Xamiol gel





1. Name Of The Medicinal Product



Xamiol 50 micrograms/g + 0.5 mg/g gel


2. Qualitative And Quantitative Composition



One gram of gel contains 50 micrograms of calcipotriol (as monohydrate) and 0.5 mg of betamethasone (as dipropionate).



Excipient: 160 micrograms butylated hydroxytoluene/g gel.



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Gel.



An almost clear, colourless to slightly off-white gel.



4. Clinical Particulars



4.1 Therapeutic Indications



Topical treatment of scalp psoriasis in adults.



4.2 Posology And Method Of Administration



Posology



Xamiol gel should be applied to affected areas once daily. The recommended treatment period is 4 weeks. If it is necessary to continue or restart treatment after this period, treatment should be continued after medical review and under regular medical supervision.



When using calcipotriol containing medicinal products, the maximum daily dose should not exceed 15 g. The body surface area treated with calcipotriol containing medicinal products should not exceed 30% (see section 4.4).



All the affected scalp areas may be treated with Xamiol gel. Usually an amount between 1 g and 4 g per day is sufficient for treatment of the scalp (4g corresponds to one teaspoon).



Special populations



Renal and hepatic impairment



The safety and efficacy of Xamiol gel in patients with severe renal insufficiency or severe hepatic disorders have not been evaluated.



Paediatric population



The safety and efficacy of Xamiol gel in children below 18 years have not been established. No data are available.



Method of administration



The bottle should be shaken before use and Xamiol gel applied to the affected area. Xamiol gel should not be applied directly to the face or eyes. The hands should be washed after use. In order to achieve optimal effect, it is not recommended to wash the hair immediately after application of Xamiol gel. Xamiol gel should remain on the scalp during the night or during the day.



4.3 Contraindications



Hypersensitivity to the active substances or to any of the excipients.



Xamiol gel is contraindicated in erythrodermic, exfoliative and pustular psoriasis.



Due to the content of calcipotriol, Xamiol gel is contraindicated in patients with known disorders of calcium metabolism.



Due to the content of corticosteroid, Xamiol gel is contraindicated in the following conditions: Viral (e.g. herpes or varicella) lesions of the skin, fungal or bacterial skin infections, parasitic infections, skin manifestations in relation to tuberculosis or syphilis, perioral dermatitis, atrophic skin, striae atrophicae, fragility of skin veins, ichthyosis, acne vulgaris, acne rosacea, rosacea, ulcers, wounds, perianal and genital pruritus.



4.4 Special Warnings And Precautions For Use



Effects on endocrine system



Xamiol gel contains a potent group III steroid and concurrent treatment with other steroids on the scalp must be avoided. Adverse reactions found in connection with systemic corticosteroid treatment, such as adrenocortical suppression or impact on the metabolic control of diabetes mellitus, may occur also during topical corticosteroid treatment due to systemic absorption. Application under occlusive dressings should be avoided since it increases the systemic absorption of corticosteroids. Application on large areas of damaged skin or on mucous membranes or in skin folds should be avoided since it increases the systemic absorption of corticosteroids (see section 4.8).



In a study in patients with both extensive scalp and extensive body psoriasis using a combination of high doses of Xamiol gel (scalp application) and high doses of Dovobet ointment (body application), 5 of 32 patients showed a borderline decrease in cortisol response to adrenocorticotropic hormone (ACTH) challenge after 4 weeks of treatment (see section 5.1).



Effects on calcium metabolism



Due to the content of calcipotriol, hypercalcaemia may occur if the maximum daily dose (15 g) is exceeded. Serum calcium is, however, quickly normalised when treatment is discontinued. The risk of hypercalcaemia is minimal when the recommendations relevant to calcipotriol are followed.



Treatment of more than 30% of the body surface should be avoided (see section 4.2).



Local adverse reactions



Skin of the face and genitals are very sensitive to corticosteroids. The medicinal product should not be used in these areas. Uncommon local adverse reactions (such as eye irritation or irritation of facial skin) were observed, when the medicinal product was accidentally administered in the area of face, or accidentally to the eyes or conjunctives (see sections 4.8 and 5.1). The patient must be instructed in correct use of the medicinal product to avoid application and accidental transfer to the face, mouth and eyes. Hands must be washed after each application to avoid accidental transfer to these areas.



Concomitant skin infections



When lesions become secondarily infected, they should be treated with antimicrobiological therapy. However, if infection worsens, treatment with corticosteroids should be stopped.



Discontinuation of treatment



When treating psoriasis with topical corticosteroids, there may be a risk of generalised pustular psoriasis or of rebound effects when discontinuing treatment. Medical supervision should therefore continue in the post-treatment period.



Long-term use



With long-term use there is an increased risk of local and systemic corticosteroid adverse reactions. The treatment should be discontinued in case of adverse reactions related to long-term use of corticosteroid (see section 4.8).



Unevaluated uses



There is no experience for the use of Xamiol gel in guttate psoriasis.



