Yondelis is indicated for the treatment of patients with advanced soft tissue sarcoma, after failure of anthracyclines and ifosfamide, or who are unsuited to receive these agents. Efficacy data are based mainly on liposarcoma and leiomyosarcoma patients.

Yondelis in combination with pegylated liposomal doxorubicin (PLD) is indicated for the treatment of patients with relapsed platinum-sensitive ovarian cancer.

Yondelis must be administered under the supervision of a physician experienced in the use of chemotherapy. Its use should be confined to qualified oncologists or other health professionals specialised in the administration of cytotoxic agents.

Posology

For the treatment of soft tissue sarcoma, the recommended dose is 1.5 mg/m² body surface area, administered as an intravenous infusion over 24 hours with a three-week interval between cycles.

For the treatment of ovarian cancer Yondelis is administered every three weeks as a 3-hour infusion at a dose of 1.1 mg/m², immediately after PLD 30 mg/m². To minimize the risk of PLD infusion reactions, the initial dose is administered at a rate no greater than 1 mg/minute. If no infusion reaction is observed, subsequent PLD infusions may be administered over a 1-hour period. (See also PLD Summary Product Characteristics for specific administration advice).

All patients must receive corticosteroids e.g. 20 mg of dexamethasone intravenously 30 minutes prior to PLD (in combination therapy) or Yondelis (in monotherapy); not only as anti-emetic prophylaxis, but also because it appears to provide hepatoprotective effects. Additional anti-emetics may be administered as needed.

The following criteria are required to allow treatment with Yondelis:

- Absolute neutrophil count (ANC) 1,500/mm³

- Platelet count 100,000/mm³

- Bilirubin upper limit of normal (ULN)

- Alkaline phosphatase 2.5 x ULN (consider hepatic isoenzymes 5-nucleotidase or GGT, if the elevation could be osseous in origin).

- Albumin 25 g/l.

- Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) 2.5 x ULN

- Creatinine clearance 30 ml/min (monotherapy), serum creatinine 1.5 mg/dl ( 132.6 μmol/l) or creatinine clearance 60 ml/min (combination therapy)

- Creatine phosphokinase (CPK) 2.5 x ULN

- Haemoglobin 9 g/dl

The same criteria as above must be met prior to re-treatment. Otherwise treatment must be delayed for up to 3 weeks until the criteria are met.

Additional monitoring of haematological parameters bilirubin, alkaline phosphatase, aminotransferases and CPK should occur weekly during the first two cycles of therapy, and at least once between treatments in subsequent cycles.

The same dose should be given for all cycles provided that no grade 3-4 toxicities are seen and that the patient fulfils the re-treatment criteria.

Dose adjustments during treatment

Prior to re-treatment, patients must fulfil the baseline criteria defined above. If any of the following events occur at any time between cycles, the dose must be reduced one level, according to table 1 below, for subsequent cycles:

- Neutropenia < 500/mm³ lasting for more than 5 days or associated with fever or infection

- Thrombocytopenia < 25,000/mm³

- Increase of bilirubin > ULN and/or alkaline phosphatase > 2.5 x ULN

- Increase of aminotransferases (AST or ALT) > 2.5 x ULN (monotherapy) or > 5 x ULN (combination therapy), which has not recovered by day 21

- Any other grade 3 or 4 adverse reactions (such as nausea, vomiting, fatigue)

Once a dose has been reduced because of toxicity, dose escalation in the subsequent cycles is not recommended. If any of these toxicities reappear in subsequent cycles in a patient exhibiting clinical benefit, the dose may be further reduced (see below). Colony stimulating factors can be administered for hematologic toxicity according to local standard practice.

Table 1 Dose modification table for Yondelis (as single agent for STS or in combination for ovarian cancer) and PLD

See the PLD SPC for more detailed information on PLD dose adjustments.

In the event that further dose reductions are necessary, treatment discontinuation should be considered.

Duration of treatment

In clinical trials, there were no pre-defined limits to the number of cycles administered. Treatment continued whilst clinical benefit was noted. Yondelis has been administered for 6 or more cycles in 29.5% and 52% of patients treated with the monotherapy and combination dose and schedule respectively. The monotherapy and combination regimens have been used for up to 38 and 21 cycles respectively. No cumulative toxicities have been observed in patients treated with multiple cycles.

