Linked study record
This record is an addendum to the MoST framework protocol (ACTRN12616000908437). The MoST framework protocol consists of 1/molecular screening (genomic analysis to determine whether participants are suitable for a sub-study) and 2/ sub-study design structure (study treatment for specific genomic expression/participant population). Additionally, the sub-study shares the same study objectives and outcomes as the framework. Hence, this is a substudy that is linked to ACTRN12616000908437.

Outcomes
Primary outcome [1]
320919
0
The primary end point is disease control defined as:
1. Objective tumour response, based on complete and partial responses using cancer specific response criteria or
2. Time to progressive disease exceeds the documented time to progressive disease on the last treatment prior to substudy entry by at least 1.3 times (TTP2/TTP1 > 1.3). Or exceeds 6 months if TTP1 is not evaluable.
Where disease evaluation is not based on CT scans alternative validated guidelines, such as Gynecologic Cancer Intergroup (GCIG) and Prostate Cancer Working Group 2 (PCWG2) criteria will be employed.
Where radiological progression cannot be assessed, evidence for clinical progression will be documented. These data will be collected from patient questionnaires, such as quality of life per the QLQ-C30 version 3 or The Brief Pain Inventory, or clinical reports to supplement the primary outcome.

Safety and tolerability of treatment (rates of adverse events). All adverse events (AEs), including event grading as per NCI CTCAE criteria, will be captured from the first dose of study treatment until 30 days after cessation of study treatment. AEs reported by participants will be documented by study site staff and subsequently transcribed onto study electronic data capturing (EDC) system. In order to evaluate the safety and tolerability of the study treatment, the entered AE types, frequency and severity in the EDC will be analysed.

Statistical methods / analysis
A group of 64 patients will be recruited for 4 substudies containing 16 subjects each.
Subjects in group 1 will have tumours with activating HER2 mutations in treatment-refractory solid cancers (recruitment complete).
Subjects in group 2 will have tumours with HER2 amplifications in the absence of a HER2 mutation in treatment-refractory solid cancers (recruitment complete).
Subjects in group 3 and 4 will have HER2 activating mutation with/without amplification in metastatic non-squamous NSCLC.
As described in the framework protocol (ACTRN12616000908437), substudies with greater than or equal to 3 out of 16 responding patients, will in general be sufficiently interesting to investigate further. As a general rule, substudies with less than 3 out of 16 responses will be considered to not support the molecular hypothesis behind the substudy.
If some activity is recognised in a 16 patient substudy cohort but further information is needed to inform development of phase II testing, iterative substudies may be opened to enrich for patients that harbour a specific common biomarker or histologic cancer subtype. Each such iteration would constitute a new substudy for the purposes of this framework.
The sample size and guiding definitions of what constitutes an interesting signal are determined empirically as the investigators considered these numbers of patients as sufficient for signal-seeking purpose.

Summary
Brief summary
This is a substudy of the Cancer Molecular Screening and Therapeutics (MoST) Program, which is registered on ANZCTR with ID ACTRN12616000908437. This substudy will evaluate the activity of trastuzumab emtansine (T-DM1) in patients with advanced tumours with HER2 amplification or mutations. Who is it for? You may be eligible to join the study if you are aged 18 years and older with either; a. advanced and/or metastatic solid tumour of any cell type that is no longer responding to treatment or unsuitable for standard therapies for that cancer type, or b. metastatic, non-squamous, non-small cell lung cancer (NSCLC) Participants will have tumours with HER2 alterations Study details Participants will continue to receive T-DM1 intravenously at a dose of 3.6 mg/kg every 21 days continuously as long as they and their doctor agree there is a benefit from treatment. Participants will undergo imaging assessments at 9 weekly intervals or as clinically indicated in order to evaluate tumour response. Safety and tolerability of treatment and health related quality of life during treatment will be assessed at 3 weekly intervals. We cannot guarantee that patients will receive any benefits from this study. This study is being carried out to improve the way we treat cancer patients who may have limited treatment options available to them. It is hoped that T-DM1 will be well tolerated and will improve outcomes for future patients, however, there may be no clear benefit from participation in this study.
