MoST Addendum 12
Linked study record
This record is an addendum to the MoST framework (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 linked to ACTRN12616000908437.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive 2 drugs, vemurafenib and cobimetinib. Both drugs, in the format of tablet, are to be taken orally by participants, at a dose of 960mg twice daily (days 1 to 28 in a 28-day cycle) for vemurafenib and at 60mg daily (days 1 to 21 in a 28-day cycle) for cobimetinib.

If participants experience intolerance toxicity, vemurafenib dosage may be reduced to 720mg twice daily, and then to 480mg twice daily if participants experience further intolerance toxicity. For cobimetinib, the dosage may be reduced to 40mg daily for first event of intolerance toxicity and then to 20mg daily if participants experience further intolerance toxicity.

Participants will receive both vemurafenib and cobimetinib treatments until disease progression is documented or when the participants experience intolerable toxicity or withdraws for another reason. Participants will be asked to return unused drug and empty drug containers at each return visit. The Pharmacy Department at participating institutions will maintain a record of drugs dispensed for each participant.

Outcomes
Primary outcome [1] 324094 0
The primary end point for metastatic NSCLC is disease control and it is defined as the objective tumour response, based on complete or partial response using cancer specific response criteria. Where disease evaluation is not based on imaging scans (eg. CT), clinical assessment of response may be utilised. Response is assigned based on investigator discretion.
Timepoint [1] 324094 0
Imaging (eg. CT) scans for disease evaluation will take place every 8 weeks from first dose of study treatment until disease progression or commencement of non-protocol anti-cancer therapy, whichever occurs first.
Primary outcome [2] 324098 0
The primary end point for other cancers is disease control defined as: 1. Objective tumour response, based on complete and partial responses using cancer specific response criteria. Where disease evaluation is not based on imaging scans (eg. CT and MRI), biomarker-based or qualitative clinical assessment of response may be included, such as European Leukemia Net (ELN) guidelines for acute myeloid leukemia (AML), Gynecologic Cancer Intergroup (GCIG) and Prostate Cancer Working Group 3 (PCWG3) criteria will be employed. These data will be collected from participant 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.
Timepoint [2] 324098 0
Imaging (eg. CT) scans for disease evaluation will take place every 8 weeks from first dose of study treatment until disease progression or commencement of non-protocol anti-cancer therapy, whichever occurs first.
Secondary outcome [1] 383742 0
Overall survival (OS) (death from any cause)
Timepoint [1] 383742 0
For the duration of the study. From the date of registration to date of death from any cause, or the date of last known follow-up alive.
Secondary outcome [2] 383743 0
Progression free survival (PFS). PFS is defined as the interval from date of registration to the date of first evidence of disease progression or death from any cause, whichever occurs first. Participants who did not progress or die will be censored on the date of their last clinical assessment or tumour assessment. Disease progression is defined according to RECIST v1.1, RANO guidelines, or disease specific guidelines.
Timepoint [2] 383743 0
Imaging (eg. CT) scans for disease evaluation will take place every 8 weeks from first dose of study treatment until disease progression or commencement of non-protocol anti-cancer therapy, whichever occurs first.
Secondary outcome [3] 383744 0
Time to treatment failure. This is defined as the interval from the date of registration to date of permanently ceasing study treatment for any reason. The entered data in the trial database will be used to evaluate this outcome. Participants who are still on study treatment at time of analysis will be censored on the date of their last reported study treatment.
Timepoint [3] 383744 0
Time to treatment failure analysis is performed at 12 months from last patient registration.
Secondary outcome [4] 383745 0
Depth and duration of response according to RECIST 1.1
Timepoint [4] 383745 0
Imaging (eg. CT) scans for disease evaluation will take place every 8 weeks until disease progression or commencement of non-protocol anti-cancer therapy, whichever occurs first.
Secondary outcome [5] 383746 0
Progression Free Survival (PFS) at 6 months. PFS is defined as the interval from date of registration to the date of first evidence of disease progression or death from any cause, whichever occurs first and is the proportion of participants on study who are alive and progression free at 6 months. The disease progression is defined according to RECIST v1.1, RANO guidelines, or disease specific guidelines.
Timepoint [5] 383746 0
At 6 months post participant registration via CT, MRI or PET (with CT function) scans of disease evaluation
Secondary outcome [6] 383747 0
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. Reported AEs (eg. diarrhoea, gastrointestinal disorder) by participants will be documented by study site staff and subsequently transcript 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.
Timepoint [6] 383747 0
Adverse events will be recorded from the first dose of study treatment until 30 days after cessation of study treatment.
Secondary outcome [7] 383748 0
Health related quality of life during treatment will be assessed using the EORTC QLQ-C30 and The Brief Pain Inventory Forms
Timepoint [7] 383748 0
Every 4 weeks from first dose of study treatment until end of treatment. Subsequently, at every 8 weeks until disease progression
Secondary outcome [8] 428477 0
Time to progressive (TTP) 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 (pan-cancer/solid tumour cohort only).
Timepoint [8] 428477 0

Safety/efficacy
Statistical methods / analysis
A group of 64 patients harbouring a BRAF V600 mutation will be recruited for 4 substudies containing 16 participants each. Two substudies (32 participants) are for patients with pathologically confirmed metastatic non-squamous NSCLC and the other 2 substudies (32 participants) are for patients with solid tumour of any histologic type.

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.
