Study Description

Brief Summary

This phase I/II trial studies the side effects and the best dose of veliparib when given together with radiation therapy and temozolomide and to see how well they work in treating younger patients newly diagnosed with diffuse pontine gliomas. Veliparib 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. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells either by killing the cells or by stopping them from dividing. Giving veliparib with radiation therapy and temozolomide may kill more tumor cells.

Detailed Description

PRIMARY OBJECTIVES:
  1. To identify the maximum-tolerated dose or recommended Phase II dose of ABT-888 (veliparib) which can be safely administered concurrently with radiation therapy, followed by maintenance therapy with ABT-888 and temozolomide (TMZ), in patients with newly diagnosed diffuse pontine gliomas (DIPG). (Phase I) II. To study the plasma pharmacokinetics (PK) of ABT-888 during ABT-888 and radiation therapy. (Phase I) III. To study the feasibility of intra-patient dose escalation of TMZ during maintenance therapy with ABT-888 and TMZ. (Phase I) IV. To describe the toxicities associated with administering ABT-888 and radiation therapy, followed by ABT-888 and TMZ, in patients with newly diagnosed DIPG. (Phase I) V. To estimate the proportion of newly diagnosed DIPG patients treated on protocol that are determined to have experienced pseudo progression. (Phase I) VI. To estimate the overall survival distribution for newly diagnosed patients with DIPG treated with the combination of ABT-888 and radiation therapy, followed by ABT-888 and TMZ, and compare to Pediatric Brain Tumor Consortium (PBTC) historical controls. (Phase II) VII. To study the feasibility of intra-patient dose escalation of TMZ during maintenance therapy with ABT-888 and TMZ. (Phase II) VIII. To estimate the proportion of newly diagnosed DIPG patients treated on protocol that are determined to have experienced pseudo progression. (Phase II)
SECONDARY OBJECTIVES:
  1. To estimate the progression-free survival (PFS) distribution and to summarize the best tumor responses observed prior to progression or recurrence.

  2. To explore the plasma PK of ABT-888 during ABT-888 and radiation therapy. III. To explore peripheral blood mononuclear cell (PBMC) poly (ADP-ribose) polymerase 1(PARP) activity before and after treatment with ABT-888.

  3. To explore quantifying non-homologous end-joining (NHEJ) activity or gamma-H2A histone family, member X (H2AX) levels (as surrogate markers of unrepaired double-strand breaks (DSBs)) in PBMC before and after treatment with ABT-888.

  4. To explore quantifying PARP activity and deoxyribonucleic acid (DNA)-repair protein levels in biopsied atypical pontine gliomas, if available.

  5. To explore associations of molecular parameters from secondary aims III, IV, and V with PFS and overall survival (OS) after conclusion of clinical trial.

  6. To explore the quantitative magnetic resonance (MR) measures of relative cerebral blood volume (rCBV), vascular permeability (Ktrans, fractional plasma volume [vp], and extravascular extracellular space volume fraction [ve] values), and apparent diffusion coefficient (ADC) within the first six months of initiating protocol treatment to correlate with disease outcome and determine whether such metrics differentiate patients with pseudo progression from those with true early progressive disease.

  7. To explore the potential utility of urine biomarkers as a novel, non-invasive method of detecting and tracking changes in the status of pediatric brain stem gliomas.

OUTLINE: This is a phase I, dose-escalation study of veliparib followed by a phase II study.

    Primary Outcome Measures

    1. Maximum-tolerated Dose of Veliparib Defined as Highest Dose Level With Fewer Than 2 Dose Limiting Toxicities in 6 Patients as Assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (Phase I) [10 weeks]

      The traditional 3+3 dose finding algorithm was used to estimate the maximum-tolerated dose of veliparib given concurrently with radiation therapy. The dose-limiting toxicity observation period was the first 10 weeks of therapy. Dose-limiting toxicities included any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with a few exceptions (see section 5.2.1.2 of the protocol document), any grade 2 non-hematologic toxicity that persisted for >7 days and considered medically significant that required treatment interruption; grade 3 or higher thrombocytopenia or grade 4 neutropenia; and any Veliparib related adverse event that led to a dose reduction or the permanent cessation of therapy.

