Imcivree

Last updated on RxList: 12/10/2020
Drug Description

What is IMCIVREE and how is it used?

  • IMCIVREE is a prescription medicine used in adults and children 6 years of age and older with obesity due to the genetic conditions proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency, to help them lose weight and keep the weight off.
  • Your healthcare provider should order a genetic test to confirm POMC, PCSK1, or LEPR deficiency before you start using IMCIVREE.
  • IMCIVREE is not for use in people with the following conditions because it may not work:
    • Obesity due to suspected POMC, PCSK1, or LEPR deficiency not confirmed by genetic testing (benign or likely benign result).
    • Other types of obesity not related to POMC, PCSK1, or LEPR deficiency, including obesity associated with other genetic conditions and general obesity.

It is not known if IMCIVREE is safe and effective in children under 6 years of age.

What are the possible side effects of IMCIVREE?

IMCIVREE may cause serious side effects, including:

  • Male and female sexual function problems. IMCIVREE can cause an erection that happens without any sexual activity in males (spontaneous penile erection) and unwanted sexual reactions (changes in sexual arousal that happen without any sexual activity) in females. If you have an erection lasting longer than 4 hours, get emergency medical help right away.
  • Depression and suicidal thoughts or actions. You or a caregiver should call your healthcare provider right away if you have any new or worsening symptoms of depression.
  • Increased skin pigmentation and darkening of skin lesions (moles or nevi) you already have. These changes happen because of how IMCIVREE works in the body and will go away when you stop using IMCIVREE. You should have a full body skin exam before starting and during treatment with IMCIVREE to check for skin changes.
  • Benzyl alcohol toxicity. Benzyl alcohol is a preservative in IMCIVREE. Benzyl alcohol can cause serious side effects, including death, in premature and low-birth weight infants, who have received medicines that contain benzyl alcohol. IMCIVREE should not be used in premature and low-birth weight infants.

The most common side effects of IMCIVREE include:

  • injection site reactions
  • darkening of the skin
  • nausea
  • headache
  • diarrhea
  • abdominal pain
  • back pain
  • fatigue
  • vomiting
  • depression
  • upper respiratory tract infection
  • erection that happens without any sexual activity in males

These are not all the possible side effects of IMCIVREE.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or Rhythm Pharmaceuticals at 1-833-789-6337.

Each 1 mL of IMCIVREE contains 10 mg of setmelanotide provided as setmelanotide acetate, which is a salt with 2 to 4 molar equivalents of acetate, and the following inactive ingredients: 100 mg N-(carbonyl-methoxypolyethylene glycol 2000)-1,2-distearoyl-glycero-3phosphoethanolamine sodium salt, 8 mg carboxymethylcellulose sodium (average MWt 90,500), 11 mg mannitol, 5 mg phenol, 10 mg benzyl alcohol, 1 mg edetate disodium dihydrate, and Water for Injection. The pH of IMCIVREE is 5 to 6.

Indications & Dosage

INDICATIONS

IMCIVREE is indicated for chronic weight management in adult and pediatric patients 6 years of age and older with obesity due to proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency confirmed by genetic testing demonstrating variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS).

Limitations Of Use

IMCIVREE is not indicated for the treatment of patients with the following conditions as IMCIVREE would not be expected to be effective:

  • Obesity due to suspected POMC, PCSK1, or LEPR deficiency with POMC, PCSK1, or LEPR variants classified as benign or likely benign
  • Other types of obesity not related to POMC, PCSK1 or LEPR deficiency, including obesity associated with other genetic syndromes and general (polygenic) obesity

DOSAGE AND ADMINISTRATION

Patient Selection

  • Select patients for treatment with IMCIVREE who have genetically confirmed or suspected deficiency of POMC, PCSK1, or LEPR [see Clinical Studies].
  • Treat patients with variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS) in the clinical context of the patient [see Clinical Studies].
  • Currently available tests for the detection of variants in the POMC, PCSK1, or LEPR genes have not been approved or cleared by the FDA.

Dosage In Adults And Pediatric Patients 12 Years Of Age And Older

  • The starting dose of IMCIVREE is 2 mg (0.2 mL) injected subcutaneously once daily for 2 weeks. Monitor patients for gastrointestinal (GI) adverse reactions [see ADVERSE REACTIONS].
  • If the starting dose is not tolerated, reduce to 1 mg (0.1 mL) once daily. If the 1 mg once daily dose is tolerated and additional weight loss is desired, titrate to 2 mg (0.2 mL) once daily.
  • If the 2 mg daily dose is tolerated and additional weight loss is desired, increase the dose to 3 mg (0.3 mL) once daily. If the 3 mg once daily dose is not tolerated, maintain administration of 2 mg (0.2 mL) once daily.