Paediatric population

The safety and efficacy of trabectedin in the paediatric population have not yet been established. No data are available.

Elderly patients

No specific studies in elderly patients have been performed. Overall 20% of the 1164 patients in the integrated safety analysis of monotherapy clinical trials were over 65 years. Of the 333 patients with ovarian cancer who received trabectedin in combination with PLD, 24% were 65 years of age or older and 6% were over 75 years. No relevant differences in the safety profile were seen in this patient population. It seems that plasma clearance and distribution volume of trabectedin are not influenced by age. Therefore, dose adjustments based uniquely on age criteria are not routinely recommended.

Patients with hepatic impairment

No studies with the proposed regimen have been conducted in patients with liver dysfunction. Thus, data are not available to recommend a lower starting dose in patients with hepatic impairment. However, special caution is advised and dose adjustments may be necessary in these patients since systemic exposure is probably increased and the risk of hepatotoxicity might be increased. Patients with elevated bilirubin must not be treated with Yondelis (see section 4.4).

Patients with renal impairment

Studies including patients with renal insufficiency (creatinine clearance < 30 ml/min for the monotherapy, and < 60 ml/min for the combination regimen) have not been conducted and therefore Yondelis must not be used in this patient population (see section 4.4). Considering the pharmacokinetic characteristics of trabectedin (see section 5.2), no dose adjustments are warranted in patients with mild or moderate renal impairment.

Method of administration

Administration through a central venous line is strongly recommended (see section 6.6).

For instructions on reconstitution and dilution of the medicinal product before administration, see section 6.6.

- Hypersensitivity to trabectedin or to any of the excipients listed in section 6.1

- Concurrent serious or uncontrolled infection

- Breast-feeding (see section 4.6)

- Combination with yellow fever vaccine (see section 4.4)

Hepatic impairment

Patients must meet specific criteria on hepatic function parameters to start treatment with Yondelis. Since systemic exposure to trabectedin is probably increased due to hepatic impairment and therefore the risk of hepatotoxicity might be increased, patients with clinically relevant liver diseases, such as active chronic hepatitis, must be closely monitored and the dose adjusted if needed. Patients with elevated bilirubin must not be treated with trabectedin (see section 4.2).

Renal impairment

Creatinine clearance must be monitored prior to and during treatment. Yondelis monotherapy and combination regimens must not be used in patients with creatinine clearance < 30 ml/min and < 60 ml/min respectively (see section 4.2).

Neutropenia and thrombocytopenia

Grades 3 or 4 neutropenia and thrombocytopenia associated with Yondelis therapy have been very commonly reported. A full blood cell count including differential and platelet count must be performed at baseline, weekly for the first two cycles and then once between cycles (see section 4.2). Patients who develop fever should promptly seek medical attention. If this occurs, active supportive therapy should be started immediately.

Yondelis should not be administered to patients with baseline neutrophil counts of less than 1,500 cells/mm³ and platelets count of less than 100,000 cells/mm³. If severe neutropenia (ANC < 500 cells/mm³) lasting more than 5 days or associated with fever or infection occurs, dose reduction is recommended (see section 4.2).

Nausea and vomiting

Anti-emetic prophylaxis with corticosteroids such as dexamethasone must be administered to all patients (see section 4.2).

Rhabdomyolysis and severe CPK elevations ( > 5 x ULN)

Trabectedin must not be used in patients with CPK > 2.5 x ULN (see section 4.2). Rhabdomyolysis has been uncommonly reported, usually in association with myelotoxicity, severe liver function test abnormalities and/or renal or multiorgan failure. Therefore, CPK should be closely monitored whenever a patient may be experiencing any of these toxicities or muscle weakness or muscle pain. If rhabdomyolysis occurs, supportive measures such as parenteral hydration, urine alkalinisation and dialysis should be promptly established, as indicated. Treatment with Yondelis should be discontinued until the patient fully recovers.

Caution should be taken if medicinal products associated with rhabdomyolysis (e.g. statins), are administered concomitantly with trabectedin, since the risk of rhabdomyolysis may be increased

Liver Function Test (LFT) abnormalities

Reversible acute increases in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) have been reported in most patients. Yondelis must not be used in patients with elevated bilirubin. Patients with increases in AST, ALT and alkaline phosphatase between cycles may necessitate dose reduction (see section 4.2).

