NanoBio Corporation reported top-level findings from its phase 2b study of NB-001, a topical lotion to treat herpes labialis (cold sores).
The randomized, double-blind, vehicle- controlled study met its primary and secondary endpoints by demonstrating clear efficacy and safety in 482 patients.
NanoBio's uniquely formulated lotion resulted in faster healing of cold sores, at a rate never seen before by a topical product. The company's targeted phase 3 dose demonstrated highly statistically significant clinical efficacy in phase 2b at a magnitude comparable with or superior to what has been reported for the leading oral (systemic) anti-herpetic drugs on the market today.
Additionally, NB-001 demonstrated an excellent safety profile, with no serious adverse events, significant skin irritation or systemic blood absorption. In contrast, leading oral systemic treatments for herpes labialis carry label warnings that include nausea, diarrhea, vomiting, rash and migraine.
"Through this trial, we have confirmed that NB-001 achieves the efficacy of leading systemic treatments without presenting safety, drug interaction or toxicity risks," said James R. Baker Jr., MD, founder and chairman of NanoBio Corporation. "Based on the data, NanoBio will move immediately to initiate plans to begin phase 3 testing of NB-001 in early 2009." The full data set from the phase 2b study will be presented following a standard peer review process.
