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

Objectives

Objective is to evaluate the efficacy of doxycycline in treatment of early stages of mycosis fungoides (IA, IB and IIA) and to assess its apoptotic enhancing effect by studying the expression of BCL2 by the T lymphocytes.

Study Design

Randomized controlled trial

Population of study & disease condition

30 patients with early stage mycosis fungoides (Stage Ia,Ib and IIa)

Methodology in details

After signing an informed consent, each participant will be subjected to:

I. Baseline evaluation:

  1. Baseline biopsy to document the current state of the disease and to assess immunohistochemically the expression of CD3 and Bcl2 by the lymphocytes.
  2. Detailed history taking including onset, course, duration of the disease and history of any previous treatments used.

  3. Detailed examination of skin lesions and scoring using:

    • Modified Severity of Index Weighted Assessment (mSWAT)
    • Composite Assessment of Index Lesion Severity (CAILS)
  4. Pruritus scoring using a visual analog scale from 0-10, where 0=no pruritus and 10=worst imaginable pruritus
  5. Photography

II. Treatment and dosing protocol:

Participants will be randomly allocated in either one of the treatment groups:

Group A: Will receive oral doxycycline in a dose of 200 mg daily for three months.

Group B: Will receive PUVA with dosing & increments according to the standard protocols of the Phototherapy Unit, Dermatology Department, Cairo University; 3 sessions per week for 3 months.

III. Timings of follow up visits and clinical assessments done:

Patients will be regularly assessed at weeks 4, 8, and 12. Patients continuing for another three months, as mentioned above, will be assessed at weeks 16, 20 and 24. The following will be done at these follow up visits: mSWAT, CAILS, pruritus scoring and photography. Side effects will be monitored and managed accordingly.

IV. Follow up biopsies:

A repeat biopsy will be taken at initial improvement in CAILS (or at week 12) for immunohistochemical re-assessment of the expression of CD3 and Bcl2 by the lymphocytes.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Adults (above 18) of either sex with established diagnosis of classic MF

Exclusion Criteria:

  • Any variant of MF other than the classic variant.
  • Advanced stages of classic MF: Stage IIb, III or IV.
  • Pregnant and lactating females.
  • Patients with autoimmune diseases e.g. SLE
  • Patients with solid or hematological malignancies e.g. breast cancer, leukemia, etc.
  • Patients with any contraindications for doxycycline (eg: liver disease, kidney disease, photosensitivity, peptic ulcer or patients receiving systemic retinoids).

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.

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.
