Excipients with known effect
For the full list of excipients, see section 6.1.
3. PHARMACEUTICAL FORM
Solution for injection.
Clear, colourless to yellow solution (pH of approximately 7.0; osmolality: 275 – 295 mOsm/kg).
4. CLINICAL PARTICULARS4.1 Therapeutic indications
Givlaari is indicated for the treatment of acute hepatic porphyria (AHP) in adults and adolescents aged 12 years and older.
4.2 Posology and method of administration
Therapy should be initiated under the supervision of a healthcare professional experienced in the management of porphyria.
Posology
The recommended dose of Givlaari is 2.5 mg/kg once monthly, administered via subcutaneous injection. Dosing is based on actual body weight.
The patient dose (in mg) and volume (in mL) should be calculated as follows:
Patient body weight (kg) x dose (2.5 mg/kg) = total amount (mg) of medicinal product to be administered.
Total amount (mg) divided by vial concentration (189 mg/mL) = total volume of medicinal product (mL) to be injected.
Missed dose
If a dose is missed, treatment should be administered as soon as possible. Dosing should be resumed at monthly intervals following administration of the missed dose.
Dose modification for adverse reactions
In patients with clinically relevant transaminase elevations, who have dose interruption and subsequent improvement in transaminase levels, a dose resumption at 1.25 mg/kg once monthly could be considered (see sections 4.4 and 4.8).
Special populations
Elderly
No dose adjustment is required in patients aged > 65 years of age (see section 5.2).
Hepatic impairment
No dose adjustment is necessary in patients with mild hepatic impairment (bilirubin < 1× the upper limit of normal (ULN) and aspartate aminotransferase (AST) > PUL-N, or bilirubin > 1xULN to 1.5xULN). Givlaari has not been studied in patients with moderate or severe hepatic impairment (see section 4.4).
Renal impairment
No dose adjustment is necessary in patients with mild, moderate or severe renal impairment (estimated glomerular filtration rate [eGFR] > 15 to < 90 mL/min/1.73 m2). Givlaari has not been studied in patients with end-stage renal disease or patients on dialysis (see section 4.4).
Paediatric population
No dose adjustment is required for patients aged > 12 to < 18 years of age (see section 5.2). The safety and efficacy of Givlaari in children aged < 12 years of age has not been established. No data are available.
Method of administration
For subcutaneous use only.
This medicinal product is provided as a ready-to-use solution in a single use vial.
- • The required volume of Givlaari should be calculated based on the recommended weight-based dose.
- • The maximum acceptable single injection volume is 1.5 mL. If the dose is more than 1 mL, more than one vial will be needed.
- • Doses requiring more than 1.5 mL should be administered as multiple injections (the total monthly dose divided equally between syringes with each injection containing approximately the same volume) to minimise potential injection site discomfort due to injection volume.
- • This medicinal product should be injected subcutaneously into the abdomen; alternative injection sites include the thigh or upper arm.
- • For subsequent injections or doses, rotating the injection site is recommended.
- • This medicinal product should not be administered into scar tissue or areas that are reddened, inflamed, or swollen.
4.3 Contraindications
Severe hypersensitivity (e.g. anaphylaxis) to the active substance or to any excipients listed in section 6.1.
4.4 Special warnings and precautions for use
Patients with AHP subtypes other than acute intermittent porphyria (AIP)
The efficacy and safety data in patients with AHP subtypes other than AIP (hereditary coproporphyria (HCP), variegate porphyria (VP) and ALA dehydratase-deficient porphyria (ADP)) are limited (see section 5.1). This should be taken into consideration when assessing the individual benefit-risk in these rare AHP subtypes.
Anaphylactic reaction
In clinical studies, anaphylaxis occurred in one patient who had a history of allergic asthma and atopy (see section 4.8). Signs and symptoms of anaphylaxis should be monitored. If anaphylaxis occurs, administration of this medicinal product should be immediately discontinued and appropriate medical treatment should be instituted.
Transaminase elevations
Transaminase elevations have been observed in patients treated with givosiran. Transaminase elevations primarily occurred between 3 to 5 months following initiation of treatment (see section 4.8).
Liver function tests should be performed prior to initiating treatment. These tests should be repeated monthly during the first 6 months of treatment, and as clinically indicated thereafter. Interrupting or discontinuing treatment should be considered for clinically relevant transaminase elevations. In case of subsequent improvement in transaminase levels, resumption of treatment at a 1.25 mg/kg dose after interruption could be considered (see section 4.2). There are limited data on efficacy and safety of the lower dose, particularly in patients who previously experienced transaminase elevations. There are no data on sequentially increasing the 1.25 mg/kg dose to the 2.5 mg/kg dose after dose interruption for transaminase elevations (see section 4.8).
