Rotavirus vaccine, live

1 dose (1.5 ml) contains:

*Produced on Vero cells

Excipient with known effect:

This product contains sucrose 1073 mg (see section 4.4).

For the full list of excipients, see section 6.1.

Oral suspension.

Rotarix is a clear and colourless liquid.

Rotarix is indicated for the active immunisation of infants aged 6 to 24 weeks for prevention of gastro-enteritis due to rotavirus infection (see sections 4.2, 4.4 and 5.1).

The use of Rotarix should be based on official recommendations.

Posology

The vaccination course consists of two doses. The first dose may be administered from the age of 6 weeks. There should be an interval of at least 4 weeks between doses. The vaccination course should preferably be given before 16 weeks of age, but must be completed by the age of 24 weeks.

Rotarix may be given with the same posology to preterm infants born after at least 27 weeks of gestational age (see sections 4.8 and 5.1).

In clinical trials, spitting or regurgitation of the vaccine has rarely been observed and, under such circumstances, a replacement dose was not given. However, in the unlikely event that an infant spits out or regurgitates most of the vaccine dose, a single replacement dose may be given at the same vaccination visit.

It is recommended that infants who receive a first dose of Rotarix complete the 2-dose regimen with Rotarix. There are no data on safety, immunogenicity or efficacy when Rotarix is administered for the first dose and another rotavirus vaccine is administered for the second dose or vice versa.

Paediatric population

Rotarix should not be used in children over 24 weeks of age.

Method of administration

Rotarix is for oral use only.

Rotarix should under no circumstances be injected.

For instructions for the preparation or reconstitution of the medicinal product before administration, see section 6.6.

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Hypersensitivity after previous administration of rotavirus vaccines.

History of intussusception.

Subjects with uncorrected congenital malformation of the gastrointestinal tract that would predispose for intussusception.

Subjects with Severe Combined Immunodeficiency (SCID) disorder (see section 4.8).

Administration of Rotarix should be postponed in subjects suffering from acute severe febrile illness. The presence of a minor infection is not a contra-indication for immunisation.

The administration of Rotarix should be postponed in subjects suffering from diarrhoea or vomiting.

It is good clinical practice that vaccination should be preceded by a review of the medical history especially with regard to the contraindications and by a clinical examination.

There are no data on the safety and efficacy of Rotarix in infants with gastrointestinal illnesses or growth retardation. Administration of Rotarix may be considered with caution in such infants when, in the opinion of the physician, withholding the vaccine entails a greater risk.

No increased risk of intussusception was observed in clinical trials following administration of Rotarix when compared with placebo.

However, a small increased risk of intussusception in the 31-day period mostly within 7 days following the administration of the first dose of Rotarix cannot be excluded based on data from post-marketing safety studies (See section 4.8).

Therefore, as a precaution, healthcare professionals should follow-up on any symptoms indicative of intussusception (severe abdominal pain, persistent vomiting, bloody stools, abdominal bloating and/or high fever). Parents/guardians should be advised to promptly report such symptoms.

For subjects with a predisposition for intussusception, see section 4.3.

Asymptomatic and mildly symptomatic HIV infections are not expected to affect the safety or efficacy of Rotarix. A clinical study in a limited number of asymptomatic or mildly symptomatic HIV positive infants showed no apparent safety problems (see section 4.8).

Administration of Rotarix to infants who have known or suspected immunodeficiency should be based on careful consideration of potential benefits and risks.

Excretion of the vaccine virus in the stools is known to occur after vaccination with peak excretion around the 7th day. Viral antigen particles detected by ELISA were found in 50% of stools after the first dose of Rotarix lyophilised formulation and 4% of stools after the second dose. When these stools were tested for the presence of live vaccine strain, only 17% were positive. In two comparative controlled trials, vaccine shedding after vaccination with Rotarix liquid formulation was comparable to that observed after vaccination with Rotarix lyophilised formulation.

Cases of transmission of this excreted vaccine virus to seronegative contacts of vaccinees have been observed without causing any clinical symptom.

