Read MoreHide Full Article

Biogen Inc. (BIIB - Free Report) announced that it has dosed the first patient in the phase III study — TOPAZ-1 — that will evaluate its humanized IgG1 monoclonal antibody (mAb) candidate, BIIB059, in patients with active systemic lupus erythematosus (SLE). The late-stage study will be conducted across several sites globally and aims to enroll 540 active SLE patients, which will include African-American and Hispanic/Latinx communities.

Active SLE is a chronic autoimmune condition that can affect multiple organ systems and has limited treatment options. The TOPAZ-1 study will evaluate two doses of BIIB059 administered subcutaneously every four weeks and an additional dose at week 2 for reduction in disease activity. The primary endpoint of the study is proportion of patients achieving SLE Responder Index-4 response compared to placebo, following a year of treatment. Please note that the patients will continue to receive their existing lupus treatment during the study period.

The company initiated the late-stage study based on positive results from previously completed phase II LILAC study.

Shares of Biogen have soared 56.6% so far this year against the industry’s decrease of 1.5%.

As per data from LILAC study announced in December 2019, treatment with BIIB059 demonstrated statistically significant reduction of disease activity in patients with cutaneous lupus erythematosus and SLE in the LILAC study. The reduction in disease activity in SLE patients was achieved following 24 weeks of treatment.

Apart from BIIB059, Biogen is also developing another candidate, dapirolizumab pegol, in lupus patients. A phase III study was initiated to evaluate the candidate last year.

Meanwhile, Biogen has been in the news, following the FDA approval to its controversial investigational treatment for Alzheimer’s disease, aducanumab. The drug, to be marketed by the brand name of Aduhelm, has been approved to reduce the accumulation of amyloid beta plaques, a sticky protein, in the brain, which is believed to lead to progression of Alzheimer’s disease. However, an FDA advisory committee had voted against the drug’s approval, citing that clinical data does not provide strong evidence to support the efficacy of the drug.
