PinkDx is an early-stage company whose vision is to positively impact the health of women throughout their life journey. We focus on addressing the medical problems that women uniquely face by applying sophisticated scientific approaches to resolve them and provide answers that have an immediate, positive impact on their lives. Our first indication will focus on overcoming diagnostic challenges for women who present with general symptoms that could signal a gynecological cancer. Led by a team of diagnostics industry veterans, PinkDx is privately held, with funding from prominent biotechnology investors, including Catalio Capital Management, The Production Board, Mountain Group Partners, Byers Capital and Mayo Clinic.

Dextera Biosciences is developing a new category of drugs, Synthetic D-Proteins, to overcome the limitations of current drug modalities. Synthetic D-Proteins exhibit antibody-like specificity to a single therapeutic target but with the broad distribution of small molecules, all while being otherwise “invisible” to the rest of the body. The consequences are that we can deliver sustained antibody-like activity specifically to interstitial targets, enable oral delivery with complete metabolic stability, and extend therapeutic durability with no immunogenicity. We are focusing on debilitating diseases where significant unmet need remains due to the limitations of current drugs.

Metagenomi is a precision genetic medicines company committed to developing curative therapeutics for patients using our proprietary, comprehensive metagenomics-derived genome editing toolbox. We believe tools with capa­bil­i­ties that go beyond the cur­rent tech­nol­o­gy land­scape will be required in order to reach the full ther­a­peu­tic poten­tial of genome edit­ing. By har­ness­ing the pow­er of metage­nomics, the study of genomes recov­ered from uncul­ti­vat­ed organ­isms in the nat­ur­al envi­ron­ment, we are dis­cov­er­ing and devel­op­ing a suite of nov­el genome edit­ing tools with the poten­tial to make any desired ther­a­peu­tic gene edit, any­where in the human genome.

Epizyme, Inc. is a late-stage biopharmaceutical company rewriting therapy for cancer and other serious diseases through novel epigenetic medicines. Our pipeline is led by tazemetostat, an investigational agent that is an orally administered, first-in-class small molecule EZH2 inhibitor for the treatment of multiple types of hematological malignancies and genetically defined solid tumors. The company also is developing a novel G9a program with its next development candidate, EZM8266, which is targeting sickle cell disease. By focusing on the genetic drivers of disease, Epizyme's science seeks to match targeted medicines with the patients who need them. For more information, visit www.epizyme.com.
