Bring the potential of ROZLYTREK® to life


A potent ROS1 and TRK inhibitor1


ROZLYTREK: A potent ROS1 and TRK inhibitor1

  • ROZYLTREK is a selective tyrosine kinase inhibitor used to treat ROS1+ NSCLC and NTRK fusion+ solid tumours1
  • ROZLYTREK demonstrates antitumour activity within the CNS1
  • It has shown efficacy in ROS1+ NSCLC and NTRK fusion+ solid tumours clinical trials1

Introduction to ROZLYTREK

A selective tyrosine kinase inhibitor that targets
TRK and ROS1 fusion proteins

ROZLYTREK indications1

ROZLYTREK as monotherapy is indicated for the treatment of adult and paediatric patients 12 years of age and older, with solid tumours, expressing a NTRK gene fusion, 

  • who have a disease that is locally advanced, metastatic or where surgical resection is likely to result in severe morbidity, and
  • who have not received a prior NTRK inhibitor,
  • who have no satisfactory treatment options.

ROZLYTREK as monotherapy is indicated for the treatment of adult patients with ROS1-positive, advanced NSCLC not previously treated with ROS1 inhibitors.

Mode of action and CNS activity

ROZLYTREK blocks all subtypes of TRK (TRKA, TRKB and TRKC) and ROS1 tyrosine kinases1,2

ROZLYTREK inhibits TRK and ROS1 kinases, preventing the hyperactivation of downstream signalling pathways that lead to unconstrained cell proliferation1


A potent, selective TRK and ROS1 inhibitor, demonstrating antitumour activity within the CNS1

  • Systemic drugs must cross the blood-brain barrier, and remain in the CNS to be effective there3–6
  • ROZLYTREK is a weak substrate of P-glycoprotein and therefore is able to achieve clinically meaningful concentrations in the CNS1,7

CNS metastases are associated with significant morbidity and poor survival8

  • The most common primary tumour sites for CNS metastases are:9
    • Lung
    • Breast (the most common cause of brain metastases in women)
    • Skin
    • Kidney
    • Gastrointestinal tract
  • In ROS1+ advanced NSCLC, up to 40% of patients have CNS metastases at diagnosis10
    • A retrospective analysis found that approximately half of lung cancer patients with CNS metastases were asymptomatic for CNS disease11
    • For 47% of patients with ROS1+ advanced NSCLC receiving crizotinib, the CNS is the first and only site of progression10
  • NTRK fusion-positive cancers are histologic types with significant rates of brain metastasis, commonly seen in NSCLC and melanoma12
    • NTRK fusions are now considered an important molecular marker in patients with CNS metastases13
    • The activity of TRK inhibitors in the CNS can enable significant improvement of patients’ outcome by specific targeting13
