A Study of TAK-007 in Adults With Refractory Lupus Nephritis (LN) or Refractory Systemic Sclerosis (SSc)

The main aim of the trial is to learn how well adults with refractory lupus nephritis (LN) or refractory systemic sclerosis (SSc) tolerate TAK-007 and to check for side effects (adverse events). Other aims are to learn how effective treatment with TAK-007 is in adults with refractory LN or refractory SSc, what effects TAK-007 has on the human body, and whether participants will produce antibodies against TAK-007.
