A RANDOMIZED PHASE 3 TRIAL OF TRC105 AND PAZOPANIB VERSUS PAZOPANIB ALONE IN PATIENTS WITH ADVANCED ANGIOSARCOMA (TAPPAS)
This is a study of TRC105 in combination with standard dose pazopanib compared to single
agent pazopanib in patients with angiosarcoma not amenable to curative intent surgery (e.g.,
metastatic or bulky disease, and disease for which surgical resection would carry an
unacceptable risk to the patient) who have not received pazopanib or TRC105 previously.
agent pazopanib in patients with angiosarcoma not amenable to curative intent surgery (e.g.,
metastatic or bulky disease, and disease for which surgical resection would carry an
unacceptable risk to the patient) who have not received pazopanib or TRC105 previously.
TRC105 (carotuximab) is a monoclonal antibody to endoglin (CD105), an essential angiogenic
target highly expressed on tumor vessels that is distinct from VEGFR. Endoglin is also
expressed directly on tumor cells in angiosarcoma and is upregulated following VEGF
inhibition. TRC105 inhibits angiogenesis, tumor growth and metastases in preclinical models
and complements the activity of bevacizumab and multi-kinase inhibitors that target the
VEGFR.
Pazopanib is an oral inhibitor of multiple receptor tyrosine kinases, including vascular
endothelial growth factor receptor (VEGFR)-1, VEGFR-2, and VEGFR-3 at therapeutic plasma
concentrations. These receptors are implicated in pathologic angiogenesis, tumor growth, and
cancer progression.
By targeting a non-VEGF pathway that is upregulated following VEGF inhibition, TRC105 has the
potential to complement VEGFR tyrosine kinase inhibitors (TKIs) and could represent a major
advance in the treatment of angiosarcoma. Together, the use of TRC105 with pazopanib may
result in more effective angiogenesis inhibition and improved clinical efficacy over that
seen with pazopanib alone.

Inclusion Criteria:
1. Histologically-confirmed angiosarcoma that is not amenable to curative intent surgery
(e.g., metastatic or bulky disease and disease for which surgical resection would

sponsor prior to randomization.
2. Documented progression on or following most recent systemic chemotherapy regimen (not
required for chemotherapy-naïve patients), within 4 months prior to screening

beginning in Cohort 2 if weight ≥ 40 kg
5. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1
6. Resolution of all acute AEs resulting from prior cancer therapies to National Cancer
Institute Common Terminology Criteria for Adverse Events version 4.03 (NCI CTCAE
v4.03) grade ≤ 1 or to that patient's pre-study baseline (except alopecia or
neuropathy)
7. Adequate organ function
8. Willingness and ability to consent (and assent if under age 18) for self to
participate in study
9. Willingness and ability to comply with scheduled visits, treatment plan, laboratory
tests, and other study procedures
10. Angiosarcoma tumor specimen, if available
11. Men who are sterile (including vasectomy confirmed by post vasectomy semen analysis)
OR agree to use a condom with spermicide (refer to Section 2.6.1.3) and to not donate
sperm during the study and for at least 180 days following last dose of TRC105 or
pazopanib
12. Woman of non-child bearing potential due to surgical sterilization (at least 6 weeks
following surgical bilateral oophorectomy with or without hysterectomy or tubal
ligation) confirmed by medical history or menopause (i.e., no menstrual bleeding for
more than 12 months in a women aged 45 years or more), OR woman of child bearing
potential who test negative for pregnancy at time of enrollment based on serum
pregnancy test and agree to use at least 2 acceptable methods of birth control, one of
which must be highly effective, during the study and for at least 180 days after
stopping TRC105 or pazopanib
Exclusion Criteria:
1. Prior treatment with TRC105
2. Prior treatment with any VEGF inhibitor
3. More than two prior lines (may be combination regimens) of chemotherapy for
angiosarcoma (neoadjuvant/adjuvant treatment does not count as a line of treatment)
4. Current treatment or participation on another therapeutic clinical trial
5. Women who are pregnant or breastfeeding
6. Receipt of systemic anticancer therapy, including investigational agents, within 5
times the agent's elimination half-life of starting study treatment
7. Major surgical procedure or significant traumatic injury within 4 weeks prior to
randomization and must have fully recovered from any such procedure or injury; planned
surgery (if applicable) or the anticipated need for a major surgical procedure within
the next six months. Note: the following are not considered to be major procedures and
are permitted up to 7 days before randomization: Thoracentesis, paracentesis, port
placement, laparoscopy, thoracoscopy, tube thoracostomy, bronchoscopy, endoscopic
ultrasonographic procedures, mediastinoscopy, skin biopsies, and imaging-guided biopsy
