NB-01+approach

NB-01+formulation


Posters

A poster on NeuroBo’s first candidate, NB-01, was presented at the NeuPSIG conference in London in May 2019. This study was conducted in Korea and shows that NB-01 was well tolerated in a Phase 2a safety study. The primary objective of this second Phase 2 study was to evaluate the efficacy of NB-01 in reducing pain in DPN. The secondary objective was to assess safety and tolerability of NB-01 in DPN.
