Persistent Lyme Empiric Antibiotic Study Europe (PLEASE)

September 6, 2016 updated by: Radboud University Medical Center

Persistent Lyme Empiric Antibiotic Study Europe. A Prospective, Randomised Study Comparing Two Prolonged Oral Antibiotic Strategies After Initial Intravenous Ceftriaxone Therapy for Patients With Symptoms of Proven or Possible Persistent Lyme Disease

The purpose of the study is to establish whether prolonged antibiotic treatment of patients diagnosed with proven or presumed PLD (as endorsed by the international ILADS guidelines) leads to better patient outcome than short-term treatment as endorsed by the Dutch CBO guidelines.

Study Overview

Status

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.

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.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Males or non-pregnant, non-lactating females who are 18 years or older.
  • Women of child-bearing potential must agree to use contraception methods other than oral contraceptives during the study therapy period, since failure of oral contraceptives due to long-term antibiotic use has been described and doxycycline might be teratogenic.

  • Patients with presumed or proven PLD. In this study, clinical suspicion of PLD is defined as complaints of musculoskeletal pain, arthritis or arthralgia, neuralgia or sensory disturbances (such as paresthesias or dysesthesias), neuropsychological or cognitive disorders, and persistent fatigue, that are:

    • temporally related to an episode of erythema migrans or otherwise proven symptomatic Lyme disease (defined as within 4 months after erythema migrans as assessed by a physician, or positive biopsy, PCR, culture, intrathecal B. burgdorferi antibodies), OR
    • accompanied by a positive B. burgdorferi IgG or IgM immunoblot (as defined by strict criteria in line with the European Union Concerted Action on Lyme Borreliosis (EUCALB)), regardless of prior ELISA IgG/IgM screening results.
  • Subjects must sign a written informed consent form.

Exclusion Criteria:

  • Subjects with a known history of allergy or intolerance to tetracyclines, macrolides, hydroxychloroquine or ceftriaxone.
  • Subjects who have had more than 5 days of antimicrobial therapy with activity against B. burgdorferi within the previous 4 weeks.
  • Subjects with a presumed diagnosis of neuroborreliosis (CSF pleocytosis or intrathecal antibody production) for which intravenous antimicrobial therapy is required.
  • Subjects with a known diagnosis of HIV-seropositivity or other immune disorders. (No HIV serologic testing is required for the study).
  • Subjects with positive syphilis serology or signs of other spirochetal diseases.
  • Subjects with moderate or severe liver disease defined as alkaline phosphatase, ALAT, or ASAT greater than 3 times upper limit of normal.
  • Subjects who are receiving and cannot discontinue cisapride, astemizole, terfenadine, barbiturates, phenytoin, or carbamazepine (The concentrations of these drugs may increase during clarithromycin therapy and/or lead to reduced availability of doxycycline).
  • Subjects who are currently enrolled on other investigational drug trials or receiving investigational agents.
  • Subjects who have been previously randomized into this study.
  • Severe physical or psychiatric co-morbidity that interferes with participation in the study protocol, including previous medical diagnosis of rheumatic conditions, chronic fatigue syndrome or chronic pain conditions as well as insufficient command of the Dutch language.
  • Co-morbidity that could (partially) account for the symptoms of the subject (e.g. vitamin B12 deficiency, anemia, hypothyroidism).

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
Measure Description
Time Frame
Global score 36-item Short-form General Health Survey (SF 36)
Time Frame: Week 14
Because different operationalizations of the term 'Global score 36-item Short-form General Health Survey (SF 36)' exist, the primary outcome measure is specified here as the 'physical component summary score' (PCS) of the RAND-36 Health Status Inventory (RAND SF-36, Hays 1998), which is similar to the Medical Outcomes Study (MOS) 36-item Short-Form General Health Survey (SF-36). The PCS is also known as the physical health composite score (PHC). This specification has been communicated to the local Ethics Committee on March 1, 2011, and was approved on April 6, 2011.
Week 14

Secondary Outcome Measures

Secondary Outcome Measures
