Plain English Summary
Background and study aims
Acute respiratory infections (ARTIs) such as cough, sore throat and sinusitis are common, distressing and costly both for individuals and the NHS. Antibiotics have limited benefits in most ARTIs and commonly have side effects. A herbal medicine called Andrographis (Andrographis paniculata) is a promising candidate to treat ARTIs. Andrographis extract is derived from the leaf of the plant Andrographis paniculata. Andrographis is currently used in Western, Ayurvedic and Chinese herbal traditional medicines for respiratory and digestive illnesses. Results from muultiple trials suggests that Andrographis performed better than placebo after 5-7 days. This study aims to investigate the feasibility of carrying out a trial of providing Andrographis capsules to adults who visit their GP with ARTI symptoms, where the GP thinks the symptoms are caused by an infection (bacterial or viral) but NOT pneumonia. It aims to find out whether patients find it acceptable to take the Andrographis capsules, whether enough patients can be recruited into the study, whether the people involved complete the study documents, and how many of the patients complete the study diary after the treatments have been given. The investigators have previously completed interviews with health professionals treating patients in order to understand the issues around herbal medicines for ARTIs, and this has helped us design this feasibility study.
Who can participate?
Patients aged 18 or over who have visited their GP surgery with a sore throat, acute cough (less than 7 days' duration) or cold where pneumonia is not suspected.
What does the study involve?
Participants will be randomly allocated to receive capsules containing 250 mg Andrographis paniculata or placebo (dummy) capsules (capsules that look, taste and smell the same but have no active ingredients) for a week. They will be asked to take 3 capsules 4 times a day with water before food. Treatments will be randomly allocated and double-blinded (meaning that no one, including the doctor and the participant, will know which participant is getting which treatment). Both groups will continue to receive standard care and GPs can prescribe antibiotics if needed to participants in either group, either taken immediately, or issued as a delayed prescription.The GP will decide which antibiotic is prescribed. Participants will be asked to wait 7-10 days before collecting the delayed prescription unless their symptoms show substantial worsening.
What are the possible benefits and risks of participating?
It is not known whether participants will have any additional benefit from taking part in this trial. However their participation will help to give important information about how best to treat people with ARTIs in the future. It is unlikely but participants may experience mild side effects from taking the trial medication.

Scientific title | GRAPHALO: A double blind randomised placebo controlled feasibility study evaluating the effect of Andrographis paniculata (Immunographis) in the treatment of adults with acute respiratory tract infections (ARTIs) |
Study acronym | GRAPHALO |
Study hypothesis | Acute respiratory infections (ARTIs) (such as cough, sore throat and sinusitis) are common, distressing, and costly both for individuals and the NHS. Antibiotics have limited benefits in most ARTIs and commonly have side effects. A herbal medicine called Andrographis (Andrographis paniculata) is a promising candidate to treat acute respiratory tract infections. In a recent systematic review of randomised controlled trials, Andrographis performed better than placebo after 5-7 days. The main objective of this trial is to determine the feasibility of running a full-scale trial of Andrographis paniculata leaf extract in a UK primary care setting. |
Ethics approval(s) | 1. Hampshire B Research Ethics Committee and the Health Research Authority, 22/11/2018, ref: 208314, University of Southampton Ethics and Research Governance Online (ERGO) number: 27851 |
Condition | Acute respiratory tract infections with symptoms such as cough, sore throat, fever and muscle ache where pneumonia is not suspected |
Intervention | This is a multicentre, double-blind placebo-controlled feasibility study of Andrographis paniculata leaf extract. The study aims to recruit 60 participants. Patients will eligible for the trial if they are over 18 years of age and present to their GP with a potential ARTI. Adults 18 years and over presenting with an acute cough (≤7 days' duration) or sore throat as their main symptom and, with symptoms localising to the upper respiratory tract (e.g. runny nose, sneezing, fever, muscle ache), for which non-infective diagnoses are judged very unlikely. Participants will be randomised to 1 week of active treatment using Andrographis capsules or placebo. The capsules contain 250 mg of dried Andrographis paniculata. Participants will take 3 capsules 4 times a day with water before food. Treatments will be randomly allocated and double-blinded so that no one, including the doctor and the participant, will know which participant is getting which treatment. Both groups will continue to receive standard care and GPs can prescribe antibiotics if needed to participants in either group, either taken immediately, or issued as a delayed prescription. |
Intervention type | Supplement |
Primary outcome measure | All of the feasibility timepoints will be evaluated after the study finishes (16 weeks): 1. Feasibility of eligibility criteria, assessed using number of patients included and number excluded (and reasons for exclusion) from the trial recorded in on-site screening logs 2. Feasibility of recruitment (ability to recruit patients into the intervention from those attending primary care) assessed using on-site enrolment record, with monthly rate/site adjusted for site list size. 3. Feasibility of randomisation (willingness to be randomised) assessed using the proportion of eligible patients recruited 4. Retention rate calculated from records of enrolment, withdrawal and completed diaries returned after 2 weeks 5. Intervention compliance assessed using patient-record diary data and returned intervention capsules 6. Suitability of the patient diaries and patients’ willingness to complete them and the importance of telephone/text contact from quantitative data collection - percentage of patients returning completed diaries |
Secondary outcome measures | Rates of antibiotic prescription assessed using the participant's record in the diary of the day they started taking antibiotics, evaluated after the study finishes (16 weeks) |

Overall study end date | 31/08/2019 |
