Merck & Co, Inc, recently announced that the Food and Drug Administration (FDA) has approved oral vorinostat (Zolinza), 400 mg once daily, for the treatment of cutaneous manifestations in patients with cutaneous T-cell lymphoma (CTCL), a form of non-Hodgkin's lymphoma, who have progressive, persistent, or recurrent disease on or following two systemic therapies. CTCL is a cancer of the T cells that affects the skin.

Mechanism of Action
Vorinostat is a histone deacetylase (HDAC) inhibitor. Based on in vitro studies, the drug inhibits the enzymatic activity of HDAC1, HDAC2, HDAC3 (class I), and HDAC 6 (class II) at nanomolar concentrations. In some cancer cells, excess amounts of the enzyme HDAC prevent the activation of genes that control normal cell activity. Vorinostat is believed to decrease the activity of HDAC, allowing for the activation of genes that may help to slow or stop the growth of cancer cells. The exact mechanism of the agent's anticancer effect has not been fully characterized.
"With today's FDA approval of Zolinza, there is now an effective new option in the fight against cutaneous manifestations of cutaneous T-cell lymphoma, specifically in patients who have tried and failed other cancer treatment options," said Elise Olsen, MD, director, CTCL Clinic & Research Center at Duke University Medical Center and lead investigator of one of the studies that led to the approval.
Considering NCCN Guidelines to Determine Maintenance Therapy Multiple Myeloma
February 15th 2025During the 66th American Society of Hematology Annual Meeting and Exposition, experts in multiple myeloma gathered to discuss the impact of maintenance therapy and minimal residual disease (MRD) in patients with newly diagnosed transplant-eligible or -ineligible multiple myeloma.
