Interim overall survival results1

MARIPOSA-2 clinical trial interim overall survival results: HR=0.73

At the prespecified second interim analysis of OS, with 85% of the deaths needed for the final analysis, there was no statistically significant difference in OS. The median OS was 17.7 months (95% CI: 16, 22.4) in the RYBREVANT® + chemotherapy arm and 15.3 months (95% CI: 13.7, 16.8) in the chemotherapy arm, with an HR of 0.73 (95% CI: 0.54, 0.99). Final OS analysis has not yet been formally tested.

Intracranial PFS2*

Study Design

For previously treated adult patients with locally advanced or metastatic EGFR+ NSCLC

MARIPOSA-2: The first approved EGFR-targeting therapy in combination with chemotherapy post-osimertinib1,2

MARIPOSA-2 is an open-label, multicenter, phase 3 trial. Patients with asymptomatic or previously treated and stable intracranial metastases were eligible to enroll. The evaluation of efficacy relied upon comparison between RYBREVANT® in combination with chemotherapy and chemotherapy alone.

Select laboratory abnormalities that worsened from baseline (≥20%) in MARIPOSA-21

Lab abnormalities in the MARIPOSA-2 clinical trialLab abnormalities in the MARIPOSA-2 clinical trial

Based on the pooled safety population (N=281), the most common grade 3 to 4 laboratory abnormalities (≥2%) were decreased neutrophils, decreased leukocytes, decreased platelets, decreased hemoglobin, decreased potassium, decreased sodium, increased alanine aminotransferase, increased gamma-glutamyl transferase, and decreased albumin.1

In the MARIPOSA-2 trial, most IRRs occurred during the first infusion (week 1, day 1) and rarely during subsequent infusions4

IRR rates in the MARIPOSA-2 clinical trialIRR rates in the MARIPOSA-2 clinical trial
  • 91% of IRRs were grades 1 to 24
  • Median time to onset of first IRR was 1 hour (range, 0.02–13.5 hours)4
  • Monitor patients for any signs and symptoms of IRRs during RYBREVANT® infusion in a setting where cardiopulmonary resuscitation medication and equipment are available. Interrupt infusion if IRR is suspected. Reduce the infusion rate or permanently discontinue RYBREVANT® based on severity7
  • If an anaphylactic reaction occurs, permanently discontinue RYBREVANT®7
  • Signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting7

Prophylaxis may reduce the risk of IRRs and dermatologic ARs

Dose Modifications and Discontinuation Rates

Adaptable dosing is available to help your patients manage ARs and stay on treatment4*

Most patients used dose modification to continue treatment with RYBREVANT®.1
  • Permanent discontinuation of RYBREVANT® due to an AR occurred in 11% of patients
  • Dose interruption due to an AR occurred in 60% of patients
  • Dose reductions due to an AR occurred in 17% of patients

*Certain types and severity of ARs require discontinuation after first occurrence.1
