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).

• Non-squamous NSCLC:

• Doublet chemotherapy ± bevacizumab

• 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
