18 years to 65 years (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description

- Abstinence from heterosexual intercourse throughout the study, or
- Willingness to use highly effective contraception (double barrier method or barrier contraception in combination with hormonal or intrauterine contraceptive) throughout the study and for 3 months after the last dose of the study medication for participants discontinued during the treatment period.
- Individuals must agree to use a highly effective contraception (double barrier method or barrier contraception in combination with hormonal or intrauterine contraceptive used by female partners) and not to donate sperm throughout the study and for 3 months after the last dose of the study medication for participants discontinued during the treatment period.

- Creatinine clearance < 60 mL/min as estimated using Cockcroft-Gault formula.
- Total bilirubin ≥ 34.2 µmol/L. (Participants with higher total bilirubin values may be included after the consultation with the Study Medical Monitor, if such elevation can be clearly attributed to Gilbert's syndrome associated with low-grade hyperbilirubinemia.)

Gilbert's syndrome, a benign disorder associated with low-grade hyperbilirubinemia, will not exclude patients from participation in this trial. Autoimmune hepatitis stigmata attributed to HDV infection in the opinion of the investigator are allowed.

- History of solid organ transplantation.
- Current alcohol abuse or alcohol abuse within 6 months prior to enrolment in this study; past or current drug addict.
- History of disease requiring regular use of systemic glucocorticosteroids (inhalative glucocorticosteroids are allowed) or other immunosuppressants.
- Pregnant or breast-feeding females.
- Participation in another clinical study with investigational drugs within 30 days prior to randomization.
- Receipt of bulevirtide previously, e.g. in clinical trials.
- Inability to follow protocol requirements and undergo all protocol procedures. NOTE: Participants with medical contraindication for liver biopsy are allowed to participate in this study. Such participants will exempt from liver biopsy requirements in this study.
Individuals receiving prohibited treatment at Screening cannot be included into the study unless this treatment is withdrawn prior to randomization.

Time Frame: Week 48
|
Combined response was defined as fulfilment of two conditions simultaneously: Undetectable (< lower limit of quantification (LLOQ, target not detected)) HDV RNA or decrease by ≥ 2 log10 IU/mL from baseline; and ALT normalization.

Percentage of Participants With Alanine Aminotransaminase (ALT) Normalization at Week 48
Time Frame: Week 48
|
ALT normalization was defined as an ALT value within the normal range, based on the central laboratories [Russian sites: ≤ 31 U/L for females and ≤ 41 U/L for males; all other sites: ≤ 34 U/L for females and ≤ 49 U/L for males])

Percentage of Participants Who Permanently Discontinued Study Drug Due to an Adverse Event (AE) (Week 48)
Time Frame: First dose date up to Week 48
|
An AE was defined as any untoward medical occurrence in a participant administered study drug and which did not necessarily had a causal relationship with the study drug.
An AE could therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not related to the study drug.

First dose date up to Week 48
|
Percentage of Participants Who Permanently Discontinued Study Drug Due to an Adverse Event (AE) (Week 96)
Time Frame: Delayed Treatment arm: Week 48 up to Week 96; Bulevertide 2mg/day and 10 mg/day arms: First dose date up to Week 96

Change From Baseline in Liver Stiffness, as Measured by Elastography at Week 96
Time Frame: Baseline, Week 96
|
A mixed-effects model for repeated measures (MMRM) was used to test null hypotheses of no difference compared to the control group.
Change from baseline in liver stiffness was the dependent variable using data for all post-baseline analysis visits up to Week 96.
The model included treatment, region, presence of cirrhosis, visit and treatment-by-visit interaction as fixed-effect factors, and baseline Liver stiffness as covariate
