What Are Biologics?

Biologics are medicines derived from living organisms using biotechnology. They include monoclonal antibodies, fusion proteins, cytokine inhibitors, and other large-molecule therapies. Unlike conventional small-molecule drugs, biologics target specific components of the immune system or disease pathways with remarkable precision. Clinical trials are expanding their use far beyond their original indications, testing new targets, biosimilar versions, and combination approaches.

Types of Biologics in Clinical Trials

Monoclonal Antibodies (mAbs)

Lab-made proteins that bind to specific targets in the body. Trials test new mAbs for cancer (checkpoint inhibitors), autoimmune disease (TNF/IL inhibitors), and infectious disease. Examples: infliximab, adalimumab, natalizumab.

Fusion Proteins

Combination molecules that link a receptor to an antibody fragment. Etanercept-type drugs that soak up inflammatory cytokines. Trials explore new targets and longer-acting versions.

Biosimilars

Highly similar versions of existing biologic drugs. Trials confirm equivalent safety and efficacy, enabling lower-cost access to proven biologic therapies once patents expire.

Cytokine Inhibitors

Drugs targeting specific inflammatory signalling molecules (IL-6, IL-17, IL-23, IL-4/13). Trials test these in conditions where earlier biologic classes have failed or for newly identified disease pathways.

Bispecific Antibodies

Engineered antibodies that bind two different targets simultaneously. Emerging in oncology (engaging T-cells near tumours) and immunology (dual pathway blockade). A rapidly growing trial area.

Co-Stimulatory Modulators

Biologics that enhance or suppress immune cell activation. Trials in autoimmune disease test T-cell co-stimulation blockade, while cancer trials explore co-stimulation enhancement to boost anti-tumour immunity.

FAQs About Biologics Trials

What are biologics and how do they differ from conventional drugs?
Biologics are medicines produced from living organisms using biotechnology. Unlike conventional drugs (small molecules made chemically), biologics are large, complex proteins such as monoclonal antibodies or fusion proteins. They target specific parts of the immune system or disease pathways with high precision, often resulting in fewer off-target effects than traditional treatments.
What conditions are biologics used to treat in clinical trials?
Biologics are studied in clinical trials for a wide range of conditions including autoimmune diseases (rheumatoid arthritis, psoriasis, Crohn's disease, ulcerative colitis, lupus), respiratory conditions (asthma, COPD), cancers (lymphoma, leukaemia, melanoma), neurological conditions (multiple sclerosis), and rare genetic disorders (haemophilia, sickle cell disease).
Are biosimilar clinical trials different from biologic trials?
Biosimilars are highly similar versions of already-approved biologic drugs. Clinical trials for biosimilars typically require less extensive testing than the original biologic because the safety profile is already established. These trials focus on confirming that the biosimilar produces equivalent results to the reference product, often at a lower cost.
How are biologics administered in clinical trials?
Most biologics are administered by injection (subcutaneous or intravenous) because they are proteins that would be broken down in the stomach if taken orally. Subcutaneous injections can often be self-administered at home, while intravenous infusions are given in hospital or clinic settings. Some trials are exploring new delivery methods including auto-injectors and longer-acting formulations.
