What is Afinitor?

Afinitor is a targeted therapy used to treat several types of cancer and certain non-cancerous tumours. The active ingredient is everolimus, a drug that blocks a protein called mTOR, which stands for mechanistic target of rapamycin. This protein is a central switch that controls cell growth, cell division, and the formation of new blood vessels. In many cancers, mTOR is overactive, telling cells to multiply without stopping. Everolimus blocks that switch. It slows down the growth of cancer cells, cuts off the blood supply to tumours, and in some cases shrinks them.

Afinitor is used for advanced kidney cancer after other treatments have failed, for certain types of advanced breast cancer in postmenopausal women, for neuroendocrine tumours of the pancreas or gastrointestinal tract, for a kidney tumour called angiomyolipoma associated with tuberous sclerosis complex, and for subependymal giant cell astrocytoma, a brain tumour seen in the same genetic condition. It is not a cure. It is a long-term therapy that can keep the disease stable for months or even years. The effect is usually measured with scans every two to three months. The standard dose is 10 mg once daily. The 5 mg tablet is used for patients who need a lower dose because of side effects, or for those with liver problems, or when combined with other drugs that interact. Both strengths are taken as a single daily tablet.

Mechanism and Pharmacology

Everolimus binds to an intracellular protein called FKBP12. The drug-protein complex then inhibits mTOR, specifically a complex called mTORC1. This is the key regulatory hub that senses nutrients, growth factors, and oxygen levels, and decides whether a cell should grow and divide. By blocking mTORC1, everolimus stops the production of proteins needed for the cell cycle and reduces angiogenesis, the formation of new blood vessels that tumours need. It also directly inhibits the proliferation of cancer cells and can induce apoptosis, programmed cell death. The drug has anti-inflammatory properties and is used off-label as an immunosuppressant in organ transplantation, but Afinitor is specifically approved for oncology indications.

After oral administration, everolimus is absorbed reasonably well, with bioavailability around 30 percent. Food, especially a high-fat meal, can reduce the rate and extent of absorption. That's why the recommendation is to take the tablet consistently either always with food or always without food. Peak plasma levels are reached in about 1 to 2 hours. Everolimus is metabolized in the liver primarily by CYP3A4, and it is a substrate for the P-glycoprotein transporter. This means many drug interactions are possible. The half-life is about 30 hours, allowing for once-daily dosing. Steady-state levels are reached in about 1 to 2 weeks. The drug is eliminated mainly in the feces. Dose adjustment is required in moderate to severe liver impairment. Kidney function does not significantly affect everolimus levels, but the drug can cause kidney injury, so monitoring is necessary.

How to Use Afinitor

The standard dose for most cancers is 10 mg once daily, taken at the same time each day. The tablet should be swallowed whole with a glass of water. Do not crush or chew it. Be consistent about food: always take it with food, or always take it on an empty stomach. Taking it with a high-fat meal one day and without food the next can cause unpredictable blood levels. Your oncologist will tell you which way to take it. Once you've chosen one approach, stick to it.

If you miss a dose, take it as soon as you remember, but if it is more than 6 hours after the usual time, skip the missed dose and take the next one at the regular time. Do not double up. If you vomit after taking the tablet, do not take another one. Just continue with the next scheduled dose. Your doctor may reduce the dose from 10 mg to 5 mg daily if you develop certain side effects, especially mouth sores, infections, or lung problems. The goal is to find the highest dose you can tolerate long-term. Never change the dose on your own. Regular blood tests are required to check your kidney function, liver enzymes, blood sugar, and cholesterol, as all of these can be affected by the drug.

Side Effects of Afinitor

The most common and often the most bothersome side effect is stomatitis, which is inflammation and ulceration of the mouth. It usually begins within the first few weeks of treatment. You may notice painful sores on your tongue, cheeks, or gums. This can make eating and drinking difficult. Good oral hygiene is essential. Rinse your mouth with a non-alcoholic mouthwash or a salt and baking soda solution several times a day. Avoid spicy, acidic, or hard foods. Your doctor may prescribe a special mouthwash to reduce the pain. If the sores are severe, the dose may be reduced to 5 mg or temporarily stopped.

Infections are common because everolimus is an immunosuppressant. You may be more prone to colds, flu, sinus infections, and even unusual infections like Pneumocystis pneumonia. Watch for fever, sore throat, cough, or shortness of breath. Wash your hands often and avoid close contact with sick people. Fatigue is also very common and can be severe. Some patients describe it as a deep exhaustion that sleep doesn't fix. It may improve over time but often persists. A skin rash, often acne-like, is common and can be treated with moisturizers or topical antibiotics. Diarrhea, nausea, and loss of appetite can occur and are usually manageable with medication and diet changes.

Less common but serious side effects include pneumonitis, inflammation of the lungs. Symptoms include cough, shortness of breath, and chest pain. This is a medical emergency. Everolimus can also cause hyperglycemia, high blood sugar, and hyperlipidemia, high cholesterol and triglycerides. These are usually detected on blood tests and may require medication. Kidney damage can occur, especially in patients with pre-existing kidney disease. Liver enzyme elevations are common and usually mild, but severe hepatitis is possible. Anemia and low white blood cell counts can develop, increasing the risk of infection and fatigue. In rare cases, everolimus can cause a severe allergic reaction or a condition called angioedema, swelling of the face and throat, which is an emergency.

