Information on the AbbVie Care Pharmacy Programme
•
This VIEKIRA PAK and VIEKIRA PAK-RBV QUM (Quality of Use Medicine) module is
designed to support Pharmacists who wish to register with AbbVie to become an
AbbVie Care Pharmacy.
•
The distribution mechanism for Hepatitis C medicines is similar to that used by
PHARMAC for a number of other high-cost funded medicines.
Under this Xpharm mechanism, the pharmacy does NOT purchase the medicine
and pharmacies cannot claim a dispensing fee.
•
The AbbVie Care Pharmacy Programme is sponsored by AbbVie Limited, the
manufacturer of VIEKIRA PAK and VIEKIRA PAK-RBV.
Information on the AbbVie Care Pharmacy Programme
continued..
•
Only pharmacies enrolled in the AbbVie Care Pharmacy Programme can dispense the
medicine.
•
There is a one-off payment of a fee-for-service of NZ$100 per patient for the 3 months
of dispensing provided (or if a patient is on a longer treatment course the Pharmacy is
paid a fee-for-service of NZ$200).
•
Payment will be made to the AbbVie Care pharmacy by Healthcare Logistics (HCL). The
patient does NOT pay for any pharmacy charges associated with accessing the
medicine.

•
Transmission through blood products pre-1992
•
Transmission through injecting drug use
•
There are 6 genotypes (GT1-6)
•
Genotype 1 is the most common at 56%
There are 2 sub-types:
VIEKIRA PAK and
VIEKIRA PAK-RBV are
indicated in genotype 1

AbbVie Limited. VIEKIRA PAK and VIEKIRA PAK-RBV Data Sheets. Medsafe New Zealand; Dec 2016.
A dosing card is completed, with the dose of ribavirin tablets (as
appropriate), and given to the patient with each dispensing
• Complete the section of the dosage card with the dose of
ribavirin (for patients on VIEKIRA PAK-RBV).
• Ask the patient to make a note of how many VIEKIRA PAK tablets and ribavirin tablets they
have left when they come to collect their repeat script.
This will allow you to assess their adherence and reinforce its importance to
provide the best chance of achieving a cure (SVR12).
While the patient will have unused ribavirin tablets each month if the daily dose
is <1,200 mg, any leftover VIEKIRA PAK should prompt a discussion on adherence.
• Any unused medicine should be returned to the pharmacy for safe disposal.
Missed Doses – advice for patients
Missed dose of PTV/r/OBV* (OD dosing)
• ≤12 hours: take the prescribed dose
• >12 hours: do NOT take the missed dose; take the next dose as usual, with food
Missed dose of DSV** (BD Dosing)
• ≤6 hours: take the prescribed dose
• >6 hours: do NOT take the missed dose; take the next dose as usual, with food
Missed dose of RBV (BD Dosing)
• Do NOT take the missed dose; take the next dose as usual, with food
Patients should not take more than their prescribed dose of VIEKIRA PAK or VIEKIRA PAK-RBV
to make up a missed dose^
^A
missed dose should be reported as an adverse event; see slide 40 for how to report an AE. .

Contraindications for VIEKIRA PAK
• Severe hepatic impairment (Child-Pugh C)
• Co-administration with drugs that are highly dependent on CYP3A for hepatic
clearance, are moderate or strong inducers of CYP3A, or are strong inducers or
inhibitors of CYP2C8*
• Hypersensitivity to components or excipients
Additional contraindications for VIEKIRA PAK-RBV
• Pregnancy (including men whose partners are pregnant). [Category X]
Use two forms of contraception to avoid pregnancy, and for 6 months after
ribavirin is discontinued
•
History of severe, unstable, or uncontrolled cardiac disease in previous 6 months
• Haemoglobinopathies (e.g. thalassaemia, sickle-cell anaemia)
* For info on DDIs, refer to the
Data Sheets and www.hep-druginteractions.org; also see slide 31-32.
AbbVie Limited. VIEKIRA PAK and VIEKIRA PAK-RBV Data Sheets. Medsafe New Zealand; Dec 2016.
Precautions for VIEKIRA PAK
•
Not recommended for HCV genotypes other than 1
•
Not recommended in patients with Child-Pugh B hepatic impairment
•
Not recommended for co-administration with other HCV antivirals, or for patients
who have previously failed therapy with direct-acting antiviral agents
•
Safety & effectiveness in children younger than 18 and patients over 70 years of age
have not been established.
•
All patients should be tested for hepatitis B virus (HBV). People with a current or
previous HCV/HBV co-infection should be monitored for reactivation of HBV during
or after treatment for HCV. Concomitant therapy for hepatitis B may be required.
AbbVie Limited. VIEKIRA PAK and VIEKIRA PAK-RBV Data Sheets. Medsafe New Zealand; Dec 2016.
Additional precautions for VIEKIRA PAK-RBV
•
Use with caution and close monitoring in patients with pre-existing cardiac
disease or significant vascular disease (symptomatic ischaemic heart disease, recent transient
ischaemic attack , cerebrovascular accident, claudication); discontinue if cardiac function deteriorates
•
Ribavirin (RBV) can cause dose-related haemolysis and anaemia; haemoglobin
should be monitored and dose of RBV adjusted or discontinued as required (see next slide)
•
Discontinue RBV in case of an acute hypersensitivity reaction (e.g. urticaria,
angioedema, bronchoconstriction, or anaphylaxis)
•
Reduce starting doses of RBV in patients with renal impairment*
•
ribavirin and its metabolites are excreted renally
•
If creatinine clearance ≤50 mL/min, RBV should only be used if considered essential;
haemoglobin should be monitored intensively during treatment.
* Note: It is not necessary to adjust the dose of VIEKIRA PAK in patients with
mild, moderate or severe renal impairment.

