ℹ️ 1. What Qarziba is and what it is used for
Qarziba contains dinutuximab beta, which belongs to a group of medicines called ‘monoclonal antibodies’. These are proteins, which specifically recognise and bind to other unique proteins in the body. Dinutuximab beta binds to the molecule known as disialoganglioside 2 (GD2) , which is present on cancer cells, and this activates the body’s immune system, causing it to attack the cancer cells.
Qarziba is used to treat neuroblastoma that has a high risk of coming back after a series of treatments, which include a stem cell transplantation for rebuilding the immune system. It is also used to treat neuroblastoma that has come back (relapsed) or could not be completely treated with previous therapies. Prior to the treatment of relapsed neuroblastoma, y our treating physician will stabilise any actively progressing disease by other suitable measures.
Your doctor will further decide whether the co -administration of a second medicine, interleukin-2, is necessary for the treatment of your cancer. Neuroblastoma is a type of cancer that grows from abnormal nerve cells in the body, in particular in the glands above the kidneys. It is one of the most common cancers in infancy.
It is used for patients aged 12 months and above .

🩺 Information intended for healthcare professionals only
Qarziba is restricted to hospital-use only and must be administered under the supervision of a physician experienced in the use of oncological therapies. It must be administered by a healthcare professional prepared to manage severe allergic reactions including anaphylaxis in an environment where full resuscitation services are immediately available.
Posology Treatment with dinutuximab beta consists of 5 consecutive courses, each course comprising 35 days.
The individual dose is determined based on the body surface area and should be a total of 100 mg/m2 per course.
31 Two modes of administration are possible:
- a continuous infusion over the first 10 days of each course (a total of 240 hours) at the daily dose of 10 mg/m2
- or five daily infusions of 20 mg/m2 administered over 8 hours, on the first 5 days of each course If IL-2 is combined with dinutuximab beta, it should be given as subcutaneous injections for 5 consecutive days twice during each course. First 5 -day treatment should start 7 days prior to first dinutuximab beta infusion. Second 5-day treatment with IL-2 should start concurrently with dinutuximab beta infusion (days 1 to 5 of each course). IL -2 is administered as 6×10 6 IU/m2/day, resulting in an overall dose of 60×106 IU/m2/course.
Preparation of the infusion The solution for infusion must be prepared under aseptic conditions. The solution must not be exposed to direct sunlight or heat.
The patient -specific daily dose of Qarziba is calculated based on body surface area. Qarziba should be diluted aseptically to the patient-specific concentration/dose with sodium chloride 9 mg/mL (0.9%) solution for infusion, containing 1% human albumin (e.g. 5 mL of human albumin 20% per 100 mL sodium chloride solution) .
- For continuous infusions, the solution for infusion can be prepared freshly on a daily basis, or sufficient for up to 5 days of continuous infusion. The daily dose is 10 mg/m
2. The amount of solution to be infused per day (within a treatment course of 10 consecutive days) should be 48 mL; with 240 mL for a 5 -day dose. It is recommended to prepare 50 mL solution in a 50 mL syringe, or 250 mL in an infusion bag suitable for the employed infusion pump, i.e. an overfill of 2 mL (syringe) or 10 mL (infusion bag) to allow for dead volumes of the infusion systems.
- For repeated daily infusions, the daily dose is 20 mg/m2 and the calculated dose should be diluted in 100 mL sodium chloride 9 mg/mL (0.9%) containing 1% human albumin.
Administration of the infusion The solution for infusion should be administered via a peripheral or central intravenous line. Other intravenously co-administered agents should be delivered via a separate infusion line. T he container should be inspected visually for particulates prior to administration. It is recommended that a 0.22 micrometre in -line filter is used during infusion.
For continuous infusions, any medical device suitable for infusion at a rate of 2 mL per hour can be applied , e.g. syringe infusion pumps /infusors, electronic ambulatory infusion pumps. Note that elastomeric pumps are not considered suitable in combination with in-line filters.
Storage of the diluted solution Chemical and physical in -use stability has been demonstrated for up to 48 hours at 25 °C (50 mL syringe) and for up to 7 days at 37 ºC (250 mL infusion bag), after cumulative storage in a refrigerator (2 °C – 8 °C) for 72 hours.
From a microbiological point of view, the product should be used immediately. If not used immediately, in -use storage times and conditions prior to use are the responsibility of the user and would not normally be longer than 24 hours at 2 to 8 °C, unless dilution has taken place in controlled and validated aseptic conditions.
Disposal Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
