* Description
=====Myelodysplastic syndrome/Acute Myeloid Leukemia=====


====Precautions====
*Myelodysplastic syndrome/Acute Myeloid Leukemia (MDS/AML) have been confirmed in 6 out of 298 (2%) patients enrolled in a single arm trial of Lynparza monotherapy, in patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) advanced cancers. In a randomized placebo controlled trial, MDS/AML occurred in 3 out of 136 (2%) patients with advanced ovarian cancer treated with Lynparza. Overall, MDS/AML were reported in 22 of 2,618 (<1%) patients treated with Lynparza. The majority of MDS/AML cases (17 of 22 cases) were fatal, and the duration of therapy with Lynparza in patients who developed secondary MDS/cancer-therapy related AML varied from <6 months to >2 years. All patients had previous chemotherapy with platinum agents and/or other DNA damaging agents.


* Description
*Monitor complete blood count testing at baseline and monthly thereafter. Do not start Lynparza until patients have recovered from hematological toxicity caused by previous chemotherapy (≤CTCAE Grade 1). For prolonged hematological toxicities, interrupt Lynparza and monitor blood counts weekly until recovery. If the levels have not recovered to CTCAE Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Lynparza.


<!--Adverse Reactions-->
=====Pneumonitis=====


<!--Clinical Trials Experience-->
*Pneumonitis, including fatal cases, occurred in <1% of patients treated with Lynparza. If patients present with new or worsening respiratory symptoms such as dyspnea, fever, cough, wheezing, or a radiological abnormality occurs, interrupt treatment with Lynparza and initiate prompt investigation. If pneumonitis is confirmed, discontinue Lynparza.


|clinicalTrials=
=====Embryo-Fetal Toxicity=====


There is limited information regarding <i>Clinical Trial Experience</i> of {{PAGENAME}} in the drug label.
*Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. Olaparib was teratogenic and caused embryo-fetal toxicity in rats at exposures below those in patients receiving the recommended human dose of 400 mg twice daily. If the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus [seeUSE IN SPECIFIC POPULATIONS (8.1)].


=====Body as a Whole=====
*Advise females of reproductive potential to avoid becoming pregnant while taking Lynparza. If contraceptive methods are being considered, use effective contraception during treatment and for at least one month after receiving the last dose of Lynparza

*The following adverse reactions are discussed elsewhere in the labeling:


:*Myelodysplastic syndrome/Acute Myeloid Leukemia
:*Pneumonitis
=====Clinical Trial Experience=====


=====Neurologic=====
*Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


*Lynparza 400 mg twice daily as monotherapy, has been studied in 300 patients with gBRCA-mutated advanced ovarian cancer, and 223 of these patients had received 3 or more prior lines of chemotherapy.


*In the 223 patients with gBRCA-mutated ovarian cancer who received 3 or more prior lines of chemotherapy (including 137 patients in Study 1 with measureable disease) , adverse reactions led to dose interruption in 40% of patients, dose reduction in 4%, and discontinuation in 7%. There were 8 (4%) patients with adverse reactions leading to death, two were attributed to acute leukemia, and one each was attributed to COPD, cerebrovascular accident, intestinal perforation, pulmonary embolism, sepsis, and suture rupture. Table 1 presents the frequency of adverse reactions reported in ≥20% of 223 patients (in 6 studies) with gBRCA-mutated advanced ovarian cancer who had received 3 or more prior lines of chemotherapy who were treated with Lynparza 400 mg twice daily. The median exposure to Lynparza in these patients was 158 days.=====Hematologic and Lymphatic=====

=====Respiratory=====
*The following adverse reactions and laboratory abnormalities have been identified in ≥10 to <20% of the 223 patients receiving Lynparza and not included in the table: cough, constipation, dysgeusia, peripheral edema, back pain, dizziness, headache, urinary tract infection, dyspnea, and rash. The following adverse reactions and laboratory abnormalities have been identified in ≥1 to <10% of the 223 patients receiving Lynparza and not included in the table: leukopenia, stomatitis, peripheral neuropathy, pyrexia, hypomagnesemia, hyperglycemia, anxiety, depression, insomnia, dysuria, urinary incontinence, vulvovaginal disorder, dry skin/ eczema, pruritis, hypertension, venous thrombosis (including pulmonary embolism), and hot flush.


