or plain x-ray, or ≥ 10 mm when measured by spiral CT and/or MRI. Ascites and pleural effusions are not to be considered measurable disease.
  • Patients must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST v1.1. Tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence following completion of radiation therapy.

  • After undergoing surgery, patients may be optimally or sub optimally debulked.
  • Patients with measurable recurrent disease of any previous substage (I-IV) are eligible to enrollment.
  • Patients must have adequate bone marrow function: WBC greater than or equal to 3,000/ul, Platelets greater than or equal to 75,000/ul, Neutrophils greater than or equal to 1500/ul.
  • Patients must have adequate renal function: creatinine less than or equal to 2.0 mg/dL.
  • Patients must have adequate hepatic function: Bilirubin ≤ 1.5 X laboratory normal. SGOT/SGPT ≤ 3 X laboratory normal or ≤ 5 X laboratory normal if known liver metastases.
  • Patients must have an ECOG performance status of 0 or 1.
  • Patients must have signed an approved informed consent.
  • Patients must be at least 2 weeks beyond prior treatment (chemotherapy, investigational drugs including small molecular inhibitors, endocrine therapy, immunotherapy and/or radiation therapy) or major surgery.
  • Patients must be at least 2 weeks beyond high dose systemic corticosteroids (however, low dose corticosteroids ≤ 20 mg prednisone or equivalent daily are permitted).
  • Patients must have recovered from all acute toxicities to Grade 1 or less from adverse events due to a previously administered agent.
  • Note: Patients with ≤ Grade 2 neuropathy or ≤ Grade 2 alopecia are an exception to this criterion and may qualify for the study
  • Note: If patients received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
  • Patients with recurrent disease may have received multiple prior chemotherapies for treatment of their endometrial cancer.
  • Patients may have received prior immunotherapy therapy alone or in combination with chemotherapy.
  • Patients of childbearing potential must have a negative serum pregnancy test within 7 days prior to the study entry and be practicing an effective form of contraception during the study and until conclusion of 12-week post-treatment evaluation period.
  • Patients must be at least 18 years of age.

Who cannot join

  • Have an active second malignancy. Note: Patients with a history of malignancy that has been completely treated, with no evidence of active cancer for 3 years prior to enrollment, or subjects with surgically-cured tumors with low risk of recurrence are allowed to enroll.
  • Patients with a significant history of cardiac disease within 6 months, i.e., uncontrolled hypertension, unstable angina, uncontrolled congestive heart failure (NYHA classification III-IV) or clinically significant cardiac arrhythmia (other than stable atrial fibrillation) requiring antiarrhythmia therapy.
  • Patients with known history of clinically significant active COPD, or other moderate-to-severe chronic respiratory illness present within 6 months.
  • Patients with any unstable medical issue (including cardiac issues as above, active treatment for symptomatic pulmonary embolism, CVA, renal or hepatic insufficiency, and active infection/sepsis requiring IV antibiotics).
  • Have known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they have stable CNS disease for at least 4 weeks prior to the first dose of study drug and all neurologic symptoms have returned to baseline, have no evidence of new or enlarging brain metastases, and are taking ≤ 20 mg/day of prednisone or its equivalent. All patients with carcinomatous meningitis are excluded regardless of clinical stability.
  • Patients who have an uncontrolled seizure disorder, or active neurological disease.
Show all 14Show fewer
  • Have a known history of HIV-1/2 with uncontrolled viral load and on medications that may interfere with SN-38 metabolism.
  • Have active HBV or HCV. In subjects with a history of HBV or HCV, subjects with a detectable viral load will be excluded.
  • Known hemorrhagic diathesis or active bleeding disorder.
  • Patients with Gilbert's disease.
  • Patients with active ≥ grade 2 anorexia, nausea or vomiting, diarrhea, and/or signs of intestinal obstruction.
  • Prior history of clinically significant bleeding, intestinal obstruction, or GI perforation within 6 months of initiation of study treatment.
  • Patients with a history of an anaphylactic reaction to irinotecan or ≥ Grade 3 GI toxicity to prior irinotecan.
  • Patients who have previously received topoisomerase I inhibitors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate (ORR)

    Objective response rate (complete response and partial response rates) by RECIST1.1 criteria in patients with persistent or recurrent endometrial carcinoma (EC)

    Measured: 4 Years

Secondary outcomes (4)

  1. Duration of overall survival (OS)

    Overall survival is defined as the duration of time from study entry to death or the date of last contact.

    Measured: 6 Years

  2. Duration of progression free survival (PFS)

    Progression free survival is defined as the duration of time from study entry to time of progression, death, or is censored at date of last disease assessment

    Measured: 6 Years

  3. Durable disease control rate (DDCR)

    The percentage of patients who have achieved complete response, partial response, and stable disease

    Measured: 6 Years

  4. Assess the safety profile of sacituzumab govitecan in endometrial cancer patients (adverse events as assessed by CTCAE v5.0)

    Incidence of treatment-related adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v5.0

    Measured: 6 Years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sacituzumab Govitecan in people with Endometrial Carcinoma, run by Yale University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 11 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (ORR) (time frame: 4 Years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04251416.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2026; AzTrials last refreshed its copy on 8 Nov 2026.
