Cancer Statistics
In the U.S., 1 of every 2 men and 1 of every 3 women in will receive a
cancer diagnosis in their lifetime
Cancer is the #2 cause of death in the United States
• Projected to surpass heart disease as #1 in the next decade
Cancer is the #1 cause of death in Idaho
Cancer is the #1 cause of death by disease in children
• Every 3 minutes, somewhere in the world, a child is diagnosed with
cancer
There are now >14 million cancer survivors in the U.S.
• 5-year survival for all cancers is >68% (2004-2010) up from 49% in
the late 1970s
The FDA approved 18 new cancer drugs in 2015 compared to 6 in 2010
Currently 800 ongoing clinical trials for new cancer immunotherapy
drugs; only 5% of cancer patients participate in clinical trials
Cancer spending is roughly 5% of the total spent on medical care in the
U.S in general

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)

IPILIMUMAB
NIVOLUMAB
PEMBROLIZUMAB
Drake CG et al. Nat Rev Clin Onc. 2014;11:24-37.
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

combination with ipilimumab
• NSCLC – metastatic; with progression on or after platinum-based
chemotherapy and EGFR or ALK therapy if EGFR or ALK positive
• Renal Cell – advanced disease who have received 1 or 2 prior
therapies
Summary – ORR in patients with advanced NSCLC, melanoma,
renal cell carcinoma
•
•
•
•
•
65 of 306 patients had ORR (CR or PR)
30 of those 65 (46%) had response evident at first tumor eval (8wks)
42 of those 65 (65%) had response lasting >1yr
35 of those 65 (54%) had response ongoing at time of data analysis
Response persisted off the drug
Nivolumab pkg insert www.opdivo.com, Atkins MB et al. Clinical Care Options slideset 2014.
Immunotherapy: PD-1 inhibitors
Nivolumab in Hodgkin’s Lymphoma
• Phase I – 23 patients who failed >3 previous regimens
including brentuximab vedotin and HSCT
• ORR 87% (20/23 patients) w/ CR in 4 (17%) with 40-wk
follow-up
• No life threatening toxicities or treatment deaths
Activity in breast, ovarian, colon, bladder, hepatic, gastric,
head & neck, pancreatic, GBM, lymphomas, & many others
Multiple combinations being studied (ie: with vaccines &
with other targeted drugs)
Nivolumab package insert www.opdivo.com, Mulcahy N. Medscape.2014. Abstr 289 & 290.
Immunotherapy: PD-1 inhibitors
Pembrolizumab (Keytruda®) – FDA approval
• Melanoma – unresectable or metastatic
• NSCLC – metastatic; with progression on or after
platinum-based chemotherapy and EGFR or ALK therapy
if EGFR or ALK positive
• Activity in SCLC, esophageal, breast, ovarian, head &
neck, pancreatic, lymphomas, & many others
Former President Jimmy Carter

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

Conclusions
Cancer will soon be the #1 cause of death in the United States
Cancer treatment is entering a new era – stimulating the
patient’s own immune system to fight cancer
Immune checkpoint inhibitors have demonstrated success in
treating cancer patients with advanced disease
CAR-T therapy is an exciting new way to target the immune
system & may eventually replace allogeneic HSCT
Immunoviruses are being used in innovative ways to treat
cancer with some promising long-term results
Technology will change how cancer is prevented, detected,
and treated in amazing new ways
Today’s patient cases illustrate how technology & innovations
are providing new hope for cancer patients & their loved ones
