Pharmaceutical form

Undesirable effects

The most commonly reported adverse drug reactions associated with Ongecin treatment include: nausea with or without vomiting, raised liver transaminases (AST/ALT) and alkaline phosphatase, reported in approximately 60% of patients; proteinuria and haematuria reported in approximately 50% patients; dyspnoea reported in 10-40% of patients (highest incidence in lung cancer patients); allergic skin rashes occur in approximately 25% of patients and are associated with itching in 10% of patients.

The frequency and severity of the adverse reactions are affected by the dose, infusion rate and intervals between doses. Dose-limiting adverse reactions are reductions in thrombocyte, leucocyte and granulocyte counts.

Clinical trial data

Frequencies are defined as: Very common (> l/10), Common (> l/100 to <1/10), Uncommon (> l/1000 to <1/100), Rare (> l/10,000 to <1/1000), Very rare (<1/10,000).

The following table of undesirable effects and frequencies is based on data from clinical trials. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

Combination use in breast cancer

The frequency of grade 3 and 4 haematological toxicities, particularly neutropaenia, increases when Ongecin is used in combination with paclitaxel. However, the increase in these adverse reactions is not associated with an increased incidence of infections or haemorrhagic events. Fatigue and febrile neutropaenia occur more frequently when Ongecin is used in combination with paclitaxel. Fatigue, which is not associated with anaemia, usually resolves after the first cycle.

*Grade 4 neutropaenia lasting for more than 7 days occurred in 12.6% of patients in the combination arm and 5.0% of patients in the paclitaxel arm.

Combination use in bladder cancer

Combination use in ovarian cancer

Sensory neuropathy was also more frequent in the combination arm than with single agent carboplatin

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 Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

Preclinical safety data

In repeat-dose studies of up to 6 months in duration in mice and dogs, the principal finding was schedule and dose-dependent haematopoietic suppression which was reversible.

Ongecin is mutagenic in an in vitro mutation test and an in vivo bone marrow micronucleus test. Long term animal studies evaluating the carcinogenic potential have not been performed.

In fertility studies, Ongecin caused reversible hypospermatogenesis in male mice. No effect on the fertility of females has been detected.

Evaluation of experimental animal studies has shown reproductive toxicity e.g. birth defects and other effects on the development of the embryo or foetus, the course of gestation or peri- and postnatal development.

Therapeutic indications

Ongecin is indicated for the treatment of locally advanced or metastatic bladder cancer in combination with cisplatin.

Ongecin is indicated for treatment of patients with locally advanced or metastatic adenocarcinoma of the pancreas.

Pharmacotherapeutic group

Pharmacodynamic properties

Pharmacotherapeutic group: pyrimidine analogues ATC code: L01BC05

Cytotoxic activity in cell cultures

Ongecin shows significant cytotoxic effects against a variety of cultured murine and human tumour cells. Its action is phase-specific such that Ongecin primarily kills cells that are undergoing DNA synthesis (S-phase) and, under certain circumstances, blocks the progression of cells at the junction of the G1/S phase boundary. In vitro, the cytotoxic effect of Ongecin is dependent on both concentration and time.

Antitumoral activity in preclinical models

In animal tumour models, antitumoural activity of Ongecin is schedule-dependent. When Ongecin is administered daily, high mortality among the animals but minimal antitumoural activity is observed. If, however, Ongecin is given every third or fourth day, it can be administered in non-lethal doses with substantial antitumoural activity against a broad spectrum of mouse tumours.

Mechanism of action

Cellular metabolism and mechanism of action: Ongecin (dFdC), which is a pyrimidine antimetabolite, is metabolised intracellularly by nucleoside kinase to the active diphosphate (dFdCDP) and triphosphate (dFdCTP) nucleosides. The cytotoxic effect of Ongecin is due to inhibition of DNA synthesis by two mechanisms of action by dFdCDP and dFdCTP. First, dFdCDP inhibits ribonucleotide reductase, which is uniquely responsible for catalysing the reactions that produce deoxynucleoside triphosphates (dCTP) for DNA synthesis. Inhibition of this enzyme by dFdCDP reduces the concentration of deoxynucleosides in general and, in particular, dCTP. Second, dFdCTP competes with dCTP for incorporation into DNA (self-potentiation).

