4.CLINICAL PARTICULARS

4.1Therapeutic indications

Ceplene maintenance therapy is indicated for adult patients with acute myeloid leukaemia (AML) in first remission concomitantly treated with interleukin-2 (IL-2). The efficacy of Ceplene has not been fully demonstrated in patients older than age 60.

4.2Posology and method of administration

Ceplene maintenance therapy should be administered following completion of consolidation therapy in patients concomitantly treated with IL-2 under the supervision of a physician experienced in the management of acute myeloid leukaemia.

Posology

For dosing instructions for Ceplene in combination with IL-2, see posology below.

Interleukin-2 (IL-2)

IL-2 is administered twice daily as a subcutaneous injection 1 to 3 minutes prior to the administration of Ceplene; each dose of IL-2 is 16 400 IU/kg (1 µg/kg).

Interleukin-2 (IL-2) is commercially available as a recombinant IL-2; aldesleukin. The dispensing and storage directions below are specific to aldesleukin.

Dispensing instructions for IL-2 (aldesleukin)

IL-2 (aldesleukin) should be aseptically reconstituted, diluted and dispensed in capped polypropylene tuberculin syringes by the pharmacy based on the individual patient’s weight (see administration chart for aldesleukin below) at the recommended dose of 16 400 IU/kg (1 µg/kg). Up to two weeks supply of pre-filled capped tuberculin syringes may be provided to patients for home administration, with instructions that the syringes be stored under refrigeration at 2°C – 8°C prior to administration.

Studies have shown chemical stability and sterility of diluted aldesleukin (dispensed in capped polypropylene tuberculin syringes) for up to three weeks when prepared in a controlled aseptic environment and stored under refrigeration at 2°C – 8°C.

NOTE: Dispensing of aldesleukin must be carried out under controlled aseptic conditions.

Dispensing of dilute IL-2 (Aldesleukin) for each patient

The diluted IL-2 (aldesleukin) is aseptically drawn up into sterile polypropylene tuberculin syringes and capped for each patient at 1 µg/kg dose, with a minimum standard dosage volume of 0.25 mL (50 µg) and a maximum dose of 0.5 mL (100 µg). Dosing volumes based on patient weight are provided in Table 1 below. This table also provides the volume required if a 20% dose reduction is prescribed.

Ceplene

0.5 mL solution is sufficient for a single dose (see section 6.6).

Ceplene is administered 1 to 3 minutes after each injection of IL-2. Each 0.5 mL Ceplene dose is injected slowly, over 5-15 minutes.

Treatment cycles

Ceplene and IL-2 are administered for 10 treatment cycles: each cycle consists of a treatment period of 21 days (3 weeks) followed by a three-week or six-week treatment-free period.

For cycles 1-3, each cycle consists of 3 weeks of treatment, followed by a 3-week treatment free period. For cycles 4-10, each cycle consists of 3 weeks of treatment, followed by a 6-week treatment- free period.

The recommended dosing regimen is presented in Tables 2 and 3.

Dose modification

Patients should be monitored for the expected symptomatic adverse reactions and laboratory changes associated with this treatment. Doses of Ceplene and IL-2 should be modified as necessary based on individual patient tolerance to treatment. It is recommended that dose modifications be addressed early in treatment. The dose reductions can be temporary or permanent.

Should Ceplene related toxicities occur (such as hypotension, headache), the injection time can be increased from 5 minutes to a maximum duration of 15 minutes.

For patients experiencing grade 1 toxicity events

No altered dose recommendations with the exception of grade 1 neurologic toxicity and grade 1 generalised toxic dermatitis. For the dose recommendations for these grade 1 toxicity events refer to the relevant sections below:

For patients experiencing grade 1-4 neurologic toxicity

-for grade 1 to 3 toxicity, treatment should be discontinued until grade 0 toxicity event has been achieved. Treatment should then be resumed at a 20% dose reduction for both Ceplene and IL-2.

-for grade 4 toxicity, discontinuation of treatment should be considered.

For patients experiencing grade 1-4 generalised toxic dermatitis

-for grade 1 toxicity, the treatment should be delayed for 48 hours or until all symptoms have been resolved. Treatment should then be resumed using the full dose of Ceplene, but reducing the IL-2 dose by 20%.

-for grade 2 toxicity, the IL-2 dose should be reduced 50% and only increased to full dose if the symptoms do not reappear. Ceplene and IL-2 doses should be separated by 60 minutes, which should be maintained throughout treatment.

