What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Time periods mentioned: 14 days
  • Procedures mentioned: Biopsies

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "To be eligible for the therapy, patients are required to consent to a bone marrow biopsy at the beginning of study treatment."
  • "Cohort 1 will enroll patients at the starting dose of 0.25mg talazoparib for 14 days (dose level 1) and DLT (dose-limiting toxicity) rate will inform the subsequent dose levels (DLs)."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

This is a prospective phase I dose-escalation study, with the primary objective to access the MTD and find the RP2D of talazoparib, given in combination with standard of care dosing of pacritinib.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Official eligibility criteria

Inclusion Criteria: * Patients must have histologically or cytologically confirmed primary myelofibrosis (PMF), post-polycythemia vera-myelofibrosis (PPV-MF), post-essential thrombocythemia-myelofibrosis (PET-MF), chronic myelomonocytic leukemia, polycythemia vera, or essential thrombocytosis according to the 2008 World Health Organization criteria * Subject has at least 2 symptoms with a score ≥ 3 or a total score of ≥ 12, as measured by the MFSAF(Myelofibrosis Symptom Assessment Form) v4.0 * Subject classified as intermediate-2 or high-risk MF, as defined by the Dynamic International Prognostic Scoring System Plus (DIPSS+70). * Age \> 18 years. * ECOG (Eastern Cooperative Oncology Group) performance status 0-2 * Subject must have received prior treatment with a single JAK2 inhibitor 4.1.6 for at least 12 weeks with documented disease progression OR subject must have appearance of new splenomegaly that is palpable to at least 5 cm below the left costal margin (LCM) in subjects with no evidence of splenomegaly prior to the initiation of any first line JAK2 inhibitor * Baseline QTc (corrected QT interval) \<0.47 seconds (Bazett formula) * Patients must have normal organ function as defined in protocol. * Ability to understand and willingness to sign a written informed consent and HIPAA consent document Exclusion Criteria: * Patients may not be receiving any other investigational agents * Subjects must not be experiencing toxicity due to prior therapy that has not resolved to ≤Grade 1 by study registration, with the exception of sensory neuropathy related to previous systemic therapy exposure, alopecia and fatigue. * Patients that have transformed to Acute Myeloid Leukemia defined by \>20% blasts count on peripheral blood smear or bone marrow biopsy evaluation * Uncontrolled inter-current illness including, but not limited to, any other malignancy (with the exception of hormonal therapy for breast cancer/prostate cancer in remission \>1 year and for non-hormonal therapies for other cancers in remission for \>3 years), other ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. * Patients with history of hemorrhagic stroke and evidence of uncontrolled bleeding as well as bleeding disorder * Known HIV positive patients on combination antiretroviral therapy are ineligible because these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. * Pregnant or breast-feeding.
