A Phase 2/3 interventional study of Alectinib and Atezolizumab in Haematological Malignancy and Solid Tumour, sponsored by Cancer Research UK. Recruiting at 27 sites in United Kingdom. Per ClinicalTrials.gov, last updated 2026-07-01.
Sponsored by Cancer Research UK · Phase 2/3, Interventional, and Treatment
DETERMINE is an open-label phase II/III trial. It will look at targeted treatments in rare cancers or common cancers with rare genetic change (mutation). Patients must have a cancer with an identified mutation. This could be found during routine testing or as part of another research programme. The DETERMINE trial will recruit adults, teenagers and children. If a drug is found to benefit a new patient group, the study team will work with the NHS and the Cancer Drugs Funds to see if these drugs can be available for patients in the future. This clinicaltrials.gov record refers to the Overall Trial Protocol (Master Screening Record), additional records will be added to clinicaltrials.gov for each treatment arm.
DETERMINE is an umbrella-basket platform trial to evaluate the efficacy of licensed targeted therapies in rare* adult, paediatric and teenage/young adult (TYA) cancers with actionable genomic alterations, including common cancers with rare actionable alterations.
*Rare is defined generally as incidence less than 6 cases in 100,000 patients (includes paediatric and TYA cancers) or common cancers with rare alterations.
The number of treatment arms opened will depend on the number of licensed medicines identified for inclusion. Each trial cohort 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.
This clinicaltrials.gov record refers to the Overall Trial Protocol (Master Screening Record), please refer to the references section for links to the individual treatment arm records.
The main aims of the clinical trial arms are:
This Master Screening Record will capture the number of patients with a cancer containing the appropriate genetic alteration that have been successfully allocated and consented to each arm. The trial results (according to the protocol defined outcome measures) will be reported per-arm for each treatment arm.
The ultimate aim is to translate positive clinical findings to the NHS to provide new treatment options for rare adult, paediatric and TYA cancers.

THE PATIENT MUST FULFIL THE ELIGIBILITY CRITERIA OUTLINED BELOW AND WITHIN THE SPECIFIC TREATMENT ARM APPENDIX TO WHICH THEY ARE ENROLLED.
Core Inclusion Criteria:
Any patient (adult patients or children and TYA as defined in each treatment arm appendix) with proven locally advanced or cancer (solid tumour or haematological ) who has:
Women of are eligible provided that they meet the following criteria:
Core exclusion criteria:
Is (or plans to be) a patient in another interventional clinical trial, whilst taking part in this trial. Participation in an observational trial which does not involve administration of an Medicinal Product (IMP) and which, in the opinion of the local Investigator, would not place an unacceptable burden on the patient would be acceptable e.g. sample collection* or QoL studies.
*for paediatric patients participating in other studies involving tissue/circulating tumour (ct) DNA/other blood collection, consideration would need to be given to the total blood volumes collected (as per the European Medicines Agency blood volume limits for children).
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Number of patients who consent to each arm.
This is a master screening entry with sub-study entries to capture the results of each arm. As such a primary outcome measure for this entry is not relevant, however this entry will be used to report the number of patients with a cancer containing the appropriate genetic alteration that have been successfully allocated and consented to each arm.
Time frame: Up to 5 years.
Plan to share: Yes — Individual de-identified patient data will be shared with researchers whose proposed use of the data is approved by a review committee of the Sponsor.
Supporting information: Study protocol, Statistical analysis plan, Informed consent form
Time frame: All requests made within 5 years from last patient last visit for each of the treatment arms will be considered (refer to individual treatment arm records); requests made subsequently will be considered where possible.
Access criteria: When a request has been approved, Cancer Research UK will provide access to the de-identified individual patient-level data and appropriate supporting information. A signed Data Sharing Agreement must be in place before accessing requested information. Requests should be submitted to drugdev@cancer.org.uk
