Temozolomide Accord is indicated for the treatment of:

- adult patients with newly-diagnosed glioblastoma multiforme concomitantly with radiotherapy(RT) and subsequently as monotherapy treatment.

- children from the age of three years, adolescents and adult patients with malignant glioma,such as glioblastoma multiforme or anaplastic astrocytoma, showing recurrence or progressionafter standard therapy.

Temozolomide Accord should only be prescribed by physicians experienced in the oncologicaltreatment of brain tumours.

Anti-emetic therapy may be administered (see section 4.4).

Adult patients with newly-diagnosed glioblastoma multiforme

Temozolomide Accord is administered in combination with focal radiotherapy (concomitant phase)followed by up to 6 cycles of temozolomide (TMZ) monotherapy (monotherapy phase).

Concomitant phase

TMZ is administered orally at a dose of 75 mg/m2 daily for 42 days concomitant with focalradiotherapy (60 Gy administered in 30 fractions). No dose reductions are recommended, but delay ordiscontinuation of TMZ administration should be decided weekly according to haematological andnon-haematological toxicity criteria. TMZ administration can be continued throughout the 42 dayconcomitant period (up to 49 days) if all of the following conditions are met:

- absolute neutrophil count (ANC) ≥ 1.5 x 109/l

- thrombocyte count ≥ 100 x 109/l

- common toxicity criteria (CTC) non-haematological toxicity ≤ Grade 1 (except for alopecia,nausea and vomiting).

During treatment a complete blood count should be obtained weekly. TMZ administration should betemporarily interrupted or permanently discontinued during the concomitant phase according to thehaematological and non-haematological toxicity criteria as noted in Table 1.

Table 1. TMZ dosing interruption or discontinuation duringconcomitant radiotherapy and TMZ

Toxicity TMZ interruptiona TMZ discontinuation

Absolute neutrophil count ≥ 0.5 and < 1.5 x 109/l < 0.5 x 109/l

Thrombocyte count ≥ 10 and < 100 x 109/l < 10 x 109/l

CTC non-haematological toxicity(except for alopecia, nausea, vomiting) CTC Grade 2 CTC Grade 3 or 4a: Treatment with concomitant TMZ can be continued when all of the following conditions are met:

absolute neutrophil count ≥ 1.5 x 109/l; thrombocyte count ≥ 100 x 109/l; CTC non-haematological toxicity ≤ Grade 1 (except for alopecia, nausea, vomiting).

Monotherapy phase

Four weeks after completing the TMZ + RT concomitant phase, TMZ is administered for up to6 cycles of monotherapy treatment. Dose in Cycle 1 (monotherapy) is 150 mg/m2 once daily for 5 daysfollowed by 23 days without treatment. At the start of Cycle 2, the dose is escalated to 200 mg/m2 ifthe CTC non-haematological toxicity for Cycle 1 is Grade ≤ 2 (except for alopecia, nausea andvomiting), absolute neutrophil count (ANC) is ≥ 1.5 x 109/l, and the thrombocyte count is ≥ 100 x109/l. If the dose was not escalated at Cycle 2, escalation should not be done in subsequent cycles.

Once escalated, the dose remains at 200 mg/m2 per day for the first 5 days of each subsequent cycleexcept if toxicity occurs. Dose reductions and discontinuations during the monotherapy phase shouldbe applied according to Tables 2 and 3.

During treatment a complete blood count should be obtained on Day 22 (21 days after the first dose of

TMZ). The dose should be reduced or administration discontinued according to Table 3.

Adult and paediatric patients 3 years of age or older with recurrent or progressive malignant glioma:

A treatment cycle comprises 28 days. In patients previously untreated with chemotherapy, TMZ isadministered orally at a dose of 200 mg/m2 once daily for the first 5 days followed by a 23 daytreatment interruption (total of 28 days). In patients previously treated with chemotherapy, the initialdose is 150 mg/m2 once daily, to be increased in the second cycle to 200 mg/m2 once daily, for 5 daysif there is no haematological toxicity (see section 4.4)

In patients 3 years of age or older, TMZ is only to be used in recurrent or progressive malignantglioma. Experience in these children is very limited (see sections 4.4 and 5.1). The safety and efficacyof TMZ in children under the age of 3 years have not been established. No data are available.

