Recruit Status: Completed
Study Type: Interventional

Official Title: A Phase 2, Single-arm, Open-label, Multicenter Study of the Histone Deacetylase Inhibitor (HDACi) JNJ-26481585 in Subjects With Previously Treated Stage Ib-IVa Cutaneous T-cell L

Brief Summary: The purpose of this study is to determine the overall cutaneous response rate (participants who achieve a complete response or partial response) based on the modified severity weighted assessment tool criteria.

Detailed Summary: This is a single-arm (group), open-label (all people know the identity of the intervention), and multicenter study. The study consists of 3 phases including, the screening phase (within 28 days prior to the start of study medication), treatment phase (participants will receive quisinostat) and follow-up phase (30 days after the last dose of study medication until death or clinical cutoff). Clinical cut-off is defined as when the last participant will be assessed with progressive disease or died, or 6 months after the last participant enrolled, whichever occurs first. However, if any participants are still receiving study treatment at the time of clinical cut-off, these participants will enter a long-term extension phase and will continue to receive study medication until a reason for discontinuation is met (ie, disease progression, toxicity, availability of other effective medications that the participant may receive, or treating physician advice). The long-term extension phase will continue for a maximum of 2 years beyond the clinical cut-off for primary analysis. Safety will be evaluated by the assessment of adverse events, vital signs, physical examination, 12-lead electrocardiogram, and clinical laboratory tests which will be monitored in this study. Any participants responding to treatment at the end of the 2-year long-term extension phase will be able to continue to receive quisinostat as long as they are assessed by the investigator as not meeting treatment discontinuation criteria; during this time, only information related to serious adverse events will be collected.

Current Primary Outcome: Number of participants who will achieve overall cutaneous Response Rate (RR) based on modified Severity Weighted Assessment Tool (mSWAT) criteria [ Time Frame: From screening until progressive disease or confirmed lost to follow-up or death or start of alternate therapy, or withdrawal from the study; as assessed for approximately 6 months after the enrollment of the last participant ]

Original Primary Outcome: To determine overall cutaneous response (RR) rate, based on modified Severity Weighted Assessment Tool (mSWAT) criteria [ Time Frame: Up to two years ]

Current Secondary Outcome:

• Number of participants who will achieve global Response Rate (RR) based on based on consensus global response score [ Time Frame: From screening until progressive disease or confirmed lost to follow-up or death from any cause or start of alternate therapy, or withdrawal from the study; as assessed for approximately 6 months after the enrollment of the last participant ]
  The RR is defined as the number of participants who will achieve a complete response (CR) or partial response (PR). Global response score provides uniformity in the assessment of response and utilizes all component of the tumor-node-metastasis-blood staging (ie, skin, nodes, viscera and blood). Complete response is defined as complete disappearance of all clinical evidence of disease (all categories have CR/ non-involved [NI]) and PR is defined as regression of measurable disease (all categories do not have a CR/NI and no category has a PD and if any other category involved at baseline, at least one has a CR or PR).
• Progression-Free Survival (PFS) [ Time Frame: From the date of administration of the first dose of study medication until progressive disease or death from any cause, whichever occurs first; as assessed for approximately 6 months after the enrollment of the last participant ]
  PFS is defined as the interval between the date of administration of the first dose of study medication and the date of disease progression or death from any cause, whichever occurs first.
• Kaplan-Meier Estimates of 1-year overall survival (OS) rate [ Time Frame: From the date of administration of the first dose of study medication up to the date of progressive disease or death, whichever occurs first; as assessed up to 1 year ]
  1-year OS rate is defined as the number of participants surviving at 1 year after the date of administration of the first dose of study medication.
• Duration of response (DOR) for participants achieving Complete Response (CR) or Partial Response (PR) [ Time Frame: First documentation of CR or PR until the date of first documentation of progressive disease, or death from any cause; as assessed for approximately 6 months after the enrollment of the last participant ]
  DOR for participants achieving a CR or PR is defined as the date from the first documentation of CR or PR until the date of first documentation of progressive disease, or death from any cause.
• The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) [ Time Frame: From screening until progressive disease or confirmed lost to follow-up or death from any cause or start of alternate therapy, or withdrawal from the study; as assessed for approximately 6 months after the enrollment of the last participant ]
  EORTC QLQ-C30 is a questionnaire to assess quality of life of cancer patients. It is composed of 30 items, multi-item measure (28 items) and 2 single-item measures. For the multiple item measure, 4-point scale is used and the score for each item range from "1 = not at all" to "4 = very much". Higher scores indicate worsening. The 2 single-item measure involves question about the overall health and overall quality of life which will be rated on a 7-point scale ranging from "1 = very poor" to "7 = excellent". Lower scores indicate worsening.
• Pruritus Intensity Assessment Questionnaire scale scores [ Time Frame: From screening until progressive disease or confirmed lost to follow-up or death from any cause or start of alternate therapy, or withdrawal from the study; as assessed for approximately 6 months after the enrollment of the last participant ]
  Pruritus Intensity Assessment Questionnaire is an 11-point scale that requires the participant to rate the intensity of their pruritus. The scores range from '0= no pruritus; 10 = worst imaginable'. Pruritus relief will be defined as a 3 or more point decrease in participant who have a baseline pruritus score of 3 or more points or complete resolution of pruritus for 3 or more continuous weeks without an increase in the use of antipruritic medications. Higher score indicates worsening.
• Number of participants with adverse events [ Time Frame: Up to 2 years after 6 months enrollment of the last participant ]

Original Secondary Outcome:

• To determine overall global RR based on consensus global response score for mycosis fungoides (MF) / Sézary Syndrome (SS) (mSWAT + nodes/viscera + blood) [ Time Frame: Up to two years ]
• To evaluate adverse events [ Time Frame: Up to two years ]
• To determine the duration of response (DOR) [ Time Frame: First documentation of CR or PR until the date of first documentation of progressive disease (PD), or death ]
  The DOR for subjects achieving a CR or PR, defined as the date from the first documentation of CR or PR until the date of first documentation of progressive disease (PD), or death from any cause.
• To estimate progression-free survival (PFS) [ Time Frame: First dose of study drug and the date of disease progression or death ]
  The PFS, defined as the interval between the date of administration of the first dose of study drug and the date of disease progression or death from any cause, whichever occurs first
• To estimate 1-year overall survival (OS) rate [ Time Frame: First dose of study drug until death (up to 2 years) ]
  The Kaplan-Meier estimate of the proportion of subjects surviving at 1 year after the date of administration of the first dose of study drug
• To assess pharmacodynamic markers of JNJ-26481585 activity in tumor biopsies and surrogate tissues
• To explore biomarkers predictive of response to JNJ-26481585
• To explore the population pharmacokinetics (PK) of JNJ-26481585
• The European Organization for Research and Treatment (EORTC QLQ-C30) and the Pruritus Intensity Assessment Questionnaire scale scores
  The EORTC QLQ-C30 is the basic module with 30-items with appended other modules.The questionnaire includes nine multi-item scales: five functional scales (physical, role, cognitive, emotional, and social); three symptom scales (fatigue, nausea and vomiting, pain); and a global health and quality of life scale. Other single item measures are also included (dyspnea, sleep disturbance, appetite loss, constipation, diarrhea and financial impact). The instrument contains 28 items using a Likert scale with 4 response options; 'Not at All,' 'A Little,' 'Quite a Bit,' to 'Very Much' (scored 1 to 4).
