DESCOVY (emtricitabine 200mg/tenofovir alafenamide 25mg tablets) FOR PrEP (pre-exposure prophylaxis)
 
 

INDICATION

DESCOVY® for HIV-1 pre-exposure prophylaxis (PrEP) is indicated in at-risk adults and adolescents (≥35 kg) to reduce the risk of sexually acquired HIV-1 infection, excluding individuals at risk from receptive vaginal sex. HIV-1–negative status must be confirmed immediately prior to initiation.

Limitation of Use: DESCOVY FOR PrEP is not indicated in individuals at risk of HIV-1 from receptive vaginal sex because effectiveness in this population has not been evaluated.

IMPORTANT SAFETY INFORMATION
 
BOXED WARNING: RISK OF DRUG RESISTANCE WITH USE OF DESCOVY FOR PrEP IN UNDIAGNOSED EARLY HIV-1 INFECTION and POST TREATMENT ACUTE EXACERBATION OF HEPATITIS B
 
DESCOVY FOR PrEP must be prescribed only to patients confirmed to be HIV negative immediately prior to initiation and at least every 3 months during use. Drug-resistant HIV-1 variants have been identified with use of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) for HIV-1 PrEP following undetected acute HIV-1 infection. Do not initiate if signs or symptoms of acute HIV-1 infection are present unless HIV-negative status is confirmed
 
 
Severe acute exacerbations of hepatitis B have been reported in patients infected with hepatitis B virus (HBV) who discontinued products containing FTC and/or TDF, and may occur with discontinuation of DESCOVY. Closely monitor hepatic function with both clinical and laboratory follow-up for at least several months in patients with HBV who discontinue DESCOVY. If appropriate, anti-hepatitis B therapy may be warranted

Nearly all patients remained HIV-free with DESCOVY FOR PrEP1
 
DESCOVY FOR PrEP was noninferior to TRUVADA®
 
HIV incidence rate of 0.16/100 PY vs 0.34/100 PY (IRR=0.47; CI: 0.19-1.15)
 
99.7% of patients remained HIV-free at primary analysis* with DESCOVY (n=2670) vs 99.4% of patients with TRUVADA (n=2665)
 
For the subset of patients (17%) using TRUVADA at baseline:
 
100% of patients who switched to DESCOVY FOR PrEP (n=459) remained HIV-free vs 99.8% of those who continued using TRUVADA (n=438)2
 
 
 
Common adverse reactions were similar through primary analysis1*
 
The most common adverse reactions in patients who received DESCOVY (n=2694) and TRUVADA (n=2693) (incidence ≥2%, all grades) were diarrhea 5% and 6%, nausea 4% and 5%, headache 2% and 2%, fatigue 2% and 3%, and abdominal pain 2% and 3%, respectively.
 
*When 100% of patients reached Week 48 and ≥50% reached Week 96.
 
The DISCOVER Trial Design1,3
 
The efficacy and safety of DESCOVY to reduce the risk of acquiring HIV-1 infection were evaluated in the randomized, double-blind DISCOVER Trial comparing DESCOVY (n=2670 for efficacy; n=2694 for safety) with TRUVADA (n=2665 for efficacy; n=2693 for safety). HIV-seronegative men and transgender women who have sex with men, who were at risk of HIV-1 infection and reported condomless anal sex with ≥2 partners in the prior 12 weeks, or who had syphilis or rectal gonorrhea or chlamydia in the prior 24 weeks, were randomized 1:1 to receive once-daily, blinded, active tablets of DESCOVY or TRUVADA with matching placebos. The primary endpoint was the incidence of documented HIV-1 infection per 100 PY (primary analysis occurred with a minimum follow-up of 48 weeks and at least 50% of patients having 96 weeks of follow-up).
 
Switch subset1
 
In the study population, a subset of 17% of patients (n=905) were using TRUVADA at baseline. Of these patients, 465 were randomized to DESCOVY and 440 were randomized to continue using TRUVADA.
 
Less impact on markers of renal function1,2
 
Renal function chart graphic
 
There was a 4.1-mL/min difference between DESCOVY FOR PrEP
(+1.8 mL/min) and TRUVADA (-2.3 mL/min) in eGFRCG at Week 48.
 
 
Baseline:
122.9 mL/min
 
 
Baseline:
121.2 mL/min
 
 
The long-term clinical significance of changes in eGFR is not known.
 
Lower serum creatinine levels were also seen with DESCOVY FOR PrEP at Week 48
 
Mean serum creatinine decreased 0.01 mg/dL with DESCOVY FOR PrEP vs a 0.01-mg/dL increase with TRUVADA from baseline1
 
 
Important Safety Information (cont'd)
 
Warnings and precautions
 
New onset or worsening renal impairment: Cases of acute renal failure and Fanconi syndrome have been reported with the use of tenofovir prodrugs. Do not initiate DESCOVY in patients with estimated creatinine clearance (CrCl) <30 mL/min. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue DESCOVY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Monitor renal function in all patients (see Dosage and Administration section)

There was a 4.5-mL/min difference between DESCOVY FOR PrEP
(+3.9 mL/min) and TRUVADA (-0.6 mL/min) in eGFRCG at Week 48.
 
