equal to 5 X ULN in the presence of liver metastases)
- creatinine clearance greater than or equal to 51 mL/min (calculated using the
-Cockcroft-Gault formula.
- Pre-clinical data indicate that olaparib can have adverse effects on embryofetal
survival and development. It is further not known whether olaparib or its metabolites
are found in seminal fluid. For these reasons:
- Women of childbearing potential and their partners, who are sexually active, must
agree to the use of 2 highly effective forms of contraception in combination (male
condom plus one other method or must totally/truly abstain from any form of sexual
intercourse. This should be started from the signing of the informed consent,
throughout their participation in the study and for at least 1 month after the last
dose of olaparib.
- Male patients must use a condom during treatment and for 3 months after the last dose
of olaparib when having sexual intercourse with a pregnant woman or with a woman of
childbearing potential. Female partners of male patients should also use a highly
effective form of contraception if they are of childbearing potential. Male patients
should not donate sperm throughout the period of taking olaparib and for 3 months
following the last dose of olaparib.
- Acceptable birth control methods:
- Total sexual abstinence i.e., refrain from any form of sexual intercourse in line
with the patients usual and/or preferred lifestyle. Abstinence must be for the
total duration of the study treatment and for at least 1 month (for female
patients) or 3 months (for male patients) after the last dose of study treatment.
Periodic abstinence (e.g., calendar ovulation, symptothermal, post-ovulation
methods) and withdrawal are not acceptable methods of contraception.
- Vasectomised sexual partner PLUS male condom. With participant assurance that
partner received post-vasectomy confirmation of azoospermia.
- Tubal occlusion PLUS male condom
- Intrauterine Device PLUS male condom. Provided coils are copper-banded.
- Etonogestrel implants (e.g., Implanon, Norplant) PLUS male condom
- Normal and low dose combined oral pills PLUS male condom
- Hormonal shot or injection (e.g., Depo-Provera) PLUS male condom
- Intrauterine system device (e.g., levonorgestrel-releasing intrauterine system
-Mirena) PLUS male condom
- Norelgestromin/ethinyl estradiol transdermal system PLUS male condom
- Intravaginal device (e.g., ethinyl estradiol and etonogestrel) PLUS male condom
- Cerazette (desogestrel) PLUS male condom. Cerazette is currently the only highly
efficacious progesterone based pill.
- Ability of subject to understand and the willingness to sign a written informed
consent document.
EXCLUSION CRITERIA:
- Patients who are receiving any other investigational agents.
- Patients who have received any previous treatment with a Poly (ADP-ribose) polymerase
(PARP) inhibitor, including olaparib.
- Patients receiving any systemic chemotherapy or radiotherapy (except for palliative
reasons) within 3 weeks prior to study treatment
- Patients with other malignancy documented as occurring within the last 1 year except:
adequately treated nonmelanoma skin cancer, curatively treated in situ cancer of the
cervix, ductal carcinoma in situ (DCIS), Stage 1, grade 1 endometrial carcinoma, or
other solid tumors including lymphomas (without bone marrow involvement) documented as
curatively treated or under control for greater than or equal to 1 year.
- Patients with features suggestive of Myelodysplastic syndromes (MDS) and acute myeloid
leukemia (AML) on peripheral blood smear.
- Patients with symptomatic uncontrolled brain metastases. A scan to confirm the absence
of brain metastases is not required. The patient can receive a stable dose of
corticosteroids before and during the study as long as these were started at least 4
weeks prior to treatment. Patients with spinal cord compression unless considered to
have received definitive treatment for this and evidence of clinically stable disease
for 28 days.
- History of allergic reactions or hypersensitivity attributed to compounds of similar
chemical or biologic composition to olaparib or its excipients.
- Patients who have had a whole blood transfusion within 120 days prior to enrollment.
(Packed red blood cells and platelet transfusions are acceptable)
- Patients with persistent toxicities (greater than or equal to Common Terminology
Criteria for Adverse Events (CTCAE) grade 2) with the exception of alopecia,caused by
previous cancer therapy
- Concomitant use of known strong or moderate cytochrome P450, family 3 (CYP3A)
inhibitors (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors
boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir,
telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem,
fluconazole, verapamil). The required washout period prior to starting olaparib is 2
weeks.
- Concomitant use of known strong CYP3A inducers (e.g. phenobarbital, enzalutamide,
phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's
Wort) or moderate CYP3A inducers (e.g. bosentan, efavirenz, modafinil). The required
washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital
and 3 weeks for other agents.
- Resting electrocardiogram (ECG) with Fridericia's formula (QTcF) > 470 msec on 2 or
more time points within a 24-hour period or family history of long Q wave, T wave (QT)
syndrome
- Patients that have had major surgery within 2 weeks of starting study treatment and
patients must have recovered from any effects of any major surgery.
- Patients unable to swallow orally administered medication and patients with
gastrointestinal disorders likely to interfere with absorption of the study
medication.
- Patients considered a poor medical risk due to a serious, uncontrolled medical
disorder, non-malignant systemic disease or active, uncontrolled infection. Examples
include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3
months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal
cord compression, superior vena cava syndrome, extensive interstitial bilateral lung
disease on High Resolution Computed Tomography (HRCT) scan or any psychiatric disorder
that prohibits obtaining informed consent.
- Pregnant women are excluded from this study because olaparib has the potential for
teratogenic or abortifacient effects. Women must either be post-menopausal or must
have a negative pregnancy test (urine or serum) less than or equal to 28 days prior to
enrollment and confirmed on day 1 of cycle 1 of study therapy. Postmenopausal is
defined as:
Amenorrheic for 1 year or more following cessation of exogenous hormonaltreatments
Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels in the
post-menopausal range for women under 50 years of age
radiation-induced oophorectomy with last menses >1 year ago
chemotherapy-induced menopause with >1-year interval since last menses
surgical sterilisation (bilateral oophorectomy or hysterectomy)
- Because there is an unknown but potential risk for adverse events in nursing infants
secondary to treatment of the mother with olaparib, breastfeeding should be
discontinued if the mother is treated with olaparib.
- Immunocompromised patients are excluded.
- Patients who are known to be serologically positive for human immunodeficiency virus
(HIV). This includes HIV patients on antiretroviral therapy due to the potential for
pharmacokinetic interactions with olaparib.
- Patients with known active hepatitis (i.e. Hepatitis B or C) due to risk of
transmitting the infection through blood or other body fluids
- Previous allogeneic hematopoietic stem cell transplant, allogeneic bone marrow
transplant or double umbilical cord blood transplant (duCBT)
