Mechelen, Belgium and Planegg/Munich, Germany; 13 September 2018; 22.01 CET; Galapagos NV (Euronext & NASDAQ: GLPG) and MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX; NASDAQ: MOR) announced today the initiation of a Phase 1 bridging study testing a subcutaneous formulation of MOR106, an investigational antibody directed against IL-17C.

This bridging study is a parallel-design Phase 1 clinical trial conducted in two parts. Part 1 is a single center, randomized, open-label study in healthy volunteers who will be treated with different single dose levels of MOR106 administered subcutaneously or intravenously. Part 2 is a multiple center, randomized, placebo-controlled, multiple dose study in patients with moderate to severe atopic dermatitis who will be treated subcutaneously for 12 weeks.

Safety and tolerability, pharmacokinetics (PK) and occurrence of anti-drug-antibodies after administration of MOR106 will be assessed as endpoints. In addition, the efficacy of MOR106 will be explored in subjects with moderate to severe atopic dermatitis.

"The start of the bridging study together with Galapagos with a subcutaneous formulation of MOR106 is an important milestone in its clinical development," commented Dr. Malte Peters, Chief Development Officer of MorphoSys AG. "This route of subcutaneous administration is widely used for the treatment of chronic skin diseases, and we intend to evaluate it in this study with the goal of providing support for the further clinical development of MOR106." 

"This study represents the next important step in our strategy to progress MOR106 rapidly in the clinic and is expected to provide additional insights into patient response, while we await the results of our ongoing IGUANA Phase 2 trial with MOR106 in atopic dermatitis patients," said Dr. Walid Abi-Saab, Chief Medical Officer of Galapagos.

MOR106 was generated using MorphoSys's Ylanthia antibody platform and is based on a target discovered by Galapagos. IL-17C is a cytokine expressed preferentially in the skin and which has been implicated in dermal inflammation and shown to be distinct from other members of the IL-17 cytokine family. MOR106 is the first publicly known human monoclonal antibody directed against IL-17C in clinical development worldwide. MOR106 is an investigational drug and its safety and efficacy have not yet been established. Novartis Pharma AG owns the worldwide, exclusive license for the development and commercialization of MOR106 under an agreement with MorphoSys and Galapagos which became effective on September 10, 2018.

Galapagos forward-looking statements
This release may contain forward-looking statements, including, among other things, statements regarding the mechanism of action and profile of, and timing and results of clinical trials with, and potential commercialization of, MOR106, statements regarding potential future payments to be made to Galapagos under a licensing agreement for MOR106. 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 that expectations regarding the further development of MOR106 in moderate-to-severe atopic dermatitis, including the intended targeting of IL-17C, and potential additional indications, potential future payments to be made to Galapagos under a licensing agreement for MOR106, as well as Galapagos' expectations regarding the MOR106 development program may be incorrect, the inherent uncertainties associated with competitive developments, clinical trial and product development activities and regulatory approval requirements (including that data from the ongoing clinical research programs may not support registration or further development of MOR106 due to safety, efficacy or other reasons), Galapagos' reliance on collaborations with third parties (including its collaboration partners for MOR106, MorphoSys and Novartis), and estimating the commercial potential of Galapagos' product candidates. A further list and description of these risks, uncertainties and other risks can be found in Galapagos' Securities and Exchange Commission (SEC) filings and reports, including in Galapagos' most recent annual report on Form 20-F filed with the SEC and other filings and reports filed by Galapagos with the SEC. Given these uncertainties, the reader is advised not to place any undue reliance on such forward-looking statements. These forward-looking statements speak only as of the date of publication of this document. Galapagos expressly disclaims any obligation to update any such forward-looking statements in this document to reflect any change in its expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements, unless specifically required by law or regulation.
