Guidelines

Given the rapid change in evidence in many areas of hematology/oncology, readers are encouraged to consider any guideline published 5+ years ago to be for historical purposes, only.

JSCO/ESMO/ASCO/JSMO/TOS

All lines of therapy

Entrectinib monotherapy

Regimen variant #1, pediatric dosing

FDA-recommended dose
Study Dates of enrollment Evidence
Desai et al. 2022 (STARTRK-NG) 2016-05 to 2020-09 Phase 1/2 (RT)

Note: these are the FDA-recommended doses based on age and BSA.

Targeted therapy

  • Entrectinib (Rozlytrek) by the following age- and BSA-based criteria:
    • Older than 1 month old up to 6 months old: 250 mg/m2 PO once per day on days 1 to 28
    • Older than 6 months old AND BSA up to 0.50: 300 mg/m2 PO once per day on days 1 to 28
    • Older than 6 months old AND BSA between 0.51 to 0.80: 200 mg PO once per day on days 1 to 28
    • Older than 6 months old AND BSA between 0.81 to 1.10: 300 mg PO once per day on days 1 to 28
    • Older than 6 months old AND BSA between 1.11 to 1.50: 400 mg PO once per day on days 1 to 28
    • Older than 6 months old AND BSA 1.51 or more: 600 mg PO once per day on days 1 to 28

28-day cycles


Regimen variant #3, flat dose

FDA-recommended dose
Study Dates of enrollment Evidence
Drilon et al. 2017 (ALKA-372-001) 2012-2018 Phase 1 (RT)
Drilon et al. 2017 (STARTRK-1) 2012-2018 Phase 1 (RT)
Doebele et al. 2020 (STARTRK-2) 2015-NR Phase 2 (RT)
