Milestones in the Palliative Systemic Treatment of NSCLC
1990 2000 2010
Platinum based Chemotherapy (MIC, MVP)
Platinum +3rd Generation Agents
EGFR TKIs(unselected patients)
1st line EGFR TKIs(mutated patients)
Pemetrexed in Non-Squamous NSCLC
Maintenance therapies in NSCLC (Pemetrexed, Erlotinib, Docetaxel, Gemcitabine, Bevacizumab)
Ongoing development - Molecular profiling & development of therapies targeting the biological drivers of cancer:
• Overcoming resistance to EGFR TKI’s, next generation ALK inhibitors (ceritinib, alectinib, brigatenib, lorlatinib)
• NTRK, KRAS pathway (MEK, BRAF, MTOR), PI3K pathway, FGFR, ROS1, RET, HER2,etc
2015
Crizotinib(ALK+patients)
Immunotherapy(anti PD-1, PD-L1)
CrizotinibROS 1
What is Maintenance Therapy?
• Patients receive 1st line treatment for NSCLC (platinum doublet chemotherapy)
• Approximately 40% will progress whilst on treatment and may go on to
receive 2nd line treatment immediately
• Approximately 60% will not progress – what happens next?
Wait until Progression (Will patients be fit enough for
treatment at this point?)
Consider for 2nd line treatment

Percentage
The limitations of ‘watch and wait’
• In studies of NSCLC, around 50% of patients did not receive any second-line therapy
What Maintenance Therapy Will We Consider?
• “Continuation” of a first line drug or “switch” to a new drug
• Immediately after initial 1st line (chemo) therapy
• Providing response to initial therapy is stable disease or
better and PS remains good (0-1)
– Pemetrexed, erlotinib, docetaxel, gemcitabine, bevacizumab
• Excluding:
– EGFR and ALK directed therapy
– Immunotherapy
– Continuing therapy after 2nd line chemo eg nintedanib, ramicirumab

What questions JMEN and PARAMOUNT do not answer
• How does 6 cycles of cisplatin pemetrexed
compare to 4 plus maintenance?
• Is there a benefit to continuing pemetrexed
maintenance after carboplatin pemetrexed?
• Norwegian lung cancer study group – 1st line pemetrexed carboplatin vs gemcitabine carboplatin* – n=427, 4 cycles, PS 0-2, 1EP HRQoL– No difference in HRQoL– OS 7.3 vs 7.0 months
*Groeberg et al, JCO 27:3217-3224, 2009
Pemetrexed Maintenance: Audit of practice
• Retrospective audit from April 2014 - April 2016. • N = 32, PS 0-1, 80%/20% PR/SD to Cisplatin Pemetrexed• Patients received a median of 6 cycles of Pemetrexed (range 1 to 25 cycles), with 14 patients (43.8%) still
on treatment at the time of data analysis.• Majority of patients (n=15/18, 83.3%) discontinued treatment due to progression, and 3 patients stopped
due to Grade 3/4 toxicities• Most did not require dose reduction (n=28/32, 87.5%), and 7 patients (21.9%) required 1 to 2 dose delays. • Of the 18 patients who progressed, 44.4% proceeded to have second line systemic therapies

0502 phase III study
Perol et al. JCO 30: 3516-3524, 2012
Study aim
Two primary objectives – to determine whether maintenance
gemcitabine (Gem) is better than observation and whether sequential
erlotinib is better than observation. Primary endpoint: PFS from
randomisation by independent panel review. Secondary endpoints: OS,
safety of maintenance treatment, symptom control.

• Maintenance pemetrexed in combination with bevacizumab is associated
with improvement in PFS for patients who have had first line treatment with
Cisplatin+Pemetrexed and Bevacizumab
• Should the control arm been pemetrexed alone as there is more single
agent activity associated with this agent?

Summary
• Rapidly changing therapeutic environment with PD-L1 expression
now changing first line therapy – (patients now receiving PD-1/PD-
L1 inhibitors + chemo for up to 2 years)
• Maintenance treatment is an option for patients of good PS (0-1)
after 4 cycles of platinum doublet chemotherapy with stable
disease or better
• Needs discussion with patient:
o some patients want a break from treatment
o Increased toxicity burden, increased frequency of follow up
visits
• Clinically meaningful improvements in PFS and OS
• Options include:
o Pemetrexed switch or continuation for NS – NSCLC – most
robust data (££)
o Less robust evidence for gemcitabine (£)
o Evidence for docetaxel but toxicity is a barrier (£)
o Erlotinib no longer an option for patients without EGFR
activating mutations
o Continuation bevacizumab +/- pemetrexed (£££)
