INOVIO Reports First Quarter 2024 Financial Results and Recent Business Highlights (PRNewswire) - "The FDA provided feedback on the proposed Phase 3 trial design to evaluate the combination of INO-3112 and LOQTORZI as a potential treatment for patients with locoregionally advanced, high-risk, HPV-16/-18 positive throat cancer. INOVIO will discuss the proposed trial design with European regulatory authorities, as INOVIO plans to conduct the trial in both Europe and North America....The proposed multi-center Phase 3 trial will investigate whether LOQTORZI can help boost the tumor-infiltrating abilities of the antigen-specific T cells generated by INO-3112."

Feedback on the clinical development plan is expected in the second quarter of 2024. If cleared to proceed by the FDA, the trial will investigate if LOQTORZI can help boost the tumor-infiltrating abilities of the antigen-specific T cells generated by INO-3112."

In this single-institution retrospective study at a large academic referral center, both chemotherapy and immune checkpoint blockade were effective treatment options for patients with metastatic anal cancer. These data provide historical context in estimating median PFS necessary for future trial design in patients with metastatic anal cancer.
