Drug Details [pdf]

  • 1 INDICATIONS AND USAGE


    Lofexidine tablets are indicated for mitigation of opioid withdrawal symptoms to facilitate abrupt opioid discontinuation in adults.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Dosing Information


    The usual lofexidine tablets starting dosage is three 0.18 mg tablets taken orally 4 times daily during the period of peak withdrawal symptoms (generally the first 5 to 7 days following last use of opioid) with dosing guided by symptoms and side effects. There should be 5 to 6 hours between each dose. The total daily dosage of lofexidine tablets should not exceed 2.88 mg (16 tablets) and no single dose should exceed 0.72 mg (4 tablets). 

    Lofexidine tablets treatment may be continued for up to 14 days with dosing guided by symptoms. 

    Discontinue lofexidine tablets with a gradual dose reduction over a 2- to 4-day period to mitigate lofexidine tablets withdrawal symptoms (e.g., reducing by 1 tablet per dose every 1 to 2 days). [see Warnings & Precautions (5.5)].The lofexidine tablets dose should be reduced, held, or discontinued for individuals who demonstrate a greater sensitivity to lofexidine tablets side effects [see Adverse Reactions (6.1), Warnings and Precautions (5.1)]. Lower doses may be appropriate as opioid withdrawal symptoms wane. 

    Lofexidine tablets can be administered in the presence or absence of food.

    2.2 Dosage Recommendations for Patients with Hepatic Impairment


    Recommended dosage adjustments based on the degree of hepatic impairment are shown in Table 1. [see Use in Specific Populations (8.5), Clinical Pharmacology (12.3)].

  • 3 DOSAGE FORMS AND STRENGTHS


    Lofexidine tablet is available as round, concave-shaped, peach-colored, film-coated tablets, debossed with “C” on one side and “71” on other side. Each tablet contains 0.18 mg lofexidine (equivalent to 0.2 mg of lofexidine hydrochloride).

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Risk of Hypotension, Bradycardia and Syncope


    Lofexidine tablet can cause a decrease in blood pressure, a decrease in pulse, and syncope [see Adverse Reactions (6.1), Clinical Pharmacology (12.2)]. Monitor vital signs before dosing. Monitor symptoms related to bradycardia and orthostasis.

    Patients being given lofexidine tablet  in an outpatient setting should be capable of and instructed on self-monitoring for hypotension, orthostasis, bradycardia, and associated symptoms. If clinically significant or symptomatic hypotension and/or bradycardia occur, the next dose of lofexidine  tablet should be reduced in amount, delayed, or skipped.

    Inform patients that lofexidine tablet may cause hypotension and that patients moving from a supine to an upright position may be at increased risk for hypotension and orthostatic effects. Instruct patients to stay hydrated, on how to recognize symptoms of low blood pressure, and how to reduce the risk of serious consequences should hypotension occur (e.g., sit or lie down, carefully rise from a sitting or lying position). Instruct outpatients to withhold lofexidine tablet doses when experiencing symptoms of hypotension or bradycardia and to contact their health care provider for guidance on how to adjust dosing.

    Avoid use lofexidine tablets in patients with severe coronary insufficiency, recent myocardial infarction, cerebrovascular disease, chronic renal failure, and in patients with marked bradycardia.


    Avoid use lofexidine tablets in combination with medications that decrease pulse or blood pressure to avoid the risk of excessive bradycardia and hypotension.

    5.2 Risk of QT Prolongation


    Lofexidine tablet prolongs the QT interval.
    Avoid using lofexidine tablet  in patients with congenital long QT syndrome. 
    Monitor ECG in patients with congestive heart failure, bradyarrhythmias, hepatic impairment, renal impairment, or patients taking other medicinal products that lead to QT prolongation (e.g. methadone). In patients with electrolyte abnormalities (e.g., hypokalemia or hypomagnesemia), correct these abnormalities first, and monitor ECG upon initiation of lofexidine tablet [see Dosing and Administration (2.1) Adverse Reactions (6.1), Special Populations (8.6)(8.7), Clinical Pharmacology (12.2)].


    5.3 Increased Risk of Central Nervous System Depression with Concomitant use of CNS Depressant Drugs


    Lofexidine tablet potentiates the CNS depressive effects of benzodiazepines, and can also be expected to potentiate the CNS depressive effects of alcohol, barbiturates, and other sedating drugs. Advise patients to inform their healthcare provider of other medications they are taking, including alcohol.
    Advise patients using lofexidine tablet in an outpatient setting that, until they learn how they respond to lofexidine tablet, they should be careful or avoid doing activities such as driving or operating heavy machinery.


