- Brief 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.
- Detailed Description
DETERMINE Treatment Arm 04: Trastuzumab in combination with pertuzumab in Adult, Paediatric and TYA patients with rare\* cancers with HER2 amplification or activating mutations and in common cancers where HER2 amplification or activating mutations are 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 trastuzumab and pertuzumab 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 End of Treatment (EoT).
After completion of study treatment, patients are followed up every 3 months for 2 years.

An OR is defined as the confirmed occurrence of either a Complete Response (CR) or Partial Response (PR) according to Response Evaluation Criteria in Solid Tumours (RECIST) Version 1.1 criteria (or immune related \[ir\]-RECIST or standard imaging criteria for specific disease e.g. Response Evaluation in Neuro Oncology criteria \[RANO\]. In patients with leukaemia, OR will be defined as the occurrence of CR, CRi (CR incomplete neutrophil recovery) or CRp (CR with incomplete platelet recovery). The trial will report the proportion of patients with an OR and 95% credible interval.
Durable Clinical Benefit (DCB) Disease assessments to be performed up to 24 weeks from the start of trial treatment. DCB is defined as the absence of disease progression for at least 24 weeks from the start of trial treatment according to RECIST Version 1.1 criteria (or ir-RECIST or standard imaging criteria for specific disease e.g. RANO criteria) and, where relevant (e.g. for haematological malignancies), by standard bone marrow response assessment criteria. Alternative definitions of DCB based on different time points may be pre-specified for particular sub-cohorts if 24 weeks is not clinically relevant. The trial will report the proportion of patients with a DCB and 95% credible interval.
- Secondary Outcome Measures

EORTC-QLQ-C30 Standardised Area Under Summary Score Curve (QLQSAUC) in adult patients QoL surveys performed prior to inclusion, every cycle (each cycle is 21 days) and at EoT visit (up to 5 years). For adult populations, multiple measures of Quality of Life (QoL) will be generated from patient completion of the European Organisation for Research and Treatment of Cancer QLQ-C30 (EORTC-QLQ-C30) questionnaire (15 measures). For each patient the Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean QLQSAUC and 95% credible interval.
EQ-5D Standardised Area Under Index Value Curve (EQ5DSAUC) in adult patients QoL surveys performed prior to inclusion, every cycle (each cycle is 21 days) and at EoT visit (up to 5 years). For adult populations, two measures of QoL will be generated from patient completion of the EQ-5D-5L questionnaire.
