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

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

The limitations of ‘watch and wait’

• In studies of NSCLC, around 50% of patients did not receive any second-line therapy

Page 6: Maintenance Treatment for Advanced NSCLC · What is Maintenance Therapy? • Patients receive 1 st line treatment for NSCLC (platinum doublet chemotherapy) • Approximately 40% will

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

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 (£££)
