Study of Osimertinib in Patients With a Lung Cancer With Brain or Leptomeningeal Metastases With EGFR Mutation (ORBITAL)

A Phase II, Multi-centre Study, to Evaluate the Efficacy and Safety of Osimertinib Treatment for Patients With EGFR-mutated Non-small Cell Lung Cancer (NSCLC) With Brain or Leptomeningeal Metastases

Treatment of non-small cell lung cancer (NSCLC) with Epidermal Growth Factor Receptor (EGFR) mutation is mainly based on tyrosine kinase inhibitors (TKIs) targeting EGFR. 1st or 2nd generation inhibitors have been shown to be superior to chemotherapy in terms of Progression-Free Survival (PFS) when used as 1st line treatment.

In case of progression at several metastatic sites, systemic treatment will be considered and will depend on the presence of the TKI resistance mutation, the T790M mutation. In the presence of the T790M mutation, osimertinib is superior to chemotherapy in terms of progression-free survival, while in the absence of the T790M mutation, platinum salt chemotherapy is recommended. In case of local progression, treatment of the site in progression by radiotherapy and/or surgery is considered. As these local treatments can cause long-term adverse effects, systemic treatments are increasingly being considered in this indication.

Brain and leptomeningeal metastases are the most frequent isolated site of progression in EGFR mutated patients treated with TKI. The high frequency of isolated cerebral and leptomeningeal progression is a consequence of the lower diffusion of 1st and 2nd generation TKIs in the central nervous system (CNS). Osimertinib is a 3rd generation TKI that has the particularity of overcoming the T790M mutation and having greater brain penetration than 1st or 2nd generation TKIs, which could make it an attractive therapeutic option in the event of brain progression or leptomeningeal progression. However, its efficacy in patients with cerebral or leptomeningeal metastases is still poorly understood.

Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses, which in the investigator's opinion makes it undesirable for the patient to participate in the trial or which would jeopardise compliance with the protocol, or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV).Active infection will include any patients receiving treatment for infection. Participants with a resolved or chronic infection HBV are eligible if they are:

  18. Currently receiving (or unable to stop use at least 3 week prior to receiving the first dose of study treatment) medications or herbal supplements known to be strong inducers of CYP3A4 (see Appendix 2). All patients must try to avoid concomitant use of any medications, herbal supplements and/or ingestion of foods with known inducer effects on CYP3A4.