    5.4 Increased Risk of Opioid Overdose after Opioid Discontinuation


    Lofexidine tablet is not a treatment for opioid use disorder. Patients who complete opioid discontinuation are likely to have a reduced tolerance to opioids and are at increased risk of fatal overdose should they resume opioid use. Use lofexidine tablet in patients with opioid use disorder only in conjunction with a comprehensive management program for the treatment of opioid use disorder and inform patients and caregivers of this increased risk of overdose.

    5.5 Risk of Discontinuation Symptoms


    Stopping lofexidine  tablet abruptly can cause a marked rise in blood pressure. Symptoms including diarrhea, insomnia, anxiety, chills, hyperhidrosis, and extremity pain have also been observed with lofexidine  tablet discontinuation. Instruct patients not to discontinue therapy without consulting their healthcare provider. When discontinuing therapy with lofexidine tablet, gradually reduce the dose [see Dosing and Administration (2.1)].
    Symptoms related to discontinuation can be managed by administration of the previous lofexidine  tablet dose and subsequent taper.


  • 6 ADVERSE REACTIONS

    The following serious adverse reactions are described elsewhere in labeling: 
     Hypotension, Bradycardia, and Syncope [see Warnings and Precautions (5.1)] 
     QT Prolongation [see Warnings and Precautions (5.2)] 
     Central Nervous System Depression [see Warnings and Precautions (5.3)] 
     Opioid Overdose [see Warnings and Precautions (5.4)]
     Discontinuation Symptoms [see Warnings and Precautions (5.5)]



    6.1 Clinical Trials Experience


    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to adverse reaction rates observed for another drug and may not reflect the rates observed in practice.
    The safety of lofexidine was supported by 3 randomized, double-blind, placebo-controlled clinical trials, an open-label study, and clinical pharmacology studies with concomitant administration of either methadone, buprenorphine, or naltrexone.
    The 3 randomized, double-blind, placebo-controlled clinical trials enrolled 935 subjects dependent on short-acting opioids undergoing abrupt opioid withdrawal. Patients were monitored before each dose in an inpatient setting.
    Table 3 presents the incidence, rounded to the nearest percent, of adverse events that occurred in at least 10% of subjects treated with lofexidine and for which the incidence in patients treated with lofexidine was greater than the incidence in subjects treated with placebo in a study that tested two doses of lofexidine, 2.16 mg per day and 2.88 mg per day, and placebo. The overall safety profile in the combined dataset was similar.
    Orthostatic hypotension, bradycardia, hypotension, dizziness, somnolence, sedation, and dry mouth were notably more common in subjects treated with lofexidine tablet than subjects treated with placebo.

    * Assigned dose; mean average daily dose received was 79% of assigned dose due to dose-holds for out-of-range vital signs.

    Other notable adverse reactions associated with the use of lofexidine tablet but reported in <10% of patients in the lofexidine tablet group included: 
    Syncope: 0.9%, 1.4% and 0% for lofexidine tablet 2.16 mg/day and 2.88 mg/day and placebo,respectively 
    Tinnitus: 0.9%, 3.2% and 0% for lofexidine tablet 2.16 mg/day and 2.88 mg/day and placebo,respectively


    Blood pressure changes and adverse reactions after lofexidine tablet  cessation
    Elevations in blood pressure above normal values (≥ 140 mmHg systolic) and above a subject’s pre-treatment baseline are associated with discontinuing lofexidine tablet, and peaked on the second day after discontinuation, as shown in Table 4. Blood pressure values were evaluated for 3 days following the last dose of a 5-day course of lofexidine tablet  2.88mg/day.

    Blood pressure elevations of a similar magnitude and incidence were observed in a small number of patients (N=10) that had a one-day, 50% dose reduction prior to discontinuation.
    After stopping treatment, subjects that were taking  lofexidine tablet  also had a higher incidence of diarrhea, insomnia anxiety, chills, hyperhidrosis, and extremity pain compared to subjects that were taking placebo.

    Sex-specific adverse event findings
    Four out of 101 females (4%) had a serious cardiovascular adverse events compared to 3 out of 289 (1%) of males assigned to receive lofexidine tablet 2.88 mg per day.
    Discontinuations and dose holds due to bradycardia and orthostatic hypotension, which are the most common adverse reactions associated with lofexidine tablet, occurred with a greater incidence in females assigned to receive the highest studied dose of lofexidine tablet, 2.88 mg per day as shown in Table 5.

