E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Recurrent or Refractory Anaplastic Astrocytoma (WHO grade III) or secondary Glioblastoma (WHO grade IV) |
|
E.1.1.1 | Medical condition in easily understood language |
Anaplastic astrocytoma and glioblastoma are rare malignant brain tumours. They arise from the brain cells themselves (primary tumour), and are therefore not to be confused with brain metastases. |

1. The patient has provided written informed consent prior to any study-related procedure.
2. The patient is at least 18 years of age and equal to or below 70 years.
3. The patient has a present diagnosis of AA or secondary GBM.
4. The patient has a measurable lesion (> 1 cm3 in volume, central MRI review).

8. The patient has not received more than 2 chemotherapy regimens. Radiation with concomitant chemotherapy, followed by adjuvant chemotherapy, is considered as one chemotherapy regimen.
9. The patient is eligible for chemotherapy.
10. The patient is on a maximum dose of 4 mg/day dexamethasone or equivalent doses for other corticosteroids, which has been stable or decreasing for at least 3 weeks prior to Screening.
11. The patient is male or a non-pregnant, non-lactating female.
12. Females of childbearing potential must have a negative beta-HCG pregnancy test at Screening. Females of childbearing potential and males must practice strict birth control (see Section 8.2).
13. The patient must have recovered from acute toxicity caused by any previous therapy.
14. The patient has a life expectancy of at least 3 months.
15. The patient has a Karnofsky Performance Status of at least 70%.

|
E.4 | Principal exclusion criteria |
1. Patient unable or not willing to comply with the protocol regulations.
2. The investigator deems it necessary to surgically (re-)resect the present tumor (NOTE: the patient might still be eligible for randomization at a later timepoint, see inclusion criterion 7 and exclusion criterion 3).
3. Tumor surgery, tumor debulking, or other neurosurgery within 3 months prior to randomization. If a ≤ 48-hour routine post-surgery MRI (in accordance with study specifications) qualifies the patient for study participation (see inclusion criterion 7), the patient can be randomized 30 ± 7 days post-surgery.
4. Radiotherapy or stereotactic (gamma knife) radiosurgery within 3 months prior to randomization.

8. Screening MRI shows a mass effect caused by the tumor defined as significant compression of the ventricular system and/or a midline shift ( ≥ 3 mm, central MRI review). Compression of the ventricular
system and/or a midline shift ≥ 3 mm only due to the presence of (a) cyst(s) or scarring processes does not exclude an individual from the study.
9. Participation in another clinical study with another investigational medicinal product within 30 days prior to randomization.
10. History of a second independent malignant disorder within 5 years, except for carcinoma in situ of the cervix and basal cell carcinoma.
11. Presence of poorly controlled seizures, defined as:
a. Seizures, which require frequent hospitalizations or other medical interventions because of their serial nature and/or clinical symptoms.
b. Seizure symptoms, which significantly interfere with normal life and restrict medical treatments that are necessary for patient care.
12. Clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure, unstable angina, or poorly controlled arrhythmia. Myocardial infarction within 6 months prior to randomization.
13. HIV, HBV or HCV infection.

a. Lung function: vital capacity ≤ 70%
b. Status following sequential or concomitant thoracic irradiation
c. Increased risk for a pulmonary toxicity induced by BCNU (Carmustine) or CCNU (Lomustine). Risk factors include smoking, presence of a respiratory condition, pre-existing radiographic pulmonary abnormalities, exposure to agents that cause lung damage.

E.5 End points |
E.5.1 | Primary end point(s) |
• Survival rate at 24 months |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary objective of the study is to compare the overall survival (OS) at 24 months of patients treated with AP 12009 at a concentration of 10 μM over a 7-day period every other week versus standard chemotherapy treatment with TMZ or BCNU. Consequently, the primary efficacy endpoint is the proportion of patients showing survival 24 months after randomization for the ITT population.
(see Protocol, e.g. Synopsis) |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints with special relevance:
• Median overall survival (mOS)
• 14-month progression rate
Secondary efficacy endpoints:
• Overall response rate (best response according to Macdonald criteria, PR and CR)
• Tumor control rate (CR, PR, and SD)
• Duration of response
• Progression rate at 10, 12, 16, 18, 21, and 24 months
• Time to progression (months)
• Survival rate at 12, 18, 21, 27, and 30 months, and at 3 and 4 years
• Quality of Life (EORTC QLQ-C30, Independent Living Score [ILS]) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
In the final analysis the primary endpoint as well as the secondary endpoints with special relevance will be tested hierarchically. A closed test procedure with the following sort order will be used for the final analysis: 1) 24-month survival rate, 2) Median overall survival (Kaplan-Meier), 3) 14-month progression rate.
Special emphasis will be given to the interim analysis of progression rates at 14 months.
Similar statistical methods to those planned for the primary endpoint will also be used to analyze progression rates at 10, 12, 16, 18, 21, and 24 months, survival rates at 12, 18, 21, 27, and 30 months, and at 3 and 4 years, and for the analysis of overall response rates, and tumor control rate.
