These include the association of serious adverse events and comorbidities associated with the emergence of biologic therapies as potential treatments for SS, the need for further research to investigate the etiology and genetics of SS, and improved, specific classification criteria that can be effectively used for clinical therapeutic trials. Serious adverse events and associated comorbidities associated with the emergence of biologic agents as potential treatments for SS are one factor driving the development of internationally accepted classification criteria to define the autoimmune disorder. Other factors include a need to better support etiologic and genetic research and therapeutic trials, and to support enrollment into clinical trials with clear, easily applied, and highly specific classification criteria [Shiboski SC et al. \u003Cem\u003EArthritis Care Res (Hoboken)\u003C\/em\u003E 2012].\u003C\/p\u003E\u003Cp id=\u0022p-3\u0022\u003EThe objectives of the Sj\u00f6gren\u0027s International Collaborative Clinical Alliance (SICCA), which has been funded since 2003 by the National Institute of Dental and Craniofacial Research, were to develop new classification criteria for SS; to better characterize the SS phenotype and genotype; and to establish an SS data and specimen repository to support future research, including genetic studies by investigators worldwide.\u003C\/p\u003E\u003Cp id=\u0022p-4\u0022\u003EUsing a consensus methodology derived from the nominal group technique among 20 experts and analyses involving 1362 participants with complete data on 10 individual tests, the SICCA scientists first developed preliminary classification criteria for SS. Then a series of validation analyses was performed, including a comparison with American-European Consensus Group criteria [Shiboski SC et al. \u003Cem\u003EArthritis Care Res (Hoboken)\u003C\/em\u003E 2012].\u003C\/p\u003E\u003Cp id=\u0022p-5\u0022\u003EStephen Shiboski, PhD, University of California, San Francisco, San Francisco, California, USA, explained that the diagnostic and classification criteria rely on well-established objective tests that are clearly associated with the systemic, oral, and ocular characteristics of the disease and include alternate tests only when diagnostically equivalent. To increase their credibility and maximize standardization when enrolling participants into clinical trials, he cited the need for endorsement by professional rheumatology organizations across the world [Shiboski SC et al. \u003Cem\u003EArthritis Care Res (Hoboken)\u003C\/em\u003E 2012].\u003C\/p\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-1\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003ENext Step: Guideline Development\u003C\/h2\u003E\n         \u003Cp id=\u0022p-6\u0022\u003EAccording to Steven E.
