Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
CYCLE 1- DAY 1
FL: Day 1: 1000mg dose, commence at 50mg/hr, increment by 50mg/hr every 30 mins (max400mg/hr)
CLL: Day 1: 100mg dose at 25mg/hr followed by
Day 2: 900mg dose, commence at 50mg/hr, increment by 50mg/hr every 30 mins (max 400mg/hr


CYCLE 1- DAY 8
FL & CLL: 1000mg dose, commence at 100mg/hr, increment by 100mg/hr every 30mins (max 400mg/hr)
CYCLE 1- DAY 15
FL & CLL 1000mg dose, commence at 100mg/hr, increment by 100mg/hr every 30 mins (max 400mg/hr)

CYCLE 2 onwards
Standard infusion protocol -If patient experiences any grade 3 or 4 IRR during cycle 1 (or does not consent)
Commence at 100mg/hr, incrementing by 100mg/hr every 30 minutes (max 400mg/hr) (4-hour infusion time)

Rapid Infusion Protocol 90mins (intervention arm) from cycle 2 onwards
If maximum of grade 2 reaction during cycle 1
Fixed rate – 90 minutes (666mg/hr)

Treatment cycles vary in length according to chemotherapy backbone.
O-CHOP21, O-CVP = 21 day cycle with Obinutuzumab given on Day 1 of the cycle
O-acalabrutinb, O-Venetoclax, O-Chlorambucil, O-Bendamustine= 28 day cycle with Obinutuzumab given on Day 1 of the cycle
Obinutuzumab maintenance = 56 day cycle with Obinutuzumab given on Day 1 of the cycle

CLL patients will be treated for 6 cycles with Obinutuzumab
FL patients will be treated for 6 cycles then proceed onto maintenance for 2 years.
Intervention code [1] 328907 0
Treatment: Drugs
Comparator / control treatment
Active control
CYCLE 2 onwards
Standard infusion protocol -If patient experiences any grade 3 or 4 IRR during cycle 1 (or does not consent)
Commence at 100mg/hr, incrementing by 100mg/hr every 30 minutes (max 400mg/hr) (4-hour infusion time)

Active

Outcomes
Primary outcome [1] 338632 0
Rates of infusion reactions
Timepoint [1] 338632 0
Every infusion on both the intervention arm and standard infusion arm will be assessed for adverse reactions, with special focus on Infusion related reactions for a period of 12 months or until number of infusions have been met to meet statistical significance.



Sample size and statistical power
Alpha value= 0.05
Beta value = 0.8
Variance = 20%
Sample size estimate would be 128 infusions.
Secondary outcome [1] 436737 0
Nurse acceptance
Timepoint [1] 436737 0
The nurses will only complete one survey at the end of their first intervention infusion rate.

Phase
Phase 4
Type of endpoint/s
Safety
Statistical methods / analysis
Logistic regression testing for Odds Ratio (OR) of reaction comparing the two cohorts of, retrospective and prospective obinutuzumab infusions. Patients previously treated in Cairns with Obinutuzumab will be compared to trial patients for rates of reactions. Other listed variables will be adjusted for confounding affect such as age, pre-treatment lymphocyte count, other chemotherapy or targeted therapy given in combination. Coefficients will be assigned to predictor variables, such cancer type and steroid dose for outcome variable.

Nursing surveys will be analysed with descriptive statistics of frequency and median level of acceptance and confidence in the administration process. T-Test and ANOVA will compare response rate between level of experience and level of acceptance to identify significant differences.
