What side effects are associated with this type of intervention?

Common treatments for scabies, such as ivermectin and permethrin, have known side effects. Ivermectin can cause side effects like headache, dizziness, muscle pain, nausea, and diarrhea. In rare cases, it may lead to more severe reactions such as hypotension and liver damage. Permethrin, a topical treatment, may cause skin irritation, redness, and itching at the application site. Both treatments are generally well-tolerated, but patients should be monitored for adverse reactions.

What prior FDA approvals exist?

The FDA has approved several antiparasitic agents for the treatment of scabies. The most commonly used treatments include permethrin cream 5%, which is a topical scabicide, and oral ivermectin, which is used off-label but has shown efficacy in treating scabies. These treatments target the scabies mites effectively. Moxidectin, another antiparasitic agent, is currently being studied for its efficacy in treating scabies, but it has not yet received FDA approval for this indication.

What other types of research exist?

Promising alternatives to Moxidectin for treating scabies include Ivermectin, which is an oral antiparasitic agent commonly used for scabies, and Permethrin, a topical treatment. Both have demonstrated efficacy and safety in treating scabies. Additionally, ongoing research may introduce new treatments, so it is advisable to consult with a healthcare provider for the latest options.

Study Summary

This trial will assess the efficacy and safety of 3 moxidectin doses for scabies in adults. Results to determine safe and effective dose.

Who is the study for?

Adults over 18 with active scabies, confirmed by clinical signs and microscopic evidence, can join this trial. Women who can have children must use effective birth control until 16 weeks after the study drug is taken. People cannot participate if they've had moxidectin recently, have trouble swallowing pills, are allergic to certain meds, abuse substances, live with untreated scabies cases or need other immune treatments.Check my eligibility

What is being tested?

The trial tests how well a single dose of Moxidectin (8 mg, 16 mg or 32 mg) works in curing scabies by Day 28 compared to a placebo. It's also looking at the safety of these doses for adults with scabies.See study design

What are the potential side effects?

Potential side effects from Moxidectin may include allergic reactions for those sensitive to similar medications; however specific side effects related to treating scabies are not detailed here.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.

Primary outcome measures

Incidence and severity of Treatment Emergent Adverse Event (Safety)

Proportion of index subjects achieving complete cure (Efficacy)

Other outcome measures

Proportion of index subjects achieving clinical cure without microscopic or dermatoscopic cure, assessed by skin examination to confirm all signs of scabies have completely resolved.

Proportion of index subjects achieving microscopic or dermatoscopic cure without clinical cure. Microscopic or dermatoscopic cure is assessed by demonstrating the absence of scabies mites, eggs, and/or scybala, and negative dermoscopy for burrows.

Moxidectin 32 mg (over encapsulated) will be administered as a single dose on Day 0.

Group III: Moxidectin 16mgExperimental Treatment1 Intervention

Moxidectin 16 mg (over encapsulated) will be administered as a single dose on Day 0. Each subject will receive the same number of capsules made up of moxidectin 2 mg over encapsulated tablets and placebo capsules to maintain the blind.

Group IV: PlaceboPlacebo Group1 Intervention

Mechanism Of Action

Side Effect Profile

Prior Approvals

Other Research

Common treatments for scabies, such as moxidectin, ivermectin, and permethrin, work by targeting the nervous system of the scabies mites, leading to paralysis and death of the parasites. Moxidectin, for example, binds to glutamate-gated chloride channels in the mites, increasing the permeability of the cell membrane to chloride ions, which results in hyperpolarization and paralysis. This mechanism is crucial for scabies patients as it directly eliminates the mites responsible for the infestation, thereby reducing symptoms like intense itching and preventing the spread of the condition to others.
