Paclitaxel With or Without Viral Therapy in Treating Patients With Recurrent or Persistent Ovarian Epithelial, Fallopian Tube, or Primary Peritoneal Cancer

PRIMARY OBJECTIVES:

I. To estimate the progression-free survival hazard ratio of the combination of weekly
paclitaxel with Reolysin (wild-type reovirus) to weekly paclitaxel alone in patients with
persistent or recurrent ovarian, fallopian tube, or primary peritoneal cancer.

II. To determine the frequency and severity of adverse events associated with treatment with
weekly paclitaxel alone and weekly paclitaxel with REOLYSIN as assessed by Common Terminology
Criteria for Adverse Events (CTCAE).

SECONDARY OBJECTIVES:

I. To estimate the progression-free survival and overall survival of patients treated with
weekly paclitaxel alone and weekly paclitaxel with REOLYSIN.

II. To estimate (and compare) the proportion of patients who respond to the regimen on each
arm of the study (according to Response Evaluation Criteria in Solid Tumors [RECIST] 1.1 with
measurable patients and by cancer antigen [CA]-125 for those patients with detectable disease
only).

III. To characterize and compare progression-free survival and overall survival in patients
with measurable disease (RECIST 1.1 criteria) and patients with detectable (non-measurable)
disease.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15.

ARM II: Patients receive paclitaxel as in arm I and wild-type reovirus IV over 1 hour on days
1-5.

In both arms, treatment repeats every 28 days in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and
then every 6 months for 3 years.

Inclusion Criteria:

- Patients must have recurrent or persistent epithelial ovarian, fallopian tube or
primary peritoneal carcinoma; histologic documentation of the original primary tumor
is required via the pathology report

- Patients must have measurable disease or detectable (non-measurable) disease:

- Measurable disease is defined as at least one lesion that can be accurately
measured in at least one dimension (longest diameter to be recorded); each lesion
must be >= 10 mm when measured by computed tomography [CT], magnetic resonance
imaging [MRI] or caliper measurement by clinical exam; or >= 20 mm when measured
by chest x-ray; lymph nodes must be > 15 mm in short axis when measured by CT or
MRI

- Detectable (non-measurable) disease is defined as not having measurable disease
but has at least one of the following conditions:

- Baseline values of CA-125 at least 2 x upper limit of normal (ULN);

- Ascites and/or pleural effusion attributed to tumor;

- Solid and/or cystic abnormalities on radiographic imaging that do not meet
RECIST 1.1 definitions for target lesions

- Patient with measurable disease must have at least one "target lesion" to be used to
assess response on this protocol as defined by RECIST 1.1; tumors within a previously
irradiated field will be designated as "non-target" lesions unless progression is
documented or a biopsy is obtained to confirm persistence at least 90 days following
completion of radiation therapy

- Patients must not be eligible for a higher priority Gynecologic Oncology Group (GOG)
protocol, if one exists; in general, this would refer to any active GOG phase III
protocol or rare tumor protocol for the same patient population

- Patients who have received one prior regimen must have a GOG performance status of 0,
1, or 2

- Patients who have received two or three prior regimens must have a GOG
performance status of 0 or 1

- Recovery from effects of recent surgery, radiotherapy, or chemotherapy:

- Patients should be free of active infection requiring antibiotics (with the
exception of uncomplicated urinary tract infection [UTI])

- Any hormonal therapy directed at the malignant tumor must be discontinued at
least one week prior to registration; continuation of hormone replacement therapy
is permitted

- Any other prior therapy directed at the malignant tumor, including chemotherapy,
biologic/targeted and immunologic agents, must be discontinued at least three
weeks prior to registration

- Patients must have had one prior platinum-based chemotherapeutic regimen for
management of primary disease containing carboplatin, cisplatin, or another
organoplatinum compound; this initial treatment may have included intraperitoneal
therapy, consolidation, non-cytotoxic agents (biologic/targeted) or extended therapy
administered after surgical or non-surgical assessment; if patients were treated with
paclitaxel for their primary disease, this can have been given weekly or every 3 weeks

- Patients are allowed to receive, but are not required to receive, two additional
cytotoxic regimens for management of recurrent or persistent disease, with no more
than 1 non-platinum, non-taxane regimen; treatment with weekly paclitaxel for
recurrent or persistent disease is NOT allowed

- Patients are allowed to receive, but are not required to receive, non-cytotoxic
(biologic/targeted) therapy as part of their primary treatment regimen; patients are
allowed to receive, but are not required to receive, non-cytotoxic (biologic/targeted)
therapy as part of their treatment for recurrent or persistent disease and/or as
treatment for recurrent or persistent disease; if non-cytotoxic (biologic/targeted)
therapy is given alone (i.e., not in combination with cytotoxic chemotherapy) it will
NOT count as a prior regimen

- For the purposes of this study, poly (adenosine diphosphate [ADP]-ribose)
polymerase (PARP) inhibitors will NOT count as a prior regimen when given alone
(i.e., not in combination with cytotoxic chemotherapy)

- Patients who have received only one prior cytotoxic regimen (platinum-based regimen
for management of primary disease), must have a platinum-free interval of less than 12
months, or have progressed during platinum-based therapy, or have persistent disease
after a platinum-based therapy
