4.1 Pregnancy

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral should not be administered to pregnant females [See Pregnancy (8.1)]. It is not known whether Adenovirus Type 4 and Type 7 Vaccine, Live, Oral can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Naturally occurring infection with adenoviruses has been associated with fetal harm. Pregnancy should be avoided for 6 weeks following receipt of vaccine.

4.2 Severe Allergic Reaction

Severe allergic reaction (e.g., anaphylaxis) to any component of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral is a Contraindication [See Description (11)].

4.3 Inability to Swallow

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral should not be administered to individuals incapable of swallowing each entire tablet, whole, without chewing. Chewing a tablet could expose the upper respiratory tract to live adenovirus leading to disease [See Mechanism of Action (12.1)].

5.1 Altered Immunocompetence

The safety and effectiveness of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral in immunocompromised individuals has not been evaluated.

5.2 Shedding and Transmission

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral contains live viruses that are shed in the stool and can cause disease if transmitted.

People who come in close contact with those who were vaccinated, including other vaccinees, may be exposed to the virus present in the stool and may develop disease [See Pharmacodynamics (12.2)].

Persons vaccinated with Adenovirus Type 4 and Type 7 Vaccine, Live, Oral should exercise caution when in close contact with children less than 7 years of age and immunocompromised individuals such as those with HIV infection and cancer, or those receiving immunosuppressive therapy during the 28 day period of viral shedding following the vaccination [See Use in Specific Populations (8.3) and Pharmacodynamics (12.2)].

Vaccinees should exercise caution when in close contact with pregnant women during the 28 day period of shedding because fetal harm may result if pregnant women are exposed to adenovirus [See Pregnancy (8.1) and Pharmacodynamics (12.2)].

5.3 Planning for Pregnancy

Use effective contraception for 6 weeks after vaccination to avoid pregnancy [See Pregnancy (8.1)].

5.4 Human Serum Albumin

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral contains albumin, a derivative of human blood. It is present at concentrations of <0.3 mg/tablet. Based on effective donor screening, and product manufacturing processes, it carries an extremely remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD) also is considered extremely remote. No cases of transmissions of viral diseases or CJD have ever been identified for human albumin.

6.1 Clinical Trials Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a vaccine cannot be directly compared to the rates in the clinical trials of another vaccine and may not reflect the rates observed in practice.

Multicenter Safety and Efficacy Trial

Safety of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral was evaluated in a multicenter, double-blind, randomized, placebo-controlled study that enrolled 3031 subjects who received vaccine and 1009 subjects who received placebo (lactose tablets). The study was conducted in healthy male (63%) and female (37%) active duty US Army and Navy military recruits during their basic training. The population had a mean age of 21 years, with an age range of 17 to 42 years. Race was 62% Caucasian, 18% African-American, 11% Hispanic, 3% Asian and 6% other. Subjects in both groups were administered other vaccines concomitantly with Adenovirus Type 4 and Type 7 Vaccine, Live, Oral.  The specific vaccines that each subject received varied and were dependent on their immunization history.  The vaccines that were co-administered included Hepatitis A Vaccine, Inactivated (Merck & Co., Inc.), Hepatitis A Inactivated and Hepatitis B (Recombinant) Vaccine (GlaxoSmithKline Biologicals), Hepatitis B Vaccine (Recombinant) (Merck & Co., Inc.), Human Papillomavirus Quadrivalent (Types 6, 11, 16, 18) Vaccine, Recombinant (Merck & Co., Inc.), Influenza Vaccine, Live, Intranasal (MedImmune, LLC), Influenza Virus Vaccine (Sanofi Pasteur, Inc.), Measles, Mumps, and Rubella Virus Vaccine Live (Merck & Co., Inc.), Meningococcal (Groups A, C, Y and W-135) Polysaccharide, Diphtheria Toxoid Conjugate Vaccine (Sanofi Pasteur, Inc.), Meningococcal Polysaccharide Vaccine (Groups A, C, Y and W-135 Combined) (Sanofi Pasteur, Inc.), Poliovirus Vaccine Inactivated (Sanofi Pasteur, SA), Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, Adsorbed (Sanofi Pasteur, Ltd.), Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, Adsorbed (GlaxoSmithKline Biologicals), Typhoid Vi Polysaccharide Vaccine (Sanofi Pasteur, SA), Varicella Virus Vaccine Live (Merck & Co., Inc.), Yellow Fever Vaccine (Sanofi Pasteur, Inc.).