Concurrent treatment and UV exposure



Dovobet ointment for body psoriasis lesions has been used in combination with Xamiol gel for scalp psoriasis lesions, but there is no experience of combination of Xamiol with other topical anti-psoriatic products at the same treatment area, other anti-psoriatic medicinal products administered systemically or with phototherapy.



During Xamiol gel treatment, physicians are recommended to advise patients to limit or avoid excessive exposure to either natural or artificial sunlight. Topical calcipotriol should be used with UVR only if the physician and patient consider that the potential benefits outweigh the potential risks (see section 5.3).



Adverse reactions to excipients



Xamiol gel contains butylated hydroxytoluene (E321), which may cause local skin reactions (e.g. contact dermatitis), or irritation to the eyes and mucous membranes.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



No interaction studies have been performed.



4.6 Pregnancy And Lactation



Pregnancy



There are no adequate data from the use of Xamiol gel in pregnant women. Studies in animals with glucocorticoids have shown reproductive toxicity (see section 5.3), but a number of epidemiological studies have not revealed congenital anomalies among infants born to women treated with corticosteroids during pregnancy. The potential risk for humans is uncertain. Therefore, during pregnancy, Xamiol gel should only be used when the potential benefit justifies the potential risk.



Breastfeeding



Betamethasone passes into breast milk, but risk of an adverse effect on the infant seems unlikely with therapeutic doses. There are no data on the excretion of calcipotriol in breast milk. Caution should be exercised when prescribing Xamiol gel to women who breast-feed.



Fertility



Studies in rats with oral doses of calcipotriol or betamethasone dipropionate demonstrated no impairment of male and female fertility



4.7 Effects On Ability To Drive And Use Machines



Xamiol gel has no influence on the ability to drive and use machines.



4.8 Undesirable Effects



The clinical trial programme for Xamiol gel has so far included more than 4,400 patients of whom more than 1,900 were treated with Xamiol gel. Approximately 8% of patients treated with Xamiol gel experienced a non-serious adverse reaction.



These reactions are usually mild and cover mainly various skin reactions with pruritus being the most common.



Based on data from clinical trials and postmarket use the following adverse reactions are listed for Xamiol gel.



The adverse reactions are listed by MedDRA System Organ Class, and the individual adverse reactions are listed starting with the most frequently reported. Within each frequency grouping, the adverse reactions are listed in order of decreasing seriousness.



The following terminologies have been used in order to classify the frequencies of adverse reactions:














Very common




1/10

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



Not known (cannot be estimated from the available data)

Common




Pruritus




Uncommon




Exacerbation of psoriasis



Burning sensation of skin



Skin pain or irritation



Folliculitis



Dermatitis



Erythema



Acne



Dry skin



Rash



Pustular rash



The following adverse reactions are considered to be related to the pharmacological classes of calcipotriol and betamethasone, respectively:



Calcipotriol



Adverse reactions include application site reactions, pruritus, skin irritation, burning and stinging sensation, dry skin, erythema, rash, dermatitis, eczema, psoriasis aggravated, photosensitivity and hypersensitivity reactions including very rare cases of angioedema and facial oedema. Systemic effects after topical use may appear very rarely causing hypercalcaemia or hypercalciuria (see section 4.4).



Betamethasone (as dipropionate)



Local reactions can occur after topical use, especially during prolonged application, including skin atrophy, telangiectasia, striae, folliculitis, hypertrichosis, perioral dermatitis, allergic contact dermatitis, depigmentation and colloid milia. When treating psoriasis, there may be a risk of generalised pustular psoriasis.



Systemic reactions due to topical use of corticosteroids are rare in adults, however they can be severe. Adrenocortical suppression, cataract, infections, impact on the metabolic control of diabetes mellitus and increase of intra-ocular pressure can occur, especially after long-term treatment. Systemic reactions occur more frequently when applied under occlusion (plastic, skin folds), when applied on large areas and during long-term treatment (see section 4.4).



4.9 Overdose



Use above the recommended dose may cause elevated serum calcium which should rapidly subside when treatment is discontinued.



Excessive prolonged use of topical corticosteroids may suppress the pituitary-adrenal functions, resulting in secondary adrenal insufficiency which is usually reversible. In such cases, symptomatic treatment is indicated.



In case of chronic toxicity, the corticosteroid treatment must be discontinued gradually.



It has been reported that due to misuse one patient with extensive erythrodermic psoriasis treated with 240 g of Dovobet ointment weekly (corresponding to a daily dose of approximately 34g) for 5 months (maximum recommended dose 15g daily) developed Cushing's syndrome and pustular psoriasis after abruptly stopping treatment.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Antipsoriatics. Other antipsoriatics for topical use, Calcipotriol, combinations.



ATC Code: D05AX52



Calcipotriol is a vitamin D analogue. In vitro data suggest that calcipotriol induces differentiation and suppresses proliferation of keratinocytes. This is the proposed basis for its effect in psoriasis.



Like other topical corticosteroids, betamethasone dipropionate has anti-inflammatory, antipruritic, vasoconstrictive and immunosuppresive properties, however, without curing the underlying condition. Through occlusion the effect can be enhanced due to increased penetration of the stratum corneum. The incidence of adverse events will increase because of this. In general, the mechanism of the anti-inflammatory activity of the topical steroids is unclear.



