Description of intervention(s) / exposure
Treatment: Drugs - Depatuxizumab mafodotin
Treatment: Drugs - Temozolomide
Treatment: Drugs - Lomustine

Experimental: ABT-414/temozolomide - Depatuxizumab mafodotin (ABT-414) administered once every 2 weeks in combination with temozolomide (TMZ) to adult participants

Experimental: ABT-414_adult - Depatuxizumab mafodotin (ABT-414) administered once every 2 weeks to adult participants

Active Comparator: Control_lomustine - Adult participants relapsing during temozolomide (TMZ) treatment or within the first 16 weeks after the first day of the last TMZ cycle received lomustine on Day 1 of every 42-day treatment period until one of the treatment withdrawal criteria was met, up to a maximum of 1 year.

Active Comparator: Control_ temozolomide - Adult participants relapsing 16 weeks or more after the first day of the last temozolomide (TMZ) cycle received TMZ on Day 1 to Day 5 for the first 28-day cycle, with dose escalation in subsequent cycles in case of adequate tolerance and treatment continuing until one of the treatment withdrawal criteria was met.

Experimental: ABT-414_ pediatric - Depatuxizumab mafodotin (ABT-414) administered once every 2 weeks to pediatric participants. Temozolomide (TMZ) was only allowed for pediatric participants if its use was in accordance with local clinical practice, and was not considered an investigational product for the study (unless this was a local requirement).


Treatment: Drugs: Depatuxizumab mafodotin
Adults: intravenous administration (1.25 mg/kg or 1.0 mg/kg body weight) over 30 to 40 minutes once every 2 weeks until one of the treatment withdrawal criteria was met. The dose was 1.25 mg/kg in the original protocol (Version 1) and Version 2, Amendment 1, and was lowered to 1.0 mg/kg in protocol Version 3, Amendment 2. Pediatric participants: Intravenous administration (1.0 mg/kg body weight for those who were 6 to 17 years old at the date of first dose, or 1.3 mg/kg for those who were 0 to 5 years old) over 30 to 40 minutes or as directed by the guidelines once every 2 weeks until one of the treatment withdrawal criteria was met, for a maximum of one year. If used in combination with temozolomide, depatuxizumab mafodotin was dosed on Day 1 and Day 15 of the TMZ cycle (assuming a standard regimen of 200 mg/m^2/day for 5 days of each 28-day cycle; for other TMZ schedules, timing of the depatuxizumab mafodotin dosing schedule were to be discussed with the medical monitor).

Treatment: Drugs: Temozolomide
Capsules administered orally, 150 mg/m^2 on Days 1-5 for the first 28-day cycle, with dose escalation to 200 mg/m^2 in subsequent cycles in case of adequate tolerance until one of the treatment withdrawal criteria was met.

Treatment: Drugs: Lomustine
Capsules administered orally, 110 mg/m^2 on Day 1 of every 42-day treatment period. Treatment continued until one of the treatment withdrawal criteria was met, for a maximum of one year.

Eligibility
Key inclusion criteria
Adult participants (greater than or equal to 18 years old):

- Histologically confirmed de novo (primary) glioblastoma with unequivocal tumor
progression or recurrence.

- In case of testing at the time of first progression: either at least 3 months after
the end of radiotherapy or have tumor progression that is clearly outside the
radiation field or have tumor progression unequivocally proven by surgery/biopsy

- Absence of any psychological, familial, sociological or geographical factors
potentially hampering compliance with the study protocol and follow-up schedule; such
conditions should be assessed with the patient before registration in the trial.

- Availability of adequate biological material (formalin-fixed paraffin embedded [FFPE]
tumor) for central testing of Epithelial Growth Factor Receptor (EGFR) amplification

- Presence of EGFR amplification confirmed by central assessment; participants with
undetermined EGFR status are excluded

- World Health Organization (WHO) Performance status 0 - 2

- No more than one line of chemotherapy (concurrent and adjuvant Temozolomide based
chemotherapy including in combination with another investigational agent is considered
one line of chemotherapy). Chemotherapy must have been completed at least 4 weeks
prior to randomization.

- Post surgery MRI within 48 hours following surgery, however an MRI scan has to be done
within 2 weeks prior to randomization.

- Surgery completed at least 2 weeks before randomization and patients should have fully
recovered as assessed by investigators.

- Renal function: calculated creatinine clearance = 30 mL/min by the Cockcroft-Gault
formula.

- Liver function: bilirubin < 1.5× upper limit of the normal range (ULN), alkaline
phosphatase and transaminases (ASAT) < 2.5× ULN

Pediatric sub-study participants (less than 18 years old):

- Histologically proven high grade glioma (HGG: WHO grade III glioma [e.g anaplastic
astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma], grade IV
glioma [e.g. glioblastoma, gliosarcoma] or diffuse intrinsic pontine glioma [DIPG]).

- Must either have recurrent/progressive tumor or, if newly diagnosed, have completed
any planned radiation therapy at least 4 weeks prior to first dose of ABT-414.

- The tumor tissue must have been determined to have EGFR amplification, (by local or
other testing service).

- Availability of adequate biological material for retrospective confirmatory central
testing of EGFR amplification

- Participant has sufficiently recovered from previous therapy. The investigator
believes that benefit of treating the pediatric subject with ABT-414 outweighs the
expected risks and that this treatment is in the best interests of the pediatric
subject.

- Renal function: calculated creatinine clearance = 30 mL/min by the Cockcroft-Gault
formula for pediatric patients =12 years of age and estimated glomerular filtration
rate = 30 mL/min/1.73 m^2 by modified Schwartz equation for pediatric patients < 12
years of age.

- Liver function: Total bilirubin = 1.5× upper limit of the normal range (ULN),
Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) <= 3× ULN.
Participants with Gilbert's syndrome documented in medical history may be enrolled if
total bilirubin is < 3 times ULN. Not allowed are participants with known chronic
liver disease and/or cirrhosis.

Summary
Brief summary
This study was conducted to evaluate the efficacy and safety of depatuxizumab mafodotin
(ABT-414) alone or with temozolomide versus temozolomide or lomustine alone in adult
participants with recurrent glioblastoma. The study also included a substudy to evaluate
safety, tolerability and pharmacokinetics of ABT-414 in a pediatric population.
