BACKGROUND: Two strategies to interrogate the insulin growth factor 1 receptor
(IGF-1R) pathway were investigated: vertical inhibition with dalotuzumab and
MK-2206 or ridaforolimus to potentiate PI3K pathway targeting and horizontal
cross-talk inhibition with dalotuzumab and MK-0752 to exert effects against
cellular proliferation, angiogenesis, and stem cell propagation. METHODS: A phase
I, multi-cohort dose escalation study was conducted in patients with advanced
solid tumours. Patients received dalotuzumab (10?mg?kg(-1)) and escalating doses
of MK-2206 (90-200?mg) or escalating doses of dalotuzumab (7.5-10?mg?kg(-1)) and
MK-0752 (1800?mg) weekly. Upon maximum tolerated dose determination, patients
with low-RAS signature, high-IGF1 expression ovarian cancer were randomised to
dalotuzumab/MK-2206 versus dalotuzumab/ridaforolimus, whereas patients with high
IGF1/low IGF2 expression colorectal cancer received dalotuzumab/MK-0752. RESULTS:
A total of 47 patients were enrolled: 29 in part A (18 in the dalotuzumab/MK-2206
arm and 11 in the dalotuzumab/MK-0752 arm) and 18 in part B (6 in each arm).
Dose-limiting toxicities (DLTs) for dalotuzumab/MK-2206 included grade 4
neutropenia and grade 3 serum sickness-like reaction, maculopapular rash, and
gastrointestinal inflammation. For dalotuzumab/MK-0752, DLTs included grade 3
dehydration, rash, and diarrhoea. Seven patients remained on study for >4 cycles.
CONCLUSIONS: Dalotuzumab/MK-2206 and dalotuzumab/MK-0752 combinations were
tolerable. Further developments of prospectively validated predictive biomarkers
to aid in patient selection for anti-IGF-1R therapies are needed.
