Clinical Research Trials

Key Trial Criteria

• Key Inclusion Criteria

  For a patient to be eligible for participation in this study, all of the following criteria must apply.

  • Histologically confirmed cutaneous or visceral angiosarcoma, where curative treatment is either not possible or curative modality therapy is declined by the subject. Note: If a subject declines curative modality therapy, the reason must be documented (e.g. excessive morbidity to necessary surgery)
    • Note: Radiation induced angiosarcomas are permitted
      • All local diagnostic slides AND 5 x 4-6 micron unstained slides from diagnostic tumor tissue should be available for retrospective central pathology review
  • Must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1. Per RECIST v1.1, clinical lesions will only be considered measurable when they are superficial and P10 mm diameter as assessed using calipers or ruler (e.g. skin nodules). For the case of skin lesions, documentation by color photography including a ruler to estimate the size of the lesion is required. When lesions can be evaluated by both clinical exam and imagining, imaging evaluation should be undertaken since it is more objective and may also be reviewed at the end of the study. The same method of measurement should be used throughout the study, preferably performed by the same investigator. Areas previously radiated must have demonstrated disease progression at some point over the past 6 months and growth must be subsequent to the last line of anti-cancer directed therapy (e.g. chemotherapy, radiation therapy, surgery)
  • Not pregnant and not nursing, because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown
    • Therefore, for women of childbearing potential only, a negative pregnancy test done =< 3 days prior to registration is required
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-1
  • Prior Treatment
    • Patient must have completed all prior treatments (including investigational) >= 28 days prior to cycle 1 day 1
      • Exception: prostate patients who are allowed to concurrently receive androgen suppression therapy
      • Exception: Targeted small molecule chemotherapy or radiation must be completed >= 14 days of day 1 of study treatment. For targeted chemotherapies, prior therapies must be completed prior to registration and final dose must have occurred > 5 half-lives prior to cycle 1 day 1
    • There is no limit to overall number of prior lines of therapy
    • No prior PD-1 inhibitor or PD-L1 inhibitor therapy is permitted
    • No prior administration of VEGF TKI therapy is permitted
    • Recovery to baseline or' =< grade 1 CTCAE version 5.0 from toxicity related to any prior treatment, unless adverse events are clinically nonsignificant and/or stable on supportive therapy, with the exception of fatigue (which should be =< grade 2) or alopecia
  • Taxane Naive Patients Only: No prior exposure to taxane therapy of any duration for angiosarcoma
  • Taxane Pre-treated Patients Only: Prior taxane therapy is allowed at any point prior to registration as long as it is >= 28 days prior to cycle 1 day 1

  • Urine protein:creatinine (UPC) ratio < 1 or urine protein =< 1+
  • No uncontrolled central nervous system (CNS) metastases. Patients with history of CNS metastasis will be allowed as long as the metastatic sites were adequately treated as demonstrated by clinical and radiographic improvement, and the patient has recovered from the intervention (no residual adverse events > CTCAE grade 1), and the patient has remained without recurrence of new or worsening CNS symptoms for a period of 28 days prior to registration. Treated CNS metastasis (mets) should have no ongoing requirement for steroids, and no evidence of hemorrhage after treatment for at least 28 days prior to registration
  • No uncontrolled intercurrent illness that would put the patient at undue risk by participation in the study, in the opinion of the investigator
  • No history of syncope of cardiovascular etiology, uncontrolled cardiac arrhythmia, History of Mobitz II second degree or third degree heart block without a permanent pacemaker in place, myocardial ischemia or infarction, severe or unstable angina, New York Heart Association (NYHA) class II to IV heart failure, or stroke/transient ischemic attack (TIA) within the past 3 months

These include but are not limited to patients with a history of immune-related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), rheumatoid arthritis, connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease
