Antibody Drugs

An antibody drug is a drug that utilizes an antibody that exists in a living body. By selectively binding to target molecules (antigens), antibody drugs perform various pharmacological effects.

The antibody drug market is expected to exceed 14 trillion yen in 2020, and “fully human antibodies”, which are expected to have higher efficacy and safety in the future, have become the mainstream of antibody drugs.

In the future, with the aging of companion animals (dogs and cats), it is expected that the market for complete dog/cat antibodies, which are more effective and safer for pets, will increase.
