Abstract
Background
Ramucirumab—alone or combined with paclitaxel—represents one of the main options for patients failing first-line treatment for advanced gastric cancer.
Objective
The RAMoss study aimed to evaluate the safety and efficacy profile of ramucirumab in the “real-life setting”.
Patients and Methods
Patients from 25 Italian hospitals started therapy consisting of ramucirumab 8 mg/kg i.v. d1,15q28 with or without paclitaxel 80 mg/m2 i.v. d1,8,15q28. The primary endpoint was safety, and secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS).
Results
One hundred sixty-seven patients with disease progression on first-line therapy received ramucirumab as monotherapy (10%) or combined with paclitaxel (90%). Median treatment duration was 4 months (1–17 months). Global incidence of grade (G) 3–4 toxicity was 9.6%, and for neutropenia 5.4%; treatment was discontinued due to toxicity in 3% of patients. The most frequent adverse events (AE) were G1–2 fatigue (27.5%), G1–2 neuropathy (26.3%), and G1–2 neutropenia (14.9%). ORR was 20.2%. Stable disease was observed in 39.2% of patients, with a disease control rate of 59.4%. With a median follow-up of 11 months, median PFS was 4.3 months (95% confidence interval [CI] 4.1–4.7), whereas median OS was 8.0 months (95% CI: 7.09–8.9). In a multivariate analysis, ECOG performance status <1 or ≥1 (HR 1.13, 95% CI 1.0–1.27, p = 0.04) and the presence versus absence of peritoneal metastases (HR 1.57, 95% CI 1.63–2.39, p = 0.03) were independent poor prognostic factors.
Conclusions
These “real-life” efficacy data on ramucirumab treatment are in line with previous randomized trials. Ramucirumab is well tolerated in daily clinical practice.
