| Eligibility |
Inclusion Criteria:
1. Male or female subjects age = 22 years old
2. Subjects with confirmed finding of hypervascular tumor on CT and/or MRI for whom TAE
or cTACE is medically indicated, including but not limited to:
1. Subjects with unresectable primary or metastatic hepatic cancer
2. Subjects with primary, metastatic or benign renal tumors
3. Subjects with bone metastases
4. Subjects with adrenal tumors
5. Subjects with other hypervascular tumors
3. Subjects with at least one target lesion that is well-delineated such that, in the
Investigator's opinion, the lesion can be measured in at least one dimension as 1 cm
or more, suitable for remeasurement, and demonstrating definitive arterial enhancement
(Note: Pre-operative tumors do not need to meet this criterion.)
4. Subjects with at least one target vessel = 5mm and Instylla HES can be delivered to
the target vessel(s).
5. Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-2 (PS 0-1 for
metastatic disease)
6. Subject or authorized representative have been informed of the nature of the study and
has provided written informed consent approved by the appropriate local Ethics
Committee/Institutional Review Board and agrees to comply with all protocol specified
follow-up appointments.
7. Expected life expectancy = 6 months after Index embolization
Exclusion Criteria:
1. Embolization for lesions other than hypervascular tumors such as arteriovenous
malformations.
2. It is anticipated that not all target vessels requiring embolization during the index
procedure can be embolized with either HES alone or the SOC embolization agent as
assigned.
3. Undergoing radioembolization or DEB-TACE for Index Procedure
4. Undergoing a planned secondary procedure the same day as the Index Procedure
5. Requires TAE/cTACE for liver tumors via extrahepatic collateral artery(ies)
6. Prior radioembolization of the target tumor lesion/vascular bed within 30 days of the
Index Procedure.
7. For subjects with HCC or undergoing embolization to the liver: Child-Pugh Class C or
presence of complete portal vein thrombosis.
8. Tumor lesions > 8 cm in diameter (in one direction) or >50% tumor volume burden of the
target organ
9. If subject was treated with Avastin, last dose is within 4 weeks of the planned
procedure.
10. Known severe atheromatosis or vascular anatomy that precludes catheterization
11. Presence of bilioenteric anastomoses and/or prior biliary stenting/drainage or any
violation of the biliary sphincter, including sphincterotomy for embolization of liver
tumors
12. Target lesion supplied by the pulmonary artery, coronary artery, or cerebral or
cerebellar artery (requiring embolization of these arteries) or the artery to be
embolized has connections to these arteries via a collateral pathway
13. Known allergies (based on history) to PEG, ferrous compounds, tert Butyl
Hydroperoxide, contrast media or procedural sedatives/anesthetics that is not amenable
to pre-medication
14. Uncorrectable impaired clotting: Platelet count <30,000/µL or International Normalized
Ratio (INR) > 1.5
15. Serum creatinine > 2 mg/dL
16. Serum bilirubin level > 3 mg/dL
17. Serum albumin < 2.5 g/dL
18. Any contraindication to angiography or embolization protocol utilized at treating
institution.
19. Pregnant or breast-feeding or females planning on becoming pregnant with the next 3
months (women of child-bearing potential must undergo a pregnancy test performed in
accordance with local institutional requirements).
20. Other concurrent conditions including an ongoing adverse effect or complication of
prior therapy or adverse drug reactions, that in the opinion of the Investigator or
Clinical Events Committee, would be unlikely to receive clinical benefit from the
study procedure or participation in the study may compromise subject safety or study
objectives (including but not limited to ongoing acute infection, renal dysfunction,
morbid obesity, severe cardiac disease).
21. Enrollment in a concurrent study in which the study treatment may confound the
evaluation of the study device
