Frequently asked questions about Bylvay and PFIC

What is progressive familial intrahepatic cholestasis?

Progressive familial intrahepatic cholestasis (PFIC) is a spectrum of rare, genetic disorders that can cause liver damage. The way PFIC affects the liver can cause itch (pruritus), which can be severe in some patients.

What is pruritus?

Doctors may describe the itch from PFIC using this term. Pruritus (pronounced proo-rahy-tuhs) is a medical term for itching.

What is Bylvay?

Bylvay is a medicine to treat cholestatic pruritus (itch) in patients with Alagille syndrome as young as 12 months of age and in patients with progressive familial intrahepatic cholestasis (PFIC) as young as 3 months of age.

Limitation of Use:  
Bylvay may not be effective in a subgroup of PFIC type 2 patients with specific ABCB11 variants resulting in non-functional or complete absence of the bile salt export pump protein

How is Bylvay thought to work?

Bylvay is a type of medication called an ileal bile acid transporter (IBAT) inhibitor. While the exact way Bylvay reduces itch isn’t fully understood, IBAT inhibition may reduce bile acid buildup as measured by bile acid in the blood. The buildup of bile acids in the liver and the bloodstream is believed to be the possible cause of itch in PFIC.
