Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study aims to determine the activity of eribulin as a single agent and the combination of eribulin and pembrolizumab as measured by clinical benefit rate (CBR) at 12 weeks.
Additionally, the study aims to establish whether high mobility group A2 (HMGA2) protein expression is a good functional biomarker to predict response to eribulin and pembrolizumab.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The underlying study rationale is based on robust preclinical evidence that demonstrated that eribulin, a microtubule inhibitor, can reprogram the tumour microenvironment, reversing epithelial mesenchymal transition (EMT) in these mesenchymal cancers, and potentiate the response to immune checkpoint blockade.
In addition, expression of HMGA2, a high mobility group protein has been associated with activation of EMT process and may be a predictive biomarker of eribulin-responsive cancers. This study is aimed at translating these laboratory findings to the clinic and treat patients with recurrent OCS and UCS with eribulin and the immune checkpoint inhibitor pembrolizumab, which targets and blocks the programmed cell death receptor 1 (PD-1).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Arm 1 - Single agent eribulin arm
Eribulin until progression of disease (PD) as defined by RECIST v1.1, unacceptable toxicity or physician/patient discretion or choice to cease treatment.
Patients who progress on the single agent eribulin arm may receive combination eribulin and pembrolizumab.
Eribulin Mesylate
Eribulin mesilate is a first-in-class halichondrin B-based, microtubule dynamics inhibitor7. It inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into non-productive aggregates.
Arm 2 - Combination eribulin and pembrolizumab arm
Eribulin for a maximum of 6 cycles. Pembrolizumab until PD or a maximum of 35 cycles (including the 6 cycles where it is administered in combination with eribulin) or until unacceptable toxicity or physician/patient discretion or choice to cease treatment.
Eribulin Mesylate
Eribulin mesilate is a first-in-class halichondrin B-based, microtubule dynamics inhibitor7. It inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into non-productive aggregates.
Pembrolizumab
Pembrolizumab is a potent humanized immunoglobulin G4 (IgG4) monoclonal antibody (mAb) with high specificity of binding to the programmed cell death 1 (PD 1) receptor, thus inhibiting its interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients \> 18 years old who have a histologically confirmed tubo-ovarian carcinosarcoma or uterine carcinosarcoma with evidence of recurrence or progression. The component of sarcoma in the diagnostic pathology sample must be equal to or \> 5% of tumour.

4. Must have at least one evaluable measurable lesion (other than the lesion that will be used for biopsy) using standard techniques according to the Response Evaluation Criteria in Solid Tumours (RECIST v1.1) guidelines (Appendix 1).
5. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 (Appendix 5). Evaluation of ECOG is to be performed within 28 days prior to the first dose of the study intervention.
6. Have adequate organ function as defined below (refer also Appendix 6).
* Absolute neutrophil count (ANC) ≥1.5 x 109/L
* Platelets ≥100 x 109/L
* Haemoglobin (Hb) ≥90 g/L or ≥5.6 mmol/L (criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks).
* Creatinine ≤ 1.5 x Upper Limit Normal (ULN); OR Creatinine Clearance (CrCl) ≥ 30 mL/min (calculated per institutional standard) for participants with creatinine levels \>1.5 ULN (glomerular filtration rate, GFR, can also be used in place of creatinine or CrCl). (Patients with moderate renal impairment (CrCl 30-49ml/min) will receive a 25% reduced dose of eribulin).
* Total bilirubin ≤1.5 ×ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels \>1.5 × ULN
* Alkaline phosphatase (ALP), Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 × ULN (≤5 × ULN for participants with liver metastases)
* International normalized ratio (INR) OR prothrombin time (PT), Activated partial thromboplastin time (aPTT) ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants Biological specimens must be collected within 28 days prior to the first dose of the study intervention (within 7 days, where indicated in the SoA).
