  3. Systemic therapy for CTCL is indicated.
  4. A Karnofsky performance score ≥60%.
  5. Age ≥18 years.

Sexual abstinence or effective contraception must be used for at least 1 month prior to the initiation of therapy, during therapy, and for at least 1 month following discontinuation of therapy. Perimenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.

What researchers measure

Primary outcomes

  1. Number of Participants With Tumor Response (Complete Response [CR], Clinical Complete Response [CCR], and Partial Response [PR]) in up to 5 Index Lesions as Determined by Investigator's Composite Assessment (CA) of Index Lesion Disease Severity

    Index lesion symptoms/grade include: erythema=0 (no evidence)-8 (very severe); scaling=0 (no evidence)-8 (very severe); plaque elevation=0 (no evidence)-8 (extreme elevation); hypopigmentation/hyperpigmentation=0 (no evidence of change)-8 (very severe change); area of involvement=0 (0 centimeters \[cm\]\^2)-18 (\>300 cm\^2). CA generated by sum of grades of signs/symptoms for each index lesion. Index lesion CA grade at baseline was divided into CA grade at each subsequent study visit to determine participant's response to treatment. Ratio of CA \<1.0=improvement in disease; ratio \>1.0=worsening of disease. Tumor response as determined by CA=percentage of participants achieving CR (CA ratio=0, no clinically abnormal lymph nodes, and absence of histologic signs of CTCL); CCR (CA ratio=0 and no clinically abnormal lymph nodes); and PR (CA ratio=≤0.5, \<25% increase in number/aggregate area of abnormal lymph nodes/tumors, and no new abnormal lymph nodes in documented area of absence of disease).

    Time frame: Baseline up to Week 24

  2. Number of Participants With Tumor Response of CR, CCR, PR, SD, and PD as Determined by Physician's Global Assessment (PGA) of Clinical Condition

    The PGA was an assessment of the overall extent of improvement/worsening from Baseline of the participant's overall disease compared with the condition every 4 weeks thereafter during treatment. CR=PGA grade of 0 (completely clear of disease since Baseline) and absence of histologic signs of CTCL. CCR=PGA grade of 0. PR=PGA grade of 1 (almost clear \[≥90%-\<100%\] of disease since Baseline), 2 (marked improvement \[≥75%-\<90%\] of disease since Baseline), 3 (moderate improvement \[≥50%-\<70%\] of disease since Baseline). Stable Disease (SD)=PGA grade of 4 (slight improvement \[\<25%-\<50%\] of disease since Baseline) or 5 (no change in disease \[+/-\<25% change since Baseline\]). Progressive Disease (PD)=PGA grade of 6 (worse disease \[≥25%\] than at baseline). If visceral disease or an abnormal lymph node was located in a documented area of absence of disease, then PD would be reported for the participant.

    Time frame: Baseline up to Week 24

  3. Number of Participants With Tumor Response of CR, CCR, PR, SD, and PD as Determined Percent Body Surface Area (BSA) Involvement

    To determine BSA involvement, the area of the participant's palm was defined as 1% of the participant's BSA. The extent of involvement of disease was determined as multiples of the participant's palm area and expressed as a percentage of the participant's total BSA at Baseline (Day 1) and every 4 weeks thereafter during treatment. CR=percent BSA 0% and documented absence of histologic signs of CTCL. CCR=Percent BSA 0%. PR=a decrease from Baseline in percent BSA of at least 50%. SD=none of the response classifications (that is, CR, CCR, PR, or PD) accurately describe the disease status. PD=an increase from Baseline in percent BSA of at least 25%.

    Time frame: Baseline up to Week 24

Defined as time interval from first day of bexarotene treatment to time of first observation when participant met the criteria of CR, CCR, or PR. PGA was an assessment of the overall extent of improvement/worsening from Baseline of the participant's overall disease compared with the condition every 4 weeks thereafter during treatment. CR=PGA grade of 0 (completely clear of disease since Baseline) and absence of histologic signs of CTCL. CCR=PGA grade of 0. PR=PGA grade of 1 (almost clear \[≥90%-\<100%\] of disease since Baseline), 2 (marked improvement \[≥75%-\<90%\] of disease since Baseline), 3 (moderate improvement \[≥50%-\<70%\] of disease since Baseline).

SecondaryTime to Tumor Response (CR, CCR, or PR) as Determined by Percent BSA Involvement

Defined as time interval from first day of bexarotene treatment to time of first observation when participant met the criteria of CR, CCR, or PR. To determine BSA, the area of the participant's palm was defined as 1% of the participant's BSA. The extent of involvement of disease was determined as multiples of the participant's palm area and expressed as a percentage of the participant's total BSA at Baseline (Day 1) and every 4 weeks thereafter during treatment. CR=percent BSA 0% and documented absence of histologic signs of CTCL. CCR=Percent BSA 0%. PR=a decrease from Baseline in percent BSA of at least 50%.

SecondaryTime to Tumor Progression as Determined by CA of Index Lesion Disease Severity

Defined as time interval from first day of bexarotene treatment to time of first observation when participant met criteria for PD. Index lesion symptoms/grade: erythema/scaling=0 (no evidence)-8 (very severe); plaque elevation=0 (no evidence)-8 (extreme elevation); hypopigmentation/hyperpigmentation=0 (no evidence)-8 (very severe change); and area of involvement=0 (0 cm\^2)-18 (\>300 cm\^2). CA: sum of signs/symptoms grades for index lesion. Index lesion CA grade at baseline divided into CA grade at study visit to determine treatment response. CA Ratio \<1.0=improvement and \>1.0=worsening of disease. Criteria for PD requires at least 1 component of the following: CA ratio=≥1.25, ≥25% increase in number/aggregate area of abnormal lymph nodes/tumors, or no new abnormal lymph nodes in documented area of absence of disease.

SecondaryTime to Tumor Progression as Determined by PGA of Clinical Condition

Defined as time interval from first day of bexarotene treatment to time of first observation when participant met criteria for PD. PGA was an assessment of the overall extent of improvement/worsening from Baseline of the participant's overall disease compared with the condition every 4 weeks thereafter during treatment. PD=PGA grade of 6 (worse disease \[≥25%\] than at baseline). If visceral disease or an abnormal lymph node was located in a documented area of absence of disease, then PD would be reported for the participant.

The extent of involvement of disease was determined as multiples of the participant's palm area and expressed as a percentage of the participant's total BSA at Baseline (Day 1) and every 4 weeks thereafter during treatment.