Likewise, a small amount of Ongecin may also be incorporated into RNA. Thus, the reduced intracellular concentration of dCTP potentiates the incorporation of dFdCTP into DNA. DNA polymerase epsilon lacks the ability to eliminate Ongecin and to repair the growing DNA strands. After Ongecin is incorporated into DNA, one additional nucleotide is added to the growing DNA strands. After this addition there is essentially a complete inhibition in further DNA synthesis (masked chain termination). After incorporation into DNA, Ongecin appears to induce the programmed cell death process known as apoptosis.

Clinical data

Bladder cancer

A randomised phase III study of 405 patients with advanced or metastatic urothelial transitional cell carcinoma showed no difference between the two treatment arms, Ongecin/cisplatin versus methotrexate/vinblastine/adriamycin/cisplatin (MVAC), in terms of median survival (12.8 and 14.8 months respectively, p=0.547), time to disease progression (7.4 and 7.6 months respectively, p=0.842) and response rate (49.4% and 45.7% respectively, p=0.512). However, the combination of Ongecin and cisplatin had a better toxicity profile than MVAC.

Pancreatic cancer

In a randomised phase III study of 126 patients with advanced or metastatic pancreatic cancer, Ongecin showed a statistically significant higher clinical benefit response rate than 5-fluorouracil (23.8% and 4.8% respectively, p=0.0022). Also, a statistically significant prolongation of the time to progression from 0.9 to 2.3 months (log-rank p<0.0002) and a statistically significant prolongation of median survival from 4.4 to 5.7 months (log-rank p<0.0024) was observed in patients treated with Ongecin compared to patients treated with 5-fluorouracil.

Non small cell lung cancer

In a randomised phase III study of 522 patients with inoperable, locally advanced or metastatic NSCLC, Ongecin in combination with cisplatin showed a statistically significant higher response rate than cisplatin alone (31.0% and 12.0%, respectively, p<0.0001). A statistically significant prolongation of the time to progression, from 3.7 to 5.6 months (log-rank p<0.0012) and a statistically significant prolongation of median survival from 7.6 months to 9.1 months (log-rank p<0.004) was observed in patients treated with Ongecin/cisplatin compared to patients treated with cisplatin.

In another randomised phase III study of 135 patients with stage IIIB or IV NSCLC, a combination of Ongecin and cisplatin showed a statistically significant higher response rate than a combination of cisplatin and etoposide (40.6% and 21.2%, respectively, p=0.025). A statistically significant prolongation of the time to progression, from 4.3 to 6.9 months (p=0.014) was observed in patients treated with Ongecin/cisplatin compared to patients treated with etoposide/cisplatin.

In both studies it was found that tolerability was similar in the two treatment arms.

Ovarian carcinoma

In a randomised phase III study, 356 patients with advanced epithelial ovarian carcinoma who had relapsed at least 6 months after completing platinum based therapy were randomised to therapy with Ongecin and carboplatin (GCb), or carboplatin (Cb). A statistically significant prolongation of the time to progression of disease, from 5.8 to 8.6 months (log-rank p= 0.0038) was observed in the patients treated with GCb compared to patients treated with Cb. Differences in response rate of 47.2% in the GCb arm versus 30.9% in the Cb arm (p=0.0016) and median survival 18 months (GCb) versus 17.3 (Cb) (p=0.73) favoured the GCb arm.

