Summary
This is a prospective, open-label, multicenter, safety, comparative study of IV administered Tc99m-tilmanocept and unfiltered Tc99m sulfur colloid in the detection of and assessment of three dimensional tessellation localization to the liver in subjects with and without moderate to severe nonalcoholic steatohepatitis (NASH) by planar and SPECT/CT imaging. This study is designed to evaluate the safety and tolerability of Tc99m-tilmanocept in subjects with NASH.

disease(s) for at least 4 weeks prior to the consent date.

5. The subject has not taken any antibiotics for at least 4 weeks prior to the
consent date.

NASH SUBJECTS:

4. The subject has biopsy-confirmed NASH within 12 months prior to enrollment. 5. The
subject has a NAFLD Activity Score (NAS) of ≥ 4, with a score of at least 1 for each
steatosis, lobular inflammation, and hepatocyte ballooning.

Exclusion Criteria:

- ALL SUBJECTS:

diagnosis of cancer other than basal cell carcinoma.

4. The subject has renal insufficiency as demonstrated by a GFR of < 60 mL/min.

5. The subject has a chronic or persistent infection or has any condition that
would, in the opinion of the examining physician, preclude their participation.

6. The subject has a known allergy to or has had an adverse reaction to dextran
exposure.

7. The subject has received an investigational product within 30 days prior to the
Tc 99m sulfur colloid administration.

8. The subject has received any radiopharmaceutical within 7 days prior to the
administration of Tc 99m sulfur colloid.

9. The subject is HIV positive.

10. The subject has a history of alcohol abuse or currently consumes alcohol in
excess of 3 drinks/day for men or 2 drinks/day for women.

11. The subject has hepatitis B or C.

aminotransferase [SGPT]) or AST (aspartate aminotransferase [SGOT]) greater than
two times the upper limit of normal (ULN).

13. The subject has been diagnosed with NASH, NAFLD, or other chronic liver disease.

14. The subject has been diagnosed with metabolic syndrome or Type I or II diabetes.

NASH SUBJECTS:

12. The subject has any chronic liver disease aside from NASH/NAFLD.

13. The subject has uncontrolled diabetes as indicated by an A1c >9% within the 3 months
prior to enrollment.
