Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8 °C for 1 week. Aliquots of reconstituted proteins are stable at < -20°C for 3 months.
Investigated for use/treatment in hepatitis (viral, C).
Examples of Clinical Use:
Hepatitis (viral, C).
Mechanism of action:
Interferons belong to a family of proteins known as cytokines that occur naturally in the human body. Cytokines control cellular processes, such as cell growth, activation, migration and aging. While the precise mechanism of action for interferon alpha is not known, research has demonstrated direct antiviral activity in patients with diseases like hepatitis C, as well as immune-modulating and direct antitumor effects in certain types of cancer.
Albinterferon Alfa-2B (Albumin-interferon alpha) is a treatment for chronic hepatitis C. It is a synthetic protein based on interferon alpha, which can clear viruses by activating the immune response. Alcaban uses human serum albumin as a carrier, which can increase its stability and bioavailability and effectively prolong its action time. Compared with ordinary interferon alpha, Alcapone is more effective, the frequency of administration is less, and the body burden is less on the patient. Albinterferon Alfa-2B is a biological agent for the treatment of chronic hepatitis B. It is a type of interferon-alpha 2b that binds to serum albumin and can treat hepatitis B by activating the immune system and suppressing viral replication.
The treatment regimen of Albinterferon Alfa-2B can reduce the number of frequent interferon injections and provide longer treatment intervals, thereby improving patient loyalty and quality of life. In clinical studies, researchers found that patients treated with mandatory combination therapy of Albinterferon Alfa-2B had a higher rate of viral negative conversion than those treated with interferon alone.
2. Application and Action Mechanism
Albinterferon Alfa-2B is commonly used to treat chronic hepatitis C. It is a drug that binds interferon alpha-2b to albumin, which makes it more bioavailable in the body. The drug inhibits viral replication through a variety of ways such as immune regulation, reducing hepatitis virus activity and viremia, thereby helping the liver to return to health. In addition, it can also be used to treat many other conditions, such as cancer, multiple myeloma, etc.
Albinterferon Alfa-2B is a recombinant interferon protein that can be used to treat hepatitis B virus infection. Its main mechanisms of action include promoting the response of the immune system, antiviral effects, and regulating cell growth and differentiation. Specifically, Albinterferon Alfa-2B boosts the activity of macrophages and natural killer cells, increasing their ability to attack viruses and infected cells. In addition, it can induce the cell to synthesize and release a variety of interferons, sending them to surrounding cells, thereby enhancing the antiviral ability of surrounding cells. In addition, as part of the glycoprotein Albinterferon Alfa-2B, it can stay in the body for a longer period of time, providing a sustained therapeutic effect. In conclusion, the mechanism of action of Albinterferon Alfa-2B is diverse, and it can effectively resist hepatitis B virus infection in a variety of ways.
3. Pros and cons of the application
Albinterferon Alfa-2B, a preparation of Interferon alpha bound to Albumin, is commonly used to treat chronic hepatitis B. It has the following advantages and disadvantages over other interferon alpha preparations:
Long-term performance: Due to its combination with albumin, interferon alpha can be slowly and continuously released, so that its half-life in the body is relatively long, thereby reducing the frequency of injection of patients and increasing patient compliance.
Stable effect: Studies have shown that the effect of Albinterferon Alfa-2B can be maintained at a stable level with regular administration, and there will be no large drug fluctuations like other interferon alpha preparations.
Less side effects: Due to its persistence and stability, side effects are less than other interferon alpha preparations.
Effective treatment: Albinterferon Alfa-2B is more reliable than other drugs in the treatment of hepatitis B.
Easy to use: The drug is an injection that only needs to be injected once a month, which is more convenient to use than other medications that need to be taken orally every day.
Higher cost: The price of Albinterferon Alfa-2B is relatively high compared to other interferon alpha preparations.
Possible therapeutic reactions: Due to its persistence, it may lead to therapeutic reactions in some patients, such as fatigue, myalgia, and other adverse reactions.
Many side effects: Albinterferon Alfa-2B may cause fever, fatigue, headache, nausea, and other side effects, and may cause anemia and leukopenia in serious cases.
Not suitable for all patients: Albinterferon Alfa-2B is not suitable for all patients with hepatitis B due to its side effects and resistance in some populations.
High cost: The price of this drug is more expensive, and the financial burden is larger for some patients.
Overall, although Albinterferon Alfa-2B has some advantages in some aspects, some disadvantages need to be weighed and selected in the treatment.
4. Approval status
Human Genome Sciences is developing Albuferon as a potential treatment for chronic hepatitis C. The drug is being investigated as an alternative to pegylated IFN-α-2a for the treatment of hepatitis C. Following the FDA's ruling, Novartis and Human Genome Sciences announced on October 5, 2010, that they had discontinued the development of the drug. Albumin-interferon alpha is also not FDA-approved and therefore is not used in the United States.
