BIOLOGICS /BIOLOGICALS The Other Side of Spectrum in the Age of CORONA

Biologics are made from a variety of natural sources—human, animal molecule drugs, some biologics are intended to treat diseases and medical conditions. Other biologics are used to prevent or diagnose disease. The biologics now in development make use of a range of new technologies to harness scientific progress, as follows:
● Monoclonal antibodies
● Vaccines, including therapeutic vaccines
● Blood and blood products for transfusion and/or manufacturing into other products
● Gene therapies
● Cell therapies
● Antisense Therapies
● Recombination Fusion Protein Therapy
● Stem Cell Therapies
● Tissue Engineering

Biosimilars,Biosuperiorsorthe original, innovative compound – are all complex treatments, they do not share the same regulatory pathway to approval orinvolve the same level of investment or risk.A first-in-class product has greatest riskasitrequiresidentifyinganew target,andsubsequently developingatherapeutic compoundforthattargetand validating the target mechanism for disease intervention in human. First-in-classbiologicssuchas monoclonalantibodiesuse advanced technologies such as recombinantDNA,and mammalianexpression techniques, and are very costly. It requiresmanufacturingfacilities with greater complexity than what is involved with small molecule drugs. And a very high cost for innovation which can be upto $1.2 billion.Biologicalsofferamore targetedapproachtocancer management.Theycanactby turning off pathogenic pathways, activate apoptosis signalling, or evendownregulatesignal pathways,thusofferingvarious options.
