cretostimogene grenadenorepvec (CG0070)

We highlight trials where OVs prime checkpoint response (e.g., DNX-2401→pembrolizumab in recurrent glioblastoma) and where vector design (e.g., TK-deleted vaccinia, CG0070) or payloads (e.g., IFNβ, NIS) drive measurable benefit. We conclude with actionable priorities, patient selection by IFN-pathway competence, receptor-tropism panels, and rational OV-ICI sequencing, to accelerate durable responses.

Nadofaragene firadenovec, a recombinant adenovirus delivering interferon alpha-2b (IFNα2b), is the first FDA-approved gene therapy for BCG-unresponsive NMIBC with carcinoma in situ (CIS)...Cretostimogene grenadenorepvec (CG0070), an oncolytic vector, demonstrated a 47% 6-month CR rate in a phase II study (NCT02365818). Detalimogene voraplasmid (EG-70), a nonviral gene therapy, demonstrated a 47% 6-month CR in a phase I/II study (NCT04752722). Future advances are likely to focus on patient selection, novel vectors, and combination strategies to improve treatment outcomes. Gene therapy represents a significant addition to the bladder cancer treatment landscape by offering bladder-sparing alternatives where conventional therapies are limited.

Emerging BSTs include immune checkpoint inhibitors like pembrolizumab and novel agents such as nadofaragene firadenovec and nogapendekin alfa inbakicept (IL-15)...Gene therapies and targeted agents like CG0070 and EG-70 are also gaining traction for their innovative mechanisms...Despite advancements, challenges remain in balancing efficacy, safety, and cost-effectiveness within diverse healthcare settings. This narrative review highlights the evolving landscape of BSTs for HR-NMIBC, emphasising the need for robust clinical evidence to refine patient selection and optimise outcomes.

Here we launched a phase 1b study using the combination of intravesical cretostimogene grenadenorepvec (oncolytic serotype 5 adenovirus encoding granulocyte-macrophage colony-stimulating factor) with systemic nivolumab in cisplatin-ineligible patients with cT2-4aN0-1M0 muscle-invasive bladder cancer. Together, these results highlight the potential of this combination regimen to enhance therapeutic efficacy in cisplatin-ineligible patients with muscle-invasive bladder cancer, warranting additional study as a neoadjuvant therapeutic option.
