The company is developing a novel T-cell engagers class to use the body's immune system to fight infection. Harpoon currently has several products in various stages of clinical trials, such as HPN328, which is in Phase I/II clinical trials for the treatment of small cell lung cancer and other Delta-like canonical Notch ligand 3-expressing tumors and HPN217, which is in Phase I/II clinical trials for the treatment of multiple myeloma. Shares of Harpoon have skyrocketed following the release of data from its Phase 1 clinical trial for HPN217, a single-agent candidate for pretreated patients with relapsed/refractory multiple myeloma (RRMM). The data showed clinical activity and a "tolerable safety profile," with low-grade CRS observed in 29% of patients following the first or second doses of the drug and no incidents of "Grade 3 or higher CRS." Analysts have a consensus price target of $8.75 on the stock, suggesting over 85% upside potential.
