Interventional
Description of intervention(s) / exposure
Experimental: Arm A - initial TAF treatment group - cirrhotic or non-cirrhotic CHB patients with hepatic decompensation and HBV NUC treatment naïve or experienced (except prior TAF) will receive initial treatment (Arm A) with TAF 25 mg/day.

Experimental: Experimental: SHR8735 cohort 3 - The subjects will receive a single dose of SHR8735 (high dose).

Experimental: Arm B - switch to TAF treatment group - cirrhotic or non-cirrhotic CHB patients with hepatic decompensation and currently under HBV NUC treatment (except TAF) with HBV DNA \< 20 IU/mL within 6 months prior screening will switch (Arm B) to TAF 25 mg/day

* Severe or uncontrolled comorbidities determined by the Investigator.
* Currently =grade 2 hepatic encephalopathy, currently or history (within 60 days) of variceal bleeding, hepatorenal syndrome, refractory ascites or spontaneous bacterial peritonitis; cytopenia of absolute neutrophil count < 750/mm3, or hemoglobin < 8 g/dL, or platelet <30000/mm3; or MELD score =30 at screening.
* Malignancy history including hepatocellular carcinoma, except basal cell skin cancer without recurrence for more than 5 years.
* Acute exacerbation of HBV, defined as an elevation of alanine aminotransferase (ALT) activity to more than 10 times the upper limit of normal and more than twice the baseline value.
* On any of the disallowed concomitant medications listed in the prior and concomitant medications list (pg. 16). Subjects on prohibited medications who are otherwise eligible will need a wash out period of at least 30 days prior to the Screening.