Rotarix should be administered with caution to individuals with immunodeficient close contacts, such as individuals with malignancies, or who are otherwise immunocompromised or individuals receiving immunosuppressive therapy.

Contacts of recent vaccinees should observe personal hygiene (e.g. wash their hands after changing child's nappies).

The potential risk of apnoea and the need for respiratory monitoring for 48-72h should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity.

As the benefit of the vaccination is high in this group of infants, vaccination should not be withheld or delayed.

A protective immune response may not be elicited in all vaccinees (see section 5.1).

The extent of protection that Rotarix might provide against other rotavirus strains that have not been circulating in clinical trials is currently unknown. Clinical studies from which efficacy data were derived were conducted in Europe, Central and South America, Africa and Asia (see section 5.1).

Rotarix does not protect against gastro-enteritis due to other pathogens than rotavirus.

No data are available on the use of Rotarix for post-exposure prophylaxis.

Rotarix should under no circumstances be injected.

The vaccine contains sucrose as an excipient. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this vaccine.

Rotarix can be given concomitantly with any of the following monovalent or combination vaccines [including hexavalent vaccines (DTPa-HBV-IPV/Hib)]: diphtheria-tetanus-whole cell pertussis vaccine (DTPw), diphtheria-tetanus-acellular pertussis vaccine (DTPa), Haemophilus influenzae type b vaccine (Hib), inactivated polio vaccine (IPV), hepatitis B vaccine (HBV), pneumococcal conjugate vaccine and meningococcal serogroup C conjugate vaccine. Clinical studies demonstrated that the immune responses and the safety profiles of the administered vaccines were unaffected.

Concomitant administration of Rotarix and oral polio vaccine (OPV) does not affect the immune response to the polio antigens. Although concomitant administration of OPV may slightly reduce the immune response to rotavirus vaccine, clinical protection against severe rotavirus gastro-enteritis was shown to be maintained in a clinical trial involving more than 4200 subjects who received Rotarix concomitantly with OPV.

There are no restrictions on the infant's consumption of food or liquid, either before or after vaccination.

Rotarix is not intended for use in adults. There are no data on the use of Rotarix during pregnancy and lactation.

Based on evidence generated in clinical trials, breast-feeding does not reduce the protection against rotavirus gastro-enteritis afforded by Rotarix. Therefore, breast-feeding may be continued during the vaccination schedule.

Summary of the safety profile

The safety profile presented below is based on data from clinical trials conducted with either the lyophilised or the liquid formulation of Rotarix.

In a total of four clinical trials, approximately 3800 doses of Rotarix liquid formulation were administered to approximately 1900 infants. Those trials have shown that the safety profile of the liquid formulation is comparable to the lyophilised formulation.

In a total of twenty-three clinical trials, approximately 106000 doses of Rotarix (lyophilised or liquid formulation) were administered to approximately 51000 infants.

In three placebo-controlled clinical trials (Finland, India and Bangladesh), in which Rotarix was administered alone (administration of routine paediatric vaccines was staggered), the incidence and severity of the solicited events (collected 8 days post-vaccination), diarrhoea, vomiting, loss of appetite, fever, irritability and cough/runny nose were not significantly different in the group receiving Rotarix when compared to the group receiving placebo. No increase in the incidence or severity of these events was seen with the second dose.

In a pooled analysis from seventeen placebo-controlled clinical trials (Europe, North America, Latin America, Asia, Africa) including trials in which Rotarix was co-administered with routine paediatric vaccines (see section 4.5), the following adverse reactions (collected 31 days post-vaccination) were considered as possibly related to vaccination.

List of adverse reactions

Adverse reactions reported are listed according to the following frequency:

Frequencies are defined as:

Very common (≥1/10)

Common (≥1/100, <1/10)

Uncommon (≥1/1,000, <1/100)

Rare (≥1/10,000, <1/1,000)

Clinical trial data

Gastrointestinal disorders

Common: diarrhoea

Uncommon: abdominal pain, flatulence

Skin and subcutaneous tissue disorders

Uncommon: dermatitis

General disorders and administration site conditions

Common: irritability

The risk of intussusception has been evaluated in a large safety trial conducted in Latin America and Finland where 63225 infants were enrolled. This trial gave evidence of no increased risk of intussusception in the Rotarix group when compared with the placebo group as shown in the table below.

