Ovarian Reserve After Cancer: Longitudinal Effects (ORACLE)

October 27, 2025 updated by: University of Pennsylvania

Ovarian Reserve After Cancer: Longitudinal Effects A Multicenter Prospective Cohort Study by the Oncofertility Consortium

Women of reproductive age who will receive treatment for cancer that includes chemotherapy may participate in a study measuring ovarian function over time. Eligible women are asked to complete a questionnaire, a menstrual diary, a brief physical examination, an ultrasound, and a blood test before, during and after cancer treatment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

A total of 7 study visits will be completed at 3 month intervals including 1 visit prior to treatment, and at least 2 visits after completion of treatment. Duration of study participation is 18-30 months, depending on length of treatment.

Review and Documentation of Cancer Therapy will be abstracted from the clinical oncology chart by the oncology offices caring for the patient. Treatment will be summarized in terms of chemotherapeutic type, duration and cumulative dose; total radiation dose and location; history and type of bone marrow transplantation; and any surgery. Any attempts at fertility preservation or use of gonadotropin releasing hormone agonist treatment during cancer therapy will be captured as well.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

11 years to 35 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Postmenarchal females, ages 11-35, who will require chemotherapy; An unexposed cohort balanced to the exposed cohort with respect to age and oral contraceptive use.

Description

Inclusion Criteria for exposed population:

  • Postmenarchal females to be treated with chemotherapy
  • between the ages of 11-35 years,
  • with a uterus and at least one ovary

Inclusion Criteria for unexposed population:

  • healthy postmenarchal females
  • no prior or planned exposure to chemotherapy
  • between the ages of 11-35,
  • with a uterus and at least one ovary
  • regular menstrual cycles (21-35 days)

Exclusion criteria for all subjects:

  • positive pregnancy test at enrollment
  • lactation within the previous 1 month,
  • previous treatment with chemotherapy or radiation therapy with the exception of radioactive iodine for thyroid cancer.
  • previous diagnosis of an illness associated with premature ovarian failure (Turner's syndrome, Fragile X permutation carrier)
  • endocrine disorder associated with irregular menstrual cycles (Cushing's disease, Thyroid disease, hyper-prolactinemia, congenital adrenal hyperplasia).

Additional exclusions for the unexposed population:

  • a history of infertility, defined as at least 12 months of unprotected intercourse without conception
  • polycystic ovary syndrome (PCOS)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline in reproductive hormone measures, during and after chemotherapy.
Time Frame: 18-30 months: pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
20 mls blood will be obtained at stated timepoints for determining levels of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Estradiol (E2), Inhibin B, and Anti-mullerian Hormone (AMH). In menstruating girls and young women hormone measures will be obtained during the early follicular phase of the menstrual cycle (days 1-4). In women with irregular cycles the testing will be done spontaneously without regard for the bleeding pattern.
18-30 months: pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline in antral follicle counts, during and after chemotherapy.
Time Frame: 18-30 months: pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
All ovarian follicles and cysts will be measured by transvaginal or transabdominal ultrasound. Follicles will be measured in millimeters and grouped according to size: 2-5 mm, 6-9 mm, and >10 mm in diameter.
18-30 months: pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline in menstrual function, during and after chemotherapy
Time Frame: 18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
Subjects are asked to document menstrual bleeding in a diary, noting duration of each menstrual period in days, bleeding intensity (spotting, light, moderate, heavy, flooding, none), and intervals between periods.
18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
Change from baseline in menopausal symptoms during and after chemotherapy.
Time Frame: 18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
The validated "Menopausal Symptom List" (MSL) will be used at each study visit to assess the presence or absence of menopausal symptoms during the past month, the frequency and severity of each symptom. Symptoms captured include: hot flashes, vaginal dryness, concentration/memory problems, irritability, mood swings, feeling sad, feeling anxious, trouble sleeping, aches, joint pain, headaches.
18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
Change from baseline in ovarian volume during and after chemotherapy.
Time Frame: 18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
Ovaries will be measured in three dimensions. Uterine size and endometrial thickness will also be performed. The transvaginal approach is preferred, but transabdominal ultrasound will be performed in girls who do not feel comfortable with the transvaginal procedure.
18-30 months: Pre-chemotherapy baseline and at 3 month intervals from start of chemotherapy through 6 months after end of chemotherapy.
