Achieved significant and clinically meaningful additional improvement in peak lung function and faster onset-of-action when added to tiotropium
Demonstrated statistical significance across all primary and secondary efficacy outcome measures, at 6 mg dose; a clear dose response compared to 1.5 mg dose

This was a double blind, placebo-controlled, three way cross-over trial in 30 subjects with COPD and included two different doses of RPL554, 1.5 mg and 6 mg, or placebo, dosed twice-daily for three days, in addition to tiotropium, a long-acting anti-muscarinic (LAMA) bronchodilator, dosed once daily (ClinicalTrials.gov Identifier: NCT03028142). The primary outcome measures for the trial were peak forced expired volume in one second (FEV1) on the third day of dosing and the average FEV1 on the third day of dosing, representing measures of lung function and duration of effect. A number of secondary outcome measures were also recorded. Of note, the 6 mg dose of RPL554 achieved statistical significance, compared to placebo, on all primary and secondary outcome measures. The data confirmed dose dependency between the two RPL554 doses.
• Primary outcome measures 1 :
• Secondary outcome measures:
• Both doses of RPL554 were well tolerated as add-on treatments to tiotropium.
1 In the study, a p-value<0.05 is regarded as statistically significant
2 Defined as FEV1 improvement by ≥10%
3 Dyspnea (shortness of breath) in COPD patients is often associated with hyperinflation of the lungs resulting from a higher residual volume of air
"We are pleased that RPL554 demonstrated a significant and clinically meaningful improvement in lung function of COPD patients and speeds up onset of action when it is administered as an add-on treatment to one of the most widely prescribed LAMA bronchodilators in these patients. LAMAs are the mainstay of all regimens under the GOLD4 treatment guidelines. We observed a clear dose response with the 6 mg dose, achieving statistical significance on all of the primary and secondary endpoints," said
RPL554 is a first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 designed to have anti-inflammatory as well as bronchodilator properties, and is currently in development for the maintenance treatment of COPD patients and for the treatment of patients with cystic fibrosis.
In previous clinical trials, RPL554 has been observed to result in bronchodilatory effects when used alone or as an add-on treatment to other COPD bronchodilators. These trials have shown clinically meaningful and statistically significant improvements in lung function when RPL554 is added to two commonly used bronchodilators, as compared to the improvements in lung function when either bronchodilator is administered as a single agent. RPL554 has also shown anti-inflammatory effects in a standard challenge study with COPD-like inflammation in human subjects. In these studies, RPL554 has been well tolerated.

About Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease for which there is no cure. The condition damages the airways and the lungs, leading to cough, mucus secretion and shortness of breath, impacting a person's ability to perform daily activities. According to the
This press release contains forward-looking statements. All statements contained in this press release that do not relate to matters of historical fact should be considered forward-looking statements, including, but not limited to, statements regarding RPL554’s ability to treat dyspnea, RPL554’s potential to make a meaningful difference in and be a valuable addition to the treatment of COPD patients, and RPL554’s potential to improve lung function when administered as an add-on treatment with bronchodilators..
These forward-looking statements are based on management's current expectations. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from our expectations expressed or implied by the forward-looking statements, including, but not limited to, the following: our limited operating history; our need for additional funding to complete development and commercialization of RPL554, which may not be available and which may force us to delay, reduce or eliminate our development or commercialization efforts; the reliance of our business on the success of RPL554, our only product candidate under development; economic, political, regulatory and other risks involved with international operations; the lengthy and expensive process of clinical drug development, which has an uncertain outcome; serious adverse, undesirable or unacceptable side effects associated with RPL554, which could adversely affect our ability to develop or commercialize RPL554; potential delays in enrolling patients, which could adversely affect our research and development efforts; we may not be successful in developing RPL554 for multiple indications; our ability to obtain approval for and commercialize RPL554 in multiple major pharmaceutical markets; misconduct or other improper activities by our employees, consultants, principal investigators, and third-party service providers; material differences between our “top-line” data and final data; our reliance on third parties, including clinical investigators, manufacturers and suppliers, and the risks related to these parties’ ability to successfully develop and commercialize RPL554; and lawsuits related to patents covering RPL554 and the potential for our patents to be found invalid or unenforceable.
