Dosage

Treatment with Vitrakvi should be initiated by physicians experienced in the administration of anticancer therapies.

The presence of a neurotrophic tyrosine receptor kinase (NTRK) gene fusion in a tumour specimen should be confirmed by a validated test prior to initiation of treatment with Vitrakvi.

The recommended dose of Vitrakvi in adults is 100 mg taken orally, twice daily until the patient is no longer clinically benefiting from therapy or until unacceptable toxicity occurs.

Dosing in paediatric patients is based on body surface area (BSA). The recommended dose of Vitrakvi in paediatric patients (1 month to 18 years) is 100 mg/m2 taken orally, twice daily with a maximum of 100 mg per dose until the patient is no longer clinically benefiting from therapy or until unacceptable toxicity occurs.

For further information refer to the Product Information.

Pregnancy category

C

Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

The use of any medicine during pregnancy requires careful consideration of both risks and benefits by the treating health professional. This must not be used as the sole basis of decision making in the use of medicines during pregnancy. The TGA does not provide advice on the use of medicines in pregnancy for specific cases. More information is available from obstetric drug information services in your State or Territory.

What was approved?

Vitrakvi (larotrectinib (as sulfate)) was approved for the following therapeutic use:

Vitrakvi (larotrectinib) has provisional approval in Australia for the treatment of adult and paediatric patients with locally advanced or metastatic solid tumours that:

  • have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion without a known acquired resistance mutation,
  • are metastatic or where surgical resection is likely to result in severe morbidity, and
  • have either progressed following treatment or who have no satisfactory alternative therapy.

The decision to approve this indication has been made on the basis of objective response rate (ORR) and duration of response from single arm clinical studies. The sponsor is required to submit further clinical data to confirm the clinical benefit of the medicine.

What steps were involved in the decision process?

What post-market commitments will the sponsor undertake?

  • Vitrakvi (larotrectinib) is to be included in the Black Triangle Scheme. The PI and CMI for Vitrakvi must include the black triangle symbol and mandatory accompanying text for five years, which starts from the date that the sponsor notifies the TGA of supply of the product, or for the period of provisional registration, whichever is longer.
  • The larotrectinib European Union (EU)-Risk Management Plan (RMP) (version 1.0, dated 30 September 2019, data lock point 12 August 2019), with Australian Specific Annex (version 1.1, dated 26 March 2020), included with submission PM-2019-03170-1-4, and any subsequent revisions, as agreed with the TGA will be implemented in Australia.

    An obligatory component of risk management plans is routine pharmacovigilance. Routine pharmacovigilance includes the submission of periodic safety update reports (PSURs).Reports are to be provided in line with the current published list of EU reference dates and frequency of submission of PSURs until the period covered by such reports is not less than three years from the date of the approval letter, or for the period of provisional registration, whichever is longer.

    The reports are to at least meet the requirements for PSURs as described in the European Medicines Agency's Guideline on good pharmacovigilance practices (GVP) Module VII-periodic safety update report (Rev 1), Part VII.B Structures and processes. Note that submission of a PSUR does not constitute an application to vary the registration.

  • Confirmatory trial data (as identified in the sponsor's plan to submit comprehensive clinical data on the safety and efficacy of the medicine before the end of the 6 years that would start on the day that registration would commence) must be provided.
  • Specifically, the sponsor must conduct studies as described in the clinical study plan in version 1.1 (dated 26 March 2020) of the Australia-Specific Annex. The following study reports should be submitted to TGA:
    • Study 20289 (also known as LOXO-TRK-15002 and NAVIGATE), 'A Phase 2 Basket Study of the Oral TRK Inhibitor larotrectinib in Subjects with NTRK Fusion-Positive Tumors', final study report due second quarter 2024
    • Study 20290 (also known as LOXO-TRK-15003 and SCOUT), 'A Phase 1/2 Study of the Oral TRK Inhibitor LOXO-101 in Pediatric Patients with Advanced Solid or Primary Central Nervous System Tumors', final study report due first quarter 2027
    • Study 20288 (also known as LOXO-TRK-14001), 'A Phase 1 Study of the Oral TRK Inhibitor Larotrectinib in Adult Patients with Solid Tumors', final study report due second quarter2022

Further guidance for sponsors is available on the TGA website.
