Pegademase (Adagen) is a recombinant human adenosine deaminase enzyme used to treat severe combined immunodeficiency (SCID) caused by an inherited deficiency of the enzyme adenosine deaminase (ADA). SCID is a rare, life-threatening disorder in which the immune system is severely weakened. Treatment with Pegademase helps to restore immune system function in affected individuals. Pegademase is administered by intravenous (IV) infusion once a week for 6 weeks, followed by IV infusion every other week for 12 weeks. After that, Pegademase is usually given by subcutaneous (under the skin) injection once a month for the rest of the patient's life.
Pegademase is a medication used to treat a specific immune system disorder called Severe Combined Immunodeficiency (SCID) associated with adenosine deaminase (ADA) deficiency [1, 2, 3]. Here's a closer look at its key features:
- Type: Enzyme replacement therapy [1, 2, 3].
- Function: SCID with ADA deficiency is caused by a lack of the enzyme adenosine deaminase (ADA). Pegademase is a modified form of ADA derived from cows (bovine) [1, 2, 3]. It replaces the missing enzyme in the body, helping to regulate the immune system and prevent complications of SCID.
- Brand Name: Adagen [1, 2, 3].
- Administration: Pegademase is given by intramuscular injection, usually into a muscle, by a healthcare professional [1, 2, 3].
Important to Understand:
- Pegademase is not a cure for SCID, but rather a lifelong treatment to manage the condition [1, 2, 3].
- It's a critical medication for individuals with SCID caused by ADA deficiency, as it helps them fight infections and improve their overall health and well-being [1, 2, 3].
Here are some additional details about pegademase:
- How it Works: ADA normally breaks down a molecule called adenosine. In SCID with ADA deficiency, adenosine builds up to toxic levels, harming immune cells. Pegademase helps convert adenosine to a harmless molecule, preventing this toxicity and improving immune function [2, 3].
- Side Effects: Potential side effects can include pain, redness, or swelling at the injection site, as well as allergic reactions [1, 2, 3]. It's important to report any side effects to your doctor.
