About this study

Official title: A Single Treatment Pharmacokinetic and Safety Study of Natroba (Spinosad) Topical Suspension 0.9% w/w in Subjects 1 Month to 3 Years 11 Months of Age With an Active Scabies Infestation

A population of approximately 50 pediatric subjects will be enrolled to assess the PK of spinosad and benzyl alcohol for 3 hours following a single, full-body topical application (open label) on a single in-clinic visit (Day 1, or Day 2 if screening only on Day 1). There will be approximately 50 subjects ages 1 month to 3 years 11 months of age enrolled with the goal of completing approximately 16 subjects. With assistance from a caregiver, Natroba will be applied over the entire body from the neck down to the toes (including the soles of the feet) and to the hairline, temples, forehead and possibly the scalp (if a scabies infestation is present on the scalp). The open-label Investigational Product (IP) will remain on the skin for at least 6 hours before removing the IP by gentle washing. The subjects will stay in the clinic until the 3-hour procedures are completed. Blood draws will be taken at 0 hours just prior to treatment, and then at 0.5 and 3.0 hours post-treatment. Heel sticks are likely to be the mode of blood collection for children less than 2 years of age. A ±5-minute time window will be allowed for all post-treatment blood samples. Removal of IP can occur by the caregiver at home after it has been on the skin for at least 6 hours before bathing the child. Safety will be assessed with adverse events (AEs), general skin and eye irritation assessments, and pre-dose and pre-discharge laboratory evaluations. Following the sample collections subjects will be released from the clinic and directed to their primary care physician for follow-up. Subjects will be provided scabies medications upon discharge to dispense to family members. These include 5% Permethrin for those in the household that are less than 4 years of age and Natroba for those in the household 4 years of age and older. Subjects who terminate early will not be given these medications to dispense to family members.

Natroba (spinosad) Topical Suspension, 0.9% w/w applied by a parent/guardian in a single, full-body topical application from the neck down to the toes (including the soles of the feet) and to the hairline, temples, forehead and possibly the scalp (if a scabies infestation is present on the scalp).

A blood draw will be taken from subjects just before spinosad application (t=0) and then at 0.5 and3.0 hours. The following PK parameters will be calculated for spinosad (spinosyn A and spinosyn D) and benzyl alcohol in each subject: Cmax, Tmax, and Area Under the Curve (AUC) 0-12h.

Safety assessments include monitoring of AEs on study Day 1 or Day 2, general skin and eye irritation assessment on Day 1 or Day 2, laboratory assessments on Day 1 or Day 2, prior medications, and concomitant medications on Day 1 (and Day 2, if applicable). Smaller laboratory blood samples will be collected pre-dose and 12-hours post-dose prior to discharge.

Pharmacokinetic (PK) parameters will be calculated by using model independent methods. Standard statistical analyses will be done on these parameters for the purpose of interpretation of the data (Cmax, Tmax and Area Under the Curve (AUC) 0-3h and will be used to assess the absorption over 3 hours post-administration in 50 subjects (1 month - 3 years 11 months). The PK parameter estimates will be computed with noncompartmental methods for each subject. Individual elapsed sampling times (actual time) will be used in the PK analysis and parameters will be computed for each subject. Descriptive summaries of the plasma concentration levels for both spinosad (spinosyn A and spinosyn D) and benzyl alcohol observed at each nominal time point will be provided. Descriptive summaries of the PK parameter estimates will also be completed. Summary statistics for continuous variables will include number of non-missing observations, mean, standard deviation, coefficient of variation (CV%), median, minimum, and maximum, geometric mean and standard error of the geometric mean.

The safety endpoints include the evaluation of adverse events, general skin and eye irritation assessments, clinical laboratory assessments, and use of prior medications and concomitant medications. Additionally, the descriptive changes from baseline (pre-dose) to final assessment (pre-discharge) will be calculated for applicable parameters.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Spinosad Topical in people with Scabies, run by Cipher Pharmaceuticals Inc. at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sharda Angl (905-602-5840 ext. 267, sangl@cipherpharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmax for Spinosyn A (time frame: Blood samples collected up to 3 hours post treatment - 0 (pre-treatment), 0.5 and 3.0 hours post-treatment.). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Feb 2025.