    6.2 Postmarketing Experience


    Lofexidine is marketed in other countries for relief of opioid withdrawal symptoms. The following events have been identified during postmarketing use of lofexidine. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
    Since lofexidine’s initial market introduction in 1992, the most frequently reported postmarketing adverse event with lofexidine has been hypotension [see Warnings and Precautions (5.1)]. There has been one report of QT prolongation, bradycardia, torsades de pointes, and cardiac arrest with successful resuscitation in a patient that received lofexidine and three reports of clinically significant QT prolongation in subjects concurrently receiving methadone with lofexidine.


  • 7 DRUG INTERACTIONS

    7.1 Methadone


    Lofexidine tablet and methadone both prolong the QT interval. ECG monitoring is recommended in patients receiving methadone and lofexidine tablet [seeWarnings and Precautions (5.2), Clinical Pharmacology (12.3)].

    7.2 Oral Naltrexone


    Coadministration of lofexidine tablet and oral naltrexone resulted in statistically significant differences in the steady-state pharmacokinetics of naltrexone. It is possible that oral naltrexone efficacy may be reduced if used concomitantly within 2 hours of lofexidine tablet.This interaction is not expected if naltrexone is administered by non-oral routes [see Clinical Pharmacology (12.3)].

    7.3 CNS Depressant Drugs


    Lofexidine tablet potentiates the CNS depressant effects of benzodiazepines and may potentiate the CNS depressant effects of alcohol, barbiturates, and other sedating drugs. Advise patients to inform their healthcare provider of other medications they are taking, including alcohol [see Warnings and Precautions (5.3)].

    7.4 CYP2D6 Inhibitor - Paroxetine


    Coadministration of lofexidine tablet and paroxetine resulted in 28% increase in the extent of absorption of lofexidine tablet. Monitor for orthostatic hypotension and bradycardia when an inhibitor of CYP2D6 is used concomitantly with lofexidine tablet [see Clinical Pharmacology (12.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary 
    The safety of lofexidine tablet in pregnant women has not been established. In animal reproduction studies, oral administration of lofexidine during organogenesis to pregnant rats and rabbits caused a reduction in fetal weights, increases in fetal resorptions, and litter loss at exposures below that in humans. When oral lofexidine was administered from the beginning of organogenesis through lactation, increased stillbirths and litter loss were noted along with decreased viability and lactation indicies. The offspring exhibited delays in sexual maturation, auditory startle, and surface righting. These effects occurred at exposures below that in humans [see Animal Data].
    The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies carry some risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects in the U.S. general population is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.

    Data 
    Animal Data 
    Increased incidence of resorptions, decreased number of implantations, and a concomitant reduction in the number of fetuses were observed when pregnant rabbits were orally administered lofexidine hydrochloride during organogenesis (from gestation day [GD] 7 to 19) at a daily dose of 5.0 mg/kg/day (approximately 0.08 times the maximum recommended human dose [MRHD] of 2.88 mg lofexidine base on an AUC basis). Maternal toxicity evidenced by increased mortality was noted at the highest tested dose of 15 mg/kg/day (approximately 0.4 times the MRHD on an AUC basis).
    Decreased implantations per dam and decreased mean fetal weights were noted in a study in which pregnant rats were treated with oral lofexidine hydrochloride during organogenesis (from GD 7 to 16) at a daily dose of 3.0 mg/kg/day (approximately 0.9 times the MRHD on an AUC basis). This dose was associated with maternal toxicity (decreased body weight gain and mortality). No malformations or evidence of developmental toxicity were evident at 1.0 mg/kg/day (approximately 0.2 times the MRHD on an AUC basis).

    A dose-dependent increase in pup mortality was noted in all doses of lofexidine hydrochloride administered orally to pregnant rats from GD 6 through lactation at an exposure less than the human exposure based on AUC comparisons. Doses higher than 1.0 mg/kg/day (approximately 0.2 times the MRHD on an AUC basis) resulted in incidences of total litter loss and maternal toxicity (piloerection and decreased body weight gain). The highest dose tested of 2.0 mg/kg/day (approximately 0.6 times the MRHD on an AUC basis), increased stillbirths as well as decreased viability and lactation indices were reported. Surviving offspring exhibited lower body weights, developmental delays, and increased delays in auditory startle at doses of 1.0 mg/kg/day or higher. Sexual maturation was delayed in male offspring (preputial separation) at 2.0 mg/kg/day and in female offspring (vaginal opening) at 1.0 mg/kg/day or higher.


