Marketing Strategy/Execution
Istodax won US clearance in November for the treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior therapy. Gloucester has anticipated seeking approval next year for Istodax for peripheral T-cell lymphoma (PTCL), a larger market.
The aquisition of Celgene over Gloucester could leverage its marketing infrastructure to sell Istodax. Istodax poses a competitive threat for Allos Therapeutics’ newly approved Folotyn that could become more imposing with Celgene’s marketing muscle behind it. The attainment of Gloucester by Celgene introduces a deeper-pocket competitor into the field and could make Istodax a more viable threat.
Physician Outlook
Istodax is the second histone deacetylase (HDAC) inhibitor to be approved for cutaneous T-cell lymphoma after Zolinza (vorinostat, Merck). Its initial approval is as second- or later-line therapy in a rare (but hard-to-treat) disease. It is considered reasonably well tolerated, with the common toxicities (most notably, nausea, fatigue, and myelosuppression) of other therapies for hematologic malignancies. In the long run, it has promise as a therapy for more common malignancies such as B-cell lymphomas, as it has shown synergy with a variety of other therapies in preclinical studies — including the CD-20 inhibiting antibodies such as Rituxan (rituximab, Genentech) that are a mainstay of the treatment of lymphoma.
