Advancing the science of drug innovation

Successful drug innovation grows from a deep appreciation of disease pathophysiology and ingenuity in fine-tuning the pharmacologic properties of promising disease-modifying agents.

Nektar is the global leader in polymer chemistry — a powerful approach to drug design that focuses on creating new molecular entities with optimized drug pharmacology. Our success is rooted in two key strategies. The first is targeting well-characterized biomolecular pathways considered likely to yield significant therapeutic benefits. And the second is exploiting the structural malleability of polymers — key chemical building blocks that provide a near-limitless toolbox with which to customize the behavior of a new molecule.

Our unique methodology has led to an impressive record of clinical and commercial successes, which we invite you to explore Approved Products and Product Pipeline.

Defining the science of polymer conjugation

We call our approach to new drug development "smart pharmacology."

Our chemistry is being used to control pharmacokinetics, biodistribution, receptor selectivity, and other important properties with high precision. Simply put: smart pharmacology hits the right target in the right place in the body at the right time.

Nektar chemists and molecular engineers shape the behavior of polymer drug conjugates by carefully selecting the architecture, composition, and size of the polymer, and by identifying the right location and chemistry of the linker molecules that bind it to the active agent. The polymer component within the new molecule influences the PK, biodistribution and selectivity of the composite molecule, without compromising the biological action on the target receptors.

With our proprietary platform, a broad range of valuable functional attributes become accessible to new drugs. For example, we have developed methods to:

  • Target tumor tissue more effectively
  • Modulate entry of molecules into the CNS
  • Design peripherally-acting drugs which do not enter the CNS
  • Tune receptor selectivity to achieve the proper balance of drug action
  • Design new drugs with oral bioavailability in areas where this was not possible in the past
  • Significantly prolong drug circulation time to extend the duration of a drug's activity
