4.CLINICAL PARTICULARS

4.1Therapeutic indications

Empliciti is indicated in combination with lenalidomide and dexamethasone for the treatment of multiple myeloma in adult patients who have received at least one prior therapy (see sections 4.2 and 5.1).

4.2Posology and method of administration

Elotuzumab therapy should be initiated and supervised by physicians experienced in the treatment of multiple myeloma.

Premedication for prevention of infusion reaction

Patients must be administered with the following premedications 45-90 minutes prior to Empliciti infusion (see section 4.4):

Dexamethasone 8 mg intravenous

H1 blocker: diphenhydramine (25-50 mg orally or intravenous) or equivalent H1 blocker. H2 blocker: ranitidine (50 mg intravenous or 150 mg orally) or equivalent H2 blocker. Paracetamol (650-1000 mg orally).

Management of infusion reaction

If a ≥ Grade 2 infusion reaction occurs during Empliciti administration, the infusion must be interrupted. Upon resolution to ≤ Grade 1, Empliciti should be restarted at 0.5 mL/min and may be gradually increased at a rate of 0.5 mL/min every 30 minutes as tolerated to the rate at which the infusion reaction occurred. If there is no recurrence of the infusion reaction, the escalation can be resumed (see Table 2).

In patients who experience an infusion reaction, vital signs should be monitored every 30 minutes for 2 hours after the end of the Empliciti infusion. If the infusion reaction recurs, the Empliciti infusion must be stopped and not restarted on that day (see section 4.4). Very severe infusion reactions

(≥ Grade 3) may require permanent discontinuation of Empliciti therapy and emergency treatment.

Posology for administration with lenalidomide and dexamethasone

The dosing schedule is presented in Table 1.

Treatment should continue until disease progression or unacceptable toxicity.

The recommended dose of Empliciti is 10 mg/kg administered intravenously every week (28-day cycle), on days 1, 8, 15, and 22 for the first two cycles and every 2 weeks thereafter on days 1 and 15.

The recommended dose of lenalidomide is 25 mg orally once daily on days 1-21 of repeated 28-day cycles, and at least 2 hours after Empliciti infusion when administered on the same day.

The administration of dexamethasone is as follows:

On days that Empliciti is administered, dexamethasone should be given as 28 mg orally once daily between 3 and 24 hours before Empliciti plus 8 mg intravenously between 45 and

90 minutes before Empliciti on days 1, 8, 15, and 22 of repeated 28-day cycles.

On days that Empliciti is not administered but a dose of dexamethasone is scheduled (Days 8 and 22 of cycle 3 and all subsequent cycles), dexamethasone should be given 40 mg orally.

Dose delay, interruption, or discontinuation

If the dose of one medicine in the regimen is delayed, interrupted, or discontinued, the treatment with the other medicinal products may continue as scheduled. However, if oral or intravenous

dexamethasone is delayed or discontinued, the administration of Empliciti should be based on clinical judgment (e.g. risk of hypersensitivity) (see section 4.4).

Special populations

Paediatric population

There is no relevant use of Empliciti in the paediatric population for the indication of multiple myeloma.

Elderly

No dose adjustment is required for elotuzumab in patients over 65 years of age (see section 5.2). Data on the efficacy and safety of elotuzumab in patients ≥ 85 years of age are very limited.

Renal impairment

No dose adjustment of Empliciti is required for patients with mild (CrCl = 60 - 89 mL/min), moderate (CrCl = 30 - 59 mL/min), severe (CrCl < 30 mL/min) renal impairment or end stage renal disease requiring dialysis (see section 5.2).

Hepatic impairment

No dose adjustment for Empliciti is required for patients with mild hepatic impairment (total bilirubin [TB] ≤ to the upper limit of normal [ULN] and AST > ULN or TB < 1 to 1.5 × ULN and any AST). Empliciti has not been studied in patients with moderate (TB > 1.5 to 3 × ULN and any AST) or severe (TB > 3 × ULN and any AST) hepatic impairment (see section 5.2).

Method of administration

Empliciti is for intravenous use only.

The administration of the reconstituted and diluted solution must be initiated at an infusion rate of

0.5 mL/min. If the infusion is well tolerated the infusion rate may be increased in a stepwise fashion as described in Table 2. The maximum infusion rate should not exceed 5 mL/min.

4.3Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

The Summary of Product Characteristics for all medicinal products used in combination with Empliciti must be consulted before starting therapy.