Breast cancer

In a randomised phase III study of 529 patients with inoperable, locally recurrent or metastatic breast cancer with relapse after adjuvant/neoadjuvant chemotherapy, Ongecin in combination with paclitaxel showed a statistically significant prolongation of time to documented disease progression from 3.98 to 6.14 months (log-rank p=0.0002) in patients treated with Ongecin/paclitaxel compared to patients treated with paclitaxel. After 377 deaths, the overall survival was 18.6 months versus 15.8 months (log rank p=0.0489, HR 0.82) in patients treated with Ongecin/paclitaxel compared to patients treated with paclitaxel and the overall response rate was 41.4% and 26.2% respectively (p= 0.0002).

Pharmacokinetic properties

The pharmacokinetics of Ongecin have been examined in 353 patients in seven studies. The 121 women and 232 men ranged in age from 29 to 79 years. Of these patients, approximately 45% had non-small cell lung cancer and 35% were diagnosed with pancreatic cancer. The following pharmacokinetic parameters were obtained for doses ranging from 500 to 2,592 mg/m2 that were infused from 0.4 to 1.2 hours.

Peak plasma concentrations (obtained within 5 minutes of the end of the infusion) were 3.2 to 45.5 µg/ml. Plasma concentrations of the parent compound following a dose of 1,000 mg/m2/30-minutes are greater than 5 µg/ml for approximately 30-minutes after the end of the infusion, and greater than 0.4 µg/ml for an additional hour.

Distribution

The volume of distribution of the central compartment was 12.4 l/m2 for women and 17.5 l/m2 for men (inter-individual variability was 91.9%). The volume of distribution of the peripheral compartment was 47.4 l/m2. The volume of the peripheral compartment was not sensitive to gender.

The plasma protein binding was considered to be negligible.

Half-life: This ranged from 42 to 94 minutes depending on age and gender. For the recommended dosing schedule, Ongecin elimination should be virtually complete within 5 to 11 hours of the start of the infusion. Ongecin does not accumulate when administered once weekly.

Metabolism

Ongecin is rapidly metabolised by cytidine deaminase in the liver, kidney, blood and other tissues. Intracellular metabolism of Ongecin produces the Ongecin mono, di and triphosphates (dFdCMP, dFdCDP and dFdCTP) of which dFdCDP and dFdCTP are considered active. These intracellular metabolites have not been detected in plasma or urine. The primary metabolite, 2'-deoxy-2', 2'-difluorouridine (dFdU), is not active and is found in plasma and urine.

Excretion

Systemic clearance ranged from 29.2 l/hr/m2 to 92.2 /hr/m2 depending on gender and age (inter-individual variability was 52.2%). Clearance for women is approximately 25% lower than the values for men. Although rapid, clearance for both men and women appears to decrease with age. For the recommended Ongecin dose of 1000 mg/m2 given as a 30-minute infusion, lower clearance values for women and men should not necessitate a decrease in the Ongecin dose. Urinary excretion: Less than 10% is excreted as unchanged drug. Renal clearance was 2 to 7 l/hr/m2.

During the week following administration, 92 to 98% of the dose of Ongecin administered is recovered, 99% in the urine, mainly in the form of dFdU and 1% of the dose is excreted in faeces.

dFdCTP kinetics

This metabolite can be found in peripheral blood mononuclear cells and the information below refers to these cells. Intracellular concentrations increase in proportion to Ongecin doses of 35-350 mg/m2/30-minutes, which give steady state concentrations of 0.4-5 µg/ml. At Ongecin plasma concentrations above 5 µg/ml, dFdCTP levels do not increase, suggesting that the formation is saturable in these cells.

Half-life of terminal elimination: 0.7-12 hours.

dFdU kinetics

Peak plasma concentrations (3-15 minutes after end of 30-minute infusion, 1000 mg/m2): 28-52 µg/ml.

Trough concentration following once weekly dosing: 0.07-1.12 µg/ml, with no apparent accumulation.

Triphasic plasma concentration versus time curve, mean half-life of terminal phase - 65 hours (range 33-84 hr).

Formation of dFdU from parent compound: 91%-98%.

