Convenient once-daily, oral dosing with NERLYNX3

The recommended daily dose of NERLYNX is six 40-mg tablets (240 mg total), taken continuously for 1 year3

Instruct patients to take NERLYNX with food at approximately the same time every day

NERLYNX tablets should be swallowed whole (tablets should not be chewed, crushed, or split prior to swallowing)

If a patient misses a dose, do not replace missed dose, and instruct the patient to resume NERLYNX with the next scheduled daily dose

Avoid grapefruit in any form

Reaching full dose is important to achieve the efficacy demonstrated in ExteNET22

  • No patients in the NERLYNX dose escalation arm discontinued due to diarrhea after the first month*
  • CONTROL is a phase 2, open-label, nonrandomized, multicenter, multinational study to evaluate the effects of dose escalation or antidiarrheal prophylaxis on diarrhea associated with NERLYNX




*Treatment is ongoing in 20 patients (33%) in the dose escalation cohort.

PRN: as needed.

Supportive Care

  • Used at the dispensing pharmacy, with prescription(s) at local retail pharmacy, or through Puma Specialty Pharmacy network

Proactive management, including antidiarrheal medications, and dietary changes may help patients remain on therapy3,22

NERLYNX dose modifications options3

  • Patients who experienced dose holds and reductions maintained efficacy in the extended adjuvant setting23

  • NERLYNX dose modifications are recommended based on individual safety and tolerability; adjust the dose as clinically indicated3

  • Some adverse reactions may require dose interruption, reduction, or discontinuation3,*

*Discontinue NERLYNX for patients who fail to recover to Grade 0-1 from treatment-related toxicity, for toxicities that result in a treatment delay >3 weeks, or for patients that are unable to tolerate 120 mg daily.

Management of diarrhea requires antidiarrheals, dietary changes, supportive care, and appropriate dose modifications3

Severity of diarrhea*

NCI CTCAE grading for diarrhea24

Perform stool cultures as clinically indicated to exclude infectious causes of Grade 3 or 4 diarrhea of any grade with complicated features3,‡

Grade 1
Increase of <4 stools per day over baseline; mild increase in ostomy output compared to baseline
Grade 2
Increase of 4–6 stools per day over baseline; moderate increase in ostomy output compared to baseline; limiting instrumental ADL
Grade 3
Increase of ≥7 stools per day over baseline; hospitalization indicated; severe increase in ostomy output compared to baseline; limiting self-care ADL
Grade 4
Life-threatening consequences; urgent intervention indicated

Based on NCI CTCAE v5.0 grading.

ADL: activites of daily living; NCI CTCAE: National Cancer Institute Common Terminology Criteria for Adverse Events v5.0.

*Grading per CTCAE v5.0. Dose modification guidance per NERLYNX package insert.

Institute the following: diet modifications, maintain ~2 L fluid intake per day, and once event resolves to grade ≤1 or baseline, start loperamide 4 mg with each subsequent NERLYNX administration.

Complicated features include dehydration, fever, hypotension, renal failure, or grade 3 or 4 neutropenia.

§Despite being treated with optimal medical therapy.

Management of other adverse events associated with NERLYNX may require a dose interruption or treatment discontinuation.

General Toxicities*
recommended action
Hold NERLYNX until recovery to Grade ≤1 or baseline within 3 weeks of stopping treatment, then resume NERLYNX at the next lower dose level
Discontinue NERLYNX permanently
Hepatic Impairment
  • Reduce NERLYNX starting dose to 80 mg in patients with severe hepatic impairment (Child Pugh C)
  • No dose modifications are recommended for patients with mild to moderate hepatic impairment (Child Pugh A or B)
  • Evaluate liver function tests in patients who experience Grade ≥3 diarrhea requiring IV fluid treatment or any signs or symptoms of hepatotoxicity
  • Collect fractionated bilirubin and prothrombin time during hepatotoxicity evaluation
recommended action
Grade 3 ALT or AST
Grade 3 bilirubin
  • Hold NERLYNX until recovery to Grade ≤1
  • Evaluate alternative causes
  • Resume NERLYNX at the next lower dose level if recovery to Grade ≤1 occurs within 3 weeks. If Grade 3 ALT or AST, or bilirubin occurs again despite one dose reduction, permanently discontinue NERLYNX
Grade 4 ALT or AST
Grade 4 bilirubin
  • Discontinue NERLYNX permanently
  • Evaluate alternative causes

*Also refer to the diarrhea and hepatotoxicity dose modifications on this page.

Grading per CTCAE v5.0. Dosing modification guidance per NERLYNX package insert.

ALT: alanine aminotransferase; AST: aspartate aminotrasferase; IV: intravenous; ULN: upper limit of normal.

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.
