Item Clinical and Biological Activity of Chemoimmunotherapy in Advanced Endometrial Adenocarcinoma: A Phase II Trial of the Big Ten Cancer Research Consortium(American Association for Cancer Research, 2022) Barber, Emma L.; Chen, Siqi; Pineda, Mario Javier; Robertson, Sharon E.; Hill, Emily K.; Teoh, Deanna; Schilder, Jeanne; O’Shea, Kaitlyn L.; Kocherginsky, Masha; Zhang, Bin; Matei, Daniela; Obstetrics and Gynecology, School of MedicinePurpose: The objective of this study was to assess the efficacy and safety of pembrolizumab in combination with standard carboplatin/paclitaxel in patients with advanced endometrial cancer (EC). Patients and methods: This single-arm, open-label, multi-center phase II study enrolled patients with RECIST measurable advanced EC. Patients could have received < 1 prior platinum-based regimen and < one non-platinum chemotherapy. The primary endpoint was objective response rate (ORR). Planned sample size of 46 subjects provided 80% power to detect 15% ORR improvement compared to historical control rate of 50%. Results: 46 patients were enrolled, and 43 were evaluable for ORR. Median age was 66 (range: 43-86). Thirty-four (73.9%) patients had recurrent and 12 (26.1%) primary metastatic EC. Patients received carboplatin AUC 6, paclitaxel 175mg/m2 and pembrolizumab 200mg IV every 3 weeks for up to 6 cycles. ORR was 74.4% (32/43), higher than historic controls (p = 0.001). Median PFS was 10.6 months (95% CI 8.3-13.9 months). The most common grade 1-2 treatment related adverse event (TRAEs) included anemia (56.5%), alopecia (47.8%), fatigue (47.8%) and neuropathy (13%), while the most common grade 3-4 TRAEs were lymphopenia, leukopenia, and anemia (19.6% each). High-dimensional spectral flow cytometry (CyTEK) identified enrichment in peripheral CD8+ and CD4+ T cell populations at baseline in responders. The CD8+ T cell compartment in responders exhibited greater expression levels of PD-1 and PD-L1 and higher abundance of effector memory CD8+ cells compared to non-responders. Conclusions: Addition of pembrolizumab to carboplatin and paclitaxel for advanced EC was tolerated and improved ORR compared to historical outcomes.Item Hemostatic efficacy of an advanced bipolar sealer in open gynecologic, thoracic, and colectomy procedures: A prospective cohort study(Elsevier, 2020) Schilder, Jeanne; Anderson, David; Shah, Fatima; Holcomb, Bryan; Shah, Ahmar; Fullarton, Grant; Ashraf, Shazad; Fegan, Scott; Paterson, Hugh; Schwiers, Michael L.; Singleton, David W.; Waggoner, Jason R.; Fryrear, Raymond, II; Robb, Bruce W.; Surgery, School of MedicineBackground An advanced bipolar (ABP) tissue sealer designed for division of major vessels in open procedures was evaluated in a prospective post-market study. The objective was to provide clinical data for assessment of vessel transection, hemostatic performance and ease of use of the ABP device during open colectomy, gynecologic, and thoracic operations. Materials and methods The ABP test device was used in colectomy (n = 36), gynecologic (n = 44), and thoracic (n = 21) procedure groups. Vessels transected with the ABP device were graded intraoperatively on a hemostasis scale of 1–4, defined as follows: Grade1, no bleeding; Grade 2, minor bleeding with no intervention; Grade 3, minor bleeding requiring touchup with the test device or monopolar cautery; and Grade 4, significant bleeding requiring intervention with any additional hemostatic product. The primary performance measure was the percentage of vessels that achieved hemostasis grades ≤3. The primary safety endpoint was the summarization of all ABP device-related adverse events (AEs). Results For all three procedure groups together, 302 (96.2%) of 314 total vessel transections were scored as hemostasis grades ≤ 3, including 270 (86.0%) that were rated Grade 1. Twelve transections (3.8%) were Grade 4, which included 9 vessels transected in the gynecologic group and 3 in the thoracic group. Three subjects experienced a total of 4 device-related AEs, consisting of hematoma, hypotension, procedural pain, and superficial thermal burn. All 4 device-related AEs were mild in severity. Conclusion The advanced bipolar device exhibited effective hemostasis, an acceptable safety profile, and ease of use during colectomy, thoracic, and gynecologic procedures.