*CI: confidence interval

Safety in preterm infants

In a clinical study, 670 pre-term infants from 27 to 36 weeks of gestational age were administered Rotarix lyophilised formulation and 339 received placebo. The first dose was administered from 6 weeks after birth. Serious adverse events were observed in 5.1% of recipients of Rotarix as compared with 6.8% of placebo recipients. Similar rates of other adverse events were observed in Rotarix and placebo recipients. No cases of intussusception were reported.

Safety in infants with human immunodeficiency (HIV) infection

In a clinical study, 100 infants with HIV infection were administered Rotarix lyophilised formulation or placebo. The safety profile was similar between Rotarix and placebo recipients.

Post marketing surveillance data

Because these events were reported spontaneously, it is not possible to reliably estimate their frequency.

Respiratory, thoracic and mediastinal disorders

Apnoea in very premature infants (≤ 28 weeks of gestation) (see section 4.4)

Gastrointestinal disorders

Intussusception (see section 4.4)

Haematochezia

Gastroenteritis with vaccine viral shedding in infants with Severe Combined Immunodeficiency (SCID) disorder

No case of overdose has been reported.

Pharmaco-therapeutic group: rotavirus diarrhoea vaccines, ATC code: J07BH01

Protective efficacy of the lyophilised formulation

In clinical trials, efficacy was demonstrated against gastro-enteritis due to rotavirus of the most common genotypes G1P[8], G2P[4], G3P[8], G4P[8] and G9P[8]. In addition, efficacy against uncommon rotavirus genotypes G8P[4](severe gastro-enteritis) and G12P[6] (any gastro-enteritis) has been demonstrated. These strains are circulating worldwide.

Clinical studies have been conducted in Europe, Latin America, Africa and Asia to evaluate the protective efficacy of Rotarix against any and severe rotavirus gastro-enteritis.

Severity of gastro-enteritis was defined according to two different criteria:

- the Vesikari 20-point scale, which evaluates the full clinical picture of rotavirus gastro-enteritis by taking into account the severity and duration of diarrhoea and vomiting, the severity of fever and dehydration as well as the need for treatment

or

- the clinical case definition based on World Health Organization (WHO) criteria

Clinical protection was assessed in the ATP cohort for efficacy, which includes all subjects from the ATP cohort for safety who entered into the concerned efficacy follow-up period.

Protective efficacy in Europe

A clinical study performed in Europe evaluated Rotarix given according to different European schedules (2, 3 months; 2, 4 months; 3, 4 months; 3, 5 months) in 4000 subjects.

After two doses of Rotarix, the protective vaccine efficacy observed during the first and second year of life is presented in the following table:

^† Severe gastro-enteritis was defined as a score ≥11 on the Vesikari scale

* Not statistically significant (p >0.05). These data should be interpreted with caution

Vaccine efficacy during the first year of life progressively increased with increasing disease severity, reaching 100% (95% CI: 84.7;100) for Vesikari scores ≥17.

Protective efficacy in Latin America

A clinical study performed in Latin America evaluated Rotarix in more than 20000 subjects. Severity of gastro-enteritis was defined according to WHO criteria. The protective vaccine efficacy against severe rotavirus gastro-enteritis requiring hospitalisation and/or rehydration therapy in a medical facility and the genotype specific vaccine efficacy after two doses of Rotarix are presented in the table below:

† Severe rotavirus gastro-enteritis was defined as an episode of diarrhoea with or without vomiting that required hospitalization and/or re-hydration therapy in a medical facility (WHO criteria)

* Not statistically significant (p ≥ 0.05). These data should be interpreted with caution

# The numbers of cases, on which the estimates of efficacy against G4P[8] were based, were very small (1 case in the Rotarix group and 2 cases in the placebo group)

A pooled analysis of five efficacy studies*, showed a 71.4% (95% CI:20.1;91.1) efficacy against severe rotavirus gastro-enteritis (Vesikari score ≥11) caused by rotavirus G2P[4] genotype during the first year of life.

