  • 6 ADVERSE REACTIONS

    6.1 Clinical Studies Experience

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

    Head Lice Infestations

    Spinosad Topical Suspension was studied in two randomized, active-controlled trials (N=552) in subjects with head lice; Table 1 presents selected adverse events, regardless of relationship to Spinosad Topical Suspension, that occurred in at least 1% of subjects.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Spinosad, the active ingredient in Spinosad Topical Suspension, is not absorbed systemically following topical application, and maternal use is not expected to result in fetal exposure to the drug. Spinosad Topical Suspension contains benzyl alcohol. Topical benzyl alcohol is unlikely to be absorbed through the skin in clinically relevant amounts; therefore, maternal use is not expected to result in fetal exposure to the drug [see Clinical Pharmacology (12.3)].

    In animal reproduction studies, no adverse embryofetal effects were seen at oral doses of spinosad up to 200 mg/kg/day in pregnant rats or 50 mg/kg/day in pregnant rabbits administered during the period of organogenesis (see Data). The available data do not allow the calculation of relevant comparisons between the systemic exposure of spinosad in animal studies to the systemic exposure that would be expected in humans after topical use of Spinosad Topical Suspension.

    The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk for 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.

    Data

    Animal Data

    Systemic embryofetal development studies were conducted in rats and rabbits. Oral doses of 10, 50 and 200 mg/kg/day spinosad were administered during the period of organogenesis (gestational days 6 – 15) to pregnant female rats. No adverse embryofetal effects were noted at any dose. Maternal toxicity occurred at 200 mg/kg/day. Oral doses of 2.5, 10, and 50 mg/kg/day spinosad were administered during the period of organogenesis (gestational days 7 – 19) to pregnant female rabbits. No adverse embryofetal effects were noted at any dose. Maternal toxicity occurred at 50 mg/kg/day.

    A two-generation dietary reproduction study was conducted in rats. Oral doses of 3, 10, and 100 mg/kg/day spinosad were administered to male and female rats from 10-12 weeks prior to mating and throughout mating, parturition, and lactation. No reproductive/developmental toxicity was noted at doses up to 10 mg/kg/day. In the presence of maternal toxicity, increased dystocia in parturition, decreased gestation survival, decreased litter size, decreased pup body weight, and decreased neonatal survival occurred at a dose of 100 mg/kg/day.

    8.2 Lactation

    Risk Summary

    Spinosad, the active ingredient in Spinosad Topical Suspension, is not systemically absorbed by the mother following topical application. Therefore, breastfeeding is not expected to result in the exposure of the child to spinosad [see Clinical Pharmacology (12.3)] . Advise breastfeeding women to remove Spinosad Topical Suspension from the breast with soap and water before breastfeeding to avoid direct infant exposure to Spinosad Topical Suspension.

    Spinosad Topical Suspension contains benzyl alcohol. Topical benzyl alcohol is unlikely to be absorbed through the skin of breastfeeding women in clinically relevant amounts; therefore, breastfeeding is not expected to result in exposure of the infant to Spinosad Topical Suspension [see Clinical Pharmacology (12.3)]. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Spinosad Topical Suspension and any potential adverse effects on the breastfed child from Spinosad Topical Suspension, or from the underlying maternal condition.

    8.4 Pediatric Use

    Head Lice Infestation

    The safety and effectiveness of Spinosad Topical Suspension for the topical treatment of head lice infestation have been established in pediatric patients 6 months of age and older [see Clinical Pharmacology (12.3) and Clinical Studies (14)] .

    Spinosad Topical Suspension is not recommended in pediatric patients below the age of 6 months because of the potential for increased systemic absorption due to a high ratio of skin surface area to body mass and the potential for an immature skin barrier.

    Spinosad Topical Suspension contains benzyl alcohol. Intravenous administration of benzyl alcohol has been associated with serious adverse reactions and death in neonates and low birth-weight infants. The "gasping syndrome" (characterized by central nervous system depression, metabolic acidosis, gasping respirations, and high levels of benzyl alcohol and its metabolites found in the blood and urine) has been associated with benzyl alcohol dosages >99 mg/kg/day in neonates and low-birthweight infants when administered intravenously. Additional symptoms may include gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse.

