Lung Cancer 2012 – Where We Are and Where We’re Heading

Strategies to Improve Outcome of Lung Cancer

Patients• Move away from approaching lung

cancer as one disease

• Develop treatment strategies for different subsets of lung cancer

• Treatment improvements based on – Histology– Oncogenic alterations

Scagliotti GV, et al. J Clin Oncol. 2008;26(21):3543-3551.

Cisplatin 75 mg/m2 day 1 plus Gemcitabine 1250 mg/m2 days 1 & 8

Randomization Factors

•Stage •Performance status

•Gender •Histologic vs cytologic diagnosis

•History of brain metastases

Cisplatin 75 mg/m2 day 1 plus Pemetrexed 500 mg/m2 day 1

Vitamin B12, folate, and dexamethasone given in both arms

Each cycle repeated q3 weeks up to 6 cycles

Zhou et al. Lancet Oncol 2011

Median progression-free survival

• Erlotinib (N = 82): 13.1 months

• Chemotherapy (N = 72): 4.6 months

– HR 0.16 (95% CI 0.10-0.26)

– Log-rank p < 0.0001

EGFR Kinase Inhibitors 2012• Clinical activity in EGFR mutant NSCLC 1,2

– 1st line response rate: 60%-80%– 1st line progression free survival 10–14 months

• Gefitinib and erlotinib superior to 1st line chemotherapy1,3

– Higher RR and longer PFS; no OS improvement– Better toxicity profile

• However – resistance develops in most if not all patients

Dacomitinib (PF299804) in ERBB2 amplified NSCLC

• Molecular analysis revealed a HER2-positive tumor

• Patient was commenced on dacomitinib in December 2008 and experienced a partial response after 4 weeks of 45 mg orally once daily with 21 days per cycle

• Of particular interest was a notable reduction in the patient's soluble extracellular domain HER2 levels (non-invasive method for tracking treatment efficacy)

Pre-clinical efficacy of neratinib and afatinib in ERBB2 mutant NSCLC

• The subset of NSCLC patients with tumors carrying the ERBB2 mutation may benefit from treatment with neratinib1

• The major lung cancer-derived mutants of ERBB2 are oncogenic and are associated with sensitivity to the irreversible EGFR/ERBB2 inhibitor neratinib2

• Clinical testing of afatinib/rapamycin in NSCLC patients with tumors expressing HER2 mutations is warranted3

– Pemetrexed– Bevacizumab

• Some KRAS and PIK3CA mutations• Ongoing systematic genomics efforts

FGFR1 Amplification in a Subset of Squamous Cell Cancers

Weiss J et al. Sci Transl Med 2010

"Focal FGFR1 amplification is common in squamous cell lung cancer and associated with tumor growth and survival, suggesting that FGFR inhibitors may be a viable therapeutic option in this cohort of patients."

FGFR1 Inhibitor is Effective in FGFR1 Amplified Cells

Weiss J et al. Sci Transl Med 2010

Phase I trial of BGJ398 (Pan FGFR inhibitor) is currently underway (NCT01004224)

DFCI Thoracic Program Genomics Initiative

• Aim to provide routine genotyping to all lung cancer patients

• EGFR 2004; KRAS 2008• Comprehensive July 2009

– Partly supported by philanthropy– EGFR, KRAS, BRAF, PIK3CA, ERBB2 & EML4-

ALK• > 900 patients genotyped to date

– 4 dedicated CRCs

DFCI Thoracic Program Genomics Initiative contd.

• Limited to “non-squamous cell” carcinoma– Squamous cell carcinoma to start 2012

• Failure rate ~10%– Insufficient tumor, bad quality DNA– Bone biopsies are bad for genotyping

• ~50% of the patients with known alterations have received a molecularly targeted therapy

Evolution of Lung Cancer Genotyping

• Current – sequencing based (6 genes)– Currently limited to lung cancer

• Mass spec based genotyping (Oncomap)– All cancers; started in 2011

• Whole exome sequencing in development– U01 grant

• Lung cancer and colorectal cancer

Lung Cancer 2012 – Where We Are and Where We’re Heading

• “One size fits all” era of treatment and drug development is over for lung cancer

• Two validated genomic targets– Mutant EGFR and ALK rearrangements– Ongoing - ? use in earlier disease & drug resistance

• Rapid pace of pre-clinical discoveries

• Goal to find and develop effective therapies for all subsets of NSCLC patients
