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, Paediatric and Teenage/Young Adult Patients With ROS1 Gene Fusion-Positive Cancers.

Trial ID: NCT05770544

Interventional - Phase 2/3 - Recruiting

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.

• II. Oral, injectable or implantable progestogen-only hormonal contraception associated with inhibition of ovulation
• III. Intrauterine device (IUD)
• IV. Intrauterine hormone-releasing system (IUS)
• V. Bilateral tubal occlusion

• Plus a barrier method if using a hormonal method: male or female condom with or without spermicide; cap, diaphragm or sponge with spermicide OR
• Sexual abstinence;
• Effective from the first administration of entrectinib, throughout the trial and for five weeks after the last administration of entrectinib.
• G. Male patients with partners who are women of childbearing potential are eligible provided that they agree to the following, from the first administration of entrectinib, throughout the trial and for three months after the last administration of entrectinib:
• Agree to take measures not to father children by using a barrier method of contraception (condom plus spermicide) or to sexual abstinence.
• Non-vasectomised male patients with partners who are women of childbearing potential must also be willing to ensure that their partner uses a highly effective method of contraception as in F above.
• Male patients with pregnant or lactating partners must be advised to use barrier method contraception (e.g. condom) to prevent drug exposure of the foetus or neonate.
• All male patients must refrain from donating sperm for the same period.

Exclusion criteria

• or precautions below differ from those specified in the Master Protocol, the entrectinib-specific criteria will take precedence.
