Diabetic Foot Ulcer | Biological: AUP1602-C | Phase 1 Phase 2 |
Study AP-W-CLI-2018-8 is the first clinical study of AUP1602-C in humans. It is a Phase 1/2A clinical study to evaluate the safety, tolerability and efficacy of a single and repeated doses of AUP-16 as topical treatment of DFU. The Phase 1 part will be a multicenter, open-label, non-randomized, uncontrolled dose-finding study with sequential dose escalations performed in dose cohorts comparing three doses of AUP-16 administered three times per week (low, medium, and high dose cohorts). This part will consist of four sequentially recruited cohorts. It is expected that a minimum of 15 patients may be required to determine the RP2D in phase 1 part.
The Phase 2A part, an extension of the Phase 1, will be a multi-center, open-label, randomized, placebo-controlled study of the recommended AUP1602-C dose and administration schedule from Phase 1 to confirm safety and to assess efficacy of the selected recommended phase 2 dose and schedule in DFU patients.

AUP1602-C is topically applied on chronic wounds and covered by wound dressing. |
- Incidence of adverse events (AEs) and potential dose-limiting toxicities (DLTs) [ Time Frame: 4 weeks ]Incidence of adverse events (AEs) and potential dose-limiting toxicities (DLTs) for safety, low, medium, and high dose cohorts of single and repeatedly administered AUP1602-C
- Incidence of Treatment-Emergent Adverse Events [ Time Frame: 6 months ]• Incidence of AEs
- Incidence of Wound Closure [ Time Frame: 6 months ]
- Percentage (%) of patients with a target ulcer achieving complete wound closure
- Percentage (%) of wound size reduction (wound area measurements in cm^2)
- Incidence of Wound Closure [ Time Frame: 6 months ]
- Percentage (%) of wound area (cm^2) reduction
- Percentage (%) of wound depth (mm) reduction
- Percentage (%) of wound volume (mm^3) reduction
Measurements will be aggregated: Wound are and depth will be used to calculate wound volume.
- Incidence of ulcer recurrence [ Time Frame: 6 months ]Percentage (%) of patients with ulcer recurrence
- Incidence of Wound Infections [ Time Frame: 6 months ]Proportion of patients with local wound infections related to the target ulcer
- Incidence of surgical procedures [ Time Frame: 6 months ]
- Number of patients with local surgical procedures
- Incidence of amputations (minor or major) related to the target ulcer
- Changes in Quality of Life according to EQ-5D-5L [ Time Frame: 6 months ]Change from baseline in health-related quality is assessed according to EuroQoL-5 Dimensions (EQ-5D-5L) patient quesionnaire. Five single-item dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) are assessed. Result of the questionnaire is scored from 0 (worst health imaginable) to 100 (best health imaginable).
- Changes in Quality of Life according to DLQI [ Time Frame: 6 months ]Change from baseline in health-related quality is assessed according to Dermatology Life Quality Index (DLQI). It consists of 10 questions, where each question is scored from 0 (not affected at all) to 3 (very much affected). The DLQI score will be calculated as the sum of the 10 individual question scores and ranges from 0 to 30, with lower scores indicating better quality of life.
- Changes in pain assessment according to VAS [ Time Frame: 6 months ]Change from baseline in patient's pain intensity according to a numerical Visual Analog Scale (VAS) ranging from 0 = no pain to 10= worst imaginable pain.
- Incidence of Adverse Events [ Time Frame: 6 months ]
- Incidence of abnormal vital signs
- Incidence of abnormal ECG data
- Incidence of abnormal echocardiogram data
- Incidence of abnormal ophthalmoscopy data
- Incidence of abnormal physical examination findings
- Incidence of abnormal laboratory data
- Incidence of bacteria distribution [ Time Frame: 6 months ]Assessment of biodistribution and shedding (yes / no)
