Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part 1: Number of Participants With Treatment-emergent Adverse Event (TEAEs)	An adverse event (AE) was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAEs were defined as AEs occurring at or after the first dose date and time, through study termination, or existing prior to the time of and worsening after the time of the first dose of investigational product. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.	Up to 113 days
Primary	Part 2: Number of Participants With TEAEs	An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAEs were defined as AEs occurring at or after the first dose date and time, through study termination, or existing prior to the time of and worsening after the time of the first dose of investigational product. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.	Up to 162 days
Primary	Part 1: Maximum Observed Serum Concentration (Cmax) of Pegozafermin		Predose and up to 168 hours postdose on Day 29
Primary	Part 1: Area Under the Serum Concentration Versus Time Curve From Time Zero to the Last Measurable Concentration (AUClast) of Pegozafermin		Predose and up to 168 hours postdose on Day 29
Primary	Part 1: Time to Peak Serum Concentration (Tmax) of Pegozafermin		Predose and up to 168 hours postdose on Day 29
Primary	Part 1: Terminal Elimination Half-life (t1/2) of Pegozafermin		Predose and up to 168 hours postdose on Day 29
Primary	Part 2: Number of Participants With at Least a 2-point Improvement in NAFLD Activity Score (NAS) With at Least a 1-point Improvement in Ballooning or Lobular Inflammation, and no Worsening of Fibrosis	NAS was the sum of the scores of steatosis, inflammation, and ballooning. NAS score ranges from of 0 to 8, with higher scores indicating worse disease severity.; Worsening of fibrosis was defined as progression of fibrosis =1 stage in NASH Clinical Research Network (CRN) fibrosis score.; NASH CRN Fibrosis is staged on a 0-4 scale: 0 (none); 1 (perisinusoidal or periportal fibrosis); 2 (perisinusoidal and portal/periportal fibrosis); 3 (bridging fibrosis); 4 (cirrhosis).

Secondary	Part 2: Number of Participants With at Least an Improvement of Fibrosis =1 Stage Without Worsening of NASH	Fibrosis improvement was defined as =1-stage decrease in NASH CRN fibrosis score.; Worsening of NASH was defined as increase =1 point in NAS for ballooning or inflammation.; NASH CRN Fibrosis was staged on a 0-4 scale: 0 (none); 1 (perisinusoidal or periportal fibrosis); 2 (perisinusoidal and portal/periportal fibrosis); 3 (bridging fibrosis); 4 (cirrhosis).