*Table 3 presents adverse reactions reported in ≥20% of patients from a randomized trial of Lynparza 400 mg twice daily as maintenance monotherapy compared to placebo in patients with platinum sensitive, relapsed, high-grade serous ovarian cancer following treatment with 2 or more platinum-containing regimens. Table 4 presents the laboratory abnormalities in patients from this randomized trial. Of the 96 patients with gBRCA-mutation, 53 received Lynparza, and 43 received placebo. The median duration on treatment with Lynparza was 11.1 months for patients with a gBRCA mutation compared to 4.4 months for patients with gBRCA mutation on placebo.


*Adverse reactions led to dose interruptions in 26% of those receiving Lynparza and 7% of those receiving placebo; dose reductions in 15% of Lynparza and 5% of placebo patients; and discontinuation in 9% of Lynparza and 0% in placebo patients. One (2%) patient on Lynparza died as a result of an adverse reaction.

<!--Drug Interactions-->


|drugInteractions=


=====Cardiovascular=====
* Olaparib is primarily metabolized by CYP3A.


=====Anticancer Agents=====


*Clinical studies of Lynparza in combination with other myelosuppressive anticancer agents, including DNA damaging agents, indicate a potentiation and prolongation of myelosuppressive toxicity.


=====Digestive=====
=====Drugs that may Increase Olaparib Plasma Concentrations=====


*In patients (N=57), co-administration of itraconazole, a strong CYP3A inhibitor, increased AUC of olaparib by 2.7-fold. A moderate CYP3A inhibitor, fluconazole, is predicted to increase the AUC of olaparib by 2-fold.


*Avoid concomitant use of strong CYP3A inhibitors (e.g., itraconazole, telithromycin, clarithromycin, ketoconazole, voriconazole, nefazodone, posaconazole, ritinovir, lopinavir/ritinovir, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) and moderate CYP3A inhibitors (e.g., amprenavir, aprepitant, atazanavir, ciprofloxacin, crizotinib, darunavir/ritonavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib, verapamil). If the strong or moderate CYP3A inhibitors must be co-administered, reduce the dose of Lynparza .


=====Endocrine=====
*Avoid grapefruit and Seville oranges during Lynparza treatment .


=====Drugs that may Decrease Olaparib Plasma Concentrations=====


*In patients (N=22), co-administration of rifampicin, a strong CYP3A inducer, decreased AUC of olaparib by 87%. A moderate CYP3A inducer, efavirenz, is predicted to decrease the AUC of olaparib by 50-60%.


=====Hematologic and Lymphatic=====
*Avoid concomitant use of strong CYP3A inducers (e.g., phenytoin, rifampicin, carbamazepine, St. John’s Wort) and moderate CYP3A4 inducers (e.g., bosentan, efavirenz, etravirine, modafinil, nafcillin). If a moderate CYP3A inducer cannot be avoided, be aware of a potential for decreased efficacy of Lynparza
<!--Use in Specific Populations-->


|useInPregnancyFDA=
Pregnancy Category D
=====Risk summary=====


*Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. Olaparib was teratogenic and caused embryo-fetal toxicity in rats at exposures below those in patients receiving the recommended human dose of 400 mg twice daily. If this drug is used during pregnancy, or if a patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to the fetus and the potential risk for loss of the pregnancy.


=====Metabolic and Nutritional=====
=====Animal Data=====


*In a fertility and early embryonic development study in female rats, olaparib was administered orally for 14 days before mating through to day 6 of pregnancy, which resulted in increased post-implantation loss at a dose level of 15 mg/kg/day (with maternal systemic exposures approximately 11% of the human exposure (AUC0-24h) at the recommended dose).


