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

Cancer Clinical Trial

Official title: DETERMINE (Determining Extended Therapeutic Indications for Existing Drugs in Rare Molecularly Defined Indications Using a National Evaluation Platform Trial): An Umbrella-Basket Platform Trial to Evaluate the Efficacy of Targeted Therapies in Rare Adult, Paediatric and Teenage/Young Adult (TYA) Cancers With Actionable Genomic Alterations, Including Common Cancers With Rare Actionable Alterations. Treatment Arm 03: Entrectinib in Adult, Teenage/Young Adults and Paediatric Patients With ROS1 Gene Fusion-positive Cancers.

Status Recruiting

Clinical Trial 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 of age or older 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.

Clinical Trial 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 where promising activity is identified 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 participant based on molecularly-defined cohorts.

Screening: Consenting participants undergo biopsy and collection of blood samples for research purposes.

Treatment: Participants will receive entrectinib until disease progression, unacceptable toxicity or withdrawal of consent. Participants will also undergo collection of blood samples at various intervals while receiving treatment and at the end of trial visit (EoT).

After completion of study treatment, patients are followed up every 3 months for 2 years