Patients with hepatic or renal impairment

The pharmacokinetics of TMZ were comparable in patients with normal hepatic function and in thosewith mild or moderate hepatic impairment. No data are available on the administration of TMZ inpatients with severe hepatic impairment (Child's Class C) or with renal impairment. Based on thepharmacokinetic properties of TMZ, it is unlikely that dose reductions are required in patients withsevere hepatic impairment or any degree of renal impairment. However, caution should be exercisedwhen TMZ is administered in these patients.

Based on a population pharmacokinetic analysis in patients 19-78 years of age, clearance of TMZ isnot affected by age. However, elderly patients (> 70 years of age) appear to be at increased risk ofneutropenia and thrombocytopenia (see section 4.4).

Temozolomide Accord should be administered in the fasting state.

The capsules must be swallowed whole with a glass of water and must not be opened or chewed.

If vomiting occurs after the dose is administered, a second dose should not be administered that day.

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

Hypersensitivity to dacarbazine (DTIC).

Severe myelosuppression (see section 4.4).

Opportunistic infections and reactivation of infections

Opportunistic infections (such as Pneumocystis jirovecii pneumonia) and reactivation of infections(such as HBV, CMV) have been observed during the treatment with TMZ (see section 4.8).

Pneumocystis jirovecii pneumonia

Patients who received concomitant TMZ and RT in a pilot trial for the prolonged 42-day schedulewere shown to be at particular risk for developing Pneumocystis jirovecii pneumonia (PCP). Thus,prophylaxis against PCP is required for all patients receiving concomitant TMZ and RT for the 42

- day regimen (with a maximum of 49 days) regardless of lymphocyte count. If lymphopenia occurs,they are to continue the prophylaxis until recovery of lymphopenia to grade ≤ 1.

There may be a higher occurrence of PCP when TMZ is administered during a longer dosing regimen.

However, all patients receiving TMZ, particularly patients receiving steroids, should be observedclosely for the development of PCP, regardless of the regimen. Cases of fatal respiratory failure havebeen reported in patients using TMZ, in particular in combination with dexamethasone or othersteroids.

HBV

Hepatitis due to hepatitis B virus (HBV) reactivation, in some cases resulting in death, has beenreported. Experts in liver disease should be consulted before treatment is initiated in patients withpositive hepatitis B serology (including those with active disease). During treatment patients should bemonitored and managed appropriately.

Hepatic injury, including fatal hepatic failure, has been reported in patients treated with TMZ (seesection 4.8). Baseline liver function tests should be performed prior to treatment initiation. Ifabnormal, physicians should assess the benefit/risk prior to initiating temozolomide including thepotential for fatal hepatic failure. For patients on a 42 day treatment cycle liver function tests shouldbe repeated midway during this cycle. For all patients, liver function tests should be checked after eachtreatment cycle. For patients with significant liver function abnormalities, physicians should assess thebenefit/risk of continuing treatment. Liver toxicity may occur several weeks or more after the lasttreatment with temozolomide.

Meningoencephalitis herpetic

In post marketing cases, meningoencephalitis herpetic (including fatal cases) has been observed inpatients receiving TMZ in combination with radiotherapy, including cases of concomitant steroidsadministration.

Cases of myelodysplastic syndrome and secondary malignancies, including myeloid leukaemia, havealso been reported very rarely (see section 4.8).

Anti-emetic therapy

Nausea and vomiting are very commonly associated with TMZ.

Anti-emetic therapy may be administered prior to or following administration of TMZ.

Adult patients with newly-diagnosed glioblastoma multiforme

Anti-emetic prophylaxis is recommended prior to the initial dose of concomitant phase and itis strongly recommended during the monotherapy phase.

Patients with recurrent or progressive malignant glioma

Patients who have experienced severe (Grade 3 or 4) vomiting in previous treatment cycles mayrequire anti-emetic therapy.

