Overview
Bulevirtide-gmod is an NTCP-directed HDV attachment inhibitor. Bulevirtide as an acetate salt, is a 47-amino acid protein with a fatty acid myristoyl residue at the N-terminus and an amidated C-terminus. All chiral amino acids are in the L-configuration. The counter ion acetate is bound in ionic form to basic groups of the peptide molecule in a nonstoichiometric ratio. Bulevirtide acetate has a molecular formula of C 248 H 355 N 65 O 72 (net) and a molecular weight of 5398.9 Da (average mass, net), and has the following structural formula: HEPCLUDEX (bulevirtide-gmod) for injection is a sterile, preservative-free, white to off-white lyophilized powder or cake for subcutaneous injection after reconstitution. Each single-dose vial delivers 8.5 mg of bulevirtide-gmod (equivalent to approximately 8.6 mg of bulevirtide acetate). The inactive ingredients are histidine (3.3 mg), mannitol (51 mg), and sucrose (8.5 mg), and may include hydrochloric acid and/or sodium hydroxide to adjust the pH to 8.5. HEPCLUDEX requires reconstitution prior to administration by subcutaneous injection [see Dosage and Administration (2.2) ]. Chemical Structure
How to use
Recommended dosage in adults: HEPCLUDEX 8.5 mg once daily by subcutaneous injection. ( 2.1 ) Instructions for Use should be followed for preparation and administration of HEPCLUDEX. ( 2.2 ) 2.1 Recommended Dosage in Adults The recommended dosage in adults is HEPCLUDEX 8.5 mg once daily administered by subcutaneous injection. HEPCLUDEX should be continued as long as it is associated with a response to treatment. The optimal treatment duration is unknown. In all patients, manage the underlying hepatitis B virus (HBV) infection as clinically appropriate. If a dose is missed, that dose should be taken as soon as possible. However, if it is almost time for the next dose, skip the missed dose and resume the original schedule. 2.2 Dose Preparation and Administration See the HEPCLUDEX full Instructions for Use for details on the preparation and administration of HEPCLUDEX. Healthcare professionals should train patients or caregivers on the proper reconstitution and administration of HEPCLUDEX, and subcutaneous injection techniques. Consider preparation and administration of the first dose under healthcare professional supervision. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Aseptically reconstitute HEPCLUDEX lyophilized powder or cake by adding 1 mL of Sterile Water for…
Side effects
The following adverse reactions are discussed in other sections of the labeling: Exacerbation of Hepatitis D and B After Discontinuation of Treatment [see Warnings and Precautions (5.1) ]. The most common adverse reactions (incidence greater than or equal to 10%, all grades) observed with treatment with HEPCLUDEX are injection site reactions, headache, abdominal pain, fatigue, and pruritus . ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gilead Sciences, Inc. at 1-800-GILEAD-5 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The overall safety profile of HEPCLUDEX is based on Phase 2 and Phase 3 data from 165 adults with chronic HDV infection without cirrhosis or with compensated cirrhosis who received at least 48 weeks of HEPCLUDEX 8.5 mg subcutaneous injection once daily. Trial MYR301 was a Phase 3 randomized, multi-center, open-label, parallel-arm trial in 101 adults. In this trial, 50 adults received 8.5 mg HEPCLUDEX daily for 144 weeks and 51 adults who were in the Delayed Treatment group received no HDV treatment for the first 48 weeks; 50 adults in the Delayed Treatment…
Warnings
Important safety information
WARNING: POSTTREATMENT SEVERE ACUTE EXACERBATION OF HEPATITIS D and B Severe acute exacerbations of hepatitis D and hepatitis B may occur after HEPCLUDEX is discontinued, especially in patients with cirrhosis, who may be at increased risk of more severe flares or progression to hepatic decompensation. Monitor hepatic function closely with both clinical and laboratory follow-up, including hepatitis B virus (HBV) DNA and hepatitis delta virus (HDV) RNA viral load, for at least six months in patients who discontinue HEPCLUDEX. Resumption of antiviral therapy may be warranted [see Warnings and Precautions (5.1) ] . WARNING: POSTTREATMENT SEVERE ACUTE EXACERBATION OF HEPATITIS D and B See full prescribing information for complete boxed warning . Severe acute exacerbations of hepatitis D and hepatitis B may occur after HEPCLUDEX is discontinued, especially in patients with cirrhosis, who may be at increased risk of more severe flares or progression to hepatic decompensation. Monitor hepatic function closely with both clinical and laboratory follow-up, including hepatitis B virus (HBV) DNA and hepatitis delta virus (HDV) RNA viral load, for at least six months in patients who discontinue HEPCLUDEX. Resumption of antiviral therapy may be warranted. ( 5.1 )
Interactions
Effects of HEPCLUDEX on Other Drugs No CYP enzyme or transporter mediated inhibition or induction by bulevirtide is anticipated at clinically relevant concentrations [see Clinical Pharmacology (12.3) ]. 7.2 Effects of Other Drugs on HEPCLUDEX Due to peptide catabolism of bulevirtide, the drug-drug interaction potential of other drugs to impact bulevirtide pharmacokinetics, via CYP enzymes, is low [see Clinical Pharmacology (12.3) ].
