Treatment Name: Olaparib (Lynparza®)

Olaparib (Lynparza®) is a Chemotherapy Regimen for Ovarian Cancer

How does olaparib (Lynparza®) work?
Olaparib inhibits a family of enzymes called PARP (poly ADP ribose polymerase). When the PARP enzymes are inhibited, cell DNA is severely damaged. In ovarian cancer cells that have a mutation in BRCA (pronounced "Bracka"), the cell is unable to fix the damage and it dies. However, other healthy cells that have a normally functioning BRCA gene will able to fix the damage to the DNA and they will not be affected by olaparib. Olaparib can only be given to patients who have BRCA mutations.

Goals of olaparib therapy:
Olaparib is taken to shrink tumors and decrease symptoms from ovarian cancer but is not commonly given with the goal of cure.

Schedule

  • Usual olaparib (Lynparza®) starting dose: 300 mg (two 150 mg tablets) by mouth twice daily

Olaparib must be dispensed by a specialty pharmacy and is taken at home.

Treatment is continued until the drug no longer works or unacceptable side effects are experienced.

Note: Individual doses may vary based upon your Doctor's recommendation, or drug availability.

Side Effects

In clinical studies, the most commonly reported olaparib (Lynparza®) side effects are shown here. Side effects sometimes have percentage ranges [example 60 – 62%] because they differed between clinical studies:

Roughly 4% of patients discontinue olaparib treatment due to unacceptable side effects.

Monitoring

How often is monitoring needed?
Labs (blood tests) may be checked before treatment and periodically during treatment. Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), CA-125 (a tumor marker for ovarian cancer), plus any others your doctor may order.

How often is imaging needed?
Imaging may be checked before treatment and during treatment at the discretion of your doctor. Imaging may include: X-rays, magnetic resonance imaging (MRI), computerized tomography (CT) scans, or positron emission tomography (PET) scans.

How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue olaparib as planned, delay treatment with olaparib or switch therapy.

ChemoExperts Tips

  • A large number of patients experience nausea while taking olaparib, although the severity is usually mild. Typically, anti-nausea medications do not need to be taken prior to each olaparib dose but patients should have a prescription for an anti-nausea medication to use if needed
  • Olaparib can commonly cause low red and white blood cells, low platelets, and in very rare cases it can lead to the development of bone marrow disorders such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). If you are experiencing unusual bruising or bleeding, severe fatigue and shortness of breath, or frequent infections and fevers, it may be a sign of low blood counts from olaparib or a more serious bone marrow disorder
  • A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
  • Clinical trials may exist for ovarian cancer. Ask your doctor if any studies are currently enrolling in your area. If not, go to clinicaltrials.gov to search for other centers offering study medications

Emotional Wellness

What is Emotional Wellness?
Emotional wellness is having a positive outlook balanced with a realistic understanding of current life events. This requires both an awareness and acceptance of your emotions. It is with this knowledge that you can develop a plan to take the necessary actions to positively impact your life.

Emotional wellness uses an ongoing process to continually reflect on the stressors of life in a constructive manner to move forward and create happiness.

Because emotional wellness is deeply connected with physical, social, and spiritual wellness, pursuing it often becomes particularly difficult in times of major illness. Despite this difficulty, working toward emotional wellness has been connected to improved treatment outcomes and a higher likelihood of achieving goals of therapy.

What is Ovarian Cancer?

What is Ovarian Cancer?
A disease of the cells found in the ovaries in women. Ovarian cancer is not common, but is the fifth leading cause of cancer related death in women. The exact cause is not known, however risk factors include: older age, obesity, first period at an early age, late menopause, hormone replacement therapy (HRT) after menopause, family history, and genetic causes such as the BRCA (pronounced "bracka") mutation. The use of oral contraceptives or having one or more full-term pregnancies can decrease the risk of ovarian cancer.

The stage of ovarian cancer can vary at diagnosis and throughout treatment. Ovarian cancer is staged using the Tumor, Node, Metastasis (TNM) staging system, as well as Stage Grouping I, II, III, or IV. Staging systems describe the extent of cancer throughout the body and help doctors determine which treatments to offer. The effectiveness of the treatment may depend upon the stage at diagnosis.

NOTE: Treatment Options listed below are not all-inclusive. Other treatments may be available. ChemoExperts provides drug information and does not recommend any one treatment over another. Only your Doctor can choose which therapy is appropriate for you.

What does "Cure" mean?

The word “cure” means there are no cancer cells left in the body and cancer will never come back. Depending on the cancer type and stage, this may be the true goal of therapy. However, it is very difficult to prove all cancer cells are gone. Even though images, like X-rays and MRI’s, and blood tests may not show any signs of cancer, there can be a small amount of cancer cells still left in the body. Because of this, doctors use the word “remission” is used more often. This means there are no signs or symptoms of cancer. Patients in remission are followed closely for any signs of cancer returning. Sometimes, more chemotherapy may be given while in remission to prevent the cancer from coming back.

Doctors usually do not consider a patient “cured” until the chance of cancer returning is extremely low. If cancer does return, it usually happens within 5 years of having a remission. Because of this, doctors do not consider a patient cured unless the cancer has not come back within 5 years of remission. The five-year cutoff does not apply to all cancers.

What is a CBC?

A Complete Blood Count (CBC) is a frequently ordered blood test that tells clinicians the status of your: 1) White blood cell count, 2) Hemoglobin, and 3) Platelet count at the time the test was taken.

Common uses:
1) White blood cell count (WBC): is used to determine infection risk, or response to chemotherapy. Certain chemotherapy agents may harm our good infection-fighting cells. Sometimes chemotherapy may need to be delayed to allow these cells to recover.

2) Hemoglobin: is used to determine if someone is anemic. Anytime the hemoglobin is below 12 g/dL, the person is said to be anemic. Red blood cell transfusions, and sometimes iron can be given to restore the hemoglobin level, but anemia treatment should always aim at treating the underlying cause or condition.

3) Platelet count: is used to determine if the risk of bleeding is increased or if a platelet transfusion is required to prevent bleeding. Certain medications that increase bleeding risk, such as: aspirin, certain chemotherapy agents, and blood thinners, may need to be stopped temporarily until the platelet count is within a safe range.

What is a CMP?

A Comprehensive Metabolic Panel (CMP) is a frequently ordered blood test that tells clinicians the status of your: 1) Electrolytes & Acid/Base status2) Kidney function, 3) Liver function, 4) Blood sugar, and 5) Calcium at the time the test was taken. It is commonly used to monitor liver and kidney function when beginning new medications such as chemotherapy. A total of 14 tests are run simultaneously and are shown below.

Electrolytes & Acid/Base status:
1) Sodium, 2) Potassium, 3) Carbon dioxide, 4) Chloride

Kidney Function:
5) BUN (blood urea nitrogen), 6) Serum creatinine (Scr)

Liver Function:
7) AST, 8) ALT, 9) Total bilirubin, 10) Alk Phos, 11) Albumin, 12) Total protein

Blood sugar:
13) Serum glucose

Calcium:
14) Serum calcium

What is a specialty pharmacy?

A pharmacy that manages the handling and services for drugs used by patients with rare or chronic diseases. This has expanded in the last several years to include very expensive drugs used to treat cancer, mainly oral cancer medications or injections that can be taken at home.