Serious Adverse Events

No deaths were reported during the multicenter safety and efficacy trial.

Serious adverse events in vaccine recipients included hematuria, gastroenteritis, febrile gastroenteritis, gastritis, pneumonia, and hematochezia.

Fifty-seven serious adverse events (SAEs) were reported during the six month study period with 39 reported between 0 and 56 days following treatment and 18 reported during the 56 to 180 day follow-up period. Thirty-five subjects (1.2%) who received vaccine (25 between 0 and 56 days from the date of vaccination, 10 during the 56 to 180 day follow-up period) and 12 subjects (1.2%) who received placebo (9 between 0 and 56 days from the date of treatment, 3 during the 56 to 180 day follow-up period) experienced at least one SAE. The SAEs occurring between Day 0 and Day 56 post-vaccination in the vaccine group, possibly associated with the receipt of the vaccine product as determined by the investigator, were as follows: one subject with hematuria and gastroenteritis (at 9 days post vaccination), one subject with febrile gastroenteritis (at 4 days post vaccination, one subject with gastritis (at 23 days post vaccination), and one subject with pneumonia (at 23 days post vaccination); one SAE (hematochezia) in the vaccine group occurred during the 56 to 180 day follow-up period and was determined to be possibly related to the vaccine product. A placebo recipient developed febrile acute respiratory disease where adenovirus Type 4 vaccine strain was detected from posterior pharyngeal and tonsillar swabbing and characterized by serotyping and polymerase chain reaction analysis [See Warnings and Precautions: Shedding and Transmission (5.2)].

Overall, the percentage of subjects who experienced at least one adverse event during the 56 day study period was 91.2% in the Adenovirus Type 4 and Type 7 Vaccine, Live, Oral group compared to 93.9% in the placebo group. No subject in either treatment arm discontinued the study due to an adverse event. Adverse reactions were captured on a 2-Week Daily Diary (for a minimum of the first 780 subjects) or a 1-Week Daily Diary (for all remaining subjects) and were also reported at each study visit up to Day 56 after vaccination. Any reported AEs for Days 0-14 for the safety cohort and for Days 0-7 for the remaining subjects were defined as "solicited" because they were almost exclusively recorded directly by the subject from a pre-defined diary checklist. Although pyrexia was defined as “solicited,” it was not on the pre-defined diary checklist. Any AEs reported spontaneously as part of the regular study visit or during a spontaneous visit to the clinic, for Days 15-56 for the safety cohort and Days 8-56 for the remaining subjects were designated as "non-solicited."

Solicited Adverse Reactions

The following solicited adverse reactions were collected through daily diaries: stuffy nose, cough, sore throat, stomach pain, headache, diarrhea, nausea, and joint pain (within 14 days post enrollment for subjects in the initial safety cohort (n=878) and within 7 days post enrollment all subjects (n= 4040) for the rest of safety population). Those solicited adverse reactions reported by ≥ 5 % of subjects in either the vaccine or placebo treatment groups are presented in Table 1.

*MedDRA Preferred Term

Pyrexia (temp ≥ 100.5°F) within 7 days, was reported to occur in 1.4% (42/3030) of vaccine recipients and 0.5% (5/961) of placebo recipients who were not diagnosed with ARD. During the 8-14 days post vaccination, rates of pyrexia were 0.6% (4/659) and 1.1% (2/170) in vaccine and placebo recipients, respectively.