    2. Percentage of Participants Observed to Have Unacceptable Toxicity During the Intra-patient Dose Escalation of Temozolomide During Maintenance Therapy (Feasibility Analysis Population) [28 days per treatment cycle]

      Unacceptable toxicities during maintenance included events at least possibly attributable to Veliparib and temozolomide (TMZ) such as any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with some exceptions (e.g., grade 3 nausea/vomiting <5 days, grade 3 fever or infection <5 days), grade 3+ thrombocytopenia, grade 4 neutropenia, delay >14 days in starting subsequent cycle due to neutrophil <1,000/mm3 or platelet <100,000/mm3. Maintenance therapy was initiated with 25 mg/m2 Veliparib and 135 mg/m2 of TMZ, with the possibility to escalate TMZ to 175 mg/m2 and 200 mg/m2 in courses 2 and 3, respectively, if no unacceptable toxicities occurred following one course of treatment at each of the dose levels to be tested. Intra-patient dose escalation to a given dose (135, 175, or 200 mg/m2) was halted based on rules employed in 3+3 designs. This dose escalation was intended for all patients but was halted early, during the phase I portion, as it was not well tolerated.

    3. Overall Survival [Time from initiation of therapy to the date of death from any cause or to the date patient was known to be alive for surviving patients, assessed to up to 3 years]

      Overall survival was defined as the interval from date on treatment to date of death from any cause or to date of last follow-up. Patients who had not failed (died) at the time of analyses were censored at their last date of contact. The method of Kaplan and Meier was used to estimate overall survival. The 3-year estimate with a 95% confidence interval is reported.

    4. Number of Phase I Patients Who Experienced Dose Limiting Toxicities (DLTs) [10 weeks]

      DLTs were defined as any of the following adverse events that were at least possibly attributable to Veliparib observed during the dose finding phase (the first 10 weeks of therapy). Hematologic dose limiting toxicities included grade 3 and higher thrombocytopenia or grade 4 neutropenia. Non-hematologic dose limiting toxicities included any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with some exceptions (e.g., nausea and vomiting of <5 days; fever or infection of <5 days; hypophosphatemia, hypokalemia, hypocalcemia or hypomagnesemia responsive to oral supplementation; elevation of transaminases that return to levels meeting eligibility criteria within 7 days), or any grade non-hematologic toxicity that persisted for >7 days and considered medically significant or sufficiently intolerable by patients that required treatment interruption.

    Secondary Outcome Measures

    1. Progression-free Survival (PFS) [Time from initiation of treatment to the earliest date of failure (disease progression, death from any cause, or second malignancy), assessed up to 3 years]

      PFS was defined as the interval from date of treatment initiation to date of first event (disease progression or relapse, second malignancy or death from any cause). Patients who had not failed at the time of analyses were censored at their last date of contact. The method of Kaplan and Meier was used to estimate PFS. A 3-year estimate with a 95% confidence interval is reported.

    2. Percentage of Patients With Pseudo Progression [Up to 6 months]

      For participants that showed possible tumor progression (pseudo progression) on magnetic resonance imaging (MRI) during the first 6 months of therapy, treating physicians had the option of allowing patients to remain on therapy and repeating the disease assessment in 4-6 weeks. If the repeat MRI at 4-6 weeks showed disease progression, the patient was noted to have true disease progression (and the progression date corresponded to that of the first MRI). If the repeat MRI at 4-6 weeks did not show disease progression, then the patient was noted to have pseudo progression. The percentage of patients observed to have experienced pseudo progression was provided with a 95% confidence interval.

    3. Maximum Concentration of Veliparib (Cmax) on Days 1 and 4 (Measured in ng/mL) [Pharmacokinetic Parameter] [Up to day 4]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis. Cmax measures the highest concentration of drug.

    4. Mean Apparent Clearance (CL/F) for Veliparib [Pharmacokinetic Parameter] [Up to day 4]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis.

    5. Maximum Concentration of Veliparib (Cmax) on Day 1 (Measured in μM) [Pharmacokinetic Parameter] [Day 1]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis. Cmax measures the highest concentration of drug.

    6. Apparent Volume of Distribution (Vd/F) for Veliparib [Pharmacokinetic Parameter] [Up to day 4]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis.

    7. Terminal Half-life (t1/2) for Veliparib [Pharmacokinetic Parameter] [Up to day 4]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis.

    8. Trough for Veliparib [Pharmacokinetic Parameter] [Up to day 4]

      During course 1, blood samples were collected pre-veliparib on day 1, at 0.5, 1, 2, and 6-8 hours after the first dose, pre-veliparib on day 4 (steady state), and 2 hours after the morning dose. Veliparib concentrations were measured using a liquid chromatography tandem mass spectrometry assay and pharmacokinetic parameters were evaluated using a non-compartmental analysis.