Patients treated with TMZ may experience myelosuppression, including prolonged pancytopenia,which may result in aplastic anaemia, which in some cases has resulted in a fatal outcome. In somecases, exposure to concomitant medicinal products associated with aplastic anaemia, includingcarbamazepine, phenytoin, and sulfamethoxazole/trimethoprim, complicates assessment. Prior todosing, the following laboratory parameters must be met: ANC ≥ 1.5 x 109/l and platelet count ≥ 100 x109/l. A complete blood count should be obtained on Day 22 (21 days after the first dose) or within48 hours of that day, and weekly until ANC > 1.5 x 109/l and platelet count > 100 x 109/l. If ANC fallsto < 1.0 x 109/l or the platelet count is < 50 x 109/l during any cycle, the next cycle should be reducedone dose level (see section 4.2). Dose levels include 100 mg/m2, 150 mg/m2, and 200 mg/m2. Thelowest recommended dose is 100 mg/m2.

There is no clinical experience with use of TMZ in children under the age of 3 years. Experience inolder children and adolescents is very limited (see sections 4.2 and 5.1).

Elderly patients (> 70 years of age)

Elderly patients appear to be at increased risk of neutropenia and thrombocytopenia, compared withyounger patients. Therefore, special care should be taken when TMZ is administered in elderlypatients.

Female patients

Women of childbearing potential have to use effective contraception to avoid pregnancy while theyare receiving TMZ, and for at least 6 months following completion of treatment.

Male patients

Men being treated with TMZ should be advised not to father a child for at least 3 months afterreceiving the last dose and to seek advice on cryoconservation of sperm prior to treatment (seesection 4.6).

This medicinal product contains lactose. Patients with rare hereditary problems of galactoseintolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

This medicinal product contains less than 1 mmol sodium (23 mg) per capsule, that is to sayessentially ‘sodium-free’.

In a separate phase I study, administration of TMZ with ranitidine did not result in alterations in theextent of absorption of temozolomide or the exposure to its active metabolite monomethyltriazenoimidazole carboxamide (MTIC).

Administration of TMZ with food resulted in a 33 % decrease in Cmax and a 9 % decrease in area underthe curve (AUC).

As it cannot be excluded that the change in Cmax is clinically significant, Temozolomide Accordshould be administered without food.

Based on an analysis of population pharmacokinetics in phase II trials, co-administration ofdexamethasone, prochlorperazine, phenytoin, carbamazepine, ondansetron, H2 receptor antagonists, orphenobarbital did not alter the clearance of TMZ. Co-administration with valproic acid was associatedwith a small but statistically significant decrease in clearance of TMZ.

No studies have been conducted to determine the effect of TMZ on the metabolism or elimination ofother medicinal products. However, since TMZ does not undergo hepatic metabolism and exhibits lowprotein binding, it is unlikely that it would affect the pharmacokinetics of other medicinal products(see section 5.2).

Use of TMZ in combination with other myelosuppressive agents may increase the likelihood ofmyelosuppression.

Interaction studies have only been performed in adults.

Women of childbearing potential have to use effective contraception to avoid pregnancy while theyare receiving TMZ, and for at least 6 months following completion of treatment.

There are no data in pregnant women. In preclinical studies in rats and rabbits receiving 150 mg/m2,teratogenicity and/or foetal toxicity were demonstrated (see section 5.3). Temozolomide Accordshould not be administered to pregnant women. If use during pregnancy must be considered, thepatient should be apprised of the potential risk to the foetus.

It is not known whether TMZ is excreted in human milk; thus, breast-feeding should be discontinuedwhile receiving treatment with TMZ.

TMZ can have genotoxic effects. Therefore, men being treated with it should use effectivecontraceptive measures and be advised not to father a child for at least 3 months after receiving the lastdose and to seek advice on cryoconservation of sperm prior to treatment, because of the possibility ofirreversible infertility due to therapy with TMZ.

TMZ has minor influence on the ability to drive and use machines due to fatigue and somnolence (seesection 4.8).