Effects on renal function
Increases in serum creatinine levels and decreases in eGFR have been reported during treatment with givosiran. In the placebo-controlled study, the median increase in creatinine at month 3 was
-
6.5 pmol/L (0.07 mg/dL) and resolved or stabilised by month 6 with continued monthly treatment with 2.5 mg/kg givosiran.
Progression of renal impairment has been observed in some patients with pre-existing renal disease. Careful monitoring of renal function during treatment is required in such cases.
Excipients
This medicinal product contains less than 1 mmol sodium (23 mg) per mL, that is to say essentially ‘sodium-free’.
4.5 Interaction with other medicinal products and other forms of interaction
In a clinical drug-drug interaction study, givosiran resulted in a weak to moderate reduction in activity of certain CYP450 enzymes in the liver thereby increasing plasma exposures:
- • CYP1A2: 1.3-fold increase in Cmax and 3.1-fold increase in AUCo vof caffeine
- • CYP2D6: 2.0-fold increase in Cmax and 2.4-fold increase in AUCo vof dextromethorphan
- • CYP2C19: 1.1-fold increase in Cmax and 1.6-fold increase in AUCo vof omeprazole
- • CYP3A4: 1.2-fold increase in Cmax and 1.5-fold increase in AUCo vof midazolam
- • CYP2C9: no effect on the exposure of losartan
Caution is recommended during the use of medicinal products that are substrates of CYP1A2 or CYP2D6 while on treatment with Givlaari as this medicinal product may increase or prolong their therapeutic effect, or alter their adverse event profiles. Consider decreasing the CYP1A2 or CYP2D6 substrate dosage in accordance with the approved product labelling.
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no or limited amount of data from the use of givosiran in pregnant women. Studies in animals have shown reproductive toxicity in the presence of maternal toxicity (see section 5.3). The use of this medicinal product could be considered during pregnancy taking into account the expected health benefit for the woman and potential risks to the foetus.
Breast-feeding
It is unknown whether givosiran is excreted in human milk. A risk to the newborns/infants cannot be excluded. Available pharmacodynamic/toxicological data in animals have shown excretion of givosiran in milk (see section 5.3). A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Givlaari therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.
Fertility
There are no data on the effects of givosiran on human fertility. No impact on male or female fertility was detected in animal studies (see section 5.3).
4.7 Effects on ability to drive and use machines
Givlaari has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Summary of the safety profile
The most frequently occurring adverse reactions reported in patients treated with givosiran are injection site reactions (ISRs) (36 %), nausea (32.4 %) and fatigue (22.5 %). The adverse reactions resulting in discontinuation of treatment were elevated transaminases (0.9 %) and anaphylactic reaction (0.9 %).

Description of selected adverse reactions
Liver function tests
In the placebo-controlled study, 7 (14.6 %) patients treated with givosiran and one (2.2 %) patient treated with placebo had an increased alanine aminotransferase (ALT) more than 3 times the ULN. In 5 patients treated with givosiran the transaminase elevations resolved with ongoing dosing at 2.5 mg/kg. Per protocol, one patient (with variegate porphyria) with ALT more than 8 times the ULN discontinued treatment and one patient with ALT more than 5 times the ULN interrupted treatment and resumed dosing at 1.25 mg/kg. ALT elevations in both patients resolved.
Injection site reactions
In placebo-controlled and open-label clinical studies, injection site reactions have been reported in 36 % of patients and generally have been mild or moderate in severity, mostly transient and resolved without treatment. The most commonly reported symptoms included erythema, pain, and pruritus. Injection-site reactions occurred in 7.8 % of injections and did not result in discontinuation of treatment. Three patients (2.7 %) experienced single, transient, recall reactions of erythema at a prior injection site with a subsequent dose administration.
Immunogenicity
In placebo-controlled and open-label clinical studies, 1 of 111 patients with AHP (0.9 %), developed treatment emergent anti-drug antibodies (ADA) during treatment with givosiran. ADA titres were low and transient with no evidence of an effect on clinical efficacy, safety, pharmacokinetic or pharmacodynamic profiles of the medicinal product.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in
4.9 Overdose
No case of overdose has been reported. In case of overdose, it is recommended that the patient be monitored for any signs or symptoms of adverse reactions and appropriate symptomatic treatment be instituted.
