SNIPR Biome, a Copanhagen-based clinical-stage biotech company pioneering precision medicines using CRISPR technology for microbial gene therapy, has secured $5.48 million in funding from the Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) to co-fund a Phase 1b/2a clinical trial in hematological cancer patients. The trial will evaluate SNIPR001, a CRISPR-armed phage therapeutic targeting E. coli in the gut, for the prevention of E. coli bloodstream infections in patients undergoing hematopoietic stem-cell transplantation (HSCT) and colonized with Fluoroquinolone Resistant (FQR) E. coli. SNIPR Biome intends to use this funding to advance SNIPR001 into clinical trials, focusing on safety, tolerability, pharmacokinetics, and pharmacodynamics in 24 patients across Europe and the United States.
Despite the significant advances in hematologic cancer therapy over the past decade, infectious complications, and antimicrobial resistance (AMR) continue to pose significant threats to patients and clinical outcomes1. Currently, there are no approved therapies for the prevention of bloodstream infections (BSIs) in hematological cancer patients. SNIPR Biome is developing SNIPR001 to address this urgent unmet need to combat infections in hematological cancer patients.
Preclinical data published in Nature Biotechnology described SNIPR001’s ability to selectively target and remove antibiotic-resistant E. coli strains in the gut, potentially offering a safe treatment which preserves the rest of the gut microbiome. This was supported by interim Phase 1 data published in 2023, which showed that oral dosing of SNIPR001 over seven days across three dosing levels in 24 healthy individuals was well tolerated. Furthermore, SNIPR001 could be recovered in faeces from treated individuals in a dose-dependent manner, and treatment with SNIPR001 numerically lowered gut E. coli levels.
Anticipated to begin later this year, the randomized, double-blinded Phase 1b/2a trial will investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of orally administrated SNIPR001 in 24 patients. It will be conducted at up to 10 sites across Europe and the United States.
CARB-X, a global non-profit partnership dedicated to supporting early-stage antibacterial research and development to address the rising threat of drug-resistant bacteria, has been a long-term collaborator with SNIPR in this field. The funding announced today enables SNIPR to move SNIPR001 into Phase 1b/2a clinical trials and will serve as a cornerstone for a further significant fundraise to enable the Company to continue development of its pipeline of CRISPR-based AMR and gut-directed gene therapies.
Dr Christian Grøndahl, Co-founder and CEO of SNIPR Biome, commented: “Antibiotic resistance is one of healthcare’s biggest problems today, affecting treatment efficacy and survival among patients who are often already very sick. We are using our knowledge of gene editing and synthetic biology to create highly specific, ‘designer’ bacteria and phage to disrupt, edit or add genes, and deliver these precision medicines in a carefully targeted way. We are pleased to be continuing our partnership with CARB-X who share our commitment to developing therapies for vulnerable patients.”
Erin Duffy PhD, Chief of Research & Development, CARB-X, said: “Having underscored safety for SNIPR001 in healthy subjects, SNIPR Biome is now focusing on demonstrating proof-of-mechanism for this novel product, with our support. We are keen to establish a link between gut decolonization and prevention of infection as a novel approach to antimicrobial resistance, and SNIPR001 offers the possibility of doing so.”