Clinical trial experience

In patients treated with TMZ in clinical trials, the most common adverse reactions were nausea,vomiting, constipation, anorexia, headache, fatigue, convulsions, and rash. Most haematologicadverse reactions were reported commonly; the frequency of Grade 3-4 laboratory findings ispresented after Table 4. For patients with recurrent or progressive glioma, nausea (43 %) andvomiting (36 %) were usually Grade 1 or 2 (0 - 5 episodes of vomiting in 24 hours) and were eitherself-limiting or readily controlled with standard anti-emetic therapy. The incidence of severe nauseaand vomiting was 4 %.

Adverse reactions observed in clinical studies and reported from post-marketing use of TMZ arelisted in Table 4. These reactions are classified according to System Organ Class and frequency.

Frequency groupings are defined according to the following convention: 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); Not known (cannot be estimated from the available data). Within each frequencygrouping, undesirable effects are presented in order of decreasing seriousness.

Newly-diagnosed glioblastoma multiforme

Laboratory results

Myelosuppression (neutropenia and thrombocytopenia), which is known dose-limiting toxicity formost cytotoxic agents, including TMZ, was observed. When laboratory abnormalities and adverseevents were combined across concomitant and monotherapy treatment phases, Grade 3 or Grade 4neutrophil abnormalities including neutropenic events were observed in 8% of the patients. Grade 3 or

Grade 4 thrombocyte abnormalities, including thrombocytopenic events were observed in 14% of thepatients who received TMZ.

Recurrent or progressive malignant glioma

Laboratory results

Grade 3 or 4 thrombocytopenia and neutropenia occurred in 19 % and 17 % respectively, of patientstreated for malignant glioma. This led to hospitalisation and/or discontinuation of TMZ in 8 % and 4%, respectively. Myelosuppression was predictable (usually within the first few cycles, with the nadirbetween Day 21 and Day 28), and recovery was rapid, usually within 1-2 weeks. No evidence ofcumulative myelosuppression was observed. The presence of thrombocytopenia may increase the riskof bleeding, and the presence of neutropenia or leukopenia may increase the risk of infection.

In a population pharmacokinetics analysis of clinical trial experience there were 101 female and169 male subjects for whom nadir neutrophil counts were available and 110 female and 174 malesubjects for whom nadir platelet counts were available. There were higher rates of Grade 4neutropenia (ANC < 0.5 x 109/l), 12% vs 5%, and thrombocytopenia (< 20 x 109/l), 9% vs 3 %, inwomen vs men in the first cycle of therapy. In a 400 subject recurrent glioma data set, Grade 4neutropenia occurred in 8 % of female vs 4% of male subjects and Grade 4 thrombocytopenia in 8 %of female vs 3 % of male subjects in the first cycle of therapy. In a study of 288 subjects with newlydiagnosed glioblastoma multiforme, Grade 4 neutropenia occurred in 3 % of female vs 0% of malesubjects and Grade 4 thrombocytopenia in 1% of female vs 0% of male subjects in the first cycle oftherapy.

Oral TMZ has been studied in paediatric patients (age 3-18 years) with recurrent brainstem glioma orrecurrent high grade astrocytoma, in a regimen administered daily for 5 days every 28 days. Althoughthe data is limited, tolerance in children is expected to be the same as in adults. The safety of TMZ inchildren under the age of 3 years has not been established.

Reporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.

Doses of 500, 750, 1,000, and 1,250 mg/m2 (total dose per cycle over 5 days) have been evaluatedclinically in patients. Dose-limiting toxicity was haematological and was reported with any dose but isexpected to be more severe at higher doses. An overdose of 10,000 mg (total dose in a single cycle,over 5 days) was taken by one patient and the adverse reactions reported were pancytopenia, pyrexia,multi-organ failure and death. There are reports of patients who have taken the recommended dose formore than 5 days of treatment (up to 64 days) with adverse events reported including bone marrowsuppression, with or without infection, in some cases severe and prolonged and resulting in death. Inthe event of an overdose, haematological evaluation is needed. Supportive measures should beprovided as necessary.

5 PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Antineoplastic agents - Other alkylating agents, ATC code: L01A X03

Temozolomide is a triazene, which undergoes rapid chemical conversion at physiologic pH to theactive monomethyl triazenoimidazole carboxamide (MTIC). The cytotoxicity of MTIC is thought tobe due primarily to alkylation at the O6 position of guanine with additional alkylation also occurring atthe N7 position. Cytotoxic lesions that develop subsequently are thought to involve aberrant repair ofthe methyl adduct.

