- Participants between 5 and 17 years of age inclusive, at the time of informed consent
- Chinese pediatric participants with SLE, who have completed 48 weeks treatment in study 213560 and who, in the opinion of the investigator, may benefit from treatment with GSK1550188.
- Participants who have developed clinical evidence of significant, unstable or uncontrolled, acute or chronic diseases not due to SLE (i.e., cardiovascular, pulmonary, hematologic, gastrointestinal, hepatic, renal, neurological, malignancy or infectious diseases), or experienced an Adverse events (AE) in 213560 study that could, in the opinion of the principal investigator, put the participant at undue risk.
- Have developed any other medical diseases (e.g., cardiopulmonary), laboratory abnormalities, or conditions that, in the opinion of the principal investigator, makes the participant unsuitable for the study.

- Participant signs and dates a written age-appropriate assent form (in accordance with applicable regulations) and the parent or legal guardian (or emancipated minor) that has the ability to understand the requirements of the study, provides written informed consent (including consent for the use and disclosure of research-related health information) that the participant will comply with the study protocol procedures (including required study visits).
Exclusion criteria:
- Participants who have developed clinical evidence of significant, unstable or uncontrolled, acute or chronic diseases not due to SLE (i.e., cardiovascular, pulmonary, hematologic, gastrointestinal, hepatic, renal, neurological, malignancy or infectious diseases), or experienced an Adverse events (AE) in 213560 study that could, in the opinion of the principal investigator, put the participant at undue risk.
- Have developed any other medical diseases (e.g., cardiopulmonary), laboratory abnormalities, or conditions that, in the opinion of the principal investigator, makes the participant unsuitable for the study.

If present, any abnormalities in the alanine transaminase (ALT) and/or aspartate aminotransferase (AST) must be <= Grade 2. d) Stable Grade 3 neutropenia; or stable Grade 3 lymphopenia; or stable Grade 3 leukopenia, due to SLE.