-for grade 3 and 4 toxicity, treatment should be discontinued and not resumed until events

have been resolved. Treatment should only be resumed after consideration of risk – benefit to the patient.

For patients experiencing grade 2 (including cardiac function, renal, hepatic) toxicity

-treatment should be discontinued until the event has returned to grade 1

-the time of injection of the dose of Ceplene should be extended to a maximum of 15 minutes.

-for cardiac, hepatic or renal toxicities the dose should be reduced by 20% for both Ceplene and IL-2.

For patients experiencing grade 3 and 4 (including hypotension, arrhythmia) toxicities

-treatment should be discontinued until the event is resolved. A maximum delay of one treatment cycle can be considered for the resolution of grade 3 and 4 events.

For persistent hypotension, headache, arrhythmia, cardiac, hepatic and renal toxicities

-the time of injection of the dose of Ceplene should be extended to a maximum of 15 minutes.

-the dose amount of both Ceplene and IL-2 should be reduced by 20%.

Fever

- IL-2 can be discontinued for 24 hours and then restarted at a 20% dose reduction level.

Abnormal WBC counts

- the dose of IL-2 can be reduced by 20% for the remaining duration of the treatment course and if abnormal WBC counts re-occur during the following cycle a permanent IL-2 reduction is recommended.

Localised toxic dermatitis

-treatment should be discontinued until symptoms resolved. Treatment can be resumed by administering Ceplene at the full dose and IL-2 at 50%.

Special populations

Renal impairment

Patients with renal impairment may be more sensitive to the blood pressure lowering effects of Ceplene. Although the degree of renal impairment has no demonstrable effect on the pharmacokinetic disposition of Ceplene, caution is warranted when Ceplene is administered to patients with severe renal impairment. However, no Ceplene dose reduction is normally required in renally impaired patients.

Hepatic impairment

Ceplene should be used with caution in patients with moderate to severe hepatic impairment (see section 5.2). Plasma Ceplene levels are higher in patients with moderate and severe liver impairment, and these patient groups tend to experience more tachycardia and lower blood pressure after Ceplene dosing than do patients with normal or mildly affected liver function. Plasma drug levels were not predictive of adverse effects, however, and effects did not correlate closely with drug exposure. Dose reduction of Ceplene is normally not required in hepatically impaired patients, but caution should be used in these patients.

Paediatric population

The safety and efficacy of Ceplene in children below 18 years of age have not yet been established. No data are available.

Method of administration

Ceplene is for subcutaneous use only.

One to 3 minutes after the subcutaneous administration of IL-2 has been completed, Ceplene should be administered by slow subcutaneous injection at a rate not to exceed 0.1 mL (0.1 mg histamine dihydrochloride) per minute. The usual time for administering a 0.5 mL Ceplene dose is 5 minutes. To reduce potential adverse reactions, the administration time may be lengthened to a maximum of 15 minutes, see below. Ceplene can be administered via an ambulatory infusion syringe pump or by controlled manual subcutaneous injection by syringe with a timer.

The first dose of Ceplene and IL-2 on day 1 of the initiation of the first cycle of treatment should be administered in the clinic under direct supervision by a physician. Patient monitoring on day 1 should include vital signs, including pulse, blood pressure and respiratory rate. If the patient experiences a significant change in vital signs, the physician should evaluate the status of the patient and continue to monitor vital signs; these patients should be monitored during subsequent treatments.

Subsequent injections of Ceplene may be self-administered at home by a patient who demonstrates a good understanding of necessary precautions and who has demonstrated adequate injection skills. Injections should be preferably administered in a supervised setting in the presence of an adult family member, friend, or other care provider who is capable of responding appropriately should signs or symptoms of hypotension occur.

The preferred injection areas are the thighs and the abdomen. Ceplene should not be injected into the same anatomic region as IL-2.

The twice daily dosing of IL-2 and Ceplene should be separated by a minimum of 6 hours. Patients should remain at rest for 20 minutes after injection of Ceplene.

For instructions on reconstitution and dilution of Interleukin-2 (aldesleukin) before administration, see section 6.6.

4.3Contraindications

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

Patients with significantly compromised cardiac function, e.g., NYHA Class III/IV.

Patients receiving systemic steroid therapy, clonidine and H2 blocking agents.

Patients who have received an allogenic stem cell transplant.

During pregnancy.

During breast feeding.

