Cyramza® (ramucirumab): Patientrapporterade resultat i RELAY-studien

Tid till försämring av både LCSS och ASBI var liknande mellan behandlingsarmarna i RELAY-studien.

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

Assessment of Patient-Focused Outcomes

Assessment Interval

Patient-focused outcomes were evaluated using ECOG PS, LCSS, and EQ-5D-5L. ECOG PS was assessed at every visit and LCSS and EQ-5D-5L at

  • baseline

  • every other cycle, and

  • 30-day follow-up visit.2

ECOG PS Assessment

Time-to-deterioration in ECOG PS was

  • a prespecified exploratory endpoint

  • defined as the time from randomization to the first observation of ECOG PS ≥2, and

  • estimated with Kaplan-Meier and Cox regression.2

LCSS and EQ-5D-5L Assessment

Time-to-deterioration in LCSS was

  • prespecified secondary endpoint

  • defined as the time from date of randomization until the date of the first ≥15 mm increase from baseline, and

  • estimated with Kaplan-Meier and Cox regression.2

EQ-5D-5L mean scores were summarized by cycle/visit.2

Mean changes from baseline in EQ-5D-5L/LCSS scores were estimated using Mixed Effect Model Repeat Measurement regression by comparing with baseline scores.2

Patient-Reported Outcome Results

ECOG PS

The majority of patients in both arms maintained an ECOG PS of 0 or 1 until PD (92.4% in the ramucirumab plus erlotinib arm and 95.1% in the erlotinib plus placebo arm); therefore, TTD analysis was not feasible.2 

LCSS and 5Q-5D-5L

Overall patient compliance for LCSS and EQ-5D-5L completion was similar between treatment arms (LCSS: 95.7% in the ramucirumab plus erlotinib arm and 96.7% in the erlotinib plus placebo arm; EQ-5D-5L: 96.1% in the ramucirumab plus erlotinib arm and 96.6% in the erlotinib plus placebo arm). Time-to-deterioration of both LCSS and ASBI was similar between treatment arms (LCSS: HR=0.96, 95% CI: 0.69-1.34; ASBI: HR=1.01, 95% CI: 0.73-1.40). Hemoptysis was the only LCSS item that was different between arms and favored the erlotinib plus placebo arm (HR=1.99, 95% CI: 1.21-3.28).2 

The authors concluded that patient health-related QOL, as measured with the EQ-5D-5L, was not adversely impacted by the addition of ramucirumab to erlotinib.2
