Biomarker Analysis
• Anti-PD-L1 antibody clone 22C3 (Merck) and a prototype IHC assay used to determine PD-L1 status/expression in contemporaneous biopsy samples
• PD-L1 positivity was defined as membranous staining in ≥1% of cells (neoplastic and intercalated mononuclear inflammatory cells)
• Membranous PD-L1 expression ≥50% selected as the cutoff on the basis of ease of use and ROC (receiver-operating-characteristic) analysis

Is Monotherapy Enough?
• ORR ranges from 15% to 24.8% for anti-PD-1/PD-L1 monotherapy in previously treated or untreated patients with NSCLC
• Depends on your expectations!
031
What Is the Right Partner for Combination?
• Chemotherapy?– Atezolizumab + platinum doublet untreated NSCLC: ORR of
67%1
– Nivolumab + platinum doublet shows similar efficacy with nivolumab monotherapy in untreated NSCLC (CheckMate-012)2
• Another checkpoint inhibitor (eg, ipilimumab)?– Nivolumab + ipi in 2nd-line NSCLC: 39% ORR3
• Targeted agent?– Nivolumab + erlotinib in erlotinib failure patients: 19% ORR4
• Tolerability (discontinuation due to treatment-related AEs)?– Nivolumab + platinum doublet: 21%2
– Nivolumab + erlotinib: 19%4

Differences Between Squamous and Non-Squamous Cancers?
• Biomarker not predictive in Squamous (017) but predictive in non-squamous (057)
– CheckMate057: Significant improvement in median OS but not median PFS– CheckMate017: Significant improvement in median OS and PFS
• Same drug, same biomarker
• Current/former smokers– CheckMate 017: 92%– CheckMate 057: 79.5%; EGFR/ALK in 17.5%
• Greater mutational load in 017 squamous cell cancers?• Immune system and squamous vs glandular epithelia?
• Does the immune status or immune microenvironment differ between these patients?
• Immune infiltrates in and around tumours differ
• Does the mutation burden make a difference? Are immunomodulatory mechanisms different?
• Are the cut offs correct? Are 1, 5 & 10% too low?
Kerr K. ASCO 2015. Discussant.
040
PD-L1 as a Potential Predictive Biomarker? (cont’d)
• Data are variable
• Rule in/Rule out– Biomarker to predict patient will benefit (and to what
degree)– Biomarker to predict patient will not benefit– 10% is easier than 5% is easier than 1%
• Assessment of immune cells– Relevance of immune cells present?– Cytology samples lack architecture
• Is a biomarker required?

041
PD-L1 as a Potential Predictive Biomarker? (cont’d)
• Is it the correct marker?
• Does the oncology community trust immunohistochemistry?
• Are our expectations of a biomarker in this setting reasonable?– PD-L1 is not ‘present’ or ‘absent’– Expression is biological continuum– Cut offs; definitions of positive are ‘artificial’

• Are our expectations of a biomarker in this setting reasonable?– PD-L1 is not ‘present’ or ‘absent’– Expression is biological continuum– Cut offs; definitions of positive are ‘artificial’– Immune Checkpoint inhibition is NOT like inhibiting an
addictive oncogene driver
• Four drugs, four different ‘biomarker tests’, all for ‘PD-L1’
Kerr K. ASCO 2015. Discussant.
043
Other Potential Biomarkers for Response?
• Other immune checkpoints
• Immune cells – Overall infiltrate– Specific cell types
• Immune gene signatures
• Mutational burden– Global burden– Mismatch repair genes (MMR)– Microsatellite instability (MSI)– Polymerase E (POLE) mutations– Smoking

MAGE-A3 and Adjuvant Therapy
• MAGE-A3 is an antigen that is expressed almost exclusively on the surface of tumour cells, including NSCLC1
– 17-50% of NSCLC expresses MAGE-A3– Expression is associated with poor prognosis
• Phase 2 trial in stage IB-II completely resected NSCLC: MAGE-A3 vaccine vs SOC2
– DFS: HR 0.76 (95% CI: 0.48-1.21)– OS: HR 0.81 (95% CI: 0.47-1.40)

BI 1361849*: Therapeutic mRNA-based Vaccine
• A novel investigational therapeutic mRNA-based vaccine developed in collaboration with CureVac
• Mobilises the patient’s own immune system to fight the tumour with a specific immune response
• Clinical investigation is underway in lung cancer settings
*This is an investigational compound and has not yet been approved. Its safety and efficacy have not yet been fully established.mRNA = messenger ribonucleic acid.

Summary/Conclusion
• Recent advances in molecular biology have “revived” and validated immunotherapeutic approaches for the treatment of cancer
• Anti-PD-L1mAb has significantly improved survival in patients with advanced or metastatic NSCLC
• However, there are still a number of issues associated with anti-PD-1/PD-L1 therapy, and it continues to be an active area of research and development
• Additional therapeutic approaches under clinical development include cancer vaccination