4.4Special warnings and special precautions for use

Ceplene should be administered 1 to 3 minutes after IL-2 administration, and not concomitantly. Rapid subcutaneous injection or injection into a vascular space may result in severe hypotension, tachycardia, or syncope.

Treatment with Ceplene in conjunction with IL-2 should be used with caution in patients with poorly compensated cardiac function. Patients with cardiac disease should be evaluated for ventricular ejection fraction and wall function by echocardiography or nuclear medicine stress test and then treated with caution.

Patients should be monitored during treatment for possible clinical complications due to hypotension or hypovolaemia. Ceplene should be administered in the clinic under supervision of the physician on day 1 of the initial treatment cycle. Patient monitoring on day 1 should include vital signs, including pulse, blood pressure and respiratory rate.

Patient monitoring during subsequent treatment days or cycles should be performed as long as the patient continues to experience significant changes in vital signs during administration of Ceplene. If significant hypotension or related symptoms are observed in subsequent treatment cycles, dose reduction should be initiated and if required, administered in hospital until responses to treatment allow for home administration.

Caution should be used for patients with any of the following: symptomatic peripheral arterial disease, past or present peptic or oesophageal ulcer disease with a history of bleeding, clinically significant renal disease and stroke within the last 12 months. Where appropriate, consideration should be made to providing concomitant treatment with a proton pump inhibitor.

Patients with clinically significant infection requiring the use of antibiotics, antifungals, or antivirals, or who have completed prior anti-infectious therapy within 14 days of starting treatment should be treated with caution unless the use of antibiotics and antivirals were for prophylaxis purposes.

Patients with a prior history of autoimmune disease (including systemic lupus, inflammatory bowel disease, psoriasis and rheumatoid arthritis) should be treated with caution.

Monitoring of laboratory test results is recommended including standard haematological and blood chemistry tests.

Patients receiving the following medicinal products should be treated with caution (see section 4.5):

-Beta-blockers or other anti-hypertensive agents.

-H1 blocking agents and neuroleptics (anti-psychotics) with H1 receptor blocking properties.

-Tricyclic anti-depressants that may have H1 and H2 receptor blocking properties.

-Monoamine oxidase inhibitors and anti-malarial and anti-trypanosomal agents.

-Neuromuscular blocking agents, narcotic analgesics, and various contrast media.

4.5Interaction with other medicinal products and other forms of interaction

While posology differs, when Ceplene is used in conjunction with IL-2, physicians should also refer to the Summary of Product Characteristics (SmPC) for IL-2 and observe the respective medical product interactions.

H2 receptor antagonists with imidazole structures similar to histamine, e.g., cimetidine, systemic steroids and clonidine, must not be used during treatment with Ceplene (see section 4.3).

Beta-blockers and other anti-hypertensive agents should be used with caution during treatment with Ceplene. Concurrent administration of medicinal products with cardiotoxicity or blood pressure lowering effects may increase the toxicity of Ceplene.

H1 receptor blocking antihistamines or neuroleptics (anti-psychotics) with H1 receptor blocking properties that might decrease efficacy of Ceplene should be avoided.

Tricyclic anti-depressants may have H1 and H2 receptor blocking properties and should be avoided.

Monoamine oxidase inhibitors, anti-malarial, and anti-trypanosomal active substances may alter the metabolism of Ceplene and should be avoided (see section 4.4).

It has been noted that neuromuscular blocking agents, narcotic analgesics, and various contrast media can induce the release of endogenous histamine; therefore in patients undergoing diagnostic or surgical procedures, the additive effect of Ceplene treatment should be considered prior to the procedure (see section 4.4).

4.6Fertility, pregnancy and lactation

Contraception in males and females

Women of childbearing potential and sexually active men must use effective methods of contraception during treatment with Ceplene and IL-2.

Pregnancy

For Ceplene, no clinical data on exposed pregnancies are available. Animal studies showed reproductive toxicity but only at maternotoxic doses, and did not indicate direct harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3). Ceplene in conjunction with IL-2 must not be used during pregnancy.

Breast-feeding

It is unknown whether histamine is excreted in human breast milk. The excretion of histamine in milk has not been studied in animals, but at maternotoxic doses in rats, offspring showed slight toxicity during early lactation (see section 5.3). Ceplene in conjunction with IL-2 must not be used during breast-feeding.

Refer to the IL-2 SmPC for information on pregnancy and lactation with IL-2.