Adrenal response to ACTH was determined by measuring serum cortisol levels in patients with both extensive scalp and body psoriasis, using up to 106 g per week combined Xamiol gel and Dovobet ointment. A borderline decrease in cortisol response at 30 minutes post ACTH challenge was seen in 5 of 32 patients (15.6%) after 4 weeks of treatment and in 2 of 11 patients (18.2%) who continued treatment until 8 weeks. In all cases, the serum cortisol levels were normal at 60 minutes post ACTH challenge. There was no evidence of change of calcium metabolism observed in these patients. With regard to HPA suppression, therefore, this study shows some evidence that very high doses of Xamiol gel and Dovobet ointment may have a weak effect on the HPA axis.



The efficacy of once daily use of Xamiol gel was investigated in two randomised, double-blind, 8-week clinical studies including a total of more than 2,900 patients with scalp psoriasis of at least mild severity according to the Investigator's Global Assessment of disease severity (IGA). Comparators were betamethasone dipropionate in the gel vehicle, calcipotriol in the gel vehicle and (in one of the studies) the gel vehicle alone, all used once daily. Results for the primary response criterion (absent or very mild disease according to the IGA at week 8) showed that Xamiol gel was statistically significantly more effective than the comparators. Results for speed of onset based on similar data at week 2 also showed Xamiol gel to be statistically significantly more effective than the comparators.

Another randomised, investigator-blinded clinical study including 312 patients with scalp psoriasis of at least moderate severity according to the IGA investigated use of Xamiol gel once daily compared with Dovonex Scalp solution twice daily for up to 8 weeks. Results for the primary response criterion (absent or very mild disease according to the IGA at week 8) showed that Xamiol gel was statistically significantly more effective than Dovonex Scalp solution.

1 Statistically significantly less effective than Xamiol gel (P<0.001)



A randomised, double-blind long-term clinical study including 873 patients with scalp psoriasis of at least moderate severity (according to the IGA) investigated the use of Xamiol gel compared with calcipotriol in the gel vehicle. Both treatments were applied once daily, intermittently as required, for up to 52 weeks. Adverse events possibly related to long-term use of corticosteroids on the scalp, were identified by an independent, blinded panel of dermatologists. There was no difference in the percentages of patients experiencing such adverse events between the treatment groups (2.6% in the Xamiol gel group and 3.0% in the calcipotriol group; P=0.73). No cases of skin atrophy were reported.



5.2 Pharmacokinetic Properties



The systemic exposure to calcipotriol and betamethasone dipropionate from topically applied Xamiol gel is comparable to Dovobet ointment in rats and minipigs. Clinical studies with radiolabelled ointment indicate that the systemic absorption of calcipotriol and betamethasone from Dovobet ointment formulation is less than 1% of the dose (2.5 g) when applied to normal skin (625 cm2) for 12 hours. Application to psoriasis plaques and under occlusive dressings may increase the absorption of topical corticosteroids. Absorption through damaged skin is approx. 24 %.



Following systemic exposure, both active ingredients – calcipotriol and betamethasone dipropionate – are rapidly and extensively metabolised. Protein binding is approx. 64 %. Plasma elimination half-life after intravenous application is 5-6 hours. Due to the formation of a depot in the skin elimination after dermal application is in order of days. Betamethasone is metabolised especially in the liver, but also in the kidneys to glucuronide and sulphate esters. The main route of excretion of calcipotriol is via faeces (rats and minipigs) and for betamethasone dipropionate it is via urine (rats and mice). In rats, tissue distribution studies with radiolabelled calcipotriol and betamethasone dipropionate, respectively, showed that the kidney and liver had the highest level of radioactivity.



Calcipotriol and betamethasone dipropionate were below the lower limit of quantification in all blood samples of 34 patients treated for 4 or 8 weeks with both Xamiol gel and Dovobet ointment for extensive psoriasis involving the body and scalp. One metabolite of calcipotriol and one metabolite of betamethasone dipropionate were quantifiable in some of the patients.



5.3 Preclinical Safety Data



Studies of corticosteroids in animals have shown reproductive toxicity (cleft palate, skeletal malformations). In reproduction toxicity studies with long-term oral administration of corticosteroids to rats, prolonged gestation and prolonged and difficult labour were detected. Moreover, reduction in offspring survival, body weight and body weight gain was observed. There was no impairment of fertility. The relevance for humans is unknown.



A dermal carcinogenicity study with calcipotriol in mice revealed no special hazard to humans.



Photo(co)carcinogenicity studies in mice suggest that calcipotriol may enhance the effect of UVR to induce skin tumours.



No carcinogenicity or photocarcinogenicity studies have been performed with betamethasone dipropionate.



In local tolerability studies in rabbits, Xamiol gel caused mild to moderate skin irritation and a slight transient irritation of the eye.

