The present invention provides antibodies useful as therapeutics for treating and/or preventing diseases associated with cells expressing CLD18, including tumor-related diseases such as gastric cancer, esophageal cancer, pancreatic cancer, lung cancer, ovarian cancer, colon cancer, hepatic cancer, head-neck cancer, and cancer of the gallbladder.

Single-domain antibodies that bind the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) spike protein are disclosed. The single-domain antibodies include binding domains that bind epitopes of the Spike ectodomain inside and outside the receptor binding domain. The single-domain antibodies can be used for multiple purposes including in the research, diagnosis, and prophylactic or therapeutic treatment of COVID-19.

The present invention provides antibodies useful as therapeutics for treating and/or preventing diseases associated with cells expressing CLD18, including tumor-related diseases such as gastric cancer, esophageal cancer, pancreatic cancer, lung cancer, ovarian cancer, colon cancer, hepatic cancer, head-neck cancer, and cancer of the gallbladder.

This invention relates to monospecific and multispecific antibodies that may be utilized for the diagnosis and treatment of various diseases. In addition, these antibodies may be modified by protease cleavage. Protease control or regulation may be provided by a protease site located in, for example, a linker. These protease-regulated antibodies may also be utilized for the diagnosis and treatment of various diseases.