Dosage In Pediatric Patients 6 To Less Than 12 Years Of Age

  • For pediatric patients aged 6 to less than 12 years, the starting dose of IMCIVREE is 1 mg (0.1 mL) injected subcutaneously once daily for 2 weeks. Monitor patients for GI adverse reactions [see ADVERSE REACTIONS].
  • If the starting dose is not tolerated, reduce to 0.5 mg (0.05 mL) once daily. If the 0.5 mg once daily dose is tolerated and additional weight loss is desired, the dose may be increased to 1 mg (0.1 mL) once daily.
  • If the 1 mg dose is tolerated, increase the dose to 2 mg (0.2 mL) once daily.
  • If the 2 mg once daily dose is not tolerated, reduce to 1 mg (0.1 mL) once daily. If the 2 mg once daily dose is tolerated and additional weight loss is desired, the dose may be increased to 3 mg (0.3 mL) once daily.

Monitoring

  • Periodically assess response to IMCIVREE therapy. In pediatric patients, evaluate the impact of weight loss on growth and maturation.
  • Evaluate weight loss after 12-16 weeks of treatment. If a patient has not lost at least 5% of baseline body weight or 5% of baseline BMI for patients with continued growth potential, discontinue IMCIVREE as it is unlikely that the patient will achieve and sustain clinically meaningful weight loss with continued treatment.

Administration Instructions

  • Prior to initiation of IMCIVREE, train patients on proper injection technique. Instruct patients to use a 1-mL syringe with a 28-or 29-gauge needle appropriate for subcutaneous injection.
  • Inspect IMCIVREE visually before use. It should appear clear to slightly opalescent, colorless to slightly yellow. Do not use if particulate matter or discoloration is seen.
  • Remove IMCIVREE from the refrigerator approximately 15 minutes prior to administration. Alternatively, warm IMCIVREE prior to administration by rolling the vial gently between the palms of the hands for 60 seconds.
  • Administer IMCIVREE once daily, at the beginning of the day, without regard to meals.
  • Inject IMCIVREE subcutaneously in the abdomen, thigh, or arm, rotating to a different site each day. Do not administer IMCIVREE intravenously or intramuscularly.
  • If a dose is missed, resume the once daily regimen as prescribed with the next scheduled dose.

Side Effects & Drug Interactions

SIDE EFFECTS

The following clinically significant adverse reactions are described elsewhere in the labeling:

  • Spontaneous Penile Erection [see WARNINGS AND PRECAUTIONS]
  • Depression and Suicidal Ideation [see WARNINGS AND PRECAUTIONS]
  • Skin Pigmentation and Darkening of Pre-Existing Nevi [see WARNINGS AND PRECAUTIONS]

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 rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of IMCIVREE was evaluated in two 52-week, open-label clinical studies of 27 patients with obesity due to POMC, PCSK1, or LEPR deficiency with POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance [see Clinical Studies].

Table 1 summarizes the adverse reactions that occurred in the open-label studies during the first 52 weeks of treatment in 3 or more patients treated with IMCIVREE.

e n = 13 male patients

In a 12-week, placebo-controlled clinical study in an unapproved population, 4 female patients (7%) treated with IMCIVREE experienced sexual adverse reactions compared to 0 patients in the placebo group; 3 experienced a disturbance in sexual arousal and one experienced hypersensitivity of the labia.

Immunogenicity

As with all peptides, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.

Approximately 61% of adult and pediatric patients with POMC-or LEPR-deficiency who received IMCIVREE (N=28) screened positive for antibodies to IMCIVREE, and 39% screened negative. The 61% of patients who screened positive for antibodies to IMCIVREE were inconclusive for antibodies to IMCIVREE in the confirmatory assay. There was no observation of a rapid decline in IMCIVREE concentrations to suggest the presence of anti-drug antibodies.

Approximately 13% of adult and pediatric patients with LEPR-deficiency (3 patients) confirmed positive for antibodies to alpha-MSH that were classified as low-titer and non-persistent. Of these 3 patients (13%), 2 tested positive post-IMCIVREE treatment and 1 was positive pretreatment. None of the patients with POMC-deficiency were confirmed to have antibodies to alpha-MSH.