* In these studies, the point estimates and confidence intervals were respectively: 100% (95% CI: -1858.0;100), 100% (95% CI: 21.1;100), 45.4% (95% CI: -81.5;86.6), 74.7 (95% CI :-386.2;99.6). No point estimate was available for the remaining study.

Protective efficacy in Africa

A clinical study performed in Africa (Rotarix: N = 2,974; placebo: N = 1,443) evaluated Rotarix given at approximately 10 and 14 weeks of age (2 doses) or 6, 10 and 14 weeks of age (3 doses). The vaccine efficacy against severe rotavirus gastro-enteritis during the first year of life was 61.2% (95% CI: 44.0;73.2). The protective vaccine efficacy (pooled doses) observed against any and severe rotavirus gastro-enteritis is presented in the following table :

† Severe gastro-enteritis was defined as a score ≥11 on the Vesikari scale

* Not statistically significant (p ≥ 0.05). These data should be interpreted with caution

Sustained efficacy up to 3 years of age in Asia

A clinical study conducted in Asia (Hong Kong, Singapore and Taiwan) (Total vaccinated cohort : Rotarix: N = 5,359; placebo: N = 5,349) evaluated Rotarix given according to different schedules (2, 4 months of age; 3, 4 months of age).

During the first year, significantly fewer subjects in the Rotarix group reported severe rotavirus gastro-enteritis caused by the circulating wild-type RV compared to the placebo group from 2 weeks after Dose 2 up to one year of age (0.0% versus 0.3%), with a vaccine efficacy of 100% (95% CI: 72.2; 100).

The protective vaccine efficacy after two doses of Rotarix observed against severe rotavirus gastro-enteritis up to 2 years of age is presented in the following table :

† Severe gastro-enteritis was defined as a score >11 on the Vesikari scale

* Not statistically significant (p ≥ 0.05). These data should be interpreted with caution

During the third year of life, there were no cases of severe RV gastro-enteritis in the Rotarix group (N=4,222) versus 13 (0.3%) in the placebo group (N=4,185). Vaccine efficacy was 100.0% (95% CI: 67.5; 100.0). The severe RV gastro-enteritis cases were due to RV strains G1P[8], G2P[4], G3P[8] and G9P[8]. The incidence of severe RV gastro-enteritis associated with the individual genotypes was too small to allow calculation of efficacy. The efficacy against severe RV gastro-enteritis requiring hospitalisation was 100% (95% CI: 72.4; 100.0).

Protective efficacy of the liquid formulation

Since the immune response observed after 2 doses of Rotarix liquid formulation was comparable to the immune response observed after 2 doses of Rotarix lyophilised formulation, the levels of vaccine efficacy observed with the lyophilised formulation can be extrapolated to the liquid formulation.

Immune response

The immunologic mechanism by which Rotarix protects against rotavirus gastro-enteritis is not completely understood. A relationship between antibody responses to rotavirus vaccination and protection against rotavirus gastro-enteritis has not been established.

The following table shows the percentage of subjects initially seronegative for rotavirus (IgA antibody titres < 20 U/ml) (by ELISA) with serum anti-rotavirus IgA antibody titers ≥20U/ml one to two months after the second dose of vaccine or placebo as observed in different studies with Rotarix lyophilised formulation.

In three comparative controlled trials, the immune response elicited by Rotarix liquid formulation was comparable to the one elicited by Rotarix lyophilised formulation.

Immune response in preterm infants

In a clinical study conducted in preterm infants, born after at least 27 weeks of gestational age, the immunogenicity of Rotarix was assessed in a subset of 147 subjects and showed that Rotarix is immunogenic in this population; 85.7% (95% CI: 79.0;90.9) of subjects achieved serum anti-rotavirus IgA antibody titers ≥ 20U/ml (by ELISA) one month after the second dose of vaccine.

Not applicable.
