简要总结
A double-blind placebo controlled randomized Phase 2 study to determine if JKB-122 compared with placebo resolves NASH on liver biopsy and improves fibrosis
详细描述
This is a Phase 2 study in which JKB-122 is given once daily for 52 weeks to subjects with Nonalcoholic steatohepatitis (NASH) with Fibrosis who have biopsy reading more than NAS 4 with a fibrosis reading more than 1 and no cirrhosis. Subjects will be at least 18 years of age, either male or female.

- •Stable use of insulin sensitizing agents (PPARs, SGLT2 inhibitors, or GLP-1 agonists for 6 months prior to screening liver biopsy).
- •Is capable of understanding and signing the informed consent document. If subject is unable to sign the informed consent form, then the subject's legal representative or guardian may provide written consent per local regulations.
- •Agrees to comply with protocol requirements.

- •Has a known or suspected central nervous system disorder that may predispose to seizures or lower the seizure threshold.
- •Has unstable and uncontrollable hypertension (>180/110 mmHg).
- •Has received other therapies for NAFLD in the last 4 weeks prior to the screening visit (Day -7).
- •Requires concomitant use of or treatment with opioids or other excluded drugs such as hepatotoxic medications.
- •Has received other investigational agents within 30 days prior to the screening visit (Day -7).
- •Has either autoimmune or genetic liver disease.

结局指标
主要结局
To evaluate the effect of JKB-122 compared to placebo to achieve NASH resolution on liver histology in non-cirrhotic NASH patients with stage 2 or 3 fibrosis
时间窗: 52 weeks
Assessment will be based on the proportion of JKB-122 15 mg or 35 mg treated patients relative to placebo achieving NASH resolution with at least a 2 point reduction in NAS and no worsening of fibrosis
To evaluate the effect of JKB-122 compared to placebo to achieve a ≥ 1 stage fibrosis improvement on liver histology in non-cirrhotic NASH patients with stage 2 or 3 fibrosis
时间窗: 52 weeks
Assessment will be based on the proportion of JKB-122 15 mg or 35 mg treated patients relative to placebo achieving at least a 1 stage improvement in fibrosis (NASH Clinical Research Network system) by liver biopsy with no worsening of NAS.
次要结局
- Evaluate the changes of hepatic fat content(52 weeks)
- Evaluate the changes of fibrosis score(52 weeks)
