In this Article, the description for the Supplementary Information file stated: “This file contains Pre-clinical rationale for triaging participants to genotype-matched targeted therapies in the NLMT.”. However, the initial Supplementary Information file uploaded contained only the trial protocol and did not contain the rationale. The Supplementary Information file has now been replaced online, and the description has been updated to read: “This file contains pre-clinical rationale for triaging participants to genotype-matched targeted therapies in the NLMT and Protocol version 8.0, in use on 30 November 2019.”.

In addition, the first four sentences of the Acknowledgements section have been altered to read: ‘The Investigators and Sponsor thank all the patients and their families who participated in this trial, as well as the NHS Trusts and staff and the members of the Trial Steering Committee, chaired by R.
