ABSTRACT

OBJECTIVE: This study was designed to assess the efficacy and safety of cadonilimab monotherapy, a first-in-class, bi-specific PD-1/CTLA-4 antibody, in patients with previously treated recurrent or metastatic nasopharyngeal carcinoma (R/M-NPC). PATIENTS AND METHODS: This multicenter, open-label, single-arm, phase II clinical trial enrolled patients with R/M-NPC who had failed first-line platinum-based chemotherapy and second-line single agent or combined chemotherapy, and immunotherapy-naive. Patients received cadonilimab for 6 mg/kg once every 2 weeks (Q2W). The primary endpoint was objective response rate (ORR) in full analysis set (FAS) assessed by investigators according to RECIST v.1.1. The secondary endpoint included progression-free survival (PFS), overall survival (OS), duration of response (DoR), time to response (TTR) and safety. RESULTS: A total of 23 patients were assessed. The median time from first dose to data cutoff was 16.56 (range, 0.8-25.2) months. ORR was 26.1 % (95 %CI:10.2-48.4). The ORR were 44.4 % (95 %CI: 13.7-78.8) and 14.3 % (95 %CI:1.8-42.8) in patients with tumor PD-L1 expression ≥50 % and <50 %, respectively. ORR was achieved in 40.0 % (95 %CI:12.2-73.8) of patients with EBV-DNA level <4000 IU/ml (n = 10) and 15.4 % (95 %CI:1.9-45.4) of those with ≥4000 IU/ml. The median PFS was 3.71 months (95 %CI: 1.84-9.30). respectively. Median OS was not reached, and the 12-month OS rate was 79.7 % (95 % CI:54.5-91.9). Only two patients (8.3 %) experienced Grade ≥3 treatment-related adverse events (TRAEs) with hypothyroidism (30.4 %), rash (21.7 %) and pruritus (21.7 %) being the most prevalent TRAEs. CONCLUSION: Cadonilimab monotherapy demonstrated a promising efficacy and manageable toxicity in patients with previously treated R-M/NPC and provide an efficacious salvage treatment option.

ABSTRACT

ABSTRACT Introduction: Table tennis is demanding in terms of athletes' physical fitness and muscular responsiveness. Excellent physical fitness is important to ensure a high technical level. It can also play an essential role in injury prevention. Objective: Explore the correlation between table tennis players' movements and their displacements. Methods: Volunteer professional competitors underwent a private 16-week quality speed training program. In this experiment, athletes had their speed analyzed before and after training. Mathematical and statistical analyses were performed on the collected data. Some discussions are made to improve the reflex ability of the athletes. Results: The table tennis players' physical fitness and action response capacity were explored. After physical exercise, the players' reflex ability improved. There were statistically significant differences in the data (P<0.05). Conclusion: The results show that special training improves athletes' reaction speed, endurance, strength, coordination, and flexibility. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


RESUMO Introdução: O tênis de mesa é um esporte exigente quanto à aptidão física e à capacidade de resposta muscular do atleta. A excelente aptidão física é importante para assegurar o elevado nível técnico. Também pode desempenhar um papel essencial na prevenção de lesões. Objetivo: Explorar a correlação entre os movimentos dos jogadores de tênis de mesa e seus deslocamentos. Métodos: Competidores profissionais voluntários foram submetidos a um programa particular de treinamento de qualidade de velocidade com 16 semanas de duração. Nesta experiência, os atletas tiveram sua velocidade analisada antes e depois do treinamento. Análises matemáticas e estatísticas foram realizadas sobre os dados coletados. Algumas discussões são feitas para melhorar a capacidade no reflexo dos atletas. Resultados: Explorou-se a aptidão física dos jogadores de tênis de mesa e a capacidade de resposta à ação. Após o exercício físico, a capacidade de reflexão dos jogadores melhorou. Houve diferenças estatisticamente significativas nos dados (P<0,05). Conclusão: Os resultados mostram que o treinamento especial desenvolvido melhora a velocidade de reação dos atletas, a resistência, a força, a coordenação e a flexibilidade. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.
