Shares of Harpoon Therapeutics Inc. surged 90% to $2.19 on Monday after the clinical-stage immuno-oncology company developing novel T cell engagers presented interim data from its trial targeting relapsed/refractory multiple myeloma.
Shares reached an intraday high on Monday of $3.35, a level last seen April 13 when shares reached a high of $3.42, according to FactSet. For the year, shares traded 71% lower.
Harpoon said its single-agent HPN217 demonstrated continued evidence of clinical activity and a tolerable safety profile in heavily pre-treated patients with RRMM, according to the interim results.
A majority of responders had decreases in the serum B-cell maturation antigen biomarker by week two of treatment, the company said. Also, 86% of responders remain on study treatment with sustained response, with many responders on treatment for over a year.
The results were presented at the American Society of Hematology annual meeting in New Orleans.
