Clinical Pharmacology

CLINICAL PHARMACOLOGY Mechanism Of Action Lynparza is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP1, PARP2, and PARP3. PARP enzymes are involved in normal cellular functions, such as DNA transcription and DNA repair. Olaparib has been shown to inhibit growth of select tumor cell lines in vitro and decrease tumor growth in mouse xenograft models of human cancer both as monotherapy or following platinum-based chemotherapy. Increased cytotoxicity and anti-tumor activity following treatment with olaparib were noted in cell lines and mouse tumor models with deficiencies in BRCA and non-BRCA proteins involved in the homologous recombination repair (HRR) of DNA damage and correlated with platinum response. In vitro studies have shown that olaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complex, resulting in disruption of cellular homeostasis and cell death. Pharmacodynamics Cardiac Electrophysiology The effect of olaparib on cardiac repolarization was assessed in 119 patients following a single dose of 300 mg tablets and in 109 patients following multiple dosing of 300 mg tablets twice daily. No clinically relevant effect of olaparib on QT interval was observed. Pharmacokinetics Lynparza is available as a tablet and capsule formulation. The oral bioavailability of the tablet formulation is higher than the capsule formulation. Population pharmacokinetic analyses have shown that the steady state exposure (AUC) following 300 mg tablet twice daily was 77% higher compared to that following 400 mg capsule twice daily. The olaparib geometric mean AUC and Cmax following a single 400 mg capsule dose were 37.2 μg*h/mL (N = 48) and 4.02 μg/mL (N = 48), respectively, and the steady state geometric mean AUC and Cmax following 400 mg capsule twice daily were 43.5 μg*h/mL (N = 48) and 6.18 μg/mL (N = 48), respectively. Olaparib showed time-dependent PK that the steady state clearance decreased by 15% after multiple dosing. Absorption Following oral administration of olaparib via the capsule formulation, absorption is rapid with peak plasma concentrations typically achieved between 1 to 3 hours after dosing. On multiple dosing there is no marked accumulation (accumulation ratio of 1.4 – 1.5 for twice daily dosing), with steady state exposures achieved within 3 to 4 days. Limited data suggest that the systemic exposure (AUC) of olaparib increases less than proportionally with dose over the dose range of 100 to 400 mg, but the PK data were variable across trials. Co-administration with a high fat meal slowed the rate (Tmax delayed by 2 hours) of absorption, but did not significantly alter the extent of olaparib absorption (mean AUC increased by approximately 20%). Distribution Olaparib had a mean (± standard deviation) apparent volume of distribution at steady state of 167 ± 196 L after a single 400 mg dose of olaparib. The in vitro protein binding of olaparib is approximately 82%. Metabolism In vitro, CYP3A4/5 were shown to be the enzymes primarily responsible for the metabolism of olaparib. Following oral dosing of 14C-olaparib to female patients, unchanged olaparib accounted for the majority of the circulating radioactivity in plasma (70%). It was extensively metabolized with unchanged drug accounting for 15% and 6% of radioactivity in urine and feces, respectively. The majority of the metabolism is attributable to oxidation reactions with a number of the components produced undergoing subsequent glucuronide or sulfate conjugation. Excretion A mean (± standard deviation) terminal plasma half-life of 11.9 ± 4.8 hours and apparent plasma clearance of 8.6 ± 7.1 L/h were observed after a single 400 mg dose of olaparib. Following a single dose of 14C-olaparib, 86% of the dosed radioactivity was recovered within a 7-day collection period, 44% via the urine and 42% via the feces. The majority of the material was excreted as metabolites. Drug Interactions Based on the data from a drug-interaction trial (N=57), the AUC and Cmax of olaparib increased by 2.7and 1.4-fold, respectively, when olaparib was administered in combination with itraconazole, a strong CYP3A inhibitor. Simulations suggested that a moderate CYP3A inhibitor (fluconazole) may increase the AUC and Cmax of olaparib by 2.2-and 1.2-fold, respectively. Based on the data from a drug-interaction trial (N=22), the AUC and Cmax of olaparib decreased by 87% and 71%, respectively, when olaparib was administered in combination with rifampicin, a strong CYP3A inducer. Simulations suggested that a moderate CYP3A inducer (efavirenz) may decrease the AUC and Cmax of olaparib by approximately 50% and 30%, respectively. In vitro studies have shown that olaparib is both an inhibitor and inducer of CYP3A and an inducer of CYP2B6. Olaparib is predicted to be a weak CYP3A substrate in humans. In vitro studies also indicated that olaparib is an inhibitor of UGT1A1, BCRP, OATP1B1, OCT1, OCT2, OAT3, MATE1 and MATE2K. The clinical relevance of these findings is unknown. In vitro, olaparib is a substrate of, and inhibits, the efflux transporter P-gp. The potential for olaparib to induce P-gp has not been evaluated. Pharmacokinetics In Specific Populations Hepatic Impairment In a hepatic impairment trial, the mean AUC increased by 15% and the mean Cmax by 13% when olaparib was dosed in patients with mild hepatic impairment (Child-Pugh classification A; N=9) compared with patients with normal hepatic function (N=13). Mild hepatic impairment had no effect on the protein binding of olaparib and therefore total plasma exposure was representative of free drug. There are no data in patients with moderate or severe hepatic impairment. Renal Impairment In a renal impairment trial, the mean AUC increased by 24% and the Cmax increased by 15%, when olaparib was dosed in patients with mild renal impairment (CLcr = 51-80 mL/min defined by the Cockcroft-Gault equation; N=13) and by 44% and 26%, respectively, when olaparib was dosed in patients with moderate renal impairment (CLcr = 31-50 mL/min; N=13), compared to those with normal renal function (CLcr ≥81 mL/min; N=12). There was no evidence of a relationship between the extent of plasma protein binding of olaparib and creatinine clearance. There are no data in patients with severe renal impairment or end-stage renal disease (CLcr ≤ 30 mL/min). Clinical Studies Advanced gBRCA-Mutated Ovarian Cancer Treated With 3 Or More Prior Lines Of Chemotherapy The efficacy of Lynparza was investigated in a single-arm study in patients with deleterious or suspected deleterious gBRCAm advanced cancers. A total of 137 patients with measurable, gBRCAm ovarian cancer treated with three or more prior lines of chemotherapy were enrolled. All patients received Lynparza capsules at a dose of 400 mg twice daily as monotherapy until disease progression or intolerable toxicity. Objective response rate (ORR) and duration of response (DOR) were assessed by the investigator according to RECIST v1.0. The median age of the patients was 58 years, the majority were White (94%) and 93% had an ECOG PS of 0 or 1. Deleterious or suspected deleterious, gBRCAm status was verified retrospectively in 97% (59/61) of the patients for whom blood samples were available by the BRACAnalysis CDx™ . Efficacy results from Study 1 are summarized in Table 5.