Safety monitoring: Dose reduction of ribavirin for anaemia
during treatment
Laboratory values
Patients with no cardiac
disease
Patients with history of stable
cardiac disease
Reduce ribavirin dose to
600mg/day* if:
Discontinue† ribavirin if:
Haemoglobin < 100 g/l
Haemoglobin < 85 g/l
>20 g/L decrease in
haemoglobin during any 4week period during treatment
(permanent dose reduction)
Haemoglobin <120 g/L
despite 4 weeks at reduced
dose
* Patients whose dose of ribavirin is reduced to 600 mg daily should receive one
200mg tablet in the morning and two 200mg tablets in the evening.
† If the abnormality is reversed, ribavirin may be restarted at 600 mg daily, and
further increased to 800 mg at the discretion of the treating physician. However, a
return to higher doses is not recommended.
• In phase 3 clinical trials with VIEKIRA PAK-RBV, 8.5% of patients required
ribavirin dose reduction. Dose reduction did not affect efficacy.
AbbVie Limited. VIEKIRA PAK and VIEKIRA PAK-RBV Data Sheets. Medsafe New Zealand; Dec 2016.
Pregnancy, contraception and breastfeeding
•
VIEKIRA PAK is not recommended (Category B3); there is no safety data for use during
pregnancy or lactation
•
VIEKIRA PAK-RBV is contraindicated, including in men whose partners are pregnant;
ribavirin is teratogenic (Category X)
•
Patients should be counselled on the importance of avoiding pregnancy during treatment.
Reliable contraception is considered essential for women, and for men whose partners
could fall pregnant. Additionally, for those receiving ribavirin (VIEKIRA PAK-RBV), two forms
of contraception should be used (including a barrier method) to avoid pregnancy, during
treatment and for 6 months after treatment has finished
•
Check for DDIs that may affect contraception efficacy
•
Contraceptives containing ethinylestradiol should be avoided because of possible
hepatotoxicity (elevation of ALT) with VIEKIRA PAK. Women taking ethinylestradiolcontaining contraceptives should be switched to other effective contraceptives ≥2 weeks
prior to starting VIEKIRA PAK until ≥2 weeks after finishing treatment
•
Pharmacy staff of child-bearing age should use caution when handling ribavirin
•
Because of the potential for adverse events in nursing infants, breastfeeding must be
discontinued prior to initiation of treatment.

Overview: Drug–drug interactions
•
All direct-acting antivirals interact with drug metabolising enzymes or transporters.
Ribavirin is associated with additional drug interactions.
• VIEKIRA PAK undergoes hepatic metabolism. Interactions are primarily
mediated through CYP3A and P-glycoprotein inhibition.
•
All patients with hepatitis C should undergo a careful medicines review before
treatment.
•
Many drug interactions are not clinically relevant, or can be managed by
monitoring and /or dose adjustment. Others are contraindicated, and should be
stopped or switched to alternatives.
•
No dose adjustment is needed for VIEKIRA PAK itself.
•
During each patient dispensing discussion, ask the patient to tell you about any
other medicines they are taking, including recreational drugs and any remedies
they buy without a prescription from the pharmacy, supermarket or health food
store.
