Frequently asked questions about ALG-000184

What is ALG-000184 used for?

ALG-000184 is an investigational small molecule being developed for chronic hepatitis B infection. It is being studied in healthy volunteers and in patients with chronic hepatitis B, including HBeAg-positive and HBeAg-negative adult subjects. The drug is currently in clinical development and has not been approved by regulatory authorities.

What does ALG-000184 target?

ALG-000184 targets the hepatitis B virus (HBV). It is a small molecule designed to act against the virus that causes chronic hepatitis B infection. The drug is being evaluated for its safety, tolerability, pharmacokinetics, and pharmacodynamics in clinical trials.

Who makes ALG-000184?

ALG-000184 is being developed by Aligos Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol ALGS. The company is conducting clinical trials to evaluate the drug's safety and efficacy in treating chronic hepatitis B infection.

What phase is ALG-000184 in?

ALG-000184 is in Phase 1 and Phase 2 clinical development. One Phase 1 trial has been completed, another Phase 1 trial is active but not recruiting, and a Phase 2 trial is currently recruiting participants. The drug is investigational and has not been approved by the FDA.

What clinical trials is ALG-000184 in?

ALG-000184 is being studied in three clinical trials. NCT04536337 is a completed Phase 1 study in healthy volunteers and chronic hepatitis B subjects. NCT06672900 is an active Phase 1 study in healthy volunteers. NCT06963710 is a recruiting Phase 2 study comparing ALG-000184 with tenofovir disoproxil fumarate in chronic hepatitis B patients.

Is ALG-000184 the same as tenofovir disoproxil fumarate?

No, ALG-000184 is not the same as tenofovir disoproxil fumarate. Tenofovir disoproxil fumarate is a comparator drug used in a Phase 2 clinical trial to evaluate the efficacy and safety of ALG-000184 in untreated adult subjects with chronic hepatitis B infection.
