Intervention/exposure

Interventional
Description of intervention(s) / exposure
Eligible participants will be randomised to the study in 2:1 ratio to either Experimental group or Standard group.

The experimental group will receive veliparib capsules 200mg per oral two times per day for 6 weeks with concurrent radiotherapy (60Gy/30 fractions) followed 4 weeks later by a 6 month course of adjuvant temozolomide capsules (150-200mg/m2* per oral days 1-5, every 28 days) given concurrently with veliparib capsules (40mg per oral two times per day).

The standard treatment group will receive radiotherapy (60Gy/30 fractions) for 6 weeks plus concurrent temozolomide capsules daily per oral (75mg/m2) followed 4 weeks later by a 6 month course of adjuvant temozolomide capsules per oral (150-200mg/m2*) days 1-5 every 28 days

* During the adjuvant treatment phase all patients will start to receive temozolomide capsules at dose level 150mg/m2 per oral once daily days 1-5 in the first cycle of therapy. If this dose level is well tolerated, then the dose of temozolomide should be increased in subsequent cycles to 200 mg/m2. If the dose is not escalated in cycle 2, then the dose of temozolomide should remain at 150 mg/m2 for all 6 cycles.

To ensure appropriate control on the distribution of experimental treatment the Pharmacy Department at participating institutions will maintain a record of veliparib study drug received from the sponsor, the amounts dispensed for each patient, the amounts of study drug returned and the amounts destructed. Patients assigned to the veliparib study drug arm will be asked to return unused and empty study drug containers at each return visit to assess compliance to the treatment. Temozolomide is part of standard of care and drug dispensing and compliance will be monitored according to local hospital practices.

The radiotherapy treatment is standard of care and consists of a conventionally fractionated regimen, delivering a total dose of 60Gy, in a once daily schedule of 2 Gy per fraction for a total of 30 fractions, completed optimally in 6 weeks but up to a maximum of 7 weeks.

Eligibility
Key inclusion criteria
1) Adults, aged 18 years or older, newly diagnosed histologically confirmed GBM (WHO grade IV glioma) following surgery, with unmethylated MGMT promoter gene whom are considered suitable for radiotherapy (RT) plus concurrent temozolomide (TMZ), followed by adjuvant temozolomide (TMZ)
NOTE - Patients who undergo biopsy only are eligible only if standard RT and TMZ treatment is considered appropriate;
2) Available tissue for MGMT and biomarker analysis;
3) ECOG 0-2 if 70 years or younger, or ECOG 0 if older than 70 years;
4) Life expectancy of more than 12 weeks;
5) Adequate bone marrow function (platelets greater than 100 x 109/L, ANC greater than 1.5 x 109/L);
6) Adequate liver function (ALT/AST less than 1.5 x ULN);
7) Adequate renal function (creatinine clearance greater than 50 ml/min measured using Cockroft-Gault see appendix 16.4);
8) Willing and able to comply with all study requirements, including treatment, timing and/or nature of required assessments;
9) Signed, written informed consent.
Minimum age

Key exclusion criteria
1) Specific comorbidities or conditions (e.g. psychiatric) or concomitant medications which may impact with the administration of study related treatments or procedures;
2) Other co-morbidities or conditions that may compromise assessment of key outcomes;
3) No prior chemotherapy or recent cranial radiation within the last 2 years. No other prior or concomitant therapies for GBM allowed, excepting surgery
NOTE - Patients who had previous grade I-III glioma and have progressed to GBM are eligible assuming that they have not received prior cranial radiotherapy or TMZ for the treatment of glioma;
4) History of another malignancy within 2 years prior to registration. Patients with a past history of adequately treated carcinoma-in-situ, basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or superficial transitional cell carcinoma of the bladder are eligible. Patients with a history of other malignancies are eligible if they have been continuously disease free for at least 2 years after definitive primary treatment.

NOTE - Patients with localised cancer free of metastatic disease and of very low risk of recurrence are eligible. Eligibility of patients with localised cancer must be confirmed by the Study Chair.
5) Significant infection, including chronic active hepatitis B, hepatitis C, or HIV. Testing for these is not mandatory unless clinically indicated;
6) Concurrent illness, including severe infection that may jeopardise the ability of the patient to undergo the procedures outlined in this protocol with reasonable safety;
7) Serious medical or psychiatric conditions that might limit the ability of the patient to comply with the protocol;
8) Pregnancy, lactation, or inadequate contraception. Women must be post-menopausal, infertile, or use a reliable means of contraception. Women of childbearing potential must have a negative pregnancy test done within 7 days prior to registration.

Safety/efficacy
Statistical methods / analysis
One hundred and twenty patients will be randomised in a 2:1 ratio to the experimental and standard treatment arms, respectively. The randomisation will protect against selection bias and allow response to be estimated in a contemporary control group but no formal comparison between the randomised arms is planned.

Eighty patients on the experimental arm will have 80% power at alpha equal to 0.1 to detect an increase in response rate (proportion alive and progression-free at 6 months) from 53% to 65% using Fleming’s one-stage design.

A safety and feasibility analysis will be conducted when 60 patients have completed radiotherapy. The intervention is declared feasible if overall accrual achieved within 18 months, adequate treatment adherence (e.g. at least 70% of patients on experimental arm completed at least 70% of the treatment) and less than or equal to 30% of patients on the experimental therapy experience a grade 3 or 4 adverse event. If this is achieved, further patients will be enrolled to a total of 120 (80 on experimental and 40 on control arm). If these safety and feasibility conditions are not met then consideration will be given to stopping or modifying the study. If the study did stop at that point it would provide initial estimates of efficacy (approximately 40 patients on the active intervention would have 80% power at alpha equal to 0.1 to detect a large increase in response rate from 53% to 70%). Correlation with the DNA repair protein signature will be explored
