4. CLINICAL PARTICULARS
4.1 Therapeutic indications
Veoza is indicated for the treatment of moderate to severe vasomotor symptoms (VMS) associatedwith menopause (see section 5.1).
4.2 Posology and method of administration
PosologyThe recommended dose is 45 mg once daily.
Benefit of long-term treatment should be periodically assessed since the duration of VMS can vary byindividual.
Missed doseIf a dose of Veoza is missed or not taken at the usual time, the missed dose should be taken as soon aspossible, unless there is less than 12 hours before the next scheduled dose. Individuals should return tothe regular schedule the following day.
ElderlyFezolinetant has not been studied for safety and efficacy in women initiating Veoza treatment over65 years of age. No dose recommendation can be made for this population.
Hepatic impairmentNo dose modification is recommended for individuals with Child-Pugh Class A (mild) chronic hepaticimpairment (see section 5.2).
Veoza is not recommended for use in individuals with Child-Pugh Class B (moderate) or C (severe)chronic hepatic impairment. Fezolinetant has not been studied in individuals with Child-Pugh Class C(severe) chronic hepatic impairment (see section 5.2).
Renal impairmentNo dose modification is recommended for individuals with mild (eGFR 60 to less than90 ml/min/1.73 m2) or moderate (eGFR 30 to less than 60 ml/min/1.73 m2) renal impairment (seesection 5.2).
Veoza is not recommended for use in individuals with severe (eGFR less than 30 ml/min/1.73 m2)renal impairment. Fezolinetant has not been studied in individuals with end-stage renal disease (eGFRless than 15 ml/min/1.73 m2) and is not recommended for use in this population (see section 5.2).
Paediatric populationThere is no relevant use of Veoza in the paediatric population for the indication of moderate to severe
VMS associated with menopause.
Method of administrationVeoza should be administered orally once daily at about the same time each day with or without foodand taken with liquids. Tablets are to be swallowed whole and not broken, crushed, or chewed due tothe absence of clinical data under these conditions.
4.3 Contraindications
− Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.− Concomitant use of moderate or strong CYP1A2 inhibitors (see section 4.5).− Known or suspected pregnancy (see section 4.6).
4.4 Special warnings and precautions for use
Medical examination/consultationPrior to the initiation or reinstitution of Veoza, a careful diagnosis should be made, and completemedical history (including family history) must be taken. During treatment, periodic check-ups mustbe carried out according to standard clinical practice.
Liver diseaseVeoza is not recommended for use in individuals with Child-Pugh Class B (moderate) or C (severe)chronic hepatic impairment. Women with active liver disease or Child-Pugh Class B (moderate) or C(severe) chronic hepatic impairment have not been included in the clinical efficacy and safety studieswith fezolinetant (see section 4.2) and this information cannot be reliably extrapolated. Thepharmacokinetics of fezolinetant has been studied in women with Child-Pugh Class A (mild) and B(moderate) chronic hepatic impairment (see section 5.2).
Drug-induced liver injury (DILI)
Elevations in serum alanine aminotransferase (ALT) levels and serum aspartate aminotransferase(AST) at least 3 times the upper limit of normal (ULN) were observed in women treated withfezolinetant, including serious cases with increased total bilirubin and symptoms suggesting liverinjury. Elevated liver function tests (LFTs) and symptoms suggestive of liver injury were generallyreversible on discontinuation of therapy. LFTs must be performed prior to treatment initiation withfezolinetant. Treatment should not be started if ALT or AST is ≥ 2 x ULN or if total bilirubin iselevated (e.g., ≥ 2 x ULN). LFTs must be performed monthly during the first three months oftreatment, then based on clinical judgement. LFTs must also be performed when symptoms suggestiveof liver injury occur.
Treatment should be discontinued in the following situations:− Transaminase elevations are ≥ 3 x ULN with: total bilirubin > 2 x ULN OR symptoms ofliver injury.− Transaminase elevations > 5 x ULN.
Monitoring of liver function should be maintained until they have normalised.
Patients should be informed about the signs and symptoms of liver injury and should be advised tocontact their doctor immediately once these occur.
