A Randomized Phase II Study of Androgen Deprivation Versus Combined With IMC-A12 Versus Androgen Deprivation Alone for Patients With New Hormone-Sensitive Metastatic Prostate Cancer


PRIMARY OBJECTIVES:

I. To compare the undetectable PSA rate (PSA < 0.2 ng/mL) after seven cycles (28 weeks) of
protocol treatment between those randomized to a LHRH agonist and bicalutamide and those
randomized to a LHRH agonist, bicalutamide and IMC-A12.

Secondary I. To assess the safety and tolerability of the combination of IMC-A12 with a LHRH
agonist and bicalutamide.

II. To compare the proportion of men who do not achieve a PSA of < 4 ng/mL between the two
groups.

III. To assess the accuracy of the prognostic model of undetectable PSA that was developed
from SWOG-9346 using current trial data from each arm.

IV. To assess serum samples and peripheral blood mononuclear cells (PBMNC) for
pharmacodynamic activity with potential biomarkers for IMC-A12 (including, but not limited
to: IGF-I, free IGF-I, IGF-II, IGFBP2, IGFBP3, Growth Hormone, insulin and C-peptide)
obtained from optional blood specimens both before initiation of androgen deprivation
therapy and twelve weeks after initiation of combined therapy.

V. To determine baseline pre-treatment circulating tumor cell (CTC) quantities and response
to therapy (for those patients with detectable CTC levels ≥ 1) twelve weeks later.

VI. In the same subset of patients where CTC levels are obtained, determine baseline serum
levels of microRNAs to include but not limited to mi-141 both before initiation of androgen
deprivation therapy and twelve weeks after combined therapy.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive androgen deprivation therapy comprising oral bicalutamide once daily
on days 1-28 and either goserelin subcutaneously or leuprolide acetate intramuscularly every
1, 3, 4, 6, or 12 months. Patients also receive cixutumumab IV over 1 hour on days 1 and 15.
Treatment repeats every 28 days for 7 courses in the absence of disease progression or
unacceptable toxicity.

ARM II: Patients receive androgen deprivation therapy comprising bicalutamide and either
goserelin or leuprolide acetate as in arm I.

After completion of study therapy, patients are followed up every 6 months for 2 years and
then annually for 3 years.

leuprolide acetate or goserelin) must be willing to continue the LHRH agonist in
addition to bicalutamide during study treatment

immunotherapy, anti-sense agents, small molecules, or monoclonal antibodies) and
recovered

warfarin)