Posology adjustments during treatment:



General



Toxicity due to Xeloda administration may be managed by symptomatic treatment and/or modification of the dose (treatment interruption or dose reduction). Once the dose has been reduced, it should not be increased at a later time. For those toxicities considered by the treating physician to be unlikely to become serious or life-threatening, e.g. alopecia, altered taste, nail changes, treatment can be continued at the same dose without reduction or interruption. Patients taking Xeloda should be informed of the need to interrupt treatment immediately if moderate or severe toxicity occurs. Doses of Xeloda omitted for toxicity are not replaced. The following are the recommended dose modifications for toxicity:

*According to the National Cancer Institute of Canada Clinical Trial Group (NCIC CTG) Common Toxicity Criteria (version 1) or the Common Terminology Criteria for Adverse Events (CTCAE) of the Cancer Therapy Evaluation Program, US National Cancer Institute, version 3.0. For hand-foot syndrome and hyperbilirubinemia, see section 4.4.



Haematology: Patients with baseline neutrophil counts of <1.5 x 109/L and/or thrombocyte counts of <100 x 109/L should not be treated with Xeloda. If unscheduled laboratory assessments during a treatment cycle show that the neutrophil count drops below 1.0 x 109/L or that the platelet count drops below 75 x 109/L, treatment with Xeloda should be interrupted.



Dose modifications for toxicity when Xeloda is used as a 3 weekly cycle in combination with other agents:



Dose modifications for toxicity when Xeloda is used as a 3 weekly cycle in combination with other agents should be made according to Table 3 above for Xeloda and according to the appropriate summary of product characteristics for the other agent(s).



At the beginning of a treatment cycle, if a treatment delay is indicated for either Xeloda or the other agent(s), then administration of all agents should be delayed until the requirements for restarting all drugs are met.



During a treatment cycle for those toxicities considered by the treating physician not to be related to Xeloda, Xeloda should be continued and the dose of the other agent should be adjusted according to the appropriate Prescribing Information.



If the other agent(s) have to be discontinued permanently, Xeloda treatment can be resumed when the requirements for restarting Xeloda are met.



This advice is applicable to all indications and to all special populations.



Dose modifications for toxicity when Xeloda is used continuously in combination with other agents:



Dose modifications for toxicity when Xeloda is used continuously in combination with other agents should be made according to Table 3 above for Xeloda and according to the appropriate summary of product characteristics for the other agent(s).



Posology adjustments for special populations:



Hepatic impairment: insufficient safety and efficacy data are available in patients with hepatic impairment to provide a dose adjustment recommendation. No information is available on hepatic impairment due to cirrhosis or hepatitis.



Renal impairment: Xeloda is contraindicated in patients with severe renal impairment (creatinine clearance below 30 ml/min [Cockcroft and Gault] at baseline). The incidence of grade 3 or 4 adverse reactions in patients with moderate renal impairment (creatinine clearance 30-50 ml/min at baseline) is increased compared to the overall population. In patients with moderate renal impairment at baseline, a dose reduction to 75% for a starting dose of 1250 mg/m2 is recommended. In patients with moderate renal impairment at baseline, no dose reduction is required for a starting dose of 1000 mg/m2. In patients with mild renal impairment (creatinine clearance 51-80 ml/min at baseline) no adjustment of the starting dose is recommended. Careful monitoring and prompt treatment interruption is recommended if the patient develops a grade 2, 3 or 4 adverse event during treatment and subsequent dose adjustment as outlined in Table 3 above. If the calculated creatinine clearance decreases during treatment to a value below 30 ml/min, Xeloda should be discontinued. These dose adjustment recommendations for renal impairment apply both to monotherapy and combination use (see also section “Elderly” below).



There is no experience in children (under 18 years).



Elderly:



During Xeloda monotherapy, no adjustment of the starting dose is needed. However, grade 3 or 4 treatment-related adverse reactions were more frequent in patients



When Xeloda was used in combination with other agents, elderly patients (



- In combination with docetaxel: an increased incidence of grade 3 or 4 treatment-related adverse reactions and treatment-related serious adverse reactions were observed in patients 60 years of age or more (see section 5.1). For patients 60 years of age or more , a starting dose reduction of Xeloda to 75% (950 mg/m2 twice daily) is recommended. If no toxicity is observed in patients 2 twice daily.



- In combination with irinotecan: for patients 65 years of age or more, a starting dose reduction of Xeloda to 800 mg/m2 twice daily is recommended.



4.3 Contraindications



• History of severe and unexpected reactions to fluoropyrimidine therapy,



• Hypersensitivity to capecitabine or to any of the excipients or fluorouracil,



• In patients with known dihydropyrimidine dehydrogenase (DPD) deficiency,



• During pregnancy and lactation,



• In patients with severe leucopenia, neutropenia, or thrombocytopenia,



• In patients with severe hepatic impairment,



• In patients with severe renal impairment (creatinine clearance below 30 ml/min),



• Treatment with sorivudine or its chemically related analogues, such as brivudine (see section 4.5),



• If contraindications exist to any of the agents in the combination regimen, that agent should not be used.



