Cancer Treatment:
Drawbacks & Challenges
 Surgery, radiation & chemotherapy
• Not all patients who need the treatment are eligible
• Considerable adverse effects including death, pain, infections,
heart failure, fatigue, nausea/vomiting, etc
• Long-term sequelae – heart failure, pulmonary, secondary cancers
• Some cancer cells may survive causing progression or recurrence
 Tumor resistance
• Immune system has a critical role in cancer pathogenesis (ie:
immunocompromised patients)
• Solid organ transplant – 2-fold increase in solid tumors & 20fold increase in skin cancer, lymphoma & sarcomas
• HIV – 40% of AIDS patients develop cancer
• Tumors consist mainly of normal tissue components (self)
Cancer immunotherapy www.dendreon.com, BiTE antibodies www.amgenoncology.com
Cancer Treatment:
Drawbacks & Challenges
 Tumor resistance (cont.)
• Immune system is trained to avoid attacking itself
• Cytotoxic T lymphocytes (CTLs) recognize tumor antigens, bind &
cause tumor cell lysis
 Problem – tumors can evade T cell recognition (escape phase)
• Immune system exhaustion
• Tumor growth is too fast for immune system to keep up
• Checkpoints on the T cell (CTLA-4 & PD-1) are upregulated
causing the T cell to turn off
• Tumors can secrete immunosuppressive cytokines
 Solution – the new era of cancer treatment
• Encourage immune cells that recognize tumor
• Help immune system track down wandering cancer cells & destroy
them
• Develop tumor specific Ab’s outside the body & inject them into
patients
Cancer immunotherapy www.dendreon.com, BiTE antibodies www.amgenoncology.com
Cancer Treatment: A New Era
 Cytokines – T cell growth factors that stimulate immune response
(ie: interferons, interleukins)
 Allogeneic HSCT – tumor cells eliminated through high-dose
chemotherapy followed by graft-versus-tumor effect
 Monoclonal Antibodies – direct or indirect immune response
• Rituximab – immune-mediated cytotoxic response
• Trastuzumab & cetuximab – block signal pathways needed for
cell growth
• Bevacizumab – block angiogenesis needed for oxygen &
nutrients
• Brentuximab vedotin – antibody drug conjugate (ADC)
combining a monoclonal Ab with cyctotoxic drug
• Tositumomab 131I – antibody combined with radioactive
particle
 Oral molecular target drugs (aka tyrosine kinase inhibitors, signal
transduction inhibitors, “nibs”)

Cancer Treatment: A New Era
 Autologous cellular immunotherapy – activated APCs are
reinfused into patient to direct immune cells vs tumor cell
(ie: sipuleucel-T)
 Immune checkpoint inhibitors – “release the brakes” on
the immune system (ie: ipilimumab, nivolumab,
pembrolizumab)
 CAR-T therapy – chimeric antigen receptor (CAR) T cells
 Immunovirus – therapeutic cancer vaccine
 Future directions – BiTE antibodies, DNA methylation
signature, TMEM score, magic wands, IDH2 blockers,
proteomics, intraoperative radiation, CRISP-R technology

Immunotherapy:
Checkpoint inhibitors
 Immune system relies on multiple checkpoints to
avoid over activation on healthy cells
 Tumor cells hijack these checkpoints to escape
detection
 CTLA-4 & PD-1 are upregulated on T cell surface in
some cancers
 PD-L1 can be expressed on tumor cells
endogenously or induced by association with T cells
 PD-1:PD-L1 interaction results in T cell suppression
(anergy, exhaustion, death)

Immunotherapy:
Checkpoint inhibitors
 In melanoma, renal cell, & other tumors, PD-L1
expression is associated with more aggressive
disease
 Inhibiting CTLA-4 & PD-1 can “release the brakes”
 Checkpoint inhibitors don’t attack the tumor, they
set the T cells straight
 Activity powerful enough to work in the CNS – T cells
go everywhere
 Melanoma patients – on MRI, brain mets are
surrounded by tons of T cells

Immunotherapy: PD-1 inhibitors
 Disease can get worse before it gets better
 Four distinct response patterns associated with favorable
overall survival (OS)
• Response in baseline lesions
• Stable disease with slow decline in tumor volume
• Response following an initial increase in tumor volume
• Response following appearance of new lesions
 Infiltration of patient immune cells can cause an initial
increase in tumor volume or appearance of new lesions on
imaging scans (know as pseudoprogression)
 Need 8-12 doses to accurately evaluate patient response
Atkins MB et al. Clinical Care Options slideset 2014.
