Frequently asked questions about Oregovomab

What is Oregovomab used for in ovarian cancer?

Oregovomab is an investigational monoclonal antibody being studied for the treatment of advanced epithelial ovarian cancer. It is being evaluated in newly diagnosed patients following optimal debulking surgery, in combination with chemotherapy. The drug targets MUC16, a tumor-associated antigen expressed on ovarian cancer cells.

What does Oregovomab target?

Oregovomab targets MUC16, a cell surface glycoprotein also known as CA-125, which is highly expressed on ovarian cancer cells. By binding to MUC16, the antibody is designed to elicit an immune response against the tumor. This mechanism is being investigated in the context of advanced epithelial ovarian cancer.

Who is developing Oregovomab?

Oregovomab is being developed by IQVIA Holdings, Inc., a company publicly traded under the ticker symbol IQV. The drug is currently in Phase 3 clinical development for the treatment of advanced epithelial ovarian cancer.

What phase is Oregovomab in?

Oregovomab is currently in Phase 3 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 3 trial is evaluating its efficacy and safety in patients with newly diagnosed advanced epithelial ovarian cancer.

What clinical trials is Oregovomab in?

Oregovomab is being studied in a single Phase 3 clinical trial registered as NCT04498117. This randomized, double-blind, placebo-controlled trial enrolls approximately 615 female patients aged 18 years and older with newly diagnosed advanced epithelial ovarian cancer following optimal debulking surgery. The trial is active but not recruiting participants.

Is Oregovomab the same as any other drug?

Oregovomab is a distinct monoclonal antibody with the ChEMBL identifier CHEMBL2107917. No alternative names for this drug have been reported in the available clinical trial information. It is being studied specifically for its potential role in treating advanced epithelial ovarian cancer.
