Description of intervention(s) / exposure
RESPONSE: Doubling the dose has been explained in following the text from the protocol page 6, Telephone Call:
"One week after starting each treatment, participants will be contacted by telephone to enquire about possible adverse effects to the study medication including dizziness/light-headedness, falls, worsening of respiratory symptoms. If necessary a clinic visit will be arranged to assess these symptoms.
If no symptoms or only minor symptoms have been reported, the participants is willing and it is judged safe to increase the beta-blocker dose, participants will be instructed to double the dose of beta-blocker (taking 2 tablets each morning). If there are concerns about increasing the dose, but the participant is willing to continue in the study, the same dose can be continued (i.e. 2.5mg bisoprolol, 12.5mg carvedilol or matching placebo)."

Eligible participants will undergo baseline measurements before an open-label test dose of ß–blocker (carvedilol 12.5mg).
Participants who tolerate the test dose will be randomised to one of 6 treatment regimens,
a. Placebo inhaler and placebo tablet
b. Placebo inhaler and carvedilol 12.5mg/25mg
c. Placebo inhaler and bisoprolol 2.5mg/5mg
d. Umeclidinium/vilanterol 62.5/25mcg inhaler and placebo tablet
e. Umeclidinium/vilanterol 62.5/25mcg inhaler and carvedilol 12.5mg/25mg
f. Umeclidinium/vilanterol 62.5/25mcg inhaler and bisoprolol 2.5mg/5mg

Treatment (inhaler and tablet) will be administered once per day in the morning. Each treatment arm lasts for 14 days, however 7 days after starting each treatment, participants will be contacted by telephone to enquire about possible adverse effects to the study medication including dizziness/light-headedness, falls, worsening of respiratory symptoms. If necessary a clinic visit will be arranged to assess these symptoms.

If no symptoms or only minor symptoms have been reported, the participant is willing and it is judged safe to increase the beta-blocker dose, participants will be instructed to double the dose of beta-blocker (taking 2 tablets each morning). If there are concerns about increasing the dose, the participant may continue in the study at the same dose (i.e. 2.5mg bisoprolol, 12.5mg carvedilol or matching placebo) at the discretion of the PI and / or the participant is willing to continue.

There will be no washout periods between each arm.

Randomised participants will receive the next treatment pack in a consecutive sequence prepared in accordance with the randomisation schedule. Participants and Investigators will be blinded to the intervention order in the cross-over trial. All investigational drugs will be placebo-matched so the participant and investigators are unaware of the active drugs.

At each treatment arm visit, participants will return ALL their study medication for compliance and reconciliation. Safety procedures will include spirometry testing (1, 2 and 3 hrs post dose), ECG, BP and 6 minute walk test (between 2 and 3 hours post dose). A questionnaire will be completed to reflect the symptoms of the last week.

After completing all 6 treatment arms, the study will be complete.

Efficacy
Statistical methods / analysis
In our previous study of formoterol in COPD patients the paired standard deviation for FEV1 was 180mL. The minimally clinically important difference in FEV1 in patients with COPD is 100mL. To achieve 80% power, with alpha 0.05 (two-sided), we need 28 participants in a paired design. We aim to recruit 36 participants to allow for up to a 20% withdrawal rate