Newly diagnosed glioblastoma multiforme

A total of 573 patients were randomised to receive either TMZ + RT (n=287) or RT alone (n=286).

Patients in the TMZ + RT arm received concomitant TMZ (75 mg/m2) once daily, starting the first dayof RT until the last day of RT, for 42 days (with a maximum of 49 days). This was followed bymonotherapy TMZ (150 - 200 mg/m2) on Days 1 - 5 of every 28-day cycle for up to 6 cycles, starting4 weeks after the end of RT. Patients in the control arm received RT only. Pneumocystis jiroveciipneumonia (PCP) prophylaxis was required during RT and combined TMZ therapy.

TMZ was administered as salvage therapy in the follow-up phase in 161 patients of the 282 (57%) inthe RT alone arm, and 62 patients of the 277 (22%) in the TMZ + RT arm.

The hazard ratio (HR) for overall survival was 1.59 (95% CI for HR=1.33 -1.91) with a log-rank p <0.0001 in favour of the TMZ arm. The estimated probability of surviving 2 years or more (26% vs10%) is higher for the RT + TMZ arm. The addition of concomitant TMZ to RT, followed by TMZmonotherapy in the treatment of patients with newly diagnosed glioblastoma multiforme demonstrateda statistically significant improvement in overall survival (OS) compared with RT alone (Figure 1).

Figure 1 Kaplan-Meier curves for overall survival (intent-to-treat population)

The results from the trial were not consistent in the subgroup of patients with a poor performancestatus (WHO PS=2, n=70), where overall survival and time to progression were similar in both arms.

However, no unacceptable risks appear to be present in this patient group.

Recurrent or progressive malignant glioma

Data on clinical efficacy in patients with glioblastoma multiforme (Karnofsky performance status[KPS] ≥70), progressive or recurrent after surgery and RT, were based on two clinical trials with oral

TMZ. One was a non-comparative trial in 138 patients (29% received prior chemotherapy), and theother was a randomised active-controlled trial of TMZ vs. procarbazine in a total of 225 patients(67% received prior treatment with nitrosourea based chemotherapy). In both trials, the primaryendpoint was progression-free survival (PFS) defined by MRI scans or neurological worsening. In thenon-comparative trial, the PFS at 6 months was 19%, the median progression-free survival was2.1 months, and the median overall survival 5.4 months. The objective response rate (ORR) based on

MRI scans was 8%.

In the randomised active-controlled trial, the PFS at 6 months was significantly greater for TMZ thanfor procarbazine (21% vs. 8%, respectively - chi-square p = 0.008) with median PFS of 2.89 and1.88 months respectively (log rank p = 0.0063). The median survival was 7.34 and 5.66 months for

TMZ and procarbazine, respectively (log rank p = 0.33). At 6 months, the fraction of survivingpatients was significantly higher in the TMZ arm (60%) compared with the procarbazine arm (44%)(chi-square p = 0.019). In patients with prior chemotherapy a benefit was indicated in those with a

KPS ≥ 80.

Data on time to worsening of neurological status favoured TMZ over procarbazine as did data on timeto worsening of performance status (decrease to a KPS of < 70 or a decrease by at least 30 points). Themedian times to progression in these endpoints ranged from 0.7 to 2.1 months longer for TMZ than forprocarbazine (log rank p = < 0.01 to 0.03).

Recurrent anaplastic astrocytoma

In a multicentre, prospective phase II trial evaluating the safety and efficacy of oral TMZ in thetreatment of patients with anaplastic astrocytoma at first relapse, the 6 month PFS was 46%. Themedian PFS was 5.4 months. Median overall survival was 14.6 months. Response rate, based on thecentral reviewer assessment, was 35% (13 CR and 43 PR) for the intent-to- treat-population (ITT)n=162. In 43 patients stable disease was reported. The 6-month event-free survival for the ITTpopulation was 44% with a median event-free survival of 4.6 months, which was similar to the resultsfor the progression-free survival. For the eligible histology population, the efficacy results weresimilar. Achieving a radiological objective response or maintaining progression-free status wasstrongly associated with maintained or improved quality of life.

