LENVIMA®

Active ingredient(s): lenvatinib (as lenvatinib mesilate)


 Consumer Medicine Information (CMI)

This leaflet provides important information about using LENVIMA. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using LENVIMA.

7. Product details

1. Why am I using LENVIMA?

LENVIMA contains the active ingredient Lenvatinib (as Lenvatinib mesilate). LENVIMA is a tyrosine kinase Inhibitor (TKI).

LENVIMA blocks the action of proteins called receptor tyrosine kinases (RTKs), which are involved in the development of new blood vessels that supply oxygen and nutrients to cells and help them to grow. These proteins can be present in high amounts in cancer cells, and by blocking their action LENVIMA may slow the rate at which the cancer cells multiply and the tumour grows and by helping to cut off the blood supply that the cancer needs.

LENVIMA is used to treat thyroid cancer in adults when radioactive iodine treatment has not helped to stop your disease.

It is also used in combination to treat patients with advanced kidney cancer (advanced renal cell carcinoma):

  • LENVIMA may be used with the medicine pembrolizumab as your first treatment when your kidney cancer has spread or cannot be removed by surgery.
  • LENVIMA may be used with the medicine everolimus after one course of treatment with another anti-cancer medicine.

It is also used to treat liver cancer (hepatocellular carcinoma).

It is also used (along with another medicine called pembrolizumab) to treat a kind of uterine cancer called endometrial carcinoma, if laboratory tests show the cancer is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) and other treatments have not helped stop the disease.

2. What should I know before I use LENVIMA?

Before taking LENVIMA, your doctor may carry out some blood tests, for example to check your blood pressure and your liver or kidney function and to see if you have low levels of salt and high levels of thyroid stimulating hormone in your blood. Your doctor will discuss the results of these tests with you and decide whether you can be given LENVIMA. You may need to have additional treatment with other medicines, to take a lower dose of LENVIMA, or to take extra care due to an increased risk of side effects.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Warnings

Do not use LENVIMA if:

  • you are allergic to Lenvatinib (as Lenvatinib mesilate), or any of the ingredients listed at the end of this leaflet.
  • you are breast-feeding.
  • Always check the ingredients to make sure you can use this medicine.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin

Check with your doctor if you:

  • Have high blood pressure
  • are a woman able to become pregnant
  • Have a history of heart problems or stroke
  • Are over 75 years of age
  • Have had recent surgery or radiotherapy
  • Have liver or kidney problems
  • have had recent surgery or radiotherapy
  • take any medicines for any other condition
  • need to have a surgical procedure. Your doctor may consider stopping LENVIMA if you will be undergoing a major surgical procedure as LENVIMA may affect wound healing. LENVIMA may be restarted once adequate wound healing is established.
  • have or have had pain in the mouth, teeth and/or jaw, swelling or sores inside the mouth, numbness or a feeling of heaviness in the jaw, or loosening of a tooth. You may be advised to have a dental check-up before starting LENVIMA as bone damage in the jaw (osteonecrosis) has been reported in patients treated with LENVIMA. If you need to undergo an invasive dental treatment or dental surgery, tell your dentist that you are being treated with LENVIMA, particularly when you are also receiving or have received injections of bisphosphonates (used to treat or prevent bone disorders).
  • are receiving or have received some medicines used to treat osteoporosis (antiresorptive medicines) or cancer medicines which alter formation of blood vessels (so called angiogenesis inhibitors), as the risk of bone damage in the jaw may be increased.
  • belong to an ethnic group other than white or Asian
  • weigh less than 60 kg
  • have a history of abnormal passageways (known as a fistula) between different organs in the body or from an organ to the skin
  • If you have or have had an aneurysm (enlargement and weakening of a blood vessel wall) or a tear in a blood vessel wall.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

LENVIMA is not recommended in pregnancy.

You must use a highly effective method of contraception to avoid becoming pregnant while you are taking LENVIMA. You should continue doing this for one month after stopping treatment.

Do not breast-feed if you are taking LENVIMA. This is because the medicine may pass into breast milk and may seriously harm your breastfed baby.

Children and Teenagers

Do not give this medicine to anyone under the age of 18 years. LENVIMA is not recommended for use in children and teenagers. The effects of LENVIMA in people younger than 18 years old are not known.

Safety and effectiveness in children younger than 18 years have not been established.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with LENVIMA and affect how it works.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect LENVIMA.

When to take LENVIMA

  • LENVIMA should be taken at about the same time each day.
  • Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How to take LENVIMA

Swallow the capsules whole with a full glass of water. If unable to swallow the capsule whole, then place the capsule in a glass of about 25 mL of water or apple juice without breaking or crushing the capsules.