    8.2 Lactation

    Risk Summary


    There is no information regarding the presence of lofexidine tablet or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Caution should be exercised when lofexidine tablet is administered to a nursing woman.
    The developmental and health benefits should be considered along with the mother’s clinical need for lofexidine tablet and any other potential adverse effects on breast-fed children from lofexidine tablet or from the underlying maternal condition.

    8.3 Females and Males of Reproductive Potential


    In animal studies that included some fertility endpoints, lofexidine decreased breeding rate and increased resorptions at exposures below human exposures. The impact of lofexidine on male fertility has not be adequately characterized in animal studies [see Impariment of Fertility (13.1)].

    8.4 Pediatric Use


    The safety and effectiveness of lofexidine tablet have not been established in pediatric patients.

    8.5 Geriatric Use


    No studies have been performed to characterize the pharmacokinetics of lofexidine tablet or establish its safety and effectiveness in geriatric patients. Caution should be exercised when it is administered to patients over 65 years of age. Dosing adjustments similar to those recommended in patients with renal impairment should be considered [see Dosage and Administration (2.3), Use in Specific Populations (8.6)].

    8.6 Hepatic Impairment


    Hepatic impairment slows the elimination of lofexidine tablet but exhibits less effect on the peak plasma concentration than on AUC values following a single dose. Dosage adjustments are recommended based on the degree of hepatic impairment. [see Dosage and Administration (2.2), Clinical Pharmacology (12.2)]. 
     
    Clinically relevant QT prolongation may occur in subjects with hepatic impairment [see Warnings and Precautions (5.2), Clinical Pharmacology (12.2)].


    8.7 Renal Impairment


    Renal impairment slows the elimination of lofexidine tablet but exhibits less effect on the peak plasma concentration than on AUC values following a single dose. Dosage adjustments are recommended based on the degree of renal impairment [see Dosage and Administration (2.3), Clinical Pharmacology (12.3)].

    Only a negligible fraction of the lofexidine tablet dose is removed during a typical dialysis session, so no additional dose needs to be administered after a dialysis session; lofexidine tablet may be administered without regard to the timing of dialysis [see Dosage and Administration (2.3), Clinical Pharmacology (12.3)].
    Clinically relevant QT prolongation may occur in subjects with renal impairment [see Warnings and Precautions (5.2), Clinical Pharmacology (12.2)].


    8.8 CYP2D6 Poor Metabolizers


    Although the pharmacokinetics of lofexidine tablet have not been systematically evaluated in patients who do not express the drug metabolizing enzyme CYP2D6, it is likely that the exposure to lofexidine tablet would be increased similarly to taking strong CYP2D6 inhibitors (approximately 28%). Monitor adverse events such as orthostatic hypotension and bradycardia in known CYP2D6 poor metabolizers. Approximately 8% of Caucasians and 3–8% of Black/African Americans cannot metabolize CYP2D6 substrates and are classified as poor metabolizers (PM) [seeClinical Pharmacology (12.3)].

  • 10 OVERDOSAGE


    Overdose with lofexidine tablet may manifest as hypotension, bradycardia, and sedation. In the event of acute overdose, perform gastric lavage where appropriate. Dialysis will not remove a substantial portion of the drug. Initiate general symptomatic and supportive measures in cases of overdosage.

  • 11 DESCRIPTION


    Lofexidine tablets contain lofexidine, a central alpha-2 adrenergic agonist, as the hydrochloride salt. Lofexidine hydrochloride is chemically designated as 2-[1-(2,6-dichlorophenoxy)ethyl]-4,5 dihydro-1H- imidazole monohydrochloride with a molecular formula of C11H12Cl2N2OHCl. Its molecular weight is 295.6 g/mole and its structural formula is:


     

    lofexidine-structure


    Lofexidine hydrochloride is a white to off-white crystalline powder freely soluble in water, methanol, and ethanol. It is slightly soluble in chloroform and practically insoluble in n-hexane and benzene.


    Lofexidine tablet is available as round, concave-shaped, peach-colored, film-coated tablets, debossed with “C” on one side and “71” on other side for oral administration. Each tablet contains 0.18 lofexidine, equivalent to 0.2 mg of lofexidine hydrochloride and the following inactive ingredients: 87 mg lactose monohydrate, 12.3 mg citric acid monohydrate, 5.7 mg microcrystalline cellulose, 1.1 mg povidone K-30, 0.70 mg sodium lauryl sulphate, 5.0 mg sodium starch glycolate, 2.0 mg calcium stearate and Opadry AMB II orange 88A530003 (contains polyvinyl alcohol, talc, titanium dioxide, Glyceryl mono and dicaprylocaprate, sodium lauryl sulfate, FD&C yellow #6/sunset yellow FCF aluminum lake and FD&C blue #2/indigo carmine aluminium lake).