Injection site reactions

The use of central venous access is strongly recommended (see section 4.2). Patients may develop a potentially severe injection site reaction when trabectedin is administered through a peripheral venous line.

Trabectedin extravasation may cause tissue necrosis requiring debridement. There is no specific antidote for extravasation of trabectedin. Extravasation should be managed by local standard practice.

Others

Co-administration of Yondelis with potent inhibitors of the enzyme CYP3A4 should be avoided (see section 4.5). If this is not possible, close monitoring of toxicities are required and dose reductions of trabectedin should be considered.

Caution should be taken if medicinal products associated with hepatotoxicity are administered concomitantly with trabectedin, since the risk of hepatotoxicity may be increased.

Concomitant use of trabectedin with phenytoin may reduce phenytoin absorption leading to an exacerbation of convulsions. Combination of trabectedin with phenytoin or live attenuated vaccines is not recommended and with yellow fever vaccine is specifically contraindicated (see section 4.3).

The concomitant use of trabectedin with alcohol must be avoided (see section 4.5).

Men in fertile age and women of childbearing potential must use effective contraception during treatment and 3 months thereafter for women and immediately inform the treating physician if a pregnancy occurs, and 5 months after treatment for men (see section 4.6).

This medicine contains potassium, less than 1 mmol (39 mg) per vial, i.e. essentially “potassium-free”.

See also PLD Summary of Product Characteristics for more detailed information on warnings and precautions.

Effects of other substances on trabectedin

In vivo interaction studies have not been performed. Since trabectedin is metabolised mainly by CYP3A4, co-administration of substances that inhibit this isoenzyme e.g. ketoconazole, fluconazole ritonavir, clarithromycin or aprepitant could decrease metabolism and increase trabectedin concentrations. If such combinations are needed, close monitoring of toxicities is required (see section 4.4). Likewise co-administration with potent inducers of this enzyme (e.g. rifampicin, phenobarbital, Saint John's Wort) may decrease the systemic exposure to trabectedin.

Alcohol consumption must be avoided during treatment with trabectedin due to the hepatotoxicity of the medicinal product (see section 4.4).

Preclinical data have demonstrated that trabectedin is a substrate to P-gp. Concomitant administration of inhibitors of P-gp, e.g. cyclosporine and verapamil, may alter trabectedin distribution and/or elimination. The relevance of this interaction e.g. CNS toxicity has not been established. Caution should be taken in such situations.

Pregnancy

No sufficient clinical data on exposed pregnancies are available. However, based on its known mechanism of action, trabectedin may cause serious birth defects when administered during pregnancy. Trabectedin should not be used during pregnancy unless clearly necessary. If it is used during pregnancy, the patient must be informed of the potential risk to the foetus (see section 5.3) and be monitored carefully. If trabectedin is used at the end of pregnancy, potential adverse reactions should be monitored carefully in the newborns.

Breast-feeding

It is not known whether trabectedin is excreted in human milk. The excretion of trabectedin in milk has not been studied in animals. Breast-feeding is contraindicated during treatment and 3 months thereafter (see section 4.3).

Fertility

Men in fertile age and women of childbearing potential must use effective contraception during treatment and 3 months thereafter for women and immediately inform the treating physician if a pregnancy occurs (see section 5.3) and 5 months after treatment for men (see section 4.4).

Trabectedin can have genotoxic effects. Advice on conservation of sperm should be sought prior to treatment because of the possibility of irreversible infertility due to therapy with Yondelis.

If pregnancy occurs during treatment the possibility of genetic counselling should be considered. Genetic counselling is also recommended for patients wishing to have children after therapy.

No studies on the effects of the ability to drive and to use machines have been performed. However, fatigue and/or asthenia have been reported in patients receiving trabectedin. Patients who experience any of these events during therapy must not drive or operate machines.

Unless otherwise specified, the following safety profile of Yondelis is based on the evaluation in clinical trials of patients treated with the recommended treatment regimens for both indications.

Most patients treated with Yondelis can be expected to have adverse reactions of any grade (91% in monotherapy and 99% in combination therapy) and less than one third serious adverse reactions of grade 3 or 4 severity (10% in monotherapy and 25% in combination therapy). The most common adverse reactions of any severity grade were neutropenia, nausea, vomiting, increases in AST/ALT, anemia, fatigue, thrombocytopenia, anorexia and diarrhoea.

