GIVLAARI (givosiran sodium)

The pharmacokinetics of givosiran and its active metabolite [AS(N-1)3′ givosiran] were evaluated following single and multiple dosing in chronic high excreter subjects and AHP patients as summarized in Table 2. Table 2. Pharmacokinetic Parameters of Givosiran and Its Active Metabolite Givosiran AS(N-1)3′ Givosiran General Information Steady-State Exposure C max [Mean (CV%)] 321 ng/mL (51%) 123 ng/mL (64%) AUC 24 [Mean (CV%)] 4130 ng∙h/mL (43%) 1930 ng∙h/mL (63%) Dose Proportionality Steady-state...

The efficacy of GIVLAARI in patients with acute hepatic porphyria was evaluated in the ENVISION trial (NCT03338816), a randomized, double-blind, placebo-controlled, multinational study. ENVISION enrolled 94 patients with acute hepatic porphyria (AHP) (89 patients with AIP, 2 patients with variegate porphyria [VP], 1 patient with hereditary coproporphyria [HCP], and 2 patients with no identified mutation). Eligible patients were randomized 1:1 to receive once monthly subcutaneous injections of GIVLAARI 2.5 mg/kg or placebo during the 6-month double-blind period. In this study, inclusion criteri...

GIVLAARI is contraindicated in patients with known severe hypersensitivity to givosiran. Reactions have included anaphylaxis [see Warnings and Precautions (5.1) ]. Severe hypersensitivity to givosiran. ( 4 )

Anaphylactic Reaction: Ensure that medical support is available to appropriately manage anaphylactic reactions when administering GIVLAARI. Monitor for signs and symptoms. If anaphylaxis occurs, discontinue GIVLAARI and administer appropriate medical treatment. ( 5.1 ) Hepatic Toxicity: Measure liver function at baseline and periodically during treatment with GIVLAARI. Interrupt or discontinue treatment with GIVLAARI for severe or clinically significant transaminase elevations. ( 2.1 , 5.2 ) Ren...

7 DRUG INTERACTIONS Sensitive CYP1A2 and CYP2D6 Substrates: Avoid concomitant use with CYP1A2 and CYP2D6 substrates for which minimal concentration changes may lead to serious or life-threatening toxicities. ( 7.1 ) 7.1 Effect of GIVLAARI on Other Drugs Sensitive CYP1A2 and CYP2D6 Substrates Concomitant use of GIVLAARI increases the concentration of CYP1A2 or CYP2D6 substrates [see Clinical Pharma...