    Other Outcome Measures

    1. Percentage of Participants With Significant Changes in Poly(ADP-ribose) Polymerase (PARP) Levels Post-Veliparib, as Measured in Peripheral Blood Monocytes (PBMCs) [Baseline and up to 11 weeks]

      Blood samples were collected from patients and assessed pre- and post-Veliparib to assess treatment-induced changes. A significant change in PBMC PARP level was arbitrarily defined as a >50% increase or decrease from the pre-treatment level, documented at week 6 and/or week 11 after starting protocol therapy.

    2. Change in Non-homologous End-joining (NHEJ) Activity as Measured in Peripheral Blood Monocytes (PBMCs) [Baseline to up to 3 years]

      Levels of non-homologous end-joining (NHEJ) activity were to be calculated. Cox models to explore associations between the levels of NHEJ and outcome (progression-free survival and overall survival) were planned, in addition to looking at associations between Poly(ADP-ribose) polymerase (PARP) activity and NHEJ levels.

    3. Change in Level of Gamma-H2A Histone Family, Member X (H2AX) Measured in PBMCs [Baseline to up to 3 years]

      Levels of gamma-H2A histone family, member X (H2AX) were to be calculated. Cox models to explore associations between the levels of gamma-H2AX and outcome (progression-free survival and overall survival) were planned, in addition to looking at associations between Poly(ADP-ribose) polymerase (PARP) activity and gamma-H2AX levels.

    4. Levels of Urinary Biomarkers [Baseline to up to 3 years]

      Urine samples were analyzed for a panel of biomarkers. Netrin-1 levels were determined by ELISA. Levels of matrix metalloproteinase 3 (MMP3) and basic fibroblast growth factor (bFGF) were analyzed using custom Luminex® screening assays. Tissue inhibitor of metalloproteinase 1 (TIMP1) levels were analyzed using a Luminex® performance assay. Protein concentrations are given in picograms per microgram (pg/μg), and were determined by dividing the concentration of the target protein in the sample (pg/mL) by the concentration of total protein in the sample (μg/mL) as a normalization measure.

    Participant Flow

    Recruitment Details Patients up to 21 years of age with newly diagnosed diffuse intrinsic pontine gliomas (DIPGs) were enrolled at Pediatric Brain Tumor Consortium (PBTC) member institutions. The first patient was enrolled on 2/1/2012 and the last patient was enrolled on 01/20/2016.
    Pre-assignment Detail Of the 66 patients enrolled, 1 phase II patient was deemed ineligible due to an elevated alanine aminotransferase (ALT). Of note, the 6 phase I patients who were treated at the established maximum tolerated dose (MTD) during the phase I portion of the trial were also counted as phase II patients in analyses of phase II objectives.

    1. Primary Outcome
    Title Maximum-tolerated Dose of Veliparib Defined as Highest Dose Level With Fewer Than 2 Dose Limiting Toxicities in 6 Patients as Assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (Phase I)
    Description The traditional 3+3 dose finding algorithm was used to estimate the maximum-tolerated dose of veliparib given concurrently with radiation therapy. The dose-limiting toxicity observation period was the first 10 weeks of therapy. Dose-limiting toxicities included any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with a few exceptions (see section 5.2.1.2 of the protocol document), any grade 2 non-hematologic toxicity that persisted for >7 days and considered medically significant that required treatment interruption; grade 3 or higher thrombocytopenia or grade 4 neutropenia; and any Veliparib related adverse event that led to a dose reduction or the permanent cessation of therapy.
    Time Frame 10 weeks

    Analysis Population Description
    The first 18 patients enrolled on the study were phase I patients used to determine the maximum tolerated dose or the recommended phase II dose and to address other objectives of the phase I component of this trial.
    Arm/Group Title Phase I Patients
    Arm/Group Description The first 18 patients enrolled on the study were phase I patients used to determine the maximum tolerated dose or the recommended phase II dose and to address other objectives of the phase I component of this trial. The starting dose level was 50 mg/m2/dose twice a day (BID) and other dose levels to be studied were 65 and 85 mg/m2/dose BID. If the 85 mg/m2 dose level was tolerated, there was a plan to study a higher dose level (110 mg/m2/dose BID) but only if supported by clinical data.

