Classification: PARP inhibitor

About Rucaparib (Rubraca™)

Rucaparib is a PARP (poly ADP ribose polymerase) inhibitor. Cancers related to BRCA 1 or 2 mutations seem to rely on PARP to repair damaged DNA in cancer cells, allowing them to continue to divide. By inhibiting PARP, tumor growth may be slowed or stopped. A blood test is required prior to starting treatment with rucaparib to determine if you have a BRCA mutation.

How to take Rucaparib

Rucaparib comes in a tablet form and it should be taken twice daily, about 12 hours apart, with or without food. The tablets come in several dosage sizes. Be sure to double check your prescribed dose and the dose of the tablets you are given before taking each dose.

If you miss a dose, do not take two doses to make up for a missed dose. If you vomit after taking your dose, do not take another dose. Take the next dose at its normally scheduled time. Consult with your pharmacist or provider if you are having trouble swallowing the medication.

Storage and Handling of Rucaparib

Store your medication in the original, labeled container, at room temperature, and in a dry location (unless otherwise directed by your healthcare provider or pharmacist). This medication should not be stored in a pillbox. Keep containers out of reach of children and pets.

If a caregiver prepares your dose for you, they should wear gloves or pour the pills directly from their container into the cap, a small cup, or directly into your hand. They should not touch the pills. They should always wash their hands before and after giving you the medication. Pregnant or nursing women should not prepare the dose for you. Ask your oncology team where to return any unused medication for disposal. Do not flush down the toilet or throw in the trash.

Where do I get this medication?

Rucaparib is available through select specialty pharmacies. Your oncology team will work with your prescription drug plan to identify an in-network specialty pharmacy for distribution of this medication and shipment directly to your home.

Insurance Information for Rucaparib

This medication may be covered under your prescription drug plan. Patient assistance may be available to qualifying individuals without prescription drug coverage. Co-pay cards, which reduce the patient co-pay responsibility for eligible commercially (non-government sponsored) insured patients, may also be available. Your care team can help you find these resources, if they are available.

Possible Side Effects

There are a number of things you can do to manage the side effects of rucaparib. Talk to your doctor or nurse about these recommendations. They can help you decide what will work best for you. These are some of the most common side effects:

Nausea and/or Vomiting 

Talk to your doctor or nurse so they can prescribe medications to help you manage nausea and vomiting. In addition, dietary changes may help. Avoid things that may worsen the symptoms, such as heavy or greasy/fatty, spicy or acidic foods (lemons, tomatoes, oranges). Try antacids, (e.g. milk of magnesia, calcium tablets such as Tums), saltines, or ginger ale to lessen symptoms.

Call your doctor or nurse if you are unable to keep fluids down for more than 12 hours or if you feel lightheaded or dizzy at any time.

Diarrhea 

Your oncology team can recommend medications to relieve diarrhea. Also, try eating low-fiber, bland foods, such as white rice and boiled or baked chicken. Avoid raw fruits, vegetables, whole grain breads, cereals and seeds. Soluble fiber is found in some foods and absorbs fluid, which can help relieve diarrhea. Foods high in soluble fiber include: applesauce, bananas (ripe), canned fruit, orange sections, boiled potatoes, white rice, products made with white flour, oatmeal, cream of rice, cream of wheat, and farina. Drink 8-10 glasses on non-alcoholic, un-caffeinated fluid a day to prevent dehydration. 

Constipation 

There are several things you can do to prevent or relieve constipation. Include fiber in your diet (fruits and vegetables), drink 8-10 glasses of non-alcoholic fluids a day, and keep active. A stool softener once or twice a day may prevent constipation. If you do not have a bowel movement for 2-3 days, you should contact your healthcare team for suggestions to relieve the constipation 

Low White Blood Cell Count (Leukopenia or Neutropenia) 

White blood cells (WBC) are important for fighting infection. While receiving treatment, your WBC count can drop, putting you at a higher risk of getting an infection. You should let your doctor or nurse know right away if you have a fever (temperature greater than 100.4), sore throat or cold, shortness of breath, cough, burning with urination, or a sore that doesn't heal.

Tips to preventing infection: 

  • Washing hands, both yours and your visitors, is the best way to prevent the spread of infection. 
  • Avoid large crowds and people who are sick (i.e.: those who have a cold, fever or cough or live with someone with these symptoms). 
  • When working in your yard, wear protective clothing including long pants and gloves. 
  • Do not handle pet waste. 
  • Keep all cuts or scratches clean. 
  • Shower or bath daily and perform frequent mouth care
  • Do not cut cuticles or ingrown nails. You may wear nail polish, but not fake nails. 
  • Ask your doctor or nurse before scheduling dental appointments or procedures. 
  • Ask your doctor or nurse before you, or someone you live with, has any vaccinations. 

