About this study
Official title: A Phase I/II Study of ABT-888, An Oral Poly(ADP-ribose) Polymerase Inhibitor, and Concurrent Radiation Therapy, Followed by ABT-888 and Temozolomide, in Children With Newly Diagnosed Diffuse Pontine Gliomas (DIPG)
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.

PRIMARY OBJECTIVES:
- 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:
- To estimate the progression-free survival (PFS) distribution and to summarize the best tumor responses observed prior to progression or recurrence.
II. 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.
IV. 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.
- To explore quantifying PARP activity and deoxyribonucleic acid (DNA)-repair protein levels in biopsied atypical pontine gliomas, if available.
VI. To explore associations of molecular parameters from secondary aims III, IV, and V with PFS and overall survival (OS) after conclusion of clinical trial.
VII. 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.
VIII. 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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)
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.
Measured: 10 weeks
Percentage of Participants Observed to Have Unacceptable Toxicity During the Intra-patient Dose Escalation of Temozolomide During Maintenance Therapy (Feasibility Analysis Population)
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.
Measured: 28 days per treatment cycle
Overall Survival
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.
Measured: 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
Number of Phase I Patients Who Experienced Dose Limiting Toxicities (DLTs)
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.
Measured: 10 weeks
Secondary outcomes (8)
Progression-free Survival (PFS)
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.
Measured: 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
Percentage of Patients With Pseudo Progression
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.
Measured: Up to 6 months
Maximum Concentration of Veliparib (Cmax) on Days 1 and 4 (Measured in ng/mL) [Pharmacokinetic Parameter]
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.
Measured: Up to day 4

Primary outcome
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)
Time frame: 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.
Percentage of Participants Observed to Have Unacceptable Toxicity During the Intra-patient Dose Escalation of Temozolomide During Maintenance Therapy (Feasibility Analysis Population)
Time frame: 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.
Overall Survival
Time frame: 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.
Number of Phase I Patients Who Experienced Dose Limiting Toxicities (DLTs)
Time frame: 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.
