In page Ciclosporin:

"

Ciclosporin is highly metabolized in humans and animals after ingestion. The metabolites, which include cyclosporin B, C, D, E, H, and L,[2] have less than 10% of ciclosporin's immunosuppressant activity and are associated with higher kidney toxicity.[3] Individual ciclosporin metabolites have been isolated and characterized but do not appear to be extensively studied.