Fatal adverse reactions have occurred in 1.9% and 0.9% of patients treated with the monotherapy and combination regimens respectively. They were often the result of a combination of events including pancytopenia, febrile neutropenia, some of them with sepsis, hepatic involvement, renal or multiorgan failure and rhabdomyolysis.

Adverse reactions

The frequencies of the adverse reactions reported below are classified as very common ( 1/10), common ( 1/100 to < 1/10) and uncommon ( 1/1000 to < 1/100).

The table below displays the adverse reactions reported in 1% of patients treated with the soft tissue sarcoma recommended regimen (1.5 mg/m², 24 hour infusion every 3 weeks) according to the standard MedDRA system organ class. Both adverse reactions and laboratory values have been used to provide frequencies. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

* Derived from laboratory data

The table below provides the frequency and severity of undesirable effects considered possibly related to study drug and reported in 5% of patients with ovarian cancer randomised to receive Yondelis 1.1 mg/m²/PLD 30 mg/m² or PLD 50 mg/m² in the pivotal trial ET743-OVA-301. Both adverse reactions and laboratory values have been used. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

* Derived from laboratory data

The following reactions have been reported with a frequency below 5% in the combination arm, but are included here for their clinical relevance: neutropenic infection (< 1%), neutropenic sepsis (< 1%), pancytopenia (1.8%), bone marrow failure (1.5%), granulocytopenia (1.5%), dehydration, insomnia, peripheral sensory neuropathy, syncope, left ventricular dysfunction (< 1%), pulmonary embolism (1.2%), pulmonary edema (< 1%), cough, hepatotoxicity (< 1%), gamma-glutamyltransferase increased, bilirubin conjugated increased, musculoskeletal pain, myalgia, blood creatinine increased, oedema/peripheral oedema, catheter site reactions.

In the Yondelis+PLD arm, non-white (mainly Asian) patients had a higher incidence than white patients in grade 3 or 4 adverse reactions (96% versus 87%), and serious adverse reactions (44% versus 23% all grades). The differences were mainly observed in relation with neutropenia (93%versus 66%), anaemia (37%versus 14%) and thrombocytopenia (41%versus 19%). However, the incidences of clinical complications related to haematological toxicity such as severe infections or bleeding, or those leading to death or treatment termination, were similar in both subpopulations.

Most frequent adverse reactions

Blood and Lymphatic system disorders

Neutropenia: Neutropenia is the most common haematological toxicity. It followed a predictable pattern of rapid onset and reversibility, and was rarely associated with fever or infection. Neutrophil nadirs occurred at a median of 15 days and recovered within a week. The analysis per cycle performed in patients treated with the monotherapy regimen showed neutropenia of grade 3 and 4 in approximately 19% and 8% of cycles respectively. In this population febrile neutropenia occurred in 2% of patients and in < 1% of cycles.

Thrombocytopenia: Bleeding events associated to thrombocytopenia occurred in < 1% of patients treated with the monotherapy regimen. The analysis per cycle performed in these patients showed thrombocytopenia of grade 3 and 4 in approximately 3% and < 1% of cycles respectively.

Anaemia: Anaemia occurred in 93% and 94% of patients treated with the monotherapy and combination regimens respectively. The percentages of patients anaemic at baseline were 46% and 35% respectively. The analysis per cycle performed in patients treated with the monotherapy regimen showed anaemia of grade 3 and 4 in approximately 3% and 1% of cycles respectively.

Hepatobiliary disorders

AST/ALT increases: The median time to reach the peak values was 5 days for both AST and ALT. Most of the values had decreased to grade 1 or resolved by day 14-15 (see section 4.4). The analysis per cycle performed in patients treated with the monotherapy regimen showed grade 3 elevations of AST and ALT in 12% and 20% of cycles respectively. Grade 4 elevations of AST and ALT occurred in 1% and 2% of cycles respectively. Most transaminase elevations improved to grade 1 or to pre-retreatment levels within 15 days, and less than 2% of cycles had recovering times longer than 25 days. ALT and AST increases did not follow a cumulative pattern but showed a tendency towards less severe elevations over time.