4.4Special warnings and precautions for use

Infusion reaction

Infusion reactions have been reported in patients receiving elotuzumab (see section 4.8).

Premedication consisting of dexamethasone, H1 blocker, H2 blocker, and paracetamol must be administered prior to Empliciti infusion (see section 4.2 Premedication). The rate of infusion reactions was much higher in patients who were not premedicated.

If any of the symptoms of infusion reaction reach Grade ≥ 2, Empliciti infusion must be interrupted and appropriate medical and supportive measures instituted. Vital signs should be monitored every 30 minutes for 2 hours after the end of the Empliciti infusion. Once the reaction has resolved (symptoms ≤ Grade 1), Empliciti can be restarted at the initial infusion rate of 0.5 mL/min. If symptoms do not recur, the infusion rate may be gradually escalated every 30 minutes to a maximum of 5 mL/min (see section 4.2 Method of administration).

Very severe infusion reactions may require permanent discontinuation of Empliciti therapy and emergency treatment. Patients with mild or moderate infusion reactions may receive Empliciti with a reduced infusion rate and close monitoring (see section 4.2 Method of administration).

Conditions for use of medicinal products used with Empliciti

Empliciti is used in combination with other medicinal products; therefore, the conditions for use applicable to those medicinal products also apply to the combination therapy. The Summary of Product Characteristics for all medicinal products used in combination with Empliciti must be consulted before starting therapy.

Infections

In clinical trials of patients with multiple myeloma, the incidence of all infections, including pneumonia, were higher in patients treated with Empliciti (see section 4.8). Patients should be monitored and infections should be managed with standard treatment.

Second primary malignancies (SPMs)

In a clinical trial of patients with multiple myeloma that compared Empliciti combined with lenalidomide and dexamethasone treatment to lenalidomide and dexamethasone treatment (Study 1), the incidence of SPMs, and specifically of solid tumours and non-melanoma skin cancer, was higher in patient treated with Empliciti (see section 4.8). SPMs are known to be associated with lenalidomide exposure, which was extended in patients treated with Empliciti combined with lenalidomide and dexamethasone vs. lenalidomide and dexamethasone. The rate of haematologic malignancies was the same between the two treatment arms. Patients should be monitored for the development of SPMs.

4.5Interaction with other medicinal products and other forms of interaction

Pharmacokinetic interaction studies have not been conducted. Empliciti, as a humanised monoclonal antibody, is not expected to be metabolised by cytochrome P450 (CYP) enzymes or other drug metabolising enzymes, inhibition or induction of these enzymes by co-administered medicinal products is not anticipated to affect the pharmacokinetics of Empliciti.

Empliciti may be detected in the serum protein electrophoresis (SPEP) and serum immunofixation assays of myeloma patients and could interfere with correct response classification. The presence of elotuzumab in patient's serum may cause a small peak in the early gamma region on SPEP that is IgGƙ on serum immunofixation. This interference can impact the determination of complete response and possibly relapse from complete response in patients with IgG kappa myeloma protein.

In case of detection of additional peaks on serum immunofixation, the possibility of a biclonal gammopathy should be excluded.

The Summary of Product Characteristics for all medicinal products used in combination with Empliciti must be consulted before starting therapy.

4.6Fertility, pregnancy and lactation

Woman of childbearing potential/Contraception in the males and females

Empliciti should not be used in women of childbearing potential, unless the clinical condition of the woman requires treatment with elotuzumab. Women of childbearing potential should use effective contraception.

Male patients must use effective contraception measures during and for 180 days following treatment if their partner is pregnant or of childbearing potential and not using effective contraception.

Pregnancy

There is no human experience with elotuzumab during pregnancy. Elotuzumab will be given in combination with lenalidomide, which is contraindicated during pregnancy. No animal data are present regarding the effect on reproductive toxicity because of the lack of an adequate animal model. Empliciti should not be used during pregnancy unless the clinical condition of the woman requires treatment with elotuzumab.

The Summary of Product Characteristics for all medicinal products used in combination with Empliciti must be consulted before starting therapy. When Empliciti is used with lenalidomide there is a risk of foetal harm, including severe life-threatening human birth defects associated with these agents and the need to follow requirements regarding pregnancy avoidance, including testing and contraception. Lenalidomide is present in the blood and sperm of patients receiving the medicine. Refer to the Summary of Product Characteristics for requirements regarding contraception due to presence and transmission in sperm and for additional detail. Patients receiving Empliciti in combination with lenalidomide should adhere to the pregnancy prevention programme of lenalidomide.

