Oportuzumab monatox is an experimental anti-cancer medication. Chemically, oportuzumab is a single chain variable fragment of a monoclonal antibody which binds to epithelial cell adhesion molecule (EpCAM, the tumor-associated calcium signal transducer 1). Oportuzumab is fused with Pseudomonas aeruginosa exotoxin A (which is reflected by the monatox in the medication's name).[1]
The drug was developed by Canadian-based Viventia Bio Inc. The company was acquired by Cambridge(MA)-based Eleven Biotherapeutics in 2016, which then changed its name to Sesen Bio.[2] In 2019 Sesen Bio reported updated, preliminary primary and secondary endpoint data from the company's Phase 3 VISTA trial further supporting the strong benefit-risk profile of Vicineum for the potential treatment of patients with high-risk, bacillus Calmette-Guérin(BCG) unresponsive, non-muscle invasive bladder cancer (NMIBC).[3] The Company applied for approval of Vicineum by the United States Food and Drug Administration and the European Medicines Agency.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
