Four years after its founding, Myeloid Therapeutics Inc. raised $73 million to advance mRNA immunotherapy technology that targets and activates myeloid cells. Proceeds from the financing will go toward MT-101, the company’s first autologous CAR monocyte, which is in a phase I/II trial for T-cell lymphoma. It also will accelerate development of MT-302, a potentially first-in-class TROP2-FcA mRNA lipid nanoparticle candidate, which is ready for a phase I/II study for TROP2-expressing solid tumors.

Biopharma financings are pacing more than $300 million higher than at the end of April last year, but are well behind the total through April 2021 when the value of financings more than doubled any recent year due to the response to the COVID-19 pandemic. Through the end of April, biopharmas have raised $19.83 billion this year, compared to $17.5 billion through the same month in 2022, $53.7 billion in 2021, $24.04 billion in 2020 and $19.53 billion in 2019.

Ray Therapeutics Inc.’s upsized and oversubscribed $100 million series A financing will support the firm’s ongoing efforts with optogenetics, an approach that deploys adeno-associated virus (AAV) gene therapy to deliver a light-sensitive, highly bioengineered protein found in nature to retinal cells.
