Trial for
Efficacy), evaluating INO-4800, its DNA vaccine candidate for COVID-19. Preliminary results show in a larger population that INO-4800 was generally safe, well-tolerated and immunogenic in all studied age groups.
Findings from the Phase 2 Clinical Trial:
The Phase 2 segment of the trial enrolled approximately 400 participants, 18 years of age or older, at 16 U.S. sites.
Participants received either INO-4800 (1.0 mg or 2.0 mg dose) or placebo at 0 and 4 weeks (randomized 3:3:1:1). Each dose was administered by intradermal injection followed by electroporation using INOVIO s CELLECTRA
®, its proprietary smart device.
Safety endpoints included systemic and local administration site reactions through 8 weeks post-dose one (or 4 weeks post-dose 2). Immunology endpoints included antigen-specific binding antibody titers, neutralization titers, and antigen-specific interferon-gamma (IFN-γ) cellular immune responses after two doses of the vaccine.

MRI of glioblastomas.
Immunotherapies that fight cancer have been a life-saving advancement for many patients, but the approach only works on a few types of malignancies, leaving few treatment options for most cancer patients with solid tumors. Now, in two related papers published April 28, 2021, in Science Translational Medicine, researchers at UCSF have demonstrated how to engineer smart immune cells that are effective against solid tumors, opening the door to treating a variety of cancers that have long been untouchable with immunotherapies.
By “programming” basic computational abilities into immune cells that are designed to attack cancer, the researchers have overcome a number of major hurdles that have kept these strategies out of the clinic up to now. The two new papers show that the resulting “smart” therapies are more precise, flexible and thorough than previous approaches, and the researchers say that their approach may be ready for clinical trials in the near fut

Short circuiting solid tumors
Two major hurdles in chimeric antigen receptor (CAR) T cell therapy for solid tumors are ensuring specificity to tumor cells without affecting healthy cells and avoiding tumor escape due to antigen loss. To address these challenges, Hyrenius-Wittsten
et al. and Choe
et al. developed synthetic Notch (synNotch)–CAR T cells targeting solid tumor antigens and used them to treat mouse models of mesothelioma, ovarian cancer, and glioblastoma. In both studies, the authors demonstrated that synNotch-CAR T cells were better at controlling tumors than traditional CAR T cells and did not result in toxicity or damage to healthy tissue. These results suggest that synNotch-CAR T cells may be an effective treatment strategy for solid tumors.
