Abstract
Purpose
Lenalidomide has synergistic anticancer effects when used with chemotherapy. We conducted a phase I study of lenalidomide in combination with FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) in patients with advanced cancer.
Methods
A “3 + 3” study design was used. Lenalidomide was given orally on days 1–14, oxaliplatin and leucovorin were given intravenously on day 1, and 5-fluorouracil was given as a continuous infusion on days 1–2. The dose escalation phase of the study was followed by an expansion phase. We assessed the maximum tolerated dose, dose-limiting toxicities, and response.
Results
Thirty-eight patients were treated [median age 53 years (range 31–76); male/female 20:18]. The most common diagnosis was colorectal cancer (CRC) (n = 30, 79 %). Overall, 132 cycles (median 2/patient) were administered. No dose-limiting toxicities were observed. The maximum tested dose (dose level 4) was used in the expansion phase. Grade 3/4 treatment-related toxicities (all reversible) were seen in 14 (37 %) patients and included neutropenia (n = 11), thrombocytopenia (n = 2), and fatigue (n = 2). There were no thrombotic events. Response was evaluable in 32 patients: 19 (59 %) had stable disease (SD), including SD ≥6 months in 4 (13 %) patients. Tumor types with SD ≥6 months were CRC (n = 2; progression-free survival [PFS] 11.3 and 7.1 months, respectively), gastric (n = 1; PFS 8.5 months), and pancreatic (n = 1; PFS 6.4 months) cancer. The median PFS and overall survival durations were 2.2 months (range <1.3–23) and 5.5 months (range <1.6–23), respectively.
Conclusions
Lenalidomide in combination with FOLFOX was well tolerated. Four patients had prolonged stable disease. This combination merits further investigation for selected patient populations.
