Just over a month after emerging from stealth and disclosing a $150 million series A, Korsana Biosciences Inc. is making the leap to the public market via a merger with Cyclerion Therapeutics Inc.  The agreement, which is backed by a $370 million private placement from Korsana’s investors, solidly positions the newly merged company as it heads toward the clinic with KRSA-028, a next-generation shuttled antibody targeting amyloid beta for the treatment of Alzheimer’s disease, and builds out a pipeline of neurodegenerative disease candidates.

In a publication in Molecular Pharmaceutics, researchers from Fudan University Shanghai Cancer Center China present the design and construction of a positron emission tomography-computed tomography (PET-CT) molecular imaging probe that accurately targets PRMT5, enabling real-time dynamic visualization and quantitative detection of PRMT5 expression levels.

Janux Therapeutics Inc. has nominated a development candidate under its collaboration and exclusive worldwide license agreement with Bristol Myers Squibb Co. (BMS). The milestone was achieved following the identification of a tumor-activated therapeutic, utilizing Janux’s TRACTr (Tumor Activated T Cell Engager) platform, targeting an undisclosed solid tumor antigen expressed across several human cancer types. The milestone triggers a payment to Janux.

Protein arginine methyltransferase 1 (PRMT1) is a key enzyme that catalyzes post-translational arginine methylation, thereby regulating diverse cellular processes, including gene transcription, RNA splicing, signal transduction, and DNA damage repair. As a central epigenetic and signaling regulator, PRMT1 plays a critical role in coordinating cellular proliferation, differentiation, and survival.
