NB Therapeutics

NB Therapeutics, also known as Nitric BioTherapeutics or Nitric Bio, was a private specialty pharmaceutical and medical device company focused on dermatology and podiatry. The company developed proprietary drug-delivery approaches centered on topical nitric oxide gas and iontophoresis to improve treatment of skin and nail diseases. Its disclosed clinical programs included nitric oxide for moderate-to-severe tinea pedis and iontophoretic terbinafine delivery for distal subungual onychomycosis, both studied in Phase 2 trials. Multiple secondary sources indicate the company was founded in the mid-2000s and headquartered in Bristol, Pennsylvania. More recent business databases suggest the company is no longer active, and there is no clear evidence of a completed acquisition.
