Description of intervention(s) / exposure
This is a phase I study on the safety of BromAc, where 12 healthy volunteers who are otherwise well and remain in the outpatient setting will receive BromAc as a nebulised aerosol into the respiratory tract once daily for three days, in a dose escalation format.
Dose escalation will be Bromelain 100ug/ml, 150ug/ml or 200ug/ml in combination with Acetylcysteine 20mg/ml. Doses will be increased after every 4 patients, with the first patient receiving dose level 1 (BromAc 100ug/20mg/ml). If safe, dose escalation will occur to the next level based on the number of dose limiting toxicities. Dose escalation to the next level will occur after treatment of 4 patients at each level has been completed at the end of day 3.
BromAc is a product that combines two existing products (Bromelain and Acetylcysteine), along with 0.9% normal saline to be delivered into the respiratory tract via nebulised aerosol delivery through a mask, which will be administered by a nurse or member of the study team. The nebulisation will take approximately 20 minutes. Doses will be administered under clinic monitoring. The participant will be assessed for symptoms and side effects during nebulisation of BromAc and for 2 hours following completion of nebulisation. Clinical observations and a symptom assessment questionnaire will be completed on days 1, 2 and 3 with a blood test at the end of day 3 treatment. Follow up phone calls will occur on days 5 and 10, with a symptom assessment questionnaire.

Outcomes
Primary outcome [1] 328839 0
To characterise and evaluate the safety of BromAc following nebulised delivery: safety will be assessed by the number of moderate to severe adverse events. Possible adverse events include allergy/sensitivity to the drug, bronchospasm, throat dryness or nasal dripping. Participants will be monitored for adverse events in the clinic and by telephone follow up.
Timepoint [1] 328839 0
On days 1, 2, 3 during treatment and post treatment for 2 hours, and during follow up on days 5 and 10
Secondary outcome [1] 400594 0
Proportion of participants with treatment-emergent adverse events (AEs): Possible adverse events include allergy/sensitivity to the drug, bronchospasm, throat dryness or nasal dripping. Participants will be monitored for adverse events in the clinic and by telephone follow up. Participants will also complete a study specific symptom questionnaire following treatment on days 1, 2 and 3 and during follow up on days 5 and 10.
Timepoint [1] 400594 0
On days 1, 2, 3 during treatment and post treatment for 2 hours, and during follow up on days 5 and 10
Secondary outcome [2] 400595 0
Determine the maximum tolerated dose (MTD) of BromAc within the therapeutic range for COVID-19 delivered by nebuliser: toxicity will be assessed by the modified toxicity probability interval (MTPI) design and graded according to the Common Terminology Criteria for Adverse Events criteria
Timepoint [2] 400595 0
On days 1, 2, 3 during treatment and post treatment for 2 hours, and during follow up on days 5 and 10

Can healthy volunteers participate?
Yes
Key exclusion criteria
• Have been in contact with a known case of COVID-19 or advised to undertake self-isolation in the last 14 days
• Have known allergy (anaphylaxis) or sensitivity to pineapples, papain, bromeliads, (fruit or plant) sulphur, eggs or Acetylcysteine that cannot be managed with steroids or antihistamine prophylaxis or any other serious unrelated allergy
• Have symptoms of COVID-19 such as cough or shortness of breath or evidence of pulmonary disease, other respiratory disease including asthma or chronic obstructive pulmonary disease
• Have a coagulation disorder of any kind or are on anticoagulant or anti-platelet therapy, history of nose bleeds or easy bruising
• Have any other serious comorbidities where inclusion in the trial will subject the participant to a higher risk of adverse events
• Pregnant women are excluded from this study because BromAc has unknown but a potential risk for adverse events in nursing infants secondary to treatment of the mother. Breastfeeding should be discontinued if the mother is treated with BromAc
• People with psychiatric illness/social situations that would limit compliance with study requirements
• Are unable to give fully informed and educated consent or are unable to comply with the standard follow up procedures of a clinical trial