*In an embryo-fetal development study, pregnant rats received oral doses of 0.05 and 0.5 mg/kg/day olaparib during the period of organogenesis. A dose of 0.5 mg/kg/day (with maternal systemic exposures approximately 0.3% of human exposure (AUC0-24h) at the recommended dose) caused embryo-fetal toxicities including increased post-implantation loss and major malformations of the eyes (anophthalmia, microphthalmia), vertebrae/ribs (extra rib or ossification center; fused or absent neural arches, ribs, and sternebrae), skull (fused exoccipital) and diaphragm (hernia). Additional abnormalities or variants included incomplete or absent ossification (vertebrae/sternebrae, ribs, limbs) and other findings in the vertebrae/sternebrae, pelvic girdle, lung, thymus, liver, ureter and umbilical artery. Some findings noted above in the eyes, ribs and ureter were observed at a dose of 0.05 mg/kg/day olaparib at lower incidence.

  • Content
Myelodysplastic syndrome/Acute Myeloid Leukemia
  • Myelodysplastic syndrome/Acute Myeloid Leukemia (MDS/AML) have been confirmed in 6 out of 298 (2%) patients enrolled in a single arm trial of Lynparza monotherapy, in patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) advanced cancers. In a randomized placebo controlled trial, MDS/AML occurred in 3 out of 136 (2%) patients with advanced ovarian cancer treated with Lynparza. Overall, MDS/AML were reported in 22 of 2,618 (<1%) patients treated with Lynparza. The majority of MDS/AML cases (17 of 22 cases) were fatal, and the duration of therapy with Lynparza in patients who developed secondary MDS/cancer-therapy related AML varied from <6 months to >2 years. All patients had previous chemotherapy with platinum agents and/or other DNA damaging agents.
  • Monitor complete blood count testing at baseline and monthly thereafter. Do not start Lynparza until patients have recovered from hematological toxicity caused by previous chemotherapy (≤CTCAE Grade 1). For prolonged hematological toxicities, interrupt Lynparza and monitor blood counts weekly until recovery. If the levels have not recovered to CTCAE Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Lynparza.
Pneumonitis
  • Pneumonitis, including fatal cases, occurred in <1% of patients treated with Lynparza. If patients present with new or worsening respiratory symptoms such as dyspnea, fever, cough, wheezing, or a radiological abnormality occurs, interrupt treatment with Lynparza and initiate prompt investigation. If pneumonitis is confirmed, discontinue Lynparza.
Embryo-Fetal Toxicity
  • Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. Olaparib was teratogenic and caused embryo-fetal toxicity in rats at exposures below those in patients receiving the recommended human dose of 400 mg twice daily. If the patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to a fetus [seeUSE IN SPECIFIC POPULATIONS (8.1)].
  • Advise females of reproductive potential to avoid becoming pregnant while taking Lynparza. If contraceptive methods are being considered, use effective contraception during treatment and for at least one month after receiving the last dose of Lynparza

Adverse Reactions

Clinical Trials Experience

  • The following adverse reactions are discussed elsewhere in the labeling:
  • Myelodysplastic syndrome/Acute Myeloid Leukemia
  • Pneumonitis
Clinical Trial Experience
  • Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
  • Lynparza 400 mg twice daily as monotherapy, has been studied in 300 patients with gBRCA-mutated advanced ovarian cancer, and 223 of these patients had received 3 or more prior lines of chemotherapy.
  • In the 223 patients with gBRCA-mutated ovarian cancer who received 3 or more prior lines of chemotherapy (including 137 patients in Study 1 with measureable disease) , adverse reactions led to dose interruption in 40% of patients, dose reduction in 4%, and discontinuation in 7%. There were 8 (4%) patients with adverse reactions leading to death, two were attributed to acute leukemia, and one each was attributed to COPD, cerebrovascular accident, intestinal perforation, pulmonary embolism, sepsis, and suture rupture. Table 1 presents the frequency of adverse reactions reported in ≥20% of 223 patients (in 6 studies) with gBRCA-mutated advanced ovarian cancer who had received 3 or more prior lines of chemotherapy who were treated with Lynparza 400 mg twice daily. The median exposure to Lynparza in these patients was 158 days.=====Hematologic and Lymphatic=====

