What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This pilot study is testing whether a combination of two dyes (technetium-99m albumin nanocolloid and indocyanine green) can accurately identify the first lymph node where ovarian cancer might spread. The goal is to improve surgical staging and potentially avoid removing many lymph nodes. The study will enroll 62 women with early-stage epithelial ovarian cancer.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Technetium-99m albumin nanocolloid and indocyanine green (ICG)
What this could lead to
If successful, this could lead to a more precise and less invasive way to stage early ovarian cancer, potentially reducing the need for extensive lymph node removal.
What could go wrong
This is a small pilot study (62 participants) focused on diagnostic accuracy, not treatment. The tracers may not detect all affected nodes, and results may not apply to later-stage cancers.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 62 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2023

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with adnexal mass diagnosed with high suspicion of malignancy that will undergo intraoperative biopsy or patients with already diagnosed epithelial cancer in early stages in a previous surgery and confirmed by pathology with complete staging indicated. * Absence of retroperitoneal ganglionary affectation and metastatic disease evaluated by preoperative imaging techniques. * Signing of informed consent by the patient or relative in charge. * Women with childbearing potential must compromise to use highly effective contraceptive methods (partner vasectomized, sexual abstinence) until the end of the study (last study visit). Exclusion Criteria: * Patients \<18 years * Pregnancy or breastfeeding * Epithelial ovarian tumors stage FIGO III or IV. * Impossibility to obtain a biopsy from the tumor. * History of previous vascular surgery (cava vein, aorta, iliac blood vessels) or radiotherapy in pelvic or para-aortic area. * Sentinel lymph node biopsy will not be performed if intraoperative histologic study shows a benign ovarian tumor, low malignancy potential tumor or expansive mucinous histology. * Patient not able to undergo surgery. * Hypersensitivity to active principle, to sodium iodide or iodine allergy. * Patients with clinic hyperthyroidism, thyroid autonomous adenomas or focal and diffused autonomous alteration of thyroid gland
