I. To determine the maximum tolerated doses (MTD) and dose limiting toxicities (DLTs) of VTX-2337 when administered in combination with pegylated liposomal doxorubicin (PLD; Doxil, Lipodox™) 40 mg/m2 in Regimen 1 and when administered in combination with weekly paclitaxel 80 mg/m2 in Regimen 2, and the associated DLTs based on adverse events that occur in cycle 1 for each of these combinations in women with recurrent or persistent, epithelial ovarian, fallopian tube or primary peritoneal cancer.
II. To examine the tolerability of the combination at the MTD of VTX-2337 assessed in combination with PLD 40 mg/m2 and with PLD 50 mg/m2 in Regimen 1 and in combination with weekly paclitaxel in Regimen 2.
III. To determine recommended phase II doses (RP2D) of VTX-2337 in combination with PLD in Regimen 1 and in combination with weekly paclitaxel in Regimen 2.
I. To assess the biological effects (immune activation) of VTX-2337 in combination with PLD in Regimen 1 and in combination with weekly paclitaxel in Regimen 2.
II. To assess the pharmacokinetics in patients receiving VTX-2337 in combination with PLD in Regimen 1 and in combination with weekly paclitaxel in Regimen 2.
III. To assess the tolerability (including CTCAE v4 Grade 3/4 allergic reaction) of weekly paclitaxel 80 mg/m2 when administered without corticosteroid premedication (Regimen 2 only).
I. To assess the anti-tumor activity of VTX-2337 when administered concomitantly with PLD in Regimen 1 and when administered concomitantly with weekly paclitaxel in Regimen 2 in patients with recurrent or persistent epithelial ovarian fallopian tube or primary peritoneal cancer.
II. To assess the effect of TLR8 polymorphisms on the biological (immune) and clinical effects of VTX-2337 in combination with PLD in Regimen 1 and in combination with weekly paclitaxel in Regimen 2.
OUTLINE: This is a multicenter, dose-escalation study.
Patients receive TLR8 agonist VTX-2337 subcutaneously (SC) on days 3, 10, and 17 and pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1 or TLR8 agonist VTX-2337 subcutaneously on days 1, 8, and 15 and paclitaxel IV over 60 minutes on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Blood samples are collected periodically during courses 1 and 2 for pharmacokinetic, pharmacogenomic, and other research studies. After completion of study treatment, patients are followed up every 3 months for 1 year.

Experimental: Treatment (TLR8 agonist VTX-2337, PLD, and Paclitaxel)
Patients receive TLR8 agonist VTX-2337 SC on days 3, 10, and 17 and pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1 or TLR8 agonist VTX-2337 SC on days 1, 8, and 15 and paclitaxel IV over 60 minutes on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
