Merck Announces Positive Top-Line Results from Pivotal Phase 3 Trials Evaluating Investigational, Once-Daily Oral Fixed Dose Combination of Doravirine/Islatravir for the Treatment of People with HIV-1 Infection

Week 48 Data Met Safety and Efficacy Endpoints in Adults with HIV-1 Infection Currently on Antiretroviral Therapy

Merck, known as MSD outside the United States and Canada, moment blazoned positive top- line results from two vital Phase 3 trials of the investigational, formerly-diurnal oral fixed cure combination lozenge of doravirine/ islatravir (DOR/ ISL) in grown-ups with HIV-1 infection who are virologically suppressed on different antiretroviral remedy rules ( ART; ILLUMINATE SWITCH A) or bictegravir/ emtricitabine/ tenofovir (BIC/ FTC/ TAF; ILLUMINATE SWITCH B). At 48 weeks, both trials met their primary efficacity endpoint of chance of actors with HIV-1 RNA situations ≥ 50 clones/ mL, demonstrating that antiviral efficacity was similar between DOR/ ISL and ART ( ILLUMINATE SWITCH A) and between DOR/ ISL and BIC/ FTC/ TAF (ILLUMINATE SWITCH B). The safety and tolerability profile of DOR/ ISL during the trials to date are harmonious with the preliminarily reported Phase 2 studies. Doravirine is approved for the treatment of grown-ups with HIV-1 in combination with other antiretrovirals, as a single agent (PIFELTRO) and a element of a single- tablet authority (DELSTRIGO; DOR/ 3TC/ TDF). Islatravir is Merck’s investigational nucleoside rear transcriptase translocation asset under evaluation for the treatment of people living with HIV-1 infection in combination with other antiretrovirals.
Merck Research Laboratories. “ We’re encouraged by the results from the Phase 3 ILLUMINATE SWITCH A and B trials, in which the DOR/ ISL binary authority efficacity was similar to certain generally used three- medicine rules. We’ll continue to study doravirine/ islatravir in different populations of people living with HIV and look forward to participating data from these trials.”

The ILLUMINATE clinical trial program is assessing DOR/ ISL in a broad patient population, which includes people with HIV-1 who are virologically suppressed on ART, those who are heavily treatment educated and those who are new to HIV treatment. The clinical trial program also includes pediatric actors with HIV-1 importing at least 35 kg who are virologically suppressed and haven’t preliminarily been treated. Merck is committed to enrolling different people in our HIV-1 clinical trials, especially among communities who may be disproportionately impacted by HIV, similar as women and those within the Black and Latinx communities.
PIFELTRO and DELSTRIGO

PIFELTRO (doravirine, 100 mg) is indicated in combination with other antiretroviral (ARV) agents for the treatment of HIV-1 infection in adult cases with no previous ARV treatment history or to replace the current ARV authority in those who are virologically suppressed (HIV-1 RNA lower than 50 clones per mL) on a stable ARV authority with no history of treatment failure and no given negotiations associated with resistance to doravirine.

DELSTRIGO (doravirine, 100 mg/ lamivudine 300 mg/ tenofovir disoproxil fumarate, 300 mg) is indicated as a complete authority for the treatment of HIV-1 infection in adult cases with no previous ARV treatment history or to replace the current ARV authority in those who are virologically suppressed (HIV-1 RNA lower than 50 clones per mL) on a stable ARV authority with no history of treatment failure and no given negotiations associated with resistance to the individual factors of DELSTRIGO. DELSTRIGO contains a boxed warning regardingpost-treatment acute exacerbations of hepatitis B (HBV) infection. See Named Safety Information below.

Named Safety Information about PIFELTRO and DELSTRIGO

Warning Posttreatment Acute Exacerbation of Hepatitis B (HBV)

All cases with HIV-1 should be tested for the presence of HBV before initiating ARV remedy. Severe acute exacerbations of HBV have been reported in cases who are coinfected with HIV-1 and HBV and have discontinued products containing lamivudine or tenofovir disoproxil fumarate (TDF), which are factors of DELSTRIGO. Cases coinfected with HIV-1 and HBV who discontinue DELSTRIGO should be covered with both clinical and laboratory follow-up for at least several months after stoppingDELSTRIGO.However, inauguration ofanti-HBV remedy may be warranted, If applicable.

PIFELTRO and DELSTRIGO are contraindicated whenco-administered with medicines that are strong cytochrome P450 (CYP) 3A enzyme corrupters ( including the anticonvulsants carbamazepine, oxcarbazepine, phenobarbital, and phenytoin; the androgen receptor asset enzalutamide; the antimycobacterials rifampin and rifapentine; the cytotoxic agent mitotane; and the herbal productSt. John’s wort (Hypericum perforatum)), as significant diminishments in doravirine tube attention may do, which may drop the effectiveness of DELSTRIGO and PIFELTRO.

DELSTRIGO is contraindicated in cases with a former acuity response to lamivudine.

Renal impairment, including cases of acute renal failure and Fanconi pattern, have been reported with the use of TDF. DELSTRIGO should be avoided with concurrent or recent use of a nephrotoxic agent (eg, high- cure or multiple NSAIDs). Cases of acute renal failure after inauguration of high- cure or multiple NSAIDs have been reported in cases with threat factors for renal dysfunction who appeared stable on TDF.

Previous to or when initiating DELSTRIGO, and during treatment, assess serum creatinine, estimated creatinine concurrence, urine glucose, and urine protein in all cases. In cases with habitual order complaint, also assess serum phosphorus. Discontinue DELSTRIGO in cases who develop clinically significant diminishments in renal function or substantiation of Fanconi pattern. Discontinue DELSTRIGO if estimated creatinine concurrence declines below 50 mL/ min.
