Anaplastic Large Cell Lymphoma

This clinical trial is looking at a drug called alectinib. Alectinib is approved as standard of care treatment for adult patients with certain types of lung cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Alectinib works in lung cancer patients with a particular mutation in their cancer known as ALK. Investigators now wish to find out if it will be useful in treating patients with other cancer types which have the same mutation. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
