Independent DMPK consultant: expert support from discovery to Phase I
Independent drug metabolism, pharmacokinetics and drug–drug interaction consultancy from Guy Webber, BSc (Hons), MSc. 30+ years across pharma, biotech and CROs.

Value adding decisions that move your asset forward
I help biotech and pharma teams make strategic, asset-progressing and value-adding decisions using crucial DMPK information. This includes early de-risking analysis, identifying metabolic and DDI liabilities early to aid lead optimisation and candidate selection. Once the lead is selected, I can efficiently design the appropriate study package to progress through IND and CTA for entry into Phase I.
I can work either as an embedded member of your project team, or as an external remote adviser by the hour.
