This study is a Phase 2a First-in-Human (FIH) clinical trial to assess the safety, tolerability, pharmacodynamics (PD), and efficacy of multiple ascending doses of CNP-104. The study consists of a 120 day primary study followed by a 20 month long-term safety and durability of response follow-up period.
A Phase 2a Double Blind, Placebo Controlled Study to Evaluate the Safety, Tolerability, Pharmacodynamics, and Efficacy of CNP-104 in Subjects Ages 18-75 With Primary Biliary Cholangitis Who Are Unresponsive to UDCA and/or OCA
Subjects ages 18-75 with primary biliary cholangitis will be screened up to 14 days prior to enrollment into the study. Screening will be completed to assess eligibility, obtain vital signs, collect laboratory samples and PD measurements, and to receive a FibroScan for liver fibrosis. Subjects will additionally complete an initial PBC-40 assessment and begin an Itch Diary, a questionnaire and scoring system to be completed by the patient every morning and evening through Day 120 and then monthly through end of study.
Subjects who meet all inclusion and no exclusion criteria after completing the screening visit will be enrolled in the study. Subjects will be randomized on Day 1 in a 1:1 ratio to receive either CNP-104 or Placebo (0.9% Sodium Chloride USP) by intravenous (IV) infusion. Subjects will be administered CNP-104 or Placebo on Day 1 and on Day 8.
Subjects will remain in the clinic on Day 1 and Day 8 from the time of admission (prior to administration of CNP-104 or Placebo) through the final procedure conducted 4 hours post-dose that same day unless an infusion reaction, or other adverse event, requires an extended duration of monitoring. Subjects will be discharged if safety parameters are acceptable to the investigator.
Seven days after the second administration of CNP-104 or Placebo, subjects must return to the clinic for collection of safety labs, PD measurements, and assessment of AEs and medication changes.
Subjects will continue to be followed for 2 years to assess safety, pharmacodynamics, and immunogenicity during the Post-Dosing period.

- Imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the absence of a non-ischemic cause
- Pathological findings of a healed or healing myocardial

Subjects who have used biologic agents including anti-cell and anti-cytokine therapies within 12 months prior to screening.
10. Subjects with a history of tuberculosis or positive PPD skin test. 11. Subjects who have received administration of any live vaccine (other than intranasal
Influenza) within 28 days or subunit vaccine within 14 days prior to screening or are planning to receive any vaccination before Day 90.
12. Subjects who have used systemic steroids within 3 months prior to screening. 13. Subjects with laboratory test results at screening or prior to study dosing that are
outside the normal limits and considered by the Investigator to be clinically significant.
Note: This criterion does not apply to liver function tests. Additionally, clinically significant laboratory test results at screening that are related to the condition (PBC) are acceptable as long as all inclusion and no other exclusion criteria are met.
14. Subjects with positive test results for hepatitis B surface antigen (HBsAg), hepatitis
C virus (HCV) antibody, or human immunodeficiency virus (HIV) antigen/antibody as determined at screening.
15. Subjects with a history of or currently active immune disorders other that PBC
(including autoimmune disease) unless the condition, after discussion with the Medical Monitor, has been deemed to be acceptable for the subject's participation in this study.
16. Subjects with a history of or current active diseases requiring immunosuppressive
drugs (including azathioprine, prednisone, prednisolone, budesonide, cyclosporine, tacrolimus, methotrexate, or mycophenolate mofetil) unless the condition, after discussion with the Medical Monitor, has been deemed to be acceptable for the subject's participation in this study.
17. Subjects with a clinical history of significant cardiovascular disease as determined
by the Investigator.
18. Subjects with a complication or medical history of malignancy within past 5 years
which, in the Investigator's opinion, makes the subject unsuitable for study participation.