Non-Solicited Adverse Reactions

Non-solicited adverse reactions that occurred Days 15-56 in the safety cohort and Days 8-56 for all remaining subjects, reported by ≥ 5 % of subjects in either the vaccine or placebo treatment groups, are presented in Table 2.

*MedDRA Preferred Term

Less common (less than 5%) adverse reactions reported in the clinical trial in military recruits receiving Adenovirus Type 4 and Type 7 Vaccine, Live, Oral, versus placebo, respectively included rhinorrhea (128 [4.22%] vs. 25 [2.48%]), pain in extremity (130 [4.29%] vs. 37 [3.67%]), and pyrexia (fever greater than or equal to 100.5 °F) (126 [4.16%] vs. 49 [4.86%]).

Safety and Immunogenicity Trial

Five SAEs were reported among the 58 subjects in the safety and immunogenicity trial. Two SAEs occurred among the vaccine recipients: one case of pneumonia reported on Day 33 of the follow-up period, and a report of appendicitis occurring on Day 118 of follow-up period. Three SAEs were reported among placebo recipients: one case of pneumonia on Day 10 and one case of upper respiratory infection reported on Day 14, and a right thigh abscess reported at Day 91.

6.2 Postmarketing Experience

The following adverse reactions have been identified during post approval use of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.

Immune System Disorders: Hypersensitivity reactions (including anaphylaxis)

Nervous System Disorders: Guillain-Barré syndrome

7.1 Concomitant Vaccine Administration

In clinical studies Adenovirus Type 4 and Type 7 Vaccine, Live, Oral was administered concurrently with other vaccines [See Adverse Reactions (6.1)]. Data were not available to assess whether Adenovirus Type 4 and Type 7 Vaccine, Live, Oral interferes with the immune response to the other vaccines.

7.2 Immunosuppressive Therapies

There are no data regarding the use of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral concomitantly with immunosuppressive therapies, e.g., irradiation, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids (used in greater than physiologic doses) [See Warnings and Precautions: Altered Immunocompetence (5.1)].

8.1 Pregnancy

Risk Summary

Do not administer Adenovirus Type 4 and Type 7 Vaccine, Live, Oral to pregnant females [See Contraindications (4.1)]. It is not known whether Adenovirus Type 4 and Type 7 Vaccine, Live, Oral can cause fetal harm when administered to a pregnant woman. Naturally occurring infection with adenoviruses has been associated with fetal harm.

Pregnancy should be avoided for 6 weeks following receipt of vaccine.

In the US 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.

Clinical Considerations

Labor and Delivery

There is no information regarding the effect of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral on labor and delivery. Fecal shedding during delivery may result in vaccine virus transmission to the newborn infant.

Data

Human Data

Five pregnancies were reported among women enrolled in the multicenter safety and efficacy trial of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral. Four of the subjects (3 vaccine recipients and 1 placebo recipient) were estimated to have conceived 2 to 13 days prior to vaccination. One subject (vaccine recipient) conceived approximately 21 weeks after vaccination. The deliveries to all five of the subjects were of healthy infants at estimated gestational ages between 36 and 40 weeks.

8.2 Lactation

Risk Summary

There are no data on the presence of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral in human milk, effects on milk production, or on the breastfed infant.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Adenovirus Type 4 and Type 7 Vaccine, Live, Oral and any potential adverse effects on the breastfed infant from Adenovirus Type 4 and Type 7 Vaccine, Live, Oral or from the underlying maternal condition. For preventive vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine.

8.3 Females and Males of Reproductive Potential

Pregnancy Testing

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral is contraindicated for use in pregnant women [See Pregnancy (4.1)]. Females of reproductive potential should have a pregnancy test prior to treatment with Adenovirus Type 4 and Type 7 Vaccine, Live, Oral.

Contraception

Advise females of reproductive potential to use effective contraception during treatment with Adenovirus Type 4 and Type 7 Vaccine, Live, Oral and for 6 weeks following receipt of vaccine.

8.4 Pediatric Use

The safety and effectiveness of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral has not been evaluated in the age groups from birth through age 16.

