Researchers want to see if 4 drugs given alone or combined affect MS biomarkers. They want to see if a change in biomarker levels can predict which drugs a person with MS might respond to.

Summary: The purpose of this study is to evaluate efficacy of pioglitazone (PIO) versus empagliflozin (EMPA) to improve glycemic control in people with Chronic Pancreatitis (CP) or Recurrent Acute Pancreatitis (RAP) associated with Diabetes Mellitus (DM). To evaluate mixed meal response in PIO versus EMPA group to better understand physiology of both therapies in CP-DM.

Summary: The purpose of the study is to assess the effect of AZD5004 on the pharmacokinetics (PK) of mitiglinide and pioglitazone in healthy participants.