High-Risk Groups (Elderly, Pregnancy)

Pregnancy. Everolimus is pregnancy category D. It can cause serious harm to a developing fetus, including growth restriction and birth defects. It should not be used during pregnancy. Women of childbearing age must use effective contraception during treatment and for at least 8 weeks after the last dose. Men taking everolimus should also use contraception, as the drug may be present in semen. If pregnancy occurs, the patient must be informed of the risk. Breastfeeding is contraindicated while taking Afinitor. The drug may pass into breast milk and harm the infant.

Elderly patients can use Afinitor without dose adjustment for age alone. However, older adults are more likely to have kidney or liver problems, diabetes, and a weakened immune system. They are at higher risk of infections and side effects. Careful monitoring is essential. The 5 mg dose may be used more frequently in this population. Patients with moderate to severe liver impairment require a reduced dose, often 5 mg daily instead of 10 mg, because the drug is metabolized by the liver. Kidney function does not require dose adjustment, but serum creatinine and urine protein should be checked regularly. Patients with diabetes need close blood sugar monitoring, as everolimus can raise glucose. Those with a history of lung disease or who have had radiation to the chest are at higher risk of pneumonitis and should report any respiratory symptoms immediately.

Interaction With Activities (Driving, Alcohol)

Afinitor can cause fatigue, dizziness, and visual changes. If you feel tired or your vision is blurry, don't drive. The fatigue can come on suddenly and be severe, especially at the start of treatment. Alcohol should be limited or avoided. Alcohol can worsen liver irritation, add to the fatigue, and increase the risk of mouth sores. It can also raise blood sugar and triglycerides, which the drug already tends to do. Heavy drinking is strongly discouraged. If you drink, keep it light and tell your oncologist honestly.

Drug Interactions

Everolimus is metabolized by CYP3A4 and is a substrate for P-glycoprotein. Many drugs can change its blood levels. Strong CYP3A4 inhibitors, like ketoconazole, itraconazole, clarithromycin, and ritonavir, can increase everolimus levels and the risk of side effects. Strong CYP3A4 inducers, like rifampin, phenytoin, carbamazepine, and St. John's Wort, can lower everolimus levels and reduce its effectiveness. These combinations should be avoided if possible. If a strong inhibitor is necessary, the everolimus dose may be reduced to 5 mg. Grapefruit and grapefruit juice must be avoided entirely. They inhibit CYP3A4 and can cause blood levels to rise to dangerous heights. Everolimus itself can increase levels of drugs metabolized by CYP3A4, but this is less clinically significant. It can also increase levels of certain immunosuppressants like cyclosporine and tacrolimus if used together. Live vaccines should not be given during treatment because of the immunosuppressive effect. Inactivated vaccines may be given but may be less effective. Always tell your oncologist about every medication, supplement, and herbal product you take before starting Afinitor.

Alternative Options

For advanced kidney cancer, other targeted therapies include sunitinib (Sutent), pazopanib (Votrient), axitinib (Inlyta), and cabozantinib (Cabometyx). Immunotherapy with checkpoint inhibitors like nivolumab (Opdivo) or pembrolizumab (Keytruda) is often used. For hormone receptor-positive breast cancer, the combination of everolimus with exemestane was a standard second-line therapy, but newer CDK4/6 inhibitors like palbociclib (Ibrance), ribociclib (Kisqali), and abemaciclib (Verzenio) are now more commonly used in combination with hormone therapy. For neuroendocrine tumours, sunitinib and lanreotide (Somatuline) are alternatives. For tuberous sclerosis complex-related tumours, sirolimus is a related mTOR inhibitor. The choice depends on the specific cancer type, the patient's previous treatments, and side effect tolerance. Everolimus remains an important option because it is oral, well-studied, and effective in several rare tumours.

Frequently Asked Questions

How long does it take for Afinitor to work?
It depends on the condition. For cancer, tumour shrinkage or disease stabilization is usually assessed after 2 to 3 months with imaging scans. Some patients feel better within weeks, but the full effect on the tumour takes time. For benign tumours like those in tuberous sclerosis, shrinkage can take several months.

Why does Afinitor cause mouth sores?
The drug affects the lining of the mouth, making it more sensitive and prone to ulcers. Good oral hygiene and avoiding irritating foods help. If you get mouth sores, tell your doctor. They may prescribe a mouthwash or reduce the dose. The sores usually heal when the drug is stopped or the dose is lowered.

Will I lose my hair?
Hair thinning is not common with everolimus, but some patients notice mild thinning. It is usually not as severe as with chemotherapy. It typically grows back after treatment ends.

Can I take Afinitor with grapefruit juice?
No. Grapefruit and grapefruit juice block the enzyme that breaks down everolimus, causing blood levels to rise to dangerous levels. Avoid grapefruit entirely during treatment.

What if I get a fever while taking Afinitor?
A fever can be a sign of a serious infection because the drug suppresses your immune system. Call your oncologist immediately. Do not wait. You may need blood tests and antibiotics.
