Information is also accessible through the patient and families tab. Family friendly summaries are created and reviewed by our advocacy partners. The information is updated to the best of our knowledge but might not reflect the latest information. Note that most studies are only available at a limited number of sites, please click on ‘further information’ for details. Studies, particularly early phase trials, may also temporarily close to enrolment or not have slots available for all treatment groups. In all cases, study teams at individual C17 centres will have the most up-to-date information.

Study Description

Some neuroblastoma have a specific genetic change or mutation called an ALK aberration.  ALK, or anaplastic lymphoma kinase, has been found in several adult and pediatric cancers.  ALK aberrations are present in about 14% of newly diagnosed patients with high-risk neuroblastoma, and can be found more frequently at the time of relapse.  Lorlatinib is a drug called an ALK inhibitor. It is expected to slow or stop the growth of cancer cells which have the ALK aberration. The aim of this phase I/II study is to evaluate the dose, safety, and tolerability of lorlatinib, including the effect it has on the cancer.  Lorlatinib will be given alone or in combination with chemotherapy in children with refractory, relapsed or progressive neuroblastoma with ALK alterations.

Inclusion Criteria
  • Patients must have a diagnosis of neuroblastoma either by histologic verification (looking at a sample of the tumour under a microscope) of neuroblastoma and/or demonstration of tumor cells in the bone marrow with increased urinary catecholamines (HVA/VMA).
  • Patients are required to have an activating ALK aberration in their tumor, which is identified through genetic testing.
  • Patients must have high risk neuroblastoma. Patients who were initially considered low or intermediate risk, but then reclassified as high risk are also eligible.
  • Patients must have at least ONE of the following: 1) Recurrent/progressive disease at any time prior to study enrollment, 2) Refractory disease, 3) Persistent disease


Multiple other inclusion and exclusion criteria could apply and will be reviewed by your treating team.
