Précis: Glaucoma patients with significant visual field defects show poorer driving performance, higher collision risks, and a greater likelihood of driving cessation. They face difficulties with lane maintenance, slower hazard responses, and self-regulation while driving. Purpose: Glaucoma is a chronic, progressive optic neuropathy associated with visual field (VF) defects, which in advanced disease has been shown to affect patients’ activities of daily living. This systematic review qualitatively analyzes existing literature that explores the impact of glaucomatous VF loss on the driving performance of glaucoma patients, the extent of driving limitation and cessation, as well as the risk of motor vehicle collisions (MVCs). Methods: A literature search of MEDLINE and Embase (via Ovid), PubMed, Cochrane Library, and Web of Science databases was performed for studies published from 2003 to 2023, with the terms “glaucoma,” “visual field defect/disorder,” and “driving,” followed by selective vetting based on inclusion criteria. Within studies, data pertaining to study design, subject demographics, VF defect characteristics, driving performance and related outcomes were extracted. Results: Initial search yielded 835 studies, with 20 studies selected. Three more studies were included through hand-searching, with a total of 23 studies included for final review. Moderate to severe VF defects resulted in poorer driving performance, with slower response times to road hazards, decreased ability for lane maintenance, and increased difficulty driving at night. Patients with more severe VF defects and with bilateral glaucoma were more likely to limit or cease driving compared with those with milder and unilateral glaucoma. A greater severity of VF loss was associated with a higher risk of MVCs. Conclusion: More severe glaucomatous VF and bilateral glaucoma is associated with worse driving performances and a higher risk of MVCs, in both simulator and real-world settings.
Abstract CT105: Preliminary results from the Phase I part of a first-in-human Phase I/II study of HH2853, an EZH1/2 inhibitor, in patients with relapsed/refractory non-Hodgkin lymphomas or advanced solid tumors
Abstract Background: The dysregulation of polycomb repressive complex 2 (PRC2) promotes tumorigenesis and progression. Two therapeutic agents targeting enhancer of zeste homolog (EZH) 2 or EZH1/2, the catalytic subunits of PRC2, have been approved in several cancer types. HH2853 is a novel selective EZH1/2 dual inhibitor, which has demonstrated superior anti-tumor efficacy to tazemetostat (EZH2 inhibitor approved by FDA) in various preclinical models. Methods: This is a first-in-human, open-label, multi-center, phase (Ph) I/II study of HH2853 in patients (pts) with relapsed/refractory (r/r) non-Hodgkin lymphomas (NHLs) or advanced solid tumors. HH2853 was administered orally twice daily (BID) on a continuous 28-day treatment cycle. Ph I consist of two parts: dose escalation part adopting accelerated titration followed by a Bayesian optimal interval design and dose extension part. Dose limiting toxicity (DLT) was evaluated during the 1st cycle in dose escalation. Safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary anti-tumor activity of HH2853 were explored in this Ph I study. Results: As of Oct 19, 2022, a total of 57 pts, including 50 pts with solid tumors and 7 pts with r/r follicular lymphoma (FL), were enrolled from 12 sites in China and the US. Twenty-five (43.9%) pts received ≥3 lines of prior systemic therapies. Six dose levels(50 mg, 100 mg, 200 mg, 400 mg, 600 mg and 800 mg)were evaluated. DLTs were observed in 2 of 8 DLT evaluable pts at 800 mg: one grade 3 platelet count decreased and one grade 3 diarrhea. A conclusive maximal tolerated dose was not reached. The most common treatment-related adverse events (TRAE) were diarrhea (45.6%), blood bilirubin increased (35.1%), white blood cell count (WBC) decreased (26.3%), platelet count decreased (26.3%), rash (24.6%) and anemia (22.8%). The most common ≥grade 3 TRAEs included anemia (8.8%), platelet count decreased (7.0%), WBC decreased (5.3%) and diarrhea (5.3%). TRAEs leading to dose interruption or reduction were reported in 17.5% and 8.8% pts respectively. No TRAE led to dose discontinuation or death. PK data indicated dose-related increase in exposure from 50 to 600 mg. PD data showed a significant inhibition (maximum reached >90%) of H3K27me3 in granulocytes and monocytes at 400-800 mg. Tumor responses were observed in 7 pts from 200 to 800 mg in multiple tumor types, including complete response in 1 patient with FL, partial response in 3 pts with epithelioid sarcoma, 2 pts with FL and 1 patient with malignant rhabdoid tumor of pancreas. Conclusions: This first-in-human study of HH2853 showed a manageable safety profile and promising anti-tumor activity in multiple tumor types, supporting further exploration in NHLs and solid tumors after recommended Ph II dose is determined.Clinical trial information: NCT04390737 Citation Format: Zhengfu Fan, Jin Wang, Meiyu Fang, Johnston Patrick, Tun Han, David Sommerhalder, Jifang Gong, Jilong Yang, Yun Yang, Javier Munoz, Yuqin Song, Zhiming Li, Xian'an Li, Qiuying Ma, Jinming Han, Lin Shen, Jun Zhu.
