Mechelen, Belgium; 16 March 2016 - Galapagos NV (Euronext & NASDAQ: GLPG) announced today the first dosing in CF patients with the G551D mutation in the SAPHIRA 1 study.
GLPG1837 is a candidate CFTR potentiator drug in clinical development for the treatment of Class III mutations in cystic fibrosis (CF). The full SAPHIRA Phase 2 program will explore the safety, tolerability and efficacy of GLP1837 in CF patients with a G551D (SAPHIRA 1) or S1251N (SAPHIRA 2) Class III mutation. First dosing of the exploratory study SAPHIRA 1 took place this week in Australia.
First dosing in patients with the S1251N mutation in the SAPHIRA 2 study has started last month. Topline results from both SAPHIRA 1 and 2 Phase 2 studies are expected in H2 2016.
"We are very excited about this rapid recruitment for the SAPHIRA program," said Onno van de Stolpe, CEO of Galapagos. "We look forward to seeing to what extent our promising in vitro data translates into clinical results and are determined to deliver our novel CF compounds to patients as soon as possible. We aim to start and report a number of clinical studies with additional compounds in the CF portfolio throughout 2016."
About the SAPHIRA Phase 2 program
SAPHIRA 1, an open-label study of three doses of GLPG1837 in at least 12 patients with the G551D mutation, was first dosed in patients this week. SAPHIRA 2, an open-label study of two doses of GLPG1837 in at least six CF patients with the S1251N mutation, was first dosed in February 2016. The SAPHIRA Phase 2 program will explore the safety, tolerability, efficacy, and medicine-like properties of GLPG1837 in patients in six EU countries and Australia. Primary objectives are to evaluate the safety and tolerability; secondary objectives are to assess changes in sweat chloride from baseline as the biomarker of cystic fibrosis transmembrane conductance regulator (CFTR) ion channel function and to explore the changes in pulmonary function (forced expiratory volume in 1 second [FEV1]) from baseline. Both studies will include subjects treated with Kalydeco«1 as well as those who are na´ve to this drug. In each study, different doses of GLPG1837 tablets will be administered twice daily for a total duration of four weeks. Both SAPHIRA studies are recruiting on track with plan.
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 in a potential triple combination therapy 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 received an additional $20 million in payments from AbbVie 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.
Galapagos (Euronext & NASDAQ: GLPG) is a clinical-stage biotechnology company specialized in the discovery and development of small molecule medicines with novel modes of action. Our pipeline comprises three Phase 2, three Phase 1, five pre-clinical, and 20 discovery studies in cystic fibrosis, inflammation, fibrosis, osteoarthritis and other indications. We have discovered and developed filgotinib: in collaboration with Gilead we aim to bring this JAK1-selective inhibitor for inflammatory indications to patients all over the world. Galapagos is focused on the development and commercialization of novel medicines that will improve people's lives. The Galapagos group, including fee-for-service subsidiary Fidelta, has approximately 440 employees, operating from its Mechelen, Belgium headquarters and facilities in The Netherlands, France, and Croatia.

This release may contain forward-looking statements, including statements regarding the anticipated timing of the SAPHIRA studies, the further recruitment of patients for such clinical studies and the potential activity and clinical utility of potentiator GLPG1837 for cystic fibrosis. Galapagos cautions the reader that forward-looking statements are not guarantees of future performance. Forward-looking statements involve known and unknown risks, uncertainties and other factors which might cause the actual results, financial condition and liquidity, performance or achievements of Galapagos, or industry results, to be materially different from any historic or future results, financial conditions and liquidity, performance or achievements expressed or implied by such forward-looking statements. In addition, even if Galapagos' results, performance, financial condition and liquidity, and the development of the industry in which it operates are consistent with such forward-looking statements, they may not be predictive of results or developments in future periods. Among the factors that may result in differences are the inherent uncertainties associated with competitive developments, clinical trial and product development activities and regulatory approval requirements (including that data from Galapagos' ongoing clinical research programs in cystic fibrosis may not support registration or further development of GLPG1837 to safety, efficacy or other reasons), Galapagos' reliance on collaborations with third parties (including the performance by AbbVie under the Galapagos-AbbVie Collaboration Agreement), and estimating the commercial potential of our product candidates. A further list and description of these risks, uncertainties and other risks can be found in the company's Securities and Exchange Commission filing and reports, including in the company's prospectus filed with the Securities and Exchange Commission on May 14, 2015 and subsequent filings and reports filed by the company with the Securities and Exchange Commission.
