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 04: Trastuzumab in Combination With Pertuzumab in Adult, Paediatric and Teenage/Young Adult Patients With Cancers With HER2 Amplification or Activating Mutations.
In Brief
A Phase 3 clinical trial evaluating Trastuzumab and Pertuzumab for Haematological Malignancy and 10 related conditions. Currently recruiting, targeting 30 participants across 27 sites.
Detailed Summary
This clinical trial is looking at a combination of drugs called trastuzumab and pertuzumab. This combination of drugs is approved together as standard of care treatment for adult patients with breast cancer (often with other anti-cancer drugs). This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Trastuzumab and pertuzumab work in patients with these types of cancers which have a molecular alteration called HER2 amplification or HER2 activating mutation. Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also HER2 amplified or HER2 mutated. 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.

Interventions
An initial loading dose of 8 mg/kg body weight, followed thereafter by a maintenance dose of 6 mg/kg body weight administered intravenously every 21 days. Patients may continue until disease progression without clinical benefit, unacceptable AEs or withdrawal of consent.
An initial loading dose of 640 mg, followed thereafter by a maintenance dose of 420 mg administered intravenously every 21 days. Paediatric patients will receive an initial loading dose of 14 mg/kg (maximum 840 mg), followed thereafter by a maintenance dose of 7 mg/kg (maximum 420 mg) administered intravenously every 21 days. Patients may continue until disease progression without clinical benefit, unacceptable AEs or withdrawal of consent.
