Immunitas Therapeutics is a single cell genomics-based drug discovery company.
Calithera is discovering and developing novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer. Calithera Biosciences is a clinical-stage pharmaceutical company focused on discovering and developing novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer. Tumor metabolism and tumor immunology have emerged as promising new fields for cancer drug discovery, and recent clinical successes with therapeutic agents in each field have demonstrated the potential to create fundamentally new therapies for cancer patients. Our lead product candidate in tumor metabolism, CB-839, is an internally discovered, first-in-class inhibitor of glutaminase, a critical enzyme in tumor metabolism. We are currently evaluating CB-839 in three Phase 1 clinical trials in solid and hematological tumors. In tumor immunology, our lead preclinical program is directed at developing inhibitors of the enzyme arginase and may provide a first-in-class therapeutic agent for this novel target. Our ongoing research efforts are focused on discovering additional product candidates against novel tumor metabolism and immunology targets.
Cue Biopharma™ is an innovative immunotherapy company developing a novel, proprietary class of biologics engineered to selectively modulate the human immune system to treat a broad range of cancers and autoimmune disorders. We design biologics to engage and modulate the activity of disease-associated T cells in the patient`s body, offering significant therapeutic advantages while potentially minimizing or eliminating unwanted side effects. We believe our biologics allow us to target antigen-specific T cell populations in a variety of indications using a simple peptide exchange within previously-validated drug frameworks developed from the Cue Biologics Platform™. This flexibility could truncate the drug selection and development process, moving effective therapeutics from discovery to clinical validation more rapidly and cost efficiently than current industry standard timelines and costs. Headquartered in Kendall Square, Cambridge, MA, we are led by an experienced management team and scientific and clinical advisory board (SAB/CAB) with deep expertise in the design and clinical development of protein biologics, immunology and immuno-oncology.
SutroVax is a biopharmaceutical company dedicated to the delivery of best-in-class conjugate vaccines and novel complex antigen-based vaccines to prevent serious infectious diseases. SutroVax`s lead product candidate is a pneumococcal conjugate vaccine (PCV) that is designed to prevent invasive pneumococcal disease (IPD) caused by Streptococcus pneumoniae. SutroVax`s broad-spectrum PCV is designed to provide expanded protection against circulating strains of pneumococcus and has the potential to replace the current vaccines used in infants and adults. The current mainstay vaccine only covers approximately 40% of the circulating strains causing IPD yet generates $6B in annual sales. SutroVax has generated positive pre-clinical proof-of-concept with its significantly broader-spectrum PCV compared head-to-head to current vaccines using well accepted immunological endpoints. In addition to its lead PCV product candidate, the Company also has a promising early-stage pipeline addressing other important disease areas. SutroVax`s conjugate vaccines are developed utilizing the Company`s exclusive rights to Sutro Biopharma`s Xpress CF Platform, a cell-free protein synthesis technology. SutroVax closed its $85M Series C round in May of 2018 and is financed by a world-class syndicate of private equity, venture capital and corporate venture investors with over $170M in capital raised since 2015.
Arbutus Biopharma Corporation (Nasdaq: ABUS) is a clinical-stage biopharmaceutical company leveraging its extensive virology expertise to develop novel therapeutics that target specific viral diseases. Our current focus areas include Hepatitis B virus (HBV), SARS-CoV-2, and other coronaviruses. To address HBV, we are developing a RNAi therapeutic, an oral PD-L1 inhibitor, and an oral RNA destabilizer to potentially identify a combination regimen with the aim of providing a functional cure for patients with chronic HBV by suppressing viral replication, reducing surface antigen and reawakening the immune system. We believe our lead compound, AB-729, is the only RNAi therapeutic with evidence of immune re-awakening. It is currently being evaluated in multiple phase 2 clinical trials. We also have an ongoing drug discovery and development program directed to identifying novel, orally active agents for treating coronavirus (including SARS-CoV-2). In addition, we are exploring oncology applications for our internal PD-L1 portfolio.