Known or previous breast cancer or oestrogen-dependent malignancies
Women undergoing oncologic treatment (e.g., chemotherapy, radiation therapy, anti-hormone therapy)for breast cancer or other oestrogen-dependent malignancies have not been included in the clinicalstudies. Therefore, Veoza is not recommended for use in this population as the safety and efficacy areunknown.
Women with previous breast cancer or other oestrogen-dependent malignancies and no longer on anyoncologic treatment have not been included in the clinical studies. A decision to treat these womenwith Veoza should be based on a benefit-risk consideration for the individual.
Concomitant use of hormone replacement therapy with oestrogens (local vaginal preparations excluded)
Concomitant use of fezolinetant and hormone replacement therapy with oestrogens has not beenstudied, and therefore concomitant use is not recommended.
Seizures or other convulsive disorders
Fezolinetant has not been studied in women with a history of seizures or other convulsive disorders.
There were no cases of seizures or convulsive disorders during clinical studies. A decision to treatthese women with Veoza should be based on a benefit-risk consideration for the individual.
4.5 Interaction with other medicinal products and other forms of interaction
Effect of other medicinal products on fezolinetant
CYP1A2 inhibitorsFezolinetant is primarily metabolised by CYP1A2 and to a lesser extent by CYP2C9 and CYP2C19.
Concomitant use of fezolinetant with medicinal products that are moderate or strong inhibitors of
CYP1A2 (e.g., ethinyl oestradiol containing contraceptives, mexiletine, enoxacin, fluvoxamine)increase the plasma Cmax and AUC of fezolinetant.
Concomitant use of moderate or strong CYP1A2 inhibitors with Veoza is contraindicated (seesection 4.3).
Co-administration with fluvoxamine, a strong CYP1A2 inhibitor, resulted in an overall 1.8-foldincrease in fezolinetant Cmax and 9.4-fold increase in AUC; no change in tmax was observed. Given thelarge effect of a strong CYP1A2 inhibitor and supportive modelling, the increase in fezolinetantconcentrations is expected to be of clinical concern also following concomitant use with moderate
CYP1A2 inhibitors (see section 4.3). The increase in fezolinetant exposure was however not predictedto be clinically relevant following concomitant use with weak CYP1A2 inhibitors.
CYP1A2 inducersIn vivo data
Smoking (moderate inducer of CYP1A2) decreased fezolinetant Cmax to a geometric LS mean ratio of71.74%, while AUC decreased to a geometric LS mean ratio of 48.29%. The efficacy data did notpoint to relevant differences between smokers and non-smokers. No dose modification isrecommended for smokers.
TransportersIn vitro data
Fezolinetant is not a substrate of P-glycoprotein (P-gp). Major metabolite ES259564 is a substrate of
P-gp.
Effect of fezolinetant on other medicinal products
Cytochrome P450 (CYP) enzymes
In vitro data
Fezolinetant and ES259564 are not inhibitors of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19,
CYP2D6, and CYP3A4. Fezolinetant and ES259564 are not inducers of CYP1A2, CYP2B6, and
CYP3A4.TransportersIn vitro data
Fezolinetant and ES259564 are not inhibitors of P-gp, BCRP, OATP1B1, OATP1B3, OCT2, MATE1,and MATE2-K (IC50 > 70 µmol/l). Fezolinetant inhibited OAT1 and OAT3 with IC50 values of18.9 µmol/l (30 × Cmax,u) and 27.5 µmol/l (44 × Cmax,u), respectively. ES259564 does not inhibit OAT1and OAT3 (IC50 > 70 µmol/l).
4.6 Fertility, pregnancy and lactation
PregnancyVeoza is contraindicated during pregnancy (see section 4.3). If pregnancy occurs during use with
Veoza, treatment should be withdrawn immediately.
There are no or limited data from the use of fezolinetant in pregnant women. Studies in animals haveshown reproductive toxicity (see section 5.3). Perimenopausal women of childbearing potential shoulduse effective contraception. Non-hormonal contraceptives are recommended for this population.
Breast-feedingVeoza is not indicated during lactation.
It is unknown whether fezolinetant and its metabolites are excreted in human milk. Availablepharmacokinetic data in animals showed excretion of fezolinetant and/or its metabolites in animal milk(see section 5.3). A risk to the suckling child cannot be excluded. A decision must be made whether todiscontinue breast-feeding or to discontinue/abstain from Veoza therapy taking into account thebenefit of breast-feeding for the child and the benefit of therapy for the woman.
