Citius Pharma has faced common pharmaceutical industry risks, including competition and dependence on key personnel[28] - Citius Oncology faces significant competition from established pharmaceutical companies and research institutions in the development of its drug candidates[179] - Mino-Lok is currently the only product approved for the treatment of infected central venous catheters (CVCs) in patients with CRBSI/CLABSI[181] - Halo-Lido, if approved, would be the only prescription product for the treatment of hemorrhoids, competing against non-prescription OTC products[187] Intellectual Property and Agreements -
