Eribulin Mesylate and Radiation Therapy in Treating Patients with Retroperitoneal Liposarcoma That Can Be Removed by Surgery

Trial Status: Active

This phase Ib trials studies the side effects and best dose of eribulin mesylate when given together with radiation therapy in treating patients with retroperitoneal liposarcoma that can be removed by surgery. Drugs used in chemotherapy, such as eribulin mesylate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells.

Inclusion Criteria

  • Pathologically confirmed diagnosis of liposarcoma; all subtypes are eligible
  • Sufficient archival tissue available for correlative studies; submission of formalin-fixed paraffin-embedded (FFPE) tumor tissue from a previous biopsy or resection is required, and the most recent specimen is preferred; if a FFPE block cannot be provided, then 10 unstained, positively-charged slides of 4-5 um thickness must be submitted; if insufficient archival tissue is available, a repeat biopsy will be necessary
  • Primary or recurrent retroperitoneal, scrotal/spermatic cord or abdominal tumor
  • For subjects between the ages of 12-18 years only, body surface area (BSA) must be >= 1.5 m^2
  • All sites of disease must be resectable or borderline resectable as assessed by a surgical oncologist with experience in retroperitoneal sarcoma resection after discussion in our institutional multidisciplinary sarcoma tumor board conference
  • All sites of disease must be targetable with intensity-modulated radiation therapy (IMRT) with acceptable morbidity and without exceeding normal tissue dose constraints as assessed by a radiation oncologist
  • Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  • Female subjects of childbearing potential must have a negative urine beta-human chorionic gonadotropin (beta-hCG) pregnancy test at time of screening
  • Fridericia's correction formula (QTcF) interval on standard 12-lead electrocardiography (ECG) parameters at screening (defined as the mean of the triplicate ECGs) of < 450 msec for males and < 470 msec for females
  • Ejection fraction of >= 50%
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (Karnofsky >= 70%)
  • Men and women of childbearing potential must be willing to use adequate contraception throughout the study and for 3 weeks after study drug discontinuation
  • Absolute neutrophil count (ANC) >= 1 K/cu mm
  • Platelets (no transfusion within prior 7 days) >= 100 K/cu mm
  • Hemoglobin (no transfusion within prior 7 days) >= 9.0 g/dL
  • Total bilirubin < institutional upper limit of normal (ULN), except for subjects with documented Gilbert’s syndrome, for which =< 3.0 x ULN or direct bilirubin =< 1.5 x ULN
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN
  • Estimated creatinine clearance > 50 mL/min by Cockcroft-Gault equation
  • Ability to understand and the willingness to sign a written informed consent document; subject has signed the informed consent (ICF) prior to any screening procedures being performed and is able to comply with protocol requirements

Exclusion Criteria

  • Presence of distant metastases; intra-abdominal (regional) spread is allowable if meets inclusion criterial indeterminate or small volume pulmonary nodules may be eligible, if the treating physicians recommend curative-intent resection of the primary tumor despite the presence of possible lung metastases
  • Prior radiation or systemic therapy for the diagnosis of liposarcoma
  • Prior eribulin
  • Grade >= 2 peripheral neuropathy
  • Contraindication to magnetic resonance imaging (MRI), including presence of a pacemaker or aneurysm clip, severe claustrophobia, a known reaction to gadolinium contrast, or body weight exceeding 300 pounds (lbs)
  • Concurrent malignancy or malignancy within 3 years prior to starting study drug, with the exception of malignancies that have completed therapy and are considered by their physician to be at less than 30% risk of relapse; prior systemic therapy is allowed with the exception of prior eribulin; prior radiation therapy is allowed with the exception of any abdominal, pelvic or retroperitoneal radiation > 10 Gy
  • History of uncontrolled arrhythmia, congenital long QT syndrome or torsades de pointes (TdP)
  • Use of more than one medication with a known risk of TdP
  • Major operation within 14 days prior to starting study drug or not recovered from surgical complications; neither tumor biopsy nor central line insertion are considered a major operation
  • Active infection; any systemic antimicrobial therapy must be completed >= 5 days prior to initiation of protocol therapy
  • Pregnant or nursing (lactating) women; NOTE: Pregnant women are excluded from this study because eribulin is an investigational agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with eribulin breastfeeding should be discontinued; these potential risks may also apply to doxorubicin
  • Unable or unwilling to stop the use of herbal supplements; the use of marijuana or its derivatives is allowed; the use of supplements may be allowed after review by a study pharmacist to confirm no significant risk of interaction with eribulin or radiation

I. To determine the recommended phase 2 dose (RP2D) of radiation and eribulin mesylate (eribulin) when used in combination for the preoperative treatment of retroperitoneal liposarcoma.


I. To assess the feasibility of a preoperative chemoradiation protocol for retroperitoneal liposarcoma.

II. To assess the surgical outcomes of retroperitoneal liposarcoma resections after preoperative chemoradiation.

III. To assess preliminary anti-tumor activity of eribulin in combination with radiation in subjects with retroperitoneal liposarcoma.

OUTLINE: This is a dose-escalation study of eribulin mesylate.

Patients receive eribulin mesylate intravenously (IV) over 2-5 minutes on days 1 and 8 and undergo intensity-modulated radiation therapy once daily (QD) 5 days a week beginning on day 8 of cycle 1. Treatment repeats every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients may undergo surgery within 3-10 weeks after radiation therapy.

After completion of study treatment, patients will be followed up at 2 weeks, 9 weeks, and then every 6 months for 10 years.
