NCT05983965 | RECRUITING | T-cell Lymphoma

Study of Tazemetostat in Lymphoid Malignancies
Sponsor:

University of Alabama at Birmingham

Information provided by (Responsible Party):

Lauren Shea

Brief Summary:

Tazemetostat is an oral EZH2 inhibitor which has been FDA approved for adult patients with relapsed or refractory (R/R) follicular lymphoma (FL) whose tumors are positive for an EZH2 mutation as detected by an FDA-approved test and who have received at least 2 prior systemic therapies, and for adult patients with R/R FL who have no satisfactory alternative treatment option. We propose a study to evaluate the safety of tazemetostat in relapsed / refractory peripheral T-cell lymphoma.

      • 12. A negative urine or serum pregnancy test is required for all women of childbearing potential within 1 week prior to enrolling on this trial and within 3 days of first dose of study drug. Note: Urine pregnancy tests that cannot be confirmed as negative require a confirmatory negative serum pregnancy test.
      • Non-childbearing potential is defined as:
      • * Postmenopausal: Defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level in the postmenopausal range may be used to confirm post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, FSH measurements indicating post-menopausal status must be documented in patient's medical history.
      • * Permanently sterile: Documented permanent sterilization e.g., hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
      • 13. If female of childbearing potential, subject must not be pregnant or be breastfeeding and is required to have a negative urine or serum pregnancy test within 3 days prior to the first dose of study drug. In addition, females of childbearing potential must either practice complete abstinence or agree to use two effective methods of contraception simultaneously, beginning ≥ 28 days prior to start of tazemetostat, during tazemetostat treatment, and for at least 6 months after final dose of tazemetostat. See Appendix E regarding contraception guidelines.
      • 14. Male subjects must either practice complete abstinence or agree to use a latex or synthetic condom during any sexual contact with a female of childbearing potential, from first dose of tazemetostat, during study treatment including dose interruptions, and for 3 months after last dose of tazemetostat. This applies even to males who have undergone successful vasectomy with medically confirmed azoospermia.