DRUG INTERACTIONS

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Disturbance In Sexual Arousal

Sexual adverse reactions may occur in patients treated with IMCIVREE. Spontaneous penile erections in males (23%) and sexual adverse reactions in females (7% in IMCIVREE-treated patients and 0% in placebo-treated patients from an unapproved population) occurred in clinical studies with IMCIVREE [see ADVERSE REACTIONS].

Inform patients that these events may occur and instruct patients who have an erection lasting longer than 4 hours to seek emergency medical attention.

Depression And Suicidal Ideation

Some drugs that target the central nervous system, such as IMCIVREE, may cause depression or suicidal ideation. Patients with a history of severe depression were excluded from IMCIVREE clinical studies. Depression (26%) and suicidal ideation (11%) occurred in IMCIVREE clinical studies [see ADVERSE REACTIONS].

Monitor patients for new onset or worsening of depression. Consider discontinuing IMCIVREE if patients experience suicidal thoughts or behaviors.

Skin Pigmentation And Darkening Of Pre-Existing Nevi

IMCIVREE may cause generalized increased skin pigmentation and darkening of pre-existing nevi due to its pharmacologic effect. Skin hyperpigmentation occurred in 21 patients (78%) of patients treated with IMCIVREE [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. This effect is reversible upon discontinuation of the drug.

Perform a full body skin examination prior to initiation and periodically during treatment with IMCIVREE to monitor pre-existing and new skin pigmentary lesions.

Risk Of Serious Adverse Reactions Due To Benzyl Alcohol Preservative In Neonates And Low Birth Weight Infants

IMCIVREE is not approved for use in neonates or infants. Serious and fatal adverse reactions including “gasping syndrome” can occur in neonates and low birth weight infants treated with benzyl alcohol-preserved drugs. The “gasping syndrome” is characterized by central nervous system depression, metabolic acidosis, and gasping respirations. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known (IMCIVREE contains 10 mg of benzyl alcohol per mL) [see Use In Specific Populations].

Patient Counseling Information

Advise the patient or caregiver to read the FDA-approved patient labeling (Instructions for Use).

Spontaneous Penile Erection

Inform male patients that spontaneous erection may occur with IMCIVREE treatment. Advise patients to seek appropriate medical treatment if an erection lasts longer than 4 hours [see WARNINGS AND PRECAUTIONS].

Depression And Suicidal Ideation

Inform patients or caregivers that some drugs that target the central nervous system, such as IMCIVREE, may cause depression or suicidal ideation. Advise patients or caregivers to report any new or worsening symptoms of depression [see WARNINGS AND PRECAUTIONS].

Skin Pigmentation And Darkening Of Pre-Existing Nevi

Inform patients or caregivers that skin darkening occurs in the majority of patients treated with IMCIVREE because of its mechanism of action. This change is reversable upon discontinuation of IMCIVREE. Inform patients or caregivers that they should have a full body skin examination before starting and during treatment with IMCIVREE to monitor these changes [see WARNINGS AND PRECAUTIONS].

Pregnancy

Advise patients who may become pregnant to inform their healthcare provider of a known or suspected pregnancy [see Use In Specific Populations].

Lactation

Advise patients that treatment with IMCIVREE is not recommended while breastfeeding [see Use In Specific Populations].

Administration

Instruct patients and caregivers how to prepare and administer the correct dose of IMCIVREE and assess their ability to inject subcutaneously to ensure the proper administration of IMCIVREE. Instruct patients to use a 1 mL syringe with a 28-or 29-gauge needle appropriate for subcutaneous injection.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Long term studies in animals have not been performed to evaluate the carcinogenic potential of setmelanotide.

Setmelanotide was not mutagenic or clastogenic in a bacterial reverse mutation test, an in vitro chromosome aberration test in human lymphocyte cultures, or an in vivo bone marrow micronucleus study in rats.

There were no effects on the fertility of male rats subcutaneously administered up to 3.0 mg/kg/day setmelanotide, which represents 9 times the MRHD of 3 mg, based on AUC. No effects on the fertility of female rats were observed with subcutaneous administration up to 5 mg/kg/day setmelanotide, which represents 11 times the MRHD of 3 mg, based on AUC.

Use In Specific Populations

Pregnancy

Risk Summary

Discontinue IMCIVREE when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus.

