NCT04945161

Brief Summary

The primary objective is to explore the mechanistic role of ON101 cream in healing diabetic foot ulcers by determining the molecular targets of ON101 cream. Primary endpoint: Percentage change from baseline in the expression level of individual target gene(s) at protein and/or mRNA level. Secondary endpoints:

  1. 1.Comparison of the gene and/or protein expression level of individual target between ON101 and Placebo groups
  2. 2.Change from baseline in the wound microbiota composition in each group
  3. 3.Comparison of the wound microbiota composition between ON101 and Placebo groups
  4. 4.Comparison of the wound reduction rate in each group
  5. 5.Correlation of wound reduction rate with the alternated level of each target gene in each group.

Study Arms (2)

Arm A: N = 6 ON101 plus SoC

EXPERIMENTAL

Twelve (12) eligible subjects with DFUs will be enrolled. These 12 subjects will be randomly assigned to receive either ON101 treatment plus SoC (Arm A) or Placebo plus SoC (Arm B) for six weeks. Treatment arm allocation will be done through randomization in a double-blind fashion. SoC will be provided from screening to the end of treatment. The SoC includes evaluation to ensure adequate arterial flow, wound cleaning, removal of necrotic, infected and/or nonviable tissue by debridement, maintenance of moist wound environment via regular changing of dressings, and management of infection through oral antibiotics, if necessary.

Drug: ON101 Cream

Arm B: N = 6 Placebo plus SoC

PLACEBO COMPARATOR

Twelve (12) eligible subjects with DFUs will be enrolled. These 12 subjects will be randomly assigned to receive either ON101 treatment plus SoC (Arm A) or Placebo plus SoC (Arm B) for six weeks. Treatment arm allocation will be done through randomization in a double-blind fashion. SoC will be provided from screening to the end of treatment. The SoC includes evaluation to ensure adequate arterial flow, wound cleaning, removal of necrotic, infected and/or nonviable tissue by debridement, maintenance of moist wound environment via regular changing of dressings, and management of infection through oral antibiotics, if necessary.

  • No higher than the ankle.
  • Subject has adequate vascular perfusion of the affected limb, confirmed by Ankle-Brachial Index (ABI) ≥ 0.8 and ≤ 1.3.
  • Clinically normal resting ECG at the first Screening Visit (V0) or, if abnormal, considered to be not clinically significant by the Investigator.
  • Subject must use an off-loading method for the target ulcer on the plantar during the whole study period.
  • Subject, if female of child-bearing potential, has a negative pregnancy test on urine at screening, must not be breastfeeding, and willing to use two medically accepted methods of contraception (e.g., barrier contraceptives \[female condom or diaphragm with a spermicidal gel\], hormonal contraceptives \[implants, injectables, combination oral contraceptives, transdermal patches, or contraceptives rings\], and intrauterine devices) during the course of the study (excluding women who are not of childbearing potential and/or who have been sterilized).
  • Subject is able and willing to comply with the study procedures.
  • A signed and dated informed consent form has been obtained from the subject.

You may not qualify if:

  • In response to standard of care (SoC), ulcer size reduction is ≥20% during the two-week run-in screening period (between the first Screening Visit/V0 and Baseline Visit/V1).
  • Ulcers with exposed bone or associated with osteomyelitis. Note: The osteomyelitis should be ruled out by clinical examination (probing of the wound) or X-ray findings where find necessary by the Investigator.
  • Presence of necrosis, purulence, or sinus tracts that cannot be removed by debridement.
  • Laboratory values at Screening of:
  • Liver function test (total bilirubin, aspartate aminotransferase \[AST\], or alanine transaminase \[ALT\]) \> 3x the upper limit of normal, or
  • Albumin \< 2.5 g/dL, or
  • Renal function test (serum creatinine or urea) \> 2x the upper limit of normal
  • Presence of any clinically significant medical condition(s) in medical history during screening period that, in the opinion of the Investigator, could interfere with wound healing, including but not limited to the following:
  • Acute or unstable Charcot foot
  • Current sepsis
  • Active malignant disease. A subject, who has had a malignant disease in the past, was treated and is currently disease-free, maybe considered for study entry.
  • Acquired immune deficiency syndrome (AIDS) or HIV positive
  • Subject is currently receiving (i.e., within 30 days of randomization visit) or scheduled to receive any of the following medication or therapies, could interfere with wound healing during the course of the study:
  • Immunosuppressive or chemotherapeutic agents, radiotherapy, or systemic corticosteroids
  • Autoimmune disease therapy
