Positive topline results with GLPG1972 in osteoarthritis patients

MECHELEN, Belgium I January 7, 2018 I Galapagos NV (Euronext & NASDAQ: GLPG) reports positive preliminary topline results with a Phase 1b study in osteoarthritis (OA) patients in the United States.

Galapagos evaluated GLPG1972 in a randomized, placebo-controlled, double-blind Phase 1b study in 30 patients aged 50 to 75 years with diagnosis of knee and/or hip osteoarthritis, in the United States. Patients were given one of three doses of GLPG1972 or placebo for a total of 4 weeks, with a 3 week follow-up period. Primary objectives were to evaluate safety, tolerability, and pharmacokinetics of GLPG1972 in patients. A secondary objective was to measure the reduction of ARGS neoepitope, an important cartilage breakdown biomarker.

The mechanism of action of GLPG1972, which targets a cartilage degrading enzyme called ADAMTS-5, was confirmed in two animal models. An earlier Phase 1 study in healthy volunteers met all its safety and pharmacokinetic targets and also demonstrated that GLPG1972 reduced the blood level of ARGS neoepitope by up to more than 50% within two weeks.

In this Phase 1b study in patients, GLPG1972 was well tolerated. There was one treatment discontinuation with reversible abnormal liver function test on Day 15 in the highest dose cohort. The pharmacokinetics of GLPG1972 in a population of elderly individuals with OA were similar to those in healthy volunteers, potentially supporting once-daily oral treatment.

Patients on treatment achieved a dose-dependent, reduction of ARGS neoepitope versus placebo:

"We are pleased that this study extends our findings of more than 50% reduction in cartilage breakdown biomarker in healthy subjects to patients with osteoarthritis in a sustained way over a 4-week period," said Dr. Piet Wigerinck, Chief Scientific Officer of Galapagos. "We are working diligently with our collaboration partner Servier to prepare a global Phase 2 program expected to start later this year, and to further develop GLPG1972 as a potentially disease-modifying molecule for OA."

OA is a highly prevalent and disabling pathology. So far, no treatment is available to counteract disease progression, patients being left with only symptomatic treatments. As a result, OA represents an important unmet medical need.  Since 2010, Servier[1] and Galapagos joined their expertise to tackle this problem, leading to the development of GLPG1972, a first-in-class and potentially disease-modifying investigational molecule. Galapagos has full US commercial rights to GLPG1972. Under the terms of the agreement, Galapagos is also eligible to receive development, regulatory and other milestone payments plus royalties upon commercialization outside the US.

GLPG1972 is an investigational candidate drug and its safety and efficacy have not yet been established.
