Primary endpoint met; RPL554 produced clinically and statistically significant improvements in lung function at all dose levels
Clinically relevant secondary endpoints were also met, including statistically significant, progressive improvements in COPD symptoms
RPL554 was well tolerated at all dose levels in this four week 400 patient study

The study met its primary endpoint, with RPL554 producing a clinically and statistically significant improvement in peak forced expiratory volume in one second (FEV1) at four weeks in patients with moderate-to-severe COPD compared to placebo. Furthermore, the peak FEV1 was significantly improved at all time points over the four weeks of dosing. Secondary endpoints measuring 12 hour average FEV1, COPD symptoms and Quality of Life were also met and support the potential clinical benefits of RPL554 for the treatment of COPD.
The four-week, double-blind, placebo-controlled, parallel group, Phase 2b multicenter European study performed in the out-patient setting evaluated the efficacy, safety, and dose-response of nebulized RPL554 administered twice-daily as a maintenance treatment for COPD in 403 patients with moderate-to-severe COPD. There were four dosing arms of RPL554 (0.75 mg, 1.5 mg, 3.0 mg and 6.0 mg) in the study in addition to placebo and patients were required to withhold use of regular long-acting bronchodilator therapy for the duration of the study.
Secondary endpoints include:

“These results are very encouraging and strongly support the progression of RPL554 into later stage development as an inhaled treatment for COPD patients”, said
In previous clinical trials, RPL554 has been observed to result in bronchodilator effects when used alone or as an add-on treatment to other COPD bronchodilators. It has shown clinically meaningful and statistically significant improvements in lung function when administered in addition to frequently used short- and long-acting bronchodilators, such as tiotropium (Spiriva®), compared with such bronchodilators administered as a single agent. In addition, RPL554 has shown anti-inflammatory effects in a standard challenge study with COPD-like inflammation in human subjects. In these studies, RPL554 has been well tolerated. RPL554 also has a favorable safety and tolerability profile, having been administered in more than 730 subjects in 12 clinical trials.

Chronic obstructive pulmonary disease (COPD) is a progressive and life-threatening respiratory disease for which there is no cure.1 The condition damages the airways and the lungs, leading to persistent breathlessness, impacting a person’s daily life and their ability to perform simple activities such as walking a short flight of stairs or carrying a suitcase.1 Although COPD is thought to be underdiagnosed, globally, around 384 million people suffer from the disease.2 This number, according to the

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 the value of the top-line results from the Phase 2b clinical trial, RPL554 as a new complementary treatment for patients with COPD, projected annual medical costs related to COPD, the results of the Phase 2b trial supporting later stage development of RPL554, the future clinical development and positioning of RPL554, and the treatment potential for RPL554.
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.
