Let's talk about the drug Verzenio (abemaciclib) for early-stage breast cancer.

When you or someone close to you is diagnosed with breast cancer, it's normal to feel overwhelmed and confused when discussing treatment options. It can be especially difficult to remember the names of new medications when doctors are talking about them. Today, we're going to talk about one such drug, abemaciclib. Let's talk simply and clearly about what this drug is, how it works, and what to be aware of when taking it.

What kind of medicine is Verzenio and how does it work?

Simply put, Verzenio is a type of drug that stops the growth of cancer cells. In medical terms, it belongs to a class of drugs called ``kinase inhibitors''.

Now imagine that inside the cells of our body there are little messengers that send messages to each other. This exchange of messages is what determines whether a cell should divide or grow. We call these messengers enzymes. In cancer, some of these messengers become overactive and keep sending the wrong message to the cancer cells, telling them to "divide quickly, grow quickly."

Verzenio targets two special messengers called `cyclin-dependent kinases 4 and 6`, or CDK4 and CDK6 for short. These two are the two that mainly help cancer cells grow and divide. Verzenio does exactly this by "blocking" the action of these two messengers. It stops that message from going to the cancer cell. Then the cancer cells lose the signal to grow and divide. This causes the cancer cells to stop growing or the size of the tumor to shrink.

What type of breast cancer is Verzenio given for?

Verzenio is not a treatment for all breast cancers. It is used specifically for cancers with specific characteristics.

They are:

• Hormone Receptor (HR)-positive: This means that these cancer cells use hormones, such as estrogen, to grow. This means that hormones are the "food" for these cancers.
• HER2-negative: Also, this type of cancer does not produce a protein called `HER2` on its surface.

Verzenio is usually prescribed for people with both of these characteristics, who have early-stage breast cancer , and who are at high risk of the cancer coming back after treatment. "Early-stage" means that the cancer has not spread beyond the breast or nearby lymph nodes.

How should I use this medicine?

Verzenio is a pill that you swallow. Be aware of these things when using it.

• Dosage: Usually prescribed to be taken twice a day.
• Time of day: Try to take your medicine at the same time every day, preferably in the morning and evening. This will help to maintain consistent levels of the medicine in your body.
• Taking with food: This pill can be taken with or without food. There is no problem about that.
• How to swallow: This is very important! The tablet must be swallowed whole . Never crush, chew, or break the tablet. If you have any broken or chipped tablets, do not use them and tell your doctor.
• If you vomit: If you vomit right after taking the medicine, skip that dose . Do not take another pill. Take your next dose at the scheduled time.

Verzenio treatment for early-stage breast cancer is usually given for up to 2 years. This means that treatment is stopped if the cancer comes back, if you have serious side effects, or if the 2-year period is up. If you have certain side effects, your doctor may lower your dose or stop taking the medicine for a while and then start it again.

How effective is Verzenio?

The success of Verzenio has been confirmed through large clinical trials. The most important of these is the clinical trial called `monarchE`.

In this study, 5,637 patients with the above-mentioned types of breast cancer were used. They were divided into two groups.

1. One group was given hormone therapy with Verzenio .

2. The other group was given hormone treatment only .

Then they followed these people for four years. They looked at how many people survived without the cancer coming back, developing a new cancer, or dying. This measure is called invasive disease-free survival (IDFS).

The results after 4 years are as follows:

• The IDFS of those who received hormone therapy with Verzenio was 85.5% .
• The IDFS of those who received hormone therapy alone was 78.6% .

How will you be monitored during treatment?

Verzenio starts working in your body from the day you start taking it. Your doctor will do various things to monitor your treatment progress.

• Scans: Usually, about 6 weeks after starting treatment, you will have a scan to see how the cancer is responding to the treatment. However, this time may be adjusted by your doctor depending on your condition.
• Blood Tests: This is very important. Verzenio can sometimes cause a decrease in the number of white blood cells in the body. This condition is called ``neutropenia.'' White blood cells are like soldiers in our body, protecting us from disease. If they are low, serious infections can occur. Therefore, your doctor will do regular blood tests to monitor the levels of white blood cells, neutrophils, and platelets. This will make sure that it is safe to continue taking the medicine.

How to manage side effects?

It's normal to have side effects with cancer treatment. The most important thing is not to panic and to report any side effects to your doctor as soon as possible . They can determine if they are serious and give you the necessary advice.

Here are the most common side effects and how to deal with them.

In addition, your doctor will also educate you about the symptoms of serious side effects, such as lung problems (cough, difficulty breathing) or blood clots (swelling, pain in the legs). If you experience any of these, it is essential to seek medical advice immediately.

What should I avoid while taking Verzenio?

When taking Verzenio, interactions may occur with certain foods and other medications. These may change how the medication works or increase side effects.