  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action


     Lofexidine is a central alpha-2 adrenergic agonist that binds to receptors on adrenergic neurons. This reduces the release of norepinephrine and decreases sympathetic tone.

    12.2 Pharmacodynamics


    Cardiac Electrophysiology
    Single lofexidine doses of 1.44 to 1.8 mg produced maximum mean change from baseline in QTcF (ΔQTcF) of 14.4 msec (upper two-sided 90% CI: 22.3 msec) and 13.6 msec (17.4 msec) for 1.44 and 1.8 mg respectively in healthy normal volunteers.
    In a Phase 3 placebo-controlled, dose-response study in opioid-dependent subjects, lofexidine tablet was associated with a maximum mean prolongation of the QTcF interval 7.3 (8.8)  and 9.3 (10.9) msec at doses of 2.16 and 2.88 mg/day, respectively.


    Patients with hepatic impairment 
    Administration of lofexidine to subjects with hepatic impairment was associated with prolongation of the QTc interval, which was more pronounced in subjects with severe hepatic impairment [seeUse in Specific Populations (8.6)].

     

    Patients with renal impairment 
    Administration of lofexidine tablet to subjects with renal impairment was associated with prolongation of the QTc interval, which was more pronounced in subjects with severe renal impairment [see Use in Specific Populations (8.7)]

     

    Lofexidine coadministered with methadone 
    Lofexidine tablet (2.88 mg/day) coadministered with methadone in 18 methadone-maintained patients (80-120 mg/day) resulted in a maximum mean increase from methadone-alone baseline in QTcF of 9.1 (14.2) msec.


    Lofexidine tablet coadministered with buprenorphine
    Lofexidine tablet (2.88 mg/day) coadministered with buprenorphine in 21 buprenorphine-maintained patients (16-24 mg/day) resulted in a maximum mean QTcF increase in QTcF of 15 (5.6) msec compared to a buprenorphine-alone baseline.


    In Vitro Binding

    Lofexidine tablet exhibits in vitro binding affinity and functional agonist activity with alpha-2A and alpha-2C adrenoreceptors at concentrations within clinical exposure plasma levels (Ki values of approximately 7.2 nM and 12 nM, and EC50 values of 4.9 nM and 0.9 nM, respectively).


    12.3 Pharmacokinetics


    Absorption
    Lofexidine tablet is well absorbed and achieves peak plasma concentration 3 to 5 hours after administration of a single dose.



    Lofexidine tablet shows approximately dose-proportional pharmacokinetics. Administration of lofexidine tablet with food does not alter its pharmacokinetics. 
    The absolute bioavailability of a single oral lofexidine tablet dose ( 0.36 mg in solution) compared with an intravenous infusion (0.2 mg infused for 200 minutes) was 72%. Mean lofexidine tablet Cmax after the oral dose and intravenous infusion was 0.82 ng/mL (at median Tmax of 3 hours) and 0.64 ng/mL (at median Tmax of 4 hours), respectively. Mean estimates of overall systemic exposure (AUCinf) were 14.9 ngh/mL and 12.0 ngh/mL, respectively.


    Distribution

    Mean lofexidine tablet apparent volume of distribution and volume of distribution values following the administration of an oral dose and an intravenous dose were 480.0 L and 297.9 L, respectively, which are appreciably greater than total body volume, suggesting extensive lofexidine tablet distribution into body tissue.

    Lofexidine tablet protein binding is approximately 55%.

    Lofexidine tablet is not preferentially taken up by blood cells. In a study comparing lofexidine tablet concentrations in plasma and whole blood at the time of peak lofexidine tablet concentrations in human volunteers, it was determined that red blood cells contain approximately 27% the lofexidine tablet concentration of the plasma.


    Elimination
    Metabolism
    From absolute bioavailability results, approximately 30% of the administered lofexidine tablet dose is converted to inactive metabolites during the first pass effect associated with drug absorption from the gut.

    Lofexidine tablet and its major metabolites did not induce or inhibit any CYP450 isoforms, with the exception of a slight inhibition of CYP2D6 by lofexidine tablet, with an IC50 of 4551 nM (approximately 225 times the steady-state Cmax for lofexidine tablet with 0.72 mg 4 times daily dosing). Any lofexidine tablet interaction with CYP2D6 substrates is not expected to be clinically significant.

