Here we present data from the Observational Study of Psoriatic Arthritis Treated with Leflunomide (OSPAL), a postauthorization study that assessed the effectiveness and safety of leflunomide in adult patients with active PsA. Data were collected in Germany, the Czech Republic, and in Slovenia.
What is 'Research And Development - R&D' Research and development (R&D) refers to the investigative activities a business conducts to improve existing products and procedures or to lead to the development of new products and procedures. Consumer goods companies across all sectors and industries utilize R&D to improve on product lines, and corporations experience growth through these improvements and through the development of new goods and services.
R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation of new products.