4.4 Special Warnings And Precautions For Use



Dose limiting toxicities include diarrhoea, abdominal pain, nausea, stomatitis and hand-foot syndrome (hand-foot skin reaction, palmar-plantar erythrodysesthesia). Most adverse reactions are reversible and do not require permanent discontinuation of therapy, although doses may need to be withheld or reduced.



Diarrhoea. Patients with severe diarrhoea should be carefully monitored and given fluid and electrolyte replacement if they become dehydrated. Standard antidiarrhoeal treatments (e.g. loperamide) may be used. NCIC CTC grade 2 diarrhoea is defined as an increase of 4 to 6 stools/day or nocturnal stools, grade 3 diarrhoea as an increase of 7 to 9 stools/day or incontinence and malabsorption. Grade 4 diarrhoea is an increase of



Dehydration. Dehydration should be prevented or corrected at the onset. Patients with anorexia, asthenia, nausea, vomiting or diarrhoea may rapidly become dehydrated. If Grade 2 (or higher) dehydration occurs, Xeloda treatment should be immediately interrupted and the dehydration corrected. Treatment should not be restarted until the patient is rehydrated and any precipitating causes have been corrected or controlled. Dose modifications applied should be applied for the precipitating adverse event as necessary (see section 4.2).



Hand-foot syndrome (also known as hand-foot skin reaction or palmar-plantar erythrodysesthesia or chemotherapy induced acral erythema). Grade 1 hand- foot syndrome is defined as numbness, dysesthesia/paresthesia, tingling, painless swelling or erythema of the hands and/or feet and/or discomfort which does not disrupt the patient's normal activities.



Grade 2 hand- foot syndrome is painful erythema and swelling of the hands and/or feet and/or discomfort affecting the patient's activities of daily living.



Grade 3 hand- foot syndrome is moist desquamation, ulceration, blistering and severe pain of the hands and/or feet and/or severe discomfort that causes the patient to be unable to work or perform activities of daily living. If grade 2 or 3 hand- foot syndrome occurs, administration of Xeloda should be interrupted until the event resolves or decreases in intensity to grade 1. Following grade 3 hand- foot syndrome, subsequent doses of Xeloda should be decreased. When Xeloda and cisplatin are used in combination, the use of vitamin B6 (pyridoxine) is not advised for symptomatic or secondary prophylactic treatment of hand–foot syndrome, because of published reports that it may decrease the efficacy of cisplatin.



Cardiotoxicity. Cardiotoxicity has been associated with fluoropyrimidine therapy, including myocardial infarction, angina, dysrhythmias, cardiogenic shock, sudden death and electrocardiographic changes (including very rare cases of QT prolongation). These adverse reactions may be more common in patients with a prior history of coronary artery disease. Cardiac arrhythmias (including ventricular fibrillation, torsade de pointes, and bradycardia), angina pectoris, myocardial infarction, heart failure and cardiomyopathy have been reported in patients receiving Xeloda. Caution must be exercised in patients with history of significant cardiac disease, arrhythmias and angina pectoris (See section 4.8).



Hypo- or hypercalcaemia. Hypo- or hypercalcaemia has been reported during Xeloda treatment. Caution must be exercised in patients with pre-existing hypo- or hypercalcaemia (see section 4.8).



Central or peripheral nervous system disease. Caution must be exercised in patients with central or peripheral nervous system disease, e.g. brain metastasis or neuropathy (see section 4.8).



Diabetes mellitus or electrolyte disturbances. Caution must be exercised in patients with diabetes mellitus or electrolyte disturbances, as these may be aggravated during Xeloda treatment.



Coumarin-derivative anticoagulation. In a drug interaction study with single-dose warfarin administration, there was a significant increase in the mean AUC (+57%) of S-warfarin. These results suggest an interaction, probably due to an inhibition of the cytochrome P450 2C9 isoenzyme system by capecitabine. Patients receiving concomitant Xeloda and oral coumarin-derivative anticoagulant therapy should have their anticoagulant response (INR or prothrombin time) monitored closely and the anticoagulant dose adjusted accordingly (see section 4.5).



Hepatic impairment. In the absence of safety and efficacy data in patients with hepatic impairment, Xeloda use should be carefully monitored in patients with mild to moderate liver dysfunction, regardless of the presence or absence of liver metastasis. Administration of Xeloda should be interrupted if treatment-related elevations in bilirubin of >3.0 x ULN or treatment-related elevations in hepatic aminotransferases (ALT, AST) of >2.5 x ULN occur. Treatment with Xeloda monotherapy may be resumed when bilirubin decreases to



Renal impairment. The incidence of grade 3 or 4 adverse reactions in patients with moderate renal impairment (creatinine clearance 30-50 ml/min) is increased compared to the overall population (see section 4.2 and 4.3).



As this medicinal product contains anhydrous lactose as an excipient, patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Interaction studies have only been performed in adults.



