Cyramza® (ramucirumab): Förekomst av pneumonit i RELAY

Study Design

The RELAY trial was a phase 3, global, multicenter, randomized, double-blind, placebo-controlled trial in patients (N=449) with previously untreated EGFR mutation-positive, metastatic NSCLC. All patients had an EGFR mutation of exon 19 deletion or exon 21 L858R and an ECOG PS of 0 or 1. Patients were randomly assigned in a 1:1 ratio (stratified by sex, region, EGFR status, and EGFR testing method) to receive treatment with erlotinib (150 mg/day) plus ramucirumab (10 mg/kg every 2 weeks; n=224) or placebo (10 mg/kg every 2 weeks; n=225) until disease progression or unacceptable toxicity.¹

Incidence of Pneumonitis/Interstitial Lung Disease

Treatment-emergent adverse events of pneumonitis and ILD are presented in Table 1.

Table 1. Treatment-Emergent Adverse Events of Pneumonitis and Interstitial Lung Disease in the Safety Population in RELAY^1,2

Abbreviations: EGFR = epidermal growth factor receptor; ILD = interstitial lung disease; n=number of patients; TEAE = treatment-emergent adverse events.

^a One patient in the placebo group had a fatal event of ILD more than 30 days after treatment discontinuation.

^b Data for ILD and pneumonitis are here because these are related and previously associated with EGFR tyrosine kinase inhibitors.

A similar proportion of Asian and non-Asian patients had ILD that included

• 9 (3%) of 344 Asian patients, and

• 2 (2%) of 102 non-Asian patients.¹

Due to the small sample size of patients who developed ILD/pneumonitis while on study, no specific efficacy analyses was performed for these patients.
