Bulevirtide is in clinical development for the treatment of chronic hepatitis Delta virus infection in adult patients with compensated liver disease. Hepatitis D is a viral infection of the liver that is dependent on the patient already being infected with hepatitis B virus. The co-infection is thought to be more severe and cause more damage to the liver than hepatitis B alone. Currently there are limited treatment options for the treatment of patients with chronic hepatitis D virus infection.
Bulevirtide is a synthetic protein that is designed to specifically to bind to and block, a receptor present on liver cells. This receptor is essential to hepatitis B and D viruses entering and infecting the liver cells. By blocking the entry of hepatitis D virus, bulevirtide limits the virus ability to spread and replicate, reducing the symptoms of infection. If licensed, bulevirtide will become the first-in-class potent entry inhibitor offering a new therapeutic option for patients suffering from chronic hepatitis delta virus infection for whom limited therapeutic regimens are available.
Cabotegravir and rilpivirine tablets are in development as an oral lead-in therapy for a period of approximately one month as a short-term oral bridging treatment for Human Immunodeficiency Virus 1 (HIV-1) patients that are considered eligible for the long-acting injectable cabotegravir and rilpivirine therapy. HIV is a type of viral infection caused by a type of virus referred to as a retrovirus. HIV-1 is the most common and highly communicable type of HIV. HIV is a lifelong, chronic disease that nowadays can be managed with antiretroviral therapies (ARTs). Since HIV virus can quickly adapt and become resistant, a combination of ART drugs is normally used. Usually patients take between one and 4 or 6 tablets a day. Failing to do so will result in a weakened immune system and increased vulnerability to infections.
