Jetpack

Jetpack Bio is a biotechnology company developing next-generation cell therapies designed to treat solid tumors. The company's core technology involves "Jetpacks," which are specialized payloads tethered to the surface of CAR-T cells to provide localized support, such as cytokines, within the tumor microenvironment. This localized delivery mechanism is intended to enhance the potency and persistence of the cells while avoiding the systemic toxicity often associated with high-dose cytokine administration. Founded by pioneers in synthetic biology from UCSF, Jetpack Bio aims to transform the landscape of immunotherapy for hard-to-treat cancers.