Breast-feeding

Elotuzumab is not expected to be excreted into human milk. Elotuzumab will be given in combination with lenalidomide and breast-feeding should be stopped because of the use of lenalidomide.

Fertility

Studies to evaluate the effect of elotuzumab on fertility have not been performed. Thus, the effect of elotuzumab on male and female fertility is unknown.

4.7Effects on ability to drive and use machines

On the basis of reported adverse reactions, Empliciti is not expected to influence the ability to drive or use machines. Patients experiencing infusion reactions should be advised not to drive and use machines until symptoms abate.

4.8Undesirable effects

Summary of safety profile

The safety data of elotuzumab have been assessed from a total of 554 patients with multiple myeloma treated with elotuzumab in combination with lenalidomide and dexamethasone (451 patients) or bortezomib and dexamethasone (103 patients) pooled across 6 clinical trials. The majority of adverse reactions were mild to moderate (Grade 1 or 2).

The most serious adverse reaction that may occur during elotuzumab treatment is pneumonia.

The most common adverse reactions (occurring in > 10% of patients) with elotuzumab treatment were infusion related reactions, diarrhoea, herpes zoster, nasopharyngitis, cough, pneumonia, upper respiratory tract infection, lymphopenia and weight decreased.

Tabulated list of adverse reactions

Adverse reactions reported in 554 patients with multiple myeloma who were treated with elotuzumab in 6 clinical trials are presented in Table 3.

These reactions are presented by system organ class and by frequency. Frequencies are defined as: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); and not known (cannot be estimated from available data).

Description of selected adverse reactions

Infusion reactions

In a clinical trial of patients with multiple myeloma (Study 1), infusion reactions were reported in approximately 10% of premedicated patients treated with Empliciti combined with lenalidomide and

dexamethasone (N = 318) (see section 4.4). The rate of mild to moderate infusion reactions was > 50% in patients who were not premedicated. All reports of infusion reaction were ≤ Grade 3. Grade 3 infusion reactions occurred in 1% of patients. The most common symptoms of an infusion reaction included fever, chills, and hypertension. Five percent (5%) of patients required interruption of the administration of Empliciti for a median of 25 minutes due to infusion reaction, and 1% of patients discontinued due to infusion reactions. Of the patients who experienced an infusion reaction, 70% (23/33) had the reaction during the first dose.

Infections

The incidence of infections, including pneumonia, was higher with Empliciti treatment than with control (see section 4.4). In a clinical trial of patients with multiple myeloma (Study 1), infections were reported in 81.4% of patients in the Empliciti combined with lenalidomide and dexamethasone arm (N = 318) and 74.4% in lenalidomide and dexamethasone arm (N = 317). Grade 3-4 infections were noted in 28% and 24.3% of Empliciti combined with lenalidomide and dexamethasone and lenalidomide and dexamethasone treated patients, respectively. Fatal infections were infrequent and were reported in 2.5% of Empliciti combined with lenalidomide and dexamethasone and 2.2% of lenalidomide and dexamethasone treated patients. The incidence of pneumonia was higher in the Empliciti combined with lenalidomide and dexamethasone arm compared to lenalidomide and dexamethasone arm reported at 15.1% vs. 11.7% with a fatal outcome at 0.6% vs. 0%, respectively.

Second Primary Malignancies

The incidence of SPMs was higher with Empliciti treatment than with control (see section 4.4). In a clinical trial of patients with multiple myeloma (Study 1), invasive SPMs have been observed in 6.9% of patients treated with Empliciti combined with lenalidomide and dexamethasone (N = 318) and 4.1% of patients treated with lenalidomide and dexamethasone (N = 317). Second Primary Malignancies are known to be associated with lenalidomide exposure which was extended in patients treated with Empliciti combined with lenalidomide and dexamethasone vs. lenalidomide and dexamethasone. The rate of haematologic malignancies were the same between the two treatment arms (1.6%). Solid tumours were reported in 2.5% and 1.9% of Empliciti combined with lenalidomide and dexamethasone and lenalidomide and dexamethasone treated patients, respectively. Non-melanoma skin cancer was reported in 3.1% and 1.6% of patients treated with Empliciti combined with lenalidomide and dexamethasone and lenalidomide and dexamethasone, respectively.

