Eval 3-Drug Therapy Diethylcarbamize, Albendazole and Ivermectin That Could Accelerate LF Elimination Outside of Africa

October 5, 2018 updated by: Christopher L. King, MD, PhD, University Hospitals Cleveland Medical Center

Evaluate Triple-Drug Therapy With Diethylcarbamize (DEC), Albendazole (ALB) and Ivermectin (IVM) That Could Accelerate LF Elimination Outside of Africa

This study will determine if a combination of 3 drugs used to treat the infection that cause lymphatic filariasis (LF) due to Wuchereria bancrofti infection are more effective in killing or sterilizing the adult worms compared to just 2 of the 3 drugs that usually given to treat this infection. The three drugs used together are called albendazole (ALB), ivermectin (IVM) and diethylcarbamazine (DEC). The usual treatment in Papua New Guinea (PNG) for lymphatic filariasis are DEC and ALB. A combination of these 3 drugs has not been previously used to treat LF.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will determine whether a single dose of the triple drug regimen of DEC/Iver/Alb is non-inferior to annual treatments with DEC/Alb in inducing sustained clearance of Mf in LF infected subjects (>50 Mf/ml) at 36 months post-treatment. This study also tests the hypothesis that single dose of triple drug is super in sustained clearance of microfilariae compared to single dose of DEC/ALB.

There will be 3 treatment arms as follows:

  1. The comparator (standard treatment) DEC 6 mg/kg + Alb 400 mg administered annually (at 0, 12, and 24 months).
  2. DEC 6 mg/kg + Alb 400 mg given once
  3. DEC 6 mg/kg + Alb 400 mg + Iver 200 µg/kg administered once only at the beginning of the RCT (0 month).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Percentage of subjects with total clearance of in Wuchereria bancrofti (Wb) microfilaria (mf)
Time Frame: at 36 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
