简要总结
This clinical trial is to clarify and investigate the patterns of immune-related hepatitis and the optimal treatment choice for patients who are steroid-dependent. The project aims to prospectively characterize the various histopathological, biochemical, and phenotypical liver injury patterns induced by immune checkpoint inhibitors and the treatment responses to corticosteroids. Furthermore, the effect of adding a second-line immunosuppressive drug, either MMF in steroid-refractory or steroid-dependent cases will be explored and compared.
详细描述
The number of patients treated with immune checkpoint inhibitors (ICI) is expanding worldwide due to an increasing number of indications, including additional types of cancer, combination of ICI with other antineoplastic therapies and have recently moved into the adjuvant setting. According to clinical trial material, almost all patients in ICI treatment will eventually develop any grade of an adverse event, here, estimated in up to 90 percent of treated patients. Around 10-30 percent of ICI-treated patients will show signs of liver injury related to ICI treatment and will be diagnosed with immune-related hepatitis. The treatment hereof should include observation and medium-dose steroids in low-grade asymptomatic patients (grade ≤ 2 ir-hepatitis) and high-dose steroids in higher grades according to the current European and American guidelines. However, up to 25 percent of patients with ir-hepatitis may not respond properly to steroids due to primary resistance or relapse during tapering. These patients should be offered a second-line immunosuppressive treatment. The present recommendation for patients with steroid-dependent ir-hepatitis is based on the case series and includes immunosuppressive treatment with mycophenolate mofetil (MMF). To date, no evidence exists for which second-line treatment to choose.
However, in the clinic, the initiation of MMF may be delayed, meanwhile, patients are typically treated with an increased dose of steroids. In some cases, an increased dose of steroids with prolonged tapering can be sufficient. We want to explore if increased doses of steroids or adding MMF is the best strategy for relapse of hepatitis.
In addition, patients with signs of biliary or mixed liver injury may benefit from adding ursodeoxycholic acid (UDCA).

研究组 & 干预措施
Cohort A: Steroids and MMF in grade 3-4 ir-hepatitis
Patients with ≥ 3 grade ir-hepatitis will be treated with high-dose steroids 2 mg/kg/day intravenously. A diagnostic liver biopsy will be taken. Patients with mixed or cholestatic liver injury patterns will be added UDCA. Treatment evaluation will be performed after 72 hours, patients in UDCA will be evaluated will be on day 7. Patients with sufficient steroid response defined as ≥ 20% reduction in ALT, AST, ALP or bilirubin at day 4 or day 7 will undergo steroid tapering with a transition to peroral steroids. Patients with initial insufficient treatment response, defined as less than < 20% reduction in ALT, AST, ALP, or bilirubin, are considered as having a steroid-refractory condition and will be added MMF. In case of no response or increase of ALT, AST, ALP, or bilirubin during treatment with steroids plus MMF a third-line treatment may be introduced according to the individual treating hepatologist.
