This is a non-randomized Phase 2 study of sacituzumab govitecan (IMMU-132) in subjects with persistent or recurrent endometrial carcinoma.

Detailed Description

      This is an open-label, Phase 2 study designed to assess the clinical activity of sacituzumab
      govitecan in subjects with persistent or recurrent endometrial carcinoma with elevated Trop-2

Trial Arms

Sacituzumab GovitecanExperimentalSacituzumab govitecan will be administered at 10 mg/kg weekly as an infusion for 2 consecutive weeks (2 weekly doses plus 1 week without treatment represents a single 3 week cycle). Treatment can be continued without a rest period in the absence of progression of disease or unacceptable toxicity.

Eligibility Criteria

        Inclusion Criteria:

          -  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 and has at least 2+
             staining for Trop-2.

               -  Must have availability of archival tumor tissue FFPE block for TROP-2 testing

          -  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, Granulocytes greater than or
             equal to 1500/ul.

          -  Patients must have adequate renal function: creatinine less than or equal to 2.0

          -  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

          -  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

          -  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

          -  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.