Drug Description

Indications & Dosage

INDICATIONS Advanced gBRCA-Mutated Ovarian Cancer After 3 Or More Lines Of Chemotherapy Lynparza is indicated 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. Select patients for therapy based on an FDA-approved companion diagnostic for Lynparza. DOSAGE AND ADMINISTRATION Important Administration Instructions Lynparza is also available as 100 mg and 150 mg tablets. DO NOT substitute Lynparza capsules (50 mg) with Lynparza tablets (100 mg and 150 mg) on a milligram-to-milligram basis due to differences in the dosing and bioavailability of each formulation [see CLINICAL PHARMACOLOGY]. Refer to the full prescribing information for Lynparza tablets for specific tablet dosing. Patient Selection Select patients for the treatment of advanced ovarian cancer with Lynparza based on the presence of deleterious or suspected deleterious germline BRCA-mutations [see INDICATIONS and Clinical Studies]. Information on FDA-approved test for the detection of BRCA-mutations is available at http://www.fda.gov/companiondiagnostics. Recommended Dosing The recommended dose of Lynparza is 400 mg (eight 50 mg capsules) taken orally twice daily with or without food, for a total daily dose of 800 mg. Continue treatment until disease progression or unacceptable toxicity. If a patient misses a dose of Lynparza, instruct patients to take their next dose at its scheduled time. Swallow capsule whole. Do not chew, dissolve, or open capsule. Do not take capsules which appear deformed or show evidence of leakage [see HOW SUPPLIED]. Dose Adjustments For Adverse Reactions To manage adverse reactions, consider interruption of treatment or dose reduction. The recommended dose reduction is 200 mg (four 50 mg capsules) taken twice daily, for a total daily dose of 400 mg. If a further dose reduction is required, then reduce to 100 mg (two 50 mg capsules) taken twice daily, for a total daily dose of 200 mg. Dose Modifications For Use With CYP3A Inhibitors Avoid concomitant use of strong and moderate CYP3A inhibitors and consider alternative agents with less CYP3A inhibition. If the inhibitor cannot be avoided, reduce the Lynparza dose to 150 mg (three 50 mg capsules) taken twice daily for a strong CYP3A inhibitor or 200 mg (four 50 mg capsules) taken twice daily for a moderate CYP3A inhibitor [see DRUG INTERACTIONS]. Dose Modifications For Patients With Renal Impairment Patients with mild renal impairment (CLcr 51-80 mL/min as estimated by Cockcroft-Gault equation) do not require an adjustment in Lynparza dosing. In patients with moderate renal impairment (CLcr 31-50 mL/min) the recommended dose reduction is to 300 mg (six 50 mg capsules) twice daily, for a total daily dose of 600 mg. The pharmacokinetics of olaparib have not been evaluated in patients with severe renal impairment or end-stage renal disease (CLcr ≤30 mL/min) [see Use In Specific Populations and CLINICAL PHARMACOLOGY].

