, through its research unit Neusentis, seeks to collaborate with leading academic and biotechnology companies in Asia who have novel methodologies that can be used in vivo to determine if small molecule drug candidates have engaged selectively with their ion channel target at the intended site of action.
Although Pfizer is specifically interested in ion channel targets involved in pain signalling, the ability to measure engagement with ion channel targets for other therapeutic indications may also be considered.
Key Success Criteria:
Successful proposals must:
Drugs that engage with and modulate ion channel function are important therapeutics for treatment of human cardiovascular disorders (angina, hypertension and cardiac arrhythmias), metabolic dysfunction (type II diabetes), and neurological disorders (pain and epilepsy). Pfizer believes that the development of new medicines that target ion channels would be considerably less challenging if it were possible to readily demonstrate/ measure the engagement of the drug candidate with its ion channel target in vivo during clinical trials.
Pfizer is a global leader in pain medicines with products in each of the major classes. Neusentis, our research unit based in Cambridge UK and Research Triangle Park, North Carolina, USA, is focused on discovering new drugs that modulate ion channels as potential therapeutics for pain and sensory disorders. Although PET imaging studies can demonstrate direct engagement of many drugs to many targets, PET is largely unsuccessful when applied to ion channel drugs.
Neusentis is developing therapeutics that target ion channels expressed in peripheral and central nervous systems (including sensory neurones and the dorsal horn of the spinal cord).
Neusentis would be particularly interested in in vivo methodologies that quantify the engagement of candidate therapeutic agents with their ion channel targets in these tissue regions.
Approaches Not of Interest:
Methodologies that measure a functional consequence of a stimulus (i.e., the perception of pain measured on a pain scale or a quantitative physiological response to pain fiber activation) are not of interest. Rather, we are seeking direct biophysical evidence of ligand engagement with the target channel.
In developing responses to this Need, please keep in mind that the following list of potential solutions related to pain drug candidates have previously been considered and rejected, due to key limitations. Submitted solutions that include these methodologies will only be considered if evidence is provided describing how these limitations can be overcome.
