De-escalation Immunotherapy mAintenance Duration Trial for Stage IV Lung Cancer Patients With Disease Control After Chemo-immunotherapy Induction — DIAL  

Metastatic NSCLC Clinical Trial

Official title: A Phase II-III Randomized Trial Evaluating Maintenance Pembrolizumab (± Pemetrexed) Until Progression Versus Observation (± Pemetrexed) After 6 Months of Platinum-based Doublet Chemotherapy Plus Pembrolizumab Induction Treatment in Patients With Stage IV Non-Small Cell Lung Cancer (NSCLC)

Clinical Trial Summary

Immunotherapeutic approaches recently have demonstrated clinical efficacy in several cancer types, including melanoma and NSCLC. As a matter of fact, first registration trials of immune-checkpoints inhibitors (ICI) in second-line settings (pembrolizumab as well as nivolumab or atezolizumab) had stated that ICI could be continued until disease progression or not tolerable toxicity, up to 5 years. This is only for the first-line registration studies that the arbitrary maximal duration of treatment of 2 years was set up by the Companies sponsoring such trials.

The aim is to study a de-escalation scheme of treatment from 2 years of immunotherapy to 6 months (27-weeks), in patients with controlled disease.

Clinical Trial Description

This is a phase II-III randomized, open-labelled, multicentre study for NSCLC patients who are naive of treatment for advanced disease. Patients will be given first-line chemotherapy + pembrolizumab: platinum doublet for at least 3 cycles, either paclitaxel-carboplatin for patient with SCC or 3 cycles of pemetrexed-platinum salt followed by 2 cycles of pemetrexed and 6 cycles of pembrolizumab.

Only patients with disease control, confirmed at 6 months (27-weeks) without drug-related toxicity imposing treatment discontinuation will be randomized 1:1 either to continuation of pembrolizumab (± pemetrexed for non-SCC) until disease progression or unacceptable toxicity or 2 years, or observation (± pemetrexed for non-SCC).

Patients will be stratified by performance status (0 versus 1), histology (SCC versus non-SCC), PD-L1 (PD-L1 < 1% versus 49%≥PD-L1 ≥ 1% versus PD-L1>49%), sex and response at randomization (partial response versus stabilisation). ;
