Talazoparib
Last Updated: 04/28/2026
Phase 2 Trial of the Combination of the BET Inhibitor, ZEN003694 (ZEN-3694), and the PARP Inhibitor Talazoparib, in Patients With Molecularly-Selected Solid Tumors (ComBET)
Summary: This phase II trial tests whether ZEN003694 (ZEN-3694) in combination with talazoparib works to shrink tumors in patients with solid tumors that are unlikely to be cured or controlled with treatment and that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Another aim of this study is to find out if, and how, patients' genes influe...
A Randomized Phase I/II Study of Talazoparib or Temozolomide in Combination With Onivyde in Children With Recurrent Solid Malignancies and Ewing Sarcoma
Summary: The phase I portion of this study is designed for children or adolescents and young adults (AYA) with a diagnosis of a solid tumor that has recurred (come back after treatment) or is refractory (never completely went away). The trial will test 2 combinations of therapy and participants will be randomly assigned to either Arm A or Arm B. The purpose of the phase I study is to determine the highest ...
A Pharmacodynamics-Driven Trial of Talazoparib, an Oral PARP Inhibitor, in Patients With Advanced Solid Tumors and Aberrations in Genes Involved in DNA Damage Response
Summary: This phase II trial studies if talazoparib works in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repai...
Targeted Agent and Profiling Utilization Registry (TAPUR) Study
Summary: The purpose of the study is to learn from the real world practice of prescribing targeted therapies to patients with advanced cancer whose tumor harbors a genomic variant known to be a drug target or to predict sensitivity to a drug. NOTE: Due to character limits, the arms section does NOT include all TAPUR Study relevant biomarkers. For additional information, contact TAPUR@asco.org, or if a pati...
A Phase IB/II Multi-Cohort Study of Targeted Agents and/or Immunotherapy With Atezolizumab for Patients With Recurrent or Persistent Endometrial Cancer
Summary: This is a Phase IB/II multi-cohort study designed to evaluate the efficacy and safety of targeted agents with or without cancer immune checkpoint therapy with atezolizumab in participant with recurrent and/or persistent endometrial cancer. The main protocol provides a platform for genomic screening with homogeneous basic eligibility criteria in order to direct study participants into biomarker-mat...
I-SPY Trial (Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging And moLecular Analysis 2)
Summary: The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.
Modular Phase 1B Hypothesis-Testing, Biomarker-Driven, Talazoparib Combination Trial (TalaCom)
Summary: This phase Ib trial is to find out the best dose, possible benefits and/or side effects of talazoparib when given in combination with palbociclib, axitinib, or crizotinib in treating patients with solid tumors that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). PARPs are proteins that help repair damaged DNA, the genetic material that serves...
Phase I Study of Talazoparib in Combination With Radiation Therapy for Locally Recurrent Gynecologic Cancers
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 tu...
A Phase I Study of Talazoparib and Consolidative Thoracic Radiotherapy for Extensive Stage Small Cell Lung Cancer
Summary: This is a phase I, dose escalating study evaluating the safety of combining talazoparib and low dose consolidative thoracic radiotherapy for small cell lung cancer patients. This study will also determine the maximum tolerated dose (MTD) of talazoparib in combination with low dose thoracic radiotherapy. Patients will start on talazoparib on day 1 of study intervention, and will continue to orally ...
A Phase I Study of Trifluridine/ Tipiracil Plus the Poly (ADP) Ribose Polymerase Inhibitor Talazoparib in Advanced Cancers
Summary: This phase I trial investigates the side effects and best dose of talazoparib when given together with trifluridine/tipiracil for the treatment of patients with colorectal or gastroesophageal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Drugs used in the chemotherapy, such as trifluridine/tipiracil, work in different ways to st...
Prospective and Multicentric Study Evaluating DNA Double-strand Breaks (DSBs) REpair Factors (POLQ, Shieldin Complex and 53BP1) Expression as Biomarker of PARP Inhibitor Resistance in Patients With Deleterious Germline Mutation in BRCA 1/2 and HER2-negative, Metastatic or Locally Advanced Breast Cancer.
Summary: The purpose of this study is to assess whether expression of not only POLQ/Polθ, but also Shieldin complex and/or 53BP1 are correlated with primary and/or acquired resistance to PARPi (Poly(ADP-Ribose) Polymerases inhibitors) in a sub-population of locally advanced or metastatic breast cancer patients and vary regarding type and location of gBRCA1/2 mutations. This translational research program i...
Phase II Study of Talazoparib With Androgen Deprivation Therapy and Abiraterone in Castration Sensitive Prostate Cancer
Summary: This phase II trial studies the effect of talazoparib with androgen deprivation therapy and abiraterone in treating castration sensitive prostate cancer patients. Talazoparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a ty...
