Agenda
 What’s the hype? – IO in the context of Cancer Therapy
 What do we know? – Scratching the surface of science
 What’s next? – Place your bets!
What's the Hype about?
Why talk about Immuno-Oncology?
 $$$: Rapid adoption, high revenue
projections for IO assets
 Science: Fundamentally new approach,
complementary to existing modalities
 Potential cure: Regaining the
status quo of „normal“
Immune Evasion is ONE key Mechanism of Cancer
Hallmarks of cancer
Active
invasion and
metastasis
Resisting
cell death
Angiogenesis
Sustained
proliferative
signaling
Hallmarks
of cancer
Replicative
immortality
Avoid
immune
destruction
Evasion
of growth
suppressors
As normal cells evolve into
a neoplastic state, they
acquire a combination of
antvantegous capabilities;
including the ability to avoid immune destruction

Cancerous cells are part of normal biology
Dynamic balance between cancerous cells and immune system
Elimination
Effective Surveillance
Equilibrium
Escape
Cancer Dormancy
Cancer Progression
• Effective antigen
processing/presentation
• Genetic instability
• Effective activation and
function of effector cells
• Immune selection
CD4+ T cell
CD8+
T cell
• Tumor heterogeneity
• Tumors can suppress, disrupt,
or “escape” the immune
system

IO in the Context of Cancer Therapy
Evolution and principles of cancer therapy
Genetic engineering etc.
– „Manipulate the scale“
Immuno-Oncology
– Elimination of „foreign“ (Immune Response)
Targeted therapy
– Slow the Escape (block tumor growth drivers)
Chemotherapy / Radiotherapie
– Slow the Escape (kill fast-growing / impaired repair)
Surgery
– Complete Elimination (before it spreads)

Immuno-Oncology – Where to start?
Basic steps of immune response
1. Education
 Recognition and
processing of
tumor-antigens
2. Activation
 Antigen presentation
 Selection and expansion
of specific effector cells
3. Targeted response
Tumor infiltration and
targeted killing
 Cytotoxic T-cells
 NK cells
+ B-cell mediated (mAbs)
+ Complement-supported

Other Trends in Cancer Therapy Development
For discussion!
 Study population - From orphan disease to individual therapy:
• Prior and subsequent therapies
• Combinations, combinations, ...
• Biomarker-based selection
 Clinical end points - How to get approved and reimbursed?
• Overall Survival -> Progression-Free Survival -> Cure Rate?
• “Marginal Benefit” within reasonable time frame and rapidly changing
Standard of Care / relevant comparator
• Conditional approval pathway evolution
 Taxonomy – What’s the indication?
• From primary tumor location and histochemistry of archival samples to real-time
genetic fingerprint (Next Generation Sequencing, circulating tumor cells and
circulating DNA/RNA)
