Senda Biosciences, Inc. is uniquely positioned to transform human health by harnessing millions of years of evolution to program targeted, potent and tunable medicines. Nature has provided the codes to program human cells – both within the cell (mRNA), and, remarkably, to the cell - using what surrounds it. The trillions of non-human cells in the human ecosystem have evolved natural nanoparticles that precisely shuttle biomolecules into human cells, providing the missing pieces to fully unlock programmable medicines. Senda’s proprietary platform includes the first-ever atlas of nature-derived programmable systems at the molecular level and across all kingdoms of life – accessing the entire code provided by nature required to program cells. With this platform, Senda is developing a new class of SendRNA™ medicines. The unique properties of these medicines create new frontiers for mRNA therapeutics and vaccines for infectious, genetic, autoimmune, and metabolic diseases and oncology indications – with further potential to transform the gene editing and protein-based therapy landscapes as well. Based in Cambridge, MA, Senda was founded by Flagship Pioneering.

Omega Therapeutics is a clinical-stage biotechnology company pioneering the first systematic approach of using mRNA as programmable epigenomic medicines. Our OMEGA platform harnesses the power of epigenetics, the mechanism that controls gene expression and every aspect of an organisms life from cell genesis, growth and differentiation to cell death. The OMEGA platform enables control of fundamental epigenetic processes to correct the root cause of disease by returning aberrant gene expression to a normal range without altering native nucleic acid sequences. Omega’s engineered, modular, and programmable mRNA medicines, Omega Epigenomic Controllers™, target specific intervention points amongst the thousands of mapped and validated novel DNA-sequence-based epigenomic loci to durably tune single or multiple genes to treat and cure disease through unprecedented precision epigenomic control. Omega has a broad pipeline of development candidates spanning a range of disease areas, including oncology, regenerative medicine, multigenic diseases including immunology, and select monogenic diseases.

Evelo Biosciences is a clinical stage biotechnology company developing orally delivered product candidates that are designed to act on the small intestinal axis, SINTAX™, with systemic therapeutic effects. SINTAX plays a central role in governing the immune, metabolic, and neurological systems. The Company’s first product candidates are pharmaceutical preparations of single strains of microbes selected for their potential to offer defined pharmacological properties. Evelo’s therapies have the potential to be effective, safe, and affordable medicines to improve the lives of people with inflammatory diseases and cancer.
Evelo currently has four product candidates in development: EDP1815, EDP1867, and EDP2939 for the treatment of inflammatory diseases and EDP1908 for the treatment of cancer. Evelo is advancing additional product candidates in other disease areas.

Avedro is a leading commercial-stage ophthalmic medical technology company focused on treating corneal ectatic disorders and improving vision to reduce dependency on eyeglasses or contact lenses. Avedro’s proprietary Avedro Corneal Remodeling Platform strengthens, stabilizes and reshapes the cornea utilizing corneal cross-linking in minimally invasive and non-invasive outpatient procedures to treat corneal ectatic disorders and correct refractive conditions. The Avedro Corneal Remodeling Platform is comprised of Avedro’s KXL and Mosaic systems, each of which delivers ultraviolet A light, and a suite of proprietary single-use riboflavin drug formulations, which, when applied together to the cornea, induce a biochemical reaction called corneal collagen cross-linking.

Seres Therapeutics is a commercial-stage company developing novel microbiome therapeutics for serious diseases. Our lead program, VOWST™, obtained U.S. FDA approval in April 2023 as the first orally administered microbiota-based therapeutic to prevent recurrence of C. difficile infection (CDI) in adults following antibacterial treatment for recurrent CDI and is being commercialized in collaboration with Nestlé Health Science. We are evaluating SER-155 in a Phase 1b study in patients receiving allogeneic hematopoietic stem cell transplantation to reduce incidences of gastrointestinal infections, bloodstream infections, and graft-versus-host disease as well as additional preclinical stage programs targeting Infection Protection in medically compromised patients. We are also conducting research to inform further development of microbiome therapeutics for ulcerative colitis.

We are passionate in our commitment to improving and renewing people's lives. Sesen Bio is a late-stage company developing fusion protein medicines for people with cancer. Our fusion protein approach tethers a tumor-targeting antibody fragment to a protein cytotoxic payload to form a single protein molecule designed to selectively and broadly kill cancer cells while sparing healthy cells and to activate the body’s innate immune response system.
The most advanced program in our pipeline is Vicinium™, a novel investigational anti-cancer treatment that has the potential to treat multiple cancers driven by overexpression of EpCAM, such as non-muscle invasive bladder (NMIBC) and squamous cell carcinoma of the head and neck (SCCHN). We are currently advancing Vicinium in a Phase 3 registration trial for the treatment of people with NMIBC who have been previously treated with bacillus Calmette-Guérin (BCG), with positive three-month efficacy results established and 12-month study results expected in mid-2019. Due to Vicinium’s potential to promote an anti-tumor immune response, we believe it holds promise as a combination treatment with immuno-oncology drugs, such as checkpoint inhibitors. The first assessment of this is in a clinical study combing Vicinium with AstraZeneca’s durvalumab, in NMIBC. For more information, please visit www.sesenbio.com.

Joule has pioneered a CO2-to-fuel production platform, effectively reversing combustion through the use of solar energy. The company’s platform applies engineered catalysts to continuously convert waste CO2 directly into renewable fuels such as ethanol or hydrocarbons for diesel, jet fuel and gasoline. Free of feedstock constraints and complex processing, Joule’s process can achieve unrivaled scalability, volumes and costs without the use of any agricultural land, fresh water or crops. Joule is privately held and has raised over $160 million in funding to date, led by Flagship Ventures. The company operates from Bedford, Massachusetts and The Hague, The Netherlands, with production operations in Hobbs, New Mexico. Additional information is available at www.jouleunlimited.com.
