Brief Summary:
This is a two-part phase 1/2A study performed in diabetic foot ulcer (DFU) patients with chronic non-healing wounds to investigate the safety and efficacy of AUP1602-C.

Condition or disease Intervention/treatment Phase
Diabetic Foot Ulcer Biological: AUP1602-C Phase 1 Phase 2

Detailed Description:

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.

Arm Intervention/treatment
Experimental: AUP1602-C

Biological: AUP1602-C
AUP1602-C is topically applied on chronic wounds and covered by wound dressing.




Primary Outcome Measures :
  1. 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

  2. Incidence of Treatment-Emergent Adverse Events [ Time Frame: 6 months ]
    • Incidence of AEs

  3. 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)


Secondary Outcome Measures :
  1. 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.


  2. Incidence of ulcer recurrence [ Time Frame: 6 months ]
    Percentage (%) of patients with ulcer recurrence

  3. Incidence of Wound Infections [ Time Frame: 6 months ]
    Proportion of patients with local wound infections related to the target ulcer

  4. 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

  5. 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).

  6. 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.

  7. 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.

  8. 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

  9. Incidence of bacteria distribution [ Time Frame: 6 months ]
    Assessment of biodistribution and shedding (yes / no)