5. PHARMACOLOGICAL PROPERTIES5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Various alimentary tract and metabolism products, ATC code: A16AX16
Mechanism of action
Givosiran is a double-stranded small interfering ribonucleic acid (siRNA) that causes degradation of aminolevulinic acid synthase 1 (ALAS1 ) messenger ribonucleic acid (mRNA) in hepatocytes through RNA interference, resulting in a reduction of induced liver ALAS1 mRNA towards normal. This leads to reduced circulating levels of neurotoxic intermediates aminolevulinic acid (ALA) and porphobilinogen (PBG), the key causal factors of attacks and other disease manifestations of AHP.
Pharmacodynamic effects
In the placebo-controlled study in patients with AHP receiving givosiran 2.5 mg/kg once monthly (ENVISION), median reductions from baseline in urinary ALA and PBG of 83.7 % and 75.1 %, respectively, were observed 14 days after the first dose. Maximal reductions in ALA and PBG levels were achieved around month 3 with median reductions from baseline of 93.8 % for ALA and 94.5 % for PBG, and were sustained with repeated once monthly dosing.
Observed data and modelling demonstrated that once monthly dosing with 2.5 mg/kg givosiran resulted in a greater reduction and less fluctuation in ALA levels compared with doses less than 2.5 mg/kg or dosing once every 3 months.
Clinical efficacy
The efficacy of givosiran was evaluated in a randomised, double-blind, placebo-controlled, multinational study (ENVISION).
ENVISION
A total number of 94 patients with AHP (89 patients with acute intermittent porphyria (AIP), 2 patients with variegate porphyria (VP), 1 patient with hereditary coproporphyria (HCP), and 2 patients with no identified mutation in a porphyria-related gene) were randomised 1:1 to receive once monthly subcutaneous injections of givosiran 2.5 mg/kg or placebo during the 6-month double-blind period. Patients randomised to givosiran included 46 patients with AIP, 1 patient with VP, and 1 patient with HCP. In this study, inclusion criteria specified a minimum of 2 porphyria attacks requiring hospitalisation, urgent healthcare visit, or intravenous (IV) hemin administration at home in the 6 months prior to study entry. Hemin use during the study was permitted for the treatment of acute porphyria attacks. The median age of patients in the ENVISION study was 37.5 years (range 19 to 65 years); 89.4 % of patients were female, and 77.7 % were white. The treatment arms were balanced with respect to historical annualised porphyria attack rate (overall median baseline rate of 8 per year), prior hemin prophylaxis, use of opioid medicinal products, and patient-reported measures of chronic symptoms between attacks.
The major efficacy measure was the annualised attack rate (AAR) of composite porphyria attacks during the 6-month double-blind period and consisted of three components: attacks requiring hospitalisation, urgent healthcare visit, or IV hemin administration at home. This composite efficacy measure was evaluated as the primary endpoint in patients with AIP, and as a secondary endpoint in the overall population of patients with AHP. Treatment with this medicinal product resulted in a significant reduction of the AAR of composite porphyria attacks, compared with placebo, of 74 % in patients with AIP. Comparable results were seen in patients with AHP, with a reduction of 73 %. Consistent results were observed for each of the 3 components of the composite porphyria attack endpoint.
The results observed over 6 months were maintained through Month 12, with a median AAR (Q1, Q3) of 0.0 (0.0, 3.5) observed for patients with continued dosing with the medicinal product during the open-label extension period.
Givosiran reduced porphyria attacks compared to placebo in patients with AHP across all pre-specified subgroups, including age, sex, race, region, baseline body mass index (BMI), prior hemin prophylaxis use, historical attack rate, prior chronic opioid use when not having attacks, and the presence of prior chronic symptoms when not having attacks.
Additional clinical efficacy endpoints were studied in AIP patients and are summarised in

Paediatric population
The European Medicines Agency has waived the obligation to submit the results of studies with this medicinal product in all subsets of the paediatric population in the treatment of AHP (see section 4.2 and section 5.2 for information on paediatric use).
5.2 Pharmacokinetic properties
Absorption
Following subcutaneous administration, givosiran is rapidly absorbed with a time to maximum plasma concentration (tmax) of 0.5 to 2 hours. At the 2.5 mg/kg once monthly dose, the steady-state peak plasma concentrations of givosiran (Cmax) and area under the curve from time of dosing up to 24 hours after dosing (AUC24) were 321 ± 163 ng/mL and 4130 ± 1780 ng^h/mL, respectively, and corresponding values for the active metabolite were 123 ± 79.0 ng/mL and 1930 ± 1210 ng^h/mL, respectively.
Distribution
Givosiran is greater than 90 % bound to plasma proteins over the concentration range observed in humans at the 2.5 mg/kg once monthly dose. The population estimate for the steady state apparent volume of distribution (Vd/F) for givosiran and for the active metabolite was 10.4 L. Givosiran and its active metabolite distribute primarily to the liver after subcutaneous dosing.
