What Is Acalabrutinib?

Acalabrutinib (pronounced [a KAL a broo ti nib]) is also known by the brand name, Calquence.

How Is Calquence Used?

Calquence has been approved by the Food and Drug Administration (FDA) to treat different types of incurable blood cancers like 慢性淋巴细胞白血病（CLL）, small lymphocytic lymphoma (SLL), or mantle cell lymphoma (MCL). Calquence can be prescribed alone or in combination with other 化疗药物, like obinutuzumab (Gazyva), depending on the severity and type of cancer.

可用配方

Calquence is only available in the form of capsules and must be administered orally. The capsules are only available in a 100 mg strength. The capsules are yellow and blue and have “ACA 100 mg” imprinted on them. Calquence is dosed twice a day, and the dose is dependent on the cancer type or severity and other factors. Verify the correct dose and frequency with your provider.

使用方法

Calquence may be taken with or without food, but it should be taken with water. When taking the capsule, swallow it whole; do not open, break, crush, chew, or allow it to dissolve in your mouth. If taken in combination with obinutuzumab (Gazyva), which is given intravenously, it is best to take Calquence at least one hour prior to the infusion.

漏服剂量

If you accidentally miss a dose, and it has been more than 3 hours, skip the missed dose and continue with the next scheduled dose. Do not take extra doses to make up for a missed dose.

贮存

将胶囊存放在室温下阴凉干燥处，并确保瓶子紧闭。

What To Avoid While Taking Calquence?

While on Calquence therapy, you must follow some precautions. Always tell your physician about any medications you are already taking. Do not take any drug or medicine (even herbals or over-the-counter medications) without prior consent from your physician or pharmacist, as they may have significant interactions with Calquence. 

Avoid any kind of immunization or vaccination without prior consent from your physician. Minimize sun exposure and use sunblock while outside. Separate taking this medication from any antacids or gastric acid-suppressing agents (like Tums, Ranitidine, or Famotidine), by at least 2 hours. Avoid taking any Proton Pump Inhibitors (PPIs) with Calquence entirely (like pantoprazole, omeprazole, etc). 

Avoid grapefruit, grapefruit juice, and any foods or supplements containing grapefruit or grapefruit juice throughout therapy as they may also interact with the medication. Avoid drinking any alcoholic beverages, especially if taking Calquence in combination with obinutuzumab. It may be necessary to discontinue Calquence 3 to 7 days before any scheduled surgeries.

Pregnancy and Calquence

Pregnancy status must be checked prior to starting chemotherapy in women of child-bearing age. Effective contraception must be used during treatment and for 1 week after the last dose. Calquence may cause fetal harm and is therefore not recommended for women who are breastfeeding during therapy. Breastfeeding should also be avoided for at least 2 weeks after the last dose.

副作用

As with any other medication, you may encounter many side effects while taking Calquence. A few things to keep in mind are:

• 您可能不会出现以下列出的所有副作用。许多人可能几乎没有副作用。
• 副作用的严重程度可能因人而异，因此不要将您的副作用与其他人的经历进行比较。
• 停止治疗后，大多数副作用都会改善。
• These side effects are easily manageable most of the time either by readjusting the dose of Calquence or using additional medications to treat the symptoms. Consult with your physician or pharmacist to explore available options.
• 不要隐瞒任何症状；当您感到任何不适时，请毫不犹豫地告诉您的医生或药剂师。 

笔记：此列表并未涵盖所有副作用。如有任何疑问，请咨询医生。 

Some of the most common side effects of Calquence are: 

恶心和呕吐

开始化疗后，您可能会感到急性或延迟性恶心和呕吐。这些症状通常在开始治疗后几小时或几天内消失。如果恶心或呕吐严重，请联系您的医生，看看他们是否可以添加 止吐药 to the regimen. Eating habits should consist of small amounts of food 4 to 6 times a day. Try to avoid eating too much at once. Maintain proper body hydration and drink fluids throughout the day. Nausea and vomiting may result in abdominal pain and can also cause a decrease in appetite, leading to weight loss. 

腹泻或腹痛

If you have watery stools more than four times a day or frequent loose, watery stools, you may have diarrhea. This is one of the most common side effects of Calquence. Abdominal pain may be associated with diarrhea. Stay hydrated and take plenty of fluids to maintain the water balance of your body. Avoid eating raw foods, fruits, vegetables, whole-grain bread, cereals, seeds, and any other foods that may exacerbate diarrhea. Foods that will help reduce diarrheal risk include boiled or baked chicken (white meat) and white rice. In rare cases, diarrhea may get severe. If that happens, consult your doctor immediately. Patients 60 years or older may experience a greater incidence of these side effects.

出血并发症

Bleeding problems may occur including bruising; black, tarry, or bloody stools; bleeding gums; blood in the urine; coughing up blood; cuts that take a long time to stop bleeding; feeling dizzy, tired, or weak; nosebleeds; pain or swelling; increased menstrual flow; throwing up blood; vomit that looks like coffee grounds; or a very bad headache. These side effects can potentially lead to serious hemorrhagic events; therefore, inform your physician if any of these bleeding complications appear. It may be necessary to discontinue Calquence 3 to 7 days before any scheduled surgeries. 

感染风险

There may be a high chance of acquiring an infection while on Calquence therapy. Infections may include fungal, bacterial (like pneumonia), or viral infections (like hepatitis B). If previously infected with hepatitis B, using Calquence may lead to the reactivation of the viral infection. In order to minimize the risk of infection, it is important to avoid crowds, unhygienic street foods, certain vaccines, etc. Early symptoms of infection may include cough, chills, fever, flu, or trouble breathing. If you acquire any infection, immediately seek advice from your physician. 

骨髓抑制

It is essential to keep up with regular blood tests, especially the complete blood count test (CBC). The CBC blood test is capable of detecting potential side effects of Calquence, including leukopenia (low white blood cells level), 血小板减少症 (low platelet count), neutropenia (low white blood cells), and anemia (low red blood cells), all of which are potential side effects from the use of Calquence.

Heart Rhythm Complications

There is a risk that Calquence may cause heart rhythm complications like atrial fibrillation or atrial flutter. Symptoms may present as shortness of breath, irregular heartbeat, chest discomfort, or dizziness. Risk is higher in patients with a history of high blood pressure or arrhythmias. 

继发性恶性肿瘤

It is possible that Calquence can give rise to a secondary type of cancer during treatment. The most common cancer is skin cancer, which is why it is essential to avoid the sun during therapy and use sunscreen while outdoors. If any new lumps or moles appear on the skin, consult your physician immediately. 

其他常见的副作用可能包括：

• Muscle tenderness or pain
• 疲劳
• 皮疹 
• 瘀伤
• Neck, joint, or bone pain

防范措施

Unless approved by your physician, Calquence is generally not recommended in: 

• Patients who have an allergy to Calquence. Allergic reactions can cause a rash over the whole body, shortness of breath, wheezing, dizziness, swelling around your mouth or eyes, fast heart rate, trouble breathing, and sweating. If you have any of these symptoms, stop using Calquence and call your doctor or get emergency help right away.
• Patients with a risk of high blood pressure or a history of 心律失常. Blood pressure should be monitored regularly.
• Patients undergoing elective surgery. Calquence may need to be discontinued 3 to 7 days before and after scheduled surgeries.
