NCT03968406

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Maximum tolerated dose (MTD)

    MTD is determined by dose limiting toxicity (DLT). The MTD will be determine using the time-to-event Bayesian optimal interval (TITE-BOIN) model, and it is defined as the dose for which the isotonic estimate of the DLT rate is closest to the target DLT rate.

    Up to 30 days

Secondary Outcomes (6)

  • Incidence of adverse events

    Up to 2 years

  • Response rate

    From the start of study treatment until documentation of local or regional recurrence, progression, time to next therapy, and death, assessed up to 2 years

  • Local control rate

    From the start of study treatment until documentation of local or regional recurrence, progression, time to next therapy, and death, assessed up to 2 years

  • Time to progression

    From the start of study treatment until documentation of local or regional recurrence, progression, time to next therapy, and death, assessed up to 2 years

  • Progression-free survival

    From the start of study treatment until documentation of local or regional recurrence, progression, time to next therapy, and death, assessed up to 2 years

  • +1 more secondary outcomes

Other Outcomes (5)

  • Level of PAR inhibition

    Up to 2 years

  • Gamma-H2AX and RAD51 foci formation levels

    Up to 2 years

  • Functional Assessment of Cancer Therapy (FACT)

    Up to 2 years

  • +2 more other outcomes

Study Arms (1)

Treatment (talazoparib, radiation therapy)

EXPERIMENTAL

Patients receive talazoparib PO 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.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Provision of informed consent prior to any study specific procedures
  • Histologically-confirmed recurrent ovarian, fallopian tube, primary peritoneal cancer, endometrial, vaginal, or cervical cancer in the abdomen and pelvis
  • Subjects with stage IV disease are eligible as long as disease elsewhere (other than the site(s) to receive radiation therapy \[RT\]) is undetectable or stable (\>= 3 months) and immediate chemotherapy is not required. Willingness to discontinue any cytotoxic chemotherapeutic agents, immunotherapy, biologic therapy, and targeted therapies at least three weeks prior to start of investigational therapy
  • Hemoglobin \>= 10.0 g/dL and no blood transfusions in the 28 days prior to entry/randomization (choose whichever is most applicable to the study) (within 28 days prior to administration of study treatment)
  • Absolute neutrophil count (ANC) \>= 1.5 x 10\^9/L (within 28 days prior to administration of study treatment)
  • No features suggestive of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) on peripheral blood smear (within 28 days prior to administration of study treatment)
