PHASE2

Intensive Locoregional Chemoimmunotherapy, Intradermal Autologous Alpha-DC1 Vaccines, and Systemic Pembrolizumab for Advanced-Stage Ovarian Cancer

Sponsor: Kalinski, Pawel, MD, PhD

View on ClinicalTrials.gov

Summary

This trial proposes to evaluate the immunologic and potential clinical effectiveness of intensive locoregional sequential intraperitoneal (IP) cisplatin (IPC) with intravenous (iv) paclitaxel followed by peritoneal infusion of a chemokine modulatory (CKM) regimen composed of a cocktail of IP rintatolimod and interferon-alpha (IFNα) for patients with advanced stage ovarian cancer (III-IV) in the primary neoadjuvant setting. It was previously determined the tolerable dose of IPC-CKM. This study will add intradermal (ID) autologous αDC1 vaccines (known to be nontoxic) to the tolerable IPC-CKM regimen and systemic Keytruda (pembrolizumab). To optimize the pattern of immunity, all patients will also receive oral celecoxib (COX2 inhibitor).

Conditions

Interventions

DRUG

Paclitaxel

A chemotherapy for cancer patients that interferes structures that help move chromosomes during cell division, thus stabilizing these structures to prevents cancer cells from dividing and ultimately causing them to die. Dose: 175 mg/m\^2 IV on D1 each cycle during neoadjuvant and adjuvant periods.

DRUG

Cisplatin

An alkylating agent that contains platinum, which binds to DNA in cancer cells, causing cross-links that prevent DNA replication and repair, leading to cell death, particularly in rapidly dividing cancer cells. Dose: 75 mg/m\^2 IP / 1 hour on D1 of each cycle during neoadjuvant and adjuvant treatment periods.

DRUG

Bioferon

Inhibits replication of a wide range of RNA and DNA viruses and exerts antiproliferative effects on malignant cells. It suppresses antibody formation through an effect on B-lymphocytes and inhibits onset of delayed hypersensitivity. Dose:6 milli on units/100 mL IP over 30-60 minutes on D2 of each cycle during neoadjuvant and adjuvant treatment. D1 during maintenance treatment periods.

DRUG

Rintatolimod

A synthetic double-stranded RNA that selectively activates Toll-like Receptor 3 (TLR3), triggering antiviral and immunomodulatory responses, priming the immune system without causing excessive inflammation. Dose: 200 mg IP over 1-2 hours on D2 of each cycle during the neoadjuvant and adjuvant treatment periods. D1 during maintenance treatment periods

BIOLOGICAL

αDC1 Vaccine

Autologous tumor-loaded alpha-DC1 vaccine is the new type of dendritic cell vaccine developed by our group, are the serum-free, clinically-applicable version of type-1 polarized DCs, combining a fully-mature phenotype and high expression of co-stimulatory molecules with an elevated, rather than exhausted, ability to produce IL-12p70. Dose: 6 million dendritic cells (reduced or omitted if insufficient vaccine material), ID injection on rotating sides of lower extremities on D2 each cycle during the neoadjuvant (not C1) and adjuvant treatment periods. D1 of each cycle during maintenance period.

DRUG

Pembrolizumab

Humanized monoclonal antibody and a PD-1 inhibitor used in cancer immunotherapy that differs from chemotherapy as it does not directly kill cancer cells but stimulates the immune system, particularly T-cells, to recognize and attack cancer cells more effectively. Dose: 200 mg IV / 30 minutes on D2 of each cycle during neoadjuvant treatment period (none last neoadjuvant cycle), then optional on D2 for adjuvant treatment cycles, and on D1 of maintenance cycles

DRUG

Celecoxib

A COX-2 inhibitor in the class of nonsteroidal anti-inflammatory drugs (NSAIDs) that specifically target the cyclooxygenase-2 (COX-2) enzyme, which plays a key role in inflammation Dose: 200mg/day, orally twice a day for days 1-5 and once a day for days 6-21 of neoadjuvant and adjuvant treatment cycles, and then twice a day on D1 and once a day for days 2-21 for maintenance cycles

PROCEDURE

Debulking Procedure

A surgical procedure designed to remove the majority of cancerous tumors when complete removal may not be feasible, with the goal of reducing tumor burden, making follow-up treatments like chemotherapy or radiation more effective. Surgery occurs in between the neoadjuvant and adjuvant treatment periods.
