Phase I Study of a Multivalent WT1 Peptide Vaccine (Galinpepimut-S) in Combination with Nivolumab in Patients with WT1-Expressing Ovarian Cancer in Second or Third Remission.

We examined the safety and immunogenicity of sequential administration of a tetravalent, non-HLA (human leukocyte antigen) restricted, heteroclitic Wilms' Tumor 1 (WT1) peptide vaccine (galinpepimut-S) with anti-PD-1 (programmed cell death protein 1) nivolumab. This open-label, non-randomized phase I study enrolled patients with WT1-expressing ovarian cancer in second or third remission from June 2016 to July 2017. Therapy included six (every two weeks) subcutaneous inoculations of galinpepimut-S vaccine adjuvanted with Montanide, low-dose subcutaneous sargramostim at the injection site, with intravenous nivolumab over 12 weeks, and up to six additional doses until disease progression or toxicity.

Long-term outcomes of patients with recurrent ovarian cancer treated with a polyvalent vaccine with bevacizumab combination.

Background: To characterize the safety, immunogenicity, and outcomes of patients with high-grade serous ovarian cancer (HGSOC) in second or greater remission treated with a polyvalent antigen-KLH plus OPT-821 vaccine construct and bevacizumab.

Methods: Patients with recurrent HGSOC were treated with the vaccine plus bevacizumab at our institution from 01/05/2011 to 03/20/2012. Follow-up continued until 03/2021.

Phase I dose escalation safety and feasibility study of autologous WT1-sensitized T cells for the treatment of patients with recurrent ovarian cancer.

Background: This phase I dose escalation trial evaluated the feasibility of production, safety, maximum tolerated dose, and preliminary efficacy of autologous T cells sensitized with peptides encoding Wilms' tumor protein 1 (WT1) administered alone or following lymphodepleting chemotherapy, in the treatment of patients with recurrent WT1 ovarian, primary peritoneal, or fallopian tube carcinomas.

Methods: A 3+3 dose escalation design was used to determine dose-limiting toxicity (DLT). In cohort I, patients received WT1-sensitized T cells dosed at 5×10/m (level I) without cyclophosphamide lymphodepletion.

A phase 1 dose-escalation study of intraperitoneal cisplatin, intravenous/intraperitoneal paclitaxel, bevacizumab, and olaparib for newly diagnosed ovarian cancer.

Objective: We assessed the safety and maximum tolerated dose (MTD) of the poly ADP-ribose polymerase (PARP) inhibitor olaparib with intravenous (IV)/intraperitoneal (IP) cisplatin/paclitaxel and IV bevacizumab, followed by olaparib and bevacizumab maintenance, in patients with newly diagnosed ovarian cancer who had undergone primary debulking surgery.

Methods: Treatment included: (Cycles 1-6) Day 1, IV paclitaxel 135 mg/m/3 h + (from Cycle 2 onward) bevacizumab 15 mg/kg; Day 2, IP cisplatin 75 mg/m; Days 2-8, olaparib (50/100/200 mg BID); Day 8, IP paclitaxel 60 mg/m of a 21-day cycle. Maintenance (Cycles 7-22) included: olaparib 300 mg BID and bevacizumab 15 mg/kg Day 1.

A Phase I Study of Unimolecular Pentavalent (Globo-H-GM2-sTn-TF-Tn) Immunization of Patients with Epithelial Ovarian, Fallopian Tube, or Peritoneal Cancer in First Remission.

We conducted a phase I study in ovarian cancer patients to evaluate the safety and immunogenicity of a synthetic unimolecular pentavalent carbohydrate vaccine (Globo-H, GM2, sTn, TF, and Tn) supported on a peptide backbone, conjugated to keyhole limpet haemocyanin (KLH), and mixed with immunological adjuvant QS-21. Twenty-four advanced-stage, poor-risk, first-remission ovarian cancer patients were enrolled from January 2011-Septermber 2013. Three dose levels were planned (25, 50, 100 mcg) with three cohorts of six patients each, with an additional 6-patient expansion cohort at the MTD.

Treatment outcomes in completely resected stage I to stage IV uterine carcinosarcoma with rhabdomyosarcoma differentiation.

Objective: To evaluate overall survival (OS) and progression-free survival (PFS) after adjuvant therapy in stage I to stage IV uterine carcinosarcoma with rhabdomyosarcoma differentiation.

Methods: Memorial Sloan-Kettering Cancer Center medical records from 1990 to 2012 were reviewed. Patients who received chemotherapy with or without radiation therapy (RT), or RT alone, for completely resected stage I to stage IV uterine carcinosarcoma with rhabdomyosarcoma differentiation were included.

Eribulin mesylate (halichondrin B analog E7389) in platinum-resistant and platinum-sensitive ovarian cancer: a 2-cohort, phase 2 study.

Background: Eribulin mesylate is a tubulin inhibitor with activity superior to paclitaxel in NIH:OVCAR-3 human epithelial ovarian cancer xenograft models. In this study, the authors assessed the efficacy of eribulin in platinum-resistant and platinum-sensitive recurrent ovarian cancer.

Methods: Patients with recurrent, measurable epithelial ovarian cancer who had received ≤2 prior cytotoxic regimens and who had adequate organ function were enrolled into 2 separate cohorts: 1) platinum-resistant patients (who had a progression-free interval <6 months after their last platinum-based therapy) and 2) platinum-sensitive patients (who had a progression-free interval ≥6 months after their last platinum-based therapy).
