About

Bevacizumab (called also Avastin ®) is a medicine preventing the creation of new blood vessels (a process called "angiogenesis"). This can reduce blood flow of the tumor and then decreasing the contribution of nutriments and oxygen to the cancer cells and prevent the tumor from growing.

In various types of cancers, as lung, breast, colorectal and renal cancer, addition of the bevacizumab to chemotherapy allowed to improve the disease outcome. The bevacizumab already benefits from a marketing authorization (MMA) for these various types of cancers.

The bevacizumab has also obtained MMA for the treatment of the ovarian cancer in its most frequent histological form (ovarian carcinoma). Clinical trials conducted in this indication demonstrated the importance to pursue the treatment by bevacizumab after the chemotherapy is ended.

This anti-angiogenic medicine is thought to be of a potential interest in sex cords- stromal since this tumors are very well vascularized.

The ALIENOR study aims to explore the interest and the clinical benefit of associating bevacizumab to the paclitaxel in order to treat patients suffering from recurring sex cords- stromal tumor treated beforehand by platinum chemotherapy

  • Adequate coagulation panel:

    • PT ≤ 1.2 ULN
    • aPTT ≤ 1.5 ULN
    • INR ≤ 1.5 ULN

  • Ability to understand and sign informed consent and willingness to comply with the study procedures before study entry

  • Women of childbearing potential* are required to have a negative serum pregnancy test within 7 days prior to study treatment initiation (i.e. Cycle 1 Day 1) and are willing to use adequate contraceptive method during the whole study period and for up to 6 months after the last treatment intake

    *: Female patients who meet at least one of the following criteria are defined as women of non-childbearing potential:

    • ≥ 50 years old and naturally amenorrheic for ≥ 1 year

    • Permanent premature ovarian failure confirmed by a specialist gynaecologist

      • Previous bilateral salpingo-oophorectomy or hysterectomy
      • XY genotype, Turner's syndrome, or uterine agenesis
      • Female patient who do not meet at least of the above criteria are defined as women of childbearing potential

    • Current or recent treatment with another investigational drug within 30 days of first study treatment dosing or within 6 weeks in case of prior nitrozo-urea and or mitomycin C treatment. In case of hormonotherapy , patients will be eligible if hormonotherapy is discontinued within at least 1 week before treatment initiation
