Figure 2: Potential indications for TYK2-targeted molecules, page 102 7. We note your response to prior comment 19, including that the figures represent the market for IBD and UC in patients at all severity levels. Please tell us why it would not be more appropriate to disclose the addressable market for moderate-to severe IBD and UC, which appears to be the target market that you address. Please also clarify whether the third column in Figure 2 represents global revenue associated with treatments for moderate-to-severe disease. Additionally, please provide the basis for your statements that that all of your product candidates target multi-billion-dollar commercial markets. In this regard, it appears that SLE only represents a one billion dollar market and there is no global revenue data provided for Lupus Nephritis.
