Anthera Accused of Unjustifiably Touting Its Competitive Advantage

According to the complaint, on February 10, 2015, Anthera announced the successful completion of an interim analysis of its Phase 3 trial, known as CHABLIS-SC1, of blisibimod in patients with systematic lupub erythematosus ("SLE"). Anthera stated that it was pleased with the study's ability to pass a critical milestone and that "the [SLE Responder Index-6] endpoint has a history of consistency across multiple trials and represents the best possibility for success." Anthera also stated in a Form 10-K that it filed with the U.S. Securities and Exchange Commission that it believed that the CHABLIS-SC1 development program may offer many potential opportunities for differentiation as opposed to other offerings, and subsequently stated that the company expected to report topline efficacy data in the fourth quarter of 2016. However, the complaint alleges that Anthera officials failed to disclose that patients were not improving in the CHABLIS-SC1 clinical trial and that there were dosing problems inherent in its Solution Study design that created challenges to obtaining responses.

On November 10, 2016, Anthera announced in a press release that the CHABLIS-SC1 clinical trial failed to meet its primary endpoint based upon the SLE Responder Index-6 at 52 weeks. The company further expressed disappointment that the results did not demonstrate a meaningful improvement in patients' disease activity. Then, on December 27, 2016, Anthera announced the Solution Study missed the CFA non-inferiority margin of the primary modified Intent to Treat analysis. Anthera attributed the disappointing news to the structure of the study, which likely hindered the results by prohibiting some patients from increasing their dosage during the testing. On this news, Anthera's stock fell by 63% to close at $0.74 per share on December 28, 2016.
