CYRAMZA + erlotinib helped patients with EGFR mut+ mNSCLC reach more than 19 months median PFS1

Progression-free survival (PFS) was a major outcome measure of the RELAY trial. The following PFS results for epidermal growth factor receptor gene mutant (EGFR mut+) metastatic non-small cell lung cancer (mNSCLC) patients are presented in a Kaplan-Meier curve. With CYRAMZA plus erlotinib in the intent-to-treat (ITT) population (n equals 224), median PFS was 19.4 months with a 95 percent confidence interval of 15.4 to 21.6 months. With placebo plus erlotinib in the ITT population (n equals 225), median PFS was 12.4 months with a 95 percent confidence interval of 11.0 to 13.5 months. The hazard ratio was 0.59 with a 95 percent confidence interval of 0.46 to 0.76 and a P value less than 0.0001.
- The percentage of events at the time of analysis was 55% (122 patients) and 70% (158 patients) in the CYRAMZA + erlotinib and placebo + erlotinib treatment arms, respectively1
- 4 of 122 events in CYRAMZA-treated patients and 1 of 158 events in placebo-treated patients were deaths1
- The major efficacy outcome measure was PFS as assessed by the investigator RECIST v1.11
28.1% of patients treated with CYRAMZA + erlotinib and 49.3% of those treated with placebo + erlotinib had their disease progress at 1 year2
The RELAY trial evaluated the efficacy and safety of CYRAMZA + erlotinib vs placebo + erlotinib in previously untreated patients with EGFR mut+ mNSCLC. Major outcome measure was PFS. Supportive outcome measures included OS, ORR, and DoR. Patients were stratified by EGFR mutation status (exon 21 vs exon 19), geographic region (East Asia vs other), gender, and local EGFR testing method (therascreen® and cobas® vs other PCR and sequencing-based methods). All patients were required to have ECOG PS 0 or 1. Patients were randomized 1:1 to receive CYRAMZA 10 mg/kg (n=224) or placebo (n=225) every 2 weeks + erlotinib 150 mg/day.1,3
ORR=CR+PR; ORR does not include SD.3.
For patients on CYRAMZA + erlotinib who had a response, the median DoR was 18.0 months with CYRAMZA + erlotinib vs 11.1 months with placebo + erlotinib1,3

Duration of a response (DoR) was a supportive outcome measure of the RELAY trial. The following results are presented.
With CYRAMZA plus erlotinib (n equals 171), median DoR was 18.0 months with a 95 percent confidence interval of 13.9 to 19.8 months. With placebo plus erlotinib (n equals 168), median DoR was 11.1 months with a 95 percent confidence interval of 9.7 to 12.3 months. The unstratified hazard ratio was 0.62 with a 95 percent confidence interval of 0.48 to 0.81.
- The percentage of events at the time of analysis was 59% (101 patients) and 76% (128 patients) in the CYRAMZA + erlotinib and placebo + erlotinib treatment arms, respectively3
DoR was a prespecified secondary efficacy endpoint. DoR was not powered or controlled for type 1 error, and treatment differences observed cannot be regarded as statistically significant.

Arterial Thromboembolic Events (ATEs)
- Serious, sometimes fatal, ATEs, including myocardial infarction, cardiac arrest, cerebrovascular accident, and cerebral ischemia, occurred across clinical trials. In 2137 patients with various cancers treated with CYRAMZA, the incidence of all Grade ATE was 1-3%. Grade 3-5 ATE incidence was <1-2%.
- Permanently discontinue CYRAMZA in patients who experience an ATE.

Overall response rate (ORR) was a supportive outcome measure of the RELAY trial. The following ORR results for epidermal growth factor receptor gene mutant (EGFR mut+) metastatic non-small cell lung cancer (mNSCLC) patients are presented. With CYRAMZA plus erlotinib in the intent-to-treat (ITT) population (n equals 224), ORR was 76 percent of patients with a 95 percent confidence interval of 71 to 82 percent. With placebo plus erlotinib in the ITT population (n equals 225), ORR was 75 percent with a 95 percent confidence interval of 69 to 80 percent. ORR was a prespecified secondary efficacy endpoint. ORR was not powered or controlled for type 1 error, and treatment differences observed cannot be regarded as statistically significant.

Hypertension
- An increased incidence of severe hypertension occurred in patients receiving CYRAMZA. Across five clinical studies, excluding RELAY, in 1916 patients with various cancers treated with CYRAMZA, the incidence of all Grade hypertension ranged from 11-26%. Grade 3-5 hypertension incidence ranged from 6-15%. In 221 patients with NSCLC receiving CYRAMZA in combination with erlotinib in the RELAY study, the incidence of new or worsening hypertension was higher (45%), as was the incidence of Grade 3-5 hypertension (24%). Of the patients experiencing new or worsening hypertension in RELAY (N=100 CYRAMZA and erlotinib; N=27 placebo and erlotinib), 13% of those treated with CYRAMZA and erlotinib required initiation of 3 or more antihypertensive medications compared to 4% of patients treated with placebo and erlotinib.
-
Control hypertension prior to initiating treatment with CYRAMZA. Monitor blood pressure every two weeks or more frequently as indicated during treatment. Withhold CYRAMZA for severe hypertension until medically controlled. Permanently discontinue CYRAMZA for medically significant hypertension that cannot be controlled with antihypertensive therapy or in patients with hypertensive crisis or hypertensive encephalopathy.

- IRR, including severe and life-threatening IRR, occurred in CYRAMZA clinical trials. Symptoms of IRR included rigors/tremors, back pain/spasms, chest pain and/or tightness, chills, flushing, dyspnea, wheezing, hypoxia, and paresthesia.