    The minimum amount of benzyl alcohol at which toxicity may occur is not known. Premature and low-birthweight infants, as well as patients receiving high dosages of benzyl alcohol, may be more likely to develop toxicity [see Warning and Precautions (5.1)] .

    Scabies Infestation

    The safety and effectiveness of Spinosad Topical Suspension for the topical treatment of scabies infestation have been established in pediatric patients 4 years of age and older. Use of Spinosad Topical Suspension in this age group is supported by Trial 1 and Trial 2 which included 165 pediatric subjects ages 4 to 17 years old with scabies infestation. The safety and efficacy were generally consistent between pediatric and adult patients. [see Clinical Pharmacology (12.3) and Clinical Studies (14)] .

    The safety and effectiveness of Spinosad Topical Suspension have not been established in pediatric patients less than 4 years of age with scabies infestation.

    8.5 Geriatric Use

    Clinical studies of Spinosad Topical Suspension did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

  • 10 OVERDOSAGE

    No specific antidotes for spinosad overdosage are known. If oral ingestion occurs, contact Poison Control (1-800-222-1222) for latest recommendations and seek medical attention immediately.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Spinosad causes neuronal excitation in insects. After periods of hyperexcitation, lice and mites become paralyzed and die.

    12.2 Pharmacodynamics

    The pharmacodynamics of Spinosad Topical Suspension has not been studied.

    12.3 Pharmacokinetics

    Head Lice Infestations

    An open-label, single-center trial was conducted over a period of seven days to determine the pharmacokinetic profile of spinosad 1.8% in pediatric subjects with head lice infestation. Fourteen (14) subjects, 4 – 15 years of age, with head lice were enrolled into the trial. All subjects applied a single topical (scalp) treatment of spinosad 1.8% for 10 minutes, after which the test article was washed off, and subjects underwent plasma sampling. Results demonstrated that spinosad was below the limit of quantitation (3 ng/mL) in all samples. Plasma concentration of benzyl alcohol was not determined in these subjects.

    An open-label, two-center trial was conducted over a period of 23 days to determine the pharmacokinetic profile of spinosad 0.9% and the ingredient benzyl alcohol in pediatric subjects with a head lice infestation. Twenty-six (26) subjects between 6 months to 4 years of age were enrolled into the study per protocol. All subjects applied a single topical (scalp) treatment of spinosad 0.9% for 10 minutes, after which the test article was washed off, and subjects underwent plasma sampling over a 12 hour period. Plasma spinosad concentrations were below the limit of quantitation (3 ng/mL) in all samples.

    Benzyl alcohol was quantifiable (above 1 μg/mL) in a total of 8 plasma samples in 6 out of 26 subjects (25%): four out of 12 subjects in the 6 months to <2 years age group and two out of 14 subjects in the 2 to 4 years age group. The highest observed concentration was 2.37 μg/mL. Benzyl alcohol concentrations at 12 hours post-treatment were below limit of quantification (1 μg/mL) for all subjects.

    Scabies Infestations

    An open-label multi-center trial was conducted to determine the pharmacokinetic profile of spinosad 0.9% and the ingredient benzyl alcohol in pediatric subjects with scabies infestation. The PK bioavailability study was completed in 19 pediatrics subjects 5 to 16 years of age. All subjects applied a single topical body treatment of spinosad 0.9% from the neck down to the soles of the feet and allowed treatment to remain on the body for a minimum of 6 hours after which the test article was washed off. Subjects underwent plasma sampling over a 12-hour period after treatment. Plasma spinosad concentrations were below the limit of quantification (3 ng/mL) in all samples.

