DUO-O Trial Summary

This trial is testing a new combination of drugs for ovarian cancer. The goal is to see if it is more effective and has fewer side effects than the current standard of care.

Who is the study for?
This trial is for women over 18 with newly diagnosed advanced ovarian cancer, including certain subtypes and related cancers. They should be fit for surgery, have a performance status of 0-1 indicating they are fully active or restricted in physically strenuous activity but ambulatory, and not pregnant. Exclusions include autoimmune disorders, brain metastases, recent malignancies except specific treated cases, ongoing severe side effects from past treatments, cardiovascular disease, prior treatment for ovarian cancer or allergies to the study drugs.Check my eligibility
What is being tested?
The study tests Durvalumab combined with chemotherapy (Carboplatin+Paclitaxel) and Bevacizumab versus placebo controls followed by maintenance therapy with Durvalumab and Bevacizumab alone or alongside Olaparib. It's a Phase III trial where patients are randomly assigned to different treatment groups without knowing which one they're receiving.See study design
What are the potential side effects?
Possible side effects include immune-related reactions due to Durvalumab affecting organs like lungs or intestines; high blood pressure from Bevacizumab; bone marrow suppression causing low blood cell counts from chemotherapy; fatigue; nausea; potential allergic reactions to any drug components.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are patients being accepted for this research project at present?

"The trial, which was last updated on October 5th, 2022 and originally posted on January 4th, 2019 according to clinicaltrials.gov, is currently looking for participants."

Answered by AI

Does this research involve people who are over 40 years old?

"In order to be included in this trial, patients must between the ages of 18-130. There are 129 other trials for those under 18 and 2371 for people 65 and older."

Answered by AI

For what sorts of medical conditions is Bevacizumab typically prescribed?

"Bevacizumab is frequently used to treat malignant neoplasms, but it can also be useful in treating locally advanced nonsquamous non-small cell lung cancer, metastatic colorectal cancer (crc), and as part of a conditioning regimen for allogeneic stem cell transplantation therapy."

Answered by AI

Has Bevacizumab been cleared for use in the United States?

"According to our assessment, Bevacizumab ranks as a 3 in terms of safety. This is because it has reached Phase 3 clinical trials, meaning that there is both supportive efficacy data and multiple rounds worth of data affirming its safety."

Answered by AI

What are the prerequisites for participating in this clinical trial?

"This study is accepting 1374 patients with ovary cancer aged 18 and 130. Most notable, applicants should meet the following criteria: Patients must be aged ≥18 years of age. For patients enrolled in Japan that are aged <20 year, Female patients with newly diagnosed, histologically confirmed, advanced (Stage III-IV) high grade epithelial ovarian cancer including high grade serious, high grade endometriod, clear cell ovarian cancer or carcinosarcoma, primary peritoneal cancer and / or fallopian-tube cancer, All patients should be candidates for cytoreductive surgery either: upfront primary surgery OR plan"

Answered by AI

What goals does this research hope to achieve?

"The aim of this long-running clinical trial is to study the impact of durvalumab on progression-free survival (PFS) in non-tBRCA HRD positive patients. Additionally, researchers will investigate if there is an increased benefit for tBRCAm patients and look at objective response rates (ORR) in non-tBRCAm patients."