    Lofexidine tablet is metabolized when incubated in vitro with human liver microsomes, the major contributor to the hepatic metabolism of lofexidine tablet is CYP2D6, with CYP1A2 and CYP2C19 also capable of metabolizing lofexidine tablet.


    Excretion 

    The elimination half-life is approximately 12 hours and mean clearance is 17.6 L/h following an IV infusion. 

    Lofexidine tablet has a terminal half-life of approximately 11 to 13 hours following the first dose. At steady-state, the terminal half-life is approximately 17 to 22 hours. Accumulation occurs up to 4 days with repeat dosing, following the recommended dosing regimen. 

    A mass balance study of lofexidine tablet showed nearly complete recovery of radiolabel in urine (93.5%) over 144 hours postdose, with an additional 0.92% recovered in the feces over 216 hours postdose. Thus, it appears that all, or nearly all, of the dose was absorbed, and that the primary route of elimination of the parent drug and its metabolites is via the kidney. Renal elimination of unchanged drug accounts for approximately 15% to 20% of the administered dose.


    Specific Populations
    Hepatic Impairment
    Hepatic impairment slows the elimination of lofexidine tablet but exhibits less effect on the peak plasma concentration following a single dose. In a study comparing the pharmacokinetics of lofexidine tablet (0.36 mg) in mild, moderate, and severe hepatically impaired subjects to subjects with normal hepatic function (6 subjects in each hepatic function group), mean Cmax values were similar for subjects with normal, mild, and moderate hepatic impairment as shown in Table 6.

    Renal Impairment 
    Renal impairment slows the elimination of lofexidine tablet but exhibits less effect on the peak plasma concentration following a single dose. In a study comparing the pharmacokinetics of lofexidine tablet (0.36 mg) in 8 end-stage renal disease subjects on 3 times weekly hemodialysis to 8 subjects with normal renal function matched for sex, age, and body mass index, mean Cmax values were similar for end-stage renal disease and normal renal function subjects, indicating no change in maximum lofexidine tablet exposure with renal impairment as shown in Table 7.



    The impact of dialysis on the overall PK of lofexidine tablet during a typical 4-hour dialysis was minimal; the drop in lofexidine tablet plasma concentrations produced during the dialysis session was transient, with a rebound to nearly predialysis concentrations after re-equilibration within a few hours following completion of the dialysis cycle [see Dosage and Administration (2.3), Use in Specific Populations (8.6)].

     


    In a study comparing the pharmacokinetics of lofexidine tablet (0.36 mg) in 6 subjects each with normal renal function, mild renal impairment, and moderate renal impairment as well as 5 subjects with severe renal impairment but not requiring dialysis, there were similar increases in mean Cmax values in subjects with mild and moderate renal impairment in comparison to subjects with normal renal function with additional increase in mean Cmax values in subjects with severe renal impairment. Mean AUClast, AUC∞, and t1/2 increased with severity of renal impairment as shown in Table 7.

    Drug Interaction Studies
    Lofexidine tablet coadministered with methadone


    In a double-blind placebo-controlled study of 23 patients maintained on a methadone dose of 80-120 mg/day and concomitantly administered lofexidine tablet up to 2.88 mg/day, lofexidine tablet did not alter the pharmacokinetics of methadone. Lofexidine tablet concentrations may be slightly increased when coadministered with methadone; however, the increase at concentrations expected with recommended dosing is not clinically meaningful[see Drug Interactions (7.1)].

    Lofexidine tablet coadministered with buprenorphine
    In a double-blind placebo-controlled study of 30 subjects maintained on buprenorphine (16-24 mg/day) concomitantly administered lofexidine tablet up to 2.88 mg/day, no pharmacokinetic or pharmacodynamic interactions between lofexidine tablet and buprenorphine were seen.


    Lofexidine tablet coadministered with oral naltrexone
    In an open-label, single-arm study of 24 healthy subjects, oral naltrexone (50 mg/day) did not significantly alter the single-dose pharmacokinetics of lofexidine tablet (0.36 mg). The alteration in steady-state pharmacokinetics of oral naltrexone was statistically significant in the presence of lofexidine tablet. The tmax was delayed for both naltrexone and 6ß-naltrexol (2-3 hours), and overall exposure was slightly reduced when naltrexone was administered with lofexidine tablet [see Drug Interactions (7.2)].

    Lofexidine tablet coadministered with paroxetine 
    In an open-label, single-sequence study of 24 healthy subjects, the strong CYP2D6 inhibitor paroxetine (40 mg/day) increased lofexidine tablet (0.36 mg) Cmax and AUC∞ by approximately 11% and 28%, respectively [see Drug Interactions (7.4)].


