Harpoon Therapeutics Orphan Status for Myeloma Drug
FDA has granted Harpoon Therapeutics an orphan drug designation for HPN217 for treating multiple myeloma. The tri-specific T cell activating recombinant protein construct targets B-cell maturation antigen, which is expressed on malignant multiple myeloma cells, the company says. Last April, Harpoon announced dosing of the first patient with HPN217 in a Phase 1/2 clinical trial focused on relapsed/refractory multiple myeloma. HPN217 has been well tolerated, and no dose limiting toxicities were observed up to the most recent data cutoff date (12/1/2020), the company says. A presentation of interim data is expected later this year, and the initiation of a dose expansion cohort in the second half of this year is planned.
