Galapagos advances CF clinical development

  • Initiation of Phase 1 study with corrector GLPG2222, earning Galapagos a $10 million milestone payment from AbbVie
  • Expansion of CF portfolio with three novel candidate drugs, with aim to create the most effective combo

Mechelen, Belgium; 19 January 2016: Galapagos NV (Euronext & NASDAQ: GLPG) provides an update on progress made in the cystic fibrosis (CF) programs. Galapagos and AbbVie (NYSE: ABBV) aim to develop a triple CFTR combination therapy to address 90% of patients with CF. In order to bring a more effective therapy to patients, the companies plan to develop multiple candidates and backups for each of the three components (1st generation correctors, next generation correctors, and potentiators) with the goal of identifying a potential triple combination. In addition to our potentiator and corrector that are being tested in the clinic, a total of four additional compounds have the potential to reach clinical development in the CF program this year.

Triple combinations of CF compounds in the portfolio have consistently shown restoration of healthy activity levels in in vitro assays with human bronchial epithelial (HBE) cells of patients with the F508del mutation. These combinations result in chloride transport with an increase over Orkambi1 in HBE cells with the homozygous F508del mutation.

First generation corrector series
Dosing to humans of GLPG2222, the first 1st generation corrector in Galapagos’ portfolio, started earlier this month. This achievement earns Galapagos a $10 million milestone payment in connection with the global collaboration agreement with AbbVie. Galapagos is conducting a randomized, double-blind, placebo-controlled study over a range of doses of GLPG2222 in healthy volunteers in Belgium and expects topline results in Q2 2016. Galapagos further announces the selection of preclinical candidate GLPG2851, an additional 1st generation corrector, aiming to initiate Phase 1 with this compound by the end of 2016.

Next-generation corrector series
Galapagos announced selection of the first next-generation corrector GLPG2665 in October 2015, expected to enter Phase 1 by mid-2016. Today Galapagos announces selection of an additional next-generation corrector GLPG2737, expected to enter Phase 1 in healthy volunteers by Q4 2016. Galapagos and AbbVie are also developing an alternative series of next-generation correctors with different activity and expect to nominate candidates and additional compounds from that series later in 2016.

Potentiator series
Galapagos has made regulatory filings for exploratoryPhase 2 studies in CF patients for potentiator GLPG1837, and has received the first approvals to start from a number of countries. This early exploratory Phase 2 program with GLPG1837 will be conducted in Europe in G551D and S1251N mutation types. Additional potentiator GLPG2451 has entered preclinical development and is expected to move into Phase 1 trials in Q2 2016.

“Galapagos and AbbVie continue to make strong progress with our cystic fibrosis portfolio,” said Onno van de Stolpe, CEO of Galapagos. “The CF franchise has really expanded into a full-sized portfolio. The resulting breadth, depth, and preclinical promise of this collection of modulators brings us again closer to our aim of bringing a superior triple combination therapy to CF patients.”

1 Orkambi® is a prescription medicine sold by Vertex Pharmaceuticals, used for the treatment of cystic fibrosis (CF) in patients age 12 years and older who have two copies of the F508del mutation (F508del/F508del) in their CFTR gene.

About the Galapagos – AbbVie collaboration in cystic fibrosis
In September 2013 Galapagos and AbbVie, a global biopharmaceutical company, entered into a global collaboration agreement focused on the discovery and worldwide development and commercialization of potentiator and corrector molecules for the treatment of CF. Under the terms of the agreement, AbbVie made an upfront payment of $45 million to Galapagos. Upon successful completion by Galapagos of clinical development through to completion of Phase 2, AbbVie will be responsible for Phase 3, with financial contribution by Galapagos. Galapagos has earned $20 million in milestone payments to date and is eligible to receive up to $340 million in total additional payments for developmental and regulatory milestones, sales milestones upon the achievement of minimum annual net sales thresholds and additional tiered royalty payments on net sales, ranging from mid-teens to 20%.

About cystic fibrosis (CF)
CF is a rare, life-threatening, genetic disease that affects approximately 80,000 patients worldwide and approximately 30,000 patients in the United States. CF is a chronic disease that affects the lungs and digestive system. CF patients, with significantly impaired quality of life, have an average lifespan approximately 50% shorter than the population average, with the median age of death at 40. There currently is no cure for CF. CF patients require lifelong treatment with multiple daily medications, frequent hospitalizations and ultimately lung transplant, which is life-extending but not curative. CF is caused by a mutation in the gene for the CFTR protein, which results in abnormal transport of chloride across cell membranes. Transport of chloride is required for effective hydration of epithelial surfaces in many organs of the body. Normal CFTR channel moves chloride ions to outside of the cell. Mutant CFTR channel does not move chloride ions, causing sticky mucous to build up on the outside of the cell. CFTR dysfunction results in dehydration of dependent epithelial surfaces, leading to damage of the affected tissues and subsequent disease, such as lung disease, malabsorption in the intestinal tract and pancreatic insufficiency.
