Study summary

This is a multi-center, double-blind, randomized, two arm parallel design study. This study is comprised of two phases: screening and treatment. The screening period will be up to 5 days, followed by the treatment phase of 28±4 days. During the treatment phase subjects will be randomized to receive either test or reference treatments in a double-blind manner in an outpatient setting. Randomization of subjects will be in a 1:1 ratio for the test and reference drug arms and will be stratified by site.

Screening will begin at visit 1, during which eligibility will be determined and prohibited treatments will be discontinued. Randomization will occur following the confirmation of the eligibility criteria at visit 2 (baseline, Day 1) i.e. initiation of treatment phase. The treatment phase will be 28±4 days in duration wherein subject will receive treatment with investigational product (either test or reference) on Day 1 or Baseline (visit 2). Safety and tolerability assessments will be performed on Day 7 (visit 3). Efficacy, safety and tolerability will be assessed on Day 14 (visit 4) followed by the End of study visit on Day 28 (visit 5). If positive identification of scabies is confirmed at Day 14 (visit 4), the subject will be retreated with the second application of the investigational product.

Read the detailed description

Systemic absorption of permethrin cream is limited to 0.5% during the first 48 hours following dermal application. In these settings, a conventional pharmacokinetic human study to demonstrate that Mayne Permethrin cream (5% w/w) is bioequivalent to the Reference Listed Drug [RLD] Elimite™ is not appropriate.

This is a clinical endpoint bioequivalence (BE) study for a Permethrin Cream, 5% formulation for the treatment of active scabies in comparison to Elimite™ Permethrin cream (5% w/w).

  • Test Product: Permethrin Cream, 5%
  • Reference Product: Elimite™ marketed by Prestium Pharma, Inc. ("Prestium"), the branded subsidiary of Renaissance Pharma.

The infested person, as well as household members are treated at the same time to prevent re-infestation. In consideration of this recommendation, the household members of the enrolled subject will be examined and treated at the same time as the enrolled subject with an FDA-approved generic Permethrin Cream, 5%.

Inclusion criteria

  1. Male or non-pregnant, non-lactating female subject at least 12 years of age or older.
  2. Subject must have a positive identification for mites, eggs, or mite fecal matter by microscopic examination of a skin scraping.
  3. Subjects must have at least two of the three following: a) excoriations and inflammatory papules with a typical distribution pattern and localization (webbed spaces of the fingers, flexor surfaces of the wrists, elbows, axillae, belt line, feet, skin surface of external genitalia, or areolae); b) presence of burrows; c) family or contacts with moderate to severe itching which increases during the night.
  4. Subjects must be willing to make every effort to immediately disinfect clothes, towels, and linens and all potentially infected household items upon diagnosis of infestation to prevent re-infestation.
  5. All household members with prolonged physical contact with the subject must be willing to attend Baseline visit and receive treatment with standard of care if deemed necessary by the Investigator in order to prevent re-infestation of the subject enrolled.
  6. Subject or representative must read and sign an Institutional Review Board/Independent Ethics Committee (IRB/IEC) approved Form (ICF); for minor subjects (18 years or younger in most states) the parent or legal guardian should sign the ICF and the child will be required to sign the Assent Form that will written in such a way as to be understandable to a child.
  7. Subject must be able to apply study product to self. If the subject is a child, then parent/guardian will apply study product to him/her.

Exclusion criteria

Exclusion Criteria:

  1. Females who are pregnant as shown in a urine pregnancy test at the Baseline visit, prior to randomization, or lactating, or of (for purpose of this study a female of childbearing potential is considered to be not surgically sterile or for at least 1 year) who are not using or do not agree to use an acceptable form of (oral /implant /injectable /transdermal contraceptives, intrauterine device (IUD), condom, diaphragm, or abstinence) during the study, or who intends to become pregnant during the study; contraceptive method must also be consistent throughout the study.
  2. Treatment for scabies \<4 weeks prior to enrollment, including permethrin, benzyl alcohol, lindane, crotamiton, malathion, and ivermectin.
  3. Use of prohibited medications:

    • Topical or oral scabicidal/antiparasitic treatment including: permethrin, benzyl alcohol, benzyl benzoate, lindane, crotamiton, malathion, ivermectin, precipitated sulfur, albendazole, keratolytic cream, tea tree oil, or oil of the leaves of Lippia multiflora Moldenke within 28 days of visit 2.
    • Systemic (including inhaled steroids) taken within 14 days of visit 2.
    • Topical corticosteroids including hydrocortisone taken within 24 hours of visit 2.
    • Topical antipruritics, including antihistamines within 24 hours of any study visits.
    • Oral antihistamine including diphenhydramine (Benadryl) taken within 24 hours of any study visits.
    • Topical antibiotics including mupirocin taken within 24 hours of any study visits.
  4. Patients with disorders requiring therapy, severe systemic disease, history of infection and/or seizures.
  5. Patients with crusted/Norwegian scabies.

Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