FertilityThere are no data on the effect of fezolinetant on human fertility. In the fertility study in female rats,fezolinetant did not affect fertility (see section 5.3).
4.7 Effects on ability to drive and use machines
Fezolinetant has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Summary of the safety profileThe most frequent adverse reactions with fezolinetant 45 mg were diarrhoea (3.2%) and insomnia(3.0%).
There were no serious adverse reactions reported at an incidence greater than 1% across the total studypopulation. On fezolinetant 45 mg, four serious adverse reactions were reported. The most seriousadverse reaction was an event of endometrial adenocarcinoma (0.1%).
The most frequent adverse reactions leading to dose discontinuation with fezolinetant 45 mg werealanine aminotransferase (ALT) increased (0.3%) and insomnia (0.2%).
Tabulated list of adverse reactionsThe safety of fezolinetant has been studied in 2203 women with VMS associated with menopausereceiving fezolinetant once daily in phase 3 clinical studies.
Adverse reactions observed during clinical studies and from spontaneous reporting are listed below byfrequency category in each system organ class. Frequency categories are defined as follows: verycommon (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1 000 to < 1/100); rare (≥ 1/10 000 to< 1/1 000); very rare (< 1/10 000); and not known (cannot be estimated from the available data).

In clinical trials, elevations in ALT levels > 3 x ULN occurred in 2.1% of women receivingfezolinetant compared to 0.8% of women receiving placebo. Elevations in AST levels > 3 x ULNoccurred in 1.0% of women receiving fezolinetant compared to 0.4% of women receiving placebo.
Serious cases with elevations of ALT and/or AST (> 10 x ULN) with concurrent elevations in bilirubinand/or alkaline phosphatase (ALP) were reported post-marketing. In some cases, elevated liverfunction tests were associated with signs and symptoms suggestive of liver injury such as fatigue,pruritus, jaundice, dark urine, pale faeces, nausea, vomiting, decreased appetite, and/or abdominal pain(see section 4.4).
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
4.9 Overdose
Doses of fezolinetant up to 900 mg have been tested in clinical studies in healthy women. At 900 mg,headache, nausea, and paraesthesia were observed.
In the case of overdose, the individual should be closely monitored, and supportive treatment shouldbe considered based on signs and symptoms.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Other gynaecologicals, other gynaecologicals, ATC code: G02CX06.
Mechanism of actionFezolinetant is a non-hormonal selective neurokinin 3 (NK3) receptor antagonist. It blocksneurokinin B (NKB) binding on the kisspeptin/neurokinin B/dynorphin (KNDy) neuron, which ispostulated to restore the balance in KNDy neuronal activity in the thermoregulatory centre of thehypothalamus.
Pharmacodynamic effectsIn postmenopausal women, with fezolinetant treatment, a transient decrease of luteinizing hormone(LH) levels was observed. No clear trends or clinically relevant changes in sex hormones measured(follicle-stimulating hormone (FSH), testosterone, oestrogen, and dehydroepiandrosterone sulphate) inpostmenopausal women were observed.
Clinical efficacy and safetyEfficacy: Effects on VMS
The effects of fezolinetant were studied in postmenopausal women with moderate to severe VMS intwo 12-week, randomised, placebo-controlled, double-blind phase 3 studies of identical design,followed by a 40-week extension treatment period (SKYLIGHT 1 - 2693-CL-0301 and SKYLIGHT 2- 2693-CL-0302). Women who had a minimum average of 7 moderate to severe VMS per day wereenrolled in the studies.
The study population included postmenopausal women defined as having amenorrhoea for ≥ 12consecutive months (70.1%) or amenorrhoea for ≥ 6 months with FSH > 40 IU/l (4.1%) or having hadbilateral oophorectomy ≥ 6 weeks prior to the screening visit (16.1%).
The study population included postmenopausal women with one or more of the following: priorhormone replacement therapy (HRT) use (19.9%), prior oophorectomy (21.6%), or prior hysterectomy(32.1%).