 
Baseline:
118.8 mL/min
 
 
Baseline:
116.7 mL/min
 
 
Significantly less impact on BMD1,3
 
Mean % change in lumbar spine and hip BMD at Week 48
Week 48 Lumbar spine/Hip BMD chart graphic
 
The long-term clinical significance of changes in BMD is not known.
 
At Week 48, BMD declines of ≥5% at the lumbar spine and ≥7% at the total hip were experienced by 4% and 1% of patients, respectively, in both treatment arms1
 
Analysis of these parameters was conducted in a subset of the study population (n=383)1,3
 
BMD was assessed at baseline and Week 48 by dual-energy X-ray absorptiometry (DXA) scans1
 
DESCOVY FOR PrEP had less impact on BMD compared with TRUVADA.1 Increases in BMD observed in DISCOVER patients may be consistent with innate bone development
 
 
Many of the patients in the DISCOVER Trial were under 30, an age at which many people still experience bone growth.3-5
 
Important Safety Information (cont'd)
 
Contraindication
 
DESCOVY FOR PrEP is contraindicated in patients with unknown or positive HIV status
 
 
Warnings and precautions
 
Comprehensive management to reduce risks:
 
Use DESCOVY FOR PrEP to reduce the risk of HIV-1 infection as part of a comprehensive strategy that includes adherence to daily dosing and safer sex practices, including condoms, to reduce the risk of sexually transmitted infections (STIs)
 
HIV-1 risk factors: Behavioral, biological, or epidemiologic HIV-1 risk factors may include, but are not limited to: condomless sex, past or current STIs, self-identified HIV risk, having sexual partners of unknown HIV-1 viremic status, or sexual activity in a high-prevalence area or network
 
Reduce STI risk: Counsel on the use of STI prevention measures (e.g., consistent and correct condom use, knowledge of partner’s HIV-1 viremic status, regular testing for STIs)
 
Reduce potential for drug resistance: Only prescribe DESCOVY FOR PrEP to patients confirmed to be HIV negative immediately prior to initiation, at least every 3 months while taking DESCOVY, and upon an STI diagnosis. HIV-1 resistance substitutions may emerge in patients with undetected HIV-1 infection who are taking only DESCOVY because DESCOVY alone is not a complete regimen for treating HIV-1
 
Some HIV tests may not detect acute HIV infection. Prior to initiating DESCOVY FOR PrEP, ask patients about potential recent exposure events. If recent (<1 month) exposures are reported or suspected, or symptoms of acute HIV infection (e.g., fever, fatigue, myalgia, skin rash) are present, confirm HIV-negative status with a test approved by the FDA for use in the diagnosis of acute HIV infection
 
If HIV-1 infection is suspected or if symptoms of acute infection are present while taking DESCOVY FOR PrEP, convert the DESCOVY FOR PrEP regimen to a complete HIV treatment regimen until HIV-negative status is confirmed by a test approved by the FDA for use in the diagnosis of acute HIV infection
 
Counsel on adherence: Counsel patients to strictly adhere to daily dosing, as efficacy is strongly correlated with adherence. Some patients, such as adolescents, may benefit from more frequent visits and counseling
 
New onset or worsening renal impairment: Cases of acute renal failure and Fanconi syndrome have been reported with the use of tenofovir prodrugs. Do not initiate DESCOVY in patients with estimated creatinine clearance (CrCl) <30 mL/min. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue DESCOVY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Monitor renal function in all patients (see Dosage and Administration section)
 
Lactic acidosis and severe hepatomegaly with steatosis: Fatal cases have been reported with the use of nucleoside analogs, including FTC and TDF. Discontinue use if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations

Important Safety Information (cont'd)
 
Adverse reactions
 
Most common adverse reactions (≥2%) in the DESCOVY FOR PrEP clinical trial were diarrhea, nausea, headache, fatigue, and abdominal pain
 
Drug interactions
 
Prescribing information: Consult the full Prescribing Information for DESCOVY for more information, warnings, and potentially significant drug interactions, including clinical comments
 
Metabolism: Drugs that inhibit P-gp can increase the concentrations of tenofovir alafenamide (TAF), a component of DESCOVY. Drugs that induce P-gp can decrease the concentrations of TAF, which may lead to loss of efficacy
 
Drugs affecting renal function: Coadministration of DESCOVY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of FTC and tenofovir and the risk of adverse reactions
 
 
Dosage and administration
 
Dosage: One tablet taken once daily with or without food
 
HIV screening: Test for HIV-1 infection immediately prior to initiating, at least every 3 months during use, and upon diagnosis of an STI (see Warnings and Precautions section)
 
HBV screening: Test for HBV infection prior to or when initiating DESCOVY
 
Renal impairment and monitoring: Not recommended in patients with creatinine clearance (CrCl) <30 mL/min. Prior to or when initiating DESCOVY, and during use on a clinically appropriate schedule, assess serum creatinine, CrCl, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, assess serum phosphorus
