What this trial studies

This Phase 2 interventional trial gives adults with acute second-degree burns either 4-aminopyridine or a placebo and follows them through scheduled visits to measure healing and safety. Eligible burns must be at least 6 cm2 and treated within seven days of injury, with participants able to report sensory and motor changes. The investigational drug is given as an add-on to standard burn care so current infection control and fluid management continue. Primary outcomes focus on the speed and quality of wound closure and monitoring for any treatment-related adverse effects.

Who should consider this trial

Good fit: Adults aged 18–80 with acute second-degree burns of at least 6 cm2 occurring within the past 7 days who can consent and attend follow-up visits are ideal candidates.

Not a fit: People with full-thickness (third-degree) burns, chronic wounds, a history of seizure disorder, multiple sclerosis, significant renal impairment, or those outside the enrollment window or age range are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, patients could experience faster wound closure, fewer complications, and potentially reduced need for grafting or prolonged wound care.

How similar studies have performed: There is limited prior human burn-healing data for this approach; 4-aminopyridine has an established safety record in other conditions but little direct evidence yet for accelerating burn regeneration.
