Outcome Measures
Primary Outcomes (1)
Adherence with NIV
Defined as using NIV \> 4 hours/day during the NIV treatment period.
Change during the acclimatization period (~3 weeks) and during the NIV treatment period (~7-8 weeks) (approx. 10 weeks total per participant).
Secondary Outcomes (25)
Intolerance of NIV
Change during the acclimatization period (~ 3 weeks) and during the NIV treatment period (~7-8 weeks) (approx. 10 weeks total per participant).
Respiratory function
During the baseline (~week 0) and during the follow-up assessment (~ week 3 + 7). Cohort: At 3, 6 and 12 months following RCT commencement as able.
Maximal inspiratory/expiratory pressure
During the baseline (~week 0) and during the follow-up assessment (~ week 3 + 7). Cohort: At 3, 6 and 12 months following RCT commencement as able.
Sniff nasal pressure
During the baseline (~week 0) and during the follow-up assessment (~ week 3 + 7). Cohort: At 3, 6 and 12 months following RCT commencement as able.
Arousal index (during polysomnography)
During the baseline (following the ~3 week acclimatisation period) and during the follow-up assessment (~ week 3 + 7). Cohort: Not Collected.
- +20 more secondary outcomes
Other Outcomes (1)
Arterial Blood Gas (ABG) (during polysomnography)
RCT: During the baseline (following the acclimatisation period) and during the follow-up assessment. Cohort: Not Collected.

Intervention
EXPERIMENTALThis trial of PSG-assisted commencement of non-invasive ventilation (NIV) in motor neurone disease (MND) follows the methodology of our previous single-site study (Hannan et al 2019 ERJ), with the addition of an open label cohort that extends until (the earlier of) 12 months or death. After empirical NIV set-up and an acclimatisation period (3 weeks), participants will undergo single night in-laboratory polysomnography (PSG). The PSG will be performed and supervised by a sleep scientist. In the intervention group, the "intervention" PSG results will be used to adjust/titrate NIV settings to optimize ventilation and improve synchrony between the patient and the NIV device. Participants will be asked to continue to use NIV as prescribed for the subsequent 7 week intervention period.
Control
PLACEBO COMPARATORThe participants allocated to the control group will also be asked to attend a single night in-laboratory PSG. The NIV settings will not be adjusted throughout the PSG ("sham" PSG). Participants in the control group will retain their original settings after the sham PSG, and will be asked to continue to use NIV in this manner for the subsequent 7 week intervention period.

- Masking Details
- The attending sleep scientist will refer to a database that reveals (statistician-generated) participant's treatment allocation. The sleep scientist will not reveal the treatment allocation to the Clinical team, Research team or the participant. Centralised allocation concealment will be ensured through the Adept/REDCap trial database.