Deep vein thrombosis

In a clinical trial of patients with multiple myeloma (Study 1), deep vein thromboses were reported in 7.2% of patients treated with Empliciti combined with lenalidomide and dexamethasone (N = 318) and 3.8% of patients treated with lenalidomide and dexamethasone (N = 317). Among, patients treated with aspirin, deep vein thromboses were reported in 4.1% of patients treated with Empliciti combined with lenalidomide and dexamethasone (E-Ld) and 1.4% of patients treated with lenalidomide and dexamethasone (Ld). The rates of deep vein thromboses observed between treatment arms were similar for patients given prophylaxis with low molecular weight heparin (2.2% in both treatment arms), and for patients given vitamin K antagonists the rates were 0% for patients treated with E-Ld and 6.7% for patients treated with Ld.

Immunogenicity

As with all therapeutic proteins, there is a potential for immunogenicity to Empliciti.

Of 390 patients across four clinical studies who were treated with Empliciti and evaluable for the presence of anti-product antibodies, 72 patients (18.5%) tested positive for treatment-emergent anti-product antibodies by an electrochemiluminescent (ECL) assay. Neutralizing antibodies were detected in 19 of 299 patients in Study 1. In the majority of patients, immunogenicity occurred early in treatment and was transient resolving by 2 to 4 months. There was no clear causal evidence of altered pharmacokinetic, efficacy, or toxicity profiles with anti-product antibody development based on the population pharmacokinetic and exposure-response analyses.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare

professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.

4.9Overdose

One patient was reported to be overdosed with 23.3 mg/kg of elotuzumab in combination with lenalidomide and dexamethasone. The patient had no symptoms, did not require any treatment for the overdose, and was able to continue on elotuzumab therapy.

In clinical studies, approximately 78 patients were evaluated with elotuzumab at 20 mg/kg without apparent toxic effects.

In case of overdose, patients should be closely monitored for signs or symptoms of adverse reactions, and appropriate symptomatic treatment instituted.

5.PHARMACOLOGICAL PROPERTIES

5.1Pharmacodynamic properties

Pharmacotherapeutic group: Antineoplastic agents, monoclonal antibodies. ATC code: L01XC23.

Mechanism of action

Elotuzumab is an immunostimulatory humanised, IgG1 monoclonal antibody that specifically targets the SLAMF7 (signaling lymphocyte activation molecule family member 7) protein. SLAMF7 is highly expressed on multiple myeloma cells independent of cytogenetic abnormalities. SLAMF7 is also expressed on natural killer cells, normal plasma cells, and other immune cells including some

T cell subsets, monocytes, B cells, and pDCs (plasmacytoid dendritic cells), but is not detected on normal solid tissues or haematopoietic stem cells.

Elotuzumab directly activates natural killer cells through both the SLAMF7 pathway and Fc receptors enhancing anti-myeloma activity in vitro. Elotuzumab also targets SLAMF7 on myeloma cells and facilitates the interaction with natural killer cells to mediate the killing of myeloma cells through antibody-dependent cellular cytotoxicity (ADCC). In nonclinical models, elotuzumab has demonstrated synergistic activity when combined with lenalidomide or bortezomib.

Clinical efficacy and safety

Two randomised, open-label studies were conducted to evaluate the efficacy and safety of Empliciti (elotuzumab) in adult patients with multiple myeloma who have received one or more prior therapies. Study 1 provided the pivotal data for the indication for Empliciti in combination with lenalidomide and dexamethasone.

Study 1

A randomised, open-label study was conducted to evaluate the efficacy and safety of Empliciti in combination with lenalidomide and dexamethasone in patients with multiple myeloma who have received one to three prior therapies. All patients had documented progression following their most recent therapy. Patients who were refractory to lenalidomide were excluded and 6% of patients had prior lenalidomide treatment. Patients had to recover after transplant for a minimum of 12 weeks from autologous stem cell transplant (SCT), and 16 weeks from allogeneic SCT. Patients with cardiac amyloidosis or plasma cell leukemia were excluded from this study.

Eligible patients were randomised in a 1:1 ratio to receive either Empliciti in combination with lenalidomide and dexamethasone or lenalidomide and dexamethasone. Treatment was administered in 4-week cycles until disease progression or unacceptable toxicity. Elotuzumab 10 mg/kg was administered intravenously each week for the first 2 cycles and every 2 weeks thereafter. Prior to Empliciti infusion, dexamethasone was administered as a divided dose: an oral dose of 28 mg and an

intravenous dose of 8 mg. In the control group and on weeks without Empliciti, dexamethasone 40 mg was administered as a single oral dose weekly. Lenalidomide 25 mg was taken orally once daily for the first 3 weeks of each cycle. Assessment of tumour response was conducted every 4 weeks.

