Training Seminar: Applying Pharmacology to New Drug Discovery

Over the past 6 six years, the primary cause of new drug candidate failures (50%) has been failure of therapeutic efficacy. Put another way, drug discovery programs do everything right, get the defined candidate molecule, only to have it fail in therapeutic trials. Among the most prevalent reasons proposed for this shortcoming is the lack of translation of in vitro and recombinant drug activity to therapeutic in vivo whole systems. Drug activity in complete systems can be characterized with the application of pharmacological principles which translate drug behaviors in various organs with molecular scales of affinity and efficacy.

Pharmacological techniques are unique in that they can convert descriptive data (what we see, potency, activity in a given system) to predictive data (molecular scales of activity that can be used to predict activity in all systems including the therapeutic one, i.e. affinity, efficacy). The predicted outcome of this process is a far lower failure rate as molecules are progressed toward clinical testing.

This course will describe pharmacological principles and procedures to quantify affinity, efficacy, biased signaling and allostery to better screen for new drugs and characterize drug candidates in lead optimization assays. In particular, new concepts that have entered the fabric of discovery over the past few years, namely biased signaling and allosteric drug function, will be emphasized as new ways forward to reduce new candidate attrition in the drug discovery process.

      4. Inverse Agonism
      5. Allosteric Modulation, PAMs, NAMs, Screening for Allosterics
      6. Candidate Selection: Real Time Kinetics and in vivo Target Coverage

Day 2 PM: Drug Development

Training Seminar Information
Each CHI Training Seminar offers 1.5 days of instruction with start and stop times for each day shown above and on the Event-at-a-Glance published in the onsite Program & Event Guide. Training Seminars will include morning and afternoon refreshment breaks, as applicable, and lunch will be provided to all registered attendees on the full day of the class.

Each person registered specifically for the training seminar will be provided with a hard copy handbook for the seminar in which they are registered. A limited number of additional handbooks will be available for other delegates who wish to attend the seminar, but after these have been distributed, no additional books will be available.

Though CHI encourages track hopping between conference programs, we ask that Training Seminars not be disturbed once they have begun. In the interest of maintaining the highest quality learning environment for Training Seminar attendees, and because Seminars are conducted differently than conference programming, we ask that attendees commit to attending the entire program, and not engage in track hopping, as to not disturb the hands-on style instruction being offered to the other participants.
