concomitant use of ARVs

Key to Symbols

These drugs should not be

coadministered

Potential interaction- may

require close monitoring,

alteration of drug dosage or

timing of administration

No clinically significant

interaction expected

Filled symbols indicate further information

is available at www.hep-

druginteractions.org. Empty symbols

indicate the interaction has not been

assessed (either by study or within product

label) and has been predicted based on the

metabolic profiles of the drugs.

If a drug is not listed it cannot

automatically be assumed it is

well tolerated in co-

administeration.

• Networks of MSM who:

– Practice HIV serosorting

leading to unprotected sex

– Have high-risk sex practices

leading to blood exposure

– Use stimulant drugs leading to

sexual disinhibition and

prolonged sexual activity

Study Design

• Patients with chronic HIV and acute HCV infection – HCV GT 1 or 4

– ART consistent with LDV/SOF co-administration with HIV <200 copies/mL or not receiving ART with no plans to start

• Acute HCV infection with detectable HCV RNA (Roche COBAS® AmpliPrep/COBAS® TaqMan® version 2.0, LLOQ=15 IU/mL) for <24 weeks, defined by

– HCV RNA-positive and negative anti-HCV antibody/HCV RNA test within last 6 months or

– Elevated ALT/AST >2.5 x ULN in past 6 months with normal LFTs in past year, and other causes excluded

• 5 sites in Germany and UK

PARTNERS study

• 500 HCV infected individuals

• Monogamous heterosexual relationship for 15 years

• 20 partners HCV infected (4%)

• 9 couples had concordant genotype/serotype

• Viral isolates in three couples (0.6%) were highly related, consistent with

transmission of virus within the couple

• Based on 8,377 person-years of follow-up, the maximum incidence rate of

HCV transmission by sex was 0.07% per year (95% confidence interval, 0.01-

0.13) or approximately one per 190,000 sexual contacts