A total of 646 patients were randomised to receive treatment: 321 to Empliciti in combination with lenalidomide and dexamethasone and 325 to lenalidomide and dexamethasone.

Demographics and baseline characteristics were well balanced between treatment arms. The median age was 66 years (range 37 to 91); 57% of patients were older than 65 years; 60% of patients were male; Whites comprised 84% of the study population, Asians 10%, and blacks 4%. The International Staging System (ISS) Stage was I in 43%, II in 32% and III in 21% of patients. The high risk cytogenetic categories of del17p and t(4;14) were present in 32% and 9% of patients, respectively. The median number of prior therapies was 2. Thirty-five percent (35%) of patients were refractory (progression during or within 60 days of last therapy) and 65% were relapsed (progression after

60 days of last therapy). Prior therapies included: stem cell transplant (55%), bortezomib (70%) melphalan (65%), thalidomide (48%), and lenalidomide (6%).

The primary endpoints of this study, progression-free survival (PFS), as assessed by hazard ratio, and overall response rate (ORR) were determined based on assessments made by a blinded Independent Review Committee. Efficacy results are presented in Table 5 and Figure 1. The median number of treatment cycles was 19 for the Empliciti arm and 14 for the comparator arm.

Paediatric population

The European Medicines Agency has waived the obligation to submit the results of studies in all subsets of the paediatric population in treatment of multiple myeloma (see section 4.2 for information on paediatric use).

5.2Pharmacokinetic properties

The pharmacokinetics (PK) of elotuzumab was studied in patients with multiple myeloma. Elotuzumab exhibits nonlinear PK with decrease in clearance with increase in dose from 0.5-20 mg/kg.

Absorption

Elotuzumab is dosed via intravenous route and therefore is immediately and completely bioavailable.

Distribution

The geometric mean volume of distribution of elotuzumab at 10 mg/kg (in combination with lenalidomide and dexamethasone) at steady state is 6.02 L (CV: 22.1%).

Biotransformation

The metabolic pathway of elotuzumab has not been characterized. As an IgG monoclonal antibody, elotuzumab is expected to be degraded into small peptides and amino acids via catabolic pathways.

Elimination

The geometric mean total clearance of elotuzumab at 10 mg/kg (in combination with lenalidomide and dexamethasone) at steady state is 0.194 L/day (CV: 62.9%). Upon discontinuation of elotuzumab in combination with lenalidomide and dexamethasone, concentrations of elotuzumab will decrease to approximately 3% (approximately 97% washout as estimated by 5 half-lives) of the population predicted steady-state maximal serum concentration by 3 months.

Special populations

Based on a population PK analysis using data from 375 patients, the clearance of elotuzumab increased with increasing body weight supporting a weight-based dose. The population PK analysis suggested that the following factors had no clinically important effect on the clearance of elotuzumab: age (37 to 88 years), gender, race, baseline LDH, albumin, renal impairment, and mild hepatic impairment.

Renal impairment

An open-label study evaluated the pharmacokinetics of elotuzumab in combination with lenalidomide and dexamethasone in patients with multiple myeloma with varying degrees of renal impairment (classified using the CrCl values). The effect of renal impairment on the pharmacokinetics of elotuzumab was evaluated in patients with normal renal function (CrCl > 90 mL/min; N = 8), severe renal impairment not requiring dialysis (CrCl <30 mL/min; N = 9), or end-stage renal disease requiring dialysis (CrCl < 30 mL/min; N = 9). No clinically important differences in the pharmacokinetics of elotuzumab were found between patients with severe renal impairment (with and without dialysis) and patients with normal renal function (see section 4.2).

Hepatic impairment

Empliciti is an IgG1 monoclonal antibody, which is principally cleared by catabolism. Thus, hepatic functional impairment is not likely to alter its clearance. The effect of hepatic impairment on the clearance of Empliciti was evaluated by population PK analyses in patients with mild hepatic impairment (total bilirubin [TB] ≤ the upper limit of normal [ULN] and AST > ULN or

TB < 1 to 1.5 × ULN and any AST; N = 33). No clinically important differences in the clearance of Empliciti were found between patients with mild hepatic impairment and patients with normal hepatic function. Elotuzumab has not been studied in patients with moderate (TB > 1.5 to 3 × ULN and any AST) or severe hepatic impairment (TB > 3 × ULN and any AST) (see section 4.2).