IMCIVREE contains the preservative benzyl alcohol. Because benzyl alcohol is rapidly metabolized by a pregnant woman, benzyl alcohol exposure in the fetus is unlikely. However, adverse reactions have occurred in premature neonates and low birth weight infants who received intravenously administered benzyl alcohol-containing drugs [see WARNINGS AND PRECAUTIONS and Pediatric Use].

There are no available data with IMCIVREE in pregnant women to inform a drug-associated risk for major birth defects and miscarriage, or adverse maternal or fetal outcomes. For the general US population, weight loss offers no potential benefit to a pregnant woman and may result in fetal harm (see Clinical Considerations). In animal reproduction studies, setmelanotide subcutaneously administered to pregnant rats from before mating to the end of organogenesis was not teratogenic at doses 11 times the maximum recommended human dose (MRHD) of 3 mg. Setmelanotide subcutaneously administered to pregnant rabbits during the period of organogenesis was not teratogenic at clinical doses. Setmelanotide administered subcutaneously to pregnant rats during organogenesis through lactation did not result in adverse developmental effects at doses 7 times the MRHD (see Data).

The estimated background risk of birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk

Maternal obesity increases the risk for congenital malformations, including neural tube defects, cardiac malformations, oral clefts, and limb reduction defects. In addition, weight loss during pregnancy may result in fetal harm including increased risk of small for gestational age. Appropriate weight gain based on pre-pregnancy weight is currently recommended for all pregnant women, including those who are already overweight or obese, due to the obligatory weight gain that occurs in maternal tissues during pregnancy.

Data

Animal Data

Embryo-fetal development was evaluated in female rats administered setmelanotide subcutaneously during mating to end of major organogenesis (14 days prior to mating to gestation day 17) at doses of 0.5, 3, and 5 mg/kg/day, resulting in exposures up to 11 times the human exposure at MRHD of 3 mg, based on AUC. Dose-related decreases in maternal food intake and body weight gain were observed during the premating period but not during gestation. No evidence of embryo-fetal toxicity was observed.

Embryo-fetal development was evaluated in pregnant rabbits subcutaneously administered setmelanotide during organogenesis (gestation days 7 to 19) at doses of 0.05, 0.1, and 0.2 mg/kg/day, resulting in clinically relevant exposures at the MRHD, based on AUC. Decreases in maternal food consumption and body weight were observed at all doses. Increases in embryo-fetal resorptions and post-implantation losses were observed at ≥0.1 mg/kg/day in the presence of significant maternal toxicity, and fetal body weights were 7% lower than controls at 0.2 mg/kg/day.

Pre-and post-natal development was evaluated in rats subcutaneously administered setmelanotide during organogenesis and continuing to weaning (gestation day 6 to lactation day 21) at doses of 0.5, 3.0, and 5.0 mg/kg/day, which resulted in exposures up to 7 times the human exposure at the MRHD, based on AUC. Pup body weights at birth were 9% lower than controls at 3.0 and 5.0 mg/kg/day, which was consistent with reduced maternal body weight gain and food consumption during gestation. No adverse setmelanotide-related effects on pup survival, growth, maturation, visual function, neurobehavioral performance, or reproductive performance were observed up to the highest dose.

Lactation

Risk Summary

Treatment with IMCIVREE is not recommended for use while breastfeeding.

IMCIVREE from multiple-dose vials contains the preservative benzyl alcohol. Because benzyl alcohol is rapidly metabolized by a lactating woman, benzyl alcohol exposure in the breastfed infant is unlikely. However, adverse reactions have occurred in premature neonates and low birth weight infants who received intravenously administered benzyl alcohol-containing drugs [see WARNINGS AND PRECAUTIONS and Pediatric Use].

There is no information on the presence of setmelanotide or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. However, setmelanotide is present in the milk of rats (see Data). When a drug is present in rat milk, it is likely that the drug will be present in human milk.

Data

Dose-related setmelanotide concentrations were observed in milk 2 hours after subcutaneous injection in the preweaning phase of a pre-and post-natal development study in rats. No quantifiable setmelanotide concentrations were detected in plasma from nursing pups on postnatal Day 11.

Pediatric Use

The safety and effectiveness of IMCIVREE for obesity due to POMC, PCSK1, or LEPR deficiency have been established in pediatric patients aged 6 years and older. Use of IMCIVREE for this indication is supported by evidence from 2 open-label studies that included 9 pediatric patients [see Clinical Studies].

The safety and effectiveness of IMCIVREE have not been established in pediatric patients younger than 6 years old.

