Multicenter, Open-Label Phase II Study of Daily Oral Regorafenib for Chemotherapy-Refractory, Metastatic and Locally Advanced Angiosarcoma

The purpose of this study is to see whether a drug called regorafenib might be effective in
treating angiosarcoma. This study is for patients who have angiosarcoma that has gotten worse
after they received chemotherapy. Regorafenib is a type of drug called a kinase inhibitor.
Regorafenib interferes with how some kinase proteins work. Some of these kinases in cancer
cells might normally help the cancer cells grow or form new blood vessels that could feed a
growing tumor. By blocking these proteins, regorafenib may help stop the growth of certain


I. To define the progression-free survival (PFS) at 4 months with daily oral regorafenib (160
mg) in previously treated locally advanced/metastatic angiosarcoma patients


I. Progression-free rate at 3 and 6 months. II. Progression-free survival. III. Overall
survival (up to 5 years). IV. Response rate (by Response Evaluation Criteria in Solid Tumors
[RECIST] version [v] 1.1).

V. Rate and duration of tumor control (complete response [CR] + partial response [PR] +
stable disease [SD]).

VI. Safety/tolerability of regorafenib.


Patients receive regorafenib orally (PO) once daily (QD) on days 1-21. Courses repeat every
28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 5

Inclusion Criteria:

- Life expectancy of at least 4 months

- Histologically confirmed angiosarcoma

- Tumor deemed unresectable or metastatic

- Measurable disease per RECIST v 1.1

- Progressive disease under last palliative therapy with a history of prior ifosfamide,
doxorubicin or taxane therapy for angiosarcoma; up to 4 prior therapies are allowed

- All acute toxic effects of any prior treatment have resolved to grade 1 or less (by
National Cancer Institute-Common Terminology Criteria for Adverse Events [NCI-CTCAE] v
4.0) at the time of registration; NOTE: Exceptions to this criterion will include
alopecia and fatigue

- Total bilirubin =< 1.5 x the upper limits of normal (ULN)

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN (=< 5
x ULN for subjects with liver involvement of their cancer)

- Alkaline phosphatase limit =< 2.5 x ULN (=< 5 x ULN for subjects with liver
involvement of their cancer)

- Lipase =< 1.5 x the ULN

- Serum creatinine =< 1.5 x the ULN

- International normalized ratio (INR)/partial thromboplastin time (PTT) < 1.5 x ULN

- Platelet count > 100000/mm^3

- Hemoglobin > 9 g/dL

- Absolute neutrophil count > 1500/mm^3

- If baseline urine protein creatinine (UPC) >= 1, a 24-hour urine protein must be
assessed; patients must have a 24-hour urine protein value < grade 3 (> 3.5 g/24
hours) to be eligible

- NOTE: Blood transfusion to meet the above criteria will not be allowed; NOTE: Patients
who are prophylactically 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 must have a negative serum pregnancy test performed
within 7 days prior to the start of study drug; post-menopausal women (defined as age
>= 50 years and no menses for at least 1 year) and surgically sterilized women are not
required to undergo a pregnancy test

- Subjects (men and women) of childbearing potential must agree to use adequate
contraception beginning at registration until at least 3 months after the last dose of
study drug; the definition of adequate contraception will be based on the judgment of
the principal investigator

- Subject must be able to swallow and retain oral medication

- Subjects must be able to understand and be willing to sign the written informed
consent form; a signed informed consent form must be appropriately obtained prior to
the conduct of any trial-specific procedure

Exclusion Criteria:

- Uncontrolled hypertension (systolic pressure > 140 mmHg or diastolic pressure > 90
mmHg on repeated measurement) despite optimal medical management

- Active or clinically significant cardiac disease including:

- Congestive heart failure - New York Heart Association > class II

- Active coronary artery disease

- Cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or

- Unstable angina (anginal symptoms at rest), new-onset angina within 3 months
before registration, or myocardial infarction within 6 months before registration

- Evidence or history of bleeding diathesis or coagulopathy

- Any hemorrhage or bleeding event grade 3 within 4 weeks prior to registration

- Subjects with thrombotic, embolic, venous, or arterial events, such as cerebrovascular
accident (including transient ischemic attacks), deep vein thrombosis or pulmonary
embolism within 6 months of informed consent

- Subjects with any previously untreated or concurrent cancer unrelated to angiosarcoma;
NOTE: Exceptions include cervical cancer in-situ, treated basal cell carcinoma, or
superficial bladder tumor; subjects surviving a cancer that was curatively treated and
without evidence of disease for more than 3 years before registration are allowed; all
treatments must have been completed at least 3 years prior to registration

- Patients with pheochromocytoma

- Patients with severe hepatic impairment (Child-Pugh class C)

- Known history of human immunodeficiency virus (HIV) infection or current chronic or
active hepatitis B or C infection requiring treatment with antiviral therapy

- Ongoing infection > grade 2

- Evidence of significant central nervous system disease including seizure disorder
requiring medication, symptomatic metastatic brain or meningeal tumors

- Presence of a non-healing wound, non-healing ulcer, or bone fracture

- Renal failure requiring hemo-or peritoneal dialysis

- Dehydration > grade 1

- Interstitial lung disease with ongoing signs and symptoms at the time of registration

- Pleural effusion or ascites that causes respiratory compromise (>= grade 2 dyspnea)

- History of organ allograft (including corneal transplant)

- Known or suspected allergy or hypersensitivity to any of the study drugs, study drug
classes, or excipients of the formulations given during the course of this trial

- Any malabsorption condition

- Evidence of abdominal fistula, gastrointestinal (GI) perforation or intraabdominal

- Women who are pregnant or breast-feeding

- Concurrent anti-cancer therapy (chemotherapy, surgery, immunotherapy, biologic
therapy, or tumor embolization) other than study treatment (regorafenib)

- Prior use of regorafenib

- Prior use of sorafenib

- Therapeutic anticoagulation with Vitamin-K antagonists (e.g., warfarin) or with
heparins and heparinoids; NOTE: Prophylactic anticoagulation as described below is

- Low dose warfarin (1 mg orally, once daily) with prothrombin time
(PT)-international normalized ratio (INR) =< 1.5 x ULN is permitted; infrequent
bleeding or elevations in PT-INR have been reported in some subjects taking
warfarin while on regorafenib therapy; therefore, subjects taking concomitant
warfarin should be monitored regularly for changes in PT, PT-INR or clinical
bleeding episodes

- Low dose aspirin (=< 100 mg daily)

- Prophylactic doses of heparin

- Any condition which, in the investigator's opinion, makes the subject unsuitable for
trial participation
