Trial ID # NCT01091428
Phase I/II
Drug Class Cell Cycle Inhibitors: AURKA/B

Drugs in Trial Alisertib, Paclitaxel
Eligible Participant

Patients Enrolled

142, median 2 prior therapies

Therapy Setting


Study Design

Double Blind, Randomized


ORR, DoR, PFS, evaluated per RECIST


RP2D: Ali 40mg bid (days 1-3, 8-10, 15-17 of every 28 days) + weekly (days 1, 8, 15 of every 28 days) Pac 60mg/m2 (Pac single drug arm: weekly 80mg/m2)

Ali+Pac vs Pac:

ORR: 48 (7CR, 23PR, n=63) vs 37% (2CR, 18PR, n=54)
DoR: 6.0 vs 7.6 months
PFS: 7.6 (6.8-8.8, n=73) vs 5.1 months (4.0-7.2, n=69); HR: 0.75 (0.58-0.96, p=0.14)

Clinically Significant Adverse Events

Ali+Pac vs Pac:
Serious AE: overall (29 vs 4%)
Grade 3/4 AE: overall (86 vs 20%), neutropenia (77 vs 10%), febrile neutropenia (14 vs 0%), stomatitis (25 vs 0%), anemia (14 vs 3%)


Ali+Pac combination shows promising increase in PFS compared to Pac alone, with a manageable safety profile
