Packaging specifications and storage conditions of icritumumab

Epcoritumab (Epcoritamab), trade name EPKINLY, is a bispecific monoclonal antibody used to treat B-cell malignancies (non-Hodgkin lymphoma). It mainly achieves targeted tumor killing by connecting CD3 on the surface of T cells and CD20 on the surface of tumor B cells. In clinical applications, the packaging specifications and storage methods of drugs are directly related to the stability of drug efficacy and drug safety, and the instruction standards must be strictly followed.

EPKINLY is a sterile, preservative-free injection that is clear to slightly opalescent, colorless to slightly yellow, and does not contain visible particles. This appearance characteristic is particularly important when the drug is being prepared for use. Any visible flocculation or discoloration should be handled with caution and avoided. Currently, there are two common single-dose glass bottles on the market: one is a small dose of 4 mg/0.8 ml, and the other is a large dose of 48 mg/0.8 ml, both of which are standard forms for clinical use. The bottle stopper is made of non-natural rubber, which reduces the risk of allergies and facilitates maintenance of sealing performance during aseptic operation.

In terms of storage,Epcoritamab needs to be stored under refrigerated conditions between 2°C and 8°C, which is the standard medical refrigerator temperature range. Medications must be kept in their original cartons until just before use to prevent light-induced degradation of the ingredients. At the same time, freezing and shaking are strictly prohibited. Freezing may cause protein structure damage, and shaking may cause protein aggregation, affecting drug stability and injection safety.

During preclinical preparation, aspiration should be performed in a sterile environment and injection should be completed within a short period of time at room temperature. If the drug is exposed to room temperature for longer than the instruction limit, it is recommended to discard it. Since this medicine does not contain preservatives, it is not recommended to use it in divided doses or store remaining medicine.

In summary,EPKINLY, as a highly active biological agent, has strict requirements for temperature, light and operating procedures. Understanding and strictly complying with its packaging specifications and storage conditions not only ensures drug efficacy, but also ensures that patients receive a safe and effective treatment experience. This is a key step that clinical personnel must master.
