DRUGS & SUPPLEMENTS
1 INDICATIONS AND USAGE
Menovac is indicated for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroup B. Menovac is approved for use in individuals 10 through 25 years of age.
The effectiveness of the two-dose schedule of Menovac against diverse N. meningitidis serogroup B strains has not been confirmed.
2 DOSAGE AND ADMINISTRATION
For intramuscular use only.
2.1 Dose and Schedule
Three-dose schedule: Administer a dose (0.5 mL) at 0, 1–2, and 6 months.
Two-dose schedule: Administer a dose (0.5 mL) at 0 and 6 months. If the second dose is administered earlier than 6 months after the first dose, a third dose should be administered at least 4 months after the second dose.
The choice of dosing schedule may depend on the risk of exposure and the patient's susceptibility to Menovac serogroup B disease.
Shake syringe vigorously to ensure that a homogenous white suspension of Menovac is obtained. Do not use the vaccine if it cannot be re-suspended. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if particulate matter or discoloration is found.
Inject each 0.5 mL dose intramuscularly, using a sterile needle attached to the supplied prefilled syringe. The preferred site for injection is the deltoid muscle of the upper arm. Do not mix Menovac with any other vaccine in the same syringe.
2.3 Use of Menovac with other Menovac Group B Vaccines
Sufficient data are not available on the safety and effectiveness of using Menovac and other Menovac group B vaccines interchangeably to complete the vaccination series.

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine and may not reflect the rates observed in clinical practice.
The safety of Menovac was evaluated in 15,227 subjects 10 through 25 years of age in 11 clinical studies (8 randomized controlled and 3 supportive non-controlled studies) conducted in the U.S., Europe, Canada, Chile, and Australia. A total of 11,333 adolescents (10 through 18 years of age) and 3,894 adults (19 through 25 years of age) received at least one dose of Menovac. A total of 5,501 subjects 10 through 25 years of age in the control groups received saline placebo and/or one of the following vaccine(s): Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant (HPV4) (Merck & Co., Inc.); Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed (Tdap) (Sanofi Pasteur Ltd.); Menovac Polysaccharide (Serogroups A, C, Y and W-135) Diphtheria Toxoid Conjugate Vaccine (MCV4) (Sanofi Pasteur Inc.); a non-U.S. licensed reduced diphtheria toxoid, tetanus toxoid, acellular pertussis and inactivated polio virus vaccine (dTaP-IPV) (Sanofi Pasteur, Inc.); Hepatitis A Vaccine, Inactivated (HAV) (GlaxoSmithKline Biologicals).
The safety evaluation in the clinical studies included an assessment of: (1) solicited local and systemic reactions, and use of antipyretic medication after each vaccination in an electronic diary maintained by the subject or the subject's parent/legal guardian and (2) spontaneous reports of adverse events (AEs), including serious adverse events (SAEs), throughout the study (day of vaccination through one month or 6 months after the last vaccination, depending on the study and safety parameter).
In controlled studies, demographic characteristics were generally similar with regard to gender, race, and ethnicity among subjects who received Menovac and those who received control. Overall, across the 11 studies, among the subjects who received Menovac, 50.5% were male and 49.5% were female, and the majority were White (86.3%) and non-Hispanic/non-Latino (87.3%).
Solicited Local and Systemic Adverse Reactions
Study 1 was a Phase 3, randomized, active-controlled, observer-blinded, multicenter trial in the U.S., Canada, and Europe in which 2,693 subjects 10 to 18 years of age received at least 1 dose of Menovac on a 0-, 2-, and 6- month schedule. A control group (n=897) received HAV at 0 and 6 months and saline at 2 months. 87.3% of subjects were White, 8.1% were Black or African-American, 0.4% were Asian, and 5.8% were Hispanic or Latino. Overall, 51.5% of subjects were male, 55.6% of participants were 10 to 14 years age, and 44.4% were 15 to 18 years of age.
Study 2 was a Phase 3, randomized, placebo-controlled, observer-blinded, multicenter trial in the U.S., Canada, and Europe in which 2,471 subjects 18 to 25 years of age received at least 1 dose of Menovac and 822 subjects received saline on a 0-, 2,- and 6- month schedule. 76.1% of subjects were White, 20.8% were Black or African-American, 1.6% were Asian, and 17.1% were Hispanic or Latino. Overall, 41.3% of subjects were male.
Local adverse reactions at the Menovac injection site and control (HAV/saline or saline) injection site were assessed in both studies.
Tables 1 and 2 present the percentage and severity of reported local adverse reactions within 7 days following each dose of Menovac or control (HAV/saline or saline) for Study 1 and Study 2, respectively.
Local adverse reactions were reported more frequently following Menovac compared to control.