Mean volume of distribution of central compartment: 18 l/m2 (range 11-22 l/m2).

Mean steady state volume of distribution (Vss): 150 l/m2 (range 96-228 l/m2).

Tissue distribution: Extensive.

Mean apparent clearance: 2.5 l/hr/m2 (range 1-4 l/hr/m2).

Urinary excretion: All.

Ongecin and paclitaxel combination therapy

Combination therapy did not alter the pharmacokinetics of either Ongecin or paclitaxel.

Ongecin and carboplatin combination therapy

When given in combination with carboplatin the pharmacokinetics of Ongecin were not altered.

Renal impairment

Mild to moderate renal insufficiency (GFR from 30 ml/min to 80 ml/min) has no consistent, significant effect on Ongecin pharmacokinetics.

Name of the medicinal product

Qualitative and quantitative composition

Special warnings and precautions for use

Prolongation of the infusion time and increased dosing frequency have been shown to increase toxicity.

Haematological toxicity

Ongecin can suppress bone marrow function as manifested by leucopoenia, thrombocytopenia and anaemia.

Patients receiving Ongecin should be monitored prior to each dose for platelet, leucocyte and granulocyte counts. Suspension or modification of therapy should be considered when drug-induced bone marrow depression is detected. However, myelosuppression is short lived and usually does not result in dose reduction and rarely in discontinuation.

Peripheral blood counts may continue to deteriorate after Ongecin administration has been stopped. In patients with impaired bone marrow function, the treatment should be started with caution.

As with other cytotoxic treatments, the risk of cumulative bone-marrow suppression must be considered when Ongecin treatment is given together with other chemotherapy.

Hepatic and renal impairment

Ongecin should be used with caution in patients with hepatic insufficiency or with impaired renal function as there is insufficient information from clinical studies to allow clear dose recommendation for this patient population.

Administration of Ongecin in patients with concurrent liver metastases or a pre-existing medical history of hepatitis, alcoholism or liver cirrhosis may lead to exacerbation of the underlying hepatic impairment.

Laboratory evaluation of renal and hepatic function (including virological tests) should be performed periodically.

Concomitant radiotherapy

Concomitant radiotherapy (given together or ≤ 7 days apart): Toxicity has been reported.

Live vaccinations

Yellow fever vaccine and other live attenuated vaccines are not recommended in patients treated with Ongecin.

Posterior reversible encephalopathy syndrome

Reports of posterior reversible encephalopathy syndrome (PRES) with potentially severe consequences have been reported in patients receiving Ongecin as single agent or in combination with other chemotherapeutic agents. Acute hypertension and seizure activity were reported in most Ongecin patients experiencing PRES, but other symptoms such as headache, lethargy, confusion and blindness could also be present. Diagnosis is optimally confirmed by magnetic resonance imaging (MRI). PRES was typically reversible with appropriate supportive measures. Ongecin should be permanently discontinued and supportive measures implemented, including blood pressure control and anti-seizure therapy, if PRES develops during therapy.

Cardiovascular

Due to the risk of cardiac and/or vascular disorders with Ongecin, particular caution must be exercised with patients presenting a history of cardiovascular events.

Capillary leak syndrome

Capillary leak syndrome has been reported in patients receiving Ongecin as single agent or in combination with other chemotherapeutic agents. The condition is usually treatable if recognised early and managed appropriately, but fatal cases have been reported. The condition involves systemic capillary hyperpermeability during which fluid and proteins from the intravascular space leak into the interstitium. The clinical features include generalised oedema, weight gain, hypoalbuminaemia, severe hypotension, acute renal impairment and pulmonary oedema. Ongecin should be discontinued and supportive measures implemented if capillary leak syndrome develops during therapy. Capillary leak syndrome can occur in later cycles and has been associated in the literature with adult respiratory distress syndrome.

Pulmonary

Pulmonary effects, sometimes severe (such as pulmonary oedema, interstitial pneumonitis or adult respiratory distress syndrome (ARDS)) have been reported in association with Ongecin therapy.

