Funding/partnership was always on the cards.
Verona Pharma is to take lung drug RPL554 into late clinical development after a successful phase 2b trial.
Shares in the UK biotech jumped by as much as 12% at one point yesterday following the announcement – Verona already had strong support from analysts, with the likes of N+1 Singer and Jeffries giving “strong buy” and “buy” ratings respectively.
Top-line data show that RPL554 produced clinically and statistically significant improvements in lung functions at all dose levels in chronic obstructive pulmonary disease (COPD).
There is a pressing need for new therapies for COPD, which sees patients’ lung function steadily decline.
Sudden hospitalisations caused by the disease place a major strain on patients, their families, and the health system, and as yet no-one has found a drug that halt the disease’s progress.
The trial was testing RPL554, a first-in-class, inhaled, dual inhibitor of the enzymes phosphodiesterase 3 and 4 with bronchodilator and anti-inflammatory properties, as a maintenance treatment for COPD.
RPL554 produced a clinically and statistically significant improvement in peak forced expiratory volume (FEV1) in one second at four weeks in patients with moderate-to-severe COPD compared with placebo.
The peak FEV1 was significantly improved at all time points over four weeks of dosing, and secondary endpoints measuring 12 hour average FEV1, COPD symptoms and quality of life were also met.
The four-week, double-blind, placebo-controlled, parallel group, phase 2b multicentre European study performed in the out-patient setting evaluated the efficacy, safety, and dose-response of nebulised 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 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.
Verona said the results support the “potential clinical benefits of RPL554 for treatment of COPD.”
Phase 3 trials must please regulators and payers
Verona pharma’s CEO Jan Anders Karlsson told pharmaphorum that the company plans to take the drug into phase 3 trials, potentially for use in combination with existing therapies.
GlaxoSmithKline and Chiesi have recently begun marketing triple therapies for people in the late stages of COPD, which combine inhaled corticosteroids (ICS), a long-acting beta adrenoceptor agonist (LABA) and long acting muscarinic antagonist (LAMA) in one device.
