Description

What is Lynparza (olaparib) for?

Lynparza (olaparib) is indicated a poly (ADP-ribose) polymerase (PARP) inhibitor for the treatment of people with:

  • ovarian, fallopian tube or primary peritoneal cancer

    • for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer, who are in a complete or partial response to platinum-based chemotherapy[1,2,3]

  • ovarian cancer

    • for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy[1]

  • breast cancer

    • in patients with deleterious or suspected deleterious gBRCAm, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who have previously been treated with chemotherapy[1].

How does Lynparza (olaparib) work?

PARP enzymes take part in normal cellular functions, including the transcription and repair of DNA.

In healthy cells, the reparation of DNA can happen via alternative mechanisms which do not involve the PAPR enzymes. These mechanisms require BRCA1 and BRCA2 proteins. Cancer cells with a mutation in BRCA1 or BRCA2 genes are not able to use these alternative mechanisms to repair their DNA, thus, when the remaining mechanism available (PARP enzymes mediated repair) is blocked by a PARP inhibitor such as olaparib, the damaged DNA in cancer cells cannot be repaired, and as a result, the cancer cells die[6,1]. In this way, Lynparza (olaparib) helps in the elimination of cancer cells.

BRCA gene mutations occur in approximately 15 to 20% of patients with ovarian cancer[4], approximately 20 to 25% of patients with hereditary breast cancers and 5 to 10% of patients with any type of breast cancer[8]. Although normally BRCA genes are involved in the reparation of damaged DNA and thus work to prevent tumour development when mutations in these genes can lead to the formation of tumours.

Where has Lynparza (olaparib) been approved?

Lynparza (olaparib) was approved by:

  • Food and Drug Administration (FDA), USA:

    • December 19, 2014[4], with an accelerated approval for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy

    • August 17, 2017, for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer, who are in a complete or partial response to platinum-based chemotherapy[9]

    • in patients with deleterious or suspected deleterious gBRCAm, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who have previously been treated with chemotherapy in the neoadjuvant, adjuvant or metastatic setting[8].

  • European Medical Agency (EMA), European Union (January 9, 2015[6]) and Therapeutic Goods Administration (TGA), Australia (January 7, 2016[7]):

    • monotherapy for the maintenance treatment of adult patients with platinum-sensitive relapsed BRCA-mutated high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete response or partial response) to platinum-based chemotherapy[2,3].

  • Health Canada (May 3, 2019[11])
    • Maintenance treatment of adult patients with advanced BRCA-mutated high-grade epithelial ovarian, fallopian tube or primary peritoneal cancer who are in response (complete response or partial response) to first-line platinum-based chemotherapy. Patients must have confirmation of BRCA mutation (identified by either germline or tumour testing) before LYNPARZA treatment is initiated

    • Maintenance treatment of adult patients with platinum-sensitive relapsed (PSR) BRCAmutated high-grade epithelial ovarian, fallopian tube or primary peritoneal cancer who are in response (complete response or partial response) to platinum-based chemotherapy

    • Treatment of adult patients with deleterious or suspected deleterious germline BRCAmutated (gBRCAm), human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer who have previously been treated with chemotherapy in the neoadjuvant, adjuvant or metastatic setting. Patients with hormone receptor (HR)- positive breast cancer should have progressed on or be considered inappropriate for endocrine therapy. Germline BRCA mutation must be confirmed before LYNPARZA treatment is initiated[11].

This medicine has also been approved in Japan for certain indications. Please note that this medicine may have also been approved in other regions than the ones we’ve listed. If you have a question about its approval in a specific country feel free to contact our support team.

Maintenance therapy is the treatment of cancer typically following an initial round of treatment. It is usually given to patients whose cancer is undetectable after previous treatment, and it thus aims at either slowing the cancer’s return or lengthening the life of patients with advanced cancer[10].

How is Lynparza (olaparib) taken?

The standard dosage of Lynparza (olaparib) capsules is:

  • 400 mg (8 capsules of 50 mg) taken twice daily[2,3]

  • Continue treatment until disease progression.

The standard dosage of Lynparza (olaparib) tablets is:

  • 300 mg taken twice daily[1]

  • Continue treatment until disease progression or unacceptable toxicity.

Please note that we’re unable to source Lynparza (olaparib) tablets due to import regulation restrictions.

Complete information about Lynparza (olaparib) dosage and administration can be found in the official prescribing information listed in our resources section[1,2,3].

Lynparza (olaparib) is available as capsules (USA, European Union, Australia) and tablets (USA only). There are differences in the dosing and absorption in the body of each formulation. Tablets and capsules are thus not interchangeable.

Note: Please consult with your treating doctor for personalised dosing.

Are there any known adverse reactions or side effects of Lynparza (olaparib)?

Common adverse reactions

The most common adverse reactions listed in the prescribing information include[1,2,3]:

  • nausea

  • vomiting

  • diarrhoea

  • fatigue

  • headache

  • dysgeusia (distortion of the sense of taste)

  • abnormalities in blood counts.

Serious adverse reactions

The serious adverse reactions listed in the prescribing information include[1,2,3]:

  • Myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) occurred in less than 1.5% of patients and the majority of events had a fatal outcome. All patients had potential contributing factors (previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy)

  • Pneumonitis occurred in less than 1% of patients exposed to Lynparza, and were in some cases fatal.

Use in specific populations

Lynparza (olaparib) could cause fetal harm when administered to a pregnant woman. Lynparza should not be used during pregnancy and reliable contraception should be used during therapy and for 1 month after receiving the last dose of Lynparza. Breastfeeding whilst taking Lynparza is not advised[1,2,3].
