tsignificantly prolonged. A secondary effect would be the drug’s inhibitionof sodium channels.22Vernakalant possesses a quick onset of action, Docetaxel and its halflifeis two hours. It can be 25% to 50% protein-bound. This drug ismetabolized by CYP2D6 to its significant active metabolite,RSD1385, which is then conjugated to its inactive type. Vernakalanthas not been shown to induce or inhibit the CYP2D6isoenzyme.23The dose becoming studied is 3 mg/kg in an IV formulation, offered over a period of 10 minutes. An additionaldose of 2 mg/kg, offered over 10 minutes, may be prescribed15 minutes later if conversion to NSR has not occurred. Doseadjustments are not necessary in relation to the patient’s age,sex, or degree of renal impairment.It has not been determined whether or not adjustments must bemade for patients with hepatic impairment.
Formal studiesinvolving drug interactions of vernakalant Docetaxel have not been conducted.Due to the fact vernakalant is not highly protein-bound, it isthought that it doesn't interact with other highly proteinbounddrugs, Gemcitabine such as amiodarone, warfarin, phenytoin, diltiazem, and verapamil.24Vernakalant Versus PlaceboVernakalant has been evaluated in a number of trials as a novelagent for conversion to NSR. Four phase 3 studies, conductedby Atrial Arrhythmia Conversion Trialinvestigators,evaluated the drug’s safety and efficacy. The very first three trialswere similar in design. The exclusion criteria for these trialsincludedpregnant or nursing womenand patients with sick sinus syndrome, a QRS greater than0.
14 seconds devoid of a pacemaker, a ventricular rate of lessthan 50 beats per minute, an uncorrected QT interval greaterthan 440 msec, NYHA Class IV heart failure, a reversible causeof AF, and end-stage disease.The main outcome NSCLC was utilized in all of the trials too andwas defined as the number of patients experiencing NSR forat least 1 minute within 90 minutes of starting vernakalant.The dose utilized was 3 mg/kg IV, followed by 2 mg/kg if theparticipant did not knowledge conversion to NSR. The mostcommon AEs in these trials had been AF, nausea, dysgeusia, sneezing,and paraesthesia.24–26In ACT I, the very first of these studies,25 patients had been stratifiedbased on the duration of AF. Seventy-five patientswithAF lasting from three hours to seven daysachieved the main endpoint, compared with 4% ofthose in the placebo group.
In ACT II, a study of postoperative AF patients, 45% of vernakalantpatients knowledgeable conversion to NSR in the first90 minutes, with a median time to conversion of 12 minutes,compared with 15% of placebo patients.26In ACT III, 51% of patients receiving vernakalantexperiencedconversion to NSR in eight minutes on average,compared with 4% of placebo Gemcitabine patients.27ACT IV,28 an open-label study, was conducted to gainadditional insight into the safety of making use of 3 mg/kg plus 2 mg/kg from the drug if necessary. The main efficacy measure wasthe proportion of patients with recent-onset AF who experiencedconversion to NSR for a minimum of 1 minute within 90 min-utes right after the start off from the initial infusion. In this trial, 51% ofthose receiving vernakalantexperienced conversionto NSR in 14 minutes on average.
There had been no deaths withinthe 1st 24 hours of vernakalant administration; Docetaxel 1 patientwith breast cancer died throughout the 30-day follow-up periodfrom an upper GI hemorrhage. Essentially the most common significant AEswere bradycardiaand hypotension. The mostcommon treatment-emergent AEs had been dysgeusia,sneezing, paresthesia, and cough.Vernakalant Versus AmiodaroneIn the Active-Controlled, Multicenter Study of VernakalantInjection versus Amiodarone in Subjects with Recent OnsetAtrial Fibrillation, 116 subjects with AF lasting forthree to 48 hours had been randomly assigned to receive eithervernakalant or amiodarone. Amiodarone was offered as a loadingdose of 5 mg/kg, followed by a one-hour maintenanceinfusion of 50 mg.The main endpoint in AVRO was the same utilized in ACTand was reached by 51.7% from the vernakalant patients and by5.2% from the amiodarone group.
Side effects weresimilar to the results found in other studies too.29Following the submission of an NDA to the FDA in December2007, vernakalant was suggested for approval Gemcitabine by theFDA Cardiovascular and Renal Drugs Advisory Committee forconversion of recent-onset AF. In August 2008, the FDArequested added safety data.28,30 In October 2010, ACT V,a phase 3b randomized clinical trial that evaluated the safetyand efficacy of vernakalant, was suspended right after a subject receivingthe study drug developed cardiogenic shock. ACT Vevaluated patients with recent-onset, symptomatic AFwith no history of heart failure. Specificinformation about the patient who developed cardiogenicshock is unknown.Due to this event, the European Medicines Agencyupdated the contraindications of vernakalant to warn againstthe use of Class I and III antiarrhythmic medications withinfour hours of administration of vernakalant.31 Presently, theFDA is continuing to overview all available data. Vernakalantwas approved for use in Septem
