Phase II Study of Regorafenib as Maintenance Therapy

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Metastatic Soft Tissue Sarcoma
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

Inclusion Criteria:

  • Age 18 years
  • Histologically proven soft tissue sarcoma including leiomyosarcoma, synovial sarcoma and other sarcomas
  • Patients in partial response or stable disease after 6 cycles of doxorubicin-based first-line chemotherapy for metastatic/locally advanced soft tissue sarcoma
  • Metastatic/locally advanced disease not amenable to surgical resection with curative intent
  • Eastern Cooperative Oncology Group (ECOG) Performance Status =0 or 1
  • Measurable disease, defined as at least 1 unidimensionally measurable lesion on a CT scan as defined by RECIST 1.1.
  • Available tumor tissue for translational research program
  • Adequate bone marrow, renal, and hepatic function, as evidenced by the following within 7 days of study treatment initiation:
  • Absolute neutrophil count (ANC) 1,500/mm3
  • Platelets 100,000/mm3
  • Hemoglobin 9.0 g/dL
  • Serum creatinine 1.5 x upper limit of normal (ULN)
  • Glomerular filtration rate (GFR) 30 ml/min/1.73m2
  • AST and ALT 2.5 x ULN ( 5.0 ULN for patients with liver involvement of their cancer)
  • Bilirubin 1.5 X ULN
  • Alkaline phosphatase 2.5 x ULN (5 x ULN with liver involvement of their cancer)
  • Lipase 1.5 x ULN
  • Spot urine must not show 1+ or more protein in urine or the patient will require a repeat urine analysis. If repeat urinanalysis shows 1+ protein or more, a 24-hour urine collection will be required and must show total protein excretion <1000 mg/24 hours
  • INR/PTT 1.5 x ULN (Patients who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring of at least weekly evaluations will be performed until INR/PTT is stable based on a measurement that is pre-dose as defined by the local standard of care.)
  • Women of childbearing potential and male subjects must agree to use adequate contraception for the duration of study participation and up to 3 months following completion of therapy. Adequate contraception is defined as any medically recommended method (or combination of methods) as per standard of care.
  • Recovery to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.0 Grade 0 or 1 level or recovery to baseline preceding the prior treatment from any previous drug/procedure related toxicity (except alopecia, anemia, and hypothyroidism).
  • In the assessment of the investigator, patients are able to comply with study requirements
  • Signed, IRB-approved written informed consent
  • Patient covered by the French "Social Security" regime
