Detailed Description
AXL1717, as a ready-to-use suspension of picropodophyllin for oral administration, will be distributed in bottles for single use at a concentration of 25 mg/mL. Fixed doses will be used, i.e. there are no adjustments for weight or body surface. There will be no randomization or blinding in the study.
The trial will be divided in two phases. In the first phase, 10-20 patients will be enrolled and treated with 300-520 mg BID of AXL1717 for 28 days. The primary endpoint of the first phase is to determine the recommended Phase 2 dose (RP2D) of AXL1717 in patients with recurrent or progressive glioblastoma and to assess the safety and toxicity of AXL1717 in this patient population. The study has a 3+3 design and the first cohort will be treated with 400 mg AXL1717 BID for 28 days repeated in up to 5 cycles. If dose-limiting toxicity (DLT) such as neutropenia occurs, dosing will be interrupted and the individual patient will, following normalization, be restarted on the same or a lower dose level according to standardized procedure. If two or three of the first 3 patients on a specific dose level experience a DLT during the first 28 days of treatment with AXL1717, the following patients will be treated with a lower dose level. If one DLT occurs during the first 28 days of dosing in the first 3 three patients another 3 patients will be treated with the same dose level. If 2 of the 6 patients display DLT, the next patients will be treated with a lower dose level. The highest dose level without DLT or with maximally one DLT out of 6 patients will be the RPTD. All assessments with respect to dose adjustments for subsequent cohorts will be done during the first 28 days of treatment. Non-progressing patients may be treated for a total of five 28-day cycles (24 weeks).
In the second phase, 12 patients will be enrolled and treated with the identified RP2D of AXL1717 for 28 days repeated in five cycles. The primary endpoints of phase II is to assess the proportion of patients who are progression-free at 24 weeks and to assess safety, tolerability, and adverse event profile of AXL1717.

Experimental: Phase 1: AXL1717, 300mg
In the first phase, 10-20 patients will be enrolled and treated with 300mg (original range of starting dose was 300-520mg) BID of AXL1717 for 28 days.
The primary endpoint of the first phase is to determine the recommended Phase 2 dose (RP2D) of AXL1717 and to assess the safety and toxicity of AXL1717.
The study has a 3+3 design and the first cohort will be treated with 300 mg AXL1717 BID for 28 days repeated in up to 5 cycles.
The highest dose level without DLT or with maximally one DLT out of 6 patients will be the RP2D.
Non-progressing patients may be treated for a total of five 28-day cycles (24 weeks).