Interaction with other medicinal products:



Coumarin-derivative anticoagulants: altered coagulation parameters and/or bleeding have been reported in patients taking Xeloda concomitantly with coumarin-derivative anticoagulants such as warfarin and phenprocoumon. These reactions occurred within several days and up to several months after initiating Xeloda therapy and, in a few cases, within one month after stopping Xeloda. In a clinical pharmacokinetic interaction study, after a single 20 mg dose of warfarin, Xeloda treatment increased the AUC of S-warfarin by 57% with a 91% increase in INR value. Since metabolism of R-warfarin was not affected, these results indicate that capecitabine down-regulates isozyme 2C9, but has no effect on isozymes 1A2 and 3A4. Patients taking coumarin-derivative anticoagulants concomitantly with Xeloda should be monitored regularly for alterations in their coagulation parameters (PT or INR) and the anti-coagulant dose adjusted accordingly.



Phenytoin: increased phenytoin plasma concentrations resulting in symptoms of phenytoin intoxication in single cases have been reported during concomitant use of Xeloda with phenytoin. Patients taking phenytoin concomitantly with Xeloda should be regularly monitored for increased phenytoin plasma concentrations.



Folinic acid: a combination study with Xeloda and folinic acid indicated that folinic acid has no major effect on the pharmacokinetics of Xeloda and its metabolites. However, folinic acid has an effect on the pharmacodynamics of Xeloda and its toxicity may be enhanced by folinic acid: the maximum tolerated dose (MTD) of Xeloda alone using the intermittent regimen is 3000 mg/m2 per day whereas it is only 2000 mg/m2 per day when Xeloda was combined with folinic acid (30 mg orally bid).



Sorivudine and analogues: a clinically significant drug-drug interaction between sorivudine and 5-FU, resulting from the inhibition of dihydropyrimidine dehydrogenase by sorivudine, has been described. This interaction, which leads to increased fluoropyrimidine toxicity, is potentially fatal. Therefore, Xeloda must not be administered concomitantly with sorivudine or its chemically related analogues, such as brivudine (see section 4.3). There must be at least a 4-week waiting period between end of treatment with sorivudine or its chemically related analogues such as brivudine and start of Xeloda therapy.



Antacid: the effect of an aluminum hydroxide and magnesium hydroxide-containing antacid on the pharmacokinetics of capecitabine was investigated. There was a small increase in plasma concentrations of capecitabine and one metabolite (5'-DFCR); there was no effect on the 3 major metabolites (5'-DFUR, 5-FU and FBAL).



Allopurinol: interactions with allopurinol have been observed for 5-FU; with possible decreased efficacy of 5-FU. Concomitant use of allopurinol with Xeloda should be avoided.



Interaction with cytochrome P-450: For potential interactions with isozymes 1A2, 2C9 and 3A4, see interactions with coumarin-derivative anticoagulation.



Interferon alpha: the MTD of Xeloda was 2000 mg/m2 per day when combined with interferon alpha-2a (3 MIU/m2 per day) compared to 3000 mg/m2 per day when Xeloda was used alone.



Radiotherapy: the MTD of Xeloda alone using the intermittent regimen is 3000 mg/m2 per day, whereas, when combined with radiotherapy for rectal cancer, the MTD of Xeloda is 2000 mg/m2 per day using either a continuous schedule or given daily Monday through Friday during a 6-week course of radiotherapy.



Oxaliplatin: no clinically significant differences in exposure to capecitabine or its metabolites, free platinum or total platinum occurred when capecitabine was administered in combination with oxaliplatin or in combination with oxaliplatin and bevacizumab.



Bevacizumab: there was no clinically significant effect of bevacizumab on the pharmacokinetic parameters of capecitabine or its metabolites in the presence of oxaliplatin.



Food interaction: In all clinical trials, patients were instructed to administer Xeloda within 30 minutes after a meal. Since current safety and efficacy data are based upon administration with food, it is recommended that Xeloda be administered with food. Administration with food decreases the rate of capecitabine absorption (see section 5.2).



4.6 Pregnancy And Lactation



Women of childbearing potential



Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with Xeloda. If the patient becomes pregnant while receiving Xeloda, the potential hazard to the foetus must be explained.



Pregnancy



There are no studies in pregnant women using Xeloda; however, it should be assumed that Xeloda may cause foetal harm if administered to pregnant women. In reproductive toxicity studies in animals, Xeloda administration caused embryolethality and teratogenicity. These findings are expected effects of fluoropyrimidine derivatives. Xeloda is contraindicated during pregnancy.



Breastfeeding



It is not known whether Xeloda is excreted in human breast milk. In lactating mice, considerable amounts of capecitabine and its metabolites were found in milk. Breast-feeding should be discontinued while receiving treatment with Xeloda.



4.7 Effects On Ability To Drive And Use Machines



Xeloda has minor or moderate influence on the ability to drive and use machines. Xeloda may cause dizziness, fatigue and nausea.



4.8 Undesirable Effects



a. Summary of the safety profile



The overall safety profile of Xeloda is based on data from over 3000 patients treated with Xeloda as monotherapy or Xeloda in combination with different chemotherapy regimens in multiple indications. The safety profiles of Xeloda monotherapy for the metastatic breast cancer, metastatic colorectal cancer and adjuvant colon cancer populations are comparable. See section 5.1 for details of major studies, including study designs and major efficacy results.



