What is Prolastin-C?

Prolastin-C Liquid may be used to replace missing alpha₁-proteinase inhibitor (alpha₁-PI) levels in people with a severe hereditary alpha₁-PI deficiency (also called alpha-1) who have symptoms of emphysema. Prolastin-C Liquid is a ready-to-use intravenous (into a vein) infusion given weekly for a person's life.

• Randomized controlled trials have not conclusively demonstrated a benefit for Prolastin-C on pulmonary exacerbations or the progression of emphysema.
• The long-term effects of augmentation (replacement) treatment with Prolastin-C are unknown.
• Prolastin-C should not be given to patients with lung disease who have not been diagnosed with severe Alpha-1 PI deficiency.

Prolastin-C Liquid is a concentrated, purified, form of the protein alpha₁ antitrypsin. Weekly administration raises plasma levels of alpha₁-PI although it is not known if this reduces pulmonary exacerbations or progression of emphysema. Alpha₁-PI deficiency is a rare genetic disease that is passed down through families. People with this condition do not make enough alpha₁-PI, a protein that protects your lungs from inflammation that can reduce lung function. 

Prolastin-C Liquid, a ready-to-use intravenous infusion, was FDA-approved on September 22, 2017. Prolastin-C, which required premixing, was first approved in February 1988 but is no longer available.

Prolastin-C side effects

Prolastin-C is well tolerated, and side effects are uncommon, but the most common side effects reported were diarrhea and fatigue.

Other side effects reported include:

• Upper respiratory tract infection
• Headaches
• Itchy skin
• Rash
• Nausea
• Edema
• Fever.

You may feel faint during the infusion and may need to rest for a short time afterward.

Serious side effects and warnings

Should not be given to people with a history of anaphylaxis or other severe systemic reactions to alpha₁-PI, Prolastin-C, or any of the inactive ingredients in the vial. Get emergency medical help if you have signs of an allergic reaction, such as hives, rash; confusion, feeling light-headed; fast heartbeats, chest tightness, difficulty breathing; or swelling of your face, lips, tongue, or throat.

Do not administer to immunoglobulin A (IgA deficient patients with antibodies against IgA).

Prolastin-C is not indicated for lung diseases that are not due to severe alpha₁-PI deficiency.

Prolastin-C is made from donated human plasma and may contain viruses or other infectious agents, although these are routinely screened for and treated to reduce the risk of contamination, there is still a small possibility it could transmit disease, such as the variant Creutzfeldt-Jakob disease (vCJD) and Creutzfeldt-Jakob disease (CJD). Ask your doctor about any possible risks.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