IMCIVREE is not approved for use in neonates or infants. Serious adverse reactions including fatal reactions and the “gasping syndrome” occurred in premature neonates and low birth weight infants in the neonatal intensive care unit who received drugs containing benzyl alcohol as a preservative. In these cases, benzyl alcohol dosages of 99 to 234 mg/kg/day produced high levels of benzyl alcohol and its metabolites in the blood and urine (blood levels of benzyl alcohol were 0.61 to 1.378 mmol/L). Additional adverse reactions included gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Preterm, low-birth weight infants may be more likely to develop these reactions because they may be less able to metabolize benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known (IMCIVREE contains 10 mg of benzyl alcohol) [see WARNINGS AND PRECAUTIONS].

Geriatric Use

Clinical studies of IMCIVREE did not include patients aged 65 and over. It is not known whether they respond differently from younger patients.

Renal Impairment

Population pharmacokinetic analysis suggests decreased clearance in patients with renal impairment. The majority of patients in the clinical studies had normal renal function.

No dose adjustments for patients with mild renal impairment (estimated glomerular filtration rate (eGFR) of 60-89 mL/min/1.73 m2) are needed. IMCIVREE is not recommended for use in patients with moderate (eGFR 30-59 mL/min/1.73 m2) and severe renal impairment (eGFR 15-29 mL/min/1.73 m2) and end stage renal disease (eGFR less than 15 mL/min/1.73 m2).

Overdosage & Contraindications

OVERDOSE

In the event of an overdose initiate appropriate supportive treatment according to the patient’s clinical signs and symptoms.

CONTRAINDICATIONS

None

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Setmelanotide is an MC4 receptor agonist with 20-fold less activity at the melanocortin 3 (MC3) and melanocortin 1 (MC1) receptors. MC4 receptors in the brain are involved in regulation of hunger, satiety, and energy expenditure. In patients with obesity due to POMC, PCSK1, and LEPR deficiency associated with insufficient activation of the MC4 receptor, setmelanotide may re-establish MC4 receptor pathway activity to reduce hunger and promote weight loss through decreased caloric intake and increased energy expenditure. Nonclinical evidence shows that MC4 receptors are important for setmelanotide-regulated appetite and weight loss. The MC1 receptor is expressed on melanocytes, and activation of this receptor leads to accumulation of melanin and increased skin pigmentation independently of ultraviolet light [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS].

Pharmacodynamics

Energy Expenditure

Short-term administration of IMCIVREE in 12 healthy obese patients increased resting energy expenditure and shifted substrate oxidation to fat.

Blood Pressure And Heart Rate

No clinically significant increases in blood pressure (BP) or heart rate (HR) were observed following administration of IMCIVREE to healthy obese patients or patients with monogenic obesity.

Pharmacokinetics

The mean steady state setmelanotide Cmax,ss, AUCtau, and trough concentration for a 3-mg dose administered subcutaneously once daily was 37.9 ng/mL, 495 h*ng/mL, and 6.77 ng/mL, respectively. Steady-state plasma concentrations of setmelanotide were achieved within 2 days with daily dosing of 1-3 mg setmelanotide. The accumulation of setmelanotide in the systemic circulation during once-daily dosing over 12 weeks was approximately 30%. Setmelanotide AUC and Cmax increased proportionally following multiple-dose subcutaneous administration in the proposed dose range (1-3 mg).

Absorption

After subcutaneous injection of IMCIVREE, plasma concentrations of setmelanotide reached maximum concentrations at a median tmax of 8 h after dosing.

Distribution

The mean apparent volume of distribution of setmelanotide after subcutaneous administration of IMCIVREE 3 mg once daily was estimated from the population pharmacokinetics model to be 48.7 L. Protein binding of setmelanotide is 79.1%.

Elimination

The effective elimination half-life (t½) of setmelanotide was approximately 11 hours. The total apparent steady state clearance of setmelanotide following subcutaneous administration of IMCIVREE 3 mg once daily was estimated from the population PK model to be 4.86 L/h.

Metabolism

Setmelanotide is expected to be metabolized into small peptides by catabolic pathways.

Excretion

Approximately 39% of the administered setmelanotide dose was excreted unchanged in urine during the 24-hour dosing interval following subcutaneous administration of 3 mg once daily.

Specific Populations

No clinically significant differences in the pharmacokinetics of setmelanotide were observed based on sex. The effect of age 65 years or older, pregnancy, or hepatic impairment on the pharmacokinetics of setmelanotide is unknown.

