AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with long-term hepatitis B whose virus is already held down by nucleoside or nucleotide analogue pills and who are HBeAg negative.
- Age
- 18 years or older
- Sex
- All sexes can join.

- Chronic hepatitis B, with HBV infection documented for at least 6 months before screening. Virus level (HBV DNA) must be below the lowest measurable level on treatment.
- Earlier treatment
- Must have taken a commercially available nucleoside or nucleotide analogue (NA) alone for at least 24 weeks before randomization. The dose must be unchanged for at least 4 weeks before randomization.
- Biomarker or test result
- HBeAg negative at screening. HBV DNA below the lower limit of quantitation.
Main reasons for not taking part
- History of cirrhosis, liver decompensation, or suspected or confirmed liver cancer

- Original description
This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and immunogenicity of HRS-5635 injection as compared to the placebo arm in nucleos(t)ide analogue-suppressed HBeAg-negative patients with chronic hepatitis B. The total duration of the study, including screening (up to 4 weeks), the double-blind treatment stage (60 weeks)，NAs-only treatment stage（12 weeks） and the off-treatment follow-up (24 weeks), is up to approximately 100 weeks at maximum for each participant.Read full original descriptionShow less
A Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-designed Phase III Clinical Study to Evaluate the Efficacy and Safety of HRS-5635 Injection in Nucleos(t)Ide Analogue-suppressed HBeAg-negative Patients With Chronic Hepatitis B
This study is intended to confirm the efficacy, safety, pharmacokinetic (PK) profile, and immunogenicity of HRS-5635 injection as compared to the placebo arm in nucleos(t)ide analogue-suppressed HBeAg-negative patients with chronic hepatitis B. The total duration of the study, including screening (up to 4 weeks), the double-blind treatment stage (60 weeks)，NAs-only treatment stage（12 weeks） and the off-treatment follow-up (24 weeks), is up to approximately 100 weeks at maximum for each participant.
Inclusion: Chronic hepatitis B defined as HBV infection documented for at least 6 months prior to screening; Virologically suppressed on nucleoside or nucleotide analogues treatment with HBV DNA below the lower limit of quantitation; HBeAg negative at screening; On commercially available NAs monotherapy for at least 24 weeks before randomization, and the dosing regimen remained unchanged for at least 4 weeks before randomization; Need to take effective contraceptive measures；; Volunteer to sign an informed consent.
Exclusion: Malignant tumors were diagnosed within 5 years prior to randomization；; Major trauma or major surgery within the 12 weeks prior to randomization, or surgical plans or other treatment during the study period which the investigators determined may influence the evaluation of the study results; History of drug use, alcohol or drug abuse in the 12 months prior to randomization; Participated in clinical study of other drugs (received experimental drugs); History of cirrhosis or clinical evidence of hepatic decompensation, confirmed or suspected liver cancer, with other liver diseases other than chronic hepatitis B that may affect the evaluation of the study; With autoimmune disease; History of solid organ transplantation or hematopoietic stem cell transplantation; Clinically significant and unstable or uncontrolled severe cardiovascular and cerebrovascular diseases; Allergic to a drug ingredient or component; Laboratory tests during the screening period were obviously abnormal; Prolonged ECG QTcF or other clinically significant abnormal results that may pose a significant safety risk to the subject during the screening period; Pregnant or nursing women; Other reasons for ineligibility as judged by the investigators.
