Therapeutic indications

ADCETRIS is indicated for adult patients with previously untreated CD30+ Stage IV Hodgkin lymphoma (HL) in combination with doxorubicin, vinblastine and dacarbazine (AVD)(see sections 4.2 and 5.1).

ADCETRIS is indicated for the treatment of adult patients with CD30+ HL at increased risk of relapse or progression following autologous stem cell transplant (ASCT) (see section 5.1).

ADCETRIS is indicated for the treatment of adult patients with relapsed or refractory CD30+ Hodgkin lymphoma (HL):

  1. following ASCT, or
  2. following at least two prior therapies when ASCT or multi -agent chemotherapy is not a treatment option.

ADCETRIS is indicated for the treatment of adult patients with relapsed or refractory systemic anaplastic large cell lymphoma (sALCL).

ADCETRIS is indicated for the treatment of adult patients with CD30+ cutaneous T-cell lymphoma (CTCL) after at least 1 prior systemic therapy (see section 5.1).

Posology and method of administration

ADCETRIS should be administered under the supervision of a physician experienced in the use of anti-cancer agents.

Posology

Special patient populations

Renal and hepatic impairment

Combination therapy

Patients with renal impairment should be closely monitored for adverse events. There is no clinical trial experience using ADCETRIS in combination with chemotherapy in patients with renal impairment, where serum creatinine is ≥2.0 mg/dL and/or creatinine clearance or calculated creatinine clearance is ≤40 mL/minute. Use of ADCETRIS in combination with chemotherapy should be avoided in patients with severe renal impairment.

Patients with hepatic impairment should be closely monitored for adverse events. The recommended starting dose in patients with mild hepatic impairment is 0.9 mg/kg administered as an intravenous infusion over 30 minutes every 3 weeks. There is no clinical trial experience using ADCETRIS in combination with chemotherapy in patients with hepatic impairment, where total bilirubin is >1.5 times the upper limit of normal (ULN) (unless due to Gilbert syndrome), or aspartate aminotransferase (AST) or alanine aminotransferase (ALT) are >3 times the ULN, or >5 times the ULN if their elevation may be reasonably ascribed to the presence of HL in the liver. Use of ADCETRIS in combination with chemotherapy should be avoided in patients with moderate and severe hepatic impairment.

Monotherapy

The recommended starting dose in patients with severe renal impairment is 1.2 mg/kg administered as an intravenous infusion over 30 minutes every 3 weeks. Patients with renal impairment should be closely monitored for adverse events (see section 5.2).

The recommended starting dose in patients with hepatic impairment is 1.2 mg/kg administered as an intravenous infusion over 30 minutes every 3 weeks. Patients with hepatic impairment should be closely monitored for adverse events (see section 5.2).

Elderly

The dosing recommendations for patients aged 65 and older are the same as for adults. Currently available data are described in sections 4.8, 5.1 and 5.2.

Paediatric population

The safety and efficacy of ADCETRIS in children less than 18 years have not yet been established. Currently available data are described in sections 4.8, 5.1 and 5.2 but no recommendation on a posology can be made.

In nonclinical studies, thymus depletion has been observed (see section 5.3).

Method of administration

The recommended dose of ADCETRIS is infused over 30 minutes.

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

ADCETRIS must not be administered as an intravenous push or bolus. ADCETRIS should be administered through a dedicated intravenous line and it must not be mixed with other medicinal products (see section 6.2).

Overdose

There is no known antidote for overdose of ADCETRIS. In case of overdose, the patient should be closely monitored for adverse reactions, particularly neutropenia, and supportive treatment should be administered (see section 4.4).

Shelf life

Shelf life: 4 years.

After reconstitution/dilution, from a microbiological point of view, the product should be used immediately. However, chemical and physical in-use stability has been demonstrated for 24 hours at 2°C-8°C.

Special precautions for disposal and other handling

General precautions

Procedures for proper handling and disposal of anticancer medicines should be considered.

Proper aseptic technique throughout the handling of this medicinal product should be followed.

Instructions for reconstitution

Each single use vial must be reconstituted with 10.5 mL of water for injections to a final concentration of 5 mg/ mL. Each vial contains a 10% overfill giving 55 mg of ADCETRIS per vial and a total reconstituted volume of 11 mL.

  1. Direct the stream toward the wall of the vial and not directly at the cake or powder.
  2. Gently swirl the vial to aid dissolution. DO NOT SHAKE.
  3. The reconstituted solution in the vial is a clear to slightly opalescent, colourless solution with a final pH of 6.6.
  4. The reconstituted solution should be inspected visually for any foreign particulate matter and/or discolouration. In the event of either being observed, discard the medicinal product.

Preparation of infusion solution

The appropriate amount of reconstituted ADCETRIS must be withdrawn from the vial(s) and added to an infusion bag containing sodium chloride 9 mg/ mL (0.9%) solution for injection in order to achieve a final concentration of 0.4-1.2 mg/ mL ADCETRIS. The recommended diluent volume is 150 mL. The already reconstituted ADCETRIS can also be diluted into 5% dextrose for injection or Lactated Ringer’s for injection.

Gently invert the bag to mix the solution containing ADCETRIS. DO NOT SHAKE.

Any portion left in the vial, after withdrawal of the volume to be diluted, must be disposed of in accordance with local requirements.

Do not add other medicinal products to the prepared ADCETRIS infusion solution or intravenous infusion set. The infusion line should be flushed following administration with sodium chloride 9 mg/ mL (0.9%) solution for injection, 5% dextrose for injection, or Lactated Ringer’s for injection.

Following dilution, infuse the ADCETRIS solution immediately at the recommended infusion rate.

Total storage time of the solution from reconstitution to infusion should not exceed 24 hours.

Determining dosage amount

Calculation to determine the total ADCETRIS dose (mL) to be further diluted (see section 4.2):

ADCETRIS dose (mg/kg) x patient’s body weight (kg) / Reconstituted vial concentration (5 mg/ml) = Total ADCETRIS dose (mL) to be further diluted

Note: If patient’s weight is more than 100 kg, the dose calculation should use 100 kg. The maximal recommended dose is 180 mg.

Calculation to determine the total number of ADCETRIS vials needed:

Total ADCETRIS dose (mL) to be administered / Total volume per vial (10 mL/vial) = Number of ADCETRIS vials needed

Table 15. Sample calculations for patients receiving the recommended dose of 1.8 mg/kg of ADCETRIS for weights ranging from 60 kg to 120 kg:

Patient weight (kg) Total dose = patient weight multiplied by recommended dose [1.8 mg/kga]) Total volume to be dilutedb = total dose divided by reconstituted vial concentration [5 mg/mL]) Number of vials needed = total volume to be diluted divided by total volume per vial [10 mL/vial])
60 kg 108 mg 21.6 mL 2.16 vials
80 kg 144 mg 28.8 mL 2.88 vials
100 kg 180 mg 36 mL 3.6 vials
120 kgc 180 mgd 36 mL 3.6 vials

a For a reduced dose, use 1.2 mg/kg for the calculation.
b To be diluted in 150 mL of diluent and administered by intravenous infusion over 30 minutes every 3 weeks.
c If patient’s weight is more than 100 kg, the dose calculation should use 100 kg.
