Biodistribution & persistence
Wide tissue distribution; highest in GI tract and liver; brain and spinal cord above blood levels
“In albino rats, radioactivity was widely distributed into most tissues and was maximal at 1-4 hours post-dose. The highest exposures were found in GI tract and liver but was also observed in the brain and spinal cord at higher levels than blood at 1-4 hours post-dose.”

Modality-specific risk
Cardiovascular and lung toxicity, and serious teratogenic effects
“The pivotal nonclinical studies of ponesimod were adequately conducted and identified target organs for toxicity (including cardiovascular and lung) and serious developmental (teratogenic) effects.”
