Background

Ramucirumab, an anti-VEGFR2 monoclonal antibody, improved the outcome of MGC pts both as a single agent and in combination with paclitaxel, achieving recent approval in second-line therapy. However, few ”real life” data are available. The objective of the RAMoss study is to evaluate the safety and efficacy of ramucirumab in the Italian compassionate-use program, prior to marketing authorization.

Methods

The primary endpoint was safety and secondary were overall response rate (ORR), progression free-survival (PFS) and overall survival (OS). Pts received ramucirumab 8 mg/kg/iv every 2 weeks or in combination with paclitaxel 80 mg/m2/iv on days 1, 8, and 15 of a 28-days cycle until progression, death or unacceptable toxicity. Complete blood test were performed before each drug administration and disease was assessed every 2 cycles.

Results

109 pts were enrolled with the following characteristics: median age: 61 yrs; gastric site: 69,7%, cardias: 23,8%, distal oesophagus: 6,4%; PS ECOG: 0(56,8%) 1(34,8%) ≥2(8.2%); monotherapy : 12,9%, combination therapy: 87,1%; peritoneal metastasis: 41,2%. Median treatment duration was 3 mos(1-12 mos). The most frequent grade ≥ 3 AEs were: neutropenia (5.5%), asthenia (2.7%), hypertension (1.8%). Febrile neutropenia occurred in 0.9% of the pts. No bleeding of grade ≥ 2 was reported. There were no treatment-related deaths. ORR was 17,4%, 7.1% (monotherapy) and 18,9% (combination), respectively. Stable disease was observed in 30.2%; disease control rate (DCR) was 47,6%. With a median follow-up of 8.0 mos (95% CI: 6.5-9.5), median PFS was 3.0 mos (95% CI: 2.32-3.67), median OS was 7.0 mos (95% CI: 5.76-8.23). On a multivariate analysis, age 61 (HR 3.18, 95% CI: 1.8-5.6, p= 0.0001) and PS ECOG

Conclusions

Ramucirumab treatment, in a "real-life" setting, is proven to be well tolerated in an Italian cohort of pretreated MGC pts with no new safety signals.