If such effects develop, consideration should be made to discontinuing Ongecin therapy. Early use of supportive care measure may help ameliorate the condition.

Renal

Haemolytic uraemic syndrome

Clinical findings consistent with the haemolytic uraemic syndrome (HUS) were rarely reported (post- marketing data) in patients receiving Ongecin. HUS is a potentially life-threatening disorder. Ongecin should be discontinued at the first signs of any evidence of microangiopathic haemolytic anaemia, such as rapidly falling haemoglobin with concomitant thrombocytopaenia, elevation of serum bilirubin, serum creatinine, blood urea nitrogen, or LDH. Renal failure may not be reversible with discontinuation of therapy and dialysis may be required.

Fertility

In fertility studies Ongecin caused hypospermatogenesis in male mice. Therefore, men being treated with Ongecin are advised not to father a child during and up to 6 months after treatment and to seek further advice regarding cryoconservation of sperm prior to treatment because of the possibility of infertility due to therapy with Ongecin.

Sodium

Ongecin 10 mg/ml contains 549.00 mg (23.88 mmol) sodium per infusion bag of 120 ml. This should be taken into consideration by patients on a controlled sodium diet.

Ongecin 10 mg/ml contains 823.50 mg (35.82 mmol) sodium per infusion bag of 180 ml. This should be taken into consideration by patients on a controlled sodium diet.

Ongecin 10 mg/ml contains 915.00 mg (39.80 mmol) sodium per infusion bag of 200 ml. This should be taken into consideration by patients on a controlled sodium diet.

Ongecin 10 mg/ml contains 1006.50 mg (43.78 mmol) sodium per infusion bag of 220 ml. This should be taken into consideration by patients on a controlled sodium diet.

Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed. However, Ongecin has been reported to cause mild to moderate somnolence, especially in combination with alcohol consumption. Patients should be cautioned against driving or operating machinery until it is established that they do not become somnolent

Dosage (Posology) and method of administration

Ongecin should only be prescribed by a physician qualified in the use of anti-cancer chemotherapy.

Infusion bags of Ongecin SUN 10 mg/ml solution for infusion allow delivery of 120 ml/ 140 ml/ 160 ml/ 170 ml/ 180 ml/ 200 ml/ 220 ml of solution (equivalent to 1200 mg/ 1400 mg/ 1600 mg/ 1700 mg/1800 mg/ 2000 mg/ 2200 mg, respectively).

If the required dose cannot be achieved with the available presentations, use of an alternative Ongecin product, including Ongecin as a concentrate or Ongecin as powder for solution for infusion, is recommended.

Posology

Bladder cancer

Combination use

The recommended dose for Ongecin is 1000 mg/m2, given by 30-minute infusion. The dose should be given on Days 1, 8 and 15 of each 28-day cycle in combination with cisplatin. Cisplatin is given at a recommended dose of 70 mg/m2 on Day 1 following Ongecin or day 2 of each 28-day cycle. This 4-week cycle is then repeated. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.

Pancreatic cancer

The recommended dose of Ongecin is 1000 mg/m2, given by 30-minute intravenous infusion. This should be repeated once weekly for up to 7 weeks followed by a week of rest. Subsequent cycles should consist of injections once weekly for 3 consecutive weeks out of every 4 weeks. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.

Non small Cell lung cancer

Monotherapy

The recommended dose of Ongecin is 1000 mg/m2, given by 30-minute intravenous infusion. This should be repeated once weekly for 3 weeks, followed by a 1-week rest period. This 4-week cycle is then repeated. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.

Combination use

The recommended dose for Ongecin is 1,250 mg/m2 body surface area given as a 30-minute intravenous infusion on Days 1 and 8 of the treatment cycle (21 days). Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.

Cisplatin has been used at doses between 75-100 mg/m2 once every 3 weeks.