The most commonly reported and/or clinically relevant treatment-related adverse drug reactions (ADRs) were gastrointestinal disorders (especially diarrhoea, nausea, vomiting, abdominal pain, stomatitis), hand-foot syndrome (palmar-plantar erythrodysesthesia), fatigue, asthenia, anorexia, cardiotoxicity, increased renal dysfunction on those with preexisting compromised renal function, and thrombosis/embolism.



b. Tabulated summary of adverse reactions



ADRs considered by the investigator to be possibly, probably, or remotely related to the administration of Xeloda are listed in Table 4 for Xeloda given as a single agent and in Table 5 for Xeloda given in combination with different chemotherapy regimens in multiple indications. The following headings are used to rank the ADRs by frequency: very common (

Xatral





1. Name Of The Medicinal Product



Xatral 2.5 mg film coated tablet


2. Qualitative And Quantitative Composition



Each tablet contains 2.5mg alfuzosin hydrochloride.



Excipient: Lactose



For a full list of excipients, see section 6.1



3. Pharmaceutical Form



Film coated tablet.



White round tablet marked Xatral 2.5 on one side.



4. Clinical Particulars



4.1 Therapeutic Indications



Treatment of the functional symptoms of benign prostatic hypertrophy.



4.2 Posology And Method Of Administration



Xatral tablets should be swallowed whole. The first dose should be given just before bedtime.



Adults



The usual dose is one tablet three times daily. The dose may be increased to a maximum of 4 tablets (10mg) per day depending on the clinical response.



Elderly and treated hypertensive patients



As a routine precaution when prescribing alfuzosin to elderly patients (aged over 65 years) and the treated hypertensive patient, the initial dose should be 1 tablet in the morning and 1 tablet in the evening.



Renal insufficiency



In patients with renal insufficiency, as a precaution, it is recommended that the dosing be started at Xatral 2.5mg twice daily adjusted according to clinical response.



Hepatic insufficiency



In patients with mild to moderate hepatic insufficiency, it is recommended that therapy should commence with a single dose of Xatral 2.5mg/day to be increased to Xatral 2.5mg twice daily according to clinical response.



Paediatric population



Efficacy of alfuzosin has not been demonstrated in children aged 2 to 16 years (see section 5.1). Therefore, alfuzosin is not indicated for use in the paediatric population.



4.3 Contraindications



• Hypersensitivity to the active substance or any of the excipients (see Section 6.1 List of excipients);



• history of orthostatic hypotension;



• combination with other alpha-1 receptor blockers;



• severe hepatic insufficiency.



4.4 Special Warnings And Precautions For Use



As with all alpha-1-blockers, in some subjects, in particular patients receiving antihypertensive medications or nitrates, postural hypotension with or without symptoms (dizziness, fatigue, sweating) may develop within a few hours following administration. In such cases, the patient should lie down until the symptoms have completely disappeared.



These effects are transient, occur at the beginning of treatment and do not usually prevent the continuation of treatment. The patient should be warned of the possible occurrence of such events.



As with all alpha-1-receptor blockers, alfuzosin should be used with caution in patients with acute cardiac failure.



Patients with congenital QTc prolongation, with a known history of acquired QTc prolongation or who are taking drugs known to increase the QTc interval should be evaluated before and during the administration of alfuzosin.



There is a risk of cerebral ischemic disorders in patients with symptomatic or asymptomatic pre-existing cerebral circulatory disturbances, due to the fact that hypotension may develop following alfuzosin administration.



Care should be taken when Xatral is administered to patients who have a pronounced hypotensive response to another alpha-1-blocker. Treatment should be initiated gradually in patients with hypersensitivity to alpha-1-blockers. Xatral should be administered carefully to patients being treated with antihypertensives. Blood pressure should be monitored regularly, especially at the beginning of treatment.



In coronary patients, the specific treatment for coronary insufficiency should be continued. If angina pectoris reappears or worsens Xatral should be discontinued.



The ‘Intraoperative Floppy Iris Syndrome’ (IFIS, a variant of small pupil syndrome) has been observed during cataract surgery in some patients on or previously treated with alpha-1-blockers. Although the risk of this event with alfuzosin appears very low, ophthalmic surgeons should be informed in advance of cataract surgery of current or past use of alpha-1-blockers, as IFIS may lead to increased procedural complications. The ophthalmologists should be prepared for possible modifications to their surgical technique.



Alfuzosin 2.5 mg film-coated tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Combinations contraindicated:



- Alpha-1-receptor blockers (see section 4.3)



Combinations to be taken into account:



- Antihypertensive drugs (see section 4.4.2)



- Nitrates



- potent CYP3A4 inhibitors such as ketoconazole, itraconazole and ritonavir.