Pediatric Patients

IMCIVREE has been evaluated in pediatric patients aged 6 to less than 12 years and aged 12 to 17 years. Simulations from the population pharmacokinetic analyses suggest that AUC and Cmax are 100% and 92% higher in pediatric patients 6 to less than 12 years as compared to patients greater than or equal to 17 years. For patients aged 12 to 17 years, the setmelanotide AUC and Cmax were 44% and 37% higher, respectively as compared to patients greater than or equal to 17 years. [see DOSAGE AND ADMINISTRATION].

Patients With Renal Impairment

Population pharmacokinetic analysis suggests a 19% higher setmelanotide AUC in patients with mild renal impairment as compared to patients with normal renal function [see Use In Specific Populations].

Drug Interaction Studies

In Vitro Assessment Of Drug-Drug Interactions

Setmelanotide has low potential for pharmacokinetic drug-drug interactions related to cytochrome P450 (CYP), transporters and plasma protein binding.

In Vivo Assessment Of Drug-Drug Interactions

No clinical studies evaluating the drug-drug interaction potential of setmelanotide have been conducted.

Clinical Studies

The safety and efficacy of IMCIVREE for chronic weight management in patients with obesity due to POMC, PCSK1, and LEPR deficiency were assessed in 2 identically designed, 1-year, open-label studies, each with an 8-week, double-blind withdrawal period. Study 1 (NCT02896192) enrolled patients aged 6 years and above with obesity and genetically confirmed or suspected POMC or PCSK1 deficiency, and Study 2 (NCT03287960) enrolled patients aged 6 years and above with obesity and genetically confirmed or suspected LEPR deficiency. In both studies, the local genetic testing results were centrally confirmed using Sanger sequencing. The studies enrolled patients with homozygous or presumed compound heterozygous pathogenic, likely pathogenic variants, or VUS for either the POMC or PCSK1 genes (Study 1) or the LEPR gene (Study 2). Patients with double heterozygous variants in 2 different genes were not eligible for treatment with IMCIVREE. In both studies, adult patients had a body mass index (BMI) of ≥30 kg/m2. Weight in pediatric patients was ≥95th percentile using growth chart assessments.

Dose titration occurred over a 2-to 12-week period, followed by a 10-week, open-label treatment period. Patients who achieved at least a 5-kilogram weight loss (or at least 5% weight loss if baseline body weight was <100 kg) at the end of the open-label treatment period continued into a double-blind withdrawal period lasting 8 weeks, including 4 weeks of IMCIVREE followed by 4 weeks of placebo (investigators and patients were blinded to this sequence). Following the withdrawal sequence, patients re-initiated active treatment with IMCIVREE at the therapeutic dose for up to 32 weeks.

Efficacy analyses were conducted in 21 patients (10 in Study 1 and 11 in Study 2) who had completed at least 1 year of treatment at the time of a prespecified data cutoff. Six additional patients enrolled in the studies (4 in Study 1 and 2 in Study 2) who had not yet completed 1 year of treatment at the time of the cutoff were not included the efficacy analyses.

Of the 21 patients included in the efficacy analysis in Studies 1 and 2, 62% were adults and 38% were aged 16 years or younger. In Study 1, 50% of patients were female, 70% were White, and the median BMI was 40.0 kg/m2 (range: 26.6-53.3) at baseline. In Study 2, 73% of patients were female, 91% were White, and the median BMI was 46.6 kg/m2 (range: 35.8-64.6) at baseline.

Effect Of IMCIVREE On Body Weight

In Study 1, 80% of patients with obesity due to POMC or PCSK1 deficiency met the primary endpoint, achieving a ≥10% weight loss after 1 year of treatment with IMCIVREE. In Study 2, 46% of patients with obesity due to LEPR deficiency achieved a ≥10% weight loss after 1 year of treatment with IMCIVREE (Table 2).

When treatment with IMCIVREE was withdrawn in the 16 patients who had lost at least 5 kg (or 5% of body weight if baseline body weight was <100 kg) during the 10-week open-label period, these patients gained an average of 5.5 kg in Study 1 and 5.0 kg in Study 2 over 4 weeks. Re-initiation of treatment with IMCIVREE resulted in subsequent weight loss (see Figure 1).