Hyperbilirubinemia: Bilirubin peaks approximately a week after onset and resolves approximately two weeks after onset.

Liver function tests predicting severe toxicity (meeting Hy´s law) and clinical manifestations of severe hepatic injury were uncommon with a lower than 1% incidence of individual signs and symptoms including jaundice, hepatomegaly or liver pain. Mortality in the presence of hepatic injury occurred in less than 1% of patients in both regimens.

Other adverse reactions

CPK elevations and rhabdomyolysis: CPK elevations of any grade were observed in 23-26% of patients in both regimens. CPK increases in association with rhabdomyolysis were reported in less than 1% of patients.

Alopecia: Alopecia was reported in approximately 3% of patients treated with the monotherapy regimen, of which the majority was grade 1 alopecia.

Post-marketing experience

During post-marketing surveillance few cases of trabectedin extravasation with subsequent tissue necrosis requiring debridement have been reported (see section 4.4).

There is limited data on the effects of trabectedin overdose. The major anticipated toxicities are gastrointestinal, bone marrow suppression and hepatic toxicity. There is no specific antidote for trabectedin currently available. In the event of an overdose, patients should be closely monitored and symptomatic supportive care measures instituted as required.

Pharmacotherapeutic group: Antineoplastic agent, ATC code: L01CX01.

Mechanism of action

Trabectedin binds to the minor groove of DNA, bending the helix to the major groove. This binding to DNA triggers a cascade of events affecting several transcription factors, DNA binding proteins, and DNA repair pathways, resulting in perturbation of the cell cycle.

Pharmacodynamic effects

Trabectedin has been shown to exert antiproliferative in vitro and in vivo activity against a range of human tumour cell lines and experimental tumours, including malignancies such as sarcoma, breast, non-small cell lung, ovarian and melanoma.

ECG investigations

In a placebo-controlled QT/QTc study, trabectedin did not prolong the QTc interval in patients with advanced solid malignancies.

Clinical efficacy

The efficacy and safety of trabectedin in soft tissue sarcoma is based in a randomised trial in patients with locally advanced or metastatic lipo or leiomyosarcoma, whose disease had progressed or relapsed after treatment with at least anthracyclines and ifosfamide. In this trial trabectedin was administered either at 1.5 mg/m² as a 24-hour intravenous infusion every 3 weeks or at 0.58 mg/m² weekly as a 3-hour intravenous infusion for 3-weeks of a 4-week cycle. The protocol specified final time to progression (TTP) analysis showed a 26.6% reduction in the relative risk of progression for patients treated in the 24-h q3wk group [Hazard Ratio (HR)= 0.734, CI: 0.554-0.974]. Median TTP values were 3.7 months (CI: 2.1-5.4 m) in the 24-h q3wk group and 2.3 months (CI: 2.0-3.5 m) in the 3-h qwk group (p=0.0302). No significant differences were detected in overall survival (OS). Median OS with the 24-h q3wk regimen was 13.9 months (CI: 12.5-18.6) and 60.2% of patients were alive at 1 year (CI: 52.0-68.5%).

Additional efficacy data are available from 3 single-arm Phase II trials with similar populations treated with the same regimen. These trials evaluated a total of 100 patients with lipo and leiomyosarcoma and 83 patients with other types of sarcoma.

The efficacy of Yondelis/PLD combination in relapsed ovarian cancer is based on ET743-OVA-301, a randomized phase 3 study of 672 patients who received either trabectedin (1.1 mg/m²) and PLD (30 mg/m²) every 3 weeks or PLD (50 mg/m²) every 4 weeks. The primary analysis of progression free survival (PFS) was performed in 645 patients with measurable disease and assessed by independent radiology review. Treatment with the combination arm resulted in a 21% risk reduction for disease progression compared to PLD alone (HR=0.79, CI: 0.65-0.96, p=0.0190). Secondary analyses of PFS and response rate also favoured the combination arm. The results of the main efficacy analyses are summarised in the table below:

Efficacy analyses from ET743-OVA-301

* Primary efficacy analysis

^a Log rank test

^b Fisher´s test

Based on independent oncology review, patients with platinum-free interval (PFI) < 6 months (35% in Yondelis+PLD and 37% in PLD arm) had similar PFS in the two arms with both showing median PFS of 3.7 months (HR=0.89, CI: 0.67-1.20). In patients with PFI 6 months (65% in Yondelis+PLD and 63% in PLD arm), median PFS was 9.7 months in the Yondelis+PLD arm compared with 7.2 months in the PLD monotherapy arm (HR=0.66, CI: 0.52-0.85).

