Phase Ib/Ii Study Of Lacnotuzumab In Combination With Spartalizumab In Patients With Advanced Malignancies, Jibran Ahmed, Bettzy Stephen, Yali Yang, Evan Kwiatkowski, Chinenye Lynette Ejezie, Shubham Pant

Faculty, Staff and Student Publications

INTRODUCTION: Blocking the colony-stimulating factor 1 (CSF-1) signal on tumor-associated macrophages can lead to an upregulation of checkpoint molecules, such as programmed cell death ligand 1 (PD-L1), thus causing resistance to this blockade. Combining spartalizumab (PDR001), a high-affinity, ligand-blocking, humanized anti-PD-1 immunoglobulin G4 antibody, with lacnotuzumab (MCS110), a high-affinity, humanized monoclonal antibody directed against human CSF-1 can potentially overcome this resistance.

METHODS: This was a multicenter, phase Ib/II trial using a combination of spartalizumab with lacnotuzumab in patients with advanced cancers, including anti-PD-1/PD-L1 treatment-resistant melanoma, and anti-PD-1/PD-L1 treatment-naïve triple-negative breast cancer, pancreatic cancer, and endometrial cancer (ClinicalTrials.gov identifier: NCT02807844).

Acoustic-Perceptual Relations Between Fundamental Frequency And Expressiveness In Speakers With Hypokinetic Dysarthria, Alena Portnova

All Graduate Theses and Dissertations, Fall 2023 to Present

Hypokinetic dysarthria is a motor speech disorder that occurs in patients with Parkinson’s disease (PD) and affects not only their speech intelligibility but also how their attitudes and emotions are perceived by listeners. People with PD have been judged as less happy, involved, friendly, and interested based only on their speech samples. A lack of speech expressiveness is one of the characteristics that is likely to be related to these negative listener judgments. Specifically, it has been suggested that a lack of fundamental frequency (F0) variation reduces speakers’ ability to express various emotions. To investigate whether speech expressiveness is related …
