VelosBio, a biotech startup researching new cancer drugs, has raised $58 million in financing. The new VelosBio cash, a Series A round of financing, was led by Arix Bioscience (LSE: ARIX) and Sofinnova Ventures. VelosBio joined Johnson & Johnson’s JLABS @ San Diego incubator in January. The company is developing antibody drug conjugates, a class of cancer drugs that link antibodies to potent cancer-fighting toxins. These drugs are meant to provide a targeted strike to tumors, sparing healthy tissue. The new VelosBio cash is earmarked for completing the work needed to proceed into human studies.