In the final analysis, the effect of the Yondelis+PLD combination vs. PLD alone on overall survival was more pronounced in patients with PFI 6 months (platinum-sensitive population: 27.0 vs. 24.1 months, HR=0.83, CI: 0.67-1.04) than in those with PFI < 6 months (platinum-resistant population:14.2 vs. 12.4 months, HR=0.92, CI: 0.70-1.21).

The benefit in OS with Yondelis plus PLD was not due to the effect of subsequent therapies, which were well balanced between the two treatment arms.

In the multivariate analyses including PFI, treatment effect overall survival was statistically significant favouring the Yondelis+PLD combination over PLD alone (all randomised: p=0.0285; platinum-sensitive population: p=0.0319).

No data are available comparing Yondelis+PLD to a platinum-based regimen in platinum-sensitive patients.

No statistically significant differences were found between treatment arms in global measures of Quality of Life.

This medicinal product has been authorised under “exceptional circumstances”. This means that due to the rarity of soft tissue sarcoma it has not been possible to obtain complete information on Yondelis in this indication.

The European Medicines Agency will review any new information which may become available every year and this SmPC will be updated as necessary.

Distribution

Systemic exposure after intravenous administration as a constant rate infusion is dose proportional at doses up to and including 1.8 mg/m². Trabectedin pharmacokinetic profile is consistent with a multiple-compartment disposition model.

Following intravenous administration, trabectedin demonstrates a high apparent volume of distribution, consistent with extensive tissue and plasma protein binding (94 to 98% of trabectedin in plasma is protein bound). The distribution volume at steady state of trabectedin in human subjects exceeds 5000 l.

Biotransformation

Cytochrome P450 3A4 is the major cytochrome P450 isozyme responsible for the oxidative metabolism of trabectedin at clinically relevant concentrations. Other P450 enzymes may contribute to metabolism. Trabectedin does not induce or inhibit major cytochrome P450 enzymes.

Elimination

Renal elimination of unchanged trabectedin in humans is low (less than 1%). The terminal half-life is long (population value of the terminal elimination phase: 180-hr). After a dose of radiolabelled trabectedin administered to cancer patients, faecal mean (SD) recovery of total radioactivity is 58% (17%), and urinary mean (SD) recovery is 5.8% (1.73%). Based on the population estimate for plasma clearance of trabectedin (30.9 l/h) and blood/plasma ratio (0.89), the clearance of trabectedin in whole blood is approximately 35 l/h. This value is approximately one-half the rate of human hepatic blood flow. Thus the trabectedin extraction ratio can be considered moderate. The inter-patient variability of the population estimate for plasma clearance of trabectedin was 49% and intra-patient variability was 28%.

A population pharmacokinetic analysis showed that when administered in combination with PLD, the plasma clearance of trabectedin was decreased by 31%; the plasma pharmacokinetics of PLD were not influenced by the concomitant administration of trabectedin.

Special populations

A population pharmacokinetic analysis indicated that the plasma clearance of trabectedin is not influenced by age (range 19-83 years), gender, total body weight (range: 36 to 148 kg) or body surface area (range: 0.9 to 2.8 m²). An analysis made on a limited number of patients shows that race and ethnicity are not expected to have clinically significant effects on trabectedin pharmacokinetics.

Renal impairment

There is no relevant influence of renal function measured by creatinine clearance on trabectedin pharmacokinetics within the range of values ( 30.3 ml/min) present in the patients included in the clinical studies. No data are available in patients with a creatinine clearance of less than 30.3 ml/min. The low recovery (< 9% in all studied patients) of total radioactivity in the urine after a single dose of ¹⁴C-labelled trabectedin indicates that renal impairment has little influence on the elimination of trabectedin or its metabolites.

Hepatic impairment

Although the population analysis showed no relationship between the serum liver enzymes concentrations and the plasma clearance of trabectedin, systemic exposure to trabectedin may be increased in patients with hepatic impairment; therefore close monitoring of toxicity is warranted.

