DETERMINE Trial Treatment Arm 03: Entrectinib in Adult, Paediatric and Teenage/Young Adult Patients With ROS1 Gene Fusion-positive Cancers.

Sponsor:

Cancer Research UK

Brief Summary:

This clinical trial is looking at a drug called entrectinib. Entrectinib is approved as standard of care treatment for adult patients with non-small cell lung cancer (NSCLC) which have a particular molecular alteration called ROS1-positive, and patients 12 years old or above with solid tumours which have another type of change in the cancer cells. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Investigators now wish to find out if it will be useful in treating patients with other cancer types which have the same molecular alteration (ROS1-positive). 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.

Detailed Description:

DETERMINE Treatment Arm 03 (entrectinib) aims to evaluate the efficacy of entrectinib in ROS1 gene fusion-positive rare\* adult, paediatric and teenage/young adult (TYA) cancers and in common cancers where a ROS1 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. Screening: Consenting patients undergo biopsy and collection of blood samples for research purposes. Treatment: Patients will receive entrectinib until disease progression without clinical benefit, unacceptable toxicity or withdrawal of consent. Patients will also undergo collection of blood samples at various intervals while receiving treatment and at the end of treatment visit (EoT). After completion of study treatment, patients are followed up every 3 months for 2 years THE DETERMINE TRIAL MASTER (SCREENING) PROTOCOL: Please see DETERMINE Trial Master (Screening) Protocol record (NCT05722886) for information on the DETERMINE Trial Master Protocol and applicable documents.

\*When entrectinib-specific inclusion/exclusion criteria or precautions below differ from those specified in the Master Protocol, the entrectinib-specific criteria will take precedence.

estimated glomerular filtration rate (eGFR): ≥30 mL/min (uncorrected value)
Coagulation - prothrombin (PT) (or international normalized ratio \[INR\]), and activated partial thromboplastin clotting time (aPTT): ≤1.5 × limit of normal (unless patient is on anticoagulants e.g. warfarin \[INR should be stable and within indicated therapeutic range\], or direct oral anticoagulants \[DOAC\]).
E. PAEDIATRIC PATIENTS (\<18 years): Adequate organ function as per haematological and biochemical indices within the ranges shown below. These measurements should be performed to confirm the patient's eligibility.
Hb: ≥80 g/L (transfusion allowed)
ANC: ≥1.0 × 10\^9/L (no GCSF support in preceding 72 hours)
Platelet count: ≥75 × 10\^9/L (unsupported for 72 hours)
