HyperAcute Cellular Immunotherapy
Highly Differentiated From Other Immunotherapies
 Technology derived from serendipitous observation in the clinic
that led to unexpected anti-tumor responses
 HyperAcute mechanism based on potent anti-αGal antibodies
that protect humans from zoonotic infection
 Metabolically active, whole-cell immunotherapy with multiple
antigens
 Does not require tissue from patient (allogeneic)
 Multi-faceted immune response: antibodies, T cells and
eosinophils

IMPRESS Trial
Algenpantucel-L Phase 3 Registration Trial
 Randomized two-arm study of immunotherapy added to standard
adjuvant treatment versus standard treatment alone
 722 patients with surgically removed cancers enrolled in 70+ U.S. sites
from May 2010 to September 2013
 Protocol under SPA with FDA, also orphan drug and fast track status
 Statistical method employed is a log rank analysis powered at 80% to
detect approximately a 20% difference in overall survival
 Algenpantucel-L given at high dose used in Phase 2 study (300 million
cells) for a longer treatment period: every two weeks for six months,
then monthly for an additional six months
 Stratified for nodal status, radiotherapy administration and CA19-9
 The characteristics of the patients enrolled in the IMPRESS study are
consistent with patient populations enrolled in previous U.S. multiinstitutional trials in pancreatic cancer
9
IMPRESS Trial
Data Analyses
 The study was fully enrolled in September 2013
 The second interim analysis showed an estimated median overall
survival of 28.5 months* from the time of randomization for both
cohorts blended together
 We estimate that overall survival in the control arm, even allowing for
advances in the SOC, should be in the low twenties following surgery
 These initial data from the Phase 3 trial have given us confidence to
proceed with commercialization plans
*Kaplan Meier analysis based estimate
10
PILLAR: Second Phase 3 Trial
Locally Advanced Pancreatic Cancer
 Launched October 2012 (FPI, Q113)
 Open label, two-arm, randomized study (n=280)
 FOLFIRINOX or nab-paclitaxel +/- algenpantucel-L
 Algenpantucel-L: 300 million cells Q2 weeks up to 18 doses
 Overall survival is the primary endpoint
 Includes borderline or locally advanced unresectable patients
 Enrollment expected to be completed in 2015
Positive results might more than double the treatable patient population

Indoleamine 2,3-Dioxygenase (IDO) Pathway
A Key Immune Checkpoint Target
Regulates Innate and Adaptive Immune Response
 Is counter-regulatory (induced by inflammation)
 Inhibits effector T cells, activates suppressive Tregs
 Can create peripheral tolerance de novo
Dominant Regulatory Role
 Maternal tolerance; autoimmune disorders; transplant tolerance
 Tumor-induced immunosuppression
Overexpressed in Cancer
 Within tumor cells to directly suppress T cells
 Within antigen-presenting cells resulting in peripheral tolerance to
tumor-associated antigens
IDO is central to immune escape

Phase 1a Study of the Safety, Pharmacokinetics & Pharmacodynamics
of GDC-0919 in Patients with Recurrent/Advanced Solid Tumors
Conclusions:
 Overall, well tolerated up to 800 mg BID on a 21/28 day cycle
 Best response was limited to stable disease (SD) in 7 of 17 patients
 Higher doses modulate plasma Kyn in a manner consistent with half-life of drug
 Single and multiple dose exposures from 50 to 800 mg increased in approximately
dose-proportional manner
 Evaluation of the PK/PD relationship is ongoing to identify the dose that will achieve
maximal inhibition of IDO
 No immune-related AEs evident, although a possible relationship between study
treatment and elevation of liver enzymes cannot be ruled out at this time
 Study continues to evaluate safety, PK, activity, and PD at a continuous dosing
schedule (BID 28/28 days) to enable greater flexibility in future dosing regimens
 Phase 1b combination of GDC-0919 with atezolizumab (PD-L1 inhibitor) ongoing

Improved anti-tumor immunity & efficacy upon combination of the
IDO1 inhibitor GDC- 0919 with α-PD-L1 blockade versus α-PD-L1
alone in preclinical studies
GDC-0919 favorably alters tumor microenvironment
GDC-0919 decreases blood and tumor kynurenine levels in the EMT6 model.
Balb/c mice were injected with EMT6 cells followed by treatment with α-PD-L1 alone (10 mg/kg,
2x/week), GDC-0919 alone (200 mg/kg twice daily), or a combination of the two. At 2 hrs post-lastdose, blood and tumors were assessed for kyn/trp.

Improved anti-tumor immunity & efficacy upon combination of the
IDO1 inhibitor GDC- 0919 with α-PD-L1 blockade versus α-PD-L1
alone in preclinical studies
Summary and Conclusions:
 In the clinic, peripheral blood testing of Kyn levels showed transiently decreasing
plasma Kyn beyond 95% CI, in a manner consistent with its PK profile; PK was
approximately dose proportional with a t1/2 ~ 12 hrs (Nayak et al.)
 Preclinically, GDC-0919 decreased plasma and tumor Kyn levels in tumor-bearing
mice in a dose-dependent manner
 A combination treatment of GDC-0919 with αPD-L1 in the EMT6 syngeneic model
resulted in improved anti-tumor activity compared with αPD-L1 alone
 EMT6 treatment of GDC-0919 in combination with αPD-L1 led to increased
CD8+/Treg ratio and increased serum levels of IFNγ consistent with a stronger
adaptive anti-tumor immune response
 GDC-0919 induces activation of intratumoral CD11b+F4/80+ macrophages as well
as CD11b+CD11c+ and CD103+CD11c+ DCs as single agent and in combination
 Phase 1b combination of GDC-0919 with atezolizumab (PD-L1 inhibitor) ongoing
