Market Definition
Therapeutic antibodies are targeted biopharmaceuticals that trigger a biological response. Therapeutic antibodies are drugs that use antibodies, which play a significant role in the body's innate immune system. Antibodies are produced by B cells, a type of immune cell, to attack foreign substances (antigens) in response to infections or allergens. Since antibodies recognize and attack only specific antigens, these properties are leveraged to generate genetically engineered antibodies (chimeric, humanized, fully human, engineered fragments & bispecific) designed to target and neutralize specific disease markers.
