About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled Pilot Study of the Safety and Efficacy of Deferoxamine Intradermal Delivery Patch (DIDP) in Chronic Sickle Cell Leg Ulcers
Approximately 60 subjects will be enrolled into this double-blind, placebo-controlled study for the Deferoxamine Intradermal Delivery Patch (DIDP).
Those subjects who pass Screening will enter into the 2-week Standard of Care (SOC) Run-In period. During this time, ulcers will be assessed to check healing based on digital planimetry, and qualitative features of the ulcer. Subjects who meet eligibility criteria at the end of the 2-week Run-in Period will be randomized into active and control groups (2 active to 1 placebo) and enter the 12-week Treatment Period. At each visit during the Treatment Period, the target ulcer will be measured by digital photographic planimetry, the Principal Investigator will assess the wound qualitative attributes, and the DIDP (or placebo patch) will be placed as the primary wound dressing. At each visit the subject will also receive/review a daily diary to document pain , study drug compliance, and analgesic use.
Read the detailed description
Approximately 60 subjects will be enrolled to allow for up to 48 male or female subjects with SCD and cutaneous ulcers to complete this double-blind, placebo-controlled study.
A sentinel group of 3 subjects will be enrolled and evaluated for safety (while still blinded). The remaining subjects will be enrolled in a 2:1 ratio, active:placebo.
Those subjects who pass Screening will enter into the Standard of Care (SOC) Run-In period. During this time, ulcers will be assessed to check healing based on digital planimetry, and qualitative features of the ulcer. Subjects who meet eligibility criteria at the end of the Run-in Period will be randomized and enter the 12-week Treatment Period.
The DIDP (or placebo) will be replaced daily at home. The subject will visit the clinic on an approximately weekly basis for study assessments, to include imaging and planimetric wound measurements and qualitative wound assessments. Clinical laboratory samples will be collected at Treatment Baseline, Treatment Weeks 4, 8 and 12, or at End of Study (EOS) visit if sooner. A blood sample for PK testing will also be collected at these timepoints. During this Treatment Period, if at any time the wound has met the criterion for 100% healing, the subject will immediately go into the 4-week Follow-up Period.
During the Follow-up Period, the subject will come to the clinic at 1-week intervals. At these visits, the area of the wound will continue to be protected with a protective dressing. Clinical laboratory samples will be collected at the Termination Visit.
Ulcer pain will be assessed by the subject daily and recorded in a diary, along with a record of analgesic use. At each visit, study staff will assist the subjects to assign an overall ulcer pain score for the week.
Quality of Life Assessment will be performed at Baseline prior to dosing and at End of Treatment.
Safety will be assessed based upon known adverse outcomes of Deferoxamine (DFO) therapy. Skin will be examined for evidence of rash and skin irritation.
