Nerlynx + capecitabine protects against progression1,2
PFS in patients with HER2+ mBC vs lapatinib + CAPECITABINE1,2
29% PFS rate at 12 months vs 15% with lapatinib + capecitabine1

Nerlynx safety in NALA1
Most common adverse reactions ( ≥5%)
The USPI warnings and precautions do not include cardiac, pulmonary, or hematologic toxicities, or increased risk for secondary malignancy.1

Drug Interactions1
- Gastric acid–reducing agents: Avoid concomitant use with proton pump inhibitors. Separate Nerlynx by at least 2 hours before or 10 hours after H2-receptor antagonists. Or separate Nerlynx by at least 3 hours after antacids
- Strong CYP3A4 inhibitors: Avoid concomitant use
- P-gp and moderate CYP3A4 dual inhibitors: Avoid concomitant use
- Strong or moderate CYP3A4 inducers: Avoid concomitant use
- Certain P-gp substrates: Monitor for adverse reactions of P-gp substrates for which minimal concentration change may lead to serious adverse reactions when used concomitantly with Nerlynx
- No grade 4 diarrhea.1
- Renal impairment includes acute kidney injury, blood creatinine increased, renal failure, and renal impairment.1
Dose escalation in HER2+ mBC
Dose escalation in HER2+ mBC
Start Nerlynx at a lower dose and titrate up to the full recommended dose to help manage diarrhea1
Nerlynx + capecitabine is administered in a 21-day dosing cycle1
Cycle 1—Nerlynx dose escalation1
Cycle 2 and beyond—full recommended Nerlynx dose1
- Nerlynx is an oral once-daily therapy taken continuously until disease progression or unacceptable toxicities1
- Capecitabine is taken with water within 30 minutes after a meal on days 1 to 14 of each 21-day cycle3,*
- If diarrhea occurs, treat with antidiarrheal medications, fluids, and electrolytes as clinically indicated1
- Refer to the capecitabine Prescribing Information when NERLYNX is used in combination with capecitabine.
- mBC: metastatic breast cancer.

Once-daily oral dosing with Nerlynx
IMPORTANT DOSING INFORMATION1
- The recommended dose is 240 mg once daily*
- Instruct patients to take Nerlynx with food at approximately the same time every day
- Nerlynx tablets should be swallowed whole (not be chewed, crushed, or split prior to swallowing)
- Patients with metastatic HER2+ breast cancer should take Nerlynx until disease progression or unacceptable toxicities
- If a patient misses a dose, do not replace a missed dose, and instruct the patient to resume Nerlynx with the next scheduled daily dose
- Dose interruptions and/or dose reductions are recommended based on individual safety and tolerability
- Hepatic impairment: reduce the starting dose to 80 mg in patients with severe hepatic impairment
- Discontinue Nerlynx for patients with adverse reactions that fail to recover to grade 0-1 or baseline, with toxicities that result in a treatment delay >3 weeks, or if unable to tolerate 120 mg daily
- If diarrhea occurs, treat with antidiarrheal medications, fluids, and electrolytes as clinically indicated.1
Dose adjustments to help manage side effects1
Dose modifications: management of diarrhea1
Management of diarrhea may require antidiarrheals, dietary changes, supportive care, and appropriate dose modifications
Severity of diarrhea*
Hypothetical patient case
- Based on CTCAE.
- Institute the following: diet modifications, maintain ~2 L fluid intake per day.1
- Refer to the capecitabine Prescribing Information when NERLYNX is used in combination with capecitabine.1
- Reduce capecitabine if Nerlynx was previously reduced or reduce Nerlynx if capecitabine was previously reduced.1
- Once diarrhea resolves to grade ≤1 or baseline, start loperamide 4 mg with each subsequent Nerlynx administration (not to exceed 16 mg/day).1
