ViiV Healthcare announces label update
for its long-acting HIV treatment, Cabenuva (cabotegravir, rilpivirine), to be
initiated with or without an oral lead-in
period
US FDA approval of updated label streamlines the initiation process
for the first and only complete long-acting HIV treatment by
allowing people to start directly with injections
London, 24 March 2022 -
ViiV Healthcare, the global specialist HIV company majority owned
by GlaxoSmithKline plc ("GSK"), with Pfizer Inc. and Shionogi
Limited as shareholders, today announced that the US Food and Drug
Administration (FDA) approved a label update
for Cabenuva (cabotegravir, rilpivirine) making the oral
lead-in with cabotegravir and rilpivirine tablets optional. Oral
cabotegravir and rilpivirine can be taken for a month to assess
tolerability to the medicines prior to initiating cabotegravir and
rilpivirine injections, a
regimen co-developed as part of a collaboration with the Janssen
Pharmaceutical Companies of Johnson & Johnson, but this
oral lead-in is now
optional after clinical trial data demonstrated similar safety and
efficacy profiles for both initiation methods (with or without the
oral lead-in).1,
2
Cabenuva is the first and
only complete long-acting HIV treatment regimen and is approved in
the US as a once-monthly or every-two-month treatment for HIV-1 in
virologically suppressed adults.1 It
contains ViiV Healthcare's cabotegravir extended-release injectable
suspension in a single-dose vial and rilpivirine extended-release
injectable suspension in a single-dose vial, a product of Janssen
Sciences Ireland Unlimited Company, one of the Janssen
Pharmaceutical Companies of Johnson &
Johnson.
Lynn Baxter, Head of North America at ViiV Healthcare,
said: "Since
launching Cabenuva, we have been keenly focused on optimising the
user experience for both people living with HIV and healthcare
providers. Today's label update for the optional oral lead-in
provides a streamlined initiation process for the regimen by
allowing people to start directly on long-acting injections and
underscores ViiV Healthcare's ongoing commitment to providing
innovative treatment options that address the evolving needs of the
HIV community."
This US FDA approval is based on the FLAIR phase III trial Week-124
results, which showed there were similar outcomes regarding
maintenance of virologic suppression, safety, tolerability and
pharmacokinetics in people starting cabotegravir and rilpivirine
injections with or without the oral
lead-in. 2
About Cabenuva (cabotegravir,
rilpivirine)
Cabenuva is indicated as a
complete regimen for the treatment of HIV-1 infection in adults to
replace the current antiretroviral regimen in those who are
virologically suppressed (HIV-1 RNA <50 c/ml) on a stable
antiretroviral regimen with no history of treatment failure and
with no known or suspected resistance to either cabotegravir or
rilpivirine.
The complete regimen combines the integrase strand transfer
inhibitor (INSTI) cabotegravir, developed by ViiV Healthcare, with
rilpivirine, a non-nucleoside reverse transcriptase inhibitor
(NNRTI) developed by Janssen Sciences Ireland Unlimited
Company. Rilpivirine is approved in the US as a 25mg tablet taken
once a day to treat HIV-1 in combination with other antiretroviral
agents in antiretroviral treatment-naïve patients 12 years of
age and older and weighing at least 35kg with a viral load
≤100,000 HIV RNA c/ml.
INSTIs inhibit HIV replication by preventing the viral DNA from
integrating into the genetic material of human immune cells
(T-cells). This step is essential in the HIV replication cycle and
is also responsible for establishing chronic disease. Rilpivirine
is an NNRTI that works by interfering with an enzyme called reverse
transcriptase, which stops the virus from multiplying.
Trademarks are owned by or licensed to the ViiV Healthcare group of
companies.
Important Safety Information
for Cabenuva (cabotegravir 200mg/mL; rilpivirine
300mg/mL) extended-release injectable suspensions
Cabenuva is indicated as a
complete regimen for the treatment of human immunodeficiency virus
type 1 (HIV-1) infection in adults to replace the current
antiretroviral regimen in those who are virologically suppressed
(HIV-1 RNA less than 50 copies per ml) on a stable antiretroviral
regimen with no history of treatment failure and with no known or
suspected resistance to either cabotegravir or
rilpivirine.
