Advancing Genetic Engineering
The growing advancements in genetic engineering are driving the demand for monoclonal antibodies. With its use, the antibody sequencing can be tailored, which in turn improves the therapeutic action, binding affinity, and safety of the mAbs. It is being used for the development of various antibody-drug-conjugates, biosimilars, and bispecific antibodies, which enhance the applications of mAbs. The stability and yield of the cell lines used for the development of mAbs are also enhanced with it. Thus, this drives the monoclonal antibodies market growth.
High Price
For the development of the mAbs, specialized facilities and equipment are required, which are costly. This increases their development cost. Similarly, the cost associated with the mAb products is also high, which makes it difficult for the patient to afford them. Moreover, the delay in the regulatory approval can also add to this cost. Thus, this can limit their adoption rates.
Growing Bispecific Antibody Treatment Approaches
The use of mAbs for the treatment of various chronic diseases is increasing. This, in turn, is increasing the demand for bispecific antibodies due to their dual targeting action. Therefore, the development of new bispecific antibody therapies for targeting cancer cells is increasing. It also helps in reducing the chances of resistance and the need for combination therapies. They are also being used for the treatment of infectious diseases, as they can help in neutralizing the viral strains. Thus, this is promoting the monoclonal antibodies market growth.
