INOVIO reported 2025 results alongside a major regulatory milestone for its lead DNA medicine INO-3107. The FDA accepted the Biologics License Application for recurrent respiratory papillomatosis under the accelerated approval program, with a PDUFA target date of October 30, 2026, while noting questions about accelerated approval eligibility that will be discussed at a future meeting.
The company advanced commercial readiness for INO-3107 and expanded its oncology and next‑generation DNA medicine pipeline, including a GBM collaboration with Akeso and published DMAb and DPROT data. INOVIO emphasized cost discipline, prioritizing INO-3107 and trimming roles not directly supporting this program.
Financially, 2025 research and development expenses fell to $54.2 million from $75.6 million, and general and administrative expenses declined to $32.7 million from $37.0 million, reducing total operating expenses to $86.9 million from $112.6 million. Net loss for 2025 narrowed to $84.9 million, or $1.81 per share, versus $107.3 million, or $3.95 per share in 2024; fourth‑quarter 2025 showed net income of $3.8 million, mainly from a $21.2 million non‑cash gain on warrant liabilities.
Cash, cash equivalents and short‑term investments were $58.5 million as of December 31, 2025, down from $94.1 million a year earlier, with 68,996,647 common shares outstanding. Management expects existing liquidity to fund operations into the fourth quarter of 2026, assuming an estimated operational net cash burn of about $22 million for the first quarter of 2026.
INOVIO Pharmaceuticals is a clinical-stage biotech focused on DNA medicines delivered with its proprietary CELLECTRA electroporation devices to treat HPV-associated diseases, cancer and infectious diseases. The company has no approved products and generates only collaboration and licensing revenue.
Its lead candidate, INO‑3107 for recurrent respiratory papillomatosis, has a Biologics License Application under FDA review with a standard 10‑month timeline and a PDUFA target date of October 30, 2026. The FDA has questioned whether current data support use of the accelerated approval pathway. INOVIO reports strong Phase 1/2 data showing durable reductions in surgery frequency.
The pipeline also includes INO‑3112 for HPV‑positive throat cancer, INO‑5401/INO‑5412 for glioblastoma and BRCA‑related cancers, and multiple infectious disease programs and DNA‑encoded antibody and protein platforms. Management discloses that INOVIO does not have sufficient working capital to fund planned operations for the next twelve months, raising substantial doubt about its ability to continue as a going concern and underscoring reliance on new capital.
