KENILWORTH, N.J.–(BUSINESS WIRE)–
Merck & Co., Inc. (MRK), accepted as MSD alfresco the United States and Canada, today arise that the New England Account of Anesthetic has arise online the capital after-effects from the cardinal Phase 3 analytic abstraction of PREVYMIS™ (letermovir), the company’s new anesthetic for prophylaxis (prevention) of cytomegalovirus (CMV) infection and ache in developed CMV-seropositive recipients [R ] of an allogeneic hematopoietic axis corpuscle displace (HSCT). The cardboard will additionally arise in a accessible book affair of the journal.
CMV-seropositive patients who abide allogeneic hematopoietic-cell transplantation are at aerial accident for CMV reactivation. CMV infection is a accepted clinically cogent aggravation in these patients and aboriginal CMV reactivation afterwards displace is associated with added mortality. PREVYMIS is a first-in-class antiviral biologic that inhibits CMV replication.
“This abstraction culminates added than a decade of efforts to analyze new, awful able antiviral medicines for patients that can be assigned prophylactically afterwards hematopoietic-cell transplantation,” said Dr. Francisco M. Marty, accessory assistant of anesthetic at Harvard Medical School and accessory physician in displace and oncology communicable diseases at Dana-Farber Blight Institute and Brigham and Women’s Hospital.
In the study, decidedly beneath patients in the PREVYMIS arm (37.5%, n=122/325) compared to the placebo arm (60.6%, n=103/170) developed clinically cogent CMV infection, discontinued analysis or had missing abstracts through Week 24 post-transplant (p<0.001), the primary adeptness endpoint. The analysis aftereffect for PREVYMIS in preventing clinically cogent CMV infection was constant beyond pre-specified high- and low-risk strata for CMV reactivation both at Week 14 (end of treatment) and at Week 24 post-transplant. All-cause bloodshed in patients accepting PREVYMIS was lower compared to placebo at Week 24 post-transplant and at Week 48 post-transplant.
PREVYMIS is contraindicated in patients accepting pimozide or ergot alkaloids. Added pimozide concentrations may beforehand to QT assiduity and torsades de pointes. Added ergot alkaloids concentrations may beforehand to ergotism. PREVYMIS is contraindicated with pitavastatin and simvastatin back co-administered with cyclosporine. Decidedly added pitavastatin or simvastatin concentrations may beforehand to myopathy or rhabdomyolysis.
“Merck has been alive to accompany PREVYMIS advanced to abode the cogent unmet medical charge for hematopoietic axis corpuscle displace recipients – a accessible accommodating citizenry at accident from CMV infection and disease,” said Dr. Nicholas Kartsonis, carnality president, communicable ache analytic research, Merck Analysis Laboratories. “Based on the after-effects of this study, in accession to the contempo U.S. approval of PREVYMIS, Merck has authoritative applications awaiting in added markets, including in the European Union and Japan.”
PREVYMIS will be accessible for acclimation in the U.S. in aboriginal December.
This double-blind abstraction randomized developed CMV-seropositive allogeneic hematopoietic-cell displace recipients to accept PREVYMIS or placebo orally or intravenously through Week 14 post-transplant. PREVYMIS was dosed at 480 mg/day (or 240 mg/day back co-administered with cyclosporine). Patients who developed clinically-significant CMV infection, authentic as CMV ache or CMV viremia acute preemptive treatment, discontinued abstraction biologic and accustomed anti-CMV treatment. All patients in the abstraction were followed through Week 48 post-transplant.
Key prespecified accessory endpoints of the abstraction were the admeasurement of patients with clinically-significant CMV infection through Week 14 and the time to clinically-significant CMV infection in the primary adeptness population. All advised patients were included in the assurance analyses. Prespecified basic endpoints of the abstraction included accumulative all-cause mortality, time to engraftment, and the accident of graft-versus-host ache or non-CMV infections.
Additional Selected Assurance Advice about PREVYMIS (letermovir)
The accessory use of PREVYMIS and assertive drugs may aftereffect in potentially cogent biologic interactions, some of which may beforehand to adverse reactions (PREVYMIS or accessory drugs) or bargain ameliorative aftereffect of PREVYMIS or the accessory drug. Consider the abeyant for biologic interactions above-mentioned to and during PREVYMIS therapy; analysis accessory medications during PREVYMIS therapy; and adviser for adverse reactions associated with PREVYMIS and accessory medications.
The cardiac adverse accident amount (regardless of investigator-assessed causality) was college in patients accepting PREVYMIS than placebo (13% vs. 6%). The best accepted cardiac adverse contest were tachycardia (reported in 4% PREVYMIS patients and 2% placebo patients) and atrial fibrillation (reported in 3% PREVYMIS patients and 1% placebo patients). These adverse contest were appear as balmy or abstinent in severity.
The amount of adverse contest occurring in at atomic 10% of PREVYMIS-treated HSCT recipients and at a abundance at atomic 2% greater than placebo were abhorrence (27% vs. 23%), diarrhea (26% vs. 24%), airsickness (19% vs. 14%), borderline edema (14% vs. 9%), ahem (14% vs. 10%), cephalalgia (14% vs. 9%), fatigue (13% vs. 11%), and belly affliction (12% vs. 9%).
The best frequently appear adverse accident that led to abstraction biologic cessation was abhorrence (occurring in 2% of PREVYMIS patients and 1% of placebo patients). Hypersensitivity reaction, with associated abstinent dyspnea, occurred in one accommodating afterward the aboriginal beverage of IV PREVYMIS afterwards switching from articulate PREVYMIS, arch to analysis discontinuation.
Co-administration of PREVYMIS (letermovir) with drugs that are inhibitors of amoebic anion-transporting polypeptide 1B1/3 (OATP1B1/3) transporters may aftereffect in increases in letermovir claret concentrations.
Co-administration of PREVYMIS with midazolam after-effects in added midazolam claret concentration. Co-administration of PREVYMIS with drugs that are CYP3A substrates may aftereffect in clinically accordant increases in the claret concentrations of co-administered CYP3A substrates.
Co-administration of PREVYMIS with drugs that are substrates of OATP1B1/3 transporters may aftereffect in a clinically accordant admission in claret concentrations of co-administered OATP1B1/3 substrates.
The consequence of CYP3A- and OATP1B1/3-mediated biologic interactions on co-administered drugs may be altered back PREVYMIS is co-administered with cyclosporine. See the prescribing advice for cyclosporine for advice on biologic interactions with cyclosporine.
If dosage adjustments of accessory medications are fabricated due to analysis with PREVYMIS, doses should be readjusted afterwards PREVYMIS analysis is completed.
Established or potentially clinically cogent biologic interactions may action with co-administration of PREVYMIS and drug/drug classes, including, but not bound to, the following:
The assurance and adeptness of PREVYMIS (letermovir) in patients beneath 18 years of age accept not been established.
For patients with creatinine approval (CLcr) greater than 10 mL/min (by Cockcroft-Gault equation), no dosage acclimation of PREVYMIS is appropriate based on renal impairment. The assurance of PREVYMIS in patients with end-stage renal ache (CLcr beneath than 10 mL/min), including patients on dialysis, is unknown.
No dosage acclimation of PREVYMIS is appropriate based on balmy (Child-Pugh Chic A) to abstinent (Child-Pugh Chic B) hepatic impairment. PREVYMIS is not recommended for patients with astringent (Child-Pugh Chic C) hepatic impairment.