    Benzyl alcohol was quantifiable (above 1 μg/mL) in a total of 9 plasma samples in 6 out of 19 subjects (32%): in 3 out of 10 subjects in the 5 to 9 year age group and in 3 out of 9 subjects in the 10 to 16 years age group. The highest observed concentration was 3.94 μg/mL at 0.5 hours post-treatment but was below limit of quantification at 1 hour post-treatment for one subject in the 10 to 16 years age group. There were two subjects with a benzyl alcohol concentration at 3 hours post-treatment with the highest value of 3.53 μg/mL for one subject in the 5 to 9 years age group. Plasma concentrations were below limit of quantification (1 μg/mL) at 3 hours for all other subjects; no subject had measurable concentrations at the 6 and 12 hour time points. The mean (SD) Cmax, Tmax, and AUC0-12h values for benzyl alcohol were 2.737 (1.107) μg/mL, 1.42 (1.242) hours, and 19.240 μg∙h/mL, respectively.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    In an oral (diet) mouse carcinogenicity study, spinosad was administered to CD-1 mice at doses of 0.0025, 0.008, and 0.036% in the diet (approximately 3.4, 11.4, and 50.9 mg/kg/day for males and 4.2, 13.8, and 67.0 mg/kg/day for females) for 18 months. No treatment-related tumors were noted in the mouse carcinogenicity study up to the highest doses evaluated in this study of 50.9 mg/kg/day in male mice and 13.8 mg/kg/day in female mice. Female mice treated with a dose of 67.0 mg/kg/day were not evaluated in this study due to high mortality.

    In an oral (diet) rat carcinogenicity study, spinosad was administered to Fischer 344 rats at doses of 0.005, 0.02, 0.05, and 0.1% in the diet (approximately 2.4, 9.5, 24.1 and 49.4 mg/kg/day for males and 3.0, 12.0, 30.1 and 62.8 mg/kg/day for females) for 24 months. No treatment-related tumors were noted in the rat carcinogenicity study in male or female rats up to the highest doses evaluated in this study of 24.1 mg/kg/day in male rats and 30.1 mg/kg/day in female rats. Rats in the highest dose group in this study were not evaluated due to high mortality.

    Spinosad demonstrated no evidence of mutagenic or clastogenic potential based on the results of four in vitro genotoxicity tests (Ames assay, mouse lymphoma L5178Y assay, Chinese hamster ovary cell chromosome aberration assay, and rat hepatocyte unscheduled DNA synthesis assay) and one in vivo genotoxicity test (mouse bone marrow micronucleus assay).

    Oral administration of spinosad (in diet) to rats, throughout mating, gestation, parturition and lactation, demonstrated no effects on growth, fertility or reproduction, at doses up to 10 mg/kg/day [see Use In Specific Populations (8.1)].

  • 14 CLINICAL STUDIES

    14.1 Head Lice Infestations

    Two multicenter, randomized, investigator-blind, active-controlled trials were conducted in 1038 subjects 6 months of age and older with head lice infestation. A total of 552 subjects were treated with Spinosad Topical Suspension. For the evaluation of efficacy, the youngest subject from each household was considered to be the primary subject of the household, and other members in the household were enrolled in the study as secondary subjects and evaluated for all safety parameters.

    In Study 1, 91 primary subjects were randomized to Spinosad Topical Suspension, and 89 primary subjects were randomized to permethrin 1%. In Study 2, 83 and 84 primary subjects were randomized to Spinosad Topical Suspension and permethrin 1%, respectively.

    In both trials, all subjects who were treated on Day 0 returned for efficacy evaluation at Day 7. Subjects with live lice present at Day 7 received a second treatment. Subjects who were lice free on Day 7 were to return on Day 14 for evaluation. Subjects with live lice and who received a second treatment were to return on Days 14 and 21.

    Efficacy was assessed as the proportion of primary subjects who were free of live lice 14 days after the final treatment. Table 3 contains the proportion of primary subjects who were free of live lice in each of the two trials.

    14.2 Scabies Infestations

    Two multicenter, randomized, double-blind, vehicle-controlled trials (Trial 1 [NCT02485717] and Trial 2 [NCT02485704]) were conducted in subjects from 206 households in which at least one household member 4 years of age or older had an active scabies infestation. An active scabies infestation was defined as the presence of clinical signs and symptoms (evidence of burrows or presence of inflammatory/ noninflammatory lesions and pruritus) as well as microscopic evidence from a skin scraping or dermatoscopy to demonstrate the presence of mites, eggs, and/or scybala. All members of the household were treated with the same randomized treatment (Spinosad Topical Suspension or vehicle), whether or not the household member had an active scabies infestation. Subjects applied a single application of Spinosad Topical Suspension or vehicle on Day 1 and returned for evaluation on Day 28.

