Abstract Preclinical studies indicate that up-regulation of carbonic anhydrase (CA) by temozolomide (TMZ), via a mechanism requiring the proto-oncogene BCL-3, promotes resistance to therapy in glioblastoma (GBM) cells. Moreover, the CA inhibitor, acetazolamide (ACZ), sensitizes patient-derived GBM cells and xenografts to TMZ. These findings led to the current Phase I study investigating the safety and efficacy of adding ACZ to adjuvant TMZ in patients with newly diagnosed, MGMT-methylated malignant glioma. 24 patients were enrolled (23 GBM and one Grade III IDH-mutant astrocytoma), median age was 53.5 and mean KPS 91. ACZ was given on days 1-21 of each adjuvant TMZ cycle (250 mg BID days 1-7, increased to 500 mg BID days 8-21). No patient experienced the primary outcome of regimen limiting toxicity (RLT) and there were only three grade III adverse events deemed likely unrelated to ACZ. For the secondary endpoints of overall and progression free survival (OS and PFS, respectively), only the 23 GBM patients were included (22 IDH-wildtype and 1 IDH-mutant). From diagnosis, median PFS was 18.8 months (95% CI: 10.4-23.0) and median OS was 25.0 months (95% CI: 19.9-28.4). Median time from diagnosis to consent was 2.9 months. As of April 2021, only 7 of 23 deaths had occurred. 2-year OS% was 68.2%. Further analysis of secondary endpoints including 6-month objective response rate (ORR) and biomarker analysis of BCL-3 by IHC will be available in the coming months. In sum, the data indicate that addition of ACZ to TMZ is safe and does not lead to reduced TMZ dosing. Also, compared to historical data, interim outcomes suggest that addition of ACZ may substantially improve PFS and 2-year overall survival. These findings support the hypothesis that ACZ acts as a chemosensitizer of alkylating chemotherapy in GBM and support examination of this regimen in a randomized, placebo-controlled study.

Abstract Genomic aberrations in the cell cycle and mTOR pathways have been reported in diffuse pontine gliomas (DIPG) and high-grade gliomas (HGG). Dual inhibition of CDK4/6 (ribociclib) and mTOR (everolimus) has strong biologic rationale, non-overlapping single-agent toxicities, and adult clinical experience. The maximum tolerated dose (MTD) and/or recommended phase two dose (RP2D) of ribociclib and everolimus administered during maintenance therapy following radiotherapy was determined in the phase I study as a rolling 6 design. Ribociclib and everolimus were administered once daily for 21 days and 28 days, respectively starting two-four weeks post completion of radiotherapy. All HGG patients and any DIPG patient who had undergone biopsy were screened for RB protein by immunohistochemistry. Eighteen eligible patients enrolled (median age 8 years; range: 2–18). Six patients enrolled at dose levels 1,2, and 3 without dose limiting toxicities (DLT). Currently, five patients are enrolled at dose level 3 expansion cohort. The median number of cycles are 4.5 (range: 1–20+). Among the expansion cohort, one dose limiting toxicity included a grade 3 infection and one patient required a dose reduction in course 3 due to grade 3 ALT and grade 4 hypokalemia. The most common grade 3/4 adverse events included neutropenia. Preliminary pharmacokinetic studies on 12 patients suggest an impact of ribociclib on everolimus pharmacokinetics. The MTD/RP2D of ribociclib and everolimus following radiotherapy in newly diagnosed DIPG and HGG is anticipated to be 170 mg/m2/day x 21 days and 1.5 mg/ m2/day every 28 days which is equivalent to the adult RP2D.

Abstract BACKGROUND Diffuse intrinsic pontine glioma (DIPG) constitutes 80% of pediatric brain stem tumors with a median survival of 12 months. The PI3K/AKT/mTOR pathway is a key oncogenic driver of this tumor. Targeting the chromatin dysregulation through HDAC inhibition, demonstrated benefit in vivo and vitro studies. We completed the first study as a multi-targeted therapy using SAHA and temsirolimus in pediatric DIPG. METHODS After receiving institutional IRB approval, we enrolled 6 patients on this phase I study using a 3 + 3 statistical design. Patients were divided into stratum 1 and stratum 2, based on newly diagnosed or relapsed DIPG respectively. Stratum I patients received radiation therapy concurrently with vorinostat, followed by maintenance therapy with vorinostat and temsirolimus for 10 cycles (28 day cycle), while in stratum II patients received vorinostat and temsirolimus for 12 cycles. Neuroimaging including diffusion tensor imaging were evaluated where feasible. RESULTS Three patients were enrolled in each of the stratum. One patient in stratum 1 completed therapy, 2 other demonstrated progressive disease (PD) after 4th and 1st cycle of maintenance therapy respectively. In stratum 2 all patients progressed 2 months after the start of therapy. However no dose-limiting toxicity (DLT) was noted. The patient in stratum 1 who completed therapy, remained free of PD 21 months after diagnosis with continued improvements in the volume of enhancing and T2 hyperintense disease. CONCLUSION Although no significant benefit was seen as compared to historical controls during this study, no dose limiting toxicity was noticed with this treatment.

AbstractAsunercept (company code APG101 [Apogenix AG]; company code CAN008 [CANbridge Pharmaceuticals]) is a novel glycosylated fusion protein that has shown promising effectiveness in glioblastoma. This Phase I study was initiated to evaluate the tolerability and safety of asunercept in combination with standard radiotherapy and temozolomide (RT/TMZ) in Asian patients with newly diagnosed glioblastoma. This was the Phase I portion of a Phase I/II open label, multicenter trial of asunercept plus standard RT/TMZ. Adults with newly-diagnosed glioblastoma received surgical resection followed by standard RT/TMZ plus asunercept 200 mg/week (Cohort 1) or 400 mg/week (Cohort 2) by 30-min IV infusion. The primary endpoint was the safety and tolerability of asunercept during concurrent asunercept and RT/TMZ; dose-limiting toxicities were observed for each dose. Secondary endpoints included pharmacokinetics (PK) and 6-month progression-free survival (PFS6). All patients (Cohort 1, n = 3; Cohort 2, n = 7) completed ≥ 7 weeks of asunercept treatment. No DLTs were experienced. Only one possibly treatment-related treatment emergent adverse event (TEAE), Grade 1 gingival swelling, was observed. No Grade > 3 TEAEs were reported and no TEAE led to treatment discontinuation. Systemic asunercept exposure increased proportionally with dose and showed low inter-patient variability. The PFS6 rate was 33.3% and 57.1% for patients in Cohort 1 and 2, respectively. Patients in Cohort 2 maintained a PFS rate of 57.1% at Month 12. Adding asunercept to standard RT/TMZ was safe and well tolerated in patients with newly-diagnosed glioblastoma and 400 mg/week resulted in encouraging efficacy.Trial registration NCT02853565, August 3, 2016.