Fertility

No clinical data are available on the effects of Ceplene on fertility. Animal studies revealed no adverse effects on fertility apart from a slight reduction in implantations and viable foetuses (see section 5.3).

4.7Effects on ability to drive and use machines

Ceplene has minor or moderate influence on the ability to drive and use machines. Administration of Ceplene can cause hypotension and may result in dizziness, light-headedness and blurred vision. Patients should not drive or operate machines for at least 1 hour after receiving Ceplene.

4.8Undesirable effects

Acute myeloid leukaemia

Adverse reactions were reported to be at least possibly related to IL-2 and Ceplene treatment in almost all patients in studies in AML.

The most common adverse reactions experienced by 30% or more of patients receiving IL-2 and Ceplene (listed in descending order of frequency) were: flushing, headache, fatigue, injection site granuloma, pyrexia and injection site erythema.

The adverse reactions considered at least possibly related to the treatment of low-dose IL-2 with Ceplene in AML studies (n=280 for the IL-2 and Ceplene treatment arm) are listed below by body system organ, class and frequency. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness. 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) and very rare (< 1/10,000). The ADRs identified only during post-marketing surveillance, and for which a frequency could not be estimated, are listed under “not known”.

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

Administration of Ceplene or IL-2 by rapid infusion or into vascular spaces, at higher doses than the approved ones, may exaggerate the adverse reactions associated with Ceplene.

5.PHARMACOLOGICAL PROPERTIES

5.1Pharmacodynamic properties

Pharmacotherapeutic group: Immunostimulants, other immunostimulants, ATC code: L03AX14.

Mechanism of action

Ceplene/IL-2 is an immunotherapy which aims to induce immune-mediated destruction of residual myeloid leukaemic cells and thereby to prevent relapse of leukaemia. The role of Ceplene is to protect lymphocytes, in particular NK cells and T cells, which are responsible for the immune- mediated destruction of residual leukaemic cells. The role of IL-2 is to promote the functions of NK cells and T cells by activating the anti-leukaemic properties of these cells and by expanding these cell populations by inducing cell cycle proliferation.

Pharmacodynamic effects

The mechanism by which Ceplene improves the anti-leukaemic function of lymphocytes in AML is not completely established; it is considered to be by inhibition of reactive oxygen species (ROS or ‘oxygen free radicals’), which are synthesised by monocytes/macrophages and granulocytes. ROS are known to limit the anti-leukaemic effects of lymphocyte activators such as IL-2, by triggering dysfunction and death by apoptosis in NK cells and T cells. Ceplene inhibits NAPDH oxidase which initiates the formation and release of ROS from phagocytes. By inhibiting oxidase function and reducing ROS production, Ceplene protects IL-2-activated NK cells and T cells from oxygen free

radical-induced inhibition and apoptosis. The concomitant administration of Ceplene and IL-2 therefore aims to optimise the anti-leukaemic functions of NK cells and T cells.

Clinical efficacy and safety

There have been 2 clinical studies to evaluate the use of Ceplene in the maintenance of remission in adult AML patients. Study AML-1 was exploratory, enrolling 39 AML patients in remission to determine the dose and feasibility of Ceplene administered together with IL-2. Results of this pilot study were used to design and implement a multi-national phase 3 trial. The randomised phase 3 trial (0201) compared Ceplene+IL-2 treatment to no treatment in 261 patients in first remission (CR1) and in another 59 patients in subsequent remission after relapse (CR>1). For CR1 patients, the median duration of leukaemia-free survival increased from 291 days (9.7 months) to 450 days (15 months) after Ceplene/IL-2 versus no maintenance treatment (ITT, p=0.01. n=261). The number of CR1 patients remaining leukaemia-free for 3 years was 40% after Ceplene+IL-2 versus 26% in patients not receiving this treatment (p=0.01).

This medicinal product has been authorised under ‘exceptional circumstances’. This means that due to the rarity of the disease it has not been possible to obtain complete information on this medicinal product. The European Medicines Agency will review any new information which may become available every year and this SmPC will be updated as necessary.

Paediatric population

Ceplene is indicated for use in adults. There are no data available on pharmacodynamic properties in children below 18 years of age.

5.2Pharmacokinetic properties

Absorption

Histamine is rapidly absorbed after subcutaneous injection. Maximum plasma concentration is reached approximately 10 minutes after end of subcutaneous infusion. Histamine concentrations and PK were highly variable across studies, as well as within the normal volunteer and patient groups.

