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.

Study type
Description of intervention(s) / exposure
Participants will receive 2 drugs:
1/ Durvalumab, that will be given to participants via intravenous infusion by a qualified administrator at a dose of 1500 mg every 4 weeks
2/ Acalabrutinib in the form of a tablet taken orally by participants at a dose of 100mg twice daily.

The durvalumab may be withheld, whereas acalbrutinib dosage may be reduced to 100mg once daily if participants experience intolerable toxicity. If a further acalabrutinib dose reduction is required, participants should discontinue acalabrutinib.

Participants will receive both durvalumab and acalabrutinib treatments until disease progression is documented or when the participants experience intolerable toxicity or withdraw 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.

Secondary outcome [5] 388816 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 by participants will be documented by study site staff and subsequently transcribed onto the study electronic data capture (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 [5] 388816 0
Adverse events will be recorded from the first dose of study treatment until 30 days after the cessation of study treatment.

Every 4 weeks from first dose of study treatment until participants stop treatment due to intolerable toxicity or withdraw for another reason (apart from disease progression). After treatment discontinuation, the health-related quality of life will be assessed at every 8 weeks until disease progression is recorded.

Key inclusion criteria
1. Adults aged 18 years and older, with high grade B cell lymphoma or transformed low-grade B cell lymphoma that is refractory to, or relapsed following standard chemotherapy or radiation therapy.

Statistical methods / analysis
A group of 32 patients with high grade B cell lymphoma will be treated with durvalumab and acalabrutinib. For a sample size of 32 patients, we would conclude that the durvalumab and acalabrutinib combination demonstrates a promising signal of activity if 8 or more patients have a complete or partial response at 6 months.

A post-hoc analysis of tertiary and correlative outcomes will be conducted by correlating objective response against potential biomarkers, including but not limited to PD-L1 expression levels, and/or TMB

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.

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 clinical activity of the combination of durvalumab and acalabrutinib in participants with high grade B cell lymphoma.

Who is it for?
You may be eligible to join the study if you are aged 18 years and older, with high grade B cell lymphoma.

Study details:
Participants will receive 2 drugs: 1/ durvalumab, to be administered via intravenous infusion at a dose of 1500mg every 4 weeks, and 2/ acalabrutinib, to be administered orally at a dose of 100mg twice daily. Both drugs will be given to participants continuously as long as they and their doctor agree there is a benefit from treatment. Participants will undergo clinical assessments at 4 weekly intervals from first treatment until end of treatment, then 8 weekly intervals until disease progression. Imaging will be at 8 weekly intervals until disease progression. Safety and tolerability of treatment will be assessed at 4 weekly intervals. Health related quality of life during treatment will be assessed at 4 weekly intervals and then every 8 weeks after end of treatment until progression.

We cannot guarantee that participants will receive any benefits from this study. This study is being carried out to improve the way we treat cancer patients who have limited treatment options available to them. It is hoped that the combination of durvalumab and acalabrutinib will be well tolerated and will improve outcomes for future patients, however there may be no clear benefit from participation in this study.
