A Phase 2/3 interventional study of Alectinib in Haematological Malignancy, Malignant Neoplasm and Lymphoproliferative Disorders, sponsored by Cancer Research UK. Recruiting at 27 sites in United Kingdom. Per ClinicalTrials.gov, last updated 2025-11-24.
Sponsored by Cancer Research UK · Phase 2/3, Interventional, and Treatment
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.
DETERMINE Treatment Arm 01 (alectinib) aims to evaluate the efficacy of alectinib in ALK-positive rare* adult, paediatric and teenage/young adult (TYA) cancers and in common cancers where an ALK mutation or amplification is considered to be infrequent.
*Rare is defined generally as incidence less than 6 cases in 100,000 patients (includes paediatric and teenagers/young adult cancers) or common cancers with rare alterations.
This treatment arm has a target sample size of 30 evaluable patients. Sub-cohorts may be defined and further expanded to a target of 30 evaluable patients each.
The ultimate aim is to translate positive clinical findings to the NHS (Cancer Drugs Fund) to provide new treatment options for rare adult, paediatric and TYA cancers.
OUTLINE:
Pre-screening: The Molecular Tumour Board makes a treatment recommendation for the patient based on molecularly-defined cohorts (See information on Master Screening Protocol below).
Screening: Consenting patients undergo biopsy and collection of blood samples for research purposes.
Treatment: Patients will receive alectinib until disease progression without clinical benefit, unacceptable adverse events (AEs) or withdrawal of consent. Patients will also undergo collection of blood samples at various intervals while receiving treatment and at EoT.
After completion of study treatment, patients are followed up every 3 months for 2 years.

EQ-5D Standardised Area Under Index Value Curve (EQ5DSAUC) in adult patients
For adult populations, two measures of Quality of Life (QoL) will be generated from patient completion of the EQ-5D-5L questionnaire. For each measure, scores based on responses from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean EQ5DSAUC and 95% credible interval.
Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).
Mean change from baseline in the PedsQL 4.0 Standardised Area Under total Scale Score Curve (PedsSAUC) in paediatric patients.
For paediatric populations multiple measures of QoL will be generated from patient completion of the, PedsQL 4.0 (4 measures). The Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean PedsSAUC and 95% credible interval.
Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).

For paediatric populations multiple measures of QoL will be generated from patient's parent completion of the PedsQL 4.0 (4 measures). The Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean PedsSAUC and 95% credible interval.
Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).

For each patient the Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean QLQSAUC and 95% credible interval.
Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).