Breast cancer

Combination use

Ongecin in combination with paclitaxel is recommended using paclitaxel (175 mg/m2) administered on Day 1 over approximately 3-hours as an intravenous infusion, followed by Ongecin (1250 mg/m2) as a 30-minute intravenous infusion on Days 1 and 8 of each 21-day cycle. Dose reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient. Patients should have an absolute granulocyte count of at least 1,500 (x 106/l) prior to initiation of Ongecin + paclitaxel combination.

Ovarian cancer

Combination use

Ongecin in combination with carboplatin is recommended using Ongecin 1000 mg/m2 administered on Days 1 and 8 of each 21-day cycle as a 30-minute intravenous infusion. After Ongecin, carboplatin will be given on Day 1 consistent with a target Area under curve (AUC) of 4.0 mg/ml-min. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient.

Monitoring for toxicity and dose modification due to toxicity

Dose modification due to non haematological toxicity

Periodic physical examination and checks of renal and hepatic function should be made to detect non-haematological toxicity. Dosage reduction with each cycle or within a cycle may be applied based upon the grade of toxicity experienced by the patient. In general, for severe (Grade 3 or 4) non-haematological toxicity, except nausea/vomiting, therapy with Ongecin should be withheld or decreased depending on the judgement of the treating physician. Doses should be withheld until toxicity has resolved in the opinion of the physician.

For cisplatin, carboplatin, and paclitaxel dosage adjustment in combination therapy, please refer to the corresponding Summary of Product Characteristics.

Dose modification due to haematological toxicity

Initiation of a cycle

For all indications, the patient must be monitored before each dose for platelet and granulocyte counts. Patients should have an absolute granulocyte count of at least 1,500 (x 106/l) and platelet account of 100,000 (x 106/l) prior to the initiation of a cycle.

Within a cycle

Dose modifications of Ongecin within a cycle should be performed according to the following tables:

* Treatment omitted will not be re-instated within a cycle before the absolute granulocyte count reaches at least 500 (x106/l) and the platelet count reaches 50,000 (x106/l).

* Treatment omitted will not be re-instated within a cycle. Treatment will start on day 1 of the next cycle once the absolute granulocyte count reaches at least 1,500 (x106/l) and the platelet count reaches 100,000 (x106/l).

* Treatment omitted will not be re-instated within a cycle. Treatment will start on day 1 of the next cycle once the absolute granulocyte count reaches at least 1,500 (x106/l) and the platelet count reaches 100,000 (x106/l).

Dose modifications due to haematological toxicity in subsequent cycles, for all indications

The Ongecin dose should be reduced to 75% of the original cycle initiation dose, in the case of the following haematological toxicities:

- Absolute granulocyte count < 500 x 106/l for more than 5 days

- Absolute granulocyte count < 100 x 106/l for more than 3 days

- Febrile neutropaenia

- Platelets < 25,000 x106/l

- Cycle delay of more than 1 week due to toxicity

Method of administration

Ongecin solution for infusion is for intravenous use only. The solution may be administered directly to the patient without further preparation. Ongecin solution for infusion is compatible with IV infusion set when administered over a period of 30 minutes. For single use only.

Ongecin is tolerated well during infusion and may be administered ambulant. If extravasation occurs, generally the infusion must be stopped immediately and started again in another blood vessel. The patient should be monitored carefully after the administration.

Special populations

Patients with renal or hepatic impairment

Ongecin should be used with caution in patients with hepatic or renal insufficiency as there is insufficient information from clinical studies to allow for clear dose recommendations for these patient populations.

Elderly population (> 65 years)

Ongecin has been well tolerated in patients over the age of 65. There is no evidence to suggest that dose adjustments, other than those already recommended for all patients, are necessary in the elderly.

Paediatric population (< 18 years)

Ongecin is not recommended for use in children under 18 years of age due to insufficient data on safety and efficacy.

Special precautions for disposal and other handling

Handling
