Project overview

Chronic obstructive pulmonary disease (COPD) is a common lung condition that causes breathing problems and limits airflow. It affects millions of people worldwide and is a leading cause of illness and death. In the UK alone, there are around 3 million people with COPD, and it costs the NHS hundreds of millions of pounds each year. One major complication of COPD is acute exacerbations, which are sudden worsening of symptoms that need extra treatment. These flare-ups are often triggered by infections, like bacteria or viruses, and they can be serious, leading to hospitalisations and even death. Currently, antibiotics are commonly used to treat these flare-ups, but they're not always necessary and can contribute to antibiotic resistance.

To address this issue, researchers are exploring alternative treatments, such as herbal medicines. One herbal medicine called Shufeng Jiedu® (SFJD) has shown promise in treating respiratory infections in China. It contains eight Chinese herbs traditionally used for respiratory conditions. Studying SFJD in UK primary care could help determine if it's a safe and effective alternative to antibiotics for COPD flare-ups, potentially reducing unnecessary antibiotic use and improving patient outcomes.

The project includes three key parts: 1). An Ex vivo study, with an overall aim to investigate the antimicrobial properties of Shufeng Jiedu (SFJD) on NTHi in a lung explant model of infection. 2). EXCALIBUR: A phase 3 double-blind, placebo controlled randomised feasibility trial, to determine the feasibility of conducting a fully powered trial of SFJD as an addition to antibiotics for the treatment of acute exacerbations of COPD in the UK primary care setting. 3). Evidence synthesis and Traditional Herbal Registration.

Research interests

  • Gareth Griffiths is Professor of Clinical Trials and directs our Southampton Clinical Trials Unit.  He works with clinicians, research groups and other scientists in the development of important clinical trials and other well-designed studies that aim to improve the treatment of a range of cancers and other diseases, and early diagnosis of cancer.
  • His works spans the different phases of clinical trials, from small dose finding and safety studies involving a handful of patients to larger trials of hundreds of patients looking at whether the treatments are better than the current standard treatments.  His early diagnosis studies include thousands of patients looking at new ways to detect cancer early.  Ultimately, these studies could help change the way that patients are treated for the better, by creating the evidence so as the new treatments becomes the standard of care for future patients treated in the NHS.
  • Phase I-III clinical trials