  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis , Mutagenesis , Impairment Of Fertility


    Carcinogenesis 
    No adequate long-term animal studies have been completed to evaluate the carcinogenic potential of lofexidine.



    Mutagenesis
    Lofexidine tested positive in the in vitro mouse lymphoma assay. Lofexidine tested negative in the in vitro bacterial reverse mutation assay (Ames assay) and in the in vivo rat micronucleus assay.



    Impairment of Fertility
    In a female fertility study in rabbits, fertility was not adversely impacted by administration of lofexidine hydrochloride up to 6.4 mg/kg/day (approximately 0.1 times the MRHD of 2.88 mg on an AUC basis) when administered orally to female rabbits starting 2 weeks prior to mating and through gestation and lactation. However, decreased breeding rate and higher post-implantation loss was observed at this dose, which correlated with higher resorptions and reduced litter size. Maternal toxicity, which included increased mortality rate, reduced body weight gain, and moderate sedation was observed at 6.4 mg/kg/day. The NOAEL for female fertility was 6.4 mg/kg/day and the NOAEL for female-mediated developmental parameters was 0.4 mg/kg/day (approximately 0.005 times the MRHD on an AUC basis).



    In a fertility study in rats, fertility was unaffected by administration of lofexidine up to 0.88 mg/kg/day (approximately 0.2 times the MRHD on an AUC basis) via diet to male and female rats prior to mating and to the dams through gestation and lactation. No evidence of maternal toxicity was observed. However, no assessment of sperm or reproductive organs were performed in this study.



    Reduced testes, epididymis, and seminiferous tubule weights, as well as delayed sexual maturation of males and females and decreases in the number of corpora lutea and implantations after mating, were noted in offspring of pregnant rats administered lofexidine hydrochloride orally from GD 6 through lactation at exposures less than the human exposure based on AUC comparisons.


  • 14 CLINICAL STUDIES

    Two randomized, double-blind, placebo-controlled trials supported the efficacy of lofexidine tablet.


    Study 1, NCT01863186 


    Study 1 was a 2-part efficacy, safety, and dose-response study conducted in the United States in patients meeting DSM-IV criteria for opioid dependence who were physically dependent on short-acting opioids (e.g., heroin, hydrocodone, oxycodone). The first part of the study was an inpatient, randomized, double-blind, placebo-controlled design consisting of 7 days of inpatient treatment (Days 1-7) with lofexidine tablet  2.16 mg total daily dose (0.54 mg 4 times daily) (n=229), lofexidine tablet 2.88 mg total daily dose (0.72 mg 4 times daily) (n=222), or matching placebo (n=151). Patients also had access to a variety of support medications for withdrawal symptoms (guaifenesin, antacids, dioctyl sodium sulfosuccinate, psyllium hydrocolloid suspension, bismuth sulfate, acetaminophen, and zolpidem). The second part of the study (Days 8-14) was an open-label design where all patients who successfully completed Days 1-7 were eligible to receive open-label treatment with variable-dose lofexidine tablet treatment (as determined by the investigator, but not to exceed 2.88 mg total daily dose) for up to an additional 7 days (Days 8-14) in either an inpatient or outpatient setting as determined by the investigator and the patient. No patient received lofexidine tablet for more than 14 days.
    The two endpoints to support efficacy were the mean Short Opiate Withdrawal Scale of Gossop (SOWS-Gossop) total score on Days 1 – 7 of treatment and the proportion of patients that completed 7 days of treatment. The SOWS-Gossop, a patient-reported outcome (PRO) instrument, evaluates the following opioid withdrawal symptoms: feeling sick, stomach cramps, muscle spasms/twitching, feeling of coldness, heart pounding, muscular tension, aches and pains, yawning, runny eyes and insomnia/problems sleeping. For each opioid withdrawal symptom, patients are asked to rate their symptom severity using four response options (none, mild, moderate, and severe). The SOWS-Gossop total score ranges from 0 to 30 where a higher score indicates a greater withdrawal symptom severity. The SOWS-Gossop was administered at baseline and once daily 3.5 hours after the first morning dose on Days 1 – 7.


    Of the randomized and treated patients, 28% of placebo patients, 41% of lofexidine tablet 2.16 mg, and 40% of lofexidine 2.88 mg patients completed 7 days of treatment. The difference in proportion in both lofexidine tablet groups was significant compared to placebo. See Figure 1. Patients in the placebo group were more likely to drop out of the study prematurely due to lack of efficacy than patients treated with lofexidine tablet.


