Is mivamutide an injection or another form of medicine?

Mifamurtide injection (Mifamurtide) is an immunomodulatory drug in the form of intravenous injection. Its only approved and used form is freeze-dried powder injection, which needs to be dissolved and then infused intravenously. The drug's trade name is Mepact. Each bottle contains 20 mg of the active ingredient mivamutide. Administration needs to be diluted and prepared into an injection solution and then infused slowly. Each infusion usually takes 50 minutes to 1 hour.

The preparation form of this injection is mainly to ensure that the active ingredient of the drug-bacteria-like lipid analog (L-MTP-PE) can be stably distributed in the body and activate macrophages. Since mivamutide is a cellular immune activator and is sensitive to temperature and solvent environment, the development of oral or inhaled formulations faces great challenges. Currently, there are no alternative dosage forms on the market. The entire administration process needs to be completed in a hospital or professional infusion center, and medical staff need to monitor the patient for possible allergic reactions or fever symptoms.

According to the instructions, the recommended dosing frequency of mivamutide is twice a week during the postoperative period for 12 weeks, and then once a week for a total of 24 weeks. The entire treatment course can be up to 36 weeks, which is dynamically adjusted by the doctor based on the patient's treatment response and tolerance. Although its injection process is not as convenient as oral drugs, as a rare disease treatment drug, its therapeutic potential and survival benefits far outweigh the inconvenience caused by the complexity of administration.

In general, mivamutide is an immunotherapy drug in the form of a freeze-dried injection. It does not have oral or other dosage forms. It is currently one of the core drugs for the postoperative adjuvant treatment of high-grade osteosarcoma. Doctors should strictly follow the injection guidelines and infusion procedures when using it to ensure that the drug is fully effective and to avoid adverse reactions.
