Version July 2025
Safety: Prior to each treatment cycle, ANC should be ≥1,500/mm3, platelets ≥100,000/mm3 total bilirubin ≤ ULN, and alkaline phosphatase, ALT, AST, and CPK ≤2.5 times ULN. Administer dexamethasone 20 mg IV 30 minutes prior to each infusion to minimize hepatotoxicity.
Clinical considerations: Trabectedin is associated with a moderate emetic potential (Ref); antiemetics are recommended to prevent nausea and vomiting.
Ovarian cancer, relapsed, platinum sensitive (off-label use): IV: 1.1 mg/m2 over 3 hours every 3 weeks (in combination with doxorubicin liposomal); continue as long as clinical benefit is demonstrated or until disease progression or confirmed complete response or for 2 or more cycles beyond complete response (Ref). Delay treatment and/or reduce the trabectedin dose (to 0.9 mg/m2, then to 0.75 mg/m2) for toxicities (doxorubicin liposomal may also require modification); consider discontinuing if a second dose reduction is not tolerated (Ref).
Soft tissue sarcoma, unresectable/metastatic liposarcoma or leiomyosarcoma:
Previously treated unresectable/metastatic liposarcoma or leiomyosarcoma : IV: 1.5 mg/m2 as a continuous infusion over 24 hours once every 3 weeks; continue until disease progression or unacceptable toxicity (Ref).
Previously untreated unresectable/metastatic leiomyosarcoma (off-label use/combination) : IV: 1.1 mg/m2 over 3 hours once every 3 weeks (in combination with doxorubicin and pegfilgrastim) for a maximum of 6 combination cycles, followed by single-agent trabectedin maintenance therapy of 1.1 mg/m2 over 3 hours once every 3 weeks until disease progression or unacceptable toxicity for up to a maximum of 17 maintenance cycles (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
CrCl ≥30 mL/minute: No dosage adjustment is necessary.
CrCl <30 mL/minute or end-stage kidney disease: There is no dosage adjustment provided in the manufacturer's labeling (effects are unknown); however, no need for dosage adjustment is expected (Ref).
Hemodialysis: Hemodialysis is not expected to enhance elimination of trabectedin. No need for dosage adjustment is expected (Ref).

Concerns related to adverse effects:
• Bone marrow suppression: Anemia, neutropenia, and thrombocytopenia commonly occur; neutropenic fever and neutropenic sepsis (with fatalities) have been reported. The median onset for first occurrence of grade 3/4 neutropenia was 16 days (range: 8 days to ~10 months) and median time to recovery was 13 days (range: 3 days to ~2 months).
• Capillary leak syndrome: Capillary leak syndrome (CLS) has been reported, including serious cases resulting in death. Symptoms include hypotension, edema, and hypoalbuminemia.
• Cardiovascular events: Cardiomyopathy, including HF, decreased ejection fraction, diastolic dysfunction, or right ventricular dysfunction, has been observed; some events were grades 3 and 4. The median time to development of grades 3 and 4 cardiomyopathy was ~5 months (range: 1 to 15 months). Risk of cardiac dysfunction may be increased in patients with left ventricular ejection fraction (LVEF) below lower limit of normal, prior cumulative (lifetime) anthracycline dose ≥300 mg/m2, age ≥65, or history of cardiovascular disease. Permanently discontinue treatment for grade 3 or 4 cardiac events indicative of cardiomyopathy or for LVEF decreased below the lower limit of normal. Patients with a history of New York Heart Association class II, III, or IV heart failure or abnormal LVEF were excluded from the sarcoma study.
• Extravasation: Vesicant; ensure proper needle or catheter placement prior to and during infusion. Infuse through a central line. Avoid extravasation. Extravasation of trabectedin with subsequent tissue necrosis requiring debridement has been reported; evidence of necrosis may be delayed up to 1 week after extravasation. There are no specific antidotes for trabectedin extravasation.
• Hepatotoxicity: Hepatotoxicity (including hepatic failure) may occur with trabectedin. Grade 3 and 4 LFT elevations (AST, ALT, total bilirubin, or alkaline phosphatase) occurred in over one-third of patients. The median onset for grade 3/4 ALT or AST elevations was 29 days (range: 3 days to 11.5 months) and the median time to resolution was 13 days (range: 4 days to ~4 months); some patients experienced complete resolution. Drug-induced liver injury (ALT or AST elevation >3 times ULN, alkaline phosphatase <2 times ULN, and total bilirubin ≥2 times ULN) and ALT or AST elevations >8 times ULN have been reported. Premedication with dexamethasone (4 mg twice daily the day prior to administration) has been reported to reduce the incidence of hepatotoxicity (Grosso 2006). Patients with bilirubin above the ULN or AST or ALT >2.5 times the ULN were excluded from the sarcoma clinical trial.
• Hypersensitivity: Symptoms of hypersensitivity reactions have been reported.
• Rhabdomyolysis: Trabectedin may cause rhabdomyolysis and musculoskeletal toxicity (some fatal). Creatine phosphokinase (CPK) elevations occurred in nearly one-third of patients receiving trabectedin; grade 3 and 4 CPK elevations, some complicated by renal failure, occurred. The median time to first occurrence of grade 3 or 4 CPK elevation was 2 months (range: 1 to 11.5 months) and the median time to complete resolution was 14 days (range: 5 to 30 days).

Patients with partners who could become pregnant should use effective contraception during treatment and for 5 months after the last trabectedin dose.
Based on the mechanism of action, trabectedin may cause fetal harm if administered during pregnancy.
It is not known if trabectedin is present in breast milk. Due to the potential for serious adverse reactions in the breastfed infant, the manufacturer recommends discontinuing breastfeeding during trabectedin treatment.
CBC with differential (baseline, prior to each dose, and periodically throughout treatment cycles); total bilirubin (prior to each cycle; more frequently if clinically indicated), ALT, AST, and alkaline phosphatase (prior to each dose; more frequently if clinically indicated); renal function (baseline and during treatment); CPK (prior to each dose). Evaluate pregnancy status (prior to treatment in patients who could become pregnant). Evaluate LVEF via MUGA or echocardiogram (baseline and every 2 to 3 months until trabectedin is discontinued). Monitor for signs/symptoms of capillary leak syndrome and hypersensitivity reactions; monitor infusion site for signs/symptoms of extravasation.
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Trabectedin is a marine-derived compound (alkylating agent) which blocks the cell cycle at the G2/M phase by covalently binding to the minor DNA groove, bending the helix toward the major groove and altering DNA transcription (Garcia-Carbonero 2005). Affects activity of DNA binding proteins, transcription factors and DNA repair mechanism, leading to cell death.
