Systemic therapy for non-oncogene addicted NSCLC
Disclosures
• Advisory Board: Astra-Zeneca, BMS, Boehringer Ingelheim, Lilly, Merck, Novartis, Pfizer, Roche, Taiho, Takeda, Yuhan
• Research grant: Astra-Zeneca, Boehringer Ingelheim
Systemic therapy in non-driver addicted NSCLC:
• First-line treatment of NSCLC without actionable oncogenic driver, with contraindications to use of immunotherapy
• 1st line management of non-squamous NSCLC
• Maintenance
• Anti-angiogenic agents
• EGFR inhibitors
• 1st line management of squamous NSCLC
General approach
• The treatment strategy should consider the histology, molecular pathology, age, PS, comorbidities and the patient’s preferences
• Systemic therapy should be offered to all stage IV patients with PS 0–2
In the beginning…line chemotherapy is better than BSC
NSCLC Meta-Analyses Collaborative Group. JCO 2008
2,714 patients,16 RCTs
Chemotherapy improves OS vs BSC: HR 0.77
One-year OS: 29% from 20%
ESMO guidelines:
Chemotherapy with platinum doublets should be considered in
all stage IV NSCLC patients without an actionable oncogenic
driver, without major comorbidities and
PS 0–2
Platinum-based doublets are the recommended chemotherapy
option in all stage IV NSCLC patients with no contraindications
to platinum compounds
Planchard ESMO guidelines 2019
• Which chemotherapy?• Platinum doublet with 3rd generation drugs (paclitaxel, gemcitabine, docetaxel,
vinorelbine) have comparable efficacy
• Cisplatin or carboplatin?• Cisplatin:
• higher ORR but paclitaxel or gemcitabine + a platinum agent in both arms had equivalent response.
• more nausea or vomiting
• Carboplatin: more thrombocytopenia and neurotoxicity
• Six cycles or fewer?• Six cycles: longer PFS, higher toxicity• Recommendation: 4 cycles +/- maintenance (I, A) and maximum of 6 cycles (I, B)
nab-Paclitaxel and Carboplatin : higher ORR, less neurotoxicity
Socinski JCO 2012
ESMO Guidelines:
Nab-paclitaxel combination can be considered an option in advanced NSCLC
patients, particularly in patients with:
1. greater risk of neurotoxicity
2. preexisting hypersensitivity to paclitaxel
3. or contraindications to standard paclitaxel premedication
1L treatment of advanced non-Squamous NSCLC without driver oncogenes (NSCC)
• Pemetrexed-based chemotherapy is preferred to gemcitabine- or docetaxel-based combinations in patients with non-squamous tumours
• Pemetrexed is restricted to NSCC in any line of treatment line
• Carboplatin and pemetrexed can be an option in patients with a contraindication to cisplatin
Planchard Ann Oncol 2018
Pemetrexed platinum and gemcitabine platinum have differential efficacy based on histology: JMDB
Cisplatin/ Pem superior in non-SCC Cisplatin/gemcitabine superior in SCC

Bevacizumab may be offered in the absence of contraindications
in eligible patients with advanced NSCC (bevacizumab should be
given until progression) [I, A]
Other issues with bevacizumab
• Can I combine it with another chemotherapy other than paclitaxel?
• Is CNS mets a contraindication?
Other issues with bevacizumab
• Can I combine it with another chemotherapy?• Bevacizumab might therefore be considered with platinum-based regimens
beyond paclitaxel/carboplatin in the absence of contraindications [II, B].
• Is CNS mets a contraindication?• Treatment with bevacizumab has also shown encouraging efficacy and
acceptable safety in patients with NSCC and asymptomatic, untreated brain metastases
• EMA removed label restriction on March 25, 2009, to allow patients with untreated CNS metastases to receive bevacizumab
Maintenance therapy
• Factors to be considered:
• Histology
• Residual toxicity after 1L chemotherapy
• Response to platinum doublet
• Performance status
• Patient preference
• Types of maintenance:
• Continuation maintenance :
• use of an agent that was included in 1L treatment
• Switch maintenance:
• introduction of a new agent after four cycles of platinum-based chemotherapy
Continuation maintenance therapy: pemetrexed after x4 cycles cisplatin/ pemetrexed (PARAMOUNT)
Paz-Ares Lancet Oncol 2012, JCO 2013
Improvement in PFS Improvement in OS
ESMO guidelines:
Continuing pemetrexed following completion of 4 cycles of first-line
cisplatin/pemetrexed ChT is, therefore, recommended in patients with
NSCC, in the absence of progression after first-line ChT and upon
recovery from toxicities from the previous treatment [I, A].
Switch maintenance therapy: pemetrexed after x4 cycles platinum based chemotherapy (JMEN).

Docetaxel standard 2nd line therapy until recently• Combination chemo has no OS benefit
over single-agent.
• Docetaxel: • Improvement in OS vs BSC • Similar efficacy, but more favourable
tolerability for weekly docetaxel schedule
• Pemetrexed:• Comparable OS to docetaxel• Lower rates of neutropenia, alopecia and GI
toxicity
• Docetaxel + antiangiogenic therapy• LUME Lung 1• REVEL• ULTIMATE
• Immune checkpoint inhibitors

• Carboplatin based doublet, monotherapy
• Maintenance erlotinib not recommended for WT EGFR
• Squamous NSCLC
• Platinum-based doublets with a third-generation cytotoxic agent (gemcitabine, vinorelbine, taxanes) for PS 0-2
• Identifying biomarkers in oncogene WT NSCLC
