IMPORTANT SAFETY INFORMATION
NERLYNX® (neratinib) tablets, for oral use
INDICATIONS AND USAGE: NERLYNX is a kinase inhibitor
As a single agent, for the extended adjuvant treatment of adult patients with early-stage HER2-positive breast cancer,
to follow adjuvant trastuzumab-based therapy.
In combination with capecitabine, for the treatment of adult patients with advanced or metastatic HER2-positive breast
cancer who have received two or more prior anti-HER2 based regimens in the metastatic setting.
WARNINGS AND PRECAUTIONS:
Diarrhea: Aggressively manage diarrhea. If diarrhea occurs despite recommended prophylaxis, treat with additional
anti-diarrheals, fluids, and electrolytes as clinically indicated. Withhold NERLYNX in patients experiencing severe
and/or persistent diarrhea. Permanently discontinue NERLYNX in patients experiencing Grade 4 diarrhea or Grade ≥2 diarrhea that occurs after maximal dose reduction.
Hepatotoxicity: Monitor liver function tests monthly for the first 3 months of treatment, then every 3 months while on treatment and as
clinically indicated. Withhold NERLYNX in patients experiencing Grade 3 liver abnormalities and permanently discontinue
NERLYNX in patients experiencing Grade 4 liver abnormalities.
Embryo-Fetal Toxicity: NERLYNX can cause fetal harm. Advise patients of potential risk to a fetus and to use effective contraception.
ADVERSE REACTIONS: The most common adverse reactions (reported in ≥5% of patients) were:
NERLYNX as a single agent: diarrhea, nausea, abdominal pain, fatigue, vomiting, rash, stomatitis, decreased appetite,
muscle spasms, dyspepsia, AST or ALT increased, nail disorder, dry skin, abdominal distention, epistaxis, weight
decreased, and urinary tract infection.
NERLYNX in combination with capecitabine: diarrhea, nausea, vomiting, decreased appetite, constipation,
fatigue/asthenia, weight decreased, dizziness, back pain, arthralgia, urinary tract infection, upper respiratory tract
infection, abdominal distention, renal impairment, and muscle spasms.
To report SUSPECTED ADVERSE REACTIONS, contact Puma Biotechnology, Inc. at
1-844-NERLYNX (1-844-637-5969) or FDA at 1-800-FDA-1088 or
Gastric acid reducing agents: Avoid concomitant use with proton pump inhibitors. When patients require gastric acid
reducing agents, use an H2-receptor antagonist or antacid. Separate NERLYNX by at least 3 hours with antacids. Separate
NERLYNX by at least 2 hours before or 10 hours after H2-receptor antagonists.
Strong CYP3A4 inhibitors: Avoid concomitant use.
Moderate CYP3A4 and P-glycoprotein (P-gp) dual inhibitors: Avoid concomitant use.
Strong or moderate CYP3A4 inducers: Avoid concomitant use.
P-glycoprotein (P-gp) substrates: Monitor for adverse reactions of narrow therapeutic agents that are P-gp substrates
when used concomitantly with NERLYNX.
USE IN SPECIFIC POPULATIONS:
Lactation: Advise women not to breastfeed.
