The present disclosure relates to methods of using cisplatin active agents in which reduced organ toxicity is observed are provided. In the subject methods, an effective amount is administrated to the host before administration of an effective amount of cisplatin active agents. The cisplatin toxicity reducing agent comprising of stable bismuth(III) complexes or pharmaceutically acceptable salts reduces the levels of undesired toxicity of cisplatin active agents without compromising their anticancer activity. Also provided are methods for use in practicing the subject methods in the treatment of different disease conditions.

Several gastrointestinal and gynecological malignancies have the potential to disseminate and grow in the peritoneal cavity. The occurrence of peritoneal carcinomatosis (PC) has been shown to significantly decrease overall survival in patients. Treatment of residual microscopic disease remains a challenge with new anticancer modalities development. Now, the inventors propose an innovative therapeutic management of peritoneal carcinomatosis (PC) that is bio-inspired and tumor-targeted by engineering MSC-derived EVs to encapsulate a photosensitizer (mTHPC) for improved photodynamic therapy efficiency and safety. In this work, the inventors first evaluated the biodistribution of EVs-mTHPC in a murine PC model and highlighted superior accumulation of mTHPC in the tumor compared to other mTHPC formulations (free drug and liposomal one (Foslip®). The effectiveness of PDT mediated by mTHPC vectorized in EVs has then been evaluated in PC. In accordance with pharmacokinetics, the results revealed both an enhanced light-induced therapeutic efficiency in terms of tumoral cytotoxicity, safety for surrounding tissue after laser irradiation, immunomodulation and improved survival time. Thus, the present invention relates to mesenchymal stem cell derived extracellular vesicles loaded with at least one photosensitizer and uses thereof for the treatment of peritoneal carcinomatosis.

The present invention relates to a pharmaceutical composition for preventing or treating fibrosis, containing a pheophorbide compound as an active ingredient. The pharmaceutical composition can effectively inhibit fibrosis of tissues by inhibiting signaling of TGF-β which causes fibrosis and inhibiting activation and expression of collagen and fibronectin, and is significantly superior in the anti-fibrotic activity compared to nintedanib or pirfenidone, which are commercially available therapeutic agents for pulmonary fibrosis, and therefore may be widely used in the prevention or treatment of fibrosis.
