Ivosenib 250mg Tablet (Ivosidenib) – Uses, Side Effects, Dosage & Price in Pakistan

Ivosenib 250mg Tablet (Ivosidenib) is an oral targeted anticancer medicine containing ivosidenib. Ivosidenib belongs to a class of medicines called isocitrate dehydrogenase-1 (IDH1) inhibitors. It is used for selected cancers and blood disorders carrying a susceptible IDH1 mutation.

Ivosidenib has established uses in selected adults with acute myeloid leukemia (AML), relapsed or refractory myelodysplastic syndromes (MDS), and previously treated locally advanced or metastatic cholangiocarcinoma. Treatment selection depends on the disease, previous therapy, age and confirmed IDH1 mutation.

Patients looking for Ivosenib 250mg Tablet in Pakistan should use this medicine only under the supervision of an oncologist or hematologist. It is not suitable for self-treatment.

Ivosenib 250mg Tablet (Ivosidenib) Uses

Ivosidenib targets cancers with susceptible IDH1 mutations. Depending on the patient’s diagnosis and treatment history, it may be used for:

Acute Myeloid Leukemia

Ivosidenib is used in selected adults with IDH1-mutated acute myeloid leukemia (AML).

It may be used for newly diagnosed AML in certain older adults or patients whose medical conditions prevent intensive induction chemotherapy. Depending on the treatment plan, it may be prescribed alone or with azacitidine.

It is also used for adults with relapsed or refractory IDH1-mutated AML.

Myelodysplastic Syndromes

Ivosidenib has an established indication for adults with relapsed or refractory myelodysplastic syndromes (MDS) carrying a susceptible IDH1 mutation.

Cholangiocarcinoma

The medicine is also used for certain adults with previously treated, locally advanced or metastatic cholangiocarcinoma, a cancer arising from the bile ducts, when an appropriate IDH1 mutation is present.

A specialist must determine whether ivosidenib is suitable for the individual patient.

How Does Ivosidenib Work?

Some cancer cells have mutations in the IDH1 gene. These mutations lead to production of abnormal metabolites that interfere with normal cellular development and contribute to cancer growth.

Ivosidenib inhibits mutated IDH1.

By blocking abnormal IDH1 activity, the medicine can reduce the abnormal metabolic signals that help affected cancer cells survive and grow. In certain blood cancers, this can also allow abnormal immature cells to undergo further differentiation.

Because the treatment specifically targets susceptible IDH1 mutations, molecular or genetic testing is an important part of patient selection.

IDH1 Testing Before Treatment

Not every patient with AML, MDS or cholangiocarcinoma will benefit from an IDH1 inhibitor.

The tumor or blood disorder must have a susceptible IDH1 mutation identified using an appropriate diagnostic test.

Your oncology or hematology team will decide which testing is required and whether the identified mutation makes ivosidenib an appropriate treatment.

Patients should not start this medicine simply because they have one of the cancers mentioned above.

Ivosenib 250mg Tablet Dosage

The standard adult ivosidenib regimen in current prescribing information is generally 500mg orally once daily, which corresponds to two 250mg tablets when using the 250mg strength.

However, dose reduction to 250mg once daily may be required in specific situations, including certain adverse effects or drug interactions.

This means the product strength should not be confused with the prescribed daily dose.

The exact dose and duration must be determined by the treating specialist according to:

• Cancer type
• IDH1 mutation status
• Treatment response
• Side effects
• ECG results
• Other medicines being used
• Overall clinical condition

Never increase, decrease or stop treatment without instructions from your oncology team.

How to Take Ivosenib 250mg Tablet

Take Ivosenib 250mg Tablet (Ivosidenib) exactly as prescribed.

Ivosidenib is generally taken once daily at approximately the same time each day.

The tablets should be swallowed whole. Do not split, crush or chew them.

The medicine may generally be taken with or without food, but it should not be taken with a high-fat meal, because this can significantly increase exposure to the medicine.

If vomiting occurs after a dose, do not automatically take another dose. Continue according to the prescribed schedule.

Follow the missed-dose instructions provided by your specialist or pharmacist.

Ivosenib 250mg Tablet Side Effects

Side effects vary according to the disease being treated and whether ivosidenib is being used alone or with another anticancer medicine.

Reported effects can include:

• Fatigue
• Nausea
• Vomiting
• Diarrhea
• Reduced appetite
• Abdominal discomfort
• Joint pain
• Muscle pain
• Rash
• Cough
• Swelling or edema
• Changes in blood-cell counts
• Changes in liver or kidney laboratory results

Some side effects are potentially serious and require prompt medical attention.

Regular blood tests and clinical monitoring are important during treatment.

Differentiation Syndrome – Important Warning

One of the most important risks associated with ivosidenib in patients with AML or MDS is differentiation syndrome.

This condition can become life-threatening or fatal if it is not recognized and treated promptly.

Possible warning signs include:

• Fever
• Shortness of breath
• Rapid weight gain
• Swelling
• Low blood pressure
• Fluid accumulation around the lungs or heart
• Reduced oxygen levels
• Kidney problems
• Pulmonary symptoms

Patients receiving treatment for AML or MDS should understand these symptoms and seek urgent medical attention if they occur.

Healthcare professionals may use corticosteroids and supportive monitoring when differentiation syndrome is suspected.

QT Interval Prolongation

Ivosidenib can affect the electrical activity of the heart and cause QTc interval prolongation.

An ECG is therefore generally obtained before treatment, with additional ECG monitoring during therapy.

Electrolytes may also need monitoring because abnormalities in potassium, magnesium or other electrolytes can increase cardiac risk.

Tell your doctor if you experience:

• Fainting
• Severe dizziness
• Palpitations
• Irregular heartbeat
• Unexplained loss of consciousness

Certain medicines that also prolong the QT interval may need to be avoided or monitored carefully.

Guillain-Barré Syndrome

A rare but serious neurological condition called Guillain-Barré syndrome has occurred in patients receiving ivosidenib.

Contact your healthcare team immediately if you develop new:

• Muscle weakness
• Numbness
• Tingling
• Sensory changes
• Difficulty walking
• Difficulty breathing

Patients diagnosed with Guillain-Barré syndrome during treatment require specialist management.

Blood Tests and Monitoring

Patients with AML or MDS require regular laboratory monitoring.

Healthcare professionals may monitor:

• Complete blood counts
• Blood chemistry
• Kidney function
• Liver-related laboratory values
• Electrolytes
• ECG readings

Monitoring can be more frequent during the first weeks of treatment.

These tests allow doctors to identify adverse effects early and determine whether the treatment dose should be continued, interrupted or adjusted.

Drug Interactions

Ivosenib 250mg Tablet (Ivosidenib) can interact with several medicines.

Strong or moderate CYP3A4 inhibitors can increase ivosidenib exposure and may increase the risk of QT prolongation. Strong CYP3A4 inducers can reduce drug exposure and are generally avoided.

Medicines that themselves prolong the QT interval can also increase cardiac risk.

Before starting treatment, tell your specialist about all:

• Prescription medicines
• Antibiotics
• Antifungal medicines
• Heart medicines
• Supplements
• Herbal products
• Non-prescription medicines

Never start or stop another medicine without discussing potential interactions with your healthcare team.

Pregnancy and Breastfeeding

Ivosidenib may pose risks during pregnancy. Patients who are pregnant or planning pregnancy should discuss treatment with their oncology team.

Current prescribing information also advises women not to breastfeed during treatment and for a period after the final dose.

Patients should follow their specialist’s recommendations regarding pregnancy prevention, contraception and breastfeeding.