    The two studies enrolled 533 adult and pediatric subjects 4 years of age and older. A total of 286 subjects (212 adults and 74 pediatrics) were treated with Spinosad Topical Suspension and 247 subjects (176 adults and 71 pediatrics) were treated with vehicle. For the evaluation of efficacy, the youngest subject from each household with an active scabies infestation was considered to be the primary subject of the household, and other members in the household were enrolled in the trial as secondary subjects and evaluated for all safety parameters. In Trial 1, 43 primary subjects were randomized to Spinosad Topical Suspension, and 43 primary subjects were randomized to vehicle. In Trial 2, 62 and 58 primary subjects were randomized to Spinosad Topical Suspension and vehicle, respectively.

    Efficacy was assessed as the proportion of primary subjects who achieved complete cure 28 days after treatment. Complete cure is defined as a demonstration of clinical cure (all signs and symptoms have completely resolved, including burrows, inflammatory/non-inflammatory lesions and pruritus) and microscopic or dermatoscopic cure demonstrating the absence of mites, eggs, and/or scybala, and negative dermatoscopy for burrows. Table 4 contains the proportion of primary subjects who achieved complete cure in each of the two trials.

Ask your healthcare provider or pharmacist if you have questions about the right way to use Spinosad Topical Suspension.

    Important information:

    • Your hair and scalp must be dry before applying Spinosad Topical Suspension.
    • For very thick, medium length hair or long hair, an entire bottle (120mL) of Spinosad Topical Suspension may be needed to cover the scalp and hair. Less Spinosad Topical Suspension may be needed for shorter, thinner hair.

    How to apply Spinosad Topical Suspension to your scalp and hair:

    Step 1

    Step 1

    • Shake Spinosad Topical Suspension bottle well right before use.

    Step 2

    Step 2

    • Cover your face and eyes with a towel and keep your eyes closed tightly.
    • Apply Spinosad Topical Suspension directly to dry hair and scalp.
    • Completely cover the scalp and hair closest to the scalp first, and then apply outwards towards the ends of the hair.
    • It is important to apply enough Spinosad Topical Suspension to cover your entire scalp and hair so that all lice and eggs are exposed to Spinosad Topical Suspension.

    Step 3

    Step 3

    • Allow Spinosad Topical Suspension to stay on your scalp and hair for 10 minutes. Use a timer or clock and start timing after you have completely covered your hair and scalp with Spinosad Topical Suspension.
    • Continue to keep eyes covered to prevent dripping into your eyes.
    • After 10 minutes, completely rinse Spinosad Topical Suspension from your hair and scalp with warm water.
    • You may use a fine-tooth comb to remove treated lice and nits from the hair and scalp, but combing is not required.
    • Wash your hands after applying Spinosad Topical Suspension.
    • It is okay to shampoo your hair any time after the treatment.

    If you see live lice on your scalp or hair one week (7 days), after your first treatment, repeat the steps above.

    How do I stop the spread of lice?

    To help prevent the spread of lice from one person to another, here are some steps you can take:

    • Avoid direct head-to-head contact with anyone known to have live, crawling lice.
    • Do not share combs, brushes, hats, scarves, bandannas, ribbons, barrettes, hair bands, towels, helmets, or other hair-related personal items with anyone else, whether they have lice or not.
    • Avoid sleepovers and slumber parties during lice outbreaks. Lice can live in bedding, pillows, and carpets that have recently been used by someone with lice.
    • After finishing treatment with lice medicine, check everyone in your family for lice after one week. Be sure to talk to your healthcare provider about treatments for those who have lice.
    • Machine-wash or dry-clean any bedding, towels and clothing used by anyone having lice. Machine-wash at high temperatures (150°F) and tumble in a hot dryer for 20 minutes.
    • Wash personal items such as combs, brushes, and hair clips in hot water.
