CYRAMZA® (ramucirumab) + erlotinib is the first and only FDA-approved 1L combination therapy for patients with EGFR mut+ mNSCLC1
RELAY: A global, multicenter, randomized, double-blind, placebo-controlled phase III trial of CYRAMZA + erlotinib vs placebo + erlotinib in previously untreated patients with EGFR mut+ mNSCLC1,2
![RELAY Trial Design data](/assets/images/relay_trial_design.png)
The following clinical study design is for the RELAY trial.
This global, multicenter, randomized, double-blind trial, placebo-controlled phase III trial was conducted in previously untreated patients with non-small cell lung cancer (NSCLC) who were positive for a mutation in epidermal growth factor receptor gene (EGFR mut+). Patients were included in the trial if they had an exon 21 (L858R) substitution or exon 19 deletion, an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1, no CNS metastases, and no known EGFR T790M mutations at baseline. Randomization was stratified by geographic region (East Asia versus other), gender, EGFR mutation (exon 21 substitution versus exon 19 deletion), and local EGFR testing method (therascreen® and cobas® versus other PCR and sequencing-based methods). Patients (N equals 449) were randomized (1 to 1). In one arm (n equals 224), patients received CYRAMZA 10 milligrams per kilogram once every 2 weeks by intravenous administration plus erlotinib 150 milligrams per day orally. In the other arm (n equals 225), patients received placebo once every 2 weeks plus erlotinib 150 milligrams per day orally. Treatment was administered until disease progression or unacceptable toxicity. The major efficacy outcome measure was progression-free survival (PFS) and the supportive efficacy outcome measures were overall survival (OS), overall response rate (ORR), and duration of response (DoR). ORR was defined as complete response (CR) plus partial response (PR). ORR did not include stable disease (SD).
* Stratification factors: Geographic region (East Asia vs other), gender, EGFR mutation (exon 21 substitution vs exon 19 deletion mutation), and local EGFR testing method (therascreen® and cobas® vs other PCR and sequencing-based methods).
ORR= CR + PR; ORR does not include SD.2
Prespecified analysis included, but was not limited to, evaluation of PFS outcomes by exon 21 and exon 19 mutations.2
SELECT IMPORTANT SAFETY INFORMATION
Impaired Wound Healing
- CYRAMZA has the potential to adversely affect wound healing. CYRAMZA has not been studied in patients with serious or non-healing wounds.
- Withhold CYRAMZA for 28 days prior to elective surgery. Do not administer CYRAMZA for at least 2 weeks following a major surgical procedure and until adequate wound healing. The safety of resumption of CYRAMZA after resolution of wound healing complications has not been established.
