简要总结
This is a single-arm, non-randomized feasibility study designed to find out if the laser light-based imaging test called Biodynamic imaging (BDI) can correctly predict the cutaneous T-cell lymphoma mycosis fungoides (MF) cancer response to chemotherapy treatment. The primary objective is to develop phenotypic profiles of response and non-response to gemcitabine, given at a standard-of-care dose and schedule. A secondary objective is to perform a cross-species analysis of phenotypic responses of human and canine mycosis fungoides to gemcitabine using biodynamic imaging. The study will seek to enroll 10 patients with MF who are planning to receive treatment with gemcitabine given at a standard-of-care (SOC) dose and schedule at Indiana University Simon Cancer Center (IUSCC). All subjects will undergo standardized staging tests, with tumor stage defined according to established guidelines. For the study, three 6-mm x 4-mm dermal punch biopsies from one or more target lesions will be collected prior to treatment initiation and sent to Purdue University researchers for BDI. Objective response for tumor samples treated with gemcitabine in the laboratory will be assessed. Patients with an objective response of complete response (CR) or partial response (PR) that persists during the first 2 treatment cycles will be considered to have responsive cancers, while those failing to meet these criteria will be considered to have resistant cancers. All patients will be considered off-study after completing cycle 2. Accrual is expected to last approximately 24 months.
详细描述
The purpose of this study is to find out if the laser light-based imaging test called Biodynamic imaging (BDI) can correctly predict the response of cutaneous T-cell lymphoma mycosis fungoides cancer to gemcitabine chemotherapy treatment. No untested medications or devices will be used in this study. Subject's response to chemotherapy will be measured after the first and second months (cycles) of chemotherapy; therefore, the BDI test cannot be used to predict whether subject will respond to the treatment or not in advance, and treatment decisions will not be made using any of the information obtained through this study.
As part of routine treatment for mycosis fungoides, subjects who are being referred for routine treatment with gemcitabine chemotherapy given at a standard-of-care (SOC) dose and schedule at the Indiana University Simon Cancer Center (IUSCC) will be enrolled. Standard-of-care Gemcitabine is given intravenously (i.e. in the vein as in infusion) 3 times every 28 days on days 1, 8, and 15. Each 28 day period is called a cycle. Gemcitabine infusion generally lasts 30 minutes. If subject agrees to participate in this study, researchers would document representative skin lesions by color photography including a ruler to estimate the size of the lesion, and objectively calculate disease burden by using the modified Severity Weighted Assessment Tool (mSWAT). Researchers would also collect samples of your tumor tissue before subject starts chemotherapy to be used for the BDI testing in the laboratory by the Purdue University collaborative research team. The BDI testing will be done at baseline on day of collection. We would also evaluate subject's response to treatment after the 1st and 2nd cycles completion through PET/CT or CT scans, skin examinations, and/or laboratory tests depending upon subject's disease. The following is a list of what subjects can expect at each of their study visits.
Pre-treatment: Screening
- Subject Consenting - approximately 30 - 40 minutes
- Collect Demographic information, Medical History - approximately 5- 10 minutes
- Physical Exam/performance status: A physical exam will be performed by the doctor, and the doctor will document subjects' overall health and how well subjects are able to perform their activities of daily living.
- Skin biopsy: One or more areas of subject's skin that has the cancer will be cleansed with alcohol. The areas will be numbed by injecting a small amount of anesthesia in the skin. As part of routine biopsy procedures in the Department of Dermatology, photographs may be taken of the lesions/tumors that will be biopsied. When the areas of the skin are numb, 3 samples of your skin about 4-mm deep (6-mm wide skin punch biopsies), will be removed from one or more sites and sent for BDI testing. A small stitch will be placed in each biopsy site. Subjects will be given sterile wound dressings and wound care instructions including samples of petrolatum to allow subject to take care of the small wounds. The stitches from the biopsy sites will be removed 10-14 days later.
- Skin disease severity scoring: In order to determine the extent of subject's disease, the physician will physically examine subject's skin.

结局指标
主要结局
Development of phenotypic human MF biodynamic profiles
时间窗: Biopsy samples are collected and imaged prior to each subject's initiation of standard of care gemcitabine treatment
Dermal punch biopsy samples from subjects' cutaneous mycosis fungoides lesions will be analyzed using ex vivo BDI for sensitivity to gemcitabine. BDI measures intracellular motion patterns (biodynamic profiles) before and after gemcitabine is applied to the sample. Biodynamic profiles associated with poor intercellular organelle motility will be classified as phenotypic responders while those associated with normal intercellular organelle motility will be classified as phenotypic non-responders.
次要结局
- Percent of individual biodynamic profiles with cellular response correlating with individual clinical response.(After day 56 of study for each individual participant)
