NCT ID NCT06214936

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether a benchtop incubator helps more embryos reach the blastocyst stage compared to a standard box incubator in people undergoing IVF. 252 participants will have their eggs split and placed in both incubators. The goal is to see which device supports better embryo development.

What this could mean

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

What this could lead to
If benchtop incubators prove better, IVF labs may adopt them to improve embryo development rates.
What could go wrong
This is a small, early-stage study focused on lab outcomes, not pregnancy success. Results may not change clinical practice.

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 252 people

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

Started

Dec 2023

Expected to finish

Jul 2027

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 to 41 years

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 for participants: 1. Patients undergoing an IVF cycle with plan for subsequent frozen embryo transfer (FET) of a single euploid embryo 2. 4 mature oocytes prior to randomization 3. Female partners age \<42 years old at start of their vaginal oocyte retrieval (VOR) cycle 4. Normal ovarian reserve: 1. Antimullerian Hormone Level (AMH) ≥ 1.2 ng/mL 2. Antral Follicle Count (AFC) ≥ 8 3. Follicle Stimulating Hormone (FSH) FSH ≤ 12international units (IU)/L 5. Body Mass Index (BMI) \<35 6. Patients who desire to transfer the best quality embryo for their embryo transfer. However, if a participant ends up electing to transfer based on sex preference after enrollment these outcomes will still be followed and included in the intention to treat analysis. Exclusion Criteria for participants: 1. All patients who do not voluntarily give their written consent for participation 2. Patients with a prior failed IVF cycle - defined as no blastocysts 3. Patients with a history of more than one failed euploid embryo transfer 4. Donor oocyte cycles 5. Gestational Carriers 6. Male partner with \<100,000 total motile spermatozoa per ejaculate (donor sperm is acceptable) 7. Use of surgical procedures to obtain sperm 8. Communicating hydrosalpinges without a plan for surgical correct prior to frozen embryo transfer 9. Endometrial Insufficiency, as defined by a prior cycle with maximal endometrial thickness \<6mm,), or persistent endometrial fluid 10. Single gene disorders, chromosomal translocations, or any other disorders requiring a more detailed embryo genetic analysis
