Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Eribulin Mesylate
Treatment: Drugs - Pembrolizumab

Experimental: 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.

Experimental: 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.


Treatment: Drugs: 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.

Treatment: Drugs: 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).

* 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).
7. Available formalin fixed, paraffin embedded (FFPE) tumour sample from the primary cancer and/or metastatic tumour from the up-front or secondary debulking surgery with adequate neoplastic cell content (>30%).
8. Must have disease amenable to biopsy and must be willing to undergo a paired biopsy for additional correlative analyses (the first biopsy to be performed within 28 days prior to the start of the study intervention and the second biopsy in the five-day window prior to Cycle 2 (post Cycle 1)). For patients that experience progression of their disease whilst on study, separate patient consent will be sought for additional biopsies of their tumour for research.

Patients must be either off corticosteroids or on stable or decreasing dose of < /=10 mg daily prednisone (or equivalent) within 28 days prior to the first dose of the study intervention. In the case of short-term use of systemic corticosteroids (less than 24 hours within 28 days) of greater than 10 mg daily of prednisone or an equivalent corticosteroid, the required washout period prior to starting the first dose of the study intervention is 7 days. Anticonvulsants are allowed to be continued except for those which interfere with the study interventions or are associated with liver toxicity. However, patients receiving anticonvulsants must be discussed with Study Chair or Acting Chair of Trial Management Committee (TMC) prior to their enrolment to the study.
9. Symptomatic or clinically significant inflammatory bowel disease (Crohn's disease or ulcerative colitis).
