NCCN Category 1 (preferred) after osimertinib3

Amivantamab-vmjw (RYBREVANT®) + chemotherapy* is the ONLY NCCN Category 1 (preferred) treatment option for patients with EGFR+† nonsquamous mNSCLC progressing on osimertinib who are symptomatic with multiple systemic lesions.

*Chemotherapy is carboplatin and pemetrexed.
†EGFR exon 19 deletion or exon 21 L858R mutations.

Interim OS results1

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.

*Defined as time from randomization until the date of objective intracranial disease progression or death, whichever comes first, based on BICR using RECIST v1.1. Specifically, intracranial disease progression is defined as having progression of brain metastasis or occurrence of new brain lesion.5

At 12 months, 50% of patients remained intracranial progression-free on RYBREVANT® + chemotherapy and 34% on chemotherapy alone2

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

MARIPOSA-2 is a randomized, open-label, multicenter, Phase 3 trial. Eligible patients were required to have locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations and progressive disease on or after receiving osimertinib. Patients with asymptomatic or previously treated and stable intracranial metastases were eligible to enroll. Patients were randomized (1:2:2) to receive RYBREVANT® in combination with carboplatin and pemetrexed (n=131), carboplatin and pemetrexed (n=263), or RYBREVANT® as part of another combination regimen. The evaluation of efficacy for metastatic NSCLC relied upon comparison between RYBREVANT® in combination with chemotherapy and chemotherapy alone.

Safety

Safety profile of RYBREVANT® + chemotherapy in the MARIPOSA-2 trial1

Majority of ARs were Grades 1 and 2

ARs (≥10%) in patients in MARIPOSA-2

Adverse Reaction TableAdverse Reaction Table Mobile
  • Serious ARs occurred in 32% of patients who received RYBREVANT® + chemotherapy and 20% of patients who received chemotherapy alone1,2
  • Serious ARs in >2% of patients included dyspnea (3.1%), thrombocytopenia (3.1%), sepsis (2.3%), and pulmonary embolism (2.3%)1
  • Fatal ARs occurred in 2.3% of patients who received RYBREVANT® + chemotherapy and 1% of patients who received chemotherapy alone1,2
  • The most common ARs (occurring in ≥20% of patients) were rash, IRRs, fatigue, nail toxicity, nausea, constipation, edema, stomatitis, decreased appetite, musculoskeletal pain, vomiting, and COVID-191
  • Clinically relevant ARs in <10% of patients who received RYBREVANT® + chemotherapy include abdominal pain, hemorrhoids, dizziness, visual impairment, trichomegaly, keratitis, and ILD1

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

Lab AbnormalitiesLab Abnormalities Mobile

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 study, most IRRs occurred during the first infusion (Week 1, Day 1) and rarely during subsequent infusions4

IRRIRR Mobile
  • 91% of IRRs were Grades 1 to 24
  • Median time to onset of first IRR was 1 hour (range, 0.02 to 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 severity1
  • If an anaphylactic reaction occurs, permanently discontinue RYBREVANT®1
  • Signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting1

AR, adverse reaction; ILD, interstitial lung disease; IRR, infusion-related reaction.

Discontinuation Rates and Dose Modifications

~90% of patients treated with RYBREVANT® + chemotherapy were able to stay on treatment without AR-related discontinuation1

11% of patients permanently discontinued RYBREVANT® due to ARs1

  • Most frequent ARs leading to treatment discontinuation in ≥5% of patients were IRRs

Dose interruptions of RYBREVANT® due to an AR occurred in 60% of patients1

  • IRRs requiring infusion interruptions occurred in 52% of patients
  • ARs requiring dose interruption in ≥5% of patients included IRR, rash, and fatigue

Dose reductions of RYBREVANT® due to an AR occurred in 17% of patients1

  • ARs requiring dose reductions in ≥2% of patients included rash
