Sustained Virological Response (SVR), or Viral Cure - A term used when a patient’s
HCV RNA remains undetectable six months after stopping treatment. SVR is also
known as viral cure.
Rapid Virological Response (RVR) -Measure of treatment response at week 4.
Indicated by undetectable HCV RNA (confirmed by HCV PCR) after 4 weeks of
treatment. Reaching RVR predicts a higher likelihood of SVR (viral cure).
Extended Rapid Virological Response (eRVR) - occurs when a patient has
undetectable HCV RNA at weeks 4 and 12.
Early Virological Response (EVR) - Measurement of response to hepatitis C
treatment at week 12. Occurs when HCV RNA cannot be detected in a patient’s
blood or decreases by more than 2 log (100 times) from the starting level by week
12.

Genotype - The genetic make-up of an organism or a virus. HCV has six genotypes
and many subtypes. A person’s HCV genotype may be important in determining
the severity of the disease and predicting response to treatment.
CD4 Count - A laboratory test that measures the number of CD4 T lymphocytes
(CD4 cells) in a sample of blood. In people with HIV, the CD4 count is the most
important laboratory indicator of immune function and the strongest predictor of
HIV progression. The CD4 count is one of the factors used to determine when to
start antiretroviral therapy (ART). The CD4 count is also used to monitor response
to ART.

Dosing considerations
•
Screening patients with HCV genotype 1a infection for the presence of
virus with the NS3 Q80K polymorphism at baseline is strongly
recommended (will be paid for by the company)
Alternative therapy should be considered for patients infected with HCV
genotype 1a containing the Q80K polymorphism
Must be taken with food as a whole tablet, daily.

Stopping Rules
HCV RNA
Action
Treatment week 4: ≥ Discontinue Simeprevir, peginterferon alfa and
25 IU/ml
ribavirin
Treatment week 12:
detectable1
Discontinue peginterferon alfa and ribavirin
(treatment with Simeprevir is complete at week 12)
Treatment week 24:
detectable1
Discontinue peginterferon alfa and ribavirin

Re-evaluation of HCV RNA is recommended in case of detectable HCV RNA after previous
undetectable HCV RNA to confirm HCV RNA levels prior to discontinuing HCV treatment.

HCV/HIV co-infection
• The safety and efficacy of Daklinza in the treatment
of HCV infection in patients who are co-infected with
HIV have not been established.
11
12/12/2014
Recommended regimens and treatment duration for Daklinza
•
G1 or 4, without cirrhosis - Daklinza + sofosbuvir - 12 weeks
•
G1 or 4, with compensated cirrhosis - Daklinza + sofosbuvir - 24 weeks
•
G3, with compensated cirrhosis and/or treatment experienced - Daklinza +
sofosbuvir + ribavirin – 24 weeks
•
G4, 24 weeks of Daklinza in combination with 24-48 weeks of peginterferon alfa
and ribavirin.
Interactions and dose recommendations
•
Coadministration of Daklinza with carbamazepine, oxcarbazepine,
phenobarbital, phenytoin, rifampicin, rifabutin, rifapentine, systemic
dexamethasone, St. John's wort or other strong inducers of CYP3A4 is
contraindicated.
•
An oral contraceptive containing ethinylestradiol 35 μg and norgestimate
0.180/0.215/0.250 mg is recommended with Daklinza. Other oral
contraceptives have not been studied.
•
It is not known whether daclatasvir is excreted in human milk. Available
pharmacokinetic and toxicological data in animals have shown excretion of
daclatasvir and metabolites in milk. A risk to the newborn/infant cannot
be excluded. Mothers should be instructed not to breastfeed if they are
taking Daklinza.
12
12/12/2014
Interactions and dose recommendations
•
The dose of Daklinza should be reduced to 30 mg once daily when
coadministered with atazanavir/ritonavir or other strong inhibitors of
CYP3A4
•
Due to the lack of data, coadministration of Daklinza and darunavir or
lopinavir is not recommended.
•
The dose of Daklinza should be increased to 90 mg once daily when
coadministered with efavirenz.
•
Due to the lack of data, coadministration of Daklinza and etravirine or
nevirapine is not recommended.
•
The dose of Daklinza should be reduced to 30 mg once daily when
coadministered with cobicistat or other strong inhibitors of CYP3A4.

Reviewing written materials with each patient and describing technical terms that may be used so
that the patient does not find him/herself in an uncomfortable situation where literacy deficits have
to be revealed.
Providing patients with pictorial or verbal information, and with models or diagrams to
supplement written materials. Displaying materials in both private and public areas creates a safe
space for a person to view the materials and may prompt a person to speak with a clinician about
the issues raised in the printed material.
Words, figures or pictures which should represent the exact number of pills a person is taking and
should correspond to the appropriate dose. Similarly indicate when & how the medication is to be
taken (e.g., symbol for morning for A.M. dose and symbol for food when medication is required to
be taken with food).
Use of medication aids e.g. pill boxes, SMS text services, alarms

•
Discussing possible side effects (e.g., potential drug and food interactions)
prior to a person beginning a particular medication and concentrating
efforts to plan for and to manage side effects at times when a new drug or
regimen is being started and thus medication side effects are most likely
to occur. Giving prompt attention to medication problems.
Initiating a discussion regarding an individual’s side effects can assist
those who may be hesitant to address such issues, especially when the
subjects are perceived as embarrassing or socially unacceptable.
Referring to peer educators and/or group meetings as good sources for
individuals to share practical management tips.