5.3Preclinical safety data

Elotuzumab only recognizes human SLAMF7 protein. Because elotuzumab does not recognize non-human forms of SLAMF7 protein, in vivo safety data from animal studies are irrelevant. In the same line, no carcinogenicity data are available for elotuzumab in animals, nor were fertility and embryo-foetal toxicity studies performed. Non-clinical safety information primarily consists of limited in vitro human cell/tissue studies where no safety findings were identified.

6.2Incompatibilities

In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products.

6.3Shelf life

Unopened vial 3 years.

After reconstitution and dilution

The reconstituted solution should be transferred from the vial into the infusion bag immediately.

Chemical and physical in use stability of the reconstituted and diluted solution has been demonstrated for 24 hours at 2°C - 8°C and protected from light.

From a microbiological point of view, the solution for infusion should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2°C - 8°C protected from light. Do not freeze the reconstituted or diluted solution. The solution for infusion may be stored for a maximum of 8 hours of the total 24 hours at 20°C − 25°C and room light. This 8-hour period should be inclusive of the product administration period.

6.4Special precautions for storage

Store in a refrigerator (2°C - 8°C).

Do not freeze.

Store in the original package in order to protect from light.

For storage conditions after reconstitution or dilution of the medicinal product, see section 6.3.

6.5Nature and contents of container

20 ml Type I glass vial, closed with a grey butyl stopper and sealed with aluminium crimp seal with a polypropylene flip off button, containing either 300 mg or 400 mg elotuzumab. The flip-off seal button colour is ivory for the 300 mg presentation and blue for the 400 mg presentation.

Pack size of 1 vial.

6.6Special precautions for disposal and other handling

Calculating the dose

Calculate the dose (mg) and determine the number of vials needed for the 10 mg/kg dose based on patient weight. More than one vial of Empliciti may be needed to give the total dose for the patient.

The total elotuzumab dose in mg = the patient’s weight in kg x 10.

Preparing the infusion

Aseptically reconstitute each Empliciti vial with a syringe of adequate size and an 18 gauge or smaller needle as shown in Table 7. A slight back pressure may be experienced during administration of the water for injections, which is considered normal.

Hold the vial upright and swirl the solution by rotating the vial to dissolve the lyophilised cake. Then invert the vial a few times in order to dissolve any powder that may be present on top of the vial or the stopper. Avoid vigorous agitation, DO NOT SHAKE. The lyophilised powder should dissolve in less than 10 minutes.

After the remaining solids are completely dissolved, allow the reconstituted solution to stand for 5 to 10 minutes. The reconstituted solution is colourless to slightly yellow, and clear to very

opalescent. Empliciti should be inspected visually for particulate matter and discolouration prior to administration. Discard the solution if any particulate matter or discolouration is observed.

Once the reconstitution is completed, withdraw the necessary volume for the calculated dose from each vial, up to a maximum of 16 mL from 400 mg vial and 12 mL from 300 mg vial. Dilute the reconstituted solution with 230 mL of either sodium chloride

9 mg/mL (0.9%) solution for injection or 5% glucose injection, into an infusion bag made of polyvinyl chloride or polyolefin. The volume of sodium chloride 9 mg/mL (0.9%) solution for injection or 5% glucose injection should be adjusted so as not to exceed 5 mL/kg of patient weight at any given dose of Empliciti.

Administration

The entire Empliciti infusion should be administered with an infusion set and a sterile, non-pyrogenic, low-protein-binding filter (with a pore size of 0.2-1.2 µm) using an automated infusion pump.

Empliciti infusion is compatible with:

PVC and polyolefin containers

PVC infusion sets

polyethersulfone and nylon in-line filters with pore sizes of 0.2 μm to 1.2 μm.

Empliciti should be initiated at an infusion rate of 0.5 mL/min. If well tolerated, the infusion rate may be increased stepwise as described in Table 2 (see section 4.2 Method of administration). The maximum infusion rate should not exceed 5 mL/min.

The Empliciti infusion solution should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2°C − 8°C protected from light. Do not freeze the reconstituted or diluted solution. The solution for infusion may be stored for a maximum of 8 hours of the total 24 hours at

20°C − 25°C and room light. This 8-hour period should be inclusive of the product administration period.

Disposal

Do not store any unused portion of the infusion solution for reuse. Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
