Exploring the Effect of Fespixon Cream for the Treatment of Diabetic Foot Ulcers (TEXAS 3A, 3B)
Study Details
Study Description
Brief Summary
A Research Study to evaluate the therapeutic effect of Fespixon cream in patients suffering from DFU (UTWCS Grade III-A or III-B) by measuring the change of grade of UTWCS (University of Texas Diabetic Wound Classification system), wound area reduction, infection control, and incidence of treatment-emergent adverse event (TEAE).

Detailed Description
This study is designed as a single-arm, open-label, one-center study to evaluate the therapeutic effect of Fespixon cream in patients suffering from DFU (UTWCS Grade III-A or III-B). The duration of this study is: run-in/ screening phase (7 days ± 3 days); treatment phase (12 weeks); follow-up phase (2 weeks ± 4 days), and visits are conducted every week during the run-in/ screening phase and every 2 weeks during the treatment phase and follow-up phase for a total of 9 visits. During the treatment phase, the Fespixon cream will be applied to the target ulcer twice a day for a maximum period of 12 weeks, until the target ulcer downgrade from UTWCS grade III-A or III-B to I-A, I-B, II-A, or II-B for two consecutive visits at least 2 weeks apart, or until the subject exited the study as treatment failure. After that, all subjects regardless of wound grade-down at the end of the treatment phase will be followed for 2 weeks. During the follow-up phase, standard of care or other treatment modalities (with an exception of investigational treatment/ medications) will be used for all subjects at the discretion of the investigator.
At each visit, the size and changes of the target ulcer are recorded by photographing. The target ulcer area in the photo is calculated using Image-Pro® Plus software.

Outcome Measures
Primary Outcome Measures
- Incidence of the grade down of the target ulcer [12 weeks]
Ulcer grade down is defined as ulcer downgrading from 3A or 3B to 1A, 1B, 2A, or 2B confirmed at two consecutive study visits 2 weeks apart.
- Time to the ulcer grade down [12 weeks]
Ulcer grade down is defined as ulcer downgrading from 3A or 3B to 1A, 1B, 2A, or 2B confirmed at two consecutive study visits 2 weeks apart. Time to the ulcer grade down was defined as "time to the first visit of ulcer grade down of the target ulcer."
Secondary Outcome Measures
- Mean change from baseline in the target ulcer area confirmed by Image-Pro® Plus calculation of the wound area [12 weeks]
The target ulcer area at each visit is confirmed by Image-Pro® Plus software and presented as a mean change from the baseline.
- Percentage change from baseline in the target ulcer area confirmed by Image-Pro® Plus calculation of the wound area [12 weeks]
The target ulcer area at each visit is confirmed by Image-Pro® Plus software and presented as a percentage change from the baseline.
- Percentage of ulcer improvement [12 weeks]
Ulcer improvement is defined as ulcer downgrading from 3A or 3B to 1A, 1B, 2A, or 2B confirmed at two consecutive study visits 2 weeks apart.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Subjects, male or female, aged 20 to 80 years (inclusive) with Type 1 or Type 2 diabetes undergoing therapy for glycemic control using available diabetes drugs including insulin.
-
Subject has a glycosylated hemoglobin, HbA1c ≤ 12%.
-
Presence of at least one diabetic foot ulcer that meets all of the following criteria:
-
A full-thickness ulcer of UTWCS Grade III-A or III-B
-
Ulcer size (area) is >2 cm2 and ≤20 cm2 (post-debridement at time of enrollment)
-
Ulcer is located on or below the malleoli.
-
Ulcer presents for >1 week (at time of enrollment).
-
There is a minimum 3 cm margin between the qualifying Target Ulcer and any other ulcers on the specified foot, (post-debridement).
-
The infection severity of the target ulcer is defined as uninfected, mild, or moderate infection by IDSA/ IWGDF Guidelines. (IDSA/IWGDF-defined severe infection would be excluded)
Note:
-
If the subject has more than one qualifying diabetic foot ulcer, the most severe ulcer will be designated as the target ulcer; meanwhile, the depth of the wound will the consideration prior to the area of the wound.
-
Any foot infection with the following signs of a systemic inflammatory response syndrome is defined as severe infection according to IDSA Infection Severity.
This response is manifested by two or more of the following conditions:
-
temperature>38℃ or <36℃
-
heart rate > 90 beats/minute
-
respiratory rate > 20 breaths/minute or PaCO2 < 32 mmHg

-
use of any investigational drug(s)
