Phase I trial of phIL12 plasmid intratumoral gene electrotransfer in patients with basal cell carcinoma in head and neck region.

Introduction: In the treatment of cancer, immunomodulatory approaches are developed to support the organism in fighting cancer or to enhance the immunomodulatory effects of local ablative techniques. To this end, we conducted an interventional, open-label, single-arm Phase I trial to evaluate the safety and tolerability of intratumoral phIL12 plasmid DNA gene electrotransfer as primary objectives.

Methods: The study was dose-escalating with 3 consecutive cohorts of 3 patients per phIL12 dose level (0.

Engineered phage with antibacterial CRISPR-Cas selectively reduce E. coli burden in mice.

Antibiotic treatments have detrimental effects on the microbiome and lead to antibiotic resistance. To develop a phage therapy against a diverse range of clinically relevant Escherichia coli, we screened a library of 162 wild-type (WT) phages, identifying eight phages with broad coverage of E. coli, complementary binding to bacterial surface receptors, and the capability to stably carry inserted cargo.

Design and Preclinical Development of a Phage Product for the Treatment of Antibiotic-Resistant Infections.

Bacteriophages, viruses that only kill specific bacteria, are receiving substantial attention as nontraditional antibacterial agents that may help alleviate the growing antibiotic resistance problem in medicine. We describe the design and preclinical development of AB-SA01, a fixed-composition bacteriophage product intended to treat infections. AB-SA01 contains three naturally occurring, obligately lytic myoviruses related to phage K.
