6. Immunoembolization
Rationale
• Destruction of tumor by embolization would control
tumor progression locally and provide tumor antigens to
the local immune system
• Concurrent use of biological response modifier(s) induces
an inflammatory response in the tumor and surrounding
tissue which may improve the antigen presentation to the
local immune system
• Local stimulation of the immune system may result in the
development of a systemic immune response against
tumor cells which may suppress the growth of untreated
tumors
• IE could potentially create an in situ tumor vaccine.

7. Immunoembolization
Granulocyte-Macrophage Colony-Stimulating Factor
• Glycoprotein secreted by activated T cells
• LEUKINE (sargramostim) is a recombinant yeast-
derived human GM-CSF
• Increases myeloid cell production
• Stimulates macrophages
• Increases cytotoxicity of monocytes toward tumor
cell lines
• Promotes maturation of dendritic cells

8. Immunoembolization
Selection of GM-CSF
Vaccination was performed with 10 tumor cell
lines engineered to secrete different cytokines
Proc Natl Acad Sci 1993; 90: 3539-3543

9. Immunoembolization
Phase 1 Study – Intro
• Purpose was to investigate feasibility and safety
• 2000 – 2004, single institution
• 34 of 39 patients had MUM
• <50% tumor involvement, unresectable
• Lobar hepatic artery embolization every 4 weeks using
escalating dose of GM-CSF (25-2000 mcg) emulsified
with Ethiodol followed by Gelfoam, for 6 treatments
• Imaging (CT, MRI) and clinical assessment after
every other treatment to assess response (RECIST)
• Primary end-points were dose-limiting toxicity and
maximum tolerated dose
J Clin Oncol 2008; 26:5436-5442

10. Immunoembolization
Phase 1 Study – Results (n=34)
• 6 procedures/patient (median, range 1-14)
• 32% responded (2 CR, 8 PR)
• 32% stable disease
• OS: 14.4 months (median)
(33.7 months for CR/PR, 12.4 months SD/PD)
• Survival: 1 yr. 62%, 2 yr. 26%
• PFS-liver: 4.8 months (median)
• PFS-systemic: 10.4 months (median)

13. Immunoembolization
Dose-Related Response (n=31)
Patients undergoing high-dose IE (>1500 mcg) vs.
low-dose IE (<1000 mcg):
• Longer OS (20.4 vs. 13.0 months, median)
• Longer PFS-L (9.3 vs. 4.2 months, median)
• Longer PFS-S (12.4 vs. 5.6 months, median)*
* P < .05
Radiology 2009; 252:290-298

14. Immunoembolization
Comparison to BCNU TACE
Patients undergoing high-dose IE (>1500 mcg) vs.
TACE with BCNU (TJUH Phase II study, excluding
patients with >50% tumor burden in liver):
• Longer OS (20.4 vs. 9.8 months, median)*
• Longer PFS-L (9.3 vs. 6.4 months, median)
• Longer PFS-S (12.4 vs. 4.8 months, median)*
* P < .05
Radiology 2009; 252:290-298

15. Immunoembolization
Comparison to BCNU TACE
• No significant difference in overall or progression-free
survival between patients who received BCNU TACE
and lower dose IE
• Stabilization of hepatic metastases was most likely
achieved by the ischemic effects of embolization rather
than by the administered medication
• Systemic progression was delayed in the high-dose IE
group, suggesting an induction of a systemic immune
response against the melanoma cells

16. Immunoembolization
Additional observations -
• Tumor regression was sustained after discontinuation of
immunoembolization in several patients
• Response can take as long as 4 months (4 IE procedures)
• Evidence of activation of the memory cell arm of the
immune system (T cells), suggesting a tumor vaccine
Repeated immune stimulation has been shown to be
necessary to overcome tolerance and induce a vigorous
response (J Exp Med 1997; 186: 645-653 & J Clin Invest 1998; 101:2406-2414)

17. Immunoembolization of the Hepatic Artery with
Granulocyte-Macrophage Colony Stimulating Factor
• R21 study
• Randomized, double blind, phase II clinical study for
MUM patients
• Primary endpoint – regression of liver mets
• Secondary endpoint – time to progression, overall survival,
and development of local/systemic immune response
• 52 patients – randomized to receive embolization using
Ethiodol, with or without 2000 mcg GM-CSF, followed by
Gelfoam
• Stratified by liver involvement (<20% vs. 20-50%) and
HLA-A2 status

