Abstract 3568


In CORRECT, REG significantly improved overall survival and PFS vs placebo in pts with treatment-refractory mCRC. We did a retrospective, exploratory subgroup analysis of REG-treated pts in CORRECT with PFS >4 m (long PFS) and ≤4 m (short PFS).


Pts with pretreated mCRC were randomized 2:1 to REG 160 mg or placebo QD for 3 weeks on/1 week off until disease progression, death, or unacceptable toxicity. PFS was the time from randomization to progression or death. Of 505 pts randomized to REG, 98 (19%) had long PFS and 407 (81%) had short PFS.


Compared to short PFS pts, the long PFS group had a higher proportion of patients with ECOG PS0, 1–2 tumor sites, and ≥18 m since diagnosis of metastatic disease (Table). Long PFS pts received a median of 6 (1–12) cycles, short PFS pts a median of 2 (1–11). Mean actual daily doses were 138.7 mg (long PFS) and 149.2 mg (short PFS). Dose modifications occurred in 91% (long PFS) and 72% (short PFS). NCI-CTCAE (v3) grade (Gr) ≥3 REG-related treatment-emergent adverse events (TEAE) occurred in 64% (long PFS) and 53% (short PFS). Most common REG-related Gr ≥3 TEAEs included (long PFS, short PFS) hand–foot skin reaction (20%, 16%), hypertension (17%, 5%), fatigue (13%, 9%), diarrhea (16%, 5%), rash/desquamation (3%, 6%), and hypophosphatemia (5%, 3%). Gr ≥3 laboratory toxicities (long PFS, short PFS) included increased bilirubin (8%, 13%), ALT (6%, 5%), and AST (5%, 6%). Although REG-related TEAEs led to a higher dose modification rate in long PFS pts (71% vs 52% for short PFS), discontinuations due to REG-related TEAEs were similar (long PFS 5%; short PFS 9%).

Long PFS (n = 98) Short PFS (n = 407)
Median age, yrs (range) 61 (34–82) 61 (22–82)
Male, % 64 61
Median body mass index, kg/m2 25.6 24.7
ECOG PS, % 0 1 63 37 50 50
No. of tumor sites, % 1 2 3 ≥4 30 38 16 16 17 35 30 18
KRAS status, % mutant wildtype 47 44 56 40
Primary site of disease, % Colon Rectum Both 52 37 10 67 28 5
No. of prior regimens on or after diagnosis of metastatic disease, % 0–2 3 ≥4 22 22 55 28 25 47
Time since first diagnosis of metastatic disease to randomization, %


This exploratory analysis showed that pts with mCRC treated with REG who had PFS >4 m tended to have a better performance status, fewer metastatic tumor sites, and a longer time since diagnosis of metastatic disease, compared to pts with short PFS.
