Classical Example of DDI with

Harmful Clinical Consequences

October 17, 2018GMP 2018 - Institut Pasteur - Paris3

The first case of well documented DDI with

harmful clinical consequences was that of the

potentially lethal arrhythmia, torsades de pointes,

occurring in association with terfenadine

(Seldane) use in a young woman.

This ECG is a classic example of torsades de

pointes, which is French for "twisting of the

points“. Torsades is a form of ventricular

tachycardia that can most often be due to

medications. The QRS complexes during this

rhythm tend to show a series of "points up"

followed by "points down" often with a narrow

waist between. Recognition and reporting of this

arrhythmia in association with terfenadine,

astemizole (Hismanal), cisapride (Propulsid),

grepafloxacin (Raxar), and mibefradil (Posicor)

ultimately led to the removal of these medications

from the market.

Drug Transporters – Clinical

Relevance (1/2)

October 17, 2018GMP 2018 - Institut Pasteur - Paris9

Clinical relevance

• P-gp and BCRP limit

oral bioavailability of

drug substrates

• Inhibition of P-gp or

BCRP increased

substrate

bioavailability

• High gut

concentrations of

inhibitors lead to max.

transport inhibition

Hillgren KM et al. Clin Pharmacol Ther

2013;94:52-63

Clinical relevance

• P-gp (and BCRP)

constitute BBB for

substrate drugs

• Transport inhibition

potential CNS ADRs

• Unbound concentrations

of marketed inhibitors at

• Drugs with high

• Uptake inhibition may

US FDA approved drugs from 2013

to 2016 : PK DDIs in NDAs

October 17, 2018GMP 2018 - Institut Pasteur - Paris13

103 NDAs including 14 combination drugs

NMEs = 107

CYP3A = approximately 2/3 of all DDIs

Transporters (alone or with enzymes) = about 1/2 of all DDIs Weak-to-moderate interactions (as victims or penetrators)

Victims : 8 NMEs sensitive substrates of CYP3A4, 2 for CYP1A2, 1 for

CYP2C8, 1 for CYP2D6 1 NME = sensitive substrate of OATP1B1/3:

Grazoprevir with changes in exposure greater than 5-fold when co-

administered with a strong inhibitor 75% of identified CYP3A4 substrates were also substrates of P-gp

US FDA Approved Drugs from 2013

to 2016 : PK DDIs in NDAs (2/2)

October 17, 2018GMP 2018 - Institut Pasteur - Paris14

Penetrators :

Most clinical DDIs involved weak-to-moderate inhibition or

induction

Only 1 NME showed a strong inhibition of CYP3A and 1 NME

behaved as a strong CYP3A inducer

Among drugs with large changes in exposure (≥ 5-

fold), whether as victim or perpetrator, the most

represented classes were antivirals and oncology

drugs, suggestion a significant risk of clinical DDIs in

these patient populations.

US FDA Approved Drugs in 2017:

PK DDIs in NDAs

October 17, 2018GMP 2018 - Institut Pasteur - Paris15

46 drugs

34 NDAs including 3 combination drugs

9 cancer treatments and 8 anti-infective agents

All the NDAs were systematically evaluated for metabolism- and transport-mediated DDI and similar trends were observed compared with drugs approved 2013-2016

CYP3A was confirmed as the predominant enzyme responsible for clinically significant drug interactions involving both inhibition and induction

Inhibition of OATP1B1/1B3 is emerging as a significant mechanism of DDIs, leading to large changes in exposure of victim drugs (antivirals, statins)

In addition to clinical trials, PBPK simulations continue to develop at a clinical tool to support dose recommendations

Summary

October 17, 2018GMP 2018 - Institut Pasteur - Paris33

• Transported-mediated DDIs may have high clinical relevance

(toxicity or loss of efficacy), but their extent is rather lower than

DDIs mediated by metabolic enzymes

• Transported-mediated DDIs are significantly more complex than

DDIs mediated by metabolic enzymes

• Transporter-mediated intestinal absorption, hepatic uptake and

renal tubular secretion are main sites of transporter-mediated

DDIs

• Clinical relevance of transporter-mediated DDIs at BBB is still

unclear

• Genetic polymorphisms and disease states can also affect

transporters function

• Emerging data on newly characterized transporters may change

mechanistic understanding of clinically relevant DDIs

• Limitations of the in vitro assays and complexity of in vivo DDIs

(differential contribution of various enzyme and transporter)

• Tissue concentration variations can be much higher than plasma

exposure particularly in comparison with DDIs mediated by

metabolic enzymes

• In- silico methods have been used in drug development to inform

study design or labelling recommendations

Summary

October 17, 2018GMP 2018 - Institut Pasteur - Paris34

• Transporter-medicated DDIs are to be considered in drug

development as an integral part of risk assessment for the optimal

use in the intended patient population

• NMEs are recommended to be investigated as potential substrates

and/or inhibitors/inducers of relevant drug transporters according

to decision trees

• Results need to be reflected in drug labels in order to prevent

adverse drug reaction or lack of efficacy caused by transporter-

mediated DDIs

• Exposure to a clinically relevant DDI might warrant a change in

therapy, increased monitoring, and/or patient education

• Mitigate the risk of undesired clinical consequences in the presence

of concomitant medications

• Well refined PBPK modeling may enable optimal predictions of

transporter-mediated DDIs and help optimizing or even omitting

clinical trials

• Biomarkers may help elucidates the in vivo transporter in early

phase clinical studies

• No guidelines or standards for determining relevance of

interactions via consistent systematic evaluation or classification

• Clinical outcomes associated with the DDI must be determined,

including the magnitude in variability and frequency of effects
