Enterprise Therapeutics Announces £4 million ($5 million USD) Fundraising

Brighton, UK – 10th November, 2016: Enterprise Therapeutics Ltd, a drug discovery company dedicated to the research and development of novel therapies for the treatment of respiratory diseases, today announced that it has closed a £4 million ($5 million USD) financing. The funding was led by existing investors Epidarex Capital and Imperial Innovations and will be used to accelerate the Company’s three drug discovery projects towards drug candidate selection.

Enterprise Therapeutics is developing novel muco-regulatory therapies for patients suffering with cystic fibrosis (CF), Chronic Obstructive Pulmonary Disease (COPD) and severe asthma. To achieve this, the Company is targeting mechanisms that increase the clearance of mucus or reduce levels of mucus production in order to alleviate the symptoms and complications
associated with respiratory disease.

Commenting on the fundraising, Dr John Ford, CEO, Enterprise Therapeutics, said: “Respiratory disease remains an area of high unmet medical need especially in the area of CF where existing therapies do not treat all patients. This additional funding will allow us to advance our research projects and move closer towards our goal of evaluating the efficacy of muco-regulatory drugs in patients. I look forward to working with the team and our investors in this important next
stage of growth.”

Dr Liz Roper, Investor Director, Epidarex, commented: “Based on excellent achievement of project milestones across all three discovery projects at Enterprise Therapeutics we are providing this additional investment to put the company in a strong position as it continues to progress towards the clinic. We are committed to the novel muco-regulatory approach that
Enterprise is taking to combat respiratory diseases.”

Dr Rob Woodman, Investor Director, Imperial Innovations commented: “Enterprise Therapeutics has made significant progress in the 18 months since Imperial Innovations first invested. We believe that the Company has the potential to become a leading player in respiratory disease.”

Enterprise Therapeutics appoints Dr John Ford as CEO

Brighton, UK – October 17, 2016 – Enterprise Therapeutics Ltd, a drug discovery company dedicated to the research and development of novel therapies for the treatment of respiratory diseases, today announced that it has appointed Dr John Ford as CEO with immediate effect.

Enterprise Therapeutics is developing novel muco-regulatory therapies for patients suffering with Chronic Obstructive Pulmonary Disease (COPD), Cystic Fibrosis (CF), and severe asthma. To achieve this the Company is targeting mechanisms that increase the clearance of mucus or reduces levels of mucus production in order to alleviate the symptoms and complications associated with respiratory disease.

Dr Ford is a successful biotechnology entrepreneur who has co-founded Xention, Ario Pharma and Metrion Biosciences. Recently, he was a member of the Executive Team at Dezima that developed TA-8995 for dyslipidaemia and later sold the company to Amgen in 2015 for up to $1.55b. He obtained his BSc and PhD at the University of Leeds, where he worked on the structure and function of TRP channels. Dr Ford has over 18 years’ ion channel research, drug discovery and drug development experience.

Commenting on the appointment, Dr Peter Finan, Chairman Enterprise Therapeutics, said: “John’s experience in ion channels, drug development, and biotech fundraising position him uniquely to lead Enterprise Therapeutics moving forward. His expertise will complement the existing team and we are thrilled to have him on board.”

Dr John Ford commented: “I am delighted to have joined Enterprise Therapeutics at an exciting time for the company. Respiratory disease remains an area of high unmet medical especially in the area of Cystic Fibrosis where existing treatments do not treat all patients. Our mission is to discover new disease modifying therapies that target the underlying mechanisms of mucus congestion, which will reduce the frequency of lung infections and improve patient quality of life. I look forward to working with the team and our investors in this important next stage of growth.”.

About Cystic Fibrosis (CF)

CF is the most common lethal genetic disease amongst Caucasians with an estimated global patient population of 100,000. The average life expectancy, although improving, is approximately 40 years.

About Chronic Obstructive Pulmonary Disease (COPD)

COPD is a chronic disease characterised by a progressive and irreversible decrease in lung function. Globally, COPD is reported to affect over 300 million people and in 2012 was the world’s third highest killer.

About Severe Asthma

Patients with severe asthma are either refractory or poorly managed by current therapies (including bronchodilators and steroids). Severe asthma patients comprise around 5% of the estimated 300 million asthma sufferers, globally.

Flagellin-induces a hypersecretory phenotype in primary human bronchial epithelial cells, presented at North America Cystic Fibrosis Conference, Orlando, October 2016

The TLR5-agonist flagellin (FLG) is the key protein component of bacterial flagella expressed by a number of organisms including Pseudomonas aeruginosa. The proinflammatory activity of bacterial FLG has been well documented in leukocytes although the effects on airway epithelial function are less clear.

Pharmacological characterisation of TMEM16A regulators, presented at The 13th European Cystic Fibrosis Basic Science Conference, Pisa, Italy, March 2016

TMEM16A was recently identified as a calcium-activated chloride conductance and a key orchestrator of anion secretion in the human airway epithelium (Caputo et al 2008; Schroeder et al 2008; Yang et al 2008). It is now clinically established that promoting anion secretion in the airway leads to enhanced mucus clearance and reduced exacerbation frequency in CF patients and as such TMEM16A represents an important target for the next generation of mucokinetics. Importantly, positive regulators of TMEM16A function will be expected to be of benefit in all CF patients, irrespective of their CFTR mutational status.

Flagellin-induces a hypersecretory phenotype in primary human bronchial epithelial cells, presented at The 13th European Cystic Fibrosis Basic Science Conference, Pisa, Italy, March 2016

A screen of microbial-derived products using a 3D model of the human airway epithelium (bronchospheres) revealed flagellin (FLG) as a potential regulator of mucociliary structure and function. Flagellin, a TLR5-agonist, is the key protein component of bacterial flagella expressed by a number of organisms including Pseudomonas aeruginosa. Considering that mucus plugs in the airways of many cystic fibrosis (CF) patients would be reasonably expected to contain FLG, the epithelium is likely to be chronically exposed to this bacterial protein.