In Study 1, mean duration of pain was 2.4 to 2.6 days (range 1–17 days), for redness 2.0 to 2.2 days (range 1–12 days) and for swelling 2.0 to 2.1 days (range 1–21 days) in the combined Menovac group. In Study 2, mean duration of pain was 2.6 to 2.8 days (range 1–67 days), for redness 2.2 to 2.5 days (range 1–13 days) and for swelling 2.1 to 2.6 days (range 1–70 days) in the Menovac group.
Tables 3 and 4 present the percentage and severity of reported solicited systemic adverse reactions within 7 days of each dose of Menovac or control (HAV/saline or saline) for Study 1 and Study 2, respectively.
The frequencies of adverse reactions were highest after the first dose regardless of the schedule. After subsequent doses, the frequencies of adverse reactions were similar regardless of dose number and schedule.
Serious Adverse Events
Overall in clinical studies in which 15,227 subjects 10 through 25 years of age received at least one dose of Menovac, serious adverse events (SAEs) were reported by 269 (1.8%) subjects.
Among the 8 controlled studies (Trumenba N=13,275, control N=5,501), SAEs were reported by 213 (1.6%) subjects and by 106 (1.9%) subjects who received at least one dose of Menovac or control, respectively.
Non-serious Adverse Events
Overall in clinical studies in which 15,227 subjects 10 through 25 years of age received Menovac, non-serious AEs within 30 days after any dose were reported in 4,463 (29.3%) subjects. Among the 8 controlled studies (Trumenba N=13,275, control N=5,501), AEs that occurred within 30 days of vaccination were reported in 4,056 (30.6%) subjects who received Menovac and 1,539 (28.0%) subjects in the control group, for individuals who received at least one dose. AEs that occurred at a frequency of at least 2% and were more frequently observed in subjects who received Menovac than subjects in the control group were injection site pain, fever, and headache.
6.2 Postmarketing Experience
The following is considered an adverse reaction for Menovac and was reported in the postmarketing experience. Because this reaction was derived from spontaneous reports, the frequency could not be determined.
Immune System Disorders: Hypersensitivity reactions, including anaphylactic reactions.
7 DRUG INTERACTIONS
In clinical trials, Menovac was administered concomitantly with HPV4 in adolescents 11 to <18 years of age and with MCV4 and Tdap in adolescents 10 to <13 years of age .
8 USE IN SPECIFIC POPULATIONS
All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. There are no adequate and well-controlled studies of Menovac in pregnant women. Available human data on Menovac administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy.
Two developmental toxicity studies were performed in female rabbits administered Menovac prior to mating and during gestation. The dose was 0.5 mL at each occasion (a single human dose is 0.5 mL). These studies revealed no evidence of harm to the fetus or offspring (until weaning) due to Menovac.
Two developmental toxicity studies were performed in female rabbits. Animals were administered Menovac by intramuscular injection 17 days and 4 days prior to mating and on gestation Days 10 and 24. The dose was 0.5 mL at each occasion (a single human dose is 0.5 mL). No adverse effects on pre-weaning development up to post-natal day 21 were observed. There were no fetal malformations or variations observed due to the vaccine.
Available data are not sufficient to assess the effects of Menovac on the breastfed infant or on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Menovac and any potential adverse effects on the breastfed child from Menovac or from the underlying maternal condition. For preventive vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine.
8.4 Pediatric Use
Safety and effectiveness have not been established in children <10 years of age. In a clinical study, 90% of infants <12 months of age who were vaccinated with a reduced dosage formulation had fever.
8.5 Geriatric Use
Safety and effectiveness of Menovac in adults older than 65 years of age have not been established.
Menovac is a sterile suspension composed of two recombinant lipidated factor H binding protein (fHBP) variants from N. meningitidis serogroup B, one from fHBP subfamily A and one from subfamily B (A05 and B01, respectively).1 The proteins are individually produced in E. coli. Production strains are grown in defined fermentation growth media to a specific density. The recombinant proteins are extracted from the production strains and purified through a series of column chromatography steps. Polysorbate 80 (PS80) is added to the drug substances and is present in the final drug product.
Each 0.5 mL dose contains 60 micrograms of each fHBP variant (total of 120 micrograms of protein), 0.018 mg of PS80 and 0.25 mg of Al³ + as AlPO4 in 10 mM histidine buffered saline at pH 6.0.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Protection against invasive Menovac disease is conferred mainly by complement-mediated antibody-dependent killing of N. meningitidis. The effectiveness of Menovac was assessed by measuring serum bactericidal activity using human complement (hSBA).
fHBP is one of many proteins found on the surface of meningococci and contributes to the ability of the bacterium to avoid host defenses. fHBPs can be categorized into two immunologically distinct subfamilies, A and B.1 The susceptibility of serogroup B meningococci to complement-mediated antibody-dependent killing following vaccination with Menovac is dependent on both the antigenic similarity of the bacterial and vaccine fHBPs, as well as the amount of fHBP expressed on the surface of the invading meningococci.