Effect Of IMCIVREE On Hunger

Patients 12 years and older self-reported their daily maximal hunger in a diary, assessed by the Daily Hunger Questionnaire Item 2. Hunger was scored on an 11-point scale from 0 (“not hungry at all”) to 10 (“hungriest possible”). Weekly means of daily hunger scores at Baseline and Week 52 are summarized in Table 4.

Note: This analysis includes patients aged 12 years and older who received at least 1 dose of study drug and had available data. One patient in Study 2 had missing hunger data at Week 52.
Hunger score was captured in a daily diary and was averaged to calculate a weekly score for analysis. Hunger ranged from 0 to 10 on an 11-point scale where 0 = “not hungry at all” and 10 = “hungriest possible.”

Hunger scores generally worsened during the double-blind, placebo withdrawal period among those patients who had experienced an improvement from baseline, and scores improved when IMCIVREE was reinitiated.

Supportive of IMCIVREE’s effect on weight loss, there were general numeric improvements in cardiometabolic parameters, such as blood pressure, lipids, glycemic parameters, and waist circumference. However, because of the limited number of patients studied and the lack of a control group, the treatment effects on these parameters could not be accurately quantified.

Medication Guide

PATIENT INFORMATION

IMCIVREE™
[im-SIV-ree]
(setmelanotide) injection, for subcutaneous use

What is IMCIVREE?

  • IMCIVREE is a prescription medicine used in adults and children 6 years of age and older with obesity due to the genetic conditions proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency, to help them lose weight and keep the weight off.
  • Your healthcare provider should order a genetic test to confirm POMC, PCSK1, or LEPR deficiency before you start using IMCIVREE.
  • IMCIVREE is not for use in people with the following conditions because it may not work:
    • Obesity due to suspected POMC, PCSK1, or LEPR deficiency not confirmed by genetic testing (benign or likely benign result).
    • Other types of obesity not related to POMC, PCSK1, or LEPR deficiency, including obesity associated with other genetic conditions and general obesity.

It is not known if IMCIVREE is safe and effective in children under 6 years of age.

Before using IMCIVREE, tell your healthcare provider about all your medical conditions, including if you:

  • have or have had areas of darkened skin, including skin discoloration (hyperpigmentation).
  • have or have had depression, or suicidal thoughts or behavior.
  • have kidney problems.
  • are pregnant or planning to become pregnant. Losing weight while pregnant may harm your unborn baby. Your healthcare provider may stop your treatment with IMCIVREE if you become pregnant. Tell your healthcare provider if you become pregnant or think you might be pregnant during treatment with IMCIVREE.
  • are breastfeeding or plan to breastfeed. It is not known if IMCIVREE passes into your breastmilk. You should not breastfeed during treatment with IMCIVREE.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

How should I use IMCIVREE?

  • See the detailed Instructions for Use to learn how to prepare and inject IMCIVREE.
  • IMCIVREE is given as an injection under your skin (subcutaneous) by you or a caregiver.
  • A healthcare provider should show you or your caregiver how to prepare and inject your dose of IMCIVREE before injecting for the first time. Do not try to inject IMCIVREE unless you have been trained by a healthcare provider.
  • Use IMCIVREE exactly as prescribed by your healthcare provider.
  • Your healthcare provider may tell you to stop using IMCIVREE if you have not lost a certain amount of weight after 12 to 16 weeks of treatment.
  • IMCIVREE should be injected 1 time each day when you first wake up. IMCIVREE can be given with or without food.
  • If you miss a dose of IMCIVREE, inject your next dose at the regularly scheduled time the next day.

What are the possible side effects of IMCIVREE?

IMCIVREE may cause serious side effects, including:

  • Male and female sexual function problems. IMCIVREE can cause an erection that happens without any sexual activity in males (spontaneous penile erection) and unwanted sexual reactions (changes in sexual arousal that happen without any sexual activity) in females. If you have an erection lasting longer than 4 hours, get emergency medical help right away.
  • Depression and suicidal thoughts or actions. You or a caregiver should call your healthcare provider right away if you have any new or worsening symptoms of depression.
  • Increased skin pigmentation and darkening of skin lesions (moles or nevi) you already have. These changes happen because of how IMCIVREE works in the body and will go away when you stop using IMCIVREE. You should have a full body skin exam before starting and during treatment with IMCIVREE to check for skin changes.
  • Benzyl alcohol toxicity. Benzyl alcohol is a preservative in IMCIVREE. Benzyl alcohol can cause serious side effects, including death, in premature and low-birth weight infants, who have received medicines that contain benzyl alcohol. IMCIVREE should not be used in premature and low-birth weight infants.