    Figure 1: Completion of treatment period for Study 1

     

    lofexidine-fig-1

    The mean SOWS-Gossop scores for Days 1 – 7 were 8.8, 6.5, and 6.1 for placebo, lofexidine tablet 2.16 mg and lofexidine tablet 2.88 mg, respectively. Results are shown in Figure 2. The mean difference between lofexidine tablet 2.16 mg and placebo was -2.3 with a 95% CI of (-3.4, -1.2). The mean difference between lofexidine tablet 2.88 mg and placebo was -2.7 with a 95% CI of (-3.9, -1.6). They were both significant. Symptoms assessed on the SOWS-Gossop were recorded as absent or mild for almost all patients remaining to the end of the assessment period.

    Study 2, NCT00235729 

    This was an inpatient, randomized, multicenter, double-blind, placebo-controlled study carried out in the United States in patients meeting DSM-IV criteria for opioid dependence who were physically dependent on short-acting opioids (e.g., heroin, hydrocodone, oxycodone). Patients were treated with lofexidine  tablets (2.88 mg/day [0.72 mg four times daily]) or matching placebo for 5 days (Days 1-5). Patients also had access to a variety of support medications for withdrawal symptoms (guaifenesin, antacids, dioctyl sodium sulfosuccinate, psyllium hydrocolloid suspension, bismuth sulfate, acetaminophen, and zolpidem). All patients then received placebo on Days 6 and 7 and were discharged on Day 8.


    The two endpoints to support efficacy were the mean SOWS-Gossop total score on Days 1 – 5 of treatment and the proportion of patients that completed 5 days of treatment. The SOWS-Gossop was administered at baseline and once daily 3.5 hours after the first morning dose on Days 1 – 5.


    A total of 264 patients were randomized into the study. Of these, 134 patients were randomized to lofexidine  tablets 2.88 mg/day and 130 patients to placebo.
    Of the randomized and treated patients, 33% of placebo patients and 49% of lofexidine  tablets patients completed 5 days of treatment. The difference in proportion between the two groups was significant. SeeFigure 3. Patients in the placebo group were more likely to drop out of the study prematurely due to lack of efficacy than patients treated with lofexidine  tablets.

  • 17 PATIENT COUNSELING INFORMATION


    Advise the patient to read the FDA-approved patient labeling (Patient Information).
    Lofexidine tablets may mitigate, but not completely prevent, the symptoms associated with opioid withdrawal syndrome, which may include feeling sick, stomach cramps, muscle spasms or twitching, feeling of cold, heart pounding, muscular tension, aches and pains, yawning, runny eyes and sleep problems (insomnia). Patients should be advised that withdrawal will not be easy. Additional supportive measures should be clearly advised, as needed.

    Hypotension and Bradycardia


    Inform patients to be alert for any symptoms of low blood pressure or pulse (e.g., dizziness, lightheadedness, or feelings of faintness at rest or on abruptly standing). Advise patients on how to reduce the risk of serious consequences should hypotension occur (sit or lie down, carefully rise from a sitting or lying position).
    Patients being given lofexidine tablet in an outpatient setting should be capable of and instructed on self-monitoring for hypotension, orthostasis and bradycardia and advised to withhold lofexidine tablet doses and contact their healthcare provider for instructions if they experience these signs or related symptoms [see Warnings and Precautions (5.1)].

    Advise patients to avoid becoming dehydrated or overheated, which may potentially increase the risks of hypotension and syncope [see Warnings and Precautions (5.1)].


    Concomitant Medications
    Review with the patient all concomitant medications being taken and request that the patient immediately inform their healthcare provider of any changes in concomitant medications, including any other medications that may be used to treat individual symptoms of withdrawal.

    Increased Risk of CNS Depression with Concomitant use of CNS Depressant Drugs 
    Inform patients of the increased risk of CNS depression with concomitant use of benzodiazepines, alcohol, barbiturates, or other sedating drugs [see Warnings and Precautions (5.3)].
    Advise patients using lofexidine tablet in an outpatient setting that, until they learn how they respond to lofexidine tablet, they should be careful or avoid doing activities such as driving or operating heavy machinery. [see Warnings and Precautions (5.3)].

    Sudden Discontinuation of lofexidine tablet
    Inform patients not to discontinue lofexidine tablet without consulting their healthcare provider [see Warnings and Precautions (5.5)].

    Risk of Opioid Overdose After Discontinuation of Opioids
    Advise patients that after a period of not using opioid drugs, they may be more sensitive to the effects of opioids and at greater risk of overdosing [see Warnings and Precautions (5.4)].
