简要总结

A multi-centre, randomized, non-inferiority trial in patients with irH, randomized to receive either close surveillance with corticosteroid rescue therapy or early high dose corticosteroids.

详细描述

Immune checkpoint inhibitors (ICIs) are a class of immunotherapy drugs that helps signal to the immune system to seek out and destroy cancer. However despite showing clinical benefit over traditional chemotherapy, ICIs can lead to certain toxicities called immune-related adverse events (irAEs).

One of these irAEs is immunotherapy related hepatitis (irH) and is an important and less common toxicity of ICI therapy that could develop into a rare but serious complication of sudden liver failure. The management of irH includes high-dose steroids and use of steroids is not without significant side effects, especially when used for longer term.

Given the potential consequences of high dose long-term corticosteroids along with the implications of permanently discontinuing therapy, it is necessary to better understand the pathophysiology associated with irH and clarify the role of steroids in managing this patient population. It is especially important to determine which patients require intervention with steroids and other immunosuppression versus those that could simply be monitored for spontaneous resolution.

The results of this trial will identify predictors of irH resolution and inform judicious use of corticosteroids and immunosuppressive therapy for this at-risk population.

This study has been designed as a randomized, phase II non-inferiority study to investigate the efficacy of an active surveillance with steroid rescue strategy compared to early initiation of corticosteroids in the setting of irH secondary to ICIs. The study treatment period is 12 weeks with twice weekly liver enzyme function assessments. Once irH has improved to by one CTCAE grade (i.e. grade 3 to 2, or grade 2 to 1), this can be decreased to weekly assessment. For patients who continue to have asymptomatic liver enzyme elevation of grade 2 or higher, maintaining a surveillance strategy beyond this point is not appropriate, as investigators may wish to adjust therapy, especially if this is resulting in delay in resuming ICI. In this setting, weekly liver enzyme assessment will continue. The frequency of liver enzyme monitoring can be increased at the discretion of the investigator or hepatologist.

入选标准

  • Patients must be 18 years of age, or older on the day of signing informed consent.
  • Patients must be capable of providing consent to enrolment and treatment.
  • Patients with a performance status of ECOG 0-2 will be eligible for enrolment.
  • Patients with histologically confirmed cancer receiving anti-PD1 or anti-PDL1 monoclonal antibody ICI therapy, either alone or in combination with anti-CTLA-4 monoclonal antibody ICI therapy who develop CTCAEv5.0 grade 2 or grade 3 hepatitis that has developed on, or after, ICI therapy and is felt to be treatment related (irH). Patients must be enrolled on trial within 10 days of diagnosis of grade 2 or grade 3 hepatotoxicity.
  • Absence of any condition hampering compliance with the study protocol and follow- up schedule; those conditions should be discussed with the patient before registration in the trial.
  • Assessment by the Roussel Uclaf Causality Assessment Method (RUCAM) ≥6 showing probable relationship between ICI and liver injury (appendix)

排除标准

  • History underlying liver disease, including, but not limited to: hepatitis B, C, autoimmune hepatitis, primary biliary sclerosis, hemochromatosis, primary sclerosis cholangitis, portal vein thrombosis, Budd Chiari syndrome, alcohol induced hepatitis, suspected drug-induced liver injury from other cause (e.g. acetaminophen, antibiotics, statins, methyldopa, non-prescription herbs, see NIH LiverTox website https://livertox.nih.gov for comprehensive list).
  • If undertaken, liver biopsy supporting a cause of liver dysfunction other than irH
  • Patients with an indication for systemic immunosuppressive medications or corticosteroids. Patients with CTCAEv5.0 grade ≥2 irAE's other than irH (ie. colitis, pneumonitis, rash, etc.) are not eligible for trial, with the exception of endocrinopathies that are being treated with hormone replacement alone and not systemic immunosuppressive medications or corticosteroids.
  • Abnormal International Normalization Ratio (INR) at baseline (≥1.5) and bilirubin ≥60, ALT of ≥10X.
  • Previous use of targeted therapies for treatment of malignancy (e.g. BRAF, MEK, EGFR, and VEGF inhibitors) or current treatment with chemotherapy
  • Present use of warfarin.
  • Diagnosis of immunodeficiency.
  • Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication).
  • Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (CTCAEv5.0 Grade ≥ 3).
  • Other severe acute or chronic medical conditions including inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.

研究组 & 干预措施

Active surveillance with rescue corticosteroids

干预措施: Active Surveillance (Other)

2- Early initiation of steroid (Standard)

Active Comparator

Early intervention with high-dose steroids

干预措施: Early initiation (Other)

结局指标

主要结局

Resolution of biochemical abnormalities in grade 2 and grade 3 irH at 12 weeks.

时间窗: 12 weeks

The primary objective of this clinical trial is to determine if active surveillance with steroid salvage is a non-inferior strategy in grade 2 and grade 3 irH in patients without evidence of liver dysfunction. Resolution will be defined as improved in irH to grade ≤1. This was chosen as a clinically significant endpoint as it is often used by oncologists to determine if patients may resume ICI therapy. Assessment and grading will be completed by the investigator according to CTCAEv5.0

次要结局

  • Safety of Steroid Sparing Strategy(1 year)
  • Total steroid usage(1 year)
  • Development of immune related adverse events (irAE's) other than irH.(1 year)
  • Re-initiation of immune checkpoint inhibitor therapy.(1 year)
  • The time elapsed between randomization and tumor progression (radiographically or clinically) or death from any cause(1 year)
