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.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A group of 16 patients will be treated with Entrectinib. Entrectinib will be administered orally at a dose of 600 mg, once daily from days 1-28 on a 28-day treatment cycle until disease progression is documented, the patient experiences an intolerable toxicity, or withdraws for another reason. Clinical assessments will continue until disease progression if treatment is stopped for toxicity. Unacceptable toxicity is determined by the patient or site investigator or defined according to study protocol.

Participants will be followed up for at least 30 days after end of treatment for new adverse events and to follow up any adverse events which are ongoing at the end-of-treatment visit.
Patients will be followed up for disease progression, overall survival or subsequent anticancer
treatments at 8 weekly intervals until progression (if treatment stopped for reasons other than progression) and at 12 weekly intervals post progression.

Participant medication compliance will be determined at each clinic visit by return pill count.

Phase 2
Type of endpoint/s
Statistical methods / analysis
A group of 16 patients will be recruited. 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.
