Safety Issues

Abstract BACKGROUND OS2966 is a first-in-class, humanized and deimmunized monoclonal antibody which antagonizes CD29/β1integrin, a mechanosignaling receptor prominently upregulated in glioblastoma. Preclinical studies in mice and non-human primates have demonstrated safety and encouraging efficacy. A two-part, ascending concentration, phase I clinical trial was therefore initiated to evaluate the safety and feasibility of delivering OS2966 directly to the site of disease via convection-enhanced delivery (CED) in recurrent high-grade glioma patients. METHODS This study has a 2-part design: In part 1, patients undergo stereotactic tumor biopsy followed by placement of a multiport CED catheter for delivery of OS2966 to the bulk contrast enhancing tumor. Subsequently, patients undergo a clinically-indicated tumor resection followed by placement of two CED catheters and delivery of OS2966 to the surrounding tumor-infiltrated brain. A unique concentration-based accelerated titration design is utilized for dose escalation. Given availability of pre and post infusion samples, pharmacodynamic data will be analyzed to explore mechanism of action of OS2966. RESULTS Two subjects have been treated at two corresponding dose levels (0.2mg/mL and 0.4 mg/mL). No dose-limiting toxicity or unexpected safety issues have been identified. To date, reported adverse events were mild (i.e., grade 1) and consistent with underlying disease and surgical procedures. No adverse events were attributed to OS2966 or CED catheter placement. Further, no clinically significant changes from baseline neurological exam have been noted for either patient through initial follow-up. Maximal tumor coverage and concomitant gross total resection were achieved for both patients. Tumor volume measured 1.63 cm3 and 16 cm3 for Patient 1 and 2 respectively with an intratumoral Vd/Vi ratio of 1.3. and 0.94. Pharmacodynamic analysis via tissue-level biomarkers is ongoing and will be presented. CONCLUSION Initial data demonstrates the safety and feasibility of direct intracranial delivery of OS2966.

Abstract BACKGROUND High-grade gliomas (HGG) are characterized by dysregulated metabolism, utilizing glycolysis for energy production to support unrestricted growth. BPM 31510, an ubidecarenone (coenzyme Q10) containing lipid nanodispersion, causes a switch in cancer energy sourcing from glycolysis towards mitochondrial oxidative phosphorylation in vitro, reversing the Warburg effect and suggesting potential as an anti-tumor agent. The current study is a phase I study of BPM31510 + vitamin K in GB with tumor growth after bevacizumab (BEV). METHODS This is an open-label phase I study of BPM31510 continuous infusion with weekly vitamin K (10mg IM) in HGG patients using an mTPI design, starting at 110mg/kg, allowing for a single dose de-escalation and 2 dose-escalations. Patients had received first-line ChemoRadiation and were in recurrence following a BEV containing regimen. RESULTS 9 eligible and evaluable patients completed the 28 day DLT period. 8 patients had primary GB, 1 had anaplastic astrocytoma with confirmed pathologic transformation to GB. Median age was 55 years (27–67) and median KPS 70 (60–90) at enrollment. 4 patients were treated at the highest dose 171mg/kg, where there was a single DLT: Grade 3 AST & ALT. The most common grade 1–2 AEs possibly, probably or definitely related to drug were elevated AST, rash, and fatigue, each occurring in 3 patients. Median OS for 9 eligible/evaluable patients was 128 days (95% CI: 48–209) while PFS was 34 days (CI of mean 8.9). 3 patients are currently alive; 2 patients have survived >1 year. PK/PD data are being processed and will be presented. CONCLUSION This study confirms that BPM 31510 + vitamin K is safe and feasible in treatment-refractory HGG patients. Though this study demonstrates safety at 171mg/kg, the proposed dose for future studies in GB, based on additional pre-clinical and non-GB clinical data is 88mg/kg.

2543 Background: BPM31510 is an ubidecarenone-lipid conjugate nanodispersion in clinical development for advanced malignancies, including high grade glioma (HGG). BPM31510’s anti-cancer effect is mediated by induction of mitochondrial superoxide and activation of cell death in glioblastoma models. Herein, we present preliminary pharmaco-kinetic and dynamic data, and survival from a phase I study of BPM31510 + Vitamin K in HGG with progression after bevacizumab (BEV). Methods: This was an open-label phase I study of BPM31510 continuous infusion with Vitamin K (10mg IM qweek) using a mTPI design, starting at 110mg/kg 2X/week, allowing 2 dose escalations & 1 de-escalation. Patients had received ChemoRT and were in recurrence after BEV. Results: Of 12 patients treated with BPM31510, 9 completed the 28-day DLT period. 2 patients came off study for progressive disease; 1 patient after asymptomatic hemorrhage into tumor bed (G1). 10 patients had primary GB, 2 had AA. Median age was 54.5yo (27-67) and KPS 70 (60-90). On Day 1 of BPM31510, a dose dependent increase in Cmax was observed; Tmax values were similar for all doses. AUC was linear with dose escalation. For all doses, Day 4 Cmax values were higher compared to Day 1. In contrast there was variable decrease in Tmax (table). Of evaluable patients, 4 patients received the highest dose 171mg/kg, where a single patient experienced DLT: G3 AST & ALT. The most common grade 1/2 AEs were elevated AST, rash, and fatigue, each occurring in 4 patients. The mOS for 9 eligible/evaluable patients was 128 days (95% CI: 48-209) while PFS was 34 days (95% CI of mean 8.9). Two patients are currently alive >12 months. Conclusions: BPM31510 + vitamin K demonstrated a safe profile to maximum dose of 171mg/kg twice/week with potential therapeutic utility in treatment-refractory HGG patients. Multi-omic molecular profiles characterizing AE and response to be reported from the study will be investigated for next phase of clinical development. Clinical trial information: NCT03020602 .