Repeated 200 mg daily dosing of ketoconazole, for seven days resulted in a 2.1-fold increase in Cmax and a 2.5-fold increase in exposure of alfuzosin 10 mg when administered as a single dose under fed conditions (high fat meal). Other parameters such as tmax and t1/2 were not modified. Cmax and AUC of alfuzosin 10 mg, when administered as a single dose under fed conditions, increased 2.3- fold and 3.0- fold, respectively following 8-day repeated 400 mg ketoconazole daily dosing (see section 5.2)



The administration of general anaesthetics to patients receiving Xatral could cause profound hypotension. It is recommended that Xatral be withdrawn 24 hours before surgery.



Other forms of interaction



No pharmacodynamic or pharmacokinetic interaction has been observed in healthy volunteers between alfuzosin and the following drugs: warfarin, digoxin, hydrochlorothiazide and atenolol.



4.6 Pregnancy And Lactation



Due to the type of indication this section is not applicable.



4.7 Effects On Ability To Drive And Use Machines



There are no data available on the effect on driving vehicles. Adverse reactions such as vertigo, dizziness and asthenia may occur essentially at the beginning of treatment. This has to be taken into account when driving vehicles and operating machinery.



4.8 Undesirable Effects

4.9 Overdose



In case of overdosage, the patient should be hospitalised, kept in the supine position, and conventional treatment of hypotension should take place.



In case of significant hypotension, the appropriate corrective treatment may be a vasoconstrictor that acts directly on vascular muscle fibres.



Alfuzosin is not easily dialysable because of its high degree of protein binding.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Alfuzosin is an orally active quinazoline derivative. It is a selective, peripherally acting antagonist of post synaptic alpha-1-adrenoceptors.



Pharmacotherapeutic group: alpha-adrenoreceptor antagonists



ATC code: G04CA01



In vitro pharmacological studies have documented the selectivity of alfuzosin for the alpha1-adrenoreceptors located in the prostate, bladder base and prostatic urethra.



Clinical manifestations of Benign Prostatic Hypertrophy are associated with infra vesical obstruction which is triggered by both anatomical (static) and functional (dynamic) factors. The functional component of obstruction arises from the tension of prostatic smooth muscle which is mediated by alpha-adrenoceptors. Activation of alpha-1-adrenoceptors stimulates smooth muscle contraction, thereby increasing the tone of the prostate, prostatic capsule, prostatic urethra and bladder base, and, consequently, increasing the resistance to bladder outflow. This in turn leads to outflow obstruction and possible secondary bladder instability.



Alpha-blockade decreases infra vesical obstruction via a direct action on prostatic smooth muscle.



In vivo, animal studies have shown that alfuzosin decreases urethral pressure and therefore, resistance to urine flow during micturition. Moreover, alfuzosin inhibits the hypertonic response of the urethra more readily than that of vascular muscle and shows functional uroselectivity in conscious normotensive rats by decreasing urethral pressure at doses that do not affect blood pressure.



In man, alfuzosin improves voiding parameters by reducing urethral tone and bladder outlet resistance, and facilitates bladder emptying.



In placebo controlled studies in BPH patients, alfuzosin:



significantly increases peak flow rate (Qmax) in patients with Qmax



These favourable urodynamic effects lead to an improvement of lower urinary tract symptoms ie. filling (irritative) as well as voiding (obstructive) symptoms.



Alfuzosin may cause moderate antihypertensive effects.



Paediatric population



Alfuzosin is not indicated for use in the paediatric population (see section 4.2).



Efficacy of alfuzosin hydrochloride was not demonstrated in the two studies conducted in 197 patients 2 to 16 years of age with elevated detrusor leak point pressure (LPP2O) of neurological origin. Patients were treated with alfuzosin hydrochloride 0.1 mg/kg/day or 0.2 mg/kg/day using adapted paediatric formulations.



5.2 Pharmacokinetic Properties



Xatral is well absorbed with a mean bioavailability of 64%, peak plasma levels are generally reached in 0.5-3 hours. Kinetics within the therapeutic range are linear. The kinetic profile is characterised by large interindividual fluctuations in plasma concentrations. The terminal half-life is 3-5 hours. Alfuzosin is 90% protein bound in plasma, 68.2% to human serum albumin and 52.5% to human serum alpha-glycoprotein. It is partially metabolised and excreted mainly in the bile and faeces.



None of the metabolites found in man has any pharmacodynamic activity. The pharmacokinetic profile is not affected by taking Xatral with food.



In subjects over 75 years, absorption is more rapid and peak plasma levels are higher. Bioavailability may be increased and in some patients the volume of distribution is reduced. The elimination half-life does not change.



The volume of distribution and clearance of alfuzosin are increased in renal insufficiency, with or without dialysis, owing to an increase in the free fraction. Chronic renal insufficiency even when severe (creatinine clearance between 15 and 40 mls/min) is not adversely affected by alfuzosin.



In patients with severe hepatic insufficiency, the elimination half-life is prolonged. A two-fold increase in Cmax values and a three-fold increase in the AUC is observed. Bioavailability is increased compared with healthy volunteers.



The pharmacokinetic profile of alfuzosin is not affected by chronic cardiac insufficiency.



Metabolic interactions: CYP3A4 is the principal hepatic enzyme isoform involved in the metabolism of alfuzosin (see section 4.5)
