Novan Reports Topline Results from SB204 Phase 3 Pivotal Trials

Topical Acne Product Candidate Achieves Statistical Significance on All Three Co-Primary Endpoints in
One Trial, Demonstrates Statistical Significance on Only One of Three in the Second

Company Continues to Analyze Trial Data to Better Understand These Results

MORRISVILLE, N.C., Jan. 27, 2017 (GLOBE NEWSWIRE) -- Novan, Inc. (NASDAQ:NOVN) today announced  top-line results from the Company’s two, replicate Phase 3 pivotal clinical trials for SB204 in the treatment of acne vulgaris. In the intent-to-treat analysis, Novan’s topical nitric oxide-releasing product candidate SB204 demonstrated statistical significance (p<0.05) compared to vehicle on all three co-primary endpoints in NI-AC302, but demonstrated statistical significance on only one of three co-primary endpoints in NI-AC301. The three co-primary endpoints included the absolute changes in inflammatory and non-inflammatory lesion counts and proportion of patients achieving success on the Investigator Global Assessment, or IGA, at week 12. Success was defined as an improvement of at least two grades in the IGA score from baseline and an IGA score of 0 or 1, or “clear” or “almost clear.”

In these two Phase 3 multi-center, randomized, double-blinded, vehicle-controlled, parallel group pivotal clinical trials, NI-AC301 and NI-AC302, a total of 2,639 patients ages 9 and older with moderate to severe acne were enrolled across a total of 110 sites in the United States, randomized in a 1:1 ratio to SB204 Gel 4% topically once-daily or vehicle gel topically once-daily and treated for 12 weeks. No new safety signals were observed and both treatments were generally safe and well tolerated, with less than 2% of patients discontinuing due to treatment-emergent adverse events in each trial. Summary statistics are based on the use of a multiple imputation methodology for missing data.

  • The absolute change from baseline in the number of non-inflammatory lesions in NI-AC301 was -15.4 for SB204 and -13.4 for vehicle (p=0.030), and in NI-AC302 was -14.9 for SB204 and -12.3 for vehicle (p=0.001). 
  • The absolute change from baseline in the number of inflammatory lesions in NI-AC301 was -12.1 for SB204 and -11.1 for vehicle (p=0.114), and in NI-AC302 was -12.9 for SB204 and -10.6 for vehicle (p<0.001). 
  • The proportion of patients with IGA success in NI-AC301 was 13.4% for SB204 and 13.8% for vehicle (p=0.866), and in NI-AC302 was 18.9% for SB204 and 14.3% for vehicle (p=0.032).

The secondary endpoints for percent change in lesion counts are shown in the table below for each study along with the proportion of subjects achieving IGA success.

                                           NI-AC301   NI-AC302   
  Non-Inflammatory Lesion Reduction                      
  SB204, 4% 39 %* 42 %*  
  Vehicle 34 % 34 %  
  Inflammatory Lesion Reduction      
  SB204, 4% 46 % 51 %*  
  Vehicle 43 % 41 %  
  IGA Success      
  SB204, 4% 13.4 % 18.6 %*  
  Vehicle 13.8 % 14.3 %  *p<0.05

“While we are pleased with the results of the NI-AC302 trial that met the regulatory requirement for statistically significant efficacy of SB204, we are disappointed with the discordant results of NI-AC301. Our team has not yet received the full data set and we intend to provide an update on the SB204 program after our complete analysis,” said Nathan Stasko, PhD, President and CEO of Novan. “Despite these discordant results, we believe in the potential of nitric oxide’s multiple, well-documented mechanisms of action and the data we have recently generated for our SB206 anti-viral and SB414 anti-inflammatory product candidates. We continue to look forward to near term clinical results from our SB208 anti-fungal program in the second quarter of 2017 and advancing our pipeline of innovative therapies for patients suffering from skin diseases.”

The Company believes that its cash on hand is sufficient to fund operations at least through the end of 2017, of which the allocation of capital will be dependent upon further assessment of the SB204 Phase 3 trial results and data from other platform programs.