8.5 Geriatric Use

Clinical studies of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral did not include subjects aged 65 and over to determine whether they respond differently from younger subjects. There are no data to support use of this vaccine in geriatric (person ≥ 65 years) populations.

12.1 Mechanism of Action

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral is a live oral vaccine that replicates in the intestinal tract and induces immunity in persons with low or no pre-existing neutralizing antibodies.

12.2 Pharmacodynamics

Vaccine Virus Shedding

Fecal shedding of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral strain viruses was evaluated in a safety and immunogenicity study of 58 subjects (30 vaccine recipients and 28 placebo recipients) [See Clinical Studies (14)]. Stool or rectal swabs and throat swabs were collected on Day 0, 7, 14, 21, 28 and 56. Vaccine virus strains were shed in the stool as early as day 7 following vaccination. Eight of 30 vaccine recipients (27%) tested positive at least once for Adenovirus Type 4 fecal shedding; 18 of 30 vaccine recipients (60%) tested positive for Adenovirus Type 7 fecal shedding. No adenovirus shedding was detectable in any subject by 28 days following vaccination. Vaccine strain virus was not detected in the throat of any subject.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Adenovirus Type 4 and Type 7 Vaccine, Live, Oral has not been evaluated for carcinogenic or mutagenic potential, or for impairment of male fertility.

14.1 Multicenter Safety and Efficacy Trial

A multicenter, double-blind, randomized, placebo-controlled study in US military recruits evaluated the safety and efficacy of Adenovirus Type 4 and Type 7 Vaccine, Live, Oral to prevent wild Type 4 adenovirus-associated febrile acute respiratory disease (ARD) and to induce neutralizing antibody to Type 7 adenovirus. A seroconversion endpoint rather than prevention of clinical disease was used to assess efficacy of the Type 7 adenovirus vaccine component of this product as the incidence of febrile ARD due to Type 7 adenovirus was not anticipated to be high enough to permit a meaningful statistical assessment of the clinical effect of this vaccine component. Subjects were randomized to either the vaccine group or the placebo group in a 3:1 ratio. 4041 subjects were randomized, and 4040 subjects were analyzed. Females and males aged 17 or older and in good physical health were included in the study. No subjects were immunosuppressed or being treated with systemic immunosuppressive therapy. Baseline serology data is presented in Table 3.

Adenovirus Type 4 Efficacy and Immunogenicity

Febrile Acute Respiratory Disease (ARD): The results for the primary analysis of vaccine efficacy (VE) for adenovirus Type 4 and rate of wild Type 4 febrile ARD, are summarized in Table 4. Cases were defined as subjects with one or more clinical signs and symptoms of ARD (mild to severe: sore throat, cough, rhinorrhea, nasal congestion, rales or rhonchi), an oral temperature > 100.5°F, and throat culture positive for wild Type 4 adenovirus infection. Vaccine type Adenovirus was distinguished from wild type by a Polymerase Chain Reaction (PCR) assay.

Seroconversion Rate: Adenovirus Type 4 seroconversion rate is presented in Table 5. Seroconversion is defined as the development of a Type 4 neutralizing antibody titer of greater or equal to 1:8 at Day 26 after vaccination in subjects whose baseline titer was less than 1:4.

Adenovirus Type 7 Immunogenicity

Febrile Acute Respiratory Disease: No Type 7 adenovirus-associated febrile or afebrile ARD cases were reported for either placebo or vaccine groups. This was expected given the estimated attack rate of adenovirus Type 7 in the military base training setting at the time of the study. Seroconversion was the primary evaluation of Type 7 effectiveness.

Seroconversion Rate: Results for the primary analysis of adenovirus Type 7 efficacy, seroconversion rate at Day 26, are summarized in Table 6. Seroconversion is defined as the development of a Type 7 neutralizing antibody titer of greater or equal to 1:8 at Day 26 after vaccination in subjects whose baseline titer was less than 1:4.