Side Effects & Drug Interactions

SIDE EFFECTS The following adverse reactions are discussed elsewhere in the labeling: Myelodysplastic Syndrome/Acute Myeloid Leukemia [see WARNINGS AND PRECAUTIONS] Pneumonitis [see WARNINGS AND PRECAUTIONS] 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. Treatment Of Advanced gBRCAm Ovarian Cancer After 3 Or More Lines Of Chemotherapy Pooled Data Treatment with Lynparza capsules 400 mg twice daily as monotherapy, was studied in 223 patients (pooled from 6 studies) with gBRCAm advanced ovarian cancer who had received 3 or more prior lines of chemotherapy. Adverse reactions led to dose interruption in 40% of patients, dose reduction in 4% of patients, and discontinuation in 7% of patients. 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. The median exposure to Lynparza in these patients was 5.2 months. Table 1 presents adverse reactions reported in ≥20% of patients and Table 2 presents laboratory abnormalities that occurred in at least 25% of patients from the pooled studies.

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, and venous thrombosis (including pulmonary embolism). Study 19 The safety of Lynparza capsules as maintenance monotherapy was also evaluated in patients with platinum sensitive ovarian cancer who had received 2 or more previous platinum containing regimens in Study 19, a randomized, placebo-controlled, double-blind, multi-center study in which 264 patients received Lynparza 400 mg twice daily (N=136) or placebo (N=128). At the time of final analysis, the median duration of exposure was 8.7 months in patients who received Lynparza and 4.6 months in patients who received placebo. Adverse reactions led to dose interruptions in 35% of those receiving Lynparza and 10% of those receiving placebo; dose reductions in 26% of Lynparza patients and 4% of placebo patients; and discontinuation in 6% of Lynparza patients and 2% in placebo patients. Table 3 summarizes the adverse reactions that occurred in at least 20% of patients who received Lynparza in Study 19. Table 4 presents the laboratory abnormalities that occurred in at least 25% of patients from Study 19.

Postmarketing Experience The following adverse reactions have been identified during post-approval use of Lynparza. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune System Disorders: Hypersensitivity (rash/dermatitis) DRUG INTERACTIONS 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 Olaparib is primarily metabolized by CYP3A. In patients (N=57), co-administration of itraconazole, a strong CYP3A inhibitor, increased AUC of olaparib by 170%. A moderate CYP3A inhibitor, fluconazole, is predicted to increase the AUC of olaparib by 121%. Avoid concomitant use of strong CYP3A inhibitors such as itraconazole, telithromycin, clarithromycin, ketoconazole, voriconazole, nefazodone, posaconazole, ritonavir, lopinavir/ritonavir, indinavir, saquinavir, nelfinavir, boceprevir, and telaprevir. Avoid use of moderate CYP3A inhibitors such as amprenavir, aprepitant, atazanavir, ciprofloxacin, crizotinib, darunavir/ritonavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib, and verapamil. If the strong or moderate CYP3A inhibitors must be co-administered, reduce the dose of Lynparza [see DOSAGE AND ADMINISTRATION]. Avoid grapefruit, grapefruit juice, Seville oranges and Seville orange juice during Lynparza treatment since they are CYP3A inhibitors [see DOSAGE AND ADMINISTRATION and CLINICAL PHARMACOLOGY]. 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 approximately 50%. Avoid concomitant use of strong CYP3A inducers such as phenytoin, rifampicin, carbamazepine, and St. John’s Wort. Avoid concomitant use of moderate CYP3A4 inducers such as bosentan, efavirenz, etravirine, modafinil, and nafcillin. If a moderate CYP3A inducer cannot be avoided, be aware of a potential for decreased efficacy of Lynparza [see CLINICAL PHARMACOLOGY].