Do not mix more than one medicine in the glass at the same time.

Let the capsules disintegrate for about 10 minutes and then gently stir for at least 3 minutes to dissolve the capsule shells. Then swallow the suspension. After drinking, add the same amount of water or apple juice to the glass and gently swirl it around and swallow the mixture.

The person preparing the suspension should thoroughly wash their hands before and after the suspension is prepared and the dose taken.

You can take LENVIMA with or without food.

Do not chew, crush or split the capsules. To ensure you get the entire dose, the capsules should be swallowed whole without chewing or crushing.

Caregivers should not open capsules to avoid exposure to the contents of the capsule.

If you forget to use LENVIMA

LENVIMA should be used regularly at the same time each day.

If it is 12 hours or more until your next dose, take the missed dose as soon as you remember. Then take the next dose at the normal time. If it is less than 12 hours until your next dose, skip the missed dose. Then take your next dose at the normal time.

Do not take a double dose to make up for the dose that you missed.

This may increase the chance of you getting an unwanted side effect.

4.9 Overdose

For information on the management of overdose, contact the Poison Information Centre on 131126 (Australia).
There have been reports of overdose with Lenvima including a single administration of 144 mg, 6 times the recommended daily dose. These cases were associated with adverse reactions consistent with the known safety profile of Lenvima, or were without adverse reactions. Death due to multiorgan dysfunction occurred in a patient who received a single dose of Lenvima 120 mg orally. There is no specific antidote for overdose with Lenvima, due to the high plasma protein binding, lenvatinib is not expected to be dialyzable. In case of suspected overdose, Lenvima should be withheld and appropriate supportive care given as required.

5 Pharmacological Properties

5.3 Preclinical Safety Data

In the repeated-dose toxicity studies (up to 39 weeks), lenvatinib caused toxicologic changes in various organs and tissues related to the expected pharmacologic effects of lenvatinib including glomerulopathy, testicular hypocellularity, ovarian follicular atresia, gastrointestinal changes, bone changes, changes to the adrenals (rats and dogs), and arterial (arterial fibrinoid necrosis, medial degeneration, or haemorrhage) lesions in rats, dogs, and cynomolgus monkeys. Elevated transaminase levels asociated with signs of hepatotoxicity, were also observed in rats, dogs and monkeys. Reversibility of the toxicologic changes was observed at the end of a 4-week recovery period in all animal species investigated.
Genotoxicity. Lenvatinib was not mutagenic in the in vitro Ames and mouse lymphoma tests and not clastogenic in an in vivo micronucleus assay in rats. These studies indicate a low genotoxic potential for Lenvima.
Carcinogenicity. Carcinogenicity studies have not been conducted with Lenvima.
Reproductive and developmental toxicity. No specific studies with lenvatinib have been conducted in animals to evaluate the effect on fertility. However, testicular (hypocellularity of the seminiferous epithelium) and ovarian changes (follicular atresia) were observed in repeated-dose toxicity studies in animals at exposures 11 to 15 times (rat) or 0.6 to 7 times (monkey) the anticipated clinical exposure (based on AUC) at the maximum tolerated human dose. These findings were reversible at the end of a 4-week recovery period.
Administration of lenvatinib during organogenesis resulted in embryolethality and teratogenicity in rats (foetal external and skeletal anomalies) at exposures below the clinical exposure (based on AUC) at the maximum tolerated human dose, and rabbits (foetal external, visceral or skeletal anomalies) based on body surface area; mg/m2 at the maximum tolerated human dose. These findings indicate that lenvatinib has a teratogenic potential, likely related to the pharmacologic activity of lenvatinib as an antiangiogenic agent. Lenvatinib and its metabolites are excreted in rat milk.
Juvenile animal toxicity studies. Mortality was the dose-limiting toxicity in juvenile rats in which dosing was initiated on postnatal day (PND) 7 or PND21 and was observed at exposures that were respectively 125- or 12-fold lower compared with the exposure at which mortality was observed in adult rats, suggesting an increasing sensitivity to toxicity with decreasing age. Therefore, mortality may be attributed to complications related to primary duodenal lesions with possible contribution from additional toxicities in immature target organs.
The toxicity of lenvatinib was more prominent in younger rats (dosing initiated on PND7) compared with those with dosing initiated on PND21 and mortality and some toxicities were observed earlier in the juvenile rats at 10 mg/kg compared with adult rats administered the same dose level. Growth retardation, secondary delay of physical development, and lesions attributable to pharmacologic effects (incisors, femur [epiphyseal growth plate], kidneys, adrenals, and duodenum) were also observed in juvenile rats.
