Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Flurbiprofen Oral Lozenge
Treatment: Drugs - Difflam
Treatment: Drugs - Flurbiprofen 8.75 MG

Experimental: Flurbiprofen Oral Lozenge - 30 participants will be asked to suck one (1) flurbiprofen 8.75 mg honey and lemon lozenge (tradename: Strepfen) until dissolved.

Placebo comparator: Placebo lozenge - 30 participants will be asked to suck one (1) non-medicated Difflam Soothing Drops + Immune Support Honey \& Lemon flavour lozenge until dissolved.

Experimental: Flurbiprofen 8.75 MG - 30 participants will be asked to perform three (3) oral actuations (2.91 mg per actuation) of flurbiprofen 8.75mg spray.

Other: Low dose flurbiprofen spray - 30 participants will be asked to perform one (1) oral actuation of flurbiprofen 8.75 mg spray, equivalent to a 2.91mg dosage. This will serve a a low dose control as there is no placebo spray available.


Treatment: Drugs: Flurbiprofen Oral Lozenge
This commercially available, over-the-counter lozenge manufactured by Reckitt Benckiser contains flurbiprofen as the active ingredient and is registered for the short-term treatment of sore throat associated with upper respiratory tract infections in people over the age of 12 years.

Treatment: Drugs: Difflam
This is a non-medicated, control lozenge that is the same flavour as the experimental lozenge that is marketed to help soothe dry, tickly throats while supporting the body's immune health.

Treatment: Drugs: Flurbiprofen 8.75 MG
This commercially available, over-the-counter spray manufactured by Reckitt Benckiser contains flurbiprofen as the active ingredient and is registered for the short-term treatment of sore throat associated with upper respiratory tract infections in people over the age of 12 years. It requires 3 actuations of the spray to deliver the full 8.75 dose. Here, a low dose control can be delivered by only performing 1 actuation of the spray.

Eligibility
Key inclusion criteria
* An onset of any 2 URTI symptoms in past 3-5 days, such as a sore throat, fever, coughing, coughing up phlegm, sneezing, and runny nose;
* A current cough or urge-to-cough rated at least 5 in severity and/or ranking cough as subject's most bothersome symptom on Cold Symptoms Questionnaire (CSQ);
* A feeling of sickness interfering with their daily life, rated as at least mildly;
* A cough consistent with acute cough - i.e., cough onset with URTI and not ongoing, chronic cough;
* Written informed consent and a willingness and ability to comply with the study protocol.
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
* A pre-existing chronic lung disease (asthma, COPD, chronic bronchitis etc), to exclude these as causes for cough;
* The use of inhaled or systemic steroids / broncho-active medication, ACE inhibitors, oral or inhaled antihistamines, opiates, gabapentin, tricyclic antidepressants (current or within the past 3 months), as these will alter airway inflammatory profiles and/ or cough sensitivity;
* A current cigarette or marijuana smoker/vaper, recreational drug user, or have given up smoking/vaping within the last 12 months, or a former smoker with greater than 20 pack-years, alter airway inflammatory profiles and/ or cough sensitivity;
* Pre-existing chronic cough (cough persisting for more than 8 weeks): unexplained chronic cough (UCC) or refractory chronic cough (RCC) associated with or without a pre-existing condition (GERD, rhinitis, etc), as we are studying acute cough;
* Prior experience of an allergic or bad reaction to capsaicin or chilli (which is rare);
* Prior experience an allergic or bad reaction to a non-steroidal anti-inflammatory drug (NSAID) such as ibuprofen;
* Ongoing or history of stomach ulcer, impaired kidney or liver function, or heart failure;
* Pregnancy, lactation or actively trying to become pregnant;
* Currently taking other products with flurbiprofen, aspirin or other anti-inflammatory medicines;
* Evidence of COVID-19 positivity, either during the COVID Rapid Antigen Test administered on the day of assessment or have informed us that they have become positive in the 24-48 hours after the testing session (i.e., participants who were likely positive during assessment but under the detection threshold);
* Participants who cannot provide informed voluntary consent.