The most common side effects of IMCIVREE include:

  • injection site reactions
  • darkening of the skin
  • nausea
  • headache
  • diarrhea
  • abdominal pain
  • back pain
  • fatigue
  • vomiting
  • depression
  • upper respiratory tract infection
  • erection that happens without any sexual activity in males

These are not all the possible side effects of IMCIVREE.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or Rhythm Pharmaceuticals at 1-833-789-6337.

General information about the safe and effective use of IMCIVREE.

Medicines are sometimes prescribed for purposes other than those listed in a Patient Information leaflet. Do not use IMCIVREE for a condition for which it was not prescribed. Do not give IMCIVREE to other people, even if they have the same symptoms that you have. It may harm them. You can ask your pharmacist or healthcare provider for information about IMCIVREE that is written for health professionals.

Injecting IMCIVREE

Step 5 - Prepare your injection site.

  • Choose the area where you will give the injection. Choose from the following recommended injection sites:
    • belly (abdomen) (Figure M)
    • front of the middle thighs (Figure N)
    • back of the upper arm (Figure O)
  • Be sure to choose an area on the belly (abdomen) at least 2 inches from the belly button.
  • Do not inject into the belly button, ribs, and hip bones, as well as scars or moles.
  • Do not inject in an area that is red, swollen, or irritated

Figure M

Injection site: belly (abdomen) - Illustration

Figure N

Injection site: front of the middle thighs - Illustration

Figure O

Injection site: back of the upper arm - Illustration

  • Clean the injection site with the second alcohol wipe using a circular motion.
  • Do not touch, fan, or blow on the cleaned area.
  • Allow the skin to dry for about 10 seconds.

Rotate your injection site each day.

You should use a different injection site each time you give an injection, at least 1 inch away from the area you used for your previous injection. You may want to use a calendar or diary to record your injection sites.

Step 6 - Place your hands for the injection.

  • With 1 hand, pinch about 2 inches of skin at the injection site between yourthumb and index (pointer) finger (Figure P). Pinching the skin is important to help make sure that you inject the medicine under the skin (into fatty tissue) but not any deeper (into the muscle).

Step 7 - Inject and release.

  • With your other hand, place the syringe between the thumb andindex (pointer) finger.
  • Hold the middle of the syringe (where the markings are printed) at a 90-degree angle to your body and push the needle straight into the injection site (Figure Q). Make sure that you push the needle all the way into the skin.
  • Do not hold or push on the plunger while inserting the needle.

Figure Q

Hold the middle of the syringe (where the markings are printed) at a 90-degree angle to your body and push the needle straight into the injection site - Illustration

  • Slowly push the plunger down to inject the medicine (Figure R)
  • Keep the needle in your skin and count to 5 to make sure that all the medicine is given.
  • Let go of the pinched skin and remove the needle.
  • Use the gauze pad to gently apply pressure to the injection site.
  • Do not recap the needle.

Tips for giving injections to children

When giving a child an injection, it can help to have the child do other things. Have the child:

  • squeeze something soft like a ball or stuffed animal.
  • slowly breathe in and out.
  • sing a song, count, or name favorite colors or animals.

Storing IMCIVREE

  • Store unopened and opened vials in the original carton to protect them from light.
  • Store opened vials of IMCIVREE in the refrigerator between 36°F to 46°F (2°C to 8°C). If needed, vials may be removed from the refrigerator and stored at temperatures ranging from refrigerated to room temperature (36°F to 77°F (2°C to 25°C)), and vials may be returned to the refrigerator. Brief temperature excursions up to 86°F (30°C) are permitted. Throw away all opened vials 30 days after first opening, even if some medicine is still left in the vial.
  • Unopened vials of IMCIVREE may be stored in the refrigerator between 36°F to 46°F (2°C to 8°C) until the expiration date. If needed, unopened vials may also be removed from the refrigerator and stored at temperatures ranging from refrigerated to room temperature (36°F to 77°F (2°C to 25°C)) for up to 30 days. Vials may be returned to the refrigerator. Brief storage temperature excursions up to 86°F (30°C) are permitted. Throw away IMCIVREE if it has been more than 30 days since the vial was first removed from the refrigerator.
  • If necessary, vials may be stored at room temperature below 86°F (30° C) and may be returned to refrigerated conditions. Write the date on the carton when you first open the vial.
