Brief Summary:

This multi-center, double-blind, vehicle-controlled, randomized crossover design study will evaluate the safety and efficacy of topically applied naloxone lotion, 0.5%, for the treatment of pruritus in patients with the mycosis fungoides (MF) or Sézary syndrome (SS) Forms of Cutaneous T-cell Lymphoma (CTCL). This study will also determine if there is systemic absorption of the drug in a subset of subjects and if so, describe the range and mean plasma levels reached after two weeks of three time daily (TID) dosing.

Funding Source - FDA OOPD

Condition or disease Intervention/treatment Phase
Mycosis Fungoides Lymphoma, T-Cell, Cutaneous Sézary Syndrome Drug: Naloxone Hydrochloride Lotion, 0.5% Drug: Placebo Lotion Phase 3

Detailed Description:
There will be 160 subjects enrolled in the study. The study consists of a Screening Period of up to 7 days during which inclusion / exclusion criteria will be reviewed. Subjects meeting inclusion / exclusion criteria including the diagnostic criteria for MF or SS and a score of at least 5 on the 11-Point Numeric Rating Scale (NRS) for Pruritus will complete the one week Screening Period. Subjects will complete a daily diary for NRS for Pruritus scores and Sleep scores. At the end of the Screening Period, subjects who have a NRS for Pruritus score of at least 5 recorded in the diary on at least 4 of the 7 days preceding Day 0 will be eligible to continue. Baseline assessments will be recorded for vital signs, pruritic body surface area, skin integrity, PQOL, and laboratory results. The Baseline period will be followed by a 2 week Treatment Period 1 in which subjects will be randomized to Naloxone Lotion 0.5% or Placebo Lotion to be applied TID for 14 days. During the 2 week Treatment Period subjects will complete daily diaries of NRS for Pruritis scores and Sleep scores. On Day 14 subjects will return to the clinic to review diaries, adverse events (AEs), concomitant medications, and to record body surface area for pruritus, skin integrity, PQOL, and laboratory results. Subjects will then enter a Washout Period for up to 56 days until the subject again scores at least 5 on the NRS for Pruritus on 4 consecutive or 4 of the past 7 days or 56 days pass. Subjects will then enter a 2 week Treatment Period 2 during which the same procedures as Treatment Period 1 will be performed except subjects will receive the alternate treatment to that assigned in Treatment Period 1.

Primary Outcome Measures :
  1. Numeric Rating Scale (NRS) for Pruritus [ Time Frame: Baseline and 2 Weeks ]
    Change from Baseline to Day 14 in average NRS for Pruritus for each Treatment Period

Secondary Outcome Measures :
  1. Responder Analysis - The difference in the proportion of subjects with a meaningful clinically significant improvement at the end of the two periods. [ Time Frame: Baseline and 2 Weeks ]
    The difference in the proportion of subjects with a meaningful clinically significant improvement at the end of the two periods. A clinically significant improvement is defined as an improvement of at least one category on the 4-point (none, mild, moderate, severe) Likert Scale verbal rating scale (VRS) and at least two points on the 11-point NRS for Pruritus. The NRS for Pruritus scores will be converted to VRS scores as follows for the analysis: 0=none, 1-3=mild, 4-6=moderate, and 7-10=severe.

  2. Numeric Rating Scale for Sleep [ Time Frame: Baseline and 1 and 2 weeks ]
    The change from Baseline at each week of the NRS for Sleep average score for each Treatment Period.

  3. Numeric Rating Scale for Pruritus [ Time Frame: Baseline and 1 week ]
    The change from Baseline at Week 1 of the NRS for Pruritus average score for each Treatment Period.

  4. Categorical Rating Scale (CRS) for Skin Integrity [ Time Frame: Baseline and 2 weeks ]
    The change from Baseline at Week 2 of the CRS for Skin Integrity for each Treatment Period.

  5. Pruritus Quality of Life Score (PQOL) [ Time Frame: Baseline and Day 14 of each Treatment period ]
    The change from Baseline in the final categorization of the PQOL at Day 14 of each Treatment Period

Layout table for eligibility information
Ages Eligible for Study:   21 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

All subjects must meet the following criteria for admission into the study:

  1. Signed informed consent has been obtained.
  2. Subject is at least 21 years of age.
  3. Diagnosis of mycosis fungoides (MF) or Sézary syndrome (SS) will be based on a combination of histological, clinical, and immunophenotypical criteria. The histological criteria will be based on skin biopsy from the most representative skin area. The diagnostic criteria used for each subject will be specified in the case report forms and the specific classification of MF or SS will be identified. The TNMB system will be used to classify the stage of disease (See Section 8.4 for details).
  4. Completion of the mSWAT assessment.
  5. A history of pruritus that meets following criteria:

    At Screening Day -7:

    • present on a daily basis for greater than one month prior to Screening Day -7,
    • NRS for Pruritus score ≥5 as rated by the subject at the Day -7 Visit. Note: If the score is <5 and subject is taking or has taken a medication which may be affecting pruritus (e.g. systemic antihistamine or topical steroid), and if Investigator and subject agree, subject may washout or continue washout of medication and return for Day -7 Visit procedures after washout.

    At Baseline Period 1 Day 0:

    • NRS for Pruritus score of at least 5 recorded in the subject diary on at least 4 of the 7 days preceding Baseline Period 1 Day 0.
  6. Pruritic treatment area of 5-95% of the subject's total treatable body surface area.
  7. Subject can be expected to reliably follow treatment instructions and visit schedule.
  8. Non-pregnant, non-lactating females of childbearing potential who agree to use medically acceptable forms of birth control (abstinence, hormonal contraceptives, diaphragm with spermicide, condom with spermicide, or intrauterine device) throughout the study or females of non-childbearing potential (surgically sterile [hysterectomy or bilateral tubal ligation] or post-menopausal ≥ 1 year). A negative urine pregnancy test must be confirmed at Baseline screening for all female subjects who are not post-menopausal > 1 year or surgically sterile.
  9. The subject agrees not to begin any new concomitant medications during their participation in the study, with the exception of medications necessary to treat infection, and to continue any concomitant medication throughout the study.
  10. Subject has no visual or motor impairments that will make it difficult to complete the Daily Diary or apply the study medication.
  11. Subject is able to speak, read, and write English and agrees to participate and comply with the study procedures.
  12. Subject has a body mass index (BMI) between 18.5 and 30.5 kglm2 (see Appendix C, Body Mass Index Table) (subjects in PK subset only).

  3. Myocardial infarction within the past six months.
  4. A history of ventricular arrhythmia requiring treatment.
  5. Any medical condition which would, in the Investigator's opinion, preclude the subject from successfully participating in the study.
  6. A known allergy to naloxone hydrochloride or any excipient in the formulation.
  7. Previous naloxone use for pruritus.
  8. Positive urine drug screen at Day 0 for opiates. Positive urine drug screen for anything other than opiates not explained, e.g., by concomitant medication, would also exclude the subject.