Oral TMZ has been studied in paediatric patients (age 3-18 years) with recurrent brainstem glioma orrecurrent high grade astrocytoma, in a regimen administered daily for 5 days every 28 days. Toleranceto TMZ is similar to adults.

TMZ is spontaneously hydrolyzed at physiologic pH primarily to the active species, 3-methyl-(triazen-1-yl)imidazole-4-carboxamide (MTIC). MTIC is spontaneously hydrolyzed to 5-amino-imidazole-4-carboxamide (AIC), a known intermediate in purine and nucleic acid biosynthesis, and tomethylhydrazine, which is believed to be the active alkylating species. The cytotoxicity of MTIC isthought to be primarily due to alkylation of DNA mainly at the O6 and N7 positions of guanine.

Relative to the AUC of TMZ, the exposure to MTIC and AIC is ~ 2.4% and 23%, respectively. Invivo, the t1/2 of MTIC was similar to that of TMZ, 1.8 hr.

After oral administration to adult patients, TMZ is absorbed rapidly, with peak concentrations reachedas early as 20 minutes post administration (mean times between 0.5 and 1.5 hours). After oraladministration of 14C-labelled TMZ, mean faecal excretion of 14C over 7 days post-dose was 0.8%indicating complete absorption.

TMZ demonstrates low protein binding (10% to 20%), and thus it is not expected to interact withhighly protein-bound substances.

PET studies in humans and preclinical data suggest that TMZ crosses rapidly the blood-brain barrierand is present in the CSF. CSF penetration was confirmed in one patient; CSF exposure based on AUCof TMZ was approximately 30% of that in plasma, which is consistent with animal data.

The half-life (t1/2) in plasma is approximately 1.8 hours. The major route of 14C elimination is renal.

Following oral administration, approximately 5% to 10% of the dose is recovered unchanged in theurine over 24 hours, and the remainder excreted as temozolomide acid, 5-aminoimidazole-4-carboxamide (AIC) or unidentified polar metabolites.

Plasma concentrations increase in a dose-related manner. Plasma clearance, volume of distribution andhalf-life are independent of dose.

Analysis of population-based pharmacokinetics of TMZ revealed that plasma TMZ clearance wasindependent of age, renal function or tobacco use. In a separate pharmacokinetic study, plasmapharmacokinetic profiles in patients with mild to moderate hepatic impairment were similar to thoseobserved in patients with normal hepatic function.

Paediatric patients had a higher AUC than adult patients; however, the maximum tolerated dose(MTD) was 1,000 mg/m2 per cycle both in children and in adults.

Single-cycle (5-day dosing, 23 days non-treatment), 3- and 6-cycle toxicity studies were conducted inrats and dogs. The primary targets of toxicity included the bone marrow, lymphoreticular system,testes, the gastrointestinal tract and, at higher doses, which were lethal to 60% to 100% of rats anddogs tested, degeneration of the retina occurred. Most of the toxicity showed evidence of reversibility,except for adverse events on the male reproductive system and retinal degeneration. However, becausethe doses implicated in retinal degeneration were in the lethal dose range, and no comparable effecthas been observed in clinical studies, this finding was not considered to have clinical relevance.

TMZ is an embryotoxic, teratogenic and genotoxic alkylating agent. TMZ is more toxic to the rat anddog than to humans, and the clinical dose approximates the minimum lethal dose in rats and dogs.

Dose-related reductions in leukocytes and platelets appear to be sensitive indicators of toxicity. Avariety of neoplasms, including mammary carcinomas, keratocanthoma of the skin and basal celladenoma were observed in the 6-cycle rat study while no tumours or pre-neoplastic changes wereevident in dog studies. Rats appear to be particularly sensitive to oncogenic effects of TMZ, with theoccurrence of first tumours within 3 months of initiating dosing. This latency period is very short evenfor an alkylating agent.

Results of the Ames/salmonella and Human Peripheral Blood Lymphocyte (HPBL) chromosomeaberration tests showed a positive mutagenicity response.