Warnings & Precautions

WARNINGS Included as part of the "PRECAUTIONS" Section PRECAUTIONS Myelodysplastic Syndrome/Acute Myeloid Leukemia Overall, the incidence of Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) in patients treated with Lynparza monotherapy in clinical trials, including long-term follow up, was <1.5% (21/1680) and the majority of events had a fatal outcome. Of these, 19/21 patients had a documented BRCA mutation, 1 patient had gBRCA wildtype and in 1 patient the BRCA mutation status was unknown. Additional cases of MDS/AML have been documented in patients treated with Lynparza in combination studies. The duration of therapy with Lynparza in patients who developed secondary MDS/cancer-therapy related AML varied from < 6 months to > 2 years. All of these patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Some of these patients also had a history of previous cancer or bone marrow dysplasia. Do not start Lynparza until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt Lynparza and monitor blood counts weekly until recovery. If the levels have not recovered to 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, cough and fever, or a radiological abnormality occurs, interrupt Lynparza treatment and promptly assess the source of symptoms. If pneumonitis is confirmed, discontinue Lynparza treatment and treat the patient appropriately. Embryo-Fetal Toxicity Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. In an animal reproduction study, administration of olaparib to pregnant rats during the period of organogenesis caused teratogenicity and embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 400 mg twice daily. Apprise pregnant women of the potential hazard to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of Lynparza [see Use In Specific Populations and CLINICAL PHARMACOLOGY]. Patient Counseling Information Advise the patient to read the FDA-approved patient labeling (Medication Guide). Administration Instructions: Inform patients on how to take Lynparza [see DOSAGE AND ADMINISTRATION]. Lynparza should be taken twice daily with or without food. Instruct patients that if they miss a dose of Lynparza, not to take an extra dose to make up for the one that they missed. They should take their next normal dose at the usual time. Each capsule should be swallowed whole. Do not chew, dissolve, or open the capsule. Inform patients to avoid grapefruit, grapefruit juice, Seville oranges, and Seville orange juice while taking Lynparza [see DRUG INTERACTIONS]. Inform patients not to substitute Lynparza capsules (50 mg) with Lynparza tablets (100 mg and 150 mg) on a milligram-to-milligram basis due to differences in the dosing and bioavailability of each formulation [see DOSAGE AND ADMINISTRATION]. MDS/AML: Advise patients to contact their healthcare provider if they experience weakness, feeling tired, fever, weight loss, frequent infections, bruising, bleeding easily, breathlessness, blood in urine or stool, and/or laboratory findings of low blood cell counts, or a need for blood transfusions. This may be a sign of hematological toxicity or a more serious uncommon bone marrow problem called ‘myelodysplastic syndrom e’ (MDS) or ‘acute myeloid leukemia’ (AML) which have been reported in patients treated with Lynparza [see WARNINGS AND PRECAUTIONS]. Pneumonitis: Advise patients to contact their healthcare provider if they experience any new or worsening respiratory symptoms including shortness of breath, fever, cough, or wheezing [see WARNINGS AND PRECAUTIONS]. Embryo-Fetal Toxicity: Advise females to inform their healthcare provider if they are pregnant or become pregnant. Inform female patients of the risk to a fetus and potential loss of the pregnancy [see Use In Specific Populations]. Advise females of reproductive potential to use effective contraception during treatment with Lynparza and for 6 months after receiving the last dose [see WARNINGS AND PRECAUTIONS and Use In Specific Populations]. Lactation: Advise patients not to breastfeed while taking Lynparza and for one month after receiving the last dose [see Use In Specific Populations]. Nausea/Vomiting: Advise patients that mild or moderate nausea and/or vomiting is very common in patients receiving Lynparza and that they should contact their healthcare provider who will advise on available antiemetic treatment options. