E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- Evaluate the impact of a cyclophosphamide-free regimen on the ovarian function recovery defined as menstrual resumption within 12 months following the end of chemotherapy - Evaluate the impact of a cyclophosphamide-free regimen on the development of ovarian failure defined as serum FSH >40 IU/L at 12 months following the end of chemotherapy
|
|
E.2.2 | Secondary objectives of the trial |

E.4 | Principal exclusion criteria |
Patients meeting any ONE of the following criteria are not eligible for this study: 1. History of prior malignant disease (breast or non-breast) or non-malignant condition which was treated with chemotherapy, pelvic irradiation or any therapy that could potentially affect ovarian function. 2. Previous history of amenorrhea > 3 months within the last 2 years (excluding pregnancy). 3. Ovarian insufficiency defined as serum FSH > 20 IU/L at the local laboratory, anytime during the menstrual cycle. 4. Any ovarian pathology or abnormalities at the screening pelvic ultrasound, except for functional follicular cysts. 5. Pregnant or breastfeeding patients. 6. Inability or unwillingness to use effective contraception during and up to 3 months after the last dose of study medication. Effective methods include the following: non-hormonal intrauterine device, barrier method - condoms, diaphragm – also in conjugation with spermicidal jelly, or total abstinence. Oral, injectable, or implant hormonal contraceptives are not allowed. 7. Concurrent use of any other cytotoxic or hormonal agent, namely GnRH agonists. 8. Prior pre-existing peripheral neuropathy of any cause, including diabetes mellitus, alcohol abuse, HIV infection, autoimmune and hereditary neuropathies, amyloidosis, hypothyroidism, vitamin deficiencies. 9. Serious cardiac illness, uncontrolled hypertension or medical condition that would affect administration of chemotherapy and compliance to study procedures. 10. Known sensitivity to any of the study medications. |
