Affinity-optimized T cell receptors can enhance the potency of adoptive T cell therapy. Afamitresgene autoleucel (afami-cel) is a human leukocyte antigen-restricted autologous T cell therapy targeting melanoma-associated antigen A4 (MAGE-A4), a cancer/testis antigen expressed at varying levels in multiple solid tumors. We conducted a multicenter, dose-escalation, phase 1 trial in patients with relapsed/refractory metastatic solid tumors expressing MAGE-A4, including synovial sarcoma (SS), ovarian cancer and head and neck cancer ( NCT03132922 ). The primary endpoint was safety, and the secondary efficacy endpoints included overall response rate (ORR) and duration of response. All patients ( N  = 38, nine tumor types) experienced Grade ≥3 hematologic toxicities; 55% of patients (90% Grade ≤2) experienced cytokine release syndrome. ORR (all partial response) was 24% (9/38), 7/16 (44%) for SS and 2/22 (9%) for all other cancers. Median duration of response was 25.6 weeks (95% confidence interval (CI): 12.286, not reached) and 28.1 weeks (95% CI: 12.286, not reached) overall and for SS, respectively. Exploratory analyses showed that afami-cel infiltrates tumors, has an interferon-γ-driven mechanism of action and triggers adaptive immune responses. In addition, afami-cel has an acceptable benefit–risk profile, with early and durable responses, especially in patients with metastatic SS. Although the small trial size limits conclusions that can be drawn, the results warrant further testing in larger studies. In a phase 1 dose-escalation trial in patients with nine different types of solid tumors, MAGE-A4-specific T cells had an acceptable safety profile and exhibited an encouraging overall response rate in patients with synovial sarcoma.

The purpose of this study is to analyze the post-pandemic school adaptation process, the existence and/or effectiveness of adaptation programs, the obstacles encountered during this process, and thoughts and solutions for dealing with the difficulties. Two different surveys were delivered to schools via Google form, with 3,625 students and 1,822 teachers filling them out. According to the findings of the study, 86 percent of students were excited to return to school. Despite this, high academic demands of family and teachers, bullying, failure to manage time, the danger of being covid, teacher and friend relationships, and failing examinations are among the primary concerns of students. Teachers, contrary to student statistics, believe that students' adaptation to school after the pandemic is moderate. Teachers report that students struggle with following school rules, demonstrating constructive communication skills, emotion control, age-appropriate academic competencies, social skills, and life skills.
