Question 1

What is IMCIVREE indicated for?

Accepted Answer

IMCIVREE is indicated for chronic weight management in adult and pediatric patients 6 years of age and older with monogenic or syndromic obesity due to: Pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency as determined by an FDA-approved test demonstrating variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS). Bardet-Biedl syndrome (BBS). 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 or BBS, including obesity associated with other genetic syndromes and general (polygenic) obesity. Rhythm’s companion diagnostic device (or CDx) is approved by the FDA and is used to identify people who are appropriate for treatment with IMCIVREE based on a genetic confirmation of POMC, PCSK1, or LEPR deficiency.

Question 2

Are there any contraindications to IMCIVREE?

Accepted Answer

No. There are no contraindications to IMCIVREE.¹

Question 3

How do I acquire a genetic test for my patients?

Accepted Answer

IMCIVREE is indicated for chronic weight management in patients 6 years of age and older with obesity due to POMC, PCSK1, or LEPR deficiency confirmed by an FDA-approved test. These diseases are biallelic, signifying that variants are present in both copies of the gene, and therefore include both homozygous and compound heterozygous forms. Rhythm’s companion diagnostic device (or CDx) is approved by the FDA and is used to identify people who are appropriate for treatment with IMCIVREE based on a genetic confirmation of POMC, PCSK1, or LEPR deficiency. For more information about acquiring this FDA-approved genetic test, please visit rhythm.preventiongenetics.com.

Question 5

How is IMCIVREE administered?

Accepted Answer

IMCIVREE is administered by subcutaneous injection, once daily, at the beginning of each day without regard to meals. The process for subcutaneous injection is described in the Instructions for Use, which contains complete administration instructions with illustrations.

Question 6

What part of the body should patients inject IMCIVREE into?

Accepted Answer

IMCIVREE should be injected subcutaneously in the abdomen, thigh, or arm, rotating to a different site each day. (Refer to Step 5 of the Instructions for Use.) Do not administer IMCIVREE intravenously or intramuscularly.

Question 7

What type of syringe should the patient use to administer IMCIVREE?

Accepted Answer

Prior to initiation of IMCIVREE, train patients or their caregivers on proper injection technique. Instruct patients to use a 1-mL syringe with a 28- or 29-gauge needle appropriate for subcutaneous injection.

Question 8

My patient missed a dose. Does he/she need to retitrate their dose?

Accepted Answer

If a dose is missed, the once-daily regimen should be resumed as prescribed with the next scheduled dose.

Question 9

My patient discontinued treatment for an extended period of time. Do I need to retitrate the dose?

Accepted Answer

No. Dose titration is only recommended to initially assess tolerability to the medication. In clinical studies, patients were placed on placebo for a 4-week period, then reinitiated therapy at their therapeutic dose for the remainder of the study.

Question 10

My patient accidentally administered an overdose of IMCIVREE. What adverse events should we be most concerned about?

Accepted Answer

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

Question 11

What were the most common adverse events observed in the clinical trials?

Accepted Answer

The most common adverse reactions (incidence ≥20%) included skin hyperpigmentation, injection site reactions, nausea, headache, diarrhea, abdominal pain, vomiting, depression, and spontaneous penile erection. Injection site reactions, nausea, and vomiting tended to occur within the first month after starting treatment, and then diminished over time. Changes in skin pigmentation/hair color are primarily reported within the first month of treatment, then become more gradual or stabilize afterward.

Question 12

What is hyperpigmentation? Is it just skin darkening?

Accepted Answer

Hyperpigmentation can involve the darkening of skin and pre-existing nevi in the absence of ultraviolet (UV) exposure.

Question 13

Is skin darkening reversible?

Accepted Answer

Generalized increased skin pigmentation occurred in the majority of patients (69%) treated with IMCIVREE in clinical trials. IMCIVREE may also cause darkening of pre-existing nevi due to its pharmacologic effect. This effect is reversible upon discontinuation of the drug.

Question 14

Why does my patient need a skin examination before starting IMCIVREE?

