Triptorelin for the Prevention of Ovarian Damage in Adolescents and Young Adults With Cancer

Recruiting now · Phase 3

Conditions studied: Hematopoietic and Lymphatic System Neoplasm, Malignant Solid Neoplasm

In brief

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

Who can join

Age: any, up to 39. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• < 40 years of age at the time of enrollment
• Patient must be a post-menarchal female and report that their initial menstrual period occurred > 6 months prior to enrollment. (Current menstrual status is not part of the inclusion criteria.)
• Newly diagnosed with first cancer, exclusive of breast cancer.
• Note: Apart from breast carcinoma, other tumor types originating in the breast are permitted (e.g., sarcoma, lymphoma).
• Planned treatment must include one or more of the following alkylating agents delivered with curative intent: cyclophosphamide, ifosfamide, procarbazine, chlorambucil, carmustine (BCNU), lomustine (CCNU), melphalan, thiotepa, busulfan, nitrogen mustard, or dacarbazine (DTIC).
• Expected cumulative cyclophosphamide equivalent dose (CED):
• For patients < 20 years of age at enrollment, the expected alkylator dose must be ≥ 4 g/m\^2 cumulative CED calculated according to the equation and specified drugs listed. Dacarbazine is not an eligible drug in this age group.
• For patients ≥ 20 years of age and < 35 years old at enrollment, any planned alkylator dose is permitted. Eligible patients must receive at least one of the alkylators listed below that contribute to CED. Dacarbazine is not an eligible drug in this age group.
• For patients ≥ 35 years of age at enrollment, any planned alkylator dose is permitted. Eligible patients must receive at least one of the alkylators listed that contribute to CED and/or dacarbazine, which IS an eligible drug in this age group.
• Note that CED includes all administration routes: intravenous (IV), oral (PO), IM.
• The planned total duration of therapy with eligible alkylators is expected to be completed within one year after enrollment. Note: treatment plans with prolonged maintenance periods extending beyond one year are permitted so long as those maintenance treatments are not expected to contain eligible alkylators.
• All patients and/or their parents or legal guardians must sign a written informed consent.
• All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met.

You may not qualify if…

• Any planned radiation to the pelvis; or cranial radiation ≥ 30 gray (Gy) to the hypothalamus, inclusive of any total body irradiation (TBI).
• Planned bilateral oophorectomy. Note: A participant's desire to pursue alternative fertility preservation procedures (i.e., embryo, oocyte, or ovarian tissue cryopreservation) will be allowed (and in fact encouraged).
• Congenital syndromes associated with infertility and decreased ovarian reserve at baseline. For example: Turner's Syndrome, Fragile X premutation carriers, Down syndrome, etc.
• Pre-existing seizure disorder, congenital long QT syndrome, pseudotumor cerebri; history of pulmonary embolism, venous thrombosis, or myocardial infarction. Note: Contact study chairs if questions arise about other pre-existing conditions.
• Receipt of long acting (depot) GnRH agonists within 6 months before enrollment. In contrast, subcutaneous GnRH agonist used for oocyte retrieval is not an exclusion; oral and other hormonal contraceptive use is also not an exclusion. Note: Please see protocol for the concomitant therapy restrictions for patients during the study treatment period. See protocol for information about oral and other hormonal contractive use during the study treatment period.
• Receipt of systemic chemotherapy (except for steroids and intrathecal chemotherapy) more than 7 days prior to study enrollment.
• Any prior radiation to the pelvis; or cranial radiation ≥ 30 Gy to the hypothalamus, inclusive of any total body irradiation (TBI).
• Patients who are pregnant are not eligible. A pregnancy test is required for female patients of childbearing potential.
• Lactating females who plan to breastfeed their infants for the duration of triptorelin therapy (24 weeks per dose).
• Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of triptorelin therapy (24 weeks per dose).