Distribution

Patients showed a higher degree of variability with respect to systemic exposure as compared to healthy subjects. Overall systemic exposure of Ceplene was greater in patients versus healthy subjects. However, this difference was not statistically significant.

It is not known whether histamine crosses the placenta.

Biotransformation/Elimination

Histamine is eliminated by metabolism in kidney, liver and other tissues. The main enzymes involved in the metabolism of histamine are HNMT (histamine-N-methyltransferase) and DAO (diamine oxidase). The metabolites are mainly excreted in urine. The mean half-life was 0.75 to 1.5 hours in patients.

There are no significant effects of age or weight on the pharmacokinetic properties of histamine. Clearance of Ceplene is almost twice as high in females resulting in considerably lower systemic exposure than in males.

Renal impairment

The pharmacokinetics of histamine are similar in healthy volunteers with normal renal function compared to volunteers with mild, moderate, or severe renal impairment. In subjects with severe

renal impairment, there were decreases in systolic and diastolic blood pressure at plasma histamine concentrations which caused no appreciable decrease in blood pressure in other subjects. Thus, subjects with severe renal impairment may be more sensitive to the blood pressure lowering effects of exogenously administered histamine than subjects with normal renal function or subjects with mild or moderate renal impairment. Although the degree of renal impairment has little effect on the PK disposition of histamine, caution should be used in the administration of histamine to patients with severe renal impairment.

Hepatic impairment

A study was performed to measure the PK of histamine in normal volunteers compared to patients with mild, moderate, and severe hepatic impairment. There were no clinically significant differences in safety parameters or in pharmacodynamics. Plasma histamine concentrations were highly variable and were considerably higher in the groups of patients with moderate or severe hepatic impairment (medians 10 and 5 times the normal volunteers respectively). Patients with all degrees of hepatic impairment may have tachycardia or hypotension for 30-60 minutes after Ceplene+IL-2 administration.

5.3Preclinical safety data

Non-clinical data reveal no special hazard for humans based on conventional studies of repeated-dose toxicity, local tolerance and genotoxicity. Effects in non-clinical studies were observed only at exposures considered sufficiently in excess of the maximum human exposure, indicating little relevance to clinical use. No carcinogenicity studies have been performed on Ceplene.

Histamine dihydrochloride was not teratogenic in rats or rabbits at doses resulting in several hundredfold greater systemic exposures than the clinical exposure. In female rats dosed before mating to gestation day 7, slightly reduced numbers of implantations and viable foetuses were found, but without any dose-response and within the range of historical control data. In the peri-post natal development study, high doses of histamine dihydrochloride caused maternal toxicity, and the offspring showed toxicity during lactation (fewer live pups at day 21 compared to lactation at day 4) but not after weaning.

6.6Special precaution for disposal and other handling

Ceplene

The vials contain 0.70 mL of solution (including overfill) to facilitate the dose extraction of a single 0.5 mL dose.

Patients should be provided with capped polypropylene syringes and instructed to extract 0.5 mL of solution into the syringe.

The solution should be visually inspected for particulate matter and discolouration prior to administration. The solution must be clear and colourless.

Any unused product or waste material should be disposed of in accordance with local requirements.

Interleukin-2 (IL-2; aldesleukin)

Dilute IL-2 dispensed in capped polypropylene tuberculin syringes is to be prepared by the pharmacy in a controlled aseptic environment and stored in a refrigerator at 2°C – 8°C.

Initial reconstitution

Each vial of aldesleukin (1.3 mg / vial) is reconstituted aseptically with 1.2 mL water for injections (see commercially available aldesleukin SmPC). Direct the diluent against the side of the vial to avoid excessive foaming. Gently swirl to facilitate complete dissolution of the powder. Do NOT shake the vial during the entire reconstitution process. The resulting solution contains 22 x 10 6 IU (1,300 µg) of aldesleukin per 1.2 mL.

Subsequent dilution to 200 µg/mL

The entire contents of the reconstituted vial (1.2 mL) is then further diluted aseptically with 5.3 mL dextrose 5%w/v solution for injection to a total volume of 6.5 mL providing a final concentration of 200 µg/mL (3.3 x 106 IU/mL) of IL-2 (aldesleukin).

When reconstituted and diluted, stability of dilute IL-2 (aldesleukin) in capped polypropylene tuberculin syringes has been demonstrated for up to 21 days when stored at refrigerated temperatures (2°C – 8°C).

Please see section 4.2 for IL-2 dispensing instructions.