Immunotherapy: PD-1 inhibitors
 Immune-mediated toxicity
• Overall, gentler than CTLA-4 inhibitors
• Occasional (5-20%)
• Fatigue
• Rash – maculopapular, pruritis
• Diarrhea/colitis – initiate steroids early, taper slowly
• Hepatitis/liver enzyme abnormalities
• Infusion reactions
• Endocrinopathies – thyroid, adrenal, hypophysitis
• Infrequent (<5%)
• Pneumonitis
• Grade 3 or 4 toxicities are uncommon
Atkins MB et al. Clinical Care Options slideset 2014
CAR-T Therapy
 Chimeric antigen receptor (CAR) T cell therapy
 T cells are transduced with tumor specific CAR
 Process – blood drawn from patient
• T cells extracted using leukapheresis
• Transduction of T cells with retroviral vector
encoding CARs
• CAR-T cells reintroduced into patient – two daily
infusions
• “Warrior” T cells seek out & destroy enemy cancer
cells
Purwar R. Engineered T cells slideset 2016., Park JH. Conference Correspondent.ASH 2015 abstract 682.
CAR-T Therapy
 Advantages
• Fast & high response rates – 91% CR pediatric ALL; 82%
CR adult ALL
• No HLA typing needed (like with allogeneic HSCT)
• Side effects less harmful than chemo or allo HSCT
• Potential to target many antigens (protein,
carbohydrate, lipids)
• Cut cost by at least 30% compared to allo HSCT
 Challenges
• Cytokine syndrome – treat with steroids
• Heavily pretreated patients may not have enough T
cells
• Long-term sequelae & relapse rates currently
unknown
Purwar R. Engineered T cells slideset 2016., Park JH. Conference Correspondent.ASH 2015 abstract 682.
Immunovirus
 Therapeutic vaccine – different from prophylactic vaccines
 Tumors & viruses have dynamic interactions
• Malignancy can suppress normal antiviral responses
• Many viruses preferentially infect cancer cells
• Viral infection can ravage a tumor while leaving adjacent healthy
cells untouched
 Two mechanisms
• Modified virus can induce tumor cell lysis through replication
within tumor cells
• Virus can activate T cell response against tumor antigens through
dendritic cells
• Injected directly into tumors, but showing effect on cancer
elsewhere in the body
Ledford H. Nature 2015;526:622., Pietrangelo A. Heathline News 2015 www.healthline.com
Immunovirus: Talimogene
laherparepvec (Imlygic®)
 First oncolytic viral therapy approved in the U.S.
 FDA (Oct 27, 2015) – local treatment of unresectable cutaneous,
subQ, & nodal lesions in pts with melanoma recurrent after initial
surgery
 Genetically modified herpes simplex virus – replicates in tumors &
produces GM-CSF
• Causes cell lysis – releases tumor-derived antigens & GM-CSF
• Elicits further antitumor immune response
 OPTiM trial – phase III multicenter, open label, randomized
• 436 advanced melanoma patients; Imlygic® vs GM-CSF
• Extended survival by 4.4 months; time to response 4.1 months
• SE – fatigue, chills, fever, nausea, flu-like symptoms, injection site
pain, cellulitis
 Being studied in combination with PD-1 inhibitors in melanoma &
other solid tumors
Talmogene laherparepvec package insert www.imlygic.com
Immunovirus: PVS-RIPO
 PVS-RIPO – genetically engineered poliovirus against GBM
• Genetic code of rhinovirus spliced into polivirus to remove it’s
disease-causing ablility
• Safety – in primates & humans; no nerve cell damage, no ability to
cause poliomyelitis, no ability for PVS-RIPO to change back to wild
type poliovirus
 Infused directly into patient’s tumor
• Catheter placed into tumor, 2.5ml PVS-RIPO infused in the ICU over
6.5 hours, catheter removed, patient followed, no further treatment
 Kills tumor cells & recruits immune response vs. the tumor
 SE – fever, flu-like, diarrhea, headache, N/V, limb weakness, breathing
difficulties, brain swelling, etc
 Future – phase II/III in adults, pediatric brain tumors, other tumor types
(showing response in lung, breast, colon, liver, pancreas, kidney, etc)
Gromeier M, et al. 2016 www.cancer.duke.edu
Immunovirus: What’s Next
 Other promising virus therapies
• Breast cancer vaccine – targets HER-2 neu receptor
• CimaVax-EGF – lung cancer vaccine developed in Cuba
• Respiratory enteric orphan virus (Reolysin®)
• Ovarian cancer vaccine (>80% of patients have metastatic disease)
• Trials ongoing in lung, colon, melanoma, sarcoma, head & neck
 Room for improvement
• Need a way to deliver the vaccine systemically
• Requires a technique to prevent an immune attack to the virus
prematurely
 Many viruses being studied
• Vesicular stomatitis virus that infects cattle but not humans
• Virus that hitch-hikes on certain blood cells camouflaged from immune
system
Cohn D. Innovations in Science 2015. www.standup2cancer.org
Chen DS, et al. Immunity. 2013;39:1-10.