    2. Primary Outcome
    Title Percentage of Participants Observed to Have Unacceptable Toxicity During the Intra-patient Dose Escalation of Temozolomide During Maintenance Therapy (Feasibility Analysis Population)
    Description Unacceptable toxicities during maintenance included events at least possibly attributable to Veliparib and temozolomide (TMZ) such as any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with some exceptions (e.g., grade 3 nausea/vomiting <5 days, grade 3 fever or infection <5 days), grade 3+ thrombocytopenia, grade 4 neutropenia, delay >14 days in starting subsequent cycle due to neutrophil <1,000/mm3 or platelet <100,000/mm3. Maintenance therapy was initiated with 25 mg/m2 Veliparib and 135 mg/m2 of TMZ, with the possibility to escalate TMZ to 175 mg/m2 and 200 mg/m2 in courses 2 and 3, respectively, if no unacceptable toxicities occurred following one course of treatment at each of the dose levels to be tested. Intra-patient dose escalation to a given dose (135, 175, or 200 mg/m2) was halted based on rules employed in 3+3 designs. This dose escalation was intended for all patients but was halted early, during the phase I portion, as it was not well tolerated.
    Time Frame 28 days per treatment cycle

    Outcome Measure Data

    Analysis Population Description
    Patients were combined across dose levels since they received the same maintenance therapy. Though this objective was intended for all patients, only the first 12 enrolled were included as the dose-escalation stopped early. 1 of the first 12 patients did not start maintenance due to early progression, so 11 patients started dose level 1.

    Statistical Analysis 1
    Statistical Analysis Overview Comparison Group Selection Phase I Patients, Dose Level 2 (175 mg/m2), Dose Level 3 (200 mg/m2)
    Comments Intra-patient dose escalation of temozolomide during maintenance was assessed based on similar rules employed in traditional 3+3 designs. For example intra-patient dose escalation would be halted if at any time 2 out of first 2-6 patients experienced dose-modifying toxicities at a given dose level or if 4 out of first 12 patients experienced dose-modifying toxicities at a given dose level.
    Type of Statistical Test Other
    Comments This was descriptive in nature. Two of the first 5 patients who were escalated to 175 mg/m2 of temozolomide during the maintenance intra-patient dose escalation had dose-modifying toxicities (DMTs). Since the ad hoc stopping rule was met, intra-patient dose escalation was halted and all subsequent patients were to receive 135 mg/m2 of temozolomide during maintenance.

    Title Overall Survival
    Description Overall survival was defined as the interval from date on treatment to date of death from any cause or to date of last follow-up. Patients who had not failed (died) at the time of analyses were censored at their last date of contact. The method of Kaplan and Meier was used to estimate overall survival. The 3-year estimate with a 95% confidence interval is reported.

    Outcome Measure Data

    Analysis Population Description
    53 patients were evaluable for outcome analyses (47 phase II patients + 6 phase I patients treated at the MTD). 50 patients were evaluable; 1 patient withdrew prior to beginning protocol therapy and 2 patients did not receive adequate study drug to be evaluable for efficacy. To be evaluable patients had to receive at least one dose of Veliparib.
    Arm/Group Title Phase II Patients + Phase I MTD Patients
    Arm/Group Description Phase II patients were those enrolled after the maximum tolerated dose was established in the phase I portion of this trial. Six patients enrolled as phase I patients but who were treated with the established maximum tolerated dose of 65 mg/m2/day twice a day (BID) were also considered phase II patients. There were 53 eligible phase II patients (including the latter six patients). Fifty (50) of these patients were evaluable for outcome analyses as 1 patient withdrew prior to beginning protocol therapy and 2 other patients did not receive adequate study drug to be evaluable for efficacy. To be evaluable for assessing overall survival, patients had to receive at least one dose of Veliparib.

    Adverse Events

    Time Frame Approximately 1 year after starting treatment
    Adverse Event Reporting Description Adverse events (AEs) were graded according to CTCAE v4.0. AEs collected per protocol included: a) grade 1 and 2 AEs if attribution was at least possibly related to veliparib and b) all grade 3+ AEs on treatment and within 30 days off treatment. All AEs collected are reported. As the intra-patient escalation of TMZ during maintenance was by course (rather than patient) and was halted early (only 5(3) patients escalated to 175(200) mg/m2), AEs were not reported separately by course-specific doses.
