Matinas BioPharma (NYSE AMER: MTNB) is a biopharmaceutical company focused on improving the intracellular delivery of nucleic acids and small molecules with its lipid nanocrystal (LNC) platform technology. The Company is developing its own internal portfolio of products as well as partnering with leading pharmaceutical companies to develop novel formulations that capitalize on the unique characteristics of the LNC platform. Preclinical and clinical data have demonstrated that this novel technology can provide solutions to many of the challenges in achieving safe and effective intracellular delivery, for both small molecules and larger, more complex molecules, such as mRNA, DNA plasmids, antisense oligonucleotides, and vaccines. The combination of a unique mechanism of action and flexibility with formulation and route of administration (including oral), positions Matinas’ LNC technology to potentially become the preferred next-generation intracellular drug delivery vehicle with distinct advantages over both lipid nanoparticles and viral vectors.

Stoke Therapeutics (Nasdaq: STOK), is a biotechnology company dedicated to addressing the underlying cause of severe diseases. The company is pursuing an entirely new approach to treating severe diseases. We are initially focused on diseases of the central nervous system and the eye, with an emphasis on haploinsufficiencies, which are diseases caused by a loss of about half of the normal protein function. Rather than replace, repair or edit faulty genes, we aim to increase – or stoke – protein output from healthy genes to restore functional protein levels using our proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) platform. In all, Stoke has identified ~6500 genes with a TANGO signature, representing broad potential for our approach to help people with severe diseases. The early results have been promising. Stoke’s first medicine in development, STK-001 has demonstrated positive Phase 1/2 results for the treatment of Dravet syndrome, a severe and progressive genetic epilepsy that is associated with a number of debilitating non-seizure comorbidities. Behind that, is STK-002, a potential treatment for autosomal dominant optic atrophy (ADOA), the most common inherited optic nerve disorder. Clinical studies of STK-002 are anticipated to start in 2024. The company is pursuing potential treatments for three additional neurodevelopmental disorders, including Syngap1 and Rett syndrome, in collaboration with Acadia Pharmaceuticals. Stoke is headquartered in Bedford, Massachusetts with offices in Cambridge, Massachusetts.