TABLE02

  • The following adverse reactions and laboratory abnormalities have been identified in ≥10 to <20% of the 223 patients receiving Lynparza and not included in the table: cough, constipation, dysgeusia, peripheral edema, back pain, dizziness, headache, urinary tract infection, dyspnea, and rash. The following adverse reactions and laboratory abnormalities have been identified in ≥1 to <10% of the 223 patients receiving Lynparza and not included in the table: leukopenia, stomatitis, peripheral neuropathy, pyrexia, hypomagnesemia, hyperglycemia, anxiety, depression, insomnia, dysuria, urinary incontinence, vulvovaginal disorder, dry skin/ eczema, pruritis, hypertension, venous thrombosis (including pulmonary embolism), and hot flush.
  • Table 3 presents adverse reactions reported in ≥20% of patients from a randomized trial of Lynparza 400 mg twice daily as maintenance monotherapy compared to placebo in patients with platinum sensitive, relapsed, high-grade serous ovarian cancer following treatment with 2 or more platinum-containing regimens. Table 4 presents the laboratory abnormalities in patients from this randomized trial. Of the 96 patients with gBRCA-mutation, 53 received Lynparza, and 43 received placebo. The median duration on treatment with Lynparza was 11.1 months for patients with a gBRCA mutation compared to 4.4 months for patients with gBRCA mutation on placebo.
  • Adverse reactions led to dose interruptions in 26% of those receiving Lynparza and 7% of those receiving placebo; dose reductions in 15% of Lynparza and 5% of placebo patients; and discontinuation in 9% of Lynparza and 0% in placebo patients. One (2%) patient on Lynparza died as a result of an adverse reaction.

TABLE03

Postmarketing Experience

There is limited information regarding Postmarketing Experience of Olaparib in the drug label.

Drug Interactions

  • Olaparib is primarily metabolized by CYP3A.
Anticancer Agents
  • Clinical studies of Lynparza in combination with other myelosuppressive anticancer agents, including DNA damaging agents, indicate a potentiation and prolongation of myelosuppressive toxicity.
Drugs that may Increase Olaparib Plasma Concentrations
  • In patients (N=57), co-administration of itraconazole, a strong CYP3A inhibitor, increased AUC of olaparib by 2.7-fold. A moderate CYP3A inhibitor, fluconazole, is predicted to increase the AUC of olaparib by 2-fold.
  • Avoid concomitant use of strong CYP3A inhibitors (e.g., itraconazole, telithromycin, clarithromycin, ketoconazole, voriconazole, nefazodone, posaconazole, ritinovir, lopinavir/ritinovir, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) and moderate CYP3A inhibitors (e.g., amprenavir, aprepitant, atazanavir, ciprofloxacin, crizotinib, darunavir/ritonavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib, verapamil). If the strong or moderate CYP3A inhibitors must be co-administered, reduce the dose of Lynparza .
  • Avoid grapefruit and Seville oranges during Lynparza treatment .
Drugs that may Decrease Olaparib Plasma Concentrations
  • In patients (N=22), co-administration of rifampicin, a strong CYP3A inducer, decreased AUC of olaparib by 87%. A moderate CYP3A inducer, efavirenz, is predicted to decrease the AUC of olaparib by 50-60%.
  • Avoid concomitant use of strong CYP3A inducers (e.g., phenytoin, rifampicin, carbamazepine, St. John’s Wort) and moderate CYP3A4 inducers (e.g., bosentan, efavirenz, etravirine, modafinil, nafcillin). If a moderate CYP3A inducer cannot be avoided, be aware of a potential for decreased efficacy of Lynparza

