IMCIVREE is indicated for the treatment of obesity and the control of hunger associated with genetically confirmed loss-of-function biallelic pro-opiomelanocortin (POMC), including PCSK1, deficiency or biallelic leptin receptor (LEPR) deficiency in adults and children 6 years of age and above.
IMCIVREE should be prescribed and supervised by a physician with expertise in obesity with underlying genetic aetiology.
For adults and children 12 to 17 years of age, the starting dose is a 1 mg once daily subcutaneous injection for 2 weeks. After 2 weeks, if setmelanotide is well-tolerated (see section 4.4), the dose can be increased to a 2 mg once daily subcutaneous injection (Table 1). If dose escalation is not tolerated, patients may maintain administration of the 1 mg once daily dose.
If additional weight loss is desired in adult patients, the dose can be increased to a 2.5 mg once daily subcutaneous injection. If the 2.5 mg once daily dose is well-tolerated, the dose can be increased to 3 mg once daily (Table 1).
In patients aged 12 to 17 years, if weight remains above the 90th percentile with the 2 mg once daily subcutaneous injection and additional weight loss is desired, the dose may be increased to 2.5 mg with a maximum dose of 3 mg once daily (Table 1).
Table 1. Dose titration in adults and paediatric patients more than 12 years of age:
| Week | Daily dose | Volume to be injected |
|---|---|---|
| Weeks 1-2 | 1 mg once daily | 0.1 ml once daily |
| Week 3 and onward | 2 mg once daily | 0.2 ml once daily |
| If clinical response is insufficient and 2 mg dose once daily is well tolerated | 2.5 mg once daily | 0.25 ml once daily |
| If clinical response is insufficient and 2.5 mg dose once daily is well tolerated | 3 mg once daily | 0.3 ml once daily |
For patients aged 6 to <12 years, the starting dose is a 0.5 mg once daily subcutaneous injection for 2 weeks. If tolerated after 2 weeks, the dose can be increased to 1 mg once daily. If dose escalation is not tolerated, paediatric patients may maintain administration of the 0.5 mg once daily dose. If the 1 mg dose is tolerated after 2 weeks, the dose can be increased to 2 mg once daily. If weight remains above the 90th percentile with the 2 mg once daily subcutaneous injection and additional weight loss is desired, the dose may be increased to 2.5 mg once daily (Table 2).
Table 2. Dose titration for paediatric patients from 6 to <12 years of age:
| Week | Daily dose | Volume to be injected |
|---|---|---|
| Patients from 6 to <12 years of age | ||
| Weeks 1-2 | 0.5 mg once daily | 0.05 ml once daily |
| Weeks 3-5 | 1 mg once daily | 0.1 ml once daily |
| Week 6 and onward | 2 mg once daily | 0.2 ml once daily |
| If clinical response is insufficient and 2 mg dose once daily is well tolerated | 2.5 mg once daily | 0.25 ml once daily |
The prescribing physician should periodically assess response to setmelanotide therapy. In growing children, the impact of weight loss on growth and maturation should be evaluated (see section 4.4).
Weight loss and control of hunger associated with setmelanotide can be maintained as long as the therapy is continued uninterrupted. If treatment is discontinued, or if compliance to the dosing regimen is not maintained, symptoms of POMC and LEPR deficiency obesity will return.
If a dose is missed, the once daily regimen should be resumed at the dose prescribed with the next scheduled dose.
For patients with mild renal impairment (see section 5.2), the starting dose is a 0.5 mg once daily subcutaneous injection for 2 weeks. If tolerated after 2 weeks, the dose can be increased to 1 mg once daily. If the 1 mg dose is tolerated after 2 weeks, the dose can be increased to 2 mg once daily.
For patients aged 6 to <12 years with mild renal impairment, the maximum dose is 2 mg once daily.
For patients more than 12 years of age, if additional weight loss is desired, the dose may be increased to 2.5 mg once daily. If the 2.5 mg once daily dose is well-tolerated, the dose can be increased to 3 mg once daily (Table 3). 4 Setmelanotide should not be administered to any patients with moderate or severe renal impairment.
Table 3. Dose titration for patients with mild renal impairment:
| Week | Daily dose | Volume to be injected |
|---|---|---|
| All patients with mild renal impairment | ||
| Weeks 1-2 | 0.5 mg once daily | 0.05 ml once daily |
| Weeks 3-5 | 1 mg once daily | 0.1 ml once daily |
| Week 6 and onward | 2 mg once daily | 0.2 ml once daily |
| Patients more than 12 years of age with mild renal impairment | ||
| If clinical response is insufficient, and 2 mg dose once daily is well tolerated | 2.5 mg once daily | 0.25 ml once daily |
| If clinical response is insufficient and 2.5 mg dose once daily is well tolerated | 3 mg once daily | 0.3 ml once daily |
Setmelanotide has not been studied in patients with hepatic impairment. Setmelanotide should not be administered to patients with hepatic impairment.
The safety and efficacy of setmelanotide in children less than 6 years of age has not yet been established. No data are available.
For subcutaneous use.
Setmelanotide should be injected once daily, at the beginning of the day (to maximise hunger reduction during awake period), without regard to the timing of meals.
Setmelanotide should be injected subcutaneously in the abdomen, alternating the abdominal area each day.
Prior to initiation of treatment, patients should be trained by their healthcare professional on proper injection technique, to reduce the risk of administration errors such as needle sticks and incomplete dosing. Refer to the patient leaflet for complete administration instructions with illustrations.
See section 6.6 for instructions on handling IMCIVREE.
The symptoms of setmelanotide overdose may include nausea and penile erection. In the event of overdose, appropriate supportive treatment should be initiated according to the patient’s clinical signs and symptoms. In cases of overdose, blood pressure and heart rate should be monitored regularly over 48 hours or as long as clinically relevant.