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Carcinogenicity studies have not been conducted with olaparib. Olaparib was clastogenic in an in vitro chromosomal aberration assay in mammalian Chinese hamster (CHO) cells and in an in vivo rat bone marrow micronucleus assay. This clastogenicity is consistent with genomic instability resulting from the primary pharmacology of olaparib and indicates potential for genotoxicity in humans. Olaparib was not mutagenic in a bacterial reverse mutation (Ames) test. In a fertility study, female rats received oral olaparib at doses of 0.05, 0.5, and 15 mg/kg/day for at least 14 days before mating through the first week of pregnancy. There were no adverse effects on mating and fertility rates at doses up to 15 mg/kg/day (maternal systemic exposures approximately 11% of the human exposure (AUC0-24h) at the recommended dose). In a male fertility study, olaparib had no effect on mating and fertility in rats at oral doses up to 40 mg/kg/day following at least 70 days of olaparib treatment (with systemic exposures of approximately 7% of the human exposure (AUC0-24h) at the recommended dose). Use In Specific Populations Pregnancy Risk Summary Based on findings in animals and its mechanism of action [see CLINICAL PHARMACOLOGY], Lynparza can cause fetal harm when administered to a pregnant woman. There are no available data on Lynparza use in pregnant women to inform the drug associated risk. In an animal reproduction study, the administration of olaparib to pregnant rats during the period of organogenesis caused teratogenicity and embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 400 mg twice daily [see Data]. Apprise pregnant women of the potential hazard to the fetus and the potential risk for loss of the pregnancy. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. The estimated background risk in the U.S. general population of major birth defects is 2-4%; and the risk for spontaneous abortion is approximately 15-20% in clinically recognized pregnancies. Data 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 7% 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. Lactation Risk Summary No data are available regarding the presence of olaparib in human milk, or on its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in the breastfed infants from Lynparza, advise a lactating woman not to breastfeed during treatment with Lynparza and for one month after receiving the last dose. Females And Males Of Reproductive Potential Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential prior to initiating treatment with Lynparza. Contraception Females Lynparza can cause fetal harm when administered to a pregnant woman [see Pregnancy]. Advise females of reproductive potential to use highly effective contraception during treatment with Lynparza and for at least 6 months following the last dose. Pediatric Use The safety and efficacy of Lynparza have not been established in pediatric patients. Geriatric Use In clinical studies of Lynparza enrolling 482 patients with advanced solid tumors who received Lynparza tablets 300 mg twice daily as monotherapy, 135 (28%) patients were aged ≥65 years. There appeared to be no major difference in the safety profile of patients treated with olaparib aged <65 years versus ≥65 years, nor within the age categories of 65 to 74 years, 75 to 84 years. No patients were aged ≥85 years. Hepatic Impairment No adjustment to the starting dose is required in patients with mild hepatic impairment. A 15% increase in mean exposure (AUC) was observed in patients with mild hepatic impairment (based on Child-Pugh classification A) compared to patients with normal hepatic function. There are no data in patients with moderate or severe hepatic impairment [see CLINICAL PHARMACOLOGY]. Renal Impairment No adjustment to the starting dose is required in patients with mild renal impairment, but patients should be monitored closely for toxicity. A 24% increase in mean exposure (AUC) was observed in patients with mild renal impairment (CLcr = 51-80 mL/min) compared to patients with normal renal function (CLcr >80 mL/min). A 44% increase in AUC was observed in patients with moderate renal impairment (CLcr = 31-50 mL/min) compared to patients with normal renal function (CLcr >80 mL/min). For patients with moderate renal impairment, reduce the dose of Lynparza capsules to 300 mg twice daily [see DOSAGE AND ADMINISTRATION]. There are no data in patients with severe renal impairment or end-stage disease (CLcr ≤ 30 mL/min) [see CLINICAL PHARMACOLOGY].
