Seladelpar Lysine (1 brand name, 1 dosage form, 1 route)
Available dosage forms: CAPSULE.
Routes of administration: ORAL.
Brand Names
- LIVDELZI
Indications and Usage
LIVDELZI is indicated for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have had an inadequate response to UDCA, or as monotherapy in patients unable to tolerate UDCA. This indication is approved under accelerated approval based on a reduction of alkaline phosphatase (ALP) [see Clinical Studies (14)]. Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).
Contraindications
None.
Adverse Reactions
The following clinically significant adverse reactions are described elsewhere in labeling: Fractures [see Warnings and Precautions (5.1)] Liver Test Abnormalities [see Warnings and Precautions (5.2)]
Mechanism of Action
Seladelpar is a peroxisome proliferator-activated receptor (PPAR)-delta (δ) agonist. However, the mechanism by which seladelpar exerts its therapeutic effects in patients with PBC is not well understood. Pharmacological activity that is potentially relevant to therapeutic effects includes inhibition of bile acid synthesis through activation of PPARδ, which is a nuclear receptor expressed in most tissues, including the liver. Published studies show that PPARδ activation by seladelpar reduces bile acid synthesis through Fibroblast Growth Factor 21 (FGF21)-dependent downregulation of CYP7A1, the key enzyme for the synthesis of bile acids from cholesterol.
Overdosage
PBC patients who received 5-times the recommended dosage or 20-times the recommended dosage of LIVDELZI experienced an increase in liver transaminases, muscle pain, and/or elevations in creatine phosphokinase, which resolved upon LIVDELZI discontinuation [see Warnings and Precautions (5.2)]. There is no specific treatment for overdose with LIVDELZI. General supportive care of the patient is indicated, as appropriate. If indicated, elimination of unabsorbed drug should be achieved by emesis or gastric lavage; usual precautions should be observed to maintain the airway. Because seladelpar is highly bound to plasma proteins, hemodialysis should not be considered.
