•Pfizer Confidential
13
What We Look for: Key Attributes of Successful Programs
Essentials
– Targetable with a biologic
• Primarily monoclonal antibodies, peptides, proteins
– Novel mechanism addressing unmet medical need
– Strong link of pathway to human disease
Differentiators
– Ability to streamline path to proof-of-mechanism in humans
– Translating basic biological research into the clinic
• Connection of basic scientific researcher & clinical investigator
• Clinical differentiation opportunity via patient stratification,
molecular signatures, genetic associations, biomarkers
•Pfizer Confidential
14
Target Discovery
What Makes a Good Target?
Compelling validation of target/pathway
Target identification often comes from an association of target with
disease (e.g. expression pattern) and validation is the process of
defining the functional consequence (e.g. siRNA KD, KO mouse)
Considerations for defining an attractive target
– Link of mechanism to disease
– Target validation/biological evidence
• Evidence of translation to human disease
– Potential safety liabilities associated with target modulation
– Technical feasibility (e.g. druggability)

Focused on Monoclonal Antibodies
Antibody Modes of Action
Neutralizing Antagonist
– Antibodies that bind to a target and block an interaction
Agonist
– Antibodies that bind to a receptor and stimulate a downstream
process
Effector Function (Cell killing mechanisms)
– ADCC: Antibody-Dependent Cell-Mediated Cytotoxicity
•
Recruits macrophages, monocytes, or NK cells
– CDC: Complement-Dependent Cytotoxicity
•
Recruits complement serum proteins
•Pfizer Confidential
18
Additional Modes of Action in the CTI portfolio
Antibody Drug Conjugate (ADC)
– Antibody linked to a toxic drug via a linker; method to deliver into
specific cell types
Fc Fusion
– Used to extend half-life of peptides and/or small proteins
Peptide or Protein
– Often requires modification to become drug-like

CTI Case Study: Humanized Antibody Program
Background:




Cell surface antigen target up-regulated on tumor cells
Antigen expressed on few normal tissues
Target not down-regulated upon antibody binding
Mabs in hand
 Aim: To generate a humanized mAb with the following modes of action:
 Antibody effector function: ADCC/CDC
 Potential opportunity to generate an ADC (antibody drug conjugate) given
selective expression on tumor cells
POM trial:
(1) Incorporate patient stratification to enhance POM measures (e.g. IHC, mutation status)
(2) Measurable endpoints in line with pre-clinical activity
 Measurable biomarker deposition in tumor biopsies (CDC)
 Demonstrate increase in tumor necrosis and presence of immune infiltrate in post-treatment
biopsies (ADCC/CDC)
(3). CT scans to monitor tumor regression
•Pfizer Confidential
22
CTI Case Study: MOA via Target Modulation
Background:




Target antigen is a cell surface receptor located on cells in the blood and intestinal tissue
Genetic markers in the receptor are associated with Inflammatory Bowel Disease
These genetic markers define a “high risk” IBD population with elevated receptor levels
Dysregulation of pathway also occurs in this subset of patients
 Aim: To generate a mAb to block receptor activity and inhibit down-stream
signaling, reducing the inflammatory cascade in patients whose disease
is driven by this defined pathway
POM Trial:
(1) Use genetically defined “high risk” and “low risk” patient subgroups for POM.
(2) Measurable endpoints in line with pre-clinical activity
.Evidence of inhibition of pathway activation in blood cells pre- and post-treatment.
 RNA signature in gut biopsies provides further evidence of reduced inflammatory cascade.
(3) Known measurements from serum and stool samples pre- and post treatment provide
additional mechanistic information.

New and more effective treatments that can induce and maintain remission
- Prevention of underlying dysregulation of B- and T- cells
- Modulation of innate immunity
- Targeting or interrupting inducers of persistent immune activation/inflammation
- Inhibition or modulation of inflammatory processes involved in flares (renal, synovial
or cutaneous)

function, apoptosis & proliferation, cardioprotection and neovascularization.
• - Novel mechanisms that impact endothelial repair (beyond standard of care) such
as plaque stabilization and dissolution, mast cell & macrophage regulation
• Defined patient populations at highest risk of CV events that would most benefit
most from this therapeutic approach is required
