What is the purpose of this trial?

This trial examines whether the PINPOINT endoscopic fluorescence imaging system can reduce complications during ovarian cancer surgery. The PINPOINT system uses a glowing dye and a camera to monitor blood flow in real-time, enabling surgeons to address issues immediately. The trial compares surgeries using this system with those using standard methods. Individuals diagnosed with ovarian or related cancers and scheduled for specific types of surgery may be eligible to participate. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the opportunity to contribute to a potentially groundbreaking advancement in surgical care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the PINPOINT imaging system is safe for intra-operative use?

Research has shown that the PINPOINT imaging system aids in surgeries by checking blood flow and reducing complications. This system employs a special camera and glowing dye to allow surgeons to see blood flow in real-time. Studies have found this method useful during surgeries, enabling surgeons to address problems immediately.

Detailed safety information about using the PINPOINT system specifically in ovarian cancer surgery is limited. However, the trial's later stages suggest that earlier studies have demonstrated some level of safety. By this point in research, a treatment has typically been tested on many patients with manageable side effects.

The PINPOINT system is a surgical tool, not a drug, so it functions differently than medications. It does not have the same side effects that drugs might have. Instead, it enhances surgical safety by providing doctors with better information. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment for ovarian cancer?

Researchers are excited about the PINPOINT endoscopic fluorescence imaging system for ovarian cancer surgery because it brings a new level of precision to the operating room. Unlike traditional methods that rely on visual inspection and palpation during surgery, this system uses near-infrared (NIR) angiography to illuminate and assess blood flow in real-time. This can help surgeons identify cancerous tissue more accurately and ensure better perfusion during anastomosis, potentially leading to improved surgical outcomes. By enhancing visualization, this technique aims to reduce complications and improve recovery times, offering a promising advancement over current surgical standards.

What evidence suggests that the PINPOINT imaging system is effective for reducing complications in ovarian cancer surgery?

Research shows that the PINPOINT endoscopic fluorescence imaging system can help reduce complications during ovarian cancer surgery. In this trial, participants in Arm B will receive additional assessment using this system, potentially lowering the risk of unwanted connections between the bowel and other tissues by providing surgeons with a clear, real-time view of blood flow. This enables them to identify and address potential issues immediately. The system uses a special glowing dye to make blood flow visible, which may lead to safer surgeries and better outcomes. Early findings are promising, but more data is needed to confirm these benefits. Participants in Arm A will undergo the standard technique without this imaging system. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for women with ovarian, fallopian tube, or primary peritoneal cancer who are scheduled for surgery to remove the tumor. They must be enrolled before surgery and have a part of their bowel removed that's close to the rectum. Women can't join if they're allergic to ICG dye or need a permanent colostomy.

Inclusion Criteria

I have had surgery to remove part of my lower colon or rectum.

I am scheduled for surgery to remove as much of my cancer as possible.

I have been diagnosed with ovarian, fallopian tube, or peritoneal cancer.

Exclusion Criteria

I need a permanent colostomy.

You have had a bad allergic reaction to ICG before.

I have not had surgery to remove part of my rectum or sigmoid colon.

The PINPOINT Endoscopic Fluorescence Imaging System enhances laparoscopic procedures by providing both conventional white light and near-infrared fluorescence imaging using indocyanine green (ICG), which can improve visualization during surgery.

This high-definition system is designed to aid in the identification of tissues and structures, potentially leading to better surgical outcomes in colorectal procedures.

Fluorescence-guided surgery is a promising technique for improving the visualization of tumors during surgery for epithelial ovarian cancer, allowing for better identification of small tumor masses.

Several targeted fluorescent probes for ovarian cancer are in development, with some imaging devices already demonstrating proof of concept for use in open surgeries, highlighting the potential for clinical application despite existing challenges.
