Description:
This phase II trial studies the side effects of ONC201 and paclitaxel and how well they work
in treating patients with platinum-resistant epithelial ovarian, fallopian tube, or primary
peritoneal cancer that has come back (recurrent), or that does not respond to treatment
(refractory). ONC201 is the first in its class of drugs that antagonize some specific cell
receptors on cancer cells, leading to their destruction. Drugs used in chemotherapy, such as
paclitaxel, work in different ways to stop the growth of cancer cells, either by killing the
cells, by stopping them from dividing, or by stopping them from spreading. Giving ONC201 and
paclitaxel may work better in treating patients with platinum-resistant epithelial ovarian,
fallopian tube, or primary peritoneal cancer compared to paclitaxel alone.

(refractory). ONC201 is the first in its class of drugs that antagonize some specific cell

Detailed Description
PRIMARY OBJECTIVES:
I. To evaluate the safety and tolerability of the combination of Akt/ERK inhibitor ONC 201
(ONC201) and paclitaxel in patients with platinum refractory or resistant epithelial ovarian,
fallopian tube or primary peritoneal cancer. (Part 1) II. To evaluate the objective response
rate (ORR) of ONC201 in combination with paclitaxel in patients with platinum refractory or
resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer. (Part 2) III. To
evaluate progression free survival (PFS) of ONC201 in combination with weekly paclitaxel in
patients with platinum refractory or resistant epithelial ovarian, fallopian tube or primary
peritoneal cancer. (Part 2)
SECONDARY OBJECTIVES:
I. To evaluate the durability/duration of response (DOR) of ONC201 in combination with
paclitaxel.
II. To evaluate the safety and patient reported tolerability of ONC201 in combination with
paclitaxel. (Part 2) III. To evaluate the disease control rate (DCR) of ONC201 in combination
with paclitaxel.
IV. To evaluate the cancer antigen-125 (CA-125) and/or human epididymis factor 4 (HE-4)
response of ONC201 in combination with paclitaxel in those patients with one or both of these
tumor markers upregulated.
V. To characterize the pharmacokinetics (PK) and pharmacodynamics (PD) of ONC201 in
combination with paclitaxel.
VI. To obtain preliminary estimates of overall survival (OS) of ONC201 in combination with
weekly paclitaxel.
EXPLORATORY OBJECTIVES:
I. To evaluate the immune response (specifically natural killer [NK] cell and cytokine
profile) of ONC201 in combination with paclitaxel in patients with platinum refractory or
resistant epithelial ovarian, fallopian tube or primary peritoneal cancer.
OUTLINE:
Patients receive ONC201 orally (PO) on days 1, 8, and 15, and paclitaxel intravenously (IV)
over 1 hour on days 2, 9, and 16. Cycles repeat every 28 days in the absence disease
progression or unacceptable toxicity. If paclitaxel must be stopped for any reason, patients
may continue on ONC201 alone.
After completion of study treatment, patients are followed up for 1 year.
