Mycosis Fungoides Clinical Trial
Official title:
A Single-center, Single-arm, Open-label Phase IIA Clinical Trial to Investigate Efficacy and Safety of Ritlecitinib (PF-06651600) in Patients With Cutaneous T Cell Lymphomas
The purpose of this research study is to evaluate the effectiveness and safety of Ritlecitinib in skin and blood in persons with Cutaneous T-Cell Lymphoma (CTCL). CTCL is a rare type of cancer that starts in the white blood cells and eventually can result in rashes or tumors in the skin. This study includes a 24 week Treatment Period and a 24 week Follow-up Period. This study will involve physical examinations, visual assessments, laboratory tests, PET-CT scans, electrocardiograms, photographs of your skin, skin biopsies, and hearing tests.

Primary | Change in Modified Severity Weighted Assessment Tool (mSWAT) | Change in Modified Severity Weighted Assessment Tool (mSWAT) at Week 24 from baseline. Skin response was primarily classified based on an assessment using mSWAT, provided there was documented evidence of stable disease or better in lymph node/viscera.The mSWAT is a tool specifically developed to evaluate the extent of skin disease in CTCL.
Responses in the skin based on SWAT are defined as: Complete Response (CR): no evidence of skin disease Partial Response (PR): = 50% decrease of the modified SWAT score compared with baseline Stable Disease (SD): Neither CR, PR, or PD as compared with baseline, i.e. change from baseline is less than a 50% decrease but also less than a 25 % increase in the modified SWAT score Progressive Disease (PD): = 25% increase in the modified SWAT score compared with baseline. |

Secondary | Absolute change of health-related quality of life (Skindex-29) | Absolute change of health-related quality of life (Skindex-29 - questionnaire regarding skin conditions) from Baseline up to Week 48.
Skindex29 is a 30 question survey that measures quality of life. It is scored from 1-Never to 5-All the time. Full scale from 30-150. The lower the score, the better the quality of life. |

The FACT-G is comprised of four subscales: physical well-being (7-items, score range 0-28), social/family well-being (7-items, score range 0-28), emotional well-being (6-items, score range 0-24), and functional well-being (7-items, score range 0-28). All questions in the FACT-G use a 5-point rating scale (0 = Not at all; 1 = A little bit; 2 = Somewhat; 3 = Quite a bit; and 4 = Very much). Full scale scored from 0-108. The higher the score, the better the quality of life. |
Baseline and at each visit from week 2 to week 48 / EOS | |
Secondary | Absolute change of IPQ-R (Illness perception questionnaire) | Absolute change of IPQ-R (Illness perception questionnaire) from Baseline up to Week 48.
The IPQ-R an 70-item instrument developed to provide a quantitative measurement of the components of illness representations. It is divided into three sections: identity subscale (14 symptoms scored as 1-yes or 0-no, subscale from 0-14), views about illness (38 questions scored between 5-strongly agree to 1-strongly disagree, subscale from 38-190) and a third section regarding views on possible causes (18 causes scored between 5-strongly agree to 1-strongly disagree, subscale from 18-90). Full scale from 56-294. High scores on the identity and views of illness sections represent strongly held beliefs about the number of symptoms attributed, the negative consequences, and the chronicity and cyclical nature of the illness. High scores in the section regarding causes represent positive beliefs about controllability and a personal understanding of the illness. |
Baseline and at each visit from week 2 to week 48 / EOS | |
Secondary | Percentage change of pruritus according to visual analogue scale (VAS) | Percentage change of pruritus according to visual analogue scale (VAS). Line graph to collect information about general itch level as well as worst itch level in the past 24 hours on a scale of 0 to 10, with higher score indicating more itch from baseline up to week 48. | Baseline and at each visit from week 2 to week 48 / EOS |