18. Immunoembolization of the Hepatic Artery with
Granulocyte-Macrophage Colony Stimulating Factor
• Excludes patients with >50% tumor involvement,
extrahepatic mets, prior local liver therapies
• Lobar treatments every 4 weeks with imaging (CT, MRI)
and clinical assessment every 8 weeks (RECIST)
• Investigation of biopsy specimens before/after treatment
• Analysis of peripheral blood mononuclear cells and serum
to assess systemic immune response
• 52 patients enrolled beginning June 2005
• Last treatment under protocol April 2010
• 2 completed (24 months)
• 51 patients (98%) are deceased

19. Immunoembolization of the Hepatic Artery with
Granulocyte-Macrophage Colony Stimulating Factor
Results – Phase II Trial
• Both immunoembolization (IE) and bland embolization were
well tolerated with acceptable toxicity
• Both approaches induced cytokine productions, more
prominent in patients treated with IE
• IE showed a potential overall survival benefit in patients with
20-50% tumor replacement
• Trend towards longer PFS-S following IE
• Unexpectedly, PFS-L was shorter following IE in patients
with <20% tumor involvement, suggesting a suppressive
(paradoxical) response to high dose GM-CSF

Granulocyte-Macrophage Colony Stimulating Factor
Phase II Trial
JVIR 2015; 26:523-532

21. Immunoembolization
Phase II Trial - Results
• Not powered to determine survival benefit; designed as proof
of concept study to investigate hypothesis that adding GM-CSF
to embolization would increase release of pro-inflammatory
cytokines and delay development of extrahepatic metastases
• Plain embo – increases in IL-6 and IL-8 > 18 hrs.
• Immunoembo – significant (P<0.001) and rapid increase in
TNF-a, IL-6, and IL-8 at 1 and 18 hrs post treatment,
suggesting faster and more robust inflammatory response
• Increased IL-6 level at 1 hr and IL-8 level at 18 hrs correlated
with delay in onset of extrahepatic metastases with a dose-
response pattern
• Double-blind, randomized clinical trial comparing bland
embolization to drug + embolization, showing a benefit of
adding the drug

70. Microwave Ablation
• Microwave needle is placed
directly into the liver tumor
• Using CT or US guidance
• Generates heat to destroy
tumor cells
• Reserved for patients with a
solitary metastasis or for a
single “rogue” tumor that
won’t respond to
transarterial liver-directed
therapies

71. Microwave Ablation
Oligometastasis –
• 7 patients, median 1.7 cm diameter
• 4 with no intrahepatic progression, 11-37 months
• 3 with intrahepatic progression 1-8 months
(2 died at 23-24 months)
“Rogue Tumor” –
• 6 patients, median 2 cm diameter
• 1 patient no progression at 36 months
• 5 patients intrahepatic progression at median 5
months (1 – 11), 1 died at 27 months

72. Microwave Ablation
IE treatments starting 10-16-2012. All tumors
responded except for one.

years after initiating treatment at TJUH.

73. Current Jefferson Treatment Algorithm
for Liver Metastases in MUM Patients
Following consideration of resection/ablation (rare):
If < 50% liver involvement, limited extrahepatic mets:
• Immunoembolization (especially minimal disease)
• SIRspheres
If < 50% liver involvement, limited extrahepatic mets,
largest tumor > 5-6 cm:
• DEBDOX followed by BCNU Chemoembolization
If > 50% liver involvement with liver dominant disease:
• Chemoembolization (BCNU, DEBDOX)
Progression following immunoembolization:
• SIRspheres (<50% tumor burden)
• Chemoembolization (BCNU, DEBDOX)
Clinical Trials (including Delcath/PHP)! gp100!!!

74. Future Considerations when Evaluating
Treatment of Liver Metastases in MUM Patients
Comparison of Treatments and Stratification of
Results based on –
• Tumor Burden
• Tumor Genetics
• Pattern of Disease in the Liver
(nodular vs. infiltrative)
Adjust for delay in treatment of one lobe of the
liver when using liver-directed treatments in
clinical trials (allow repeat baseline MRI)
