Raquel Rodrigues. Using spore-forming bacteria to treat cancer: recent advancements in clostridial-based therapies

Posted on: Jul 29, 2023, 12:16:40

Description: The use of bacteria in cancer therapy has emerged as a promising approach, offering unique advantages for targeted treatment and immunotherapy. This review paper explores some recent advances in the application of bacteria, particularly Clostridium species, in cancer therapy. For instance, the Clostridial-Directed Enzyme Prodrug Therapy (CDEPT) utilises non-pathogenic strains of Clostridium as carriers for targeted delivery of anti-cancer drugs to solid tumour cells. This strategy aims to minimise systemic side effects associated with traditional chemotherapy. Additionally, Clostridium novyi and Clostridium sporogenes present oncolytic properties and have shown potential for tumour regression in preclinical models. The engineering of these bacteria to produce cytokines, such as interleukin-12 (IL-12) and interleukin-2 (IL-2), further enhances their therapeutic potential by activating the immune system to target cancer cells. Clinical trials in humans have demonstrated the feasibility and safety of C. novyi-based therapies, and early results indicate potential efficacy in tumour regression. Overall, this review provides valuable insights into the multifaceted roles of bacteria, particularly Clostridium species, in cancer therapy, emphasizing their potential as targeted therapeutics and immunomodulators for improved cancer treatment outcomes.
