Tibotec Pharmaceuticals Ltd's EDURANT(R) (rilpivirine) Receives Positive Opinion from CHMP for Use in Treatment-Naive Adults with HIV-1


9/23/2011 8:31:40 AM

TITUSVILLE, New Jersey, September 23, 2011 /PRNewswire/ --

- Third HIV medication submitted by Tibotec -

Tibotec Pharmaceuticals (Tibotec), one of the Janssen Pharmaceutical Companies, announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending the approval of EDURANT® (rilpivirine), a 25 mg tablet, as a once-daily treatment in combination with other antiretroviral agents (ARVs), for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in antiretroviral treatment-naïve adult patients with a viral load 100,000 HIV-1 RNA copies/mL. EDURANT is a medicinal product in the non-nucleoside reverse transcriptase inhibitor (NNRTI) class.

The CHMP positive opinion is a critical step in the approval process and will be considered by the European Commission, which has authority to approve medicines for use throughout the European Union. EDURANT was approved by the U.S. Food and Drug Administration (FDA) in May 2011 (see below for the U.S. indication and important safety information) and by the Canadian Health authorities (Health Canada) in July 2011. Applications for approval have also been submitted in other countries, including Switzerland and Australia.

The positive opinion is based on 48-week analyses of ECHO and THRIVE, two phase 3 clinical trials which evaluated the efficacy, safety and tolerability of EDURANT in treatment-naïve HIV-1 adult patients in over 20 countries. The 48-week analyses of both ECHO and THRIVE were published in the 16thJuly 2011 edition of the Lancet.[1,2]

"We are committed to developing new and innovative treatment options for HIV; EDURANT will offer a further option for patients who are starting HIV combination therapy for the first time," says Wim Parys, MD, Global Head, Infectious Diseases, Janssen. "We are encouraged by this positive opinion from the CHMP and will work closely with regulatory authorities to make EDURANT available to HIV patients in Europe."

EDURANT is also combined with Gilead's TRUVADA® (emtricitabine 200mg/tenofovir disoproxil fumarate 300mg) in a once-daily single-tablet regimen, which was submitted under a separate Marketing Authorisation Application (MAA) and is currently under assessment by the EMA. The fixed dose combination of EDURANT and TRUVADA was approved by the U.S. FDA in August 2011.

Parys added: "We are pleased to partner with Gilead, one of the leading companies in the fight against HIV/AIDS, which shares our dedication to improving treatment options for people living with HIV."

About EDURANT (rilpivirine)

EDURANT is an NNRTI, which blocks reverse transcriptase, a key enzyme that the HIV virus uses to replicate. The EMA regulatory application for EDURANT is based on the 48-week results of two pivotal Phase 3 double-blind, randomized studies known as ECHO (TMC278-C209) and THRIVE (TMC278-C215).[1,2]The studies evaluated the efficacy, safety and tolerability of once-daily EDURANT, in combination with two NRTIs, in treatment-naïve HIV-1-infected adults, and both achieved their primary objective of demonstrating non-inferiority of EDURANT vs. efavirenz in the percentage of patients achieving an undetectable viral load (less than 50 copies/mL) at week 48.[1,2]

U.S. Indication

EDURANT is indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in antiretroviral treatment-naïve adult patients.

This indication is based on Week 48 safety and efficacy analyses from two randomized, double-blinded, active controlled, Phase 3 trials in treatment-naïve patients and Week 96 safety and efficacy analyses from a Phase 2b trial in treatment-naïve patients.

The following points should be considered when initiating therapy with EDURANT:

  • More EDURANT treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure compared to subjects with HIV-1 RNA less than 100,000 copies/mL at the start of therapy.
  • The observed virologic failure rate in EDURANT treated subjects conferred a higher rate of overall treatment resistance and cross-resistance to the NNRTI class compared to efavirenz.
  • More subjects treated with EDURANT developed lamivudine/emtricitabine associated resistance compared to efavirenz.

    U.S. Important Safety Information
    Contraindications
 
    - Coadministration of EDURANT(TM) with the following drugs is
    contraindicated because significant decreases in rilpivirine plasma
    concentrations may occur due to CYP3A enzyme induction or gastric pH
    increase, which may result in loss of virologic response and possible
    resistance and cross-resistance: carbamazepine, oxcarbazepine,
    phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, proton pump
    inhibitors such as esomeprazole, lansoprazole, omeprazole, pantoprazole,
    and rabeprazole, systemic dexamethasone, and products containing St.
    John's wort (Hypericum perforatum)

    Warnings and Precautions
 
    - Depressive Disorders: Severe depressive disorders, defined as depressed
    mood, depression, dysphoria, major depression, mood altered, negative
    thoughts, suicide attempt, and suicidal ideation, have been reported with
    EDURANT(TM). Immediate medical evaluation is recommended for severe
    depressive symptoms
 
    - Fat Redistribution: Redistribution and/or accumulation of body fat have
    been observed in patients receiving antiretroviral (ARV) therapy. The
    causal relationship, mechanism, and long-term consequences of these events
    have not been established
 
    - Immune Reconstitution Syndrome has been reported in patients treated
    with combination ARV therapy, including EDURANT(TM)

    Drug Interactions
 
    - EDURANT(TM) should be used with caution when coadministered with drugs
    that may reduce the exposure of rilpivirine, such as antacids and
    H2-receptor antagonists
 
    - EDURANT(TM) should be used with caution when coadministered with a drug
    with a known risk of Torsade de Pointes
 
    - EDURANT(TM) should not be used in combination with NNRTIs
 
    This is not a complete list of potential drug interactions.
 
    Please see full Prescribing Information for more details.

    Use in Specific Populations
 
    - Hepatic Impairment: EDURANT(TM) should be used with caution in patients
    with severe hepatic impairment (Child-Pugh Class C) as pharmacokinetics of
    EDURANT(TM) have not been evaluated in these patients
 
    - Pregnancy Category B: EDURANT(TM) should be used during pregnancy only
    if the potential benefit justifies the potential risk. No adequate and
    well-controlled studies have been conducted in pregnant women

    Adverse Reactions
 
    - The most common adverse drug reactions reported (incidence >2%) of at
    least moderate intensity (Grade 2) in patients
    taking EDURANT(TM) through 48 weeks were depressive disorders (4%),
    insomnia (3%), headache (3%), and rash (3%)