Low Red Blood Cell Count (Anemia) 

Your red blood cells are responsible for carrying oxygen to the tissues in your body. When the red cell count is low, you may feel tired or weak. You should let your doctor or nurse know if you experience any shortness of breath, difficulty breathing or pain in your chest. If the count gets too low, you may receive a blood transfusion.  

Low Platelet Count (Thrombocytopenia) 

Platelets help your blood clot, so when the count is low you are at a higher risk of bleeding. Let your doctor or nurse know if you have any excess bruising or bleeding, including nose bleeds, bleeding gums or blood in your urine or stool. If the platelet count becomes too low, you may receive a transfusion of platelets. 

  • Do not use a razor (an electric razor is fine). 
  • Avoid contact sports and activities that can result in injury or bleeding. 
  • Do not take aspirin (salicylic acid), non-steroidal, anti-inflammatory medications (NSAIDs) such as Motrin®, Aleve®, Advil®, etc. as these can all increase the risk of bleeding. Unless your healthcare team tells you otherwise, you may take acetaminophen (Tylenol). 
  • Do not floss or use toothpicks and use a soft-bristle toothbrush to brush your teeth. 

Fatigue 

Fatigue is very common during cancer treatment and is an overwhelming feeling of exhaustion that is not usually relieved by rest. While on cancer treatment, and for a period after, you may need to adjust your schedule to manage fatigue. Plan times to rest during the day and conserve energy for more important activities. Exercise can help combat fatigue; a simple daily walk with a friend can help.  Talk to your healthcare team for helpful tips on dealing with this side effect. 

Decrease in Appetite & Changes in Taste

Nutrition is an important part of your care. Cancer treatment can affect your appetite and, in some cases, the side effects of treatment can make eating difficult. Ask your nurse about nutritional counseling services at your treatment center to help with food choices. 

  • Try to eat five or six small meals or snacks throughout the day, instead of 3 larger meals. 
  • If you are not eating enough, nutritional supplements may help. 
  • You may experience a metallic taste or find that food has no taste at all. You may dislike foods or beverages that you liked before receiving cancer treatment. These symptoms can last for several months or longer after treatment ends.  
  • Avoid any food that you think smells or tastes bad. If red meat is a problem, eat chicken, turkey, eggs, dairy products and fish without a strong smell. Sometimes cold food has less of an odor.  
  • Add extra flavor to meat or fish by marinating it in sweet juices, sweet and sour sauce or dressings. Use seasonings like basil, oregano or rosemary to add flavor. Bacon, ham and onion can add flavor to vegetables.  

Abdominal Pain

Patients taking this medication may experience pain in their abdomen or stomach. Let your provider know if this occurs, as it can also be a sign of other issues, including severe constipation, bowel obstruction or tumor progression.

Sun Sensitivity 

This medication can make your skin more sensitive to the sun, which can result in severe sunburn or rash. Sun sensitivity can last even after chemotherapy is completed. Avoid the sun between 10-2pm, when it is strongest. Wear sunscreen (at least SPF 15) everyday; wear sunglasses, a hat and long sleeves/pants to protect your skin and seek out shade whenever possible.  

Changes in Laboratory Blood Tests

This medication can cause a number of changes in your blood work, including an increase in creatinine (kidney function), ALT and AST (liver function), and cholesterol. These changes can be a sign of liver and/or kidney damage. Your lab work will be checked frequently while taking this medication. There may be a decrease in blood counts, including a decrease in hemoglobin, white blood cells, and platelets.

Secondary Malignancies  

There is a low risk of developing Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML) when taking this medication. You will have blood tests done frequently to monitor your blood cell counts. Tell your healthcare provider if you are having any of the following side effects: weakness, weight loss, fever, frequent infections, blood in urine or stool, shortness of breath, feeling very tired, bruising or bleeding easily.

Reproductive Concerns

Exposure of an unborn child to this medication could cause birth defects, so you should not become pregnant or father a child while on this medication. Effective birth control is necessary during treatment and for at least 6 months after treatment. Even if your menstrual cycle stops or you believe you are not producing sperm, you could still be fertile and conceive. You should not breastfeed while receiving this medication and for two weeks after your last dose.