In the studies, a total of 1022 postmenopausal women (81% Caucasian, 17% Black, 1% Asian,24% Hispanic/Latina ethnicity, and aged ≥ 40 years and ≤ 65 years with an average age of 54 years)were randomised and stratified by smoking status (17% smokers).
The 4 co-primary efficacy endpoints for both studies were the change from baseline in moderate tosevere VMS frequency and severity to weeks 4 and 12 as defined in the Food and Drug Administration(FDA) and European Medicines Agency (EMA) guidelines. Each study demonstrated a statisticallysignificant and clinically meaningful (≥ 2 hot flashes per 24 hours) reduction from baseline in thefrequency of moderate to severe VMS to weeks 4 and 12 for fezolinetant 45 mg compared to placebo.
Data from the studies showed a statistically significant reduction from baseline in the severity ofmoderate to severe VMS to weeks 4 and 12 for fezolinetant 45 mg compared to placebo.
Results of the co-primary endpoint for change from baseline to weeks 4 and 12 in mean frequency ofmoderate to severe VMS per 24 hours from SKYLIGHT 1 and 2 and from pooled studies are shown in
Table 2.

Safety: Endometrial safety
In the long-term safety data (SKYLIGHT 1, 2, and 4), endometrial safety of fezolinetant 45 mg wasassessed by transvaginal ultrasound and endometrial biopsies (304 women had baseline and post-baseline endometrial biopsies during 52 weeks of treatment).
Endometrial biopsy assessments did not identify an increased risk of endometrial hyperplasia ormalignancy according to pre-specified criteria for endometrial safety. Transvaginal ultrasound did notreveal increased endometrial thickness.
Paediatric populationThe European Medicines Agency has waived the obligation to submit the results of studies withfezolinetant in all subsets of the paediatric population for the treatment of moderate to severe VMSassociated with menopause (see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
In healthy women, fezolinetant Cmax and AUC increased proportionally with doses between 20 and60 mg once daily.
After once-a-day dosing, steady-state plasma concentrations of fezolinetant were generally reached byday 2, with minimal fezolinetant accumulation. The pharmacokinetics of fezolinetant do not changeover time.
AbsorptionFezolinetant Cmax is usually achieved at 1 to 4 hours post-dose. No clinically significant differences infezolinetant pharmacokinetics were observed following administration with a high-calorie, high-fatmeal. Veoza may be administered with or without food (see section 4.2).
DistributionThe mean apparent volume of distribution (Vz/F) of fezolinetant is 189 l. The plasma protein bindingof fezolinetant is low (51%). The distribution of fezolinetant into red blood cells is almost equal toplasma.
BiotransformationFezolinetant is primarily metabolised by CYP1A2 to yield oxidised major metabolite ES259564.
ES259564 is approximately 20-fold less potent against human NK3 receptor. The metabolite-to-parentratio ranges from 0.7 to 1.8.
EliminationThe apparent clearance at steady-state of fezolinetant is 10.8 l/h. Following oral administration,fezolinetant is mainly eliminated in urine (76.9%) and to a lesser extent in faeces (14.7%). In urine, amean of 1.1% of the administered fezolinetant dose was excreted unchanged and 61.7% of theadministered dose was excreted as ES259564. The effective half-life (t1/2) of fezolinetant is 9.6 hoursin women with VMS.
Special populationsEffects of age, race, body weight, and menopause status
There are no clinically relevant effects on age (18 to 65 years), race (Black, Asian, Other), bodyweight (42 to 126 kg), or menopause status (pre-, post-menopause) on the pharmacokinetics offezolinetant.
Hepatic impairmentFollowing single-dose administration of 30 mg fezolinetant in women with Child-Pugh Class A (mild)chronic hepatic impairment, mean fezolinetant Cmax increased by 1.2-fold and AUCinf increased by 1.6-fold, relative to women with normal hepatic function. In women with Child-Pugh Class B (moderate)chronic hepatic impairment, mean fezolinetant Cmax decreased by 15% and AUCinf increased by 2-fold.
The Cmax of ES259564 decreased in both mild and moderate chronic hepatic impairment groups while
AUCinf and AUClast slightly increased less than 1.2-fold.
