MAMOC is a multicenter, randomized, placebo controlled, double blind study including BRCA negative patients with histologically confirmed, advanced (FIGO stage IIIA, IIIB, IIIC, or IV of the 2014 FIGO classification) high grade serous or high grade endometrioid (based on local histopathological findings) ovarian cancer, fallopian tube cancer, primary peritoneal cancer and clear cell carcinoma of the ovary in first line therapy.


The main scope of this trial is to determine progression free survival in BRCA negative patients treated with Rucaparib as maintenance therapy vs. Placebo after receiving Bevacizumab for 12 to 15 months.

BRCA negative patients will be stratified according to time point of surgery (adjuvant vs. neoadjuvant), result of surgery (tumor free vs. not tumor free resection), study site and response (complete response (CR) vs. partial response (PR)/SD) and randomized 2:1 to receive either Rucaparib (Arm A) or Placebo (Arm B).

In both of the arms, tumor assessments (CT or MRI) are performed before randomization, and every 6 months thereafter.

During treatment, clinical visits (blood cell counts, detection of toxicity) occur every 4 weeks. Physical examinations will take place every 12 weeks. Safety will be monitored continuously by careful monitoring of all adverse events (AEs) and serious adverse events (SAEs).

About 30 sites in Germany will participate in this study to recruit 190 BRCA negative patientsin 24 months.

Yes No Not Sure

Inclusion Criteria

Written informed consent and obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
Age 18
Patients with histologically confirmed, advanced (FIGO stage IIIA, IIIB, IIIC, or IV of the 2014 FIGO classification) high grade serous or high grade endometrioid (based on local histopathological findings) ovarian cancer, fallopian tube cancer, primary peritoneal cancer and clear cell carcinoma of the ovary in first line therapy
Availability of archival tumor tissue for central next-generation sequencing (NGS) Analysis and no Detection BRCA mutation (BRCAnegative)
Treatment with Bevacizumab or respective biosimilar for 12 to 15 months, independent of dosage
Patients who have completed first line platinum-taxane chemotherapy and at least stable disease after treatment with Bevacizumab before randomization
Patients must be randomized at least 3 weeks and no more than 9 weeks after their last dose of Bevacizumab (last dose is the day of the last infusion) and all major toxicities from the previous chemotherapy must have resolved to CTCAE grade 1 or better (except alopecia and peripheral neuropathy)
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
Patients must have normal organ and bone marrow function
Hemoglobin 10.0 g/dL independent of transfusion 14 days prior to Screening hemoglobin assessment
Absolute neutrophil count (ANC) 1.5 x 109 /L
Platelet count 100 x 109 /L
Total bilirubin 1.5 x institutional upper limit of normal (ULN); < 2 ULN if hyperbilirubinemia is due to Gilbert's syndrome
Aspartate aminotransferase /Serum Glutamic Oxaloacetic Transaminase (ASAT/SGOT)) and Alanine aminotransferase /Serum Glutamic Pyruvate Transaminase (ALAT/SGPT)) 3 x ULN, unless liver metastases are present in which case they must be 5 x ULN
Serum creatinine 1.5 x institutional ULN and creatinine clearance > 30 mL/min
Patients not receiving anticoagulant medication who have an International Normalized Ratio (INR) 1.5 and an Activated ProThrombin Time (aPTT) 1.5 x ULN
Postmenopausal or evidence of non-childbearing status for women of childbearing potential prior to the first dose of study treatment. Female patients of childbearing potential must have a negative serum pregnancy test result 3 days prior to administration of the first dose of rucaparib
Patients are considered to be of childbearing potential unless 1 of the
following applies
Considered to be permanently sterile. Permanent sterilization includes hysterectomy, bilateral salpingectomy, and/or bilateral oophorectomy; or
Is postmenopausal, defined as no menses for at least 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level consistently in the postmenopausal range (30 milli International Units/milliliter (mIU/mL) or higher) may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy; however, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient to confirm a postmenopausal state
Female patients of reproductive potential must practice highly effective
methods (failure rate < 1% per year) of contraception with their partners, if
of reproductive potential, during treatment and for 6 months following the
last dose of rucaparib or longer if requested by local authorities. Highly
effective contraception includes: Ongoing use of progesterone only injectable
or implantable contraceptives; Placement of an intrauterine device (IUD) or
intrauterine system (IUS); Bilateral tubal occlusion; Sexual abstinence as
defined as complete or true abstinence, acceptable only when it is the usual
and preferred lifestyle of the patient; periodic abstinence (eg, calendar
symptothermal, post-ovulation methods) is not acceptable; or Sterilization of
the male partner, with appropriate post-vasectomy documentation of absence of
sperm in ejaculate

Exclusion Criteria

Evidence of any other disease, metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or puts the patient at high risk for treatment related complications