Immunotherapy for the Future
 BiTE Anitbodies
• Bridges a target antigen on surface of cancer cell to CD3+ on the
cytotoxic T lymphocyte
• Engages T cell, bypassing MHC Ag-dependent activation of T cell
• T cells release proteolytic enzymes that lyse the tumor cell
• BiTE Ab then moves through bloodstream targeting other cells
• Activated T cells remain active
 Universal cancer biomarker???
• DNA methylation mark around ZNF 154 found in 15 tumor types
in 13 different organs
• Tumors often shed DNA into bloodstream
• Advantage – no prior knowledge of the cancer required
• Could be used to diagnose cancer earlier, monitor during
treatment, or identify high risk patients
BiTE antibodies www.amgenoncology.com, News release NIH 2016 Feb www.nih.gov
Currin R. CurrinBIOTECH Newsletter. 2011;1(10)
Immunotherapy for the Future
 TMEM (tumor microenvironment of metastasis)
•
•
•
•
Research has uncovered how breast cancer spreads
TMEM - 3 specific cells coming together
Tumors with high TMEM score are more likely to spread
New drug target – could lead to treatments to stop cancer from
spreading
 Magic wands
• Hand held probe connected to a laser that shines light onto
human tissue
• Can distinguish cancer cells from normal cells
• Neurosurgeons testing on brain tumor patients during surgery
• Trials showing the probe detects cancer cells when they are there
95/100 times
Pietrangelo A. Heathline News 2015 www.healthline.com, UC Davis Comprehensive Cancer Center 2016 www.ucdavis.edu
Immunotherapy for the Future
 IDH2 Inhibitors
• IDH2 mutations have been identified in many solid tumors &
hematologic malignancies
• 15% of AML patients – unlikely to respond to other treatments;
majority in the study had relapsed or refractory disease
• IDH2 inhibitor (AG-221) – pill taken daily for AML ; ORR 56% (24 of 45
patients) with 15 CRs
• Allows AML cells to develop into healthy neutrophils
• SE – mostly disease-related rather than treatment-related
 Proteomics
• Assessing proteins in the blood for cancer screening
• Research ongoing in ovarian cancer, oral cancers, & lung cancer
 Intraoperative radiation
• Single shot of radiation during surgery
• Less SE & improved outcomes
Mulcahy N. Medscape 2014 www.medscape.com, Crane K. US News 2014 www.health.usnews.com
Immunotherapy for the Future
 CRISPR technology
• Clustered regularly interspaced short palindromic repeats
• Gene editing technique used to inactivate genes & see what happens
• Can reveal which human genes are essential & which matter
specifically to cancer cells
• Humans have 20,000 – 25,000 genes – between 1600 & 1800 of
these are essential & less likely to carry mutations
• Essential genes in cell lines of 8 different cancers have been
catalogued so far
• Goal – find genes that are expendable in healthy cells but crucial in
tumors
• Not yet sure if we will find enough genes that differentiate cancer
cells or if they will be targetable
• Project Achilles – initiative that will use CRISPR to search for specific
weaknesses in over 500 cancer cell lines
