Outline

• Review the concept and evolution of immunotherapy in the treatment of cancer

• Discuss current immunotherapeutic approaches involving checkpoint inhibitions in the treatment of NSCLC

• Discuss additional immunotherapeutic approaches being evaluated in the treatment of NSCLC

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!

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?

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?

• 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

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
