NCT05922306

Brief Summary

Previous studies have shown that there are alterations in the number and affinity of interferon receptors during interferon therapy and that such alterations recover to varying degrees some time after the end of treatment. It can be conjectured that the rest period of pulsed therapy facilitates the recovery of type I interferon receptors and thus the next round of IFN therapy compared to a continuous regimen of interferon.

Outcome Measures

Primary Outcomes (2)

  • HBsAg negative conversion rate after 96 weeks of treatment

    After 96 weeks of treatment, 5 ml of blood will be drawn from the patient, serum will be extracted, and HBsAg values will be quantified by chemiluminescence assay; samples less than 0.5 ng/ml will be judged as negative.

    96 weeks

  • HBsAb conversion rate after 96 weeks of treatment

    After 96 weeks of treatment, 5 ml of blood will be drawn from the patient, serum will be extracted, and HBsAb values will be quantified by chemiluminescence; samples greater than 10 miu/ml 0.5 will be judged as positive.

    96 weeks

Study Arms (2)

Continuous Combination Therapy Cohort

ACTIVE COMPARATOR

Patients with primary CHB with HBsAg ≥ 1500 IU/ml and HBV-DNA \< 500 IU/ml and patients with CHB after treatment with NAs will be enrolled. After fully informed consent, pegylated interferon alpha-2b 180µg will be administered by subcutaneous injection once a week for up to 96 weeks.

Drug: PEGylated recombinant human interferon alpha-2b injection

Pulsed Combination Therapy Cohort

EXPERIMENTAL

Patients with primary CHB with HBsAg ≥ 1500 IU/ml and HBV-DNA \< 500 IU/ml and patients with CHB after treatment with NAs will be enrolled. After fully informed consent, pegylated interferon alpha-2b 180µg will be administered by subcutaneous injection once weekly for 8 weeks of treatment and discontinued for 4 weeks up to 96 weeks.

Drug: PEGylated recombinant human interferon alpha-2b injection

Interventions

Continuous combination therapy: pegylated interferon alpha-2b 180µg, subcutaneously once a week for 96 weeks, combined with NAs throughout the treatment period.

Also known as: Nucleotide analogues

  • History of severe psychiatric illness, especially depression. Major psychosis defined as major depressive disorder or psychosis, suicide attempts, hospitalisation for psychosis or incapacity for a period of time due to psychosis;
  • history of immune-mediated disease (e.g. inflammatory bowel disease, idiopathic thrombocytopenic purpura, lupus erythematosus, autoimmune haemolytic anaemia, scleroderma, severe psoriasis, rheumatoid arthritis) or abnormally elevated levels of autoimmune antibodies
  • Patients with severe combined diseases of the heart, lungs, kidneys, brain, blood and other vital organs, combined with other malignancies
  • History of severe epilepsy or current treatment with anti-epileptic drugs. Unstable control of diabetes mellitus, hypertension, thyroid disease, etc. Patients with a history of severe retinopathy or as indicated by other evidence of retinopathy;
  • History of any organ transplantation and existing functional grafts (except corneal or hair transplants);
  • Patients who are allergic to interferon and its drug components and who, in the judgment of the investigator, are unsuitable for interferon application
  • Patients who, in the opinion of the investigator, are not suitable for participation in this study.
