Asviia Injection

1. Product Introduction

Asviia Injection is a prescription medication containing Pegaspargase (3750 IU), a modified enzyme used in the treatment of acute lymphoblastic leukemia (ALL), a type of cancer that affects the white blood cells. Pegaspargase is a pegylated form of the enzyme L-asparaginase, which breaks down the amino acid asparagine, depriving cancer cells of a vital nutrient required for their growth and survival.

Pegaspargase works by targeting leukemic cells that cannot synthesize asparagine and depend on its supply from the bloodstream. By eliminating asparagine, Asviia selectively kills these cancer cells while having a limited effect on normal cells. This targeted mechanism makes it an essential component in multi-agent chemotherapy regimens.

Administered as an intravenous or intramuscular injection by healthcare professionals in clinical settings, Asviia Injection is particularly favored for its long half-life and reduced frequency of administration compared to traditional L-asparaginase, offering enhanced convenience and patient compliance.

2. Uses of This Medicine

Asviia Injection is primarily used in the treatment of:

• Acute Lymphoblastic Leukemia (ALL):

  • In children, adolescents, and adults

  • As part of a combination chemotherapy protocol

  • Especially in patients who are allergic to native L-asparaginase or who require a longer-acting version

• Acute Lymphoblastic Lymphoma (a rare subtype of ALL):

  • Occasionally used in protocols that involve lymphoid malignancies with similar biological behavior to ALL

The medicine is usually included in induction and consolidation phases of ALL treatment protocols. It is crucial to note that Asviia Injection should only be administered under strict medical supervision by oncologists or hematologists experienced in cancer chemotherapy.

3. Benefits of This Medicine

Asviia Injection offers several significant advantages in leukemia treatment:

• Targeted Anti-Cancer Action:
  Pegaspargase targets leukemia cells by depleting asparagine, an amino acid essential for the survival of malignant lymphoblasts. This selectivity helps reduce damage to healthy cells.

• Prolonged Half-Life:
  The pegylated form of the enzyme allows for longer action, meaning fewer injections are required (typically every 2-3 weeks), which reduces the burden on patients and caregivers.

• Reduced Immunogenicity:
  Compared to native L-asparaginase, Pegaspargase has a lower risk of allergic reactions, making it safer for long-term use, especially in patients who are hypersensitive to conventional asparaginase.

• Improved Tolerability:
  Many patients tolerate Pegaspargase better than its non-pegylated counterparts. Its reduced toxicity profile enables its use in pediatric and adolescent populations with fewer side effects.

• Enhanced Survival Outcomes:
  When used in combination with other chemotherapy drugs, Pegaspargase significantly improves remission rates and survival in patients with ALL.

4. Side Effects

Like all medications, Asviia Injection may cause side effects. However, not all individuals experience them, and many are manageable under medical supervision.

Common Side Effects:

• Nausea and vomiting

• Fatigue or weakness

• Loss of appetite

• Increased liver enzymes (seen in blood tests)

• Blood clotting issues

• Abdominal pain

Serious Side Effects (require immediate medical attention):

• Pancreatitis: Inflammation of the pancreas; symptoms include severe abdominal pain, nausea, and vomiting.

• Thrombosis: Blood clots can form in veins or arteries, leading to swelling, pain, or even life-threatening complications.

• Allergic Reactions: Rash, itching, swelling, breathing difficulties, or anaphylaxis in rare cases.

• Hepatotoxicity: Liver dysfunction or liver failure in extreme cases.

• Hyperglycemia: Elevated blood sugar levels, particularly in patients with predisposing risk factors.

Patients receiving Asviia should be regularly monitored with blood tests to check liver function, blood sugar, amylase/lipase levels, and coagulation status.

5. Frequently Asked Questions (FAQ)

Q1: How is Asviia Injection administered?
A: It is given either through intravenous infusion (IV) or as an intramuscular (IM) injection by a healthcare professional in a hospital or clinical setting.

Q2: How often is Asviia Injection given?
A: Due to its long-acting nature, it is typically administered once every 14–21 days, depending on the chemotherapy protocol.

Q3: Can Asviia be used in children?
A: Yes, Asviia is commonly used in pediatric oncology, particularly for childhood ALL, as it has been proven effective and relatively safe under strict supervision.

Q4: What precautions should be taken before using Asviia?
A: Inform your doctor about any history of pancreatitis, liver problems, bleeding disorders, diabetes, or allergies. Regular monitoring is essential throughout treatment.

Q5: Can Asviia be used in patients allergic to L-asparaginase?
A: Yes, Pegaspargase is often used in patients who have developed hypersensitivity to native L-asparaginase due to its modified, less immunogenic structure.