Preclinical data indicate that trabectedin has limited effect on the cardiovascular, respiratory and central nervous system at exposures below the therapeutic clinical range, in terms of AUC.

The effects of trabectedin on cardiovascular and respiratory function have been investigated in vivo (anesthetised Cynomolgus monkeys). A 1 hour infusion schedule was selected to attain maximum plasma levels (C_max values) in the range of those observed in the clinic. The plasma trabectedin levels attained were 10.6 ± 5.4 (C_max), higher than those reached in patients after infusion of 1500 μg/m² for 24 (C_max of 1.8 ± 1.1 ng/ml) and similar to those reached after administration of the same dose by 3 hour infusion (C_max of 10.8 ± 3.7 ng/ml).

Myelosupression and hepatoxicity were identified as the primary toxicity for trabectedin. Findings observed included haematopoietic toxicity (severe leukopenia, anaemia, and lymphoid and bone marrow depletion) as well as increases in liver function tests, hepatocellular degeneration, intestinal epithelial necrosis, and severe local reactions at the injection site. Renal toxicological findings were detected in multi-cycle toxicity studies conducted in monkeys. These findings were secondary to severe local reaction at the administration site, and therefore uncertainly attributable to trabectedin; however, caution must be guaranteed in the interpretation of these renal findings, and treatment-related toxicity cannot be excluded.

Trabectedin is genotoxic both in vitro and in vivo. Long-term carcinogenicity studies have not been performed.

Fertility studies with trabectedin were not performed but limited histopathological changes were observed in the gonads in the repeat dose toxicity studies. Considering the nature of the compound (cytotoxic and mutagenic), it is likely to affect the reproductive capacity.

1 mg vial

Appropriate aseptic techniques must be used. Yondelis must be reconstituted and further diluted prior to infusion. When used in combination the intravenous line should be flushed well with 50 mg/ml (5%) glucose solution for infusion after administration of PLD and before administration of Yondelis. The use of any diluent other than 50 mg/ml (5%) glucose solution for infusion may cause precipitation of PLD. (See also PLD Summary Product Characteristics for specific handling instructions).

Each vial containing 1 mg of trabectedin is reconstituted with 20 ml of sterile water for injections. The solution obtained has a concentration of 0.05 mg/ml and is for single-use only.

Instructions for reconstitution

A syringe is used to inject 20 ml of sterile water for injections into the vial. Shake the vial until complete dissolution. The reconstituted solution results in a clear, colourless or slightly yellowish solution, essentially free of visible particles.

0.25 mg and 1 mg vials

This reconstituted solution contains 0.05 mg/ml of trabectedin. It requires further dilution and is for single-use only.

Instructions for dilution

The reconstituted solution should be diluted with sodium chloride 9 mg/ml (0.9%) solution for infusion or glucose 50 mg/ml (5%) solution for infusion. The required volume should be calculated as follows:

If administration is to be made through a central venous line, the appropriate amount of reconstituted solution should be withdrawn from the vial and added to an infusion bag containing 50 ml of diluent (sodium chloride 9 mg/ml (0.9%) solution for infusion or glucose 50 mg/ml (5%) solution for infusion), the concentration of trabectedin in the infusion solution being 0.030 mg/ml.

If central venous access is not feasible and a peripheral venous line has to be used, the reconstituted solution should be added to an infusion bag containing 1,000 ml of diluent (sodium chloride 9 mg/ml (0.9%) solution for infusion or glucose 50 mg/ml (5%) solution for infusion).

Parenteral solutions should be inspected visually for particles prior to administration. Once the infusion is prepared, it should be administered immediately.

Instructions for handling and disposal

Yondelis is a cytotoxic anticancer medicinal product and, as with other potentially toxic compounds, caution should be exercised during handling. Procedures for proper handling and disposal of cytotoxic medicinal products must be followed. Personnel should be trained in the correct techniques to reconstitute and dilute the medicinal product and should wear protective clothing including mask, goggles and gloves during the reconstitution and dilution. Pregnant staff must be excluded from working with this medicinal product.

Accidental contact with the skin, eyes or mucous membranes must be treated immediately with copious amounts of water.

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

No incompatibilities have been observed between Yondelis and type I glass bottles, polyvinylchloride (PVC) and polyethylene (PE) bags and tubing, polyisoprene reservoirs and titanium implantable vascular access systems.
