Randomized, Double-blind, Vehicle-controlled 2-Arm Trial of Topical PluroGel N for the Treatment of Patients With Mildly Infected Diabetic Foot Ulcer CLINICAL PROTOCOL PGN-1300

This will be a randomized, double-blind (evaluator-blind), vehicle-controlled study of 50
enrolled subjects. Adult subjects (greater than 18 years old) who present with a mildly
infected diabetic foot ulcer (IDSA criteria) having full thickness (i.e., through the dermis
but not involving joint capsule, tendon, and bone). Subjects must also provide informed
consent and meet all other entry criteria to be enrolled and randomly assigned to receive
PluroGel N or PluroGel vehicle.


Inclusion Criteria:

- Non-hospitalized subjects with Type 1 or Type 2 diabetes mellitus as defined by the
American Diabetes Association diagnostic criteria (ADA, 2010). Diabetes may be
treated with insulin, oral hypoglycemic agents, diet, or a combination of these
therapies. Subjects whose diabetes is considered "controlled" by diet or medication
in the opinion of the physician.

- Males or females at least 18 years old.

- Subjects must be considered by the investigator to be reliable, willing and able
to give signed informed consent, and must sign the informed consent form.

- Subjects must have a full thickness (i.e., extending through dermis but not
involving tendon, bone, or joint capsule) ulcer on the foot distal to the
malleoli with a surface area ≥1 cm2 after the wound has undergone appropriate
debridement. Subjects must have localized mild infection of the ulcer, as
defined by the IDSA criteria as per Appendix C, with in the PGN1300 Protocol,
which the investigator believes would ordinarily be treated on an outpatient
basis.

IDSA mild infection of an ulcer is defined as:

The presence of ≥2 of the following items:

- Local swelling or induration

- Erythema

- Local tenderness or pain

- Local warmth

- Purulent discharge (thick, opaque to white or sanguineous secretion) Local infection
involving only the skin and the subcutaneous tissue. If erythema, must be >0.5 cm to
≤2 cm around the ulcer.

- Diabetic Foot Infection-General Parameters Score of at least 2 must be obtained
in order to be eligible for enrollment.

- Diabetic Foot Infection-Wound Size Score of at least 1 must be obtained in order
to be eligible for enrollment.

- The diagnosis of mild infection must be confirmed immediately following the Day
0 (Enrollment Visit) debridement, although pre-debridement purulence is to be
counted as one manifestation of infection.

Exclusion Criteria:

- Subjects with IDSA-defined moderate infection as per Appendix C, including cellulitis
extending > 2 cm; lymphangitis; spread beneath the fascia; deep tissue abscess;
osteomyelitis; gangrene; muscle, joint, or bone involvement.

- Subjects with IDSA-defined severe infection as per Appendix C, within PGN1300
Protocol including systemic toxicity or metabolic instability (e.g., fever,
chills, tachycardia, hypotension, confusion, vomiting, leukocytosis, acidosis,
hyperglycemia, or azotemia).

- Subjects with systemic inflammatory response signs, as manifested by ≥2 of the
following :

- Temperature >38°C or <36°C

- Heart rate >90 beats/min

- Respiratory rate >20 breaths/min or PaCO2 <32 mm Hg

- White blood cell count >12 000 or <4000 cells/μL or ≥10% immature (band) forms

- Subjects with local wound complications (e.g., prosthetic materials).

- Subjects currently receiving antibiotic treatment for a localized infection of
the study ulcer and whose infection is improving in response to treatment.

- Subjects requiring concurrent systemic antimicrobials during the study period
for any infection, including diabetic foot ulcer.

- Subjects in whom bone or joint involvement is suspected based on clinical
examination (e.g., bone noted visually or by probing) or plain view X-ray.

- Subjects with clinically significant peripheral arterial disease requiring
vascular reconstructive surgery. Subjects who are expected to be unable to care
for their ulcer because of hospitalization, vacation, disability, etc. during
the study period, or are unable to safely monitor the infection status at home.

- Subjects with known active alcohol or substance abuse within the 6 months
preceding study entry.

- Subjects who are receiving immunosuppressive agents (other than
corticosteroids), radiation therapy, or cytotoxic agents.

- Subjects who require treatment for a primary or metastatic malignancy (other
than squamous or basal cell carcinoma of the skin).

- Subjects with a systemically immunocompromising disease, such as acquired immune
deficiency syndrome or known human immunodeficiency virus infection.

- Subjects who have had an unexplained fever or chills during the week prior to
enrollment.

- Subjects with other conditions considered by the investigator to be reasons for
disqualification that may jeopardize subject safety or interfere with the
objectives of the trial (e.g., acute illness or exacerbation of chronic illness,
lack of motivation, history of poor compliance).

- Subjects with any known allergy or other contraindication to any ingredients in
the study products.

- Women who are breast feeding, pregnant, or not using contraception unless
sterile.

- Subjects who have been taking or expect to be taking any other investigational
therapy within the 30 days prior to entry or during enrollment.
