Cyramza® (ramucirumab): Gastric Cancer - GI perforering och tidigare kirurgi

Risken för gastrointestinal perforering i patientgruppen som tidigare genomgått kirurgi i REGARD och RAINBOW är inte känd.

Gastrointestinal Perforations

The incidence of grade ≥3 GI perforations among patients in the REGARD and RAINBOW studies is summarized in Table 1.

Abbreviation: GI = gastrointestinal. 

The specific risk of hemorrhagic perforation in the population of patients who had prior surgery is not known because this was not a stratification factor in either trial; however, additional details regarding location of GI perforation and prior surgery are summarized below.1-3

REGARD Study

In the REGARD study, 2 GI perforation events were observed in patients who received ramucirumab: 1 colon perforation and 1 intestinal perforation. One patient in the placebo arm experienced a colon perforation. All 3 of these events were fatal and investigators assessed the events as probably or definitely related to study treatment.1 

Of these 3 patients, only 1 patient received prior tumor-related surgery. The patient who received ramucirumab and placebo and experienced an intestinal perforation had received a prior gastrectomy.1 

RAINBOW Study

In the RAINBOW study, 4 GI perforation events were observed in patients who received ramucirumab plus paclitaxel

  • GI perforation (grade 3)

  • GI perforation (grade 5)

  • diverticular perforation (grade 4), and

  • intestinal perforation (grade 4).1

Of these 4 patients, only 1 received prior tumor-related surgery. The patient who received ramucirumab and paclitaxel and experienced a grade 3 GI perforation had received prior gastrojejunostomy.1

Study Designs

REGARD Study

The REGARD trial was a phase 3, multicenter, randomized, double-blind, placebo-controlled trial in patients with metastatic or locally advanced gastric or GEJ adenocarcinoma treated previously with fluoropyrimidine- or platinum-based combination therapy with an ECOG PS of 0 or 1. Patients were randomly assigned in a 2:1 ratio (stratified by weight loss, region, and location of the primary tumor) to receive ramucirumab (8 mg/kg every 2 weeks) plus BSC (n=238) or placebo (every 2 weeks) plus BSC (n=117) until disease progression, unacceptable toxicity, withdrawal, or death.3

RAINBOW Study

The RAINBOW trial was a phase 3, multicenter, randomized, double-blind, placebo-controlled trial in patients with metastatic or locally advanced nonresectable gastric or GEJ adenocarcinoma following disease progression during or within 4 months after last dose of first-line platinum plus fluoropyrimidine combination chemotherapy with or without an anthracycline and an ECOG PS of 0 or 1. Patients were randomly assigned in a 1:1 ratio (stratified by region, measurable vs nonmeasurable disease, and TTP on first-line therapy) to receive ramucirumab (8 mg/kg days 1 and 15) plus paclitaxel (80 mg/m2 days 1, 8, and 15) (n=330) or placebo (days 1 and 15) plus paclitaxel (80 mg/m2 days 1, 8, and 15) (n=335) of a 28-day cycle until disease progression, unacceptable toxicity, withdrawal, or death.2
