What is Copiktra (duvelisib), and how does it work?
Generic drug: duvelisib
Brand name: Copiktra
Copiktra (duvelisib) is a prescription medicine used to treat adults with:
- Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL) who have received at least 2 prior therapies and they did not work or are no longer working.
- Follicular Lymphoma (FL) who have received at least 2 prior therapies and they did not work or are no longer working.
It is not known if Copiktra is safe and effective in children less than 18 years of age.
What are the side effects of Copiktra?
Copiktra may cause serious side effects, including:
- Elevated liver enzymes. Copiktra may cause abnormalities in liver blood tests. Your healthcare provider should do blood tests during your treatment with Copiktra to check for liver problems. Tell your healthcare provider right away if you get any symptoms of liver problems, including yellowing of your skin or the white part of your eyes (jaundice), pain in the abdominal region, bruising or bleeding more easily than normal.
- Low white blood cell count (neutropenia). Neutropenia is common with Copiktra treatment and can sometimes be serious. Your healthcare provider should check your blood counts regularly during treatment with Copiktra. Tell your healthcare provider right away if you have a fever or any signs of infection during treatment with Copiktra.
Common side effects of Copiktra include:
These are not all the possible side effects of Copiktra.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
- Fatal and/or serious infections occurred in 31% of Copiktra-treated patients. Monitor for signs and symptoms of infection. Withhold Copiktra if infection is suspected.
- Fatal and/or serious diarrhea or colitis occurred in 18% of Copiktra-treated patients. Monitor for the development of severe diarrhea or colitis. Withhold Copiktra.
- Fatal and/or serious cutaneous reactions occurred in 5% of Copiktra-treated patients. Withhold Copiktra.
- Fatal and/or serious pneumonitis occurred in 5% of Copiktra-treated patients. Monitor for pulmonary symptoms and interstitial infiltrates. Withhold Copiktra.
What is the dosage for Copiktra?
- The recommended dose of Copiktra is 25 mg administered as oral capsules twice daily (BID) with or without food. A cycle consists of 28 days. The capsules should be swallowed whole. Advise patients not to open, break, or chew the capsules.
- Advise patients that if a dose is missed by fewer than 6 hours, to take the missed dose right away and take the next dose as usual. If a dose is missed by more than 6 hours, advise patients to wait and take the next dose at the usual time.
- Provide prophylaxis for Pneumocystis jirovecii (PJP) during treatment with Copiktra. Following completion of Copiktra treatment, continue PJP prophylaxis until the absolute CD4+ T cell count is greater than 200 cells/μL.
- Withhold Copiktra in patients with suspected PJP of any grade, and discontinue if PJP is confirmed.
- Consider prophylactic antivirals during Copiktra treatment to prevent cytomegalovirus (CMV) infection including CMV reactivation.

What drugs interact with Copiktra?
Effects Of Other Drugs On Copiktra
- Co-administration with a strong CYP3A inducer decreases duvelisib area under the curve (AUC), which may reduce Copiktra efficacy.
- Avoid co-administration of Copiktra with strong CYP3A4 inducers.
- Co-administration with a strong CYP3A inhibitor increases duvelisib AUC, which may increase the risk of Copiktra toxicities.
- Reduce Copiktra dose to 15 mg BID when co-administered with a strong CYP3A4 inhibitor.
Effects Of Copiktra On Other Drugs
- Co-administration with Copiktra increases AUC of a sensitive CYP3A4 substrate which may increase the risk of toxicities of these drugs.
- Consider reducing the dose of the sensitive CYP3A4 substrate and monitor for signs of toxicities of the co-administered sensitive CYP3A substrate.
Is Copiktra safe to use while pregnant or breastfeeding?
- Based on findings from animal studies and the mechanism of action, Copiktra can cause fetal harm when administered to a pregnant woman.
- There are no data on the presence of duvelisib and/or its metabolites in human milk, the effects on the breastfed child, or on milk production.
- Because of the potential for serious adverse reactions from duvelisib in a breastfed child, lactating women should not breastfeed while taking Copiktra and for at least 1 month after the last dose.