Accepted Answer

IMCIVREE is an MC4 receptor agonist with some activity at the melanocortin-1 (MC1) receptors; activation of MC1 leads to accumulation of melanin and increased skin pigmentation. Hyperpigmentation was reversible upon discontinuation of IMCIVREE in clinical trials. Perform a full body skin examination prior to initiation and periodically during treatment with IMCIVREE to monitor pre-existing and new skin pigmentary lesions.

Question 15

Can IMCIVREE cause skin cancer?

Accepted Answer

There were no reports of melanoma related to the observed hyperpigmentation in clinical trials of IMCIVREE.

Question 16

Does IMCIVREE cause or worsen depression?

Accepted Answer

Patients with a history of severe depression were excluded from the clinical trials. Some drugs that target the central nervous system, such as IMCIVREE, may cause depression or suicidal ideation. Depression (26%) and suicidal ideation (11%) occurred in adults and pediatric patients in IMCIVREE clinical studies. Patients with a history of depression or suicidal ideation may be at increased risk for recurrent episodes while taking IMCIVREE. Monitor patients for new onset or worsening of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior. Consider discontinuing IMCIVREE if patients experience suicidal thoughts or behaviors or if clinically significant or persistent depression symptoms occur.

Question 17

Can IMCIVREE be used with antidepressants?

Accepted Answer

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

Question 18

Can IMCIVREE cause prolonged erections?

Accepted Answer

Spontaneous penile erections in males (24%) occurred in clinical trials with IMCIVREE. Inform patients that these events may occur and instruct patients who have an erection lasting longer than 4 hours to seek emergency medical attention.

Question 19

What sexual disturbances were reported in females in the clinical trials?

Accepted Answer

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.

Question 20

What should a patient do if they think they are or may become pregnant?

Accepted Answer

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

Question 21

Can patients take IMCIVREE while breastfeeding? Does IMCIVREE enter the breast milk?

Accepted Answer

There is no information on the presence of IMCIVREE or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Treatment with IMCIVREE is not recommended 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.

Question 22

My patient missed a dose. Does he/she need to retitrate their dose?

Accepted Answer

If a dose is missed, the once-daily regimen should be resumed as prescribed with the next scheduled dose.

Question 23

What is the mechanism of action?

Accepted Answer

IMCIVREE 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. Based on nonclinical evidence, IMCIVREE may re-establish MC4 receptor pathway activity to reduce food intake and promote weight loss through decreased caloric intake and increased energy expenditure in patients with obesity due to POMC, PCSK1, or LEPR deficiency, or BBS associated with insufficient activation of the MC4 receptor. 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.

Question 24

Have the pivotal studies on IMCIVREE been published?

Accepted Answer

Yes. The results of these studies have been published in The Lancet Diabetes & Endocrinology.

Question 25

How were the safety and effectiveness of IMCIVREE evaluated?

Accepted Answer

The safety and efficacy of IMCIVREE for the treatment of POMC, PCSK1, or LEPR deficiency obesity were established in 2 identically designed, 1-year, open-label studies, each with an 8-week, double-blind withdrawal period.

Question 26

Were the patients who did not achieve at least a 5-kg weight loss (or at least 5% weight loss if baseline body weight was <100 kg) at the end of the open-label treatment period included in any analyses? If so, which ones?

Accepted Answer

Yes. These patients were included in the primary endpoint analysis and safety analyses.

Question 27

Did patients regain weight after stopping IMCIVREE?

Accepted Answer

Yes. When treatment with IMCIVREE was withdrawn in patients who had lost weight 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. Reinitiation of treatment with IMCIVREE resulted in subsequent weight loss.

Question 28

How do I prescribe IMCIVREE for my patient(s)?

Accepted Answer

Rhythm’s companion diagnostic device (or CDx) is approved by the FDA and is used to identify people who are appropriate for treatment with IMCIVREE based on a genetic confirmation of POMC, PCSK1, or LEPR deficiency.
