The purpose of this study is to determine safety and efficacy of a new gel formulation of Esmolol hydrochloride (Galnobax®) for the treatment of Diabetic Foot Ulcer (DFU). The study will compare number and types of adverse events occured, rates of wound closure and percentage of wounds closed in Galnobax treated groups versus placebo group.

This is an interventional, placebo-controlled, randomized, double-blinded, dose comparison, phase I/II study of Galnobax® in subjects with diabetic foot ulcers. Additionally the effect of dosage and frequency of application will also be studied . The total trial duration per subject is 25 weeks which comprises of 1 week for screening, 12 weeks of treatment and 12 weeks of follow-up.

Inclusion Criteria:

• Subjects aged 18 to 95 years, inclusive, with Type 1 or Type 2 diabetes undergoing therapy for glycemic control

• Ulcer should be clinically non-infected
• Ulcer area (length x width) measurement between 1.5 cm2 and 10 cm2, inclusive and post debridement ulcer area less than or equal to 12 cm2.
• Full-thickness ulcer of Grade 1 or Grade 2 as per Wagner's classification system
• Recently debrided ulcer (2 weeks prior to screening) and post debridement ulcer free of necrotic debris, foreign bodies, sinus tracts, tunneling, and undermining, comprised of healthy vascularized tissue as determined by the Investigator
• Inability to perceive 10 grams pressure using Semmes-Weinstein 5.07 monofilament in the peri-ulcer area
