Physician Views: Can Lundbeck and Otsuka's newly approved Rexulti compete with branded and generic competition in the schizophrenia and depression markets?
FDA approval of Lundbeck and Otsuka Pharmaceuticals' Rexulti – which was announced last week – delivers a third atypical antipsychotic to the US market for the treatment of both schizophrenia and major depressive disorder (MDD).
Rexulti will not only compete with Abilify and Seroquel XR, but generic versions of the former – the branded also marketed by Otsuka – which have been available since US patent expiration in April. While FDA approval of Rexulti in both schizophrenia and MDD with similar labelling to competitors frames a ""best case scenario"" for the drug, remarked analysts at Jefferies, questions remain as to whether Lundbeck and Otsuka can sufficiently differentiate Rexulti from these competitors.
With Rexulti positioned as a successor to Abilify, Otsuka expects blockbuster sales to be achieved. The size of the US market for schizophrenia and MDD therapies, coupled with demand for new approaches to treatment, are supportive of such aspirations, suggest analysts at Credit Suisse. In a note to investors detailing approval of Rexulti last week, analysts at Deutsche Bank indicated that an improved tolerability profile versus Abilify could provide the best opportunity for Rexulti to emerge from the shadow of competition.
Given the size of the market, added analysts at Jefferies, ""while Rexulti may struggle to compete with established market-leading brands, if a new drug is able to become a second or third-line alternative and capture a small share of the market it could generate blockbuster revenues.""
