2 Personalized healthcare A cornerstone of the Genentech / Roche strategy Diagnostics Pharma Molecule 60% of pipeline programs are being developed with companion diagnostics Actemra (Systemic sclerosis) Venetoclax (R/R CLL 17p) Atezolizumab (NSCLC) ACE 910 (Hemophilia) Esbriet (IPF) Lucentis (DR) Atezolizumab (Bladder) Alectinib (ALK+ NSCLC) Gazyva (1L CLL) 4 out of 9 BTDs enabled by a Dx that identified patients most likely to benefit 2

3 Significant advances in cancer biology Multiple molecular subsets of disease HER2 BRAF PIK3CA AKT1 MAP2K1 ALK Fusions EGFR PD-L1 Expression Unknown KIF5B-RET ROS1 Fusions NRAS KRAS MET MET splice site 3

4 Molecular Information in oncology Combination of molecular and patient data will enable change in R&D and clinical practice Patients matched to clinical trials Smarter, more efficient R&D Database & Analytics interface Better patient care Treatment plan selected Molecular understanding of cancer Patient outcomes 4

5 Multiple capabilities required Comprehensive tumor analysis and longitudinal assessment Comprehensive tumor analysis Continuous monitoring over time DNA-mutation & CNVs mrnaexpression Proteinexpression Cell free tumor DNA Imaging Ex: EGFR, BRAF DNA Cell signatures, targets RNA PDL1, other CI targets Multiplex IHC Ex: EGFR, BRAF Blood DNA Ex: ImmunoPet Imaging 5

6 FMI R&D collaboration Our partnership with FMI is key to informing R&D by leveraging molecular information Comprehensive tumor analysis Continuous monitoring over time DNA-mutation & CNVs mrnaexpression Proteinexpression Cell free tumor DNA Imaging Ex: EGFR, BRAF DNA Cell signatures, targets RNA PDL1, other CI targets Multiplex IHC Ex: EGFR, BRAF Blood DNA Ex: ImmunoPet Imaging Molecular Information from FMI database and GNE/Roche clinical trials (FM1 & FM1 heme) Immunotherapy panel development (DNA & RNA) Development of a blood-based molecular assays 6

7 1 Roche / FMI database queries Example: PIK3CA mutations in multiple cancers Clinical trial data 50,000+ patient data in FMI database Roche database FMI clinical database 7

8 1 Implementation of FMI panels in development Focus on high-value clinical samples Clinical trial data 50,000+ patient data in FMI database Roche database FMI clinical database Current prioritization*: 1. Trials with post-progression biopsy (with archival baseline samples) 2. Phase 3 trial** n> Phase 2 trial* n> Phase 1b combos ** Positive trial, evidence of activity or potential identification of subset / high value for informing our pipeline (i.e., importance of disease setting / indication / treatment) 8

11 2 PD-L1 IHC: Staining for TCs and ICs Assay sensitivity critical in detecting both cell types Immune cells (ICs) Tumor cells (TCs) Tumor and immune cells (TCs and ICs) WCLC 2015 e.g. bladder 1 IMvigor 210 ECC 2015, 2 POPLAR ECC 2015 e.g. NSCLC 11

12 Overall Survival 2 Patient selection enriches for benefit PD-L1 selected lung (TC & IC) and bladder cancer (IC) Lung cancer: Survival hazard ratio* Bladder cancer: Overall survival* TC3 or IC3 TC2/3 or IC2/3 TC1/2/3 or IC1/2/3 TC0 and IC Median OS Not Reached (95% CI, 7.6-NE) ITT N= Hazard Ratio In favor of atezolizumab In favor of docetaxel IC2/3 IC0/1 + Censored 0 Median OS 6.7 mo (95% CI, ) Time (months) 12 * Monotherapy data ECC

13 Overall Survival Change in sum of longest diameters (SLD) from baseline (%) 2 Benefit is not the same for every patient Some patients with high expression of PD-L1 do not benefit why? Bladder cancer: Overall survival IC2/3 IC0/1 + Censored 0 Median OS 6.7 mo (95% CI, ) Median OS Not Reached (95% CI, 7.6-NE) Time (months) Why do these patients progress? Why do these patients respond? Time on study (days) Example: Atezolizumab phase 1 data in urothelial bladder cancer patients 13

14 Biomarkers for cancer immunotherapy Key platforms for discovery and development Many types of data will be needed to inform patient care including: Proteinexpression mrnaexpression DNA-mutation & CNVs Cell free tumor DNA Other Dx & patient data PDL1, other CI targets IHC Cell signatures, targets RNA Ex: EGFR, BRAF DNA Ex: EGFR, BRAF Blood DNA Ex: Imaging, outcomes etc EMRs PDL-1 IHC and multiplex IHC 1 2 Immune cell types and signatures Mutation burden & neo-epitope prediction 14
