Galapagos announces design for PINTA Phase 2 trial with GLPG1205 in IPFMonday, July 9, 2018
PINTA is a randomized, double-blind, placebo-controlled trial investigating a 100 mg once-daily oral dose of GLPG1205. The drug candidate or placebo will be administered for 26 weeks in up to 60 IPF patients. Patients may remain on their local standard of care as background therapy. Primary objective of the trial is to assess the change from baseline in Forced Vital Capacity (FVC in mL) over 26 weeks compared to placebo.Secondary measures include safety, tolerability, pharmacokinetics and pharmacodynamics, time to major events, changes in functional exercise capacity, and quality of life. IPF diagnosis will be confirmed by central reading. Recruitment for PINTA is planned in 10 countries in Europe, North Africa, and the Middle East. First dosing of an IPF patient is expected in the second half of 2018.
GLPG1205 is a GPR84 inhibitor discovered by Galapagos and fully proprietary to Galapagos. GLPG1205 showed a reduction in signs and symptoms in IPF animal models and has shown favorable tolerability in healthy volunteers and ulcerative colitis patients in previous trials. Galapagos currently has three drug candidates with distinct mechanisms of action in its fully proprietary portfolio aimed at building an IPF franchise: GLPG1690 in the ISABELA Phase 3 program, GLPG1205 in PINTA Phase 2, and GLPG3499, currently in pre-clinical development.
"GLPG1205 has shown signs of good activity in relevant animal models, and GPR84 has already been validated as a mechanism in combination with nintedanib in IPF," added Dr. Piet Wigerinck, Chief Scientific Officer of Galapagos. "We have a well-designed trial with PINTA for '1205 that we anticipate will give us new insights into the potential value of GPR84 inhibition as a mechanism to treat this highly fatal disease."
GLPG1205 is a small molecule selectively inhibiting GPR84, which is fully proprietary to Galapagos. Galapagos identified the GPR84 target using its proprietary target discovery platform and developed molecule GLPG1205 as an inhibitor of this target. GLPG1205 showed promising results in relevant pre-clinical models for IPF, and there is growing evidence in scientific literature and in clinical research that GPR84 plays a role in this disease. GLPG1205 successfully completed a Phase 1 trial in 2013, showing favorable findings relating to safety and tolerability, and target engagement in healthy volunteers. GLPG1205 showed good tolerability but no activity in ulcerative colitis patients in 2016. GLPG1205 is an investigational drug and its efficacy and safety have not been established.
IPF is a chronic, relentlessly progressive fibrotic disorder of the lungs that typically affects adults over the age of 40. There are approximately 200,000 patients with IPF in the U.S. and Europe. As such, IPF is considered a rare disease. The clinical prognosis of patients with IPF is poor as the median survival at diagnosis is 2 to 4 years. Currently, no medical therapies have been found to cure IPF. The medical treatment strategy aims to slow the disease progression and improve the quality of life.
Regulatory agencies have approved Esbriet® (pirfenidone) and Ofev® (nintedanib) for the treatment of IPF. Both pirfenidone and nintedanib have been shown to slow the rate of lung function decline in IPF and are gaining ground as the standard of care worldwide. These regulatory approvals represent a major breakthrough for IPF patients; yet neither drug improves lung function, and the disease continues to progress in the majority of patients despite treatment. Moreover, the adverse effects associated with these therapies include diarrhea, liver function test abnormalities with nintedanib, nausea and rash with pirfenidone. Therefore, there is still a large unmet medical need as IPF remains a major cause of morbidity and mortality.