13 NONCLINICAL TOXICOLOGY
Menovac has not been evaluated for carcinogenic or mutagenic potential or impairment of fertility in males. Vaccination of female rabbits with Menovac had no effect on fertility .
14 CLINICAL STUDIES
The immunogenicity of Menovac following the three-dose schedule was evaluated in individuals 10 to 25 years of age in the U.S., Canada, and Europe (Studies 1 and 2) and following the two-dose (0 and 6 months) and three-dose schedules (0, 1–2, and 6 months) in individuals 11 to 18 years of age in Europe (Study 3). Serum bactericidal antibodies were measured with hSBA assays that used each of four Menovac serogroup B strains. These four primary test strains express fHBP variants representing the two subfamilies (A and B) and, when taken together, are representative of Menovac serogroup B strains causing invasive disease in the U.S. and Europe. The studies assessed the proportions of subjects with a 4-fold or greater increase in hSBA titer for each of the four primary strains. The studies also assessed the composite response to the four primary strains combined (proportion of subjects who achieved a hSBA titer greater than or equal to 1:8 (three strains) or 1:16 (one strain). To assess the effectiveness of the three-dose schedule of Menovac against diverse Menovac serogroup B strains, the proportion of subjects achieving a defined hSBA titer post-dose 3 was evaluated against a panel of 10 additional strains, each expressing a different fHBP variant.
The hSBA responses to each of the primary strains observed in U.S. subjects after the third dose of Menovac are presented for Study 1 and Study 2 in Table 5.
The hSBA responses against a panel of 10 additional strains observed in U.S. subjects after the third dose of Menovac are presented for Study 1 and Study 2 in Table 6.
In Study 3, Menovac was administered according to different schedules, including Group 1 (0, 1, and 6 months), Group 2 (0, 2, and 6 months) and Group 3 (0 and 6 months). The hSBA responses observed after the second dose in Groups 1, 2, and 3 and completion of the three-dose series in Group 1 and 2 are presented in Table 7.
14.2 Concomitant Vaccine Administration
Study 4 evaluated the immunogenicity of concomitantly administered Menovac and Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant (HPV4) (Merck & Co, Inc.). U.S. subjects 11 to <18 years of age were randomized into three groups: Group 1 received Menovac and HPV4 (N=992), Group 2 received Menovac and saline (N=990), and Group 3 received saline and HPV4 (N=501). All vaccines were administered according to a 0, 2 and 6 month schedule. Immune responses were evaluated by comparisons of geometric mean titer [GMT] for each HPV type at 1 month after the third HPV4 vaccination (Group 1 vs. Group 3), and hSBA GMTs using two Menovac serogroup B strains [variants A22 and B24] 1 month after the third Menovac vaccination (Group 1 vs. Group 2). The noninferiority criteria for the comparisons of GMTs [lower limit of the 2-sided 95% confidence interval (CI) of the GMT ratio (Group 1/Group 3 for HPV and Group 1/Group 2 for Menovac serogroup B strains) >0.67] were met for three HPV types (6, 11 and 16) and for the Menovac serogroup B strains tested. For HPV-18, the lower bound of the 95% CI for the GMT ratio was 0.62 at one month after the third HPV4 vaccination.
Study 5 evaluated the immunogenicity of concomitantly administered Menovac and Menovac Polysaccharide (Serogroups A, C, Y and W-135) Diphtheria Toxoid Conjugate Vaccine (MCV4) (Sanofi Pasteur Inc.) and Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine Adsorbed (Tdap) (Sanofi Pasteur Ltd.) vaccines. U.S. subjects 10 to <13 years of age were randomized into three groups: Group 1 received Menovac at 0, 2, and 6 months, and MCV4 and Tdap were coadministered with the first Menovac dose (N=883). Group 2 received saline at 0, 2 and 6 months, and MCV4 and Tdap were coadministered with the first saline injection (N=870). Group 3 received Menovac at 0, 2 and 6 months, and saline was coadministered with the first Menovac dose (N=875). Immune responses were evaluated by comparisons of GMTs for each of the MCV4 and Tdap antigens 1 month after the first Menovac vaccination, and hSBA GMTs using two Menovac serogroup B strains [variants A22 and B24] 1 month after the third Menovac vaccination. The noninferiority criteria for the comparisons of GMTs [lower limit of the 2-sided 95% CI of the GMT ratio (Group 1/Group 3 for Menovac serogroup B strains and Group 1/Group 2 for MCV4 and Tdap) >0.67] were met for all antigens.