Biotransformation
Givosiran is metabolised by nucleases to oligonucleotides of shorter lengths. Active metabolite AS(N-1)3’ givosiran (with equal potency as that of givosiran) was a major metabolite in plasma with 45 % exposure (AUC0–24) relative to givosiran at the 2.5 mg/kg once monthly dose. In vitro studies indicate that givosiran does not undergo metabolism by CYP450 enzymes.
Elimination
Givosiran and its active metabolite are eliminated from plasma primarily by metabolism with an estimated terminal half-life of approximately 5 hours. The population estimate for apparent plasma clearance was 36.6 L/h for givosiran and 23.4 L/h for AS(N-1)3’ givosiran. After subcutaneous dosing, up to 14 % and 13 % of the administered givosiran dose was recovered in urine as givosiran and its active metabolite, respectively, over 24 hours. The renal clearance ranged from 1.22 to 9.19 L/h for givosiran and 1.40 to 12.34 L/h for the active metabolite.
Linearity/non-linearity
Givosiran and its active metabolite exhibited linear pharmacokinetics in plasma over the 0.35 to 2.5 mg/kg dose range. At doses greater than 2.5 mg/kg, plasma exposure increased slightly greater than dose-proportionally. Givosiran exhibited time-independent pharmacokinetics with chronic dosing at the recommended dose regimen of 2.5 mg/kg once monthly. There was no accumulation of givosiran or the active metabolite in plasma after repeated once monthly dosing.
Pharmacokinetic/pharmacodynamic relationship
Plasma concentrations of givosiran are not reflective of the extent or duration of pharmacodynamic activity. Since givosiran is a liver targeted therapy, concentrations in plasma decline rapidly due to uptake by the liver. In the liver, givosiran exhibits a long half-life leading to extended duration of pharmacodynamic effect maintained over the monthly dosing interval.
Special populations
Elderly
No studies have been conducted in patients aged > 65 years. Age was not a significant covariate in the pharmacokinetics of givosiran.
Gender and race
In clinical studies there was no difference in the pharmacokinetics or pharmacodynamics of givosiran based on gender or race.
Hepatic impairment
Adult patients with mild hepatic impairment (bilirubin < 1xULN and AST > 1xULN, or bilirubin > IxULN to 1.5xULN) had comparable plasma exposure of givosiran and its active metabolite and similar pharmacodynamics (percent reduction in urinary ALA and PBG) as patients with normal hepatic function. No studies have been conducted in patients with moderate or severe hepatic impairment (see sections 4.2 and 4.4).
Renal impairment
Adult patients with mild renal impairment (eGFR > 60 to < 90 mL/min/1.73 m2), moderate renal impairment (eGFR > 30 to < 60 mL/min/1.73 m2) or severe renal impairment (eGFR > 15 to < 30 mL/min/1.73 m2) had comparable plasma exposure of givosiran and its active metabolite and similar pharmacodynamics (percent reduction in urinary ALA and PBG) as patients with normal renal function (eGFR > to 90 mL/min/1.73 m2). No studies have been conducted in patients with end-stage renal disease or patients with dialysis (see sections 4.2 and 4.4).
Paediatric population
Available data suggest that body weight but not age was a significant covariate in the pharmacokinetics of givosiran. At the 2.5 mg/kg dose, a similar exposure is expected in adolescents aged 12 years or older, as in adults with the same body weight.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, toxicity to reproduction and development. In the repeat-dose toxicity studies conducted in rats and monkeys, the rat was identified as the most sensitive species to givosiran-related effects, with the liver being identified as the primary target organ of toxicity in both the rat and monkey. No adverse findings were associated with chronic, weekly administration of givosiran to rats and monkeys at doses that achieved exposure multiples of 3.5– and 26.3-fold, respectively when compared to exposures achieved in patients receiving the maximum recommended human dose.
Genotoxicity/carcinogenicity
Givosiran did not exhibit a genotoxic potential in vitro and in vivo.
Animal studies have not been conducted to evaluate the carcinogenic potential of givosiran.
Reproductive toxicity
Embryo-foetal development studies have been performed in rats and rabbits during organogenesis. Givosiran showed marked maternal toxicity in rabbits (including mean maternal body weight loss) and resulted in increased post-implantation loss as a result of increased early resorptions and a low incidence of skeletal variations. These findings are considered an indirect effect, secondary to maternal toxicity. No adverse developmental effects were observed in rats administered the maternally toxic dose of approximately 9 times the normalised maximum recommended human dose.
In a postnatal development study in rats, there was no effect on growth and development of the offspring.
No adverse effects were observed in the fertility of male and female rats when administered with givosiran.