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): Pregnancy Category D

Risk summary
  • Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. Olaparib was teratogenic and caused embryo-fetal toxicity in rats at exposures below those in patients receiving the recommended human dose of 400 mg twice daily. If this drug is used during pregnancy, or if a patient becomes pregnant while taking this drug, apprise the patient of the potential hazard to the fetus and the potential risk for loss of the pregnancy.
Animal Data
  • In a fertility and early embryonic development study in female rats, olaparib was administered orally for 14 days before mating through to day 6 of pregnancy, which resulted in increased post-implantation loss at a dose level of 15 mg/kg/day (with maternal systemic exposures approximately 11% of the human exposure (AUC0-24h) at the recommended dose).
  • In an embryo-fetal development study, pregnant rats received oral doses of 0.05 and 0.5 mg/kg/day olaparib during the period of organogenesis. A dose of 0.5 mg/kg/day (with maternal systemic exposures approximately 0.3% of human exposure (AUC0-24h) at the recommended dose) caused embryo-fetal toxicities including increased post-implantation loss and major malformations of the eyes (anophthalmia, microphthalmia), vertebrae/ribs (extra rib or ossification center; fused or absent neural arches, ribs, and sternebrae), skull (fused exoccipital) and diaphragm (hernia). Additional abnormalities or variants included incomplete or absent ossification (vertebrae/sternebrae, ribs, limbs) and other findings in the vertebrae/sternebrae, pelvic girdle, lung, thymus, liver, ureter and umbilical artery. Some findings noted above in the eyes, ribs and ureter were observed at a dose of 0.05 mg/kg/day olaparib at lower incidence.


Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Olaparib in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Olaparib during labor and delivery.

Nursing Mothers

  • It is not known whether olaparib is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from olaparib, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

  • The safety and efficacy of Lynparza has not been established in pediatric patients.

Geriatic Use

  • In clinical studies of Lynparza enrolling 735 patients with advanced solid tumors [the majority (69%) of whom had ovarian cancer] who received Lynparza 400 mg twice daily as monotherapy, 148 (20%) of patients were aged ≥65 years. The safety profile was similar irrespective of age with the exception of AEs of CTCAE ≥3 which were reported more frequently in patients aged ≥65 years (53.4%) than those <65 years (43.4%). No individual adverse event or System Organ Class accounted for this observed difference.

Gender

There is no FDA guidance on the use of Olaparib with respect to specific gender populations.

Race

There is no FDA guidance on the use of Olaparib with respect to specific racial populations.

Renal Impairment

  • Based on preliminary data, a 1.5 fold increase in mean exposure (AUC) was observed in patients with mild renal impairment (CLcr = 50-80 mL/min) compared to patients with normal renal function (CLcr >80 mL/min). No dose adjustment to the starting dose is required in patients with CLcr of 50 to 80 mL/min, but patients should be monitored closely for toxicity. There are no data in patients with moderate or severe renal impairment (CLcr <50 mL/min) or patients on dialysis

Hepatic Impairment

  • The effect of hepatic impairment on exposure to Lynparza has not been studied. Patients with bilirubin >1.5 X ULN and AST/ALT ≥2.5 X ULN (≥5 X ULN in the presence of liver metastases) were excluded from Lynparza clinical trials. There are no data in patients with baseline hepatic impairment (serum bilirubin >1.5 X ULN)

Females of Reproductive Potential and Males

  • Lynparza can cause fetal harm when administered to a pregnant woman . Advise female patients of reproductive potential to avoid pregnancy while taking Lynparza. If contraceptive methods are being considered, use highly effective contraception during treatment with Lynparza and for at least one month following the last dose of Lynparza. Instruct patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking Lynparza.

Immunocompromised Patients

There is no FDA guidance one the use of Olaparib in patients who are immunocompromised.
