National Lung Matrix Trial
A Multi-drug, genetic marker directed, non-comparative
multi-arm Phase II trial in NSCLC
9
Trial Design
•
•
•
•
•
•
A multi-arm non-randomised design, with treatment allocation
according to molecular phenotype
No ‘standard’ control arm
Each biomarker/drug arm will contain 30 + patients
Endpoints are principally objective response rate and duration of
response: progression free survival for some drugs
The study will be a national study open at all ECMCs
The study will be carried out under a single clinical trial protocol
and regulatory submission

NLMT – rationale for single arm design
Crizotinib, EML4-ALK and ROS fusion as exemplars – the bona
fide targeted therapy
Option for biomarker-specificity testing in biomarker negative
patients
Allows discrete bio-marker testing
Based on strong pre-clinical data (and/or clinical data) and the
appropriate implementation of those findings

Randomised precision medicine trials
in lung cancer

Assessing the benefits of the novel therapy rather
than potential prognostic effects of the biomarker

SAFIR 02 - objectives
PRIMARY OBJECTIVE :
To evaluate whether treatment with targeted agents guided by high
throughput molecular analyses (CGH array, next generation sequencing)
improves progression-free survival as compared to standard maintenance
therapy in patients with metastatic NSCLC.
SECONDARY OBJECTIVES :
To explore the efficacy (response rate, progression-free survival, overall
survival) of the individual targeted agents
To correlate molecular mechanisms in patients with the efficacy endpoints
(response rate,progression-free and overall survival)

Concluding remarks – the importance of sustainability and a
unique opportunity to collaborate
“Therefore, there is maybe a place for, at least, a European
project, supported by the EU, setting up a global platform with
adequate resources (informatics, mathematics, statisticians,
etc) able to fully combined and interpreted the data, taking into
account differences in design and drugs, but aiming to propose
a unique interpretation of generated knowledge as soon as it
becomes available?”
