Risks related to product development, regulatory approval and commercialization

Product development, regulatory approval and commercialization
CSR report

We operate adequate standard operating procedures to secure the integrity and protection of our research and development activities and results, and the optimum allocation of our R&D budgets. The progress of the most important research and development programs is continuously monitored by our executive committee; they are discussed with the board of directors at least once per quarter, and board members with expertise in clinical and scientific matters occasionally attend meetings with our scientific staff to discuss and assess such programs. Nevertheless, due to our limited resources and access to capital, we must and have in the past decided to prioritize development of certain product candidates; these decisions may prove to have been wrong and may adversely affect our business.

We are heavily dependent on the success of our product candidate filgotinib. We are also dependent on the success of our other product candidates, such as GLPG1690, GLPG1205, GLPG1972, GLPG3312, GLPG3970, GLPG3667, GLPG0555 and GLPG2737. Filgotinib is currently under regulatory review for approval in the United States (priority review), Europe and Japan for the treatment of RA and is not approved anywhere globally. In addition, we are heavily investing in our early stage product pipeline, including our Toledo early stage compounds, and these drug candidates must undergo rigorous preclinical and clinical testing, the results of which are uncertain and could substantially delay or prevent the drug candidates from reaching the market.

We cannot give any assurance that any product candidate will successfully complete clinical trials or receive regulatory approval, which is necessary before it can be commercialized.

Our business and future success is substantially dependent on our ability to develop successfully, obtain regulatory approval for, and then successfully commercialize our product candidate filgotinib and our other product candidates. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA, the EMA or any other comparable regulatory authority, and we may never receive such regulatory approval for any of our product candidates. We cannot give any assurances that our clinical trials for filgotinib or our other product candidates will be completed in a timely manner, or at all. If filgotinib or any other product candidate is not approved and commercialized, we will not be able to generate any product revenues for that product candidate.

The regulatory approval processes of the FDA, the EMA, the MHLW and other comparable regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Results of earlier studies and trials as well as data from any interim analysis of ongoing clinical trials may not be predictive of future trial results and failure can occur at any time during the clinical trial process. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. If filgotinib or any other product candidate is found to be unsafe or has lack of efficacy, we will not be able to obtain regulatory approval for it and our business would be materially harmed.

The rates at which we complete our scientific studies and clinical trials depend on many factors, including, but not limited to, patient enrolment. Patient enrolment is a significant factor in the timing of clinical trials and is affected by many factors including competing clinical trials, clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available therapies and the relatively limited number of patients. Any of these occurrences may harm our clinical trials and by extension, our business, financial condition and prospects.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, the EMA, the MHLW or other comparable regulatory authorities. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

Based on preclinical findings, we expect that filgotinib, if approved, may have a labeling statement warning female patients of child-bearing age to take precautionary measures of birth control to protect against pregnancy, similar to warnings included with other frequently used medications in RA, such as methotrexate.

Filgotinib, if approved, may have a labeling statement warning for male patients. In preclinical studies, filgotinib induced adverse effects on the male reproductive system.  Adjacent to the filgotinib Phase 3 programs, we and Gilead are conducting dedicated male semen analysis studies in CD and UC patients (MANTA) and in RA, PsA, and AS patients (MANTA-RAy).

Even if filgotinib does receive regulatory approval or marketing authorization, the FDA or other regulatory authorities may impose dosing restrictions that differ from the approved dosing regimen in other jurisdictions.

Box warnings, labeling restrictions, dose limitations and similar restrictions on use could have a material adverse effect on our ability to commercialize filgotinib in those jurisdictions where such restrictions apply.

If we lose orphan product exclusivity for GLPG1690, or are not able to obtain such status for other or for future product candidates for which we seek this status, or if our competitors are able to obtain orphan product exclusivity before we do, we may not be able to obtain approval for our competing products for a significant period of time.

Our commercial success depends upon attaining significant market acceptance of our product candidates, if approved, among physicians, healthcare payers, patients and the medical community.

Coverage and reimbursement decisions by third-party payers may have an adverse effect on pricing and market acceptance. Legislative and regulatory activity may exert downward pressure on potential pricing and reimbursement for any of our product candidates, if approved, that could materially affect the opportunity to commercialize.
