ECOG 3598: Rationale for Thalidomide
Diverse Properties
• Anti-angiogenic
– Inhibits expression of a number of angiogenic
cytokines: VEGF, bFGF, COX2, TGF beta
expression
• Immunomodulatory
– T cell/NK stimulation
p y
– Induces expression of immunomodulatory
cytokines (IL-12, gamma IFN)
• Anti-proliferative

Conclusions
• Thalidomide did not improve the survival of
patients with locally advanced NSCLC when
administered with carbo/paclitaxel
• Thalidomide was associated with increased
thrombotic events, despite the addition of
low-dose aspirin.
• Lack of efficacy did not appear to be due to
inadequate thalidomide dosing, as patients
were titrated to their maximum tolerated
dose.
• Identifying effective anti-angiogenic drugs for
challenging
NSCLC is challenging.

Summary
Administration f t d b l ti
• Ad i i t ti of pemetrexed, carboplatin and d
thoracic radiation with or without cetuximab produced
a median survival of 22 months.
• Both regimens met the pre-defined threshold (median
survival of 20.9 months) to be considered worthy for
development
further development.
• Trends toward better outcomes observed with non-
q
squamous NSCLC in this study. y
• Toxicities related to concurrent chemoradiation are
similar to previous studies

Summary
• EGFR mutation status
– In mutation positive patients, PFS was significantly longer with
gefitinib than with carboplatin/paclitaxel
– In EGFR mutation negative patients, PFS was significantly
shorter with gefitinib than with carboplatin/paclitaxel
EGFR-gene-copy number
• EGFR b
– A possibly related trend in PFS was observed. Post hoc
explorations suggest this effect was driven by the overlap of
high EGFR-gene-copy number with a positive EGFR mutation
status
• EGFR protein expression
– This was found to be less of a differentiator between the two
treatment arms in terms of PFS
• ORR results were consistent with PFS results

RR – 19% vs 8% favoring Pem + vandetinib ( 0 001)
• Delayed time to symptom progression (HR=0.61,
p=0.004)
p 0.004)
• No difference in overall survival
• Conclusion: Negative trial but largely consistent with the
ZODIAC results
• Issue: Inclusion of squamous cell carcinoma (21%)

• 1240 2nd+ line pts randomized to erlotinib vs vandetinib
• Primary endpoint – PFS (superiority)
• PFS HR – 0.98, p=0.7
• l ti b d ti ib (p=ns)
RR – 12% vs 12% erlotinb vs vandetinib ( )
• Vandetinib was more toxic (diarrhea, QTc interval,
overall incidence of > grade 3 AEs)
• No difference in overall survival; planned non-inferiority
test for PFS and OS showed vandetinib was “not
inferior” l i ib
i f i ” to erlotinib
• Conclusion: Negative superiority trial; positive non-
inferiority trial (secondary)