Related Disease Conditions
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Leukemia is a type of cancer of the blood cells in which the growth and development of the blood cells are abnormal. Strictly speaking, leukemia should refer only to cancer of the white blood cells (the leukocytes) but in practice it can apply to malignancy of any cellular element in the blood or bone marrow, as in red cell leukemia (erythroleukemia).
What Is the Life Expectancy of a Person With Leukemia?
Leukemia is a group of cancers of the blood affecting the white blood cells. White blood cells are the infection-fighting cells of the body. In adults, leukemia is most common in people older than 55 years, with the average age of diagnosis being 66 years. It is also one of the most common cancers in children and adults younger than 20 years. The survival rate is higher for younger people.
Cancer Risk Factors and Causes
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
How Does Leukemia Kill?
Leukemia is a cancer of the white blood cells of the bone marrow. Patients with leukemia have an over-production of a particular blood cell type in the body, the white blood cells (cells that fight infection, and provide immunity).

What Type of Cancer Makes You Very Tired?
Extreme and recurrent tiredness is one of the common symptoms of most types of cancers. Tiredness is usually considered a warning sign of cancer progressing. Tiredness related to cancers usually does not get better with adequate rest or sleep.
Survival Rate for Acute Lymphoblastic Leukemia
The prognosis depends on the type of leukemia, the extent of the disease, age of the patient, and the general condition of the patient. Some patients can go into complete remission. The average five-year survival rate of leukemia is 60-65%.
Which Cancer Is the Most Painful?
Cancer spreading to the bone is the most painful type of cancer. Pain can be caused by a tumor pressing on the nerves around the bone. As the tumor size increases, it can release chemicals that irritate the area around the tumor.
Is Cancer Contagious?
Cancer is an abnormal growth of cells. A variety of parasites and viruses have been linked to various cancers. Cancer may metastasize, spreading from its original location to other organs. If you have cancer, you should seek medical care immediately if you experience high fever, shortness of breath, intense headaches, vomiting blood or passing blood rectally, chest pain or moderate to severe weakness, passing out (fainting), mental status changes, or seizures.
Cancer fatigue is a lack of energy that is caused by cancer or cancer treatment, including chemotherapy, radiation, biological therapy, or bone marrow transplantation. Strategies to combat cancer fatigue include scheduling rest, pacing oneself, planning ahead and prioritizing work and activities, eating the right foods, exercising, and practicing proper body mechanics.
What Is the BRCA Gene?
BRCA genes (BRCA 1 and 2, when normal, repair damaged DNA) are among the genetic mutations linked to breast cancer, ovarian cancer, and other cancers when mutated. Every woman with a BRCA mutation is at high risk for breast cancer, irrespective of whether she has a family history of breast cancer or not. By age 80, a woman with a BRCA mutation has about an 80% chance of developing breast cancer. BRCA1 and BRCA2 gene mutations also increase the risk of ovarian cancer, by 54% and 23%, respectively.
Certain behavioral, lifestyle, and environmental factors contribute to cancer. Cancer prevention involves modifying these factors to decrease cancer risk. Tobacco use, alcohol consumption, physical inactivity, inadequate fruit and vegetable intake, and obesity increase the risk of certain cancers. Vaccines, genetic testing, and cancer screening also play a role in cancer prevention.
What Are the Stages of Chronic Lymphocytic Leukemia?
Chronic lymphocytic leukemia is a cancer of the blood and bone marrow. With this type of cancer, the marrow creates too many abnormal lymphocytes. There are five stages of chronic lymphocytic leukemia.
Childhood Acute Lymphoblastic Leukemia (ALL)
Childhood acute lymphoblastic leukemia is the most common type of cancer in children. Symptoms and signs include fever, easy bruising, bone or joint pain, weakness, loss of appetite, and painless lumps in the neck, underarm, stomach, or groin. Treatment depends upon staging and may include chemotherapy, radiation, or stem cell transplant.
Cancer pain results from the tumor pressing on nerves or invading bones or organs. Cancer treatments like chemotherapy, radiation, or surgery can also cause pain. Over-the-counter pain relievers, prescription medications, radiation, biofeedback, and relaxation techniques are just some treatments for cancer pain.
Leukemia: Signs, Symptoms, And Complications
Leukemia results when the genetic material (DNA) of a single cell in the bone marrow transforms, this is called a mutation. A mutated cell does not perform body function, but it eats away the nutrition meant for the normal cells.
What Are the 15 Common Signs of Cancer?
The term cancer is given to a group of diseases characterized by the uncontrolled growth of abnormal cells in the body. Some of the common signs of cancer include unintended weight loss, fatigue, bleeding, presence of a mass, persistent cough, abdominal pain and other signs.
