Talazoparib and Avelumab for the Treatment of Metastatic Renal Cell Carcinoma

Trial Status: Active

This phase II trial studies how well talazoparib and avelumab work in treating patients with renal cell carcinoma (the most common kidney cancer) that has spread to other places in the body (metastatic). Avelumab is an antibody that recognizes and attaches to a molecule called PD-L1. PD-L1 is found on the surface of some tumor cells, where it functions like a shield to prevent the tumor cells from being attacked by the immune system. When avelumab attaches to PD-L1, it may break up the protective shield and may help the immune system recognize and kill tumor cells. Talazoparib inhibits (stops) the normal activity of certain molecules called PARPs. PARPs are proteins that help repair damage to DNA, the genetic material that serves as the body’s instruction book. Changes (mutations) in DNA can cause tumor cells to grow quickly and out of control. But PARP inhibitors like talazoparib have been shown to keep PARP from working, so tumor cells can’t repair themselves, and they stop growing. Giving avelumab and talazoparib together may be more effective than giving either drug alone in treating patients with renal cell cancer.

All women will be considered childbearing potential unless meeting criteria including: * Achieved post-menopausal status as defined by cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause and have follicular stimulation hormone showing postmenopausal state. Women who have been amenorrhoeic for >= 12 months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anorexia, low body weight, ovarian suppression, anti-estrogen therapy or other medically inducible reasons * Documented hysterectomy or bilateral oophorectomy surgery * Medically confirmed ovarian failure * Sexually active participants and their partners must agree to use medically accepted methods of contraception (i.e. barrier methods including condoms, female condom, or diaphragm with spermicidal gel) during the study and for 7 months after the last dose of the study treatment for females, and 4 months for males

  • LIFESTYLE REQUIREMENTS: The teratogenic risk of combination talazoparib and avelumab remains unknown. Talazoparib has been associated with teratogenic risk. Therefore, all fertile male patients and female patients who are of childbearing potential, and who remain sexually active during this study and who are at risk for pregnancy must agree for 2 methods of contraception (one which is considered highly effective), for at least 7 months after last dose of study treatment for women, and for at least 4 months after last dose of study treatment for men. Study team personnel including investigators and clinical nursing staff should confirm that the patient and their partner have selected 2 appropriate methods of contraception from the list of contraceptive methods (as listed below). The study team will confirm that the patient has received informed consent regarding proper use. Continued confirmation of contraceptive use will be obtained during the study protocol at time points outlined, with documentation of affirmation. Highly effective contraceptive methods include, but not limited to: * Established hormonal methods of contraception associated with ovulation inhibition (i.e. oral, inserted, injected or implanted), provided that the patient or male patient’s partner remains on same treatment throughout the entire study period * Intrauterine device * Male sterilization with absence of sperm in post vasectomy ejaculate * Bilateral tubal ligation, bilateral salpingectomy or bilateral tubal occlusive procedure * Female partner of male patient who meets criteria for non-childbearing potential as defined above, including: ** Medically confirmed ovarian failure ** Hysterectomy and/or bilateral oophorectomy ** Post-menopausal state as defined as a cessation of regular menses > 12 months with no alternative pathologic or physiologic cause, with serum follicular stimulating hormone within reference range for postmenopausal women by laboratory * All sexually active male patients must agree to prevent potential transfer or exposure of study agents through ejaculate by using a condom consistently and correctly. Condom use must begin at the first dose of investigational product, and for at least 30 days after avelumab or after at least 4 months after last dose of talazoparib, whichever is later

OUTLINE:

Patients receive talazoparib orally (PO) once daily (QD) on days 1-28 and avelumab intravenously (IV) over 1 hour on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 30 days for 3 months, and then every 12 weeks thereafter.
