About
This phase I trial studies the side effects and best dose of talazoparib in combination with radiation therapy and to see how well they work in treating patients with gynecologic cancers that have come back after previous treatment (recurrent). Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving talazoparib in combination with radiation therapy may work better in treating patients with gynecologic cancers.
Full description
PRIMARY OBJECTIVE:
I. To determine the safety, tolerability, and maximally tolerated dose (MTD) of talazoparib combining talazoparib and fractionated radiotherapy in patients with refractory or recurrent ovarian, fallopian tube, primary peritoneal, cervical, or vaginal or endometrial carcinoma.
SECONDARY OBJECTIVES:
I. To determine the safety profile of talazoparib in combination with fractionated radiotherapy for recurrent gynecologic cancers.
II. To determine a preliminary anti-cancer activity of this combination at the MTD.
EXPLORATORY OBJECTIVES:
I. To explore the potential feasibility of using biomarkers in tumor tissue, whole blood or serum as predictive markers of treatment response.
II. To explore the impact of talazoparib when combined with radiotherapy for recurrent gynecologic cancers on 1) patient reported acute gastrointestinal (GI) toxicity and 2) overall longitudinal quality of life at week 5 of therapy.
OUTLINE: This is a dose escalation study of talazoparib.
Patients receive talazoparib orally (PO) once daily (QD) beginning on days -10 to -7 and continuing for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo radiation therapy 5 days a week (Monday-Friday) for up to 7 weeks.
After completion of study treatment, patients are followed up at 1, 3, 6, 9, and 12 months, and then every 6 months for up to 1 year.

White blood cells (WBC) > 3 x 10^9/L (within 28 days prior to administration of study treatment)
-
Platelet count >= 100 x 10^9/L (within 28 days prior to administration of study treatment)
-
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (within 28 days prior to administration of study treatment)
-
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal unless liver metastases are present in which case it must be =< 5 x ULN (within 28 days prior to administration of study treatment)
-
Serum creatinine =< 1.5 x institutional upper limit of normal (ULN) (within 28 days prior to administration of study treatment)
-
Eastern Cooperative Oncology Group (ECOG) performance status 0-1
- Note: If cannot fulfill ECOG 0-1, must fulfill inclusion criteria below (minimum life expectancy of >= 16 weeks)
-
Patients must have a life expectancy >= 16 weeks
-
Evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of study treatment, confirmed prior to treatment on day 1. Postmenopausal is defined as:
- Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments, luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50, radiation-induced oophorectomy with last menses > 1 year ago, chemotherapy-induced menopause with > 1 year interval since last menses, or surgical sterilization (bilateral oophorectomy or hysterectomy)
-
Patient of child-bearing potential is willing to adhere to using two forms of highly effective birth control. Condoms with spermicide and one of the following are acceptable: oral contraceptive or hormonal therapy or placement of an intrauterine device (IUD). Acceptable non-hormonal birth control methods include: total sexual abstinence, vasectomized sexual partner plus male condom, tubal occlusion plus male condom with spermicide, IUD plus male condom+spermicide. Acceptable hormonal methods include: etonogestrel implants (i.e. Implanon, Norplan), normal and low dose combined oral pills, norelgestromin/ethinyl estradiol (EE) transdermal system, intravaginal device (i.e. EE and etonogestrel) or cerazette (desogestrel). All of these would need to be combined with male condom with spermicide
-
Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up
-

-
For inclusion in biomarker endpoint, patients must fulfill the following criterion:
- Provision of informed consent for tumor biopsies * If a patient declines to participate in tumor biopsies, there will be no penalty or loss of benefit to the patient. The patient will not be excluded from other aspects of the study described in this Clinical Study Protocol, so long as they consent to that part
