Key inclusion & exclusion criteria

Inclusion criteria:
?Diagnosis of LGS carcinoma of the ovary, fallopian tube or primary peritoneum (invasive micropapillary serous carcinoma or invasive grade 1 serous carcinoma), confirmed histologically and verified by central pathology review.
?Recurrent or persistent measurable disease that has progressed (defined as radiological and/or clinical progression; an increase in cancer antigen [CA]-125 alone is not sufficient) on or after last therapy (i.e., chemotherapy, hormonal therapy, surgery) and is not amenable to potentially curative intent surgery, as determined by the patient's treating physician.
?Must have received at least 1 prior platinum-based chemotherapy regimen but have received no more than 3 lines of prior chemotherapy regimens, with no limit to the number of lines of prior hormonal therapy.
?Available archival tumor sample (excisional or core biopsy) for confirmation of LGS carcinoma diagnosis. If adequate archival tumor sample is not available, willingness to consent to tissue biopsy.
?Suitable for treatment with at least one of the physician's choice chemotherapy options (liposomal doxorubicin, paclitaxel or topotecan) as determined by the Investigator.
?Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1.
?Other protocol-defined inclusion criteria exist.

?Concomitant malignancies or previous malignancies with less than a 5-year disease-free interval at the time of first dose of study treatment; patients with adequately resected basal or squamous cell carcinoma of the skin, carcinoma in situ of the cervix or ductal carcinoma in situ may be enrolled irrespective of the time of diagnosis.
?Known positive serology for the human immunodeficiency virus (HIV), active hepatitis B and/or active hepatitis C.

Primary Outcome(s)

Secondary Objective: ? Demonstrate superior efficacy (increased OS) of MEK162 vs. physician?s choice of selected chemotherapies
? Obtain additional estimates of the efficacy of MEK162 vs. physician?s choice of selected chemotherapies
? Characterize the safety profile of MEK162 vs. physician?s choice of selected chemotherapies
? Assess the effect on global health status of MEK162 vs. physician?s choice of selected chemotherapies
? Characterize the plasma PK of MEK162 in this patient population

Timepoint(s) of evaluation of this end point: Tumor assessments will be performed every 8 weeks from
randomization for the first 72 weeks, then every 12 weeks while the
patient is receiving study drug treatment, irrespective of the days of study drug administration. Patients who have locally
determined Progressive Disease (PD) confirmed by the BICR will discontinue study drug and cease tumor assessments. Patients who discontinue study drug for reasons other than PD per BICR will continue to have tumor assessments every 8 weeks from randomization for the first 72 weeks, then every 12 weeks for the remainder of the study until one of the following (whichever occurs first): locally determined PD is confirmed by the BICR, withdrawal of consent, initiation of subsequent anticancer therapy, lost to follow-up or death.

Primary end point(s): ? Progression-free survival as determined by the blinded independent central review (BICR). The local Investigator assessments will be used as supportive analyses.

Main Objective: To determine whether treatment with MEK162 prolongs Progression-free survival as compared to physician?s choice of selected chemotherapies (liposomal doxorubicin, paclitaxel and topotecan) in patients with recurrent or persistent low-grade serous carcinomas of the ovary, fallopian tube or primary peritoneum

Secondary Outcome(s)

Secondary end point(s): Key Secondary Endpoint:
? Overall survival
Other Secondary Endpoints:
? Objective response rate as defined by the Response Evaluation Criteria in Solid Tumors (RECIST), Version 1.1
? Duration of response
? Disease control rate (DCR), defined as having achieved a best response of CR or PR, or SD documented at Week 24 or later
? Incidence and severity of AEs, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 4.03
? Changes in clinical laboratory parameters
? Assessment by the QOL questionnaires European Organization for Research and Treatment of Cancer (EORTC) QLQ C30, EORTC QLQ-OV28 and Functional Assessment of Cancer Therapy (FACT)/GOG-Neurotoxicity (NTX)
? Plasma concentration-time profiles and model-based PK parameters of MEK162 (and metabolite AR00426032, if feasible) in a subset of the patients randomized to receive MEK162

Timepoint(s) of evaluation of this end point: Overall Survival: All patients will be followed for survival until withdrawal of consent, lost to follow-up or death; or until the study ends.
ORR, DOR, DCR: Tumor assessments will be performed every 8 weeks from randomization for the first 72 weeks, then every 12 weeks for the remainder of the study
Safety:Continuously while on study drug and for 30 days after the last dose of study drug.
Patient Reported Outcomes: The EORTC QLQ-C30, EORTC QLQ-OV28 and FACT-GOG/NTX questionnaires will be completed within 7 days prior to randomization; every 8 weeks from randomization for the first 72 weeks; at the Treatment Discontinuation Visit;and at the 30-Day Safety Follow-up Visit.
PK:Pharmacokinetic samples will be drawn predose and
2 hours ± 10 minutes postdose on Days 1, 57 and 113.
