The transfusion of naturally derived or modified cellular therapies, referred to as adoptive cell therapy (ACT), has demonstrated clinical efficacy in the treatment of hematologic malignancies and metastatic melanoma. In addition, cellular vaccination, such as dendritic cell–based cancer vaccines, continues to be actively explored. The manufacturing of these therapies presents a considerable challenge to expanding the use of ACT as a viable treatment modality, particularly at academic production facilities. Furthermore, the expanding commercial interest in ACT presents new opportunities as well as strategic challenges for the future vision of cellular manufacturing in academic centers. Current trends in the production of ACT at tertiary care centers and prospects for improved manufacturing practices that will foster further clinical benefit are reviewed herein.

Background: Gallbladder carcinoma (GBC) is a rare, aggressive malignancy comprising 0.5% of gastrointestinal cancers. It has poor survival outcomes due to its insidious onset, lack of standardized screening, and limited therapies. Advanced-stage diagnosis with liver, lymph node, and peritoneal metastasis is common, while bone metastasis is rare. The knowledge on bone metastasis in GBC is limited to case reports and small series, and its clinical significance is largely unexplored. Methods: The study extracted the demographic and clinical variables of patients with metastatic (M1) gallbladder adenocarcinoma from the Surveillance, Epidemiology, and End Results (SEER) database between 2011 and 2020. Descriptive statistics were used to analyze the demographic characteristics. The multivariate Cox regression analysis was used to calculate the hazard ratio. The overall survival (OS) was assessed using the Kaplan–Meier method, and the log-rank test was utilized to compare the survival between the groups. Results: A total of 2724 patients were included in the study. A total of 69% of the patients were female, and the median age was 68 (range 24–90+). A total of 7.4% of the patients had bone metastasis on diagnosis. The multivariate Cox analysis identified bone metastasis as an independent mortality risk factor in metastatic GBC (HR 1.50, p < 0.001). The patients were divided into two age groups: a younger age group (18–74 years) and an older age group (75+ years). In the younger group, the median OS with and without bone metastasis was 3 and 5 months, respectively (p < 0.0001). In the older age group, there was no significant difference in the OS between the patients with and without bone metastasis (p = 0.35). In the younger group who were treated with chemotherapy, the patients with bone metastasis had a significantly worse OS (median OS 5 months vs. 8 months, p < 0.0001). In the untreated group, the patients with bone metastasis in the younger age group had a significantly worse OS (median OS 1 month vs. 2 months, p = 0.014). In the patients with bone metastasis, those who did not receive chemotherapy had a significantly worse OS than those who were treated with chemotherapy in both age groups (younger age group: median OS 1 month vs. 5 months, p < 0.0001 and older age group: median OS 1 month vs. 5 months, p = 0.041). Conclusions: Our findings suggest that the presence of bone metastasis in gallbladder adenocarcinoma is an independent prognostic factor associated with unfavorable survival outcomes in the younger age group (18–74 years). However, in the older age group (75+ years), the presence of bone metastasis did not impact the survival. Treatment with chemotherapy was associated with extended survival in all patients. Thus, early detection and aggressive management of bone metastasis, including the consideration of chemotherapy, may be crucial in improving the OS and quality of life for individuals with gallbladder adenocarcinoma.

Tarlatamab, a bispecific T-cell engager targeting delta-like ligand 3 and CD3 on T cells, has generated impressive treatment response rates in relapsed extensive-stage SCLC and large cell neuroendocrine carcinoma. We performed a retrospective, multi-institutional analysis of 48 patients who received tarlatamab as standard of care to assess how safety and efficacy outcomes translate into real-world practice. Rates of cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome were 54% and 33%, respectively, with most being grades 1 to 2 in severity (100% and 87.5%). Of the 30 patients included in our efficacy analysis, the best overall response rate was 67% and disease control rate was 73%. With median follow-up of 5.7 months, median progression-free survival was 4.9 months (95% confidence interval: 4–not reached) and median overall survival was not reached (95% confidence interval: 4.8–not reached). Nine patients underwent molecular response assessment, with circulating tumor DNA trends corresponding with radiographic response. In this multicenter cohort study, tarlatamab continued to demonstrate encouraging response rates and progression-free survival; however, differences were observed in rates and timing of key treatment-associated toxicities compared with previous trial data.
