Seleniso latest instruction manual

Detailed description of indications:

Selinesol, as an innovative therapeutic drug, is mainly used in the clinical treatment of specific types of cancer, especially in the fields of multiple myeloma and diffuse large B cell lymphoma (DLBCL). Seleniso has unique adaptability to the following situations:

1.In the treatment of multiple myeloma, selinesol forms a synergistic treatment strategy with bortezomib and dexamethasone. For adult patients who have experienced at least one prior therapy, selinexol 100 mg daily is recommended as an oral dose on the first day of each week only. The dose of bortezomib is usually determined based on the patient's body surface area. It is generally recommended to use 1.3 mg per square meter, subcutaneously injected once a week for four consecutive weeks and then one week off. At the same time, dexamethasone was administered orally at 20 mg on the first and second days of each week.

2.For relapsed or refractory multiple myeloma, seliniso can be used together with dexamethasone in experienced adult patients. These patients were required to meet specific criteria, namely, have received at least four treatments and had no significant response to at least two proteasome inhibitors, two immunomodulators, and an anti-CD38 monoclonal antibody. In this case, the combined regimen of selinesol and dexamethasone was adjusted to 80 mg selinesol orally and 20 mg dexamethasone twice daily on the first and third days of the week.

3.In the treatment of DLBCL, especially in relapsed or refractory cases caused by follicular lymphoma, selinesol is included in the accelerated approval process for adult patients who have received at least two previous systemic therapies. The treatment method is on the first and third days of each week. Patients need to take 60 mg of selinexol orally on the first and third days of each week in order to improve the therapeutic effect.

Mechanism of action:

Selinesol's mechanism of action is based on its unique inhibition of the nuclear export proteinXPO1, which prevents the transfer of key proteins in the nucleus to the cytoplasm. Blocking this process leads to changes in the distribution of key proteins in tumor cells, which in turn interferes with multiple complex signaling pathways, ultimately achieving the purpose of inhibiting tumor cell growth. Selinisol exhibits significant anti-cancer activity by promoting cell apoptosis, inhibiting cell proliferation, and effectively preventing transcription factors from leaving the nuclear membrane, thereby comprehensively curbing the spread and progression of various malignant tumors.

Medication guidance and side effect management:

When using selinesol, patients need to pay attention to the use of other drugs. For example, in multiple myeloma treatment, make sure to avoid drinking alcohol and smoking on the first day of the week to ensure maximum effectiveness of the medication. At the same time, if signs of a low neutrophil count appear, supportive therapy such as granulocyte colony-stimulating factor may be needed, as well as close monitoring to prevent and manage possible infections.

Side effects include:

1. Blood system problems: Selinisol may cause bone marrow suppression, manifested by a decrease in the number of hemoglobin, platelets and white blood cells, posing a potential threat to the patient's hematopoietic function and immune system.

2.Digestive system reactions: Patients may experience discomfort such as nausea, vomiting, constipation and diarrhea, which may affect appetite and nutrient absorption, thereby triggering weight loss.

3.Systemic reactions: Long-term use of selinesol may cause symptoms such as fatigue, weight loss, and elevated body temperature, which will affect the patient's quality of life and daily activities.

4.Allergic reaction: Some patients may have an allergic reaction to selinexol, which may cause rash and itching. In severe cases, it may cause laryngeal edema and dyspnea, which needs to be identified and treated in time.

When using selinesol, be sure to follow your doctor's recommendations and warnings, especially for pregnant and lactating women, who should be cautious to ensure the safety and effectiveness of the drug.