CONTRAINDICATIONS
●
Do not use Cabenuva in patients with previous hypersensitivity
reaction to cabotegravir or rilpivirine
●
Do not use Cabenuva in patients receiving carbamazepine,
oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifampin,
rifapentine, systemic dexamethasone (>1 dose), and St John's
wort
WARNINGS AND PRECAUTIONS
Hypersensitivity Reactions:
● Hypersensitivity reactions, including cases of
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have
been reported during postmarketing experience with
rilpivirine-containing regimens. While some skin reactions were
accompanied by constitutional symptoms such as fever, other skin
reactions were associated with organ dysfunctions, including
elevations in hepatic serum biochemistries
● Serious or severe hypersensitivity reactions have
been reported in association with other integrase inhibitors and
could occur with Cabenuva
● Discontinue Cabenuva immediately if signs or symptoms of
hypersensitivity reactions develop. Clinical status, including
liver transaminases, should be monitored and appropriate therapy
initiated. Prescribe the oral lead-in prior to administration
of Cabenuva to help identify patients who may be at risk
of a hypersensitivity reaction
Post-Injection Reactions:
● Serious post-injection reactions (reported in less
than 1% of subjects) were reported within minutes after the
injection of rilpivirine, including dyspnea, bronchospasm,
agitation, abdominal cramping, rash/urticaria, dizziness, flushing,
sweating, oral numbness, changes in blood pressure, and pain (e.g.,
back and chest). These events may have been associated with
inadvertent (partial) intravenous administration and began to
resolve within a few minutes after the
injection
● Carefully follow the Instructions for Use when
preparing and administering Cabenuva. The suspensions should be injected slowly via
intramuscular injection and avoid accidental intravenous
administration. Observe patients briefly (approximately 10 minutes)
after the injection. If a post-injection reaction occurs, monitor
and treat as clinically indicated
Hepatotoxicity:
●
Hepatotoxicity has been reported in
patients receiving cabotegravir or rilpivirine with or without
known pre-existing hepatic disease or identifiable risk
factors
●
Patients with underlying liver disease
or marked elevations in transaminases prior to treatment may be at
increased risk for worsening or development of transaminase
elevations
●
Monitoring of liver chemistries is
recommended and treatment with Cabenuva should be discontinued if hepatotoxicity is
suspected
Depressive Disorders:
●
Depressive disorders (including
depressed mood, depression, major depression, mood altered, mood
swings, dysphoria, negative thoughts, suicidal ideation or attempt)
have been reported with Cabenuva or the individual
products
●
Promptly evaluate patients with
depressive symptoms
Risk of Adverse Reactions or Loss of Virologic Response Due to Drug
Interactions:
●
The concomitant use
of Cabenuva and other drugs may result in known or
potentially significant drug interactions (see Contraindications
and Drug Interactions)
●
Rilpivirine doses 3 and 12 times
higher than the recommended oral dosage can prolong the QTc
interval
●
Cabenuva should be used with caution in combination
with drugs with a known risk of Torsade de
Pointes
Long-Acting Properties and Potential
Associated Risks with Cabenuva:
● Residual concentrations of cabotegravir and
rilpivirine may remain in the systemic circulation of patients for
prolonged periods (up to 12 months or longer). Select appropriate
patients who agree to the required monthly or every-2-month
injection dosing schedule because non-adherence could lead to loss
of virologic response and development of
resistance
● To minimize the potential risk of developing viral
resistance, it is essential to initiate an alternative, fully
suppressive antiretroviral regimen no later than 1 month after the
final injection doses of Cabenuva when dosed monthly and no later than 2
months after the final injections of Cabenuva when dosed every 2 months. If virologic
failure is suspected, switch the patient to an alternative regimen
as soon as possible
ADVERSE REACTIONS
● The most common adverse reactions (incidence
≥2%, all grades) with Cabenuva were injection site reactions, pyrexia,
fatigue, headache, musculoskeletal pain, nausea, sleep disorders,
dizziness, and rash
DRUG INTERACTIONS
●
Refer to the applicable
full Prescribing Information for important drug interactions
with Cabenuva, VOCABRIA, or EDURANT
●
Because Cabenuva is a complete regimen, coadministration with
other antiretroviral medications for the treatment of HIV-1
infection is not recommended
●
Drugs that are strong
inducers of UGT1A1 or 1A9 are expected to decrease the plasma
concentrations of cabotegravir. Drugs that induce or inhibit CYP3A
may affect the plasma concentrations of
rilpivirine
●
Cabenuva should be used with caution in combination
with drugs with a known risk of Torsade de
Pointes
USE IN SPECIFIC POPULATIONS
●
Pregnancy: There are insufficient human data on the use
of Cabenuva during pregnancy to adequately assess a
drug-associated risk for birth defects and miscarriage. Discuss the
benefit-risk of using Cabenuva during pregnancy and conception and consider
that cabotegravir and rilpivirine are detected in systemic
circulation for up to 12 months or longer after discontinuing
injections of Cabenuva. An Antiretroviral Pregnancy Registry has been
established
●
Lactation: The CDC recommends that HIV 1−infected
mothers in the United States not breastfeed their infants to avoid
risking postnatal transmission of HIV-1 infection. Breastfeeding is
also not recommended due to the potential for developing viral
resistance in HIV-positive infants, adverse reactions in a
breastfed infant, and detectable cabotegravir and rilpivirine
concentrations in systemic circulation for up to 12 months or
longer after discontinuing injections of Cabenuva
Please see full Prescribing
Information.