Fezolinetant has not been studied in individuals with Child-Pugh Class C (severe) chronic hepaticimpairment.
Renal impairmentFollowing single-dose administration of 30 mg fezolinetant, there was no clinically relevant effect onfezolinetant exposure (Cmax and AUC) in women with mild (eGFR 60 to less than 90 ml/min/1.73 m2)to severe (eGFR less than 30 ml/min/1.73 m2) renal impairment. The AUC of ES259564 was notchanged in women with mild renal impairment but increased approximately 1.7- to 4.8-fold inmoderate (eGFR 30 to less than 60 ml/min/1.73 m2) and severe renal impairment. Veoza is notrecommended for use in women with severe renal impairment or with end-stage renal disease becauseof lack of long-term safety data in this population.
Fezolinetant has not been studied in individuals with end-stage renal disease (eGFR lessthan 15 ml/min/1.73 m2).
5.3 Preclinical safety data
Effects in non-clinical studies were observed only at exposures considered sufficiently in excess of themaximum human exposure indicating little relevance to clinical use.
Repeated dose toxicityRepeated administration of fezolinetant to rats and monkeys showed the effects consistent with theprimary pharmacological action (oestrous cycle disruptions, the lack of ovarian activity, decreaseduterine and/or ovarian weight, uterine atrophy). These effects were observed at high exposure levels(> 10-fold of the anticipated clinical exposure at the human therapeutic dose of 45 mg). Furthermore,in rats, secondary effects were seen on the liver and thyroid which are considered to be an adaptiveresponse to the enzyme induction and in the absence of functional impairment and accompanyingnecrotic changes were considered non-adverse. The finding of thyroid follicular cell hyperplasia isconsidered secondary to the liver enzyme induction due to the increased thyroid hormone metabolism,resulting in the positive feedback to the pituitary for the stimulation of thyroid stimulating hormoneproduction and increased thyroid activity. It is generally accepted that rodents are more sensitive tothis type of liver-mediated thyroid toxicity than humans, thus these findings are not expected to beclinically relevant.
In monkeys, thrombocytopenia, sometimes associated with haemorrhagic episodes and regenerativeanaemia, was seen following repeated administration at high dose levels (> 60-fold of human exposureat the human therapeutic dose).
GenotoxicityFezolinetant and its major metabolite ES259564 showed no genotoxic potential in the in vitro bacterialreverse mutation test, in vitro chromosomal aberration test, and in vivo micronucleus test.
CarcinogenicityAn increase in the incidence of thyroid follicular cell adenoma was noted in a 2-year ratcarcinogenicity study (186-fold of human exposure at the human therapeutic dose). The increase isconsidered to be a rat specific effect secondary to the induction of hepatocyte metabolic enzymes anddoes not constitute a clinical carcinogenic risk.
Additionally, increased incidence of thymomas, which slightly exceeded the historical control range,was observed in both species. However, these findings were only noted at exposure levels significantlyin excess (> 50-fold) of the clinical exposure at the human therapeutic dose, and therefore are notexpected to be relevant to humans.
Reproductive and developmental toxicityFezolinetant had no effect on female fertility or early embryonic development in the rat study atexposure levels of 143-fold of human exposure at the human therapeutic dose.
In embryo-foetal development toxicity studies, embryo-lethality was noted at the exposure levels of128- and 174-fold at the human therapeutic dose in rats and rabbits, respectively. Rabbits also showedincreased late resorption and reduced foetal weight at the exposure levels of 28-fold at the humantherapeutic dose. Fezolinetant did not show teratogenic potential in either rats or rabbits. In the pre-and post-natal development study in rats, increased dose-responsive total litter loss/abortions wasobserved at the exposure levels of 36-fold of the anticipated clinical exposure at the maximumrecommended human dose, while reduced sexual maturation in male progeny was seen at the 204-foldexposure levels at the maximum recommended human dose.
Following administration of radiolabelled fezolinetant to lactating rats, the radioactivity concentrationin milk was higher than that in the plasma at all time points, indicating excretion of fezolinetant and/orits metabolites in the breast milk.
Environmental risk assessmentEnvironmental risk assessment studies have shown that fezolinetant may pose a risk to the aquaticenvironment (see section 6.6).
