Study population: Study participants will be pre- and post-pubertal females 8 years and older greater seen at the University of Colorado Anschutz Pavilion and/or Children's Hospital Colorado who have received gonadotoxic chemotherapy; radiation; or surgical excision of a reproductive organ for malignancy. The anticipated study population for Group B will be approximately 3,338 per year for five years for an projected total of 16, 690. Group A will have an anticipated study population of 3,338 per year for three years for an projected total of 10,014. For Groups A and B that is a grand total of 26,704.

About this study

This is an observational cohort study to examine the use of a novel proposed ovarian reserve monitoring algorithm to (1) identify patients who are at risk of DOR and POI from gonadotoxic therapy, (2) minimize time from treatment to utilization of assisted reproductive technologies, and (3) improves prognosis for successful ART based on AFC for patients who pursue fertility or fertility preservation.

Read the detailed description

Study Design: This is an observational cohort study to examine the use of a novel proposed ovarian reserve monitoring algorithm to (1) identify patients who are at risk of DOR and POI from gonadotoxic therapy, (2) minimize time from treatment to utilization of assisted reproductive technologies, and (3) improves prognosis for successful ART based on AFC for patients who pursue fertility or fertility preservation.

Group B: Prospectively, survivors will be evaluated by a member of the FPRLE team in the outpatient clinic at 12 months post-therapy completion and every 6 months to 36 months as part of clinical care. AMH and FSH will be drawn at each time point.

Group A: Retrospectively, we will abstract AMH and FSH from survivors seen at CHCO and UCH from October 1st, 2016 to September 31st, 2019 and assess time points.

Approach Aim 1: The Investigator will assess AMH and FSH in both groups and evaluate whether the monitoring algorithm allows for early identification of DOR prior to the occurrence of POI. The investigator will calculate time from end of treatment to diagnosis of DOR and POI to evaluate if the monitoring algorithm detects these conditions earlier than historical controls.

Statistical analysis: The investigator will provide descriptive statistics and time to event analysis by group.

Aim 2: The Investigator will assess time from end of treatment to utilization of ART as defined by ovulation induction with or without insemination, in vitro fertilization, and/or third-party reproduction.

Statistical analysis: The Investigator will provide descriptive statistics and time to event analysis by group (A and B).

Aim 3: The Investigator will assess if early identification of DOR improves prognosis for successful ART for Group B as compared to Group A. The Investigator define success as an AFC greater than or equal to 6 at time of evaluation by REI.

Statistical analysis: The Investigator will provide descriptive statistics for the prevalence of AFC greater than 6 by group (A and B).

Aim 4: The Investigator will characterize barriers to utilization of ART by surveying participants who were referred to REI. The Investigator will assess the following: (1) if participants declined or accepted referral, (2) if they accepted, were they successful, and (3) if they declined, reasons for declining.

Study groups in NCT05048654
Study groupRoleWhat they receive
Group A: RetrospectiveRetrospectively, there will be an abstract of AMH and FSH from survivors seen at CHCO and UCH from October 1st, 2016 to September 31st, 2019 and assess time points.
Group B: ProspectiveProspectively, survivors will be evaluated by a member of the FPRLE team in the outpatient clinic at 12 months post-therapy completion and every 6 months to 36 months as part of clinical care. Per standard of care AMH and FSH will be drawn at each time point.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Does the novel monitoring algorithm (intervention group) detect early Ovarian disfunction

    We will compare ovarian reserve categories (normal, diminished ovarian reserve, primary ovarian insufficiency), defined using AMH and FSH, in a retrospective group using the standard of care and a prospective group using a new monitoring algorithm.

    Measured: 2 year follow up

Secondary outcomes (3)
  1. Time to ART

    Assess if the length of time from end of treatment to utilization of ART is different between the two groups.

    Measured: 2 year follow up

  2. Evaluate if there is an improved AFC in the new monitoring algorithm group

    Assess if the proportion of AFC greater than or equal to 6 at time of evaluation by REI is higher in the new monitoring algorithm group compared to the standard of care.

    Measured: 2 year follow up

  3. Characterizing barriers to utilization of ART

    We will examine the following: (1) if participants declined or accepted referral, (2) if they accepted, were they successful, and (3) if they declined, reasons for declining.

    Measured: 2 year year follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Ovarian Diseases and Fertility Issues, run by University of Colorado, Denver.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 18 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Does the novel monitoring algorithm (intervention group) detect early Ovarian disfunction (time frame: 2 year follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2025.
