Clinical Trial Summary

This is an open label study to determine the safety and preliminary evidence of a therapeutic effect of azeliragon in patients with newly diagnosed glioblastoma receiving concurrent radiation and temozolomide.

Description:

Patients will receive involved field radiation therapy and temozolomide consisting of fractionated focal irradiation in daily fractions of 2 Gy given 5 days/week for 6 weeks, for a total of 60 Gy, plus concomitant daily temozolomide (TMZ; 75 mg/m2/day, 7 days/week from the first to the last day of radiotherapy), followed by six cycles of adjuvant TMZ (150-200 mg/m2/day for 5 days during each of six 28-day cycles.

Patients will receive azeliragon for up to 2 years or as long as the patient and study investigator feel that a therapeutic benefit is possible.

Patients will be accrued in groups of six starting with Dose Level 1. Escalation will continue as described in Table 2 until stopping rules are met or the highest defined dose level is reached. If Dose Level 1 is deemed intolerable, the trial will be closed to accrual.

The dose limiting toxicities (DLT) evaluation period will be defined as 28 days from initiation of dosing. The severity of adverse events will be graded according to CTCAE v 5.0. For the purpose of dose-finding, any listed AEs occurring during the DLT period, which are attributable (definite, probable, possible) to azeliragon will be classified as a DLT. In addition, the RP2/3D will take into account dose-reductions, treatment interruptions, discontinuation, and toxicities after the DLT period.

RP2/3D was defined as the dose with 6 patients treated at that dose level with ≤ 1 DLT observed.

2. Patients with a serious active infection (such as a wound infection requiring parenteral antibiotics) at the time of inclusion or other serious underlying medical conditions that would impair the ability of the patient to receive protocol treatment

3. Patients with any condition (e.g. psychological, geographical, etc.) that does not permit compliance with the protocol.

4. Patients who have had treatment with any investigational cancer drug prior to the first dose of study treatment.

5. Patient has experienced an increase of ECOG to > 2 between Screening and the time of first dose with azeliragon.

6. Patients receiving CYP2C8 inhibitors

7. Patient is unwilling or unable to comply with study procedures, including, but not limited to self-administration of oral medication.

8. Patients with a gastrointestinal condition that could interfere with swallowing or absorption.

9. Females of childbearing potential who are sexually active or males with female partners of childbearing potential, where either the female or the male is unwilling to use a highly effective method of contraception during the trial and for 6 months after the last administration of azeliragon.

10. Patients with concurrent participation in another interventional clinical trial or use of another investigational agent within 14 days of starting azeliragon. Patients who are participating in non-interventional clinical trials (e.g., QOL, imaging, observational, follow-up studies, etc.) are eligible, regardless of the timing of participation.
