RYBREVANT® is a targeted antibody, which is a different kind of treatment from immunotherapy, chemotherapy, and TKIs

Clinical Benefits of RYBREVANT®

In a clinical trial, RYBREVANT® was studied in 81 people who had mNSCLC with EGFR exon 20 insertion mutations whose disease had worsened while on or after chemotherapy that contains platinum

  • Most people in the trial were women (59%)
  • Over half never smoked (53%)
  • The main goal of the trial was to measure the number of people who responded to RYBREVANT® overall

*The disappearance of all signs of cancer in response to treatment does not always mean the cancer has been cured.

What you should know about infusion-related reactions (IRRs)

Your care team is trained to help you with any IRRs you may experience, so make sure to tell them how you’re feeling during your infusion. Here are some things you should know about IRRs:

IRRs are common with RYBREVANT® and can be severe or serious

IRRs can involve shortness of breath, fever, chills, nausea, flushing, chest discomfort, lightheadedness, or vomiting that occur during your infusion

IRRs were one of the most common side effects in a clinical study, and occurred in 66% of people treated with RYBREVANT®

65% of IRRs occur on Day 1 of the first dose, and typically happen within the first hour of an infusion. On Day 2 of the first dose, 3.4% of people experienced an IRR. During Week 2, only 0.4% of people experienced an IRR. During all other infusions, 1.1% of people experienced an IRR

Your healthcare provider will give you medicines before each dose of RYBREVANT® to help reduce the risk of these reactions

Pay close attention to how you feel during an infusion, and make sure to let your care team know if you experience any discomfort—they know how to help.
