What are some clinical considerations around viral suppression to keep in mind when managing patients with HIV-1?

Please See

Indication and Selected Safety Information Below

  • Indication and Selected Safety Information

    INDICATIONS AND USAGE
    PIFELTRO™ (doravirine) is indicated in combination with other antiretroviral (ARV) agents for the treatment of HIV-1 infection in adult patients with no prior ARV treatment history or to replace the current ARV regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable ARV regimen with no history of treatment failure and no known substitutions associated with resistance to doravirine.

    SELECTED SAFETY INFORMATION

    Contraindications
    PIFELTRO is contraindicated when co-administered with drugs that are strong cytochrome P450 (CYP)3A enzyme inducers (including the anticonvulsants carbamazepine, oxcarbazepine, phenobarbital, and phenytoin; the androgen receptor inhibitor enzalutamide; the antimycobacterials rifampin and rifapentine; the cytotoxic agent mitotane; and the herbal product St. John's wort (Hypericum perforatum)), as significant decreases in PIFELTRO plasma concentrations may occur, which may decrease the effectiveness of PIFELTRO.

    Warnings and Precautions
    Immune Reconstitution Syndrome
    Immune reconstitution syndrome can occur, including the occurrence of autoimmune disorders with variable time to onset, which may necessitate further evaluation and treatment.

    Drug Interactions
    Co-administration of PIFELTRO with efavirenz, etravirine, or nevirapine is not recommended.

    If PIFELTRO is co-administered with rifabutin, increase PIFELTRO dosage to one tablet twice daily (approximately 12 hours apart).

    Consult the full Prescribing Information prior to and during treatment for more information on potential drug-drug interactions.

    Adverse Reactions
    The most common adverse reactions with PIFELTRO (incidence >5%, all intensities) were nausea (7%), dizziness (7%), headache (6%), fatigue (6%), diarrhea (6%), abdominal pain (5%), and abnormal dreams (5%).

    By Week 96 in DRIVE-FORWARD, 2% of adult subjects in the PIFELTRO group and 3% in the DRV+r group had adverse events leading to discontinuation of study medication.

    By Week 96 in DRIVE-AHEAD, 3% of adult subjects in the DELSTRIGO™ (doravirine/3TC/TDF) group and 7% in the EFV/FTC/TDF group had adverse events leading to discontinuation of study medication.

    In DRIVE-FORWARD, mean changes from baseline at Week 48 in LDL-cholesterol (LDL-C) and non-HDL-cholesterol (non-HDL-C) were pre-specified. LDL-C: -4.6 mg/dL in the PIFELTRO group vs 9.5 mg/dL in the DRV+r group. Non-HDL-C: -5.4 mg/dL in the PIFELTRO group vs 13.7 mg/dL in the DRV+r group. The clinical benefits of these findings have not been demonstrated.

    In DRIVE-AHEAD, mean changes from baseline at Week 48 in LDL-C and non-HDL-C were pre-specified. LDL-C: -2.1 mg/dL in the DELSTRIGO group vs 8.3 mg/dL in the EFV/FTC/TDF group. Non-HDL-C: -4.1 mg/dL in the DELSTRIGO group vs 12.7 mg/dL in the EFV/FTC/TDF group. The clinical benefits of these findings have not been demonstrated.

    In DRIVE-SHIFT, mean changes from baseline at Week 48 in LDL-C and non-HDL-C were pre-specified. LDL-C: -16.3 mg/dL in the DELSTRIGO group vs -2.6 mg/dL in the PI + ritonavir group. Non-HDL-C: -24.8 mg/dL in the DELSTRIGO group vs -2.1 mg/dL in the PI + ritonavir group. The clinical benefits of these findings have not been demonstrated.

    In DRIVE-AHEAD, neuropsychiatric adverse events were reported in the three pre-specified categories of sleep disorders and disturbances, dizziness, and altered sensorium. Twelve percent of adult subjects in the DELSTRIGO group and 26% in the EFV/FTC/TDF group reported neuropsychiatric adverse events of sleep disorders and disturbances; 9% in the DELSTRIGO group and 37% in the EFV/FTC/TDF group reported dizziness; and 4% in the DELSTRIGO group and 8% in the EFV/FTC/TDF group reported altered sensorium.

    The safety of DELSTRIGO in virologically-suppressed adults was based on Week 48 data from subjects in the DRIVE-SHIFT trial. Overall, the safety profile in virologically-suppressed adult subjects was similar to that in subjects with no ARV treatment history.

    Pregnancy/Breastfeeding
    There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to PIFELTRO during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263.

    Mothers infected with HIV-1 should be instructed not to breastfeed if they are receiving PIFELTRO due to the potential for HIV-1 transmission.

    Before prescribing PIFELTROTM (doravirine), please read the accompanying 
    Prescribing Information.  
    The Patient Information also is available. 

  • Overview

    Prescribing Information | Patient Information

    Meet Daniel, a patient with HIV-1 who has taken antiretroviral therapy for about 4 years and is currently virologically suppressed. However, some clinical concerns can be identified in his presentation, and he struggles with adherence. So how can you increase the likelihood of maintaining viral suppression? Join Dr. Ricky Hsu, one of the National Medical Directors at the AIDS Healthcare Foundation, as he shares this patient case, some key clinical considerations, and data on doravirine as a treatment option for patients with HIV-1.
